The driver's seat should be adjusted in such a way that the pedals can be fully
pressed to the floor with slightly bent legs.
The seat backrest on the driver's seat should be adjusted in such a way that the
upper point of the steering wheel can be easily reached with slightly bent arms.
Correct adjustment of the seats is particularly important for:
› safely and quickly reaching the controls;
› a relaxed, fatigue-free body position;
› achieving the maximum protection offered by the seat belts and the airbag
system.
WARNING■ Only adjust the driver's seat when the vehicle is stationary – risk of accident!■Caution when adjusting the seat! You may suffer injuries or bruises as a re-
sult of adjusting the seat without paying proper attention.■
As the electric front seats can also be adjusted when the ignition is switch-
ed off (even when the ignition key is withdrawn), never leave children unat-
tended in the car.
■
The seat backrests must not be angled too far back when driving otherwise
this will affect proper operation of the seat belts and of the airbag system –
risk of injury!
■
Never carry more people than the number of seats in the vehicle.
WARNING (Continued)■ Each occupant must correctly fasten the seat belt belonging to the seat.
Children must be fastened » page 154, Transporting children safely with a
suitable restraint system.■
At all times, the front seats and head restraints must be adjusted to match
the person's body size and the seat belt must be attached properly to provide
the most effective levels of protection to passengers.
■
Always keep your feet in the footwell when the car is being driven – never
place your feet on the instrument panel, out of the window or on the surfaces
of the seats. This is particularly important for the front seat passenger. You
will be exposed to increased risk of injury if it becomes necessary to apply the
brake or in the event of an accident. If an airbag is deployed, you may suffer
fatal injuries when adopting an incorrect seated position!
■
The driver must maintain a distance of at least 25 cm from the steering
wheel, and a distance of at least 10 cm between the legs and the dash panel at the height of the knee airbag. The front passenger must maintain a dis-
tance of at least 25 cm to the dash panel. Not maintaining this minimum dis-
tance will mean that the airbag system will not be able to properly protect you
– hazard!
■
Ensure that there are no objects in the driver's footwell as they may get
caught behind the pedals when driving or applying the braking. You would
then no longer be able to operate the clutch, brake or accelerate.
■
Do not transport any objects on the front passenger seat except objects
(e.g. child safety seat) provided for this purpose – risk of accident!
Note
■ After a certain time, play can develop within the adjustment mechanism of the
backrest angle.■
For safety reasons, it is not possible to store the seated position in the seat
memory and remote control key memory if the inclination angle of the seat back-
rest is more than 102° in relation to the seat cushion.
■
Each new driver seat and external mirror position that is saved will overwrite
the existing setting.

CAUTION■If a warning signal sounds for about 3 seconds after activating the system and
there is no obstacle close to your car, this indicates a system fault. The fault is
confirmed additionally when the symbol  flashes in the button 
.
! is displayed
in the error area of the Infotainment display. Have the fault rectified by a ŠKODA
specialist garage.
■
The sensors must be kept clean (free of ice, etc.) to enable the parking aid to
operate properly.
Note
■ The signal tones for front obstacle recognition are factory-set to be higher than
for rear obstacle recognition.■
If not all fields around the vehicle are shown after the system is activated, the
vehicle will need to be moved a few metres forwards or in reverse.
■
If the parking aid is activated and the selector lever of the automatic gearbox is
in the position P (the vehicle cannot move), the warning signal is interrupted and
no obstacles are displayed.
■
Additional mounted modules, such as a bicycle carrier, can impair the function of
the parking aid.

The parking aid is part of the park assist system, therefore the information and
safety guidelines » page 114, Parking aid must be read and observed.
Park Assist (in the following referred to as the system) helps drivers park in suita- ble parallel and perpendicular parking places and also to manoeuvre out of paral- lel parking spaces.
The system only operates if the ignition is switched on.
During the parking procedure the system only takes over the steering move- ments, the pedals continue to be operated by the driver.
When the system is activated, 
the warning light

» Fig. 109 on page 117 - 
lights up in the button.
The traction control system (TCS) must always be switched on when parking.
The function of the system is based on: › the measurement and evaluation of the size of parking spaces when driving,
› the determination of the correct position of the vehicle for parking,
› the calculation of the line on which the vehicle drives backwards into the park-
ing space or forwards from the parking space;
› the automatic turning of the front wheels when parking in, or manoeuvring out
of the parking space.
WARNING■ The system does not exempt the driver from his/her responsibility for park-
ing in and manoeuvring out of the parking space.■
External sound sources can have a detrimental effect on parking in and ma-
noeuvring out of the parking space. Under unfavourable conditions, objects or
people may not be recognised.
■
When parking in, and manoeuvring out of parking spaces, the system auto-
matically executes quick steering movements. While it is doing so, do not place your hands between the steering wheel - risk of injury!
CAUTION
■ If other vehicles are parked behind or on the kerb, the system guides your vehi-
cle beyond the kerb or onto it. Ensure that the wheels or the wheel rims of your
vehicle are not damaged and if necessary intervene in time.■
Under certain circumstances, surfaces or structures of certain objects such as
wire mesh fences, powder snow, etc., cannot be recognised by the system.
■
The evaluation of the parking space and the parking procedure depends on the
circumference of the wheels. The system only works correctly if the vehicle is fit-
ted with the wheel size approved by the manufacturer. If wheels other than those approved by the manufacturer are mounted, the resulting position of the
vehicle in the parking space can differ slightly. This can be avoided by readjusting
the system at a ŠKODA specialist garage. Under certain circumstances, the sys-
tem may not function correctly, for example, if the vehicle is fitted with snow chains or a temporary spare wheel.

116Using the system

What influences the driving safety?First read and observe the introductory information and safety warn-ings
on page 138.
The driver is fully responsible for himself and his occupants. If your driving safety is effected, you place yourself and the oncoming traffic at risk.
The following guidelines must therefore be observed. › Do not get distracted from concentrating on the traffic situation, e.g. by your
passengers or mobile phone calls.
› Never drive when your driving ability is impaired, e.g. through medication, alco-
hol or drugs.
› Keep to the traffic regulations and the permissible speed limit.
› Always adjust the driving speed to the road, traffic and weather conditions.
› Take regular breaks on long journeys – at least every two hours.

Introduction
This chapter contains information on the following subjects:
Correct seated position for the driver
140
Correct seated position for the front passenger
140
Correct seated position for the occupants on the rear seats
140
Examples of an incorrect seated position
140WARNING■ At all times, the front seats and head restraints must be adjusted to match
the person's body size and the seat belt must be attached properly to provide
the most effective levels of protection to passengers.■
Always assume the correct seated position before setting off and do not
change this position while driving. Also advise your passengers to adopt the
correct seated position and not to change this position while the car is mov-
ing.
■
If the occupant adopts an incorrect seated position, he is exposed to life-
threatening injuries, in case he is hit by a deployed airbag.
WARNING (Continued)■ If the occupants on the rear seats are not sitting upright, the risk of injury is
increased due to incorrect routing of the seat belt.■
The driver must maintain a distance of at least 25 cm from the steering
wheel, and a distance of at least 10 cm between the legs and the dash panel at the height of the knee airbag. The front passenger must maintain a dis-
tance of at least 25 cm to the dash panel. Not maintaining this minimum dis-
tance will mean that the airbag system will not be able to properly protect you
– hazard!
■
When driving, hold the steering wheel with both hands firmly on the outer
edge in the 9 o'clock and 3 o'clock position. Never hold the steering wheel in
the 12 o'clock position or in any other way (e.g. in the middle or inner edge of
the steering wheel). In such cases, you could severely injure the arms, hands
and head when the driver airbag is deployed.
■
The seat backrests must not be angled too far back when driving otherwise
this will affect proper operation of the seat belts and of the airbag system –
risk of injury!
■
Ensure that there are no objects in the driver's footwell as they may get
caught behind the pedals when driving or applying the braking. You would
then no longer be able to operate the clutch, brake or accelerate.
■
Always keep your feet in the footwell when the car is being driven – never
place your feet on the instrument panel, out of the window or on the surfaces
of the seats. You will be exposed to increased risk of injury if it becomes nec-essary to apply the brake or in the event of an accident. If an airbag is de-
ployed, you may suffer fatal injuries when adopting an incorrect seated posi-
tion!

139Passive Safety

Airbag system
Description of the airbag system
Introductory information
The airbags inflate in fractions of a second and at a high speed to offer additional protection in the event of an accident.
The functional status of the airbag system is indicated by the indicator light  in
the instrument cluster » page 19.
The airbag system (according to vehicle equipment) consists of: › an electronic control unit;
› Front airbags for the driver and front seat passenger
» page 147;
› a driver’s knee airbag
» page 148;
› side airbags
» page 149;
› head airbags
» page 150;
› an airbag warning light in the instrument cluster
» page 19;
› a key switch for the front seat passenger airbag
» page 151;
› a warning light in the middle of the dash panel to indicate the front seat pas-
senger airbag is switched off » page 151.
WARNING■
The airbag is not a substitute for the seat belt, but instead forms part of the
complete passive vehicle safety concept. Please note that an airbag can only
offer you optimal protection in combination with a seat belt which is fas- tened .■
To ensure passengers are protected with the greatest possible effect when
the airbag is deployed, the front seats must be correctly adjusted to match
the body size » page 139, Correct seated position .
■
If you do not fasten the seat belts when driving, lean too far forward or
adopt an incorrect seated position, you are exposing yourself to increased risk of injury in the event of an accident.
■
If there is a fault, have the airbag system checked immediately by a ŠKODA
specialist garage. Otherwise, there is a risk of the airbag not being activated in
the event of an accident.
WARNING (Continued)■ No modifications of any kind must be made to parts of the airbag system.
Any work on the airbag system including the installation and removal of sys-
tem components due to other repair work (e.g. removal of the steering wheel)
must only be carried out by a ŠKODA specialist garage.■
Never make any changes to the front bumper or bodywork.
■
It is prohibited to manipulate individual parts of the airbag system as this
might result in the airbag being deployed.
■
The protective function of the airbag system is sufficient for only one acci-
dent. The airbag system must then be replaced if the airbag has been de-
ployed.
■
The airbag system needs no maintenance during its working life.
■
If you sell your vehicle, provide the complete vehicle documentation to the
new owner. Please note that the information relating to the possibility of de-
activating the front passenger airbag must be included!
■
When disposing of vehicle or parts of the airbag system, it is important to
comply with the national legal requirements.

Airbag deployment
The airbag system is only functional when the ignition is switched on.
When the airbags are deployed they fill with gas and inflate.
A grey white or red, non-harmful gas is released when the airbag is inflated. This
is perfectly normal and is not an indication of a fire in the vehicle.
In certain accident situations, the several airbags may be deployed simultaneous- ly.
The airbags are not deployed in the case of minor frontal and side collisions, rear-
end collisions, tilting of the vehicle and vehicle rollover.
Deployment factors
It is not possible to generally determine which deployment conditions apply to the airbag system in every situation. An important role is played by factors such as the type of object that the vehicle hits (hard, soft), the impact angle, vehicle
speed, etc.
A decisive factor for the deployment of the airbags is the deceleration which oc- curs. The control unit analyses the nature of the collision and activates the rele-
vant restraint system. If the vehicle deceleration which occurs and is measured 
146Safety

during the collision remains below the prescribed reference values specified in
the control unit, the airbags are not deployed although the vehicle may well suf-
fer severe damage to the bodywork as a consequence of the accident.
The following will be deployed in the event of a severe frontal collision: › driver’s front airbag;
› passenger’s front airbag;
› driver’s knee airbag.
The following will be deployed in the event of a severe side collision: › front side airbag on the side of the accident;
› rear side airbag on the side of the accident;
› head airbags on the side of the accident.
In the event of an accident in which the airbags are deployed:
› the interior lighting comes on (if the switch for the interior light is in the door
contact position),
› the hazard warning light is switched on;
› all the doors are unlocked;
› the fuel supply to the engine is interrupted.
Front airbags
Fig. 131
Driver airbag in the steering wheel/front passenger airbag in the
dashboard
Fig. 132
Safe distance to steering wheel/inflated airbags
In the event of a severe frontal collision, the front airbag system offers additional
protection for the head and chest area of the driver and front passenger.
The front airbag for the driver is housed in the steering wheel » Fig. 131 – 
.
The front airbag for the front seat passenger is located in the dash panel above
the stowage compartment 
– » Fig. 131 .
When the airbags are deployed, they inflate in front of the driver and front pas-
senger » Fig. 132 - 
. The forward movement of the driver and of the front pas-
senger is cushioned when they make contact with the fully inflated airbag and
the risk of injury to head and chest is thus reduced.
The airbag allows the gas to flow out of the inflated airbag in a controlled manner(depending on the load of the particular car occupant) in order to cushion head
and chest areas. The airbag then deflates subsequently to such an extent, after
an accident, to again provide a clear view forward.
WARNING■ For the driver and front passenger, it is important to maintain a distance of
at least 25 cm to the steering wheel or dashboard A » Fig. 132 . Not maintain-
ing this minimum distance will mean that the airbag system will not be able to
properly protect you – hazard! The front seats and the head restraints must always also be correctly adjusted to match the body size of the occupant.■
The airbag develops enormous forces when triggered, which can lead to in-
juries if the sitting position or seated position is not correct.
■
There must not by any further persons, animals or objects positioned be-
tween the front seated occupants and the deployment area of the airbag. 
147Airbag system

WARNING (Continued)■Never transport children on the front seat of a vehicle without using a prop-
er restraint system. If airbags are deployed in the event of an accident, the
child might suffer severe or even fatal injuries!■
It is essential to always switch off the front passenger airbag when attach-
ing a child safety seat to the front passenger seat where the child is seated
with its back facing in direction of travel » page 151, Deactivating airbags . If
this is not done, there is a risk of the child suffering severe or even fatal inju- ries if the front passenger airbag is deployed. When transporting a child on
the front passenger seat, pay attention to any relevant national regulations
regarding the use of child safety seats.
■
The steering wheel and the surface of the airbag module in the dash panel
on the passenger side must not have stickers attached, be covered or modi-
fied in any other way. These parts should only be cleaned with a cloth that is
dry or has been moistened with water. No objects such as cup holders, mobile
phone mounts, etc. must be attached to the covers of the airbag modules or
be located within their immediate vicinity.
■
Never place objects on the surface of the front passenger airbag module in
the dash panel.

Driver’s knee airbag
Fig. 133
Driver's knee airbag below the
steering column
The driver's knee airbag offers adequate protection for the driver's legs.
The driver's knee airbag is located in the lower part of the dash panel below the steering column » Fig. 133.
In the event of a severe frontal collision, the driver's knee airbag and front airbags are deployed.
The forward movement of the body is cushioned when it makes contact with the
fully inflated airbag and the risk of injury to the legs of the driver is thus reduced.WARNING■ Adjust the driver's seat in a forward/back direction so that there is a gap of
at least 10 cm between the legs and the dash panel in the vicinity of the knee
airbag B
» Fig. 125 on page 140. If it is not possible to meet this requirement
due to your body size, visit a ŠKODA specialist garage.
■
The surface of the airbag module in the lower part of the dash panel below
the steering column not have stickers attached, be covered or modified in any
other way. This part should only be cleaned with a cloth that is dry or has
been moistened with water. No objects must be attached to the cover of the
airbag module or located within the immediate vicinity.
■
Do not attach any bulky and heavy objects (bunch of keys etc.) to the igni-
tion key. These can be ejected by the knee airbag when it is deployed and can
cause injuries.

186WARNING■ During the first 500 km, new tyres do not offer optimum grip and appropri-
ate care should therefore be taken when driving – risk of accident!■
Never drive with damaged tyres – risk of accident!
■
Never exceed the maximum permissible load bearing capacity of mounted
tyres.
■
Immediately replace damaged wheel rims or tyres.
■
On all four wheels, use only radial tyres of the same type, size (rolling cir-
cumference) and the same tread pattern.
■
Only use those tyres or wheel rims which have been approved by ŠKODA for
your model of vehicle. Failure to observe this instruction will adversely affect the road safety of your vehicle – risk of accident!
■
The maximum permissible speed for your tyres must not be exceeded under
any circumstances – risk of an accident resulting from tyre damage and loss of
control of the vehicle.
WARNING (Continued)■ If the inflation pressure is too low, the tyre must perform a greater rolling
resistance. At higher speeds the tyre will warm up as a result of this. This can
result in tread separation and a tyre blowout.■
For safety reasons, do no replace tyres individually.
■
Never use tyres if you do not know anything about the condition and age.
■
You must have your tyres replaced with new ones at the latest when the
wear indicators have been worn down.
■
Worn tyres do not provide the necessary adhesion to the road surface par-
ticularly at high speeds on wet roads. One could experience “aquaplaning” (uncontrolled movements of the vehicle – “swimming” on a wet road surface).
■
Do not use summer or winter tyres that are older than 6 years or 4 years re-
spectively.
■
The wheel bolts must be clean and must turn easily. Never treat them with
grease or oil.
■
If the wheel bolts are tightened to a too low tightening torque, the rim can
come loose when the car is moving – risk of accident! A tightening torque
which is too high can damage the bolts and threads and this can result in per-
manent deformation of the contact surfaces on the rim.
■
In case of incorrect treatment of the wheel bolts, the wheel can loosen
when the car is moving – risk of accident!
■
Never drive with more than one spare wheel mounted.
■
Only use the spare wheel while absolutely necessary.
■
The snow chains cannot be used on the spare wheel.
■
An incorrect wheel alignment at the front or rear impairs handling - risk of
accident!
■
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.
■
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 ŠKODA specialist garage to have the vehicle checked.
■
To low or too high inflation pressure impairs handling - risk of an accident!
■
The national legal requirements 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. 
181Wheels

CAUTION■If a spare wheel is used that is not identical to the fitted tyres, the following
must be observed » page 184, Spare wheel .■
Protect the tyres from contact with oil, grease and fuel.
■
Replace lost dust caps.
■
If, in the event of a puncture, it is necessary to fit a spare wheel with a tyre
without a dedicated running direction or the opposite running direction, drive carefully as the optimum characteristics of the tyre are no longer applicable in
this situation.
■
The tyre control display does therefore not replace the regular tyre inflation
pressure control, as the system cannot detect an even loss of pressure.
■
The system 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 or sharp braking.
■
To ensure a proper functioning of the tyre control display, it is necessary to re-
peat the basic setting every 10 000 km or once a year.
For the sake of the environment
Tyres which are insufficiently inflated increase your fuel consumption.
Note
■ We recommend that any work on the wheels or tyres is carried out by a ŠKODA
Partner.■
We recommend that you use wheel rims, tyres, full wheel trims and snow chains
from ŠKODA Original Accessories.

Changing wheels around
First read and observe the introductory information and safety warn-
ings on page 181.
The life of tyres depends on the inflation pressure, driving style, and other cir-
cumstances. If you follow the advice below you can extend the life of your tyres.
Tyre pressure
Check the tyre pressure, including that of the spare wheel, at least once a month and also before setting off on a long journey.
The tyre inflation pressures for summer tyres are indicated on the inside of the
fuel filler flap » Fig. 155 –
. The inflation pressures for
winter tyres are 20 kPa
(0.2 bar) higher than those for summer tyres.
The tyre pressure should be at the highest pressure specified for your vehicle at all times. 
