fied. 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 35.
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 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 use
of the braking power of the vehicle and reduces the strain on the brakes.
Any additional braking should be done intermittently, not continuously.
Antiblock 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 optimal 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
As soon as the vehicle speed has increased to about 6 km/hour an auto-
matic test procedure is conducted during which you will be able to hear a
pumping noise for about 1 second.
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
•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 otherwise the braking system could run too
hot.
•Allow for the fact that new brake pads do not achieve their full
braking efficiency until approximately 200 kilometres. New brake
pads must be first “run in” before they develop their optimal fric-
tion 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.

Note
•A warning light comes on if a fault occurs in the ABS system
⇒ page 34.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other
assignment of tyres and wheels) can influence the function of the ABS
⇒ page 226.
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 apply the brakes in good time in dangerous situ-
ations, but do not depress the brake pedal with sufficient pressure. Conse-
quently, 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 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
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.
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 169.
Power steering
Power steering assists the driver in steering the vehicle and reduces the
physical force needed for steering.
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 Skoda dealer as quickly as possible and adjust
your style of driving to take account of the ABS fault in the mean-
time since you will not know how great the damage is.
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.

Tyre inflation pressure
Select the tyre inflation pressure on your vehicle for that of “fully laden”,
⇒
page 220. 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 exterior mirrors fitted if you are not able to see
the traffic behind the trailer with the standard rear-view mirrors. Both exte-
rior 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 head-
lights. Alter the setting as necessary with the aid of the headlight beam
adjuster ⇒page 58.
Detachable ball head
The ball rod is detachable on vehicles which feature a factory-fitted towing
device. It is stowed together with separate fitting instructions in the spare
wheel well in the luggage compartment of the vehicle.
Further information on the towing device ⇒page 186.
Note
•We recommend that you also have your vehicle inspected between
service intervals if you tow a trailer frequently.
•The handbrake on the towing vehicle must be put on when coupling
and decoupling the trailer.
Driving Tips
Particular caution is required when towing a trailer.
– 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 countries 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 accident 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, 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 downhill stretch in a low gear at a high engine speed
when the outside temperature is very high ⇒page 14. 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 208.
Please refer to the following guidelines ⇒page 31.
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 independent 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.
Detachable towing device*
The detachable ball head of the towing device is stowed in the spare
wheel well in the luggage compartment.
An instruction for correct installation and removal of the ball head of the
towing device is supplied with the ball head
Note
•Do not carry out any modifications or repairs to the ball head or to any
other components on the towing device.
WARNING
•Do not use any aids or tools for installing or removing the ball
head. This might result in damage to the locking mechanism to the
extent that the safety of the towing device is no longer assured -
risk of an accident.

Care and cleaning
190
Automatic vehicle wash systems
The paintwork of the vehicle is sufficiently resistant that the vehicle can be
washed normally in automatic vehicle wash plants without any problem.
The actual stress to which the paintwork is subjected, however, depends
greatly on the design of the vehicle wash system, the filtering of the water
and the type of washing and care products used. If the paintwork of your
vehicle appears mat after being washed or even has scratches, point this
out to the operator of the vehicle wash plant. Use a different vehicle wash
plant, if necessary.
There are no particular points to note before washing your vehicle in such
a plant other than the usual precautionary measures (closing windows
and sliding/tilting roof, moving any factory-fitted aerials down flat against
the bodywork, etc.).
If you have any particular attached parts fitted to your car - such as spoiler,
roof rack system, two-way radio aerial - it is best to first of all consult the
operator of the car wash plant.
It is important to degrease the lips of the windscreen wiper rubbers after
passing through the automatic vehicle wash system.
Caution
Do not screw the swivelling down roof aerial tight before washing the
vehicle in an automatic vehicle wash system - risk of damage!
Washing vehicle by hand
It is important to first soften the dirt with plenty of water and rinse it off as
thoroughly as possible before washing your vehicle by hand.
One should then clean the vehicle using a soft washing sponge,
washing glove or a washing brush and only slight pressure. Work from
the top to the bottom - beginning with the roof. Only place slight pressure
on the vehicle paintwork during cleaning Only use a shampoo for stub-
born dirt.
Wash out the sponge or washing glove thoroughly at short intervals.
Clean wheels, door sills and similar parts last. Use a second sponge for
such areas.
Rinse off the vehicle well after giving it a wash and dry it off using a
chamois leather.
Caution
•Do not wash your vehicle in bright sunlight - risk of paint damage.
•Ensure that the jet of water is not aimed directly at the locks or at the
door and panel joints if you spray your vehicle in winter down with a hose
- risk of freezing.
•Do not use any insect sponges, rough kitchen sponges or similar
cleaning products - risk of damage to the surface of paintwork.
WARNING
When washing your vehicle in the winter: Water and ice in the
brake system can affect the braking efficiency - risk of accident.
WARNING
•The ignition should always be switched off when you wash your
vehicle - risk of accident!
•Protect your hands and arms from sharp-edged metal parts
when you are cleaning the underfloor, the inside of the wheel hous-
ings or the wheel trims - risk of cuts.

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.
Locks
We recommend that you use Genuine Škoda Spray with regreasing and
anticorrosive effect for de-icing locks.
Note
When washing your vehicle, ensure that as little water as possible gets
into the locks.
Wheels
Steel wheels
You should also thoroughly wash the wheels and wheel trims when giving
your vehicle its regular wash. This prevents any brake dust, dirt and road
salt from sticking to the wheel hubs. You can remove stubborn brake abra-
sion adhering to the wheels with an industrial cleaner. Touch up any
damage to the paintwork on the wheels before rust is able to form.
Light alloy wheels
Regular care of light alloy wheels is necessary in order to retain their
decorative appearance over long periods. It is particularly important to
remove any road salt and brake abrasion from light alloy wheels every two
weeks, otherwise the surface will suffer. Wash thoroughly and then treat
the wheels with a protective product for light alloy wheels which does not
contain any acidic components. You should provide the wheel hubs with
a hard wax layer every three months. You must not use any products
which cause abrasion when treating the wheel hubs. Any damage to the
paint layer on the wheel hubs must be touched up immediately.
We recommend using a preservative from the range of accessories
offered by your Skoda dealer.
Note
Severe layers of dirt on the wheels can also result in wheel imbalance.
This may show itself in the form of wheel vibration which is transmitted to
the steering wheel which, in certain circumstances, can cause premature
wear of the steering. It is therefore important to clean dirty wheels.
Underbody protection
The underside of your vehicle is protected for life against chemical and
mechanical influences.
One cannot, however, completely rule out damage to the
protective layer
when driving so we recommend that you inspect the protective layer on
the underside of your vehicle and on the chassis at certain intervals - this
is best done at the beginning and end of the winter - and to touch up any
damaged areas.
Škoda dealers have suitable spray products available as well as the
necessary equipment and are familiar with the instructions for its use. It is
therefore best to have such touch-up work or additional corrosion protec-
tion measures carried out by a Škoda dealer.
WARNING
One should remember when cleaning the wheels that moisture, ice
and road salt may adversely affect braking efficiency - risk of an
accident!

General comments
•New tyres do not offer optimal grip at first and should therefore be run
in for about 500 km at a moderate speed and an appropriately cautious
style of driving. You will also profit from longer tyre life.
•The tread depth of new tyres may differ because of design features
and the configuration of the tread (depending on the type of tyre and the
manufacturer).
•Drive over curbs on the side of the road and other such obstacles
slowly and, where possible, at a right angles in order to avoid damage to
tyres and wheel trims.
•Inspect your tyres from time to time for damage (punctures, cuts, splits
and bulges). Remove foreign bodies from the tyre profile.
•Damage to tyres and wheels is frequently not visible. Unusual vibra-
tions or pulling of the vehicle to one side could be a sign of tyre damage.
Please reduce your speed immediately and stop if you suspect that
a wheel is damaged. Inspect the tyres for signs of damage (bulges,
splits, etc.) If no visible damage is present, please drive at an appropri-
ately slow speed and carefully to the nearest Škoda dealer in order to
have your vehicle inspected.
•Also protect your tyres from contact with oil, grease and fuel.
•Immediately replace any dust caps of the valves which have got lost.
•Mark wheels before removing them so that their previous direction of
running can be maintained when mounted them again.
•Always store wheels or tyres which been removed in a cool, dry and,
where possible, dark place. Tyres which are not fixed to a wheel trim
should be stored upright. Please comply with any national regulations in other countries which may
differ from the information stated above.
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.
Further information concerning the use of unidirectional tyres
⇒
page 225.
Note
Please observe the various differing legal requirements regarding tyres.

Tyre life
The life of your tyres very much depends on the following points: Tyre inflation pressure
The working life of tyres will be shortened considerably if the tyres are
insufficiently or over-inflated and this will have an adverse effect on the
handling of your vehicle.
Check the inflation pressure of the tyres at least once a month. The tyre
inflation pressures for
summer tyres are indicated on the inside of the
fuel filler flap ⇒fig. 164 . The inflation pressures for winter tyres are 0.2
bar higher than those for summer tyres ⇒page 224.
Correctly inflated tyres are of particular importance when travelling at high
speeds. It is therefore good to check the pressure at least once a month
and also before setting off on a long trip. Please do not forget the spare
wheel when checking the tyres.
The tyre pressure should be at the highest pressure specified for your
vehicle at all times.
On cars with full wheel trim, valve extensions are fitted in place of dust
caps ⇒fig. 165 . It is not necessary to unscrew the valve extensions in
order to check and alter the inflation pressure of the tyre.
Driving style
Fast cornering, sharp acceleration and braking (squealing tyres) increase
wear-and-tear on your tyres.
Balancing wheels
The wheels of a new vehicle are balanced. There are a wide range of influ-
ences when driving which may result in an imbalance and which makes
themselves felt through vibration in the steering.
You should have the wheels rebalanced since any imbalance increases
wear-and-tear on the steering, the suspension and tyres. A wheel must
also be rebalanced when a new tyre is fitted and each time a tyre is
repaired.

Wheel alignment errors
Incorrect wheel alignment at the front and rear will not only increase wear-
and-tear on the tyres but will also has an adverse effect on vehicle safety.
Contact your Škoda dealer if you notice any unusual tyre wear.
For the sake of
the environment
Tyres which are insufficiently inflated increase your fuel consumption.
Wear indicators
The base of the tread of the original tyres has wear indicators 1.6 mm
high, installed at right angles to the direction of travel. These wear indica-
tors are located at 6 to 8 points depending on the make and are evenly
spaced around the circumference of the tyre ⇒fig. 166 . Markings on the
walls of the tyres through the letters “TWI” or triangular symbols identify
the position of the wear indicators.
A remaining tread of just 1.6 mm, measured in the grooves of the tread
next to the wear indicators, means that your tyres have reached their
legally permissible minimum tread depth.
WARNING
If the inflation pressure is too low, the tyre must perform a greater
flexing work. At higher speeds the tyre will warm up as a result of
this. This can result in tread separation and even a tyre blowout.
Fig. 166 Tyre tread
with wear indicators
WARNING
•You must have your tyres replaced with new ones at the latest
when the wear indicators have been worn down. The legally
permissible minimum tread de pth should be observed.
•Worn tyres do not provide the necessary adhesion to the road
surface at high speeds on wet roads. One could experience “aqua-
planing” (uncontrolled movements of the vehicle - “swimming” on
a wet road surface).

Wheels and Tyres
222
Changing wheels around
If significantly greater wear is present on the front tyres, we recommend
changing the front wheels around with the rear wheels as shown in the
diagram ⇒fig. 167 . You will then obtain approximately the same life for
all the tyres.
It may be advantageous to swap the tyres over “crosswise” when certain
types of wear characteristic arise on the running surface of the tyres (but
not in the case of unidirectional tyres). Škoda dealers can provide you with
details.
We recommend that you change the wheels around every 10 000 km in
order to achieve even wear on all wheels and to obtain optimal tyre life.
New tyres and wheels
Tyres and wheel rims are important design elements. One should there-
fore use the tyres and wheel rims which have been released for use by Škoda Auto. They are exactly matched to the vehicle type and therefore
contribute significantly to good road holding and safe driving characteris-
tics
⇒ .
Only fit radial tyres of the same type on all 4 wheels of the same type, size
(rolling circumference) and, if possible, the same tread pattern.
Škoda dealers have access to the most current information about which
tyres we have released for use.
We recommend that you have any work relating to tyres or wheels carried
out by your Škoda dealer . Your dealer has all of the necessary special
tools and replacement parts available plus the required specialist knowl-
edge and is also in a position to properly dispose of the old tyres. A large
number of Škoda dealers also have an attractive range of tyres and
wheels available.
The tyre/wheel combinations which are approved for your vehicle are indi-
cated in your vehicle documents. Approval and licensing may differ
according to the legislation prevailing in individual countries.
Proper knowledge of the tyre data makes it easier for you to select the
correct type of tyre. Radial tyres have, for example, the following inscrip-
tion :
205 / 60 R 15 91 V
