Brakes
What has a negative effect on braking efficiency?
Wear-and-tear
Wear-and-tear to the brake pads is greatly dependent on the operating conditions
of the vehicle and your style of driving. Particularly if you drive a great deal in
towns and over short distances or if you adopt a sporty style of driving, it may be
necessary to have the thickness of the brake pads inspected at a specialist garage
between the service inspections.
Wet roads or road salt
There may be a certain delay before the brakes take full effect under certain con-
ditions such as when driving through water, during heavy rain showers or after
the vehicle has been washed in an automatic vehicle wash, since the brake discs
and brake pads may be moist or even have a coating of ice on them in winter. You
should dry the brakes as soon as possible by applying and releasing the brakes
several times.
There also may be a certain delay before the full braking efficiency is available
when driving on roads which have been treated with road salt if you have not
used the brakes for some considerable time beforehand. The layer of salt on the
brake discs and brake pads must first be rubbed off when you apply the brakes.
Corrosion
Corrosion on the brake discs and dirt on the bake pads occur if the vehicle has
been parked for a long period and if you do not make much use of the braking sys-
tem.
We recommend cleaning the brake discs by firmly applying the brakes at a fairly
high speed if you do not make much use of the braking system or if surface corro-
sion is present ⇒  .
Faults in the brake surface
If you notice that the braking distance has suddenly become longer and that the
brake pedal can be depressed further, it is possible that a brake circuit of the dual-
circuit brake system has failed. Drive, in such cases, to the nearest specialist ga-
rage without delay in order to have the problem rectified. Drive at a reduced
speed while on your way to the dealer and adapt your style of driving to the high-
er brake pedal pressure required. Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system. The
level of the brake fluid is monitored electronically
⇒ page 28, Brake system . WARNING
● Only apply the brakes for the purpose of drying and cleaning the brake
discs if the traffic conditions permit this. Do not place any other road users in
jeopardy.
● When retrospectively mounting a front spoiler, solid wheel hubs etc. one
must ensure that the air supply to the front wheel brakes is not reduced oth-
erwise the braking system could run too hot.
● Allow for the fact that new brake pads do not achieve their full braking ef-
ficiency until approximately 200 kilometres. New brake pads must be first
“run in
” before they develop their optimal friction force. You can, however,
compensate for this slightly reduced braking force by increasing the pressure
on the brake pedal. This guideline also applies to any new brake pads installed
at a future date. CAUTION
● Never allow the brakes to rub by applying slight pressure if you do not wish to
brake the vehicle. This causes the brakes to overheat and can also result in a lon-
ger braking distance and excessive wear.
● Before negotiating a steep downhill section, please reduce your speed, shift
down into the next lower gear (manual gearbox) or select a lower driving stage
(automatic gearbox). This enables you to make full use of the braking power of
the vehicle and reduces the strain on the brakes. Any additional braking should be
done intermittently, not continuously. Note
The brake light flashes automatically in case of an emergency braking at speeds
greater than 60 km/h or with the intervention of the ABS, which lasts longer than
1.5 seconds. After the speed was reduced below 10 km/h or the vehicle was stop-
ped, the brake light stops flashing and the hazard warning light system switches
on. The hazard warning light system is switched off automatically after accelerat-
ing or driving off again.  157

Brake booster
The brake booster boosts the pressure which you generate with the brake pedal.
The necessary pressure is only generated when the engine is running. WARNING
● Never switch off the engine before the vehicle is stationary.
● The brake booster only operates when the engine is running. Greater
physical effort for braking is required when engine is switched off. Because if
you do not stop as normal, this can cause an accident and severe injuries.
● While stopping or braking with a vehicle with a petrol engine and manual
transmission in the low rev range, press down on the clutch pedal. If you fail
to do so, the result may be an impairment of the function of the power brake.
You will apply a greater force to the brake pedal which you are usde to - dan-
ger of accident! 
Antilock brake system (ABS) ABS prevents the wheels locking when braking.
General
The ABS contributes significantly to enhancing the active safety of your vehicle.
Compared to a car not fitted with the ABS brake system, you are able to retain op-
timal steering ability even during a full brake application on a slippery road surface
because the wheels do not lock up.
You must not expect, however, that the braking distance will be shorter under all
circumstances as a result of the ABS. The braking distance for example on gravel
and fresh snow, when you should anyway be driving slowly and cautiously, will be
longer.
Operating principle
The brake pressure will be reduced on a wheel which is rotating at a speed which
is too low for the speed of the vehicle and tending to lock. This control cycle is
noticeable from a pulsating movement of the brake pedal which is accompanied
by noises. This is consciously intended to provide the driver with the information
that the wheels are tending to lock (ABS control range). You must always keep the
brake pedal depressed to enable the ABS to optimally control the brake applica-
tion in this braking range. Never interrupt the application of the brakes! As soon as the vehicle speed has increased to about 20 km/hour an automatic
test procedure is conducted during which you will be able to hear a pumping noise
for about 1 second. WARNING
● The ABS can also not overcome the physical limits of your vehicle. Please
do not forget this, particularly when driving on icy or wet road surfaces. If the
ABS is operating within the control range, adapt your speed immediately to
the conditions of the road surface and the traffic situation. The increased
safety offered by the ABS must not tempt you to take greater risks than oth-
erwise - risk of an accident!
● The normal braking system is still fully functional if there is an ABS fault.
Visit a specialist garage immediately and adjust your style of driving according
to the damage to the ABS as you will not know how great the damage is and
the limitation it is placing on the braking efficiency. Note
● A warning light comes on if a fault occurs in the ABS system  ⇒  page 27.
● Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combi-
nation of tyres and wheels) can influence the function of the ABS ⇒

Accessories, changes and replacement of parts. 
Brake Assist During a severe brake application (e.g. if a hazard exists), the Brake Assist increa-
ses the braking force and thus makes it possible to rapidly produce the pressure
required in the brake system.
The majority of drivers do apply the brakes in good time in dangerous situations,
but do not depress the brake pedal with sufficient pressure. Consequently, it is
not possible for the car to achieve its maximum deceleration and the car covers a
greater distance than necessary.
The Brake Assist is activated by the very quick operation of the brake pedal. In
such cases, a much greater braking pressure exists than during a normal brake ap-
plication. This makes it possible, even with a relatively low resistance of the brake
pedal, to produce an adequate pressure in the brake system in the shortest possi-
ble time, which is required for maximum deceleration of the car. You must apply
the brake pedal firmly and hold it in this position in order to achieve the shortest
possible braking distance. £158
Intelligent Technology

The Brake Assist is able to help you achieve a shorter braking distance in emer-
gency situations by rapidly producing the pressure required in the brake system. It
fully exploits the attributes of the ABS. After you release the brake pedal, the
function of the Brake Assist is automatically switched off and the brakes operate
in the normal way.
The Brake Assist is part of the ESP system. If a fault occurs in the ESP, the Brake
Assist function is also not available. Further information on the ESP
⇒ page 154.WARNING
● The Brake Assist is also not able to overcome the physical limits of your car
in terms of the braking distance required.
● Adapt your speed to the conditions of the road surface and to the traffic
situation.
● The increased safety offered by the Brake Assist must not tempt you to
take a greater safety risk than otherwise. 
Uphill Start Assist The uphill start assist makes it easier to start off on steep hills. The system assists
a start off by holding the brake pressure produced by the brake pedal actuation
for approx. 2 seconds after releasing the brake pedal. The driver can therefore
move his foot from the brake pedal to the accelerator pedal and start off on the
slope, without having to actuate the handbrake. The brake pressure drops gradu-
ally the more you operate the accelerator pedal. If the vehicle does not start off
within 2 seconds, it starts to roll back.
The uphill start assist is active as of a 5 % slope, if the driver door is closed. It is
always active on slopes when in forward or reverse start off. When driving down-
hill, it is inactive. 
Electromechanical power steering The power steering enables you to steer the vehicle with less physical force.
With the electromechanical power steering, the steering assist is automatically
adapted to the speed and to the steering angle.
It is still possible to fully steer the vehicle if the power steering fails or if the en-
gine is not running (vehicle being towed in). The only difference is that greater
physical effort is required. If there is a fault in the power steering, the warning light
 or  lights up in the
instrument cluster ⇒
 page 24. WARNING
Contact your specialist garage if the power steering is defective. 
Tyre pressure monitoring system Fig. 140 Button for setting the tyre in-
flation pressure control value
The tyre pressure monitoring system compares with the aid of the ABS sensors
the speed and also the rolling circumference of the individual wheels. If the rolling
circumference of a wheel is changed, the warning light
 in the instrument clus-
ter ⇒ page 27 and an acoustic signal sounds.
The rolling circumference of the tyre can change if:
● the tyre inflation pressure is too low,
● the structure of the tyre is damaged,
● the vehicle is loaded on one side,
● the wheels of an axle are loaded heavily (e.g. when towing a trailer or when
driving uphill or downhill),
● snow chains are mounted,
● the temporary spare wheel is mounted,
● one wheel per axle was changed.
Basic setting of the system
After changing the tyre inflation pressures, after changing one or several wheels,
the position of a wheel on the vehicle (e.g. exchanging the wheels between the
axles) or when the warning light lights up while driving, a basic setting of the sys-
tem must be carried out as follows. £ 159

for more than 2
seconds. While pressing the but-
ton, the warning light  lights up. At the same time the memory of the system is
erased and the new calibration is started, which is confirmed with an audible sig-
nal and then the warning light  goes out.
● If the warning light  does not go out after the basic setting, there is a fault in
the system. Have the vehicle inspected by your nearest specialist garage.
Warning light  lights up
If the tyre inflation pressure of at least one wheel is insufficiently inflated in com-
parison to the stored basic value, the warning light  ⇒  lights up.
Warning light  flashes
If the warning light flashes, there is a system fault. Have the vehicle inspected by
your nearest specialist garage. WARNING
● When the warning light  lights up, immediately reduce the speed and
avoid sudden steering and brake manoeuvres. Please stop the vehicle without
delay at the nearest possible stop and inspect the tyres and their inflation
pressures.
● The driver is responsible for the correct tyre inflation pressures. For this
reason, the tyre inflation pressures must be checked regularly.
● Under certain circumstances (e.g. sporty style of driving, wintry or unpaved
roads) the warning light  can be delayed or does not light up at all.
● The tyre pressure monitoring system does not take away the responsibility
from the driver for the correct tyre inflation pressure. Note
The tyre pressure monitoring system:
● does not replace the regular tyre inflation pressure control, because the sys-
tem cannot detect an even pressure loss,
● cannot warn in case of very rapid tyre inflation pressure loss, e.g. in case of
sudden tyre damage. In this case carefully bring the vehicle to a standstill without
sudden steering movements and without sharp braking.
● In order to ensure a proper functioning of the tyre inflation pressure-control
system, it is necessary to carry out the basic setting again every 10 000 km or 1x a
year. Diesel particle filter (diesel engine) In the diesel particle filter the resulting soot particles are collected
and burnt during the combustion of diesel fuel. Fig. 141 Vehicle data sticker
Code 7GG , 7MB or 7MG on the vehicle data sticker, see ⇒ fig. 141 , indicates that
your vehicle is equipped with a diesel particle filter. The vehicle data sticker is lo-
cated on the floor of the luggage compartment and is also stated in the Service
schedule.
The diesel particle filter filters the soot particles completely from the exhaust. The
soot is collected in the diesel particle filter and burnt regularly. To assist this pro-
cedure, we recommend not to drive regularly over short distances.
If the diesel particle filter is full or there is a fault, it is indicated by the warning
light 
. WARNING
● The diesel particle filter achieves very high temperatures. Therefore do not
park at points where the hot filter comes into direct contact with dry grass or
other combustible materials - risk of fire!
● Never use additional underbody protection or corrosion-protection agents
for the exhaust pipes, catalytic converters, diesel particle filter or heat shields.
When the engine reaches its operating temperature, these substances might
ignite - risk of fire. Note
When using diesel fuel with high sulphur content the life of the diesel particle fil-
ter is clearly reduced. A specialist garage will be able to tell you which countries
use only diesel fuel with high sulphur content. 160
Intelligent Technology

–
For vehicles with petrol engine only refuel with unleaded petrol ⇒  page 176,
Unleaded petrol.
– Never run the fuel tank completely empty.
– Do not switch off the ignition while you are driving the vehicle.
– Do not pour too much oil into the engine ⇒
 page 183, Replenishing engine oil.
If you drive your vehicle in a country in which unleaded petrol is not available, you
must have the catalytic converter replaced later when driving the vehicle into a
country in which use of a catalytic converter is mandatory. WARNING
● In view of the high temperatures which may be produced in the catalytic
converter, one should always park a vehicle in such a way that the catalytic
converter cannot come into contact with easily flammable materials below the
vehicle - a risk of fire!
● Never use additional underbody protection or corrosion-protection agents
for the exhaust pipes, catalytic converters or heat shields. Such substances
might ignite when driving - risk of fire! CAUTION
● On vehicles fitted with a catalytic converter, never let the fuel tank run com-
pletely empty. An irregular fuel supply can result in poor ignition or misfiring. Un-
burnt fuel may get into the exhaust system and damage the catalytic converter.
● Filling the tank even only once with leaded petrol will result in the catalytic
converter being destroyed.
● If you detect misfiring, a drop in performance or irregular engine running when
driving, reduce your speed immediately and have the vehicle inspected by the
nearest specialist garage. The symptoms described may be caused by a fault in
the ignition system. Unburnt fuel may get into the exhaust system and damage
the catalytic converter. For the sake of the environment
Even if the exhaust system is operating properly, a sulphur-like exhaust odour
may be produced under certain operating conditions of the engine. This depends
on the sulphur content of the fuel. It is often sufficient to refuel with unleaded
premium-grade petrol of a different brand or at a different filling station. Driving in an economical and environmentally
conscious manner
General Your personal style of driving is a major factor.
Your fuel consumption, any pollution of the environmental and the wear-and-tear
to the engine, brakes and tyres, depend essentially on three factors:
● your personal style of driving,
● the conditions under which your vehicle is operated,
● technical aspects.
You can easily improve your fuel economy by 10 - 15 percent by driving in an eco-
nomical way with foresight. This section is intended to provide you with a number
of tips on how to protect the environment and at the same time save money.
The fuel consumption can naturally also be influenced by factors which are be-
yond the driver's control. It is, for example, normal for the fuel consumption to in-
crease in winter and under worsened conditions such as poor road conditions,
towing a trailer, etc.
The technical requirements for low fuel usage and economic efficiency of the ve-
hicle have already been built into the vehicle at the works. Special attention has
been given to minimising negative effects on the environment. It is necessary to
take note of the guidelines given in this chapter in order to make best use of
these characteristics and to maintain their effectiveness.
The optimal engine speed should be obtained when accelerating, in order to avoid
a high fuel consumption and resonance of the vehicle. 
Looking ahead when driving A vehicle's highest fuel consumption occurs it accelerates.
Avoid accelerating and braking unnecessarily. If you drive with foresight you will
not need to brake so often and will also then not have to accelerate so much. Let
your vehicle coast to a stop, for example, if this is possible, when you see that the
next set of traffic lights is at red. 162
Driving and the Environment

In order to avoid damage to the vehicle when driving through bodies of water (e.g.
flooded roads), observe the following:
●
Determine the depth of the water when driving through bodies of water. The
water can reach at the maximum the web on the lower sill of the vehicle
⇒ fig. 145 .
● Drive no more than at walking speed. At a higher speed, a water wave can
form in front of the vehicle which can cause water to penetrate into the air induc-
tion system of the engine or into other parts of the vehicle.
● Never let the vehicle stand in the water, never drive backwards and do not
switch off the engine. WARNING
● Driving through water, mud, sludge etc. can reduce the braking power and
extend the braking distance - risk of accident!
● Avoid sudden and severe braking manoeuvres immediately after driving
through bodies of water.
● After driving through bodies of water, the brakes must be cleaned and
dried as soon as possible by intermittent braking. Only apply the brakes for
the purpose of drying and cleaning the brake discs if the traffic conditions per-
mit this. Do not place any other road users in jeopardy. CAUTION
● When driving through bodies of water, parts of the vehicle such as the engine,
gearbox, catalytic converter, chassis or electrics can be severely damaged.
● Oncoming vehicles can generate water waves which can exceed the permissi-
ble water level for your vehicle.
● Potholes, mud or rocks can be hidden under the water making it difficult or im-
possible to drive through the body of water.
● Do not drive through salt water. The salt can lead to corrosion. Immediately
rinse all the parts of the vehicle, which came into contact with the salt water, with
fresh water. Note
After driving through a body of water, we recommend that the vehicle is checked
by a specialist garage.  167

Towing a trailer
Technical requirements Your vehicle is designed primarily for transporting persons and luggage. It can,
however, also be used for towing a trailer - provided certain technical equipment
is fitted.
If your vehicle has been
factory-fitted with a towing device or has a towing device
from ŠKODA Original Accessories, then the towing device satisfies all technical
and legal requirements.
Your vehicle is fitted with a 13-pin power socket for the electrical connection be-
tween the vehicle and trailer. If the trailer which you wish to tow has a 7-pin con-
nector, you can use a suitable adapter from
ŠKODA Original Accessories.
This work must be carried out in accordance with the manufacturer's specifica-
tions if a towing device is retrofitted.
Authorised ŠKODA Service Partners can provide detailed information about retro-
fitting a towing device and for any necessary modifications to the cooling system. WARNING
We recommend that you have the towing device from ŠKODA Original Acces-
sories installed by an authorised
ŠKODA Service Partner. He is familiar with all
the relevant details relating to retrofitting such equipment. There is a risk of
an accident if the towing device is not properly fitted! 
General Maintenance Trailer load
The permissible trailer load must on no account be exceeded.
You can negotiate appropriately steeper inclines and descents if you do not make
full use of the permissible trailer load.
The trailer loads specified only apply for
altitudes up to 1000 metres above mean
sea level. The fact that the engine power output drops with increasing height due
to a lowering of air pressure and thus the ability to climb, means that the towed
weight must be reduced by 10 % for every further increase of 1 000 metres in height above sea level. The towed weight is the weight of the (laden) vehicle and
the (laden) trailer together. One should take this into account before driving up to
higher altitudes.
The trailer and drawbar load information on the type plate of the towing device
are merely test data for the towing device The data relating to your vehicle,
which is often less than this test data, can be found in your vehicle registration
documents.
Distribution of the load
Distribute the load in the trailer in such a way that any heavy items are located as
close as possible to the axle. Secure the items to prevent them slipping.
Tyre pressure
Correct the tyre inflation pressure on your vehicle for that of

“fully laden”
⇒  page 192. The inflation pressure of the tyres fitted to the trailer adjust in ac-
cordance with the manufacturer's recommendation.
Exterior mirrors
You have to have additional exterior mirrors fitted if you are not able to see the
traffic behind the trailer with the standard rear-view mirrors. Both exterior mirrors
should be attached to folding arms. Adjust the mirrors so that they provide you
with an adequate field of view to the rear.
Headlights
Before starting off with a hitched trailer, also check the setting of the headlights.
Alter the setting as necessary with the aid of the headlight beam adjuster
⇒  page 49.
Detachable ball head
The ball head is detachable on vehicles with towing device and can be obtained
from ŠKODA Original Accessories. It is stowed together with separate fitting in-
structions in the spare wheel well in the luggage compartment of the vehicle. Note
● We recommend that you also have your vehicle inspected between service in-
tervals if you tow a trailer frequently.
● The handbrake on the towing vehicle must be put on when coupling and de-
coupling the trailer. 168
Towing a trailer

Driving Tips
–
Do not, as far as possible, drive with your vehicle unladen and the trailer laden.
– Do not make full use of the legal maximum speeds. This applies in particular to
downhill sections.
– Apply the brakes in good time.
– Keep a check on the coolant temperature gauge if the outside temperature is
high.
Distribution of weight
The distribution of the weight is very poor if your vehicle is unladen and the trailer
is laden. Maintain a particularly low speed if you cannot avoid driving with this
combination.
Driving speed
Do not drive faster than 80 km/hour for safety reasons. This also applies for coun-
tries in which higher speeds are allowed.
The fact that the driving stability of the vehicle + trailer combination reduces with
increasing speed means that the legally allowed speed should not be used when
there are unfavourable road, weather or wind conditions, particularly near acci-
dent black spots.
You must always reduce your speed immediately as soon as you detect even just
the slightest swaying of the trailer. On no account attempt to stop the trailer
from “swaying”
by accelerating.
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply the
brakes gently at first and then brake firmly. This will avoid brake jolts resulting
from the trailer wheels locking. Shift down gears in good time before negotiating
a downhill section to allow the engine to also act as a brake.
Engine overheating
Please keep a check on the coolant temperature gauge if you have to negotiate a
lengthy slope in a low gear at a high engine speed when the outside temperature
is very high ⇒ page 11, Coolant temperature gauge.
If the needle of the coolant temperature gauge moves into the right-hand area or
even the red area of the scale, reduce your speed immediately. Stop and switch
off the engine if the warning light  in the instrument cluster begins flashing.
Wait a few minutes and check the level of coolant in the coolant expansion bottle
⇒  page 185, Inspecting the coolant level. Please refer to the following guidelines
⇒ page 25, Coolant temperature/ Coolant
quantity .
The coolant temperature can be reduced by switching on the heating.
Any increase in the cooling effect of the coolant fan through shifting down a gear
and increasing the engine speed is not possible since the fan speed is independ-
ent of the engine speed. One should also not drop a gear for this reason when
towing a trailer as long as the engine can manage the slope without any drop in
speed.  169
