Never place any objects on the surfac
e of the front passenger airbag in
the dash panel.Driver's knee airbag*Description of the driver's knee airbags, The knee airbag reduces the ri
sk of injury to the legs.
The driver's knee airbag is located in th
e lower part of the dash panel below the
steering column
⇒fig. 173
. The fitting position is show
n in a picture on the side
surface of the dash panel on the driver's side. The driver's knee airbag is complementary
to the three-point seat belt and offers
adequate protection to the knees of the driver.
Please note that an airbag can
only offer you optimal protection in combination with a seat belt which is fastened
.
Apart from their normal protective
function, a further task of the
seat belt
is to also
hold the driver in a correct seated position in
the event of a frontal collision so as to
enable the knee airbag to offer the maximum protection.
You should therefore always fasten the seat
belts, not only because this is required
by law, but also for safety reasons and for your own protection
⇒page 168, “Why
seat belts?”.Function of the driver's knee airbagsThe airbag system is designed in such a way that the driver's knee airbag is deployed together with the belt tensioner in the event of a frontal collision of major severity. If an airbag is deployed, th
e airbag is filled with propellant gas. The airbags inflate
in fractions of a second and at a high spee
d in order to be able to offer that addi-
tional protection in the event of an accident. A grey white, non harmful gas is released when airbag is inflated. This is perfectly normal and is not an indicati
on of a fire in the vehicle.
The forward movement of the body is cush
ioned when it makes contact with the
fully inflated airbag and the risk of injury
to the legs of the driver is thus reduced.
Important safety information on the driver's knee airbag
WARNING
•
The surface of the airbag module in
the lower part of the dash panel
below the steering column must not be stuck onto, covered or modified in any other way. These parts should only be cleaned with a dry cloth or a cloth moistened with water. No objects must be attached to the cover of the airbag module or be located within the immediate area.•
No modifications of any kind may be made to parts of the airbag system.
Any work on the airbag system including installing and removing system components because of other repair work (e.g. removing the steering wheel) must only be carried out by a specialist garage.•
Never carry out changes on the front bumper or on the body.

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 other assign-
ment of tyres and wheels) can influence the function of the ESP
⇒page 241,
“Accessories, changes and replacement of parts”.Electronic Differential Lock (EDL)* The electronic differential lock pr
events 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 conditio
ns 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 proces
s 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 driv
en 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
•
Depress the accelerator carefully when accelerating on uniformly slip-
pery road surfaces, such as ice and sn
ow. 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 ESP warning light comes on,
this may also indicate a fault in the
EDL. Please have the car inspected as s
oon as possible by a specialist garage.

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 conditio
ns of the road surface are unfavourable.
Operating principle The TCS switches on automatically when th
e 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 redu
cing the engine speed. Th
is occurs at all speeds.
The TCS operates in combination with the ABS
⇒page 197. The TCS will not func-
tion 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 38.
Switching off You can switch the TCS off and on again
as you wish by pressing the button
⇒ fig. 191
. The TCS warning light lights up in the instrument cluster when the TCS is
switched off
 ⇒page 38.
The TCS 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. Examples:•
when driving with snow chains
•
when driving in deep snow or on a loose surface
•
when it is necessary to rock a car free when it has become stuck.
then you should switch on the TCS again.
WARNING
You should always adjust your style of driving to the conditions of the road surface and the traffic situation. The increased safety offered must not tempt you to take greater risks than otherwise - risk of an accident!
Note
•
All four wheels must be fitted with the same tyres in order to achieve problem-
free operation of the TCS. 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 other assign-
ment of tyres and wheels) can in
fluence the function of the TCS
⇒page 241,
“Accessories, changes and replacement of parts”.Active driver-steering recommendation (DSR)*Vehicles with ESP are equi
pped with active driver-steering recommendation (DSR).
This function indicates to the driver in critical situations a steering recommendation in order to stabilise the vehicle. The active driver-steering recommendation is acti- vated, for example, on the right and left
vehicle side when
braking sharply on
different road surfaces.

the brake light stops flashing and the hazard warning light system switches on. The hazard warning light system is switched
off 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 gene
rated 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.Antilock brake system (ABS)ABS prevents the wheels locking when braking.General The ABS contributes significan
tly 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 fu
ll brake 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. Th
e 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 tend
ing to lock. This control cycle is notice-
able 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 optima
lly control the brake application in this
braking range. Never interrupt the application of the brakes!
WARNING
•
The ABS can also not overcome the physic
al limits of your vehicle. Please
do not forget this, particularly when driv
ing on icy or wet road surfaces. If the
ABS is operating within the control ra
nge, 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 po
ssible and adjust yo
ur style of driving
to take account of the ABS fault in the meantime since you will not know how great the damage is.

Tyre inflation pressu
re-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 rolling
circumference of a wheel is changed, the warning light°
 lights up in the instru-
ment cluster
⇒page 39. 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 tyre inflation pressure-control system After changing the tyre inflation pressures or after changing one or several wheels, a basic setting of the system must be carried out as follows.•
Inflate all tyres to the specified inflation pressure

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 mano
euvres. 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 correc
t 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 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 carefully bring the vehi
cle to a standstill without
sudden steering movements and without sharp braking.

Changing wheels aroundIf 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. 212
.
You will then obtain approximately the same life for all the tyres. It may be advantageous to swap the tyre
s over “crosswise” when certain types of
wear characteristic arise on
the running surface of the tyres (but not in the case of
unidirectional tyres). The co-workers of the authorised Škoda Service Partners are extensively familiar with the combination possibilites. 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 wheelsTyres and wheel rims are important design
elements. One should therefore use the
tyres and wheel rims which have been released for use by Škoda Auto. They are exactly matched to the vehicle type and th
erefore contribute significantly to good
road holding and safe driving characteristics
⇒
.
Only fit radial tyres of the same type on
all 4 wheels, size (rolling circumference)
and, if possible, the same tread pattern on one axle. The authorised Škoda Service Partners have access to the most current information about which tyres we have rele
ased for use on your vehicle.
We recommend that you have any work rela
ting to tyres or wheels carried out by
an authorised Škoda Service Partner
. The authorised Škoda Service Partners
have all of the necessary special tools
and replacement parts available plus the
required specialist knowledge and are also in a position to properly dispose of the old tyres. A large number of authorised Škod
a Service Partners also have an attrac-
tive range of tyres and wheels available. The tyre/wheel combinations which are appr
oved for your vehicle are indicated in
your vehicle documents. Approval and lice
nsing may differ according to the legis-
lation prevailing in individual countries. Proper knowledge of the tyre data makes it easier for you to select the correct type of tyre. Tyres do, for example, have the following
inscription
on their walls:
205 / 55 R 16 94 V
What this means is: The following
speed restrictions

Spare wheel*The spare wheel lies in a well under the floor covering of the luggage compartment and is fixed in place using special screws
⇒fig. 216
.
Before removing the spare wheel, you must take out the box with the vehicle tool kit box
⇒page 244, fig. 215
.
One should check the inflation pressure in the spare wheel (at best when generally checking the tyre air pressures - see sign on the fuel filler flap
⇒page 235) to
ensure that the spare wheel is always ready to use. Temporary spare wheel A warning label displayed on the rim of the temporary spare wheel indicates that your vehicle is equipped with a temporary spare wheel. Please observe the following notes when driving with a temporary spare wheel:•
After fitting on the wheel, the warning stic
ker must not be concealed (e.g. by the
wheel trim).•
Do not drive with this spare wheel at more than 80 km/h - risk of accident. Avoid
accelerating at full throttle, sharp braking and fast cornering.•
The inflation pressure for this spare wheel is identical to the inflation pressure
of the standard tyres. The temporary spare wheel R 18 must have an inflation pres-sure of 420 kPa (4.2 bar)!
•
Use this spare wheel only to reach the nearest specialist garage as it is not
intended for continuous use.•
No other summer or winter tyres must
be mounted on the rim of the spare
wheel R 18.Changing a wheelPreliminary workThe following steps should be carried out before actually changing the wheel. – If it is necessary to change a wheel, park the vehicle as far away as
possible from the traffic flow. The place you choose should be
level
.
–Have
all the occupants get out.
While changing a wheel, the occu-
pants of the vehicle should not stan
d on the road (e.g. behind a crash
barrier).
– Apply the
handbrake
firmly.
–Engage
1st gear
or if your vehicle is fitted with an automatic gearbox,
position the
selector lever into position P
.
– If a trailer is coupled, uncouple it. – Take the
vehicle tool kit

•
If you find yourself in flowing traffic switch on the hazard warning lights
system and place the warning triangle
on the side of the road at the
prescribed distance from
your vehicle while obse
rving all national legal
provisions. In this way you are protecting not only yourself but also other road users.

page 248.
– Jack up the vehicle until the wheel to
be changed is clear of the ground
⇒
page 249.
– Unscrew the wheel bolts and place them on a clean surface (cloth,
paper etc.).
– Take off the wheel. – Fit on the spare wheel and tighten the wheel bolts slightly. –Lower the car.
– Tighten the wheel bolts firmly, al
ternately and diagonally using the
wheel wrench (crosswise) and last the safety wheel bolt*
⇒
page 248.
– Mount the full wheel trim/w
heel trim cap or the caps.
Note
•
All bolts must be clean
and must turn easily.
•
You must never grease or oil the wheel bolts!
•
When fitting on unidirectional tyres, ensure that the tyres rotate in the correct
direction

.
– Stow the vehicle tool kit in the space provided.–
Check
the
tyre pressure
on the spare wheel just mounted as soon as
possible.
– Have the
tightening torque
of the wheel bolts
checked
with a torque
wrench as soon as possible. Steel and light alloy wheels must be tight-ened to a tightening torque of
120 Nm
.
– Have the defective tyre repaired as soon as possible.
