111WARNING■ A lack of fuel can cause irregular engine running or cause the engine to shut
down. The brake assist systems would then fail to function – risk of accident!■
Adjust the speed and driving style to the current visibility, weather, road and
traffic conditions. The increased safety provided by the brake assist systems
must not tempt you to take safety risks – risk of accident!
■
In the event of an ABS fault, visit a specialist garage immediately. Adjust
your style of driving according to the damage to the ABS, as you will not know
the exact extent of the damage or the extent to which this is limiting the
braking efficiency.
CAUTION
■ All four wheels must be fitted with the same tyres approved by the manufactur-
er to ensure the brake assist systems operate correctly.■
Changes to the vehicle (e.g. to the engine, brakes, chassis) can influence the
functionality of the brake assist systems » page 146, Services, modifications and
technical alterations .
■
If a fault occurs in the ABS system, the ESC, TCS and EDL will also fail to work.
An ABS fault is indicated with the warning light  » page 24 .

Electronic Stability Control (ESC)
First read and observe the introductory information and safety warn-
ings
on page 110.
The ESC system helps improve control of the vehicle in situations where it is be-
ing operated at its dynamic limits, such as a sudden change to the direction of
travel. Depending on the road surface conditions, the risk of skidding is reduced,
thereby improving the vehicle's driving stability .
The ESC system is automatically activated each time the ignition is switched on.
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. In the event of deviations, such as the car beginning to
skid, the ESC system will automatically brake the appropriate wheel.
During an intervention of the system, the warning light 
flashes in the instru-
ment cluster.
The following systems are integrated into the electronic stabilisation control
(ESC) :
› Antilock brake system (ABS),
› Traction control (TCS),
› Electronic Differential Lock (EDL)
› Hydraulic Brake Assist (HBA)
› Hill Hold Control (HHC).
The ESC system cannot be deactivated. The 
» Fig. 99 on page 111 button can
only be used to deactivate the TCS. The 
warning light comes on in the instru-
ment cluster when the TCS is deactivated.
In the event of an ESC fault, the ESC warning light illuminates in the instrumentcluster 
» page 23 .
Hydraulic Brake Assist (HBA)
HBA increases the braking effect and helps to shorten the braking distance.
The HBA is activated by very quick operation of the brake pedal. In order to ach-
ieve the shortest possible braking distance, the brake pedal must be applied firm-
ly until the vehicle has come to a standstill.
The HBA function is automatically switched off when the brake pedal is released. The ABS is activated faster and more effectively with the intervention of the HBA. 

WARNINGObserve the following instructions for the proper use of the seat belts.■Never use one seat belt to secure two persons (including children). The
seatbelt must not be placed over a child who is sitting on the lap of another
passenger.■
The lock tongue should only be inserted into the lock which is the correct
one for your seat. Wrong use of the safety belt will reduce its capacity to pro-
tect and the risk of injury increases.
■
The slot of the belt tongue must not be blocked, otherwise the belt tongue
will not lock in place properly.
■
Many layers of clothing and loose clothing (e. g. a winter coat over a jacket)
do not allow you to be correctly seated and impairs proper operation of the
seat belts.
■
It is prohibited to use clamps or other objects to adjust seat belts (e. g. for
shortening the belts for smaller persons).
■
The seat belts for the rear seats can only fulfil their function reliably when
the seat backrests are correctly locked into position » page 55.
WARNINGObserve the following instructions for proper maintenance of the seat belts.■The belt webbing must always be kept clean. Soiled belt webbing may im-
pair proper operation of the inertia reel » page 156.■
The seat belts must not be removed or changed in any way. Do not attempt
to repair the seat belts yourself.
■
Check the condition of all the seat belts on a regular basis. If any damage to
the seat belts, seat belt connections, inertia reel or the lock is detected, the
relevant seat belt must be replaced by a specialist garage.
■
Damaged seat belts which have been subjected to stress in an accident and
were therefore stretched, must be replaced - this is best done by a specialist
garage. The anchorage points of the belts must also be inspected. The an-
chorage points for the belts should also be checked.
Note
The national legal requirements must be observed when using seat belts.
The physical principle of a frontal collisionFig. 111
Driver without a fastened seat belt/rear passenger without a fas-
tened seat belt
First read and observe the introductory information and safety warn-ings
on page 127.
As soon as the vehicle is moving, so-called kinetic energy (the energy of motion)
is produced both in terms of the car as well as in terms of the occupants.
The magnitude of this kinetic energy depends essentially on the speed at which
the vehicle is travelling and on the weight of the vehicle including the occupants.
The greater the speed and weight increase, the greater the amount of energy
which has to be absorbed in the event of an accident.
The speed of the vehicle is the most important factor. Doubling the speed of the
vehicle from 25 km/h up to 50 km/hour increases the kinetic energy four times.
The idea that it is possible to support your body with your hands in a minor acci- dent is incorrect. Even in a collision at only a low speed, the forces acting on the
body are such that it is no longer possible to support your body.
Even if you only drive at a speed of 30-50 km/h, the forces that your body is ex-
posed to in the event of an accident can exceed a metric ton (1000 kg).
For example, a person's weight of 80 kg “increases” to 4.8 tons (4800 kg) at
50 km/h.
In the event of a frontal collision, occupants of the car not wearing a seat belt are thrown forward in an uncontrolled way and strike parts of the interior of the car,
such as the steering wheel, dash panel or windscreen » Fig. 111 - 
. In certain cir-
cumstances you could even be thrown out of the vehicle, which could cause life threatening or even fatal injuries. 

178WARNING■ The national legal regulations must be observed for the use of tyres.■Observe the national legal regulations relating to the use of snow chains
and the maximum vehicle speed with snow chains.WARNINGThe following instructions for the use of tyres must be observed.■For the first 500 km, new tyres do not yet provide optimum grip, and appro-
priate care should therefore be taken when driving – risk of accident!■
Only use radial tyres of the same type, size (rolling circumference) and tread
pattern on all four wheels.
■
For reasons of driving safety, do not replace tyres individually.
■
Never exceed the maximum permissible load bearing capacity for fitted
tyres – risk of accident!
■
Never exceed the maximum permissible speed for fitted tyres – risk of acci-
dent!
WARNING (Continued)■ Incorrect wheel alignment at the front or rear impairs handling – risk of acci-
dent!■
Unusual vibrations or pulling of the vehicle to one side could be a sign of
tyre damage. If there is any doubt that a wheel is damaged, immediately re-
duce your speed and stop! If no external damage is evident, drive slowly and
carefully to the nearest specialist garage to have the vehicle checked.
■
Only use tyres or wheel rims that have been approved by ŠKODA for your
model of vehicle. Failure to observe this instruction may impair the road safety
of your vehicle – risk of accident!
WARNINGObserve the following information regarding tyre damage and wear.■Never use tyres if you do not know anything about the condition and age.■
Never drive with damaged tyres – risk of accident!
■
Immediately replace damaged wheel rims or tyres.
■
You must have your tyres replaced with new ones at the latest when the
wear indicators have been worn down.
■
Worn tyres impair necessary adhesion to the road surface, particularly at
high speeds on wet roads. This could lead to “aquaplaning” (uncontrolled ve- hicle movement – “swimming” on a wet road surface).
WARNINGObserve the following information regarding the tyre inflation pressure.■The tyre control display does not absolve the driver of the responsibility to
ensure the correct tyre inflation pressure. Check the tyre inflation pressure at
regular intervals.■
Insufficient or excessive inflation pressure impairs handling – risk of acci-
dent!
■
If the inflation pressure is too low, the tyre will have to overcome a higher
rolling resistance. This will cause a significant increase in the temperature of
the tyre, especially at higher speeds. This can result in tread separation and a
tyre blowout. 
172General Maintenance

Always check the inflation pressure when the tyres are cold. Do not reduce the
higher pressure of warm tyres.
With greater additional load, adjust the tyre inflation pressure accordingly.
Driving style
Fast cornering, sharp acceleration and braking increase the wear of your tyres.
Balancing wheels
The wheels of a new vehicle are balanced. When driving, however, there are a
range of factors that may result in an imbalance. This may become apparent by
“vibration” in the steering.
Have the wheels rebalanced after replacing the tyres.
Wheel alignment errors
Incorrect wheel alignment at the front or rear leads to excess wear of the tyres.
Tyre damage
Drive over kerbs and other such obstacles slowly and at right angles wherever
possible in order to avoid damage to tyres and wheel trims.
We recommend checking your tyres and wheel rims for damage (punctures, cuts,
splits and bulges, etc.) on a regular basis. Remove foreign bodies (e.g. small
stones) from the tyre tread immediately.
Replacing wheels
If significantly greater wear is present on the front tyres, we recommend swap-
ping the front wheels with the rear wheels as shown in the diagram » Fig. 136.
You will then obtain approximately the same life for all the tyres.
We recommend that you swap the tyres every 10,000 km in order to achieve evenwear on all tyres and to ensure optimal service life for the tyres.
Storing tyres
Identify disassembled tyres so that the previous direction of rotation can be
maintained if the tyres are reassembled.
Always store wheels or tyres in a cool, dry place that is as dark as possible. Tyres
which are not fixed to a wheel trim should be stored upright.
Wear indicators
The base of the tread of the tyres has 1.6 mm high wear indicators installed.
These wear indicators are arranged evenly spaced around the circumference of the tyre a number of times depending on the make » Fig. 135 - 
. Markings on the
walls of the tyres through the letters “TWI”, triangular symbols or other symbols identify the position of the wear indicators.Tyre age
Tyres age and lose their original characteristics, even if they are not being used.
Therefore, we recommend not using summer or winter tyres older than 6 or 4 years old respectively.
New tyres
First read and observe the introductory information and safety warn-
ings
on page 172.
Only use radial tyres of the same type, size (rolling circumference) and tread pat-
tern on one axle on all four wheels.
The tyre/wheel combinations which are approved for your vehicle are indicated in
your vehicle documents.
Where possible, replace tyres by axle. Always fit the tyres with the deeper tread
depth to the front wheels.
