Driving TipsIntelligent TechnologyElectronic stability programme (ESP)*GeneralGeneral
The ESP aids you maintain control of your vehicle in situations in borderline driving
situations such as when negotiating a curve too fast. The risk of skidding is reduced
and your vehicle thus offers greater driving stability depending on the conditions of
the road surface. This occurs at all speeds.
The following systems are integrated into the electronic stability programme:•
Electronic Differential Lock (EDL);
•
Traction control system (TCS);
•
Antilock brake system (ABS);
•
Brake Assist.Operating principle
The ESP switches on automatically when the engine is started and then conducts a
self-test. The ESP control unit processes data from the individual systems. It also
processes additional measurement data which are supplied by highly sensitive
sensors: the rotational velocity of the vehicle about its vertical axis, the lateral accel-
eration of the vehicle, the braking pressure and the steering angle.
The direction which the driver wishes to take is determined based on the steering
angle and the speed of the vehicle and is constantly compared with the actual
behaviour of the vehicle. If differences exist, such as the vehicle beginning to skid,
the ESP will automatically brake the appropriate wheel.
The car is stabilised again by the forces which take effect when the wheel is braked.
Intervention into the brake system takes place primarily on the outer front wheel of
a vehicle which tends to oversteer (tendency for the rear of the vehicle to break
away) while occurs this is on the inner rear wheel of a vehicle which tends to under-
steer (tendency to shift out of the curve). This braking control cycle is accompanied
by noises.
The ESP operates in combination with the ABS ⇒page 159, “Antilock brake system
(ABS)*”. If there is a fault in the ABS system, the ESP also does not operate.
The ESP warning light lights up in the instrument cluster when there is a fault on the
ESP
 ⇒page 35.
Switching off
You can switch the ESP off and on again as you wish, by pressing the button
⇒fig. 165. The ESP warning light lights up in the instrument cluster when the ESP is
switched off
 ⇒page 35.
The ESP should normally always be switched on. It may be good practice in certain
exceptional cases, such as when you wish to have wheel slip, to switch off the
system.

when driving with snow chains;
•
when driving in deep snow or on a loose surface;
•
when it is necessary to rock a vehicle when it has become stuck.
then you should switch on the ESP again.
WARNING
It is also not possible for the ESP to overcome the physical limits of the
vehicle. Even if a vehicle fitted with ESP you should still always adapt your
style of driving to the condition of the road surface and the traffic situation.
This particularly applies when driving on slippery and wet roads. The
increased safety offered must not tempt you to take greater risks than other-
wise - risk of an accident!
Note
•
All four wheels must be fitted with the same tyres in order to achieve problem-
free operation of the ESP. Differing rolling circumferences of the tyres can lead to an
undesirable reduction in the engine output.
•
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 ESP ⇒page 204,
“Accessories, changes and replacement of parts”.
Traction control system (TCS)*
The traction control system prevents the driven wheels from spinning
when accelerating.General
The TCS makes it much easier, and sometimes at all possible, to start off, accelerate
and climb a steep hill when the conditions of the road surface are unfavourable.
Operating principle
The TCS switches on automatically when the engine is started and then conducts a
self-test. The system monitors the speeds of the driven wheels with the aid of the
ABS sensors. If the wheels are spinning, the force transmitted to the road surface is
automatically adapted by reducing the engine speed. This occurs at all speeds.
The TCS operates in combination with the ABS ⇒page 159, “Antilock brake system
(ABS)*”. The TCS will not function if a fault exists in the ABS system.
The TCS warning light lights up in the instrument cluster when there is a fault on the
TCS
 ⇒page 34.
Switching off
You can switch the TCS off and on again as you wish by pressing the button
⇒fig. 166. The TCS warning light lights up in the instrument cluster when the TCS is
switched off

“Accessories, changes and replacement of parts”.
Electronic Differential Lock (EDL)*
The electronic differential lock prevents an individual wheel from
slipping.Models fitted with ESP are equipped with electronic differential lock (EDL).
General
The EDL makes it much easier, and sometimes at all possible, to start off, accelerate
and climb a steep hill when the conditions of the road surface are unfavourable.Operating principle
The EDL is activated automatically, that is without any action on the part of the
driver. It monitors the speeds of the driven wheels with the aid of the ABS sensors.
Should only one drive wheel begin spinning on a slippery surface there will be an
appreciable difference in the speed of the driven wheels. The EDL function brakes
the slipping wheel and the differential transmits a greater driving force to the other
driven wheel. This control process is also accompanied by noises.
Overheating of the brakes
The EDL switches off automatically if unusually severe stresses exist in order to
avoid excessive heat generation in the disc brake on the wheel which is being
braked. The vehicle can continue to be driven and has the same characteristics as a
vehicle not fitted with EDL.
The EDL switches on again automatically as soon as the brake has cooled down.
WARNING
•
Carefully depress the accelerator when accelerating on uniformly slip-
pery road surfaces, such as ice and snow. The driven wheels might still spin
despite the EDL and affect the stability of the vehicle - risk of an accident!
•
You should always adapt your style of driving to the condition of road
surface and to the traffic situation even when your vehicle is fitted with EDL.
The increased safety offered must not tempt you to take greater risks than
otherwise - risk of an accident!Note
•
If the ABS or TCS or ESP warning light comes on, this may also indicate a fault in
the EDL. Please have the vehicle inspected as soon as possible by a specialist
garage.
•
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 EDL ⇒page 204,
“Accessories, changes and replacement of parts”.

Intelligent Technology 160brake pedal firmly and hold it in this position in order 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 155.
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
situation.
•
The increased safety offered by the Brake Assist must not tempt you to
take a greater safety risk than otherwise.
Electrohydraulic power steeringThe power steering enables you to steer the vehicle with less physical force.
The steering characteristics can be changed by a specialist garage.
You will place great stresses on the power steering system if the steering is turned
to full lock when the vehicle is stationary. Turning the steering to full lock in such a
situation will be accompanied by noises.
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.
It is possible that the hydraulic pump of the power steering will not run due to the
low vehicle network voltage if the battery has gone flat and the engine must started
with the help off jump leads. This condition will be indicated by lighting up of the
warning light.The power steering operates again if the battery is charged to a specific range when
engine is running. It also operates again, if the engine can be started with its own
battery.
If there is a fault in the power steering, the warning light lights up in the instrument
cluster
 ⇒page 29.
Caution
Do not leave the steering at full lock for more than 15 seconds when the engine is
running - risk of damaging the power steering!
Note
Have the steering inspected as soon as possible by a specialist garage if there is a
leak or fault in the system.Tyre inflation pressure-control system*The tyre inflation pressure-control system compares with the aid of the ABS sensors
the speed and also the rolling circumference of the individual wheels. If the tyre
inflation pressure is significantly changed and thus the rolling circumference of a
wheel, the warning light
 lights up in the instrument cluster ⇒page 35. The tyre
inflation pressure-control system functions late or too sensitively if:

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.
Function description
After the basic setting of the system the “adaptation” of the tyre inflation pressures
and then the tyre pressure control in the individual tyres are performed.
Warning light

If the tyre inflation pressure of at least one wheel is insufficiently inflated in compar-
ison to the stored basic value, the warning light
 ⇒ lights up. Inflate all tyres
to the specified inflation pressure ⇒page 198, “Tyre life” and then perform a basic
setting of the system.
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 inflation pressure-control system does not take away the
responsability from the driver for the correct tyre inflation pressure.Note
The tyre inflation pressure-control system:•
does not replace the regular tyre inflation 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 carefully bring the vehicle to a standstill without
sudden steering movements and without sharp braking.

Taking care of your vehicle and cleaning the vehicle 176Plastic partsExternal plastic parts are cleaned by normal washing. Plastic parts and synthetic
leather can also be treated with special solvent-free plastic cleaning agents if a
damp cloth is not sufficient. Paint care products are not suitable for plastic parts.
Caution
Solvent-free cleaners attack the material and can damage it.WindowsOnly use a plastic ice scraper for removing snow and ice from the windows and
mirrors. You should not move the ice scraper forward and backward but in one
direction on the window which you are cleaning in order to avoid any damage to
the surface of the glass.
You can best remove residues of rubber, oil, grease, wax or silicone by using a
special window cleaner or a special silicone remover.
You should also clean the windows regularly from the inside.
Do not use window leathers which you have used to polish the vehicle body to dry
off the windows. Residues of preservatives in the window leather can dirty the
window and reduce visibility.
Do not affix any stickers over the inside of the rear window to avoid damage to the
heating elements of the rear window heater.
We recommend using a preservative from Škoda genuine accessories offered by
your Škoda dealer.
Caution
•
Never remove snow or ice from the glass parts with warm or hot water - risk of
formation of cracks in the glass!
•
When removing snow or ice from the windows and mirror lenses make sure not
to damage the paintwork of the vehicle.
The headlight lensesPlease do not use any aggressive cleaning or chemical solvent products for cleaning
the front headlights - risk of damage to the plastic lenses. Please use soap and
clean warm water.
Caution
Never wipe the headlights dry and do not use any sharp objects for cleaning the
plastic lenses, this may result in damage to the protective paintwork and conse-
quently in formation of cracks on the headlight lenses, e.g through effect of chem-
ical products.Door and window sealsThe rubber seals on the doors, boot lid, bonnet and windows remain supple and
last longer if you treat them from time to time with a rubber care product (e.g. with
a spray with silicone-free oil). You also avoid premature wear of the seals and
prevent leakages in this way. It is also easier to open the doors. Rubber seals which
are well cared for also do not stick together in cold winter weather.Locking cylinderWe recommend that you use the spray from Škoda original accessories with
regreasing and anticorrosive effect for de-icing locking cylinders.
Note
When washing your vehicle, ensure that as little water as possible gets into the
locking cylinders.

Fuel 182Operation in winterWinter-grade diesel fuel
A different grade of diesel fuel is available at filling stations in winter than during the
summer. Using “summer-grade diesel fuel” at temperatures below 0°C can result in
operational problems because the diesel becomes viscous as a result of paraffin
separation.
It is therefore the case that EN 590 prescribes diesel fuel class for certain periods of
the year which can also be purchased at the corresponding time during the year.
“Winter-grade diesel fuel” will still operate properly even at a temperature of -20°C.
It is often the case in countries with different climatic conditions that diesel fuels
available have a different temperature characteristic. The specialist garages and the
filling stations in the country concerned will be able to provide you with informa-
tion regarding the diesel fuels available.
Prewarming fuel
The vehicle is fitted with a fuel filter prewarming system. This secures operation of
a vehicle using diesel fuel down to an environmental temperature of -25°C.
Caution
It is not permitted to add the various fuel additives on the market, including petrol,
to diesel fuel in order to improve its flow properties.
RefuellingOpen fuel filler flap
– Open the fuel filler flap with the hand.
– Unlock the fuel filler cap on the fuel filler tube to the left using the
vehicle key.
– Unscrew the fuel filler cap anti-clockwise and place the fuel filler cap
from above on the fuel filler flap ⇒fig. 173.
Closing fuel filler cap
– Screw on the cap by turning it to the right until it is heard to lock.

Wheels and Tyres 202Winter tyresThe handling of your vehicle will be significantly improved when driving on wintry
roads if you fit winter tyres. Summer tyres do not offer the same grip on ice, snow
and at temperatures below 7 °C because of their construction (width, rubber blend,
tread pattern). This applies in particular to vehicles which are equipped with low-
profile tyres or high-speed tyres (code index H, V or W on wall of tyre).
Winter tyres must be mounted on all four wheels to obtain the best handling char-
acteristics.
You must only fit those types of winter tyre which are approved for your vehicle. The
permissible sizes of winter tyres are stated in your vehicle documents. Approvals
may differ because of national legislation.
Please remember that the tyres should be inflated to 20 kPa (0.2 bar) more than is
the case for summer tyres ⇒page 198.
Winter tyres no longer offer the same winter performance once the tyre tread has
worn down to a depth of about 4 mm.
Ageing a l s o c a u s e s w i n t e r t y re s t o l o s e m o s t of their winter performance properties
- even in cases where the remaining tread depth is still clearly more than 4 mm.
Speed restrictions apply to winter tyres as well as to summer tyres ⇒page 200,
⇒.
You can fit winter tyres of a lower speed category to your vehicle provided that you
also do not drive faster than the permissible maximum speed for such tyres, even
if the possible maximum speed of your vehicle is higher. The corresponding tyre
category can damage the tyres when exceeding the permissible maximum speed.
Please pay attention to the notes if you decide to fit winter tyres ⇒page 198.
You can also fit so-called “all-year tyres” instead of winter tyres.
Please contact your specialist garage if there are any points which are not clear who
will be able to provide you with information regarding the maximum speed for your
tyres.
WARNING
You must on no account drive your car at more than the permissible
maximum speed for your winter tyres - risk of an accident resulting from
tyre damage and loss of control over your car.
For the sake of the environment
Fit your summer tyres on again in good time since summer tyres offer you better
grip and handling on roads which are free of snow and ice as well as ar tempera-
tures below 7 °C - the braking distance is shorter, there is less tyre noise, tyre wear
is reduced and fuel consumption is reduced.
Note
Please observe the various differing legal requirements regarding tyres.Unidirectional tyres*The direction of rotation of the tyres is marked by arrows on the wall of the tyre.
This indicates the direction of rotation of the tyre, and it is essential that the tyres
are fitted on to run in this direction. Only then are the tyres able to provide the
optimal properties in terms of grip, low noise, wear-and-tear and aquaplaning.
Should it be necessary to fit on a spare wheel in exceptional cases with a tyre not
dedicated to the running direction or in opposite running direction, please adopt a
cautious style of driving as the tyre is no longer able to provide optimal grip and
handling in such a situation. This particularly important on wet roads. Please refer
to the notes ⇒page 208, “Spare wheel*”.
You should have the defective tyre replaced as soon as possible and restore the
correct direction of rotation on all tyresSnow chainsSnow chains must only be mounted on the front wheels.
