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 ignition 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. 190 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 255 or after changing or swapping wheels
⇒ page 255 you should - with the vehicle at a standstill and the engine run- ning - press ⇒ Fig. 190. 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. 

256Wheels and tyres
Wheel balance
The wheels on new vehicles are balanced. However, various factors encoun-
tered in normal driving can cause them to become unbalanced, which re-
sults in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause exces-
sive wear on steering, suspension and tyres. A wheel must also be reba-
lanced when a new tyre is fitted.
Incorrect wheel alignment
Incorrect wheel alignment causes excessive tyre wear, impairing the safety
of the vehicle. If tyres show excessive wear, you should have the wheel
alignment checked by a Technical Service.
WARNING
There is a serious danger of accidents if a tyre bursts during driving!
● The tyres must be replaced at the latest when the tread wear indica-
tors are worn ⇒ page 255. Failure to do so could result in an accident.
Worn tyres do not grip well at high speeds on wet roads. There is also a
greater risk of aquaplaning.
● At continuously high speeds, a tyre with insufficient pressure flexes
more. This causes it to overheat. This can cause tread separation and tyre
blow-out. Risk of accident. Always observe the recommended tyre pres-
sures.
● If tyres show excessive wear, you should have the running gear
checked by a Technical Service.
● Keep chemicals such as oil, fuel and brake fluid away from tyres.
● Damaged wheels and tyres must be replaced immediately!
For the sake of the environment
Under-inflated tyres will increase fuel consumption. Run-flat tyres*
Run-flat tyres allow you to continue driving even with a
punctured tyre, in the majority of cases.
In vehicles that are factory-fitted with run-flat tyres 1)
the loss of tyre
pressure is indicated on the instrument panel.
Driving with run-flat tyres (emergency running)
– Leave the ESC/ASR on (Electronic Stability Control), or switch it
on ⇒  page 71.
– Continue driving carefully and slowly (80 km/h (50 mph) maxi-
mum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (for example kerbs) or potholes.
– Pay attention if the ESC/ASR activates often, if smoke comes
from the tyres or there is a smell of rubber, the vehicle vibrates
or there are clattering noises. If any of these occur, stop the ve-
hicle.
The run-flat tyres have a tag on the side of the tyre, with the description:
“DSST”, “Eufonia”, “RFT”, “ROF”, “RSC”, “SSR” or “ZP”.
The sides of this type of tyre are reinforced. When the tyres lose air they are
supported on the sides (emergency driving).
The loss of pressure in the tyre is shown on the instrument panel. You can
then drive a maximum of 80 km (50 miles) and if the circumstances are fa-
vourable (for example, low load), even more. 

Wheels and tyres
The damaged tyre should be changed as soon as possible. The rim should
be checked in a specialised workshop to detect possible damage and re-
place it if necessary. We recommend you contact Technical Service. If more
than one tyre is being used under emergency conditions, this reduces the
distance which can be travelled.
Starting driving in emergency conditions
When loss in tyre pressure is displayed on the instrument panel, this means
that at least one tyre is being driven in emergency conditions ⇒ 
.
End of emergency operation
Do not drive on if:
● smoke is coming from one of the tyres,
● there is a smell of rubber,
● the vehicle vibrates,
● there is a rattling noise.
When is it no longer possible to continue driving even using run-flat tyres?
● If the Electronic Stability Control (ESC) does not function.
● If the tyre pressure monitoring system* does not work.
● If one of the tyres has been severely damaged in an accident, etc. If a
tyre has been badly damaged there is a risk that parts of the tread can be
thrown off and cause damage to the fuel lines, brake pipes or fuel filler.
● It is also advisable to stop driving if severe vibrations occur, or if the
wheel starts overheating and gives off smoke.
WARNING
When driving in emergency conditions, the driving quality of the vehicle
is considerably impaired.
● The maximum permitted speed of 80 km/h (50 mph) is subject to
road and weather conditions. Please observe legal requirements when
doing so.
● Avoid sharp turns and rapid manoeuvres, and brake earlier than usu-
al.
● Avoid driving over obstacles (for example kerbs) or potholes.
● If one or more tyres are being driven in emergency conditions, the
driving quality of the vehicle is impaired and there is a risk of accident.
Note
● The run-flat tyres do not “deflate” on losing pressure because they are
supported on the reinforced sides. Therefore defects in the tyre cannot be
detected with a visual inspection.
● Snow chains must not be used on front tyres used in emergency condi-
tions. 
New tyres and wheels
New tyres and wheels have to be run in.
The tyres and wheel rims are an essential part of the vehicle's design. The
tyres and rims approved by SEAT are specially matched to the characteris-
tics of the vehicle and make a major contribution to good road holding and
safe handling ⇒ 
.
Tyres should be replaced at least in pairs and not individually (i.e. both front
tyres or both rear tyres together). A knowledge of tyre designations makes it
easier to choose the correct tyres. Radial tyres have the tyre designations
marked on the sidewall, for example: 

Repairing a tyre
Fig. 202 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 268.
– 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. 202.
– 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 
