2. The tyre pressures should only be checked when the tyres are
cold. The slightly raised pressures of warm tyres must not be re-
duced.
3. Adjust the tyre pressure to the load you are carrying.
Tyre pressure
The correct tyre pressure is especially important at high speeds. The pres-
sure should therefore be checked at least once a month and before starting
a journey.
The sticker with the tyre pressure values can be found on the inside of the
tank flap. The tyre pressure values given are for cold tyres. Do not reduce
the slightly raised pressures of warm tyres ⇒ 
.
WARNING
● Check the tyre pressure at least once per month. Checking the tyre
pressure is very important. If the tyre pressure is too high or too low,
there is an increased danger of accidents - particularly at high speeds.
● A tyre can easily burst if the pressure is too low, causing an accident!
● At continuously high speeds, a tyre with insufficient pressure flexes
more. In this way it becomes too hot, and this can cause tread separation
and tyre blow-out. Always observe the recommended tyre pressures.
● If the tyre pressure is too low or too high, the tyres will wear prema-
turely and the vehicle will not handle well. Risk of accident!
For the sake of the environment
Under-inflated tyres will increase fuel consumption. Tyre pressure monitoring*
The tyre pressure monitoring system constantly checks the
pressure of the tyres.
The system warns the driver in the event of a loss of pressure by means of
symbols and messages in the instrument panel display.
Note that tyre pressure also depends on tyre temperature. Tyre pressure in-
creases about 0.1 bar for each 10°C in tyre temperature increase. The tyre
heats up while the vehicle is being driven and the tyre pressure will rise ac-
cordingly. For this reason, you should only adjust the tyre pressures when
they are cold (i.e. approximately at ambient temperature).
To ensure that the tyre pressure monitoring system works reliably, you
should check and, if necessary, adjust the tyre pressures at regular intervals
and store the correct pressures (reference values) in the system.
A tyre pressure information label is attached to the inside of the fuel tank
flap.
WARNING
● Never adjust tyre pressure when the tyres are hot. This may damage
or even burst the tyres. Risk of accident!
● An insufficiently inflated tyre flexes a lot more at high speeds and
causes significant heating of the tyre. Under these conditions, the tyre
bead may be released or the tyre may burst. Risk of accident!
For the sake of the environment
Under-inflated tyres lead to increased fuel consumption and tyre wear. 

Wheels and tyres
Significant tyre pressure loss
The tyre symbol  is displayed and indicates that the tyre pressure
of at least one tyre is insufficient.
– Stop the vehicle.
– Switch the engine off.
– Check the tyre(s).
– Change the wheel if necessary. 
Tyre pressure monitoring (RKA+)*
The tyre pressure monitor display on the instrument panel
indicates if the pressure is too low.
Fig. 189 Detailed view of
the centre console: But-
ton for the tyre pressure
monitoring system The tyre pressure monitoring system makes use of the ABS sensors to com-
pare the rolling circumference and the frequency characteristics of the
wheels. If the rolling circumference or frequency characteristic changes on
one or more wheels, the tyre pressure warning lamp  will light up. The
fault will also be indicated by a warning buzzer. The position of the affected
tyre will also be shown (if only one tyre is affected) on the centre display of
the instrument panel.
The rolling circumference and frequency characteristics can change if:
●
the tyre pressure is too low.
● the tyre has suffered structural damage.
● the wheels or the inflation pressures have been changed without initial-
ising the system (see Adjusting the tyre pressure settings).
● there is a greater load on the wheels of one axle (e.g. if you are carrying
more passengers or luggage).
● the road surface under the left wheels is different to the road surface un-
der the right wheels for a long period.
● when driving with snow chains.
Adjusting the tyre pressure settings (initialising the tyre pressure
monitoring system)
After any incident regarding the wheels of your vehicle, e.g. after modifying
the tyre pressure ⇒ page 253 or after changing or swapping wheels
⇒ page 253 you should - with the vehicle at a standstill and the engine run- ning - press ⇒ Fig. 189. The yellow warning lamp  will light up. Hold the
button down for 2 seconds until the warning lamp goes out and an acoustic
warning is given. You can now release the button.
If the wheels are subjected to extreme stress (e.g. heavy load), the tyre
pressure must be increased to the recommended value for the maximum
load (see the adhesive label on the inside of the fuel tank flap) and then
initialise the system. 

Tyre pressure warning lamp on
When you switch on the ignition, the tyre pressure warning lamp  will
light up for about 2 seconds. There is a fault in the system if the indicator
stays on permanently after switching on the ignition. The instrument panel
also display TMPS (Tyre Pressure Monitoring System). Please contact the
nearest specialised workshop as soon as possible.
The tyre pressure warning lamp  lights up if the tyre pressure on one or
more wheels is significantly lower than the tyre pressure setting which was
confirmed by the driver ⇒ 
.
WARNING
● If the tyre pressure warning lamp lights up  you must slow down
immediately and avoid any severe braking or steering manoeuvres. Stop
the vehicle as soon as possible and check the tyres and their pressure.
● The driver is responsible for maintaining correct tyre pressures.
Therefore, the tyre pressure must be regularly checked.
● Under certain conditions (e.g. driving at high speeds, on ice and snow
or on poor road surfaces) the tyre pressure warning lamp  may not light
up immediately or not at all.
● Please ask your Technical Service or specialised workshop whether
run-flat tyres can be used on your vehicle. Fitting this type of tyre in an
undue manner could lead to your driving licence being taken away from
you. Furthermore, it may led to damage to the vehicle or, under certain
circumstances, may cause accidents.
● If you change normal tyres for run-flat tyres or vice versa, the control
unit must be reprogrammed by the Technical Service or a specialised
workshop.
Note
If you did not press the button for the tyre pressure monitoring system to
confirm a new tyre pressure setting after making changes to the tyre pres-
sures or changing one or more wheels, the warning lamp  may light up
although the tyre pressures are correct. In this case, stop the vehicle as
soon as possible and, after examining the tyres, press the button for the
tyre pressure monitoring system. 

262If and when
Changing a wheel
Preparation work
What you must do before changing a wheel.
– If you have a flat tyre or puncture, park the vehicle as far away
from the flow of traffic as possible. Choose a location that is as
level as possible.
– All passengers should leave the vehicle. They should wait in a
safe place (e.g. behind the roadside crash barrier).
– Apply the handbrake firmly.
– Engage first gear .
– When towing a trailer: Unhitch the trailer from your vehicle.
– Take the tools and the spare wheel ⇒  page 259 out of the lug-
gage compartment.
WARNING
If you have a puncture in heavy traffic, switch on the hazard warning
lights and place the warning triangle in a visible location. This is for your
own safety and also warns other road users.
CAUTION
If you have to change the tyre on a gradient, block the wheel opposite the
wheel being changed by placing a stone or similar object under it to prevent
the vehicle from rolling away.
Note
Please observe legal requirements when doing so. 
Changing a wheel
Change the wheel as described below.
– Remove the wheel cover .
– Loosen the wheel bolts ⇒ page 263.
– Raise the vehicle with the jack ⇒ page 264.
– Take off the wheel with the flat tyre and then put on the spare
wheel ⇒ page 265.
– Lower the vehicle.
– Tighten the wheel bolts firmly in diagonal sequence with the
box spanner ⇒ page 263.
– Replace the cover. 
After changing a wheel
After changing the wheel, there are still tasks to complete. – Place the wheel with the defective tyre in the spare wheel well
and secure it.
– Put the tools and jack back in the luggage compartment. 

Repairing a tyre
Fig. 201 Repairing a tyre
Preparations
– If you have a flat tyre or puncture, park the vehicle as far away
from the flow of traffic as possible.
– Apply the handbrake firmly to prevent the vehicle from moving
accidentally on slopes.
– Engage first gear .
– Check whether a repair is possible using the Tyre Mobility Sys-
tem ⇒ page 266.
– Ensure that all passengers leave the vehicle and move away
from the danger area ⇒ 
.
– Take the tyre sealant can and the compressor out of the lug-
gage compartment. –
Stick the “max. 80 km/h” adhesive, which is included with the
tyre sealant can, onto the instrument panel where the driver will
see it.
Filling the tyre
– Shake the tyre sealant can well.
– Screw the enclosed filling hose onto the sealant can as far as it
will go. This will automatically pierce the foil sealing the can.
– Take the valve cap off the tyre valve and use the enclosed valve
insert tool to unscrew the valve insert ⇒ Fig. 201.
– Place the valve insert onto a clean surface.
– Remove the sealing plug from the filling hose and insert the
hose into the tyre valve.
– Hold the tyre sealant can upside down and fill the complete
contents of the can into the tyre.
– Then disconnect the hose and screw the valve insert firmly back
into the tyre valve.
Inflating the tyre
– Screw the compressor filling hose onto the tyre valve and plug
the connector into the cigarette lighter.
– Pump the tyre up to 2.0 to 2.5 bar and monitor the pressure
shown on the pressure gauge.
– If the tyre pressure remains lower than the value specified
above drive the vehicle approx. 10 metres forwards or back-
wards, so that the sealant can spread evenly in the tyre. If the 

269
If and when
pressure is still lower than the specification the tyre is too badly
damaged and cannot be repaired using the tyre sealant.
Final check
– After about 10 minutes, stop to check the tyre pressure.
– If tyre pressure is less than 1.3 bar, the tyre is too badly dam-
aged. Do not drive on! You should obtain professional assis-
tance.
WARNING
● If you have a puncture in heavy traffic, switch on the hazard warning
lights and place the warning triangle in a visible location. This is for your
own safety and also warns other road users.
● Make sure your passengers wait in a safe place (for instance behind
the roadside crash barrier).
● Please observe the manufacturer's safety notes on the compressor
and the instructions supplied with the tyre sealant can.
● If it is not possible to build up a tyre pressure of 2.0 bar within 6 mi-
nutes this means that the tyre is too badly damaged. Do not drive on!
● Seek professional assistance if the repair of a tyre puncture is not
possible with the sealing compound.
● If tyre pressure is less than 1.3 bar after driving about 10 minutes,
the tyre is too badly damaged. Do not drive on! Obtain technical assis-
tance.
CAUTION
Take special care if you have to repair a tyre on a slope.
Note
● Do not use the compressor for longer than 6 minutes. Otherwise, it
might overheat. When the compressor has cooled down, you can use it
again.
● If tyre sealant should leak out, leave it to dry and then pull it off like foil.
● After carrying out a tyre repair remember to buy a new tyre sealant can at
a specialised workshop. This will ensure that the Tyre Mobility System is op-
erative again.
● Please observe legal requirements when doing so. 

Bulbs
General information
You can change the following bulbs for exterior lights yourself:
● Main headlights: all bulbs (except xenon headlights)
● Tail lights: all bulbs
● Side turn signal bulb
The following bulbs can only be changed by a specialised workshop:
● Main headlights: Xenon* bulb ⇒ page 279
● Front fog lights: Bulb
As a rule, you require a certain degree of practical skill to change defective
bulbs. This applies in particular to those bulbs which are only accessible
from the engine compartment.
If in doubt, we recommend that you have defective bulbs changed by a spe-
cialised workshop or qualified mechanic.
If you do decide to change bulbs in the engine compartment yourself, be
aware of the safety risks involved ⇒ page 234 ⇒ 
in Types of bulbs on
page 273. The name of many of the lamps fitted by SEAT ends in "LL". This means Long
Life. These lamps are used for functions with a long service time (dipped
beam, side lights, daylight driving, etc.). This does not apply to lamps with
a shorter service time (turn signals, etc.). A lamp with the same name ex-
cept for the last two letters, "LL“ or “SLL”, is compatible, but will have a
service life of approximately half of the LongLife lamps.
When replacing lamp bulbs, the same type of bulb as originally fitted
should always be used where possible.
