BrakesWhat 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. Particul arly 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 conditions
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 coatin g of ice on them in winter. Yo u s h o u l d d r y t h e b r a k e s a s
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 th e bake pads occur if the vehicle has been
parked for a long period an d if you do not make much use of the braking system.
We recommend cleaning the brak e 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 corrosion is
present .
Faults in the brake surface
If you notice that the braking distance ha s 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 garage 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 higher 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 34, “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 jeop-
ardy.

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 other-
wise the braking system could run too hot.

Allow for the fact that new brake pads do not achieve their full braking effi-
ciency until approximately 200 kilometres. New brake pads must be first “run
in” before they develop their optimal fric tion force. You can, however, compen-
sate for this slightly reduced braking fo rce by increasing the pressure on the
brake pedal. This guideline also applie s to any new brake pads installed at a
future date.Caution

Never allow the brakes to rub by applying sl ight pressure if you do not wish to brake
the vehicle. This causes the br akes to overheat and can also result in a longer 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 us e 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 th e ABS, which lasts longer than 1.5 seconds.
After the speed was reduced below 10 km/h or the vehicle was stopped, the brake light
stops flashing and the hazard warning light system switches on. The hazard warning
light system is switched of f automatically after accelerating or driving off again.

Brake boosterThe brake booster boosts the pressure which you generate with the brake pedal. The
necessary pressure is only genera ted 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 phys-
ical effort for braking is required when en gine is switched off. Because if you do
not stop as normal, this can cause an accident and severe injuries.
Antilock brake system (ABS)ABS prevents the wheels locking when braking.General
The ABS contributes significantly to enhanc ing the active safety of your vehicle.
Compared to a vehicle not fitted with the ABS brake system, you are able to retain
optimal steering ability even during a full br ake application on a slippery road surface
because the wheels do not lock up.
You must not expect, however, that the br aking 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 application in this braking
range. Never interrupt the application of the brakes!
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 otherwise -
risk of an accident!

The normal braking system is still fully functional if there is an ABS fault.
Visit a specialist garage as quickly as poss ible and adjust your style of driving to
take account of the ABS fault in the meantime since you will not know the extent
of the fault and in how far the braking efficiency is affected.Note

A warning light comes on if a fault occurs in the ABS system
  page 33.

Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combina-
tion of tyres and wheels) can in fluence the function of the ABS page 214, “Accesso-
ries, changes and replacement of parts”.
Brake Assist*During a severe brake application (e.g. if a hazard exists), the Brake Assist increases the
braking force and thus makes it possible to rapidly produce the pressure required in
the brake system.
The majority of drivers do a pply 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 vehicle to achieve its maximum deceleration and the vehicle covers a greater
distance than necessary.
The Brake Assist is activated by the very qu ick operation of the brake pedal. In such
cases, a much greater braking pressure exists than during a normal brake application.
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 possible time, which
is required for maximum dece leration of the vehicle. You must apply the brake pedal
firmly and hold it in this position in or der to achieve the shortest possible braking
distance.

The Brake Assist is able to help you achieve a shorter braking distance in emergency
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 167.
WARNING

The Brake Assist is also not able to overcome the physical limits of your
vehicle in terms of the braking distance required.

Adapt your speed to the conditions of the road surface and to the traffic situ-
ation.

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 gradually 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 downhill, it is
inactive.Electromechanical power steeringThe power steering enables you to steer the vehicle with le ss 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 engine 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 instru-
ment cluster page 30.
WARNING
Contact your specialist garage if the power steering is defective.Tyre pressure monitoring system*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 circum-
ference of a wheel is changed, the warning light
 lights up in the instrument cluster
 page 33 and an audible 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,

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. exch anging the wheels between the axles) or
when the warning light lights up while drivin g, a basic setting of the system must be
carried out as follows.

Inflate all tyres to the specified inflation pressure page 208.

Switch on the ignition.

Press button  page 172, fig. 151 for more than 2 seconds. While pressing
the button, 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 signal
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 comparison
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 manoeuvr es. Please stop the vehicle without
delay at the nearest possible stop and in spect the tyres and their inflation pres-
sures.

The driver is responsible for the correct tyre inflation pressures. For this
reason, the tyre inflation pressu res 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 inflatio n pressure control, because the system
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 ca refully 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 ba sic setting again every 10 000 km or 1x a
year.
Diesel particle filter* (diesel engine)In the diesel particle filter the resu lting soot particles are collected and
burnt during the combustion of diesel fuel.Code 7GG, 7MB or 7MG on the vehicle data sticker, see fig. 152 , indicates that your
vehicle is equipped with a diesel particle fi lter. The vehicle data sticker is located 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 procedure, we
recommend not to drive regu larly over short distances.

If the diesel particle filter is clogged or there is a fault, it is indicated by the warning light 
.
WARNING

The diesel particle filter achieves very high temp eratures. 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 filter
is clearly reduced. A specialist garage will be able to tell you which countries use only
diesel fuel with high sulphur content.

Catalytic converterProper operation of the emission cont rol system (catalytic converter) is
of major significance for driving your vehicle in an environmentally
conscious way.Please refer to the following guidelines:
– For vehicles with petrol engine only refuel with unleaded petrol  page 192,
“Grades of 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 199, “Replenishing engine oil”.
– Do not tow-start the vehicle over a distance of more than 50 metres page 222,
“Tow-starting and towing vehicle”.
If you drive your vehicle in a country in which unleaded petrol is not available, you
must have the catalytic converter replaced la ter when driving the vehicle into a country
in which use of a catalyti c 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 converte r, never let the fuel tank run completely
empty. An irregular fuel supply can result in poor ignition or misfiring. Unburnt fuel
may get into the exhaust system an d damage the catalytic converter.

Filling the tank even only once with le aded petrol will result in the catalytic
converter being destroyed.

If you detect misfir ing, 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 ma y 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 pr operly, a sulphur-like exhaust odour may be
produced under certain oper ating 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 mannerGeneral
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 econom-
ical 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 beyond the
driver's control. It is, for example, normal for the fuel consumption to increase in
winter and under worsened cond itions such as poor road conditions, towing a trailer,
etc.
The technical requirements for low fuel usage and economic efficiency of the vehicle
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

Technical Data
Driving through bodies of water on roadsIn order to avoid damage to the vehicle wh en driving through bodies of water (e.g.
flooded roads), observe the following:
Determine the depth of the water when driv ing through bodies of water. The water
can reach at the maximum the web on the lower sill of the vehicle fig. 156 .

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 induction 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 permit
this. Do not place any other road users in jeopardy.
Caution

When driving through bodies of water, pa rts 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 permissible
water level for your vehicle.

Potholes, mud or rocks can be hidden under the water making it difficult or impos-
sible 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.

Towing a trailer
182
Towing a trailerTo w i n g a t r a i l e rTechnical requirements
The towing device must satisfy certain technical requirements.Your vehicle is designed primarily for tr ansporting persons and luggage. It can,
however, also be used for towing a traile r - provided certain technical equipment is
fitted.
If your vehicle has already been supplied with a factory-fitted towing device then
everything that is nece ssary for towing a trailer in technical terms, and in terms of the
law, has already been taken into account.
Your vehicle is fitted with a 13-pin power socket for the electrical connection between
the vehicle and trailer. If the tr ailer which you wish to tow has a 7-pin connector, you
can use a suitable adapter
16) from Škoda original accessories.
This work must be carried out in accordance with the manufacturer's specifications if
a towing device is retrofitted.
Authorised Škoda Service Partners are familiar with details relating to retrofitting a
towing device and for any necessary modifications to the cooling system.
WARNING
We recommend that you have the towing device from Škoda original accesso-
ries 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
There are a number of points to pay attention to when towing a trailer.Trailer load
The permissible trailer load must on no account be exceeded.
You can negotiate appropriately steeper inclin es and descents if you do not make full
use of the permissible trailer load.
The trailer loads specified only apply for altitudes up to 1 000 metres above mean sea
level. The fact that the engi ne power output drops with increasing height due to a
lowering of air pressure and thus the abil ity 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 docu-
ments.
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 th e items to prevent them slipping.
Tyre inflation pressure
Select the tyre inflation pressure on yo ur vehicle for that of “fully laden”, page 208.
The inflation pressure of the tyres fitted to the trailer adjust in accordance with the
manufacturer's recommendation.
Exterior mirrors
You have to have additional ex terior 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.
16)In some countries the adapter is supplied with the towing device.s43s.1.book Page 182 Thursday, May 13, 2010 1:21 PM
