brake on gravel or on fresh snow on a
slippery surface. WARNING
● The anti-lock brake system cannot defy the
laws of physics. Slippery and wet roads are
dangerous even with ABS! If you notice that
the ABS is working (to counteract locked
wheels under braking), you should reduce
speed immediately to suit the road and traffic
conditions. Do not let the extra safety fea-
tures tempt you into taking any risks when
driving.
● The effectiveness of ABS is also determined
by the tyres fitted ››› page 175.
● If the ru
nning gear or brake system is modi-
fied, the effectiveness of the ABS could be se-
verely limited. Drive wheel traction control system
(ASR)
The traction control system prevents the driv-
en wheels from spinning when the vehicle is
accelerating.
Description and operation of the traction
control system during acceleration (ASR
On front-wheel drive vehicles, the ASR sys-
tem intervenes, reducing engine power and
preventing the driven wheels from slipping
during acceleration. The system works in the entire speed range in conjunction with ABS.
If a failure occurs in the ABS, the ASR will al-
so stop working.
TCS helps the car to start moving, accelerate
and climb a gradient in slippery conditions
where this may otherwise be difficult or even
impossible.
The ASR automatically switches on when the
engine is started. If necessary, it may be
turned on or off by briefly pushing the button
on the centre console.
When the ASR is switched off, the
 OFF warning lamp will light up. The ASR should
normally be left on. Only in exceptional cir-
cumstances, when slipping of the wheels is
desired, should it be disconnected.
●
With compact temporary spare wheel.
● When using the snow chains.
● When driving in deep snow or on soft ter-
rain.
● When the vehicle is bogged-down, to free it
by “rocking.”
The ASR should be switched on again as
soon as possible. WARNING
● Remember that not even the ASR can defy
the laws of physics. This should be kept in
mind, particularly on slippery and wet roads
and when towing a trailer. ●
Always adapt your driving style to suit the
condition of the roads and the traffic situa-
tion. The greater safety provided by the ASR
should not encourage you to run any risks. CAUTION
● To ensure that the ASR works correctly,
identical tyres should be fitted on all four
wheels. Any differences in the rolling radius
of the tyres can cause the system to reduce
engine power when this is not desired.
● Any modifications made to the vehicle (for
example, to the engine, brake system, run-
ning gear or to the combination of wheels
and tyres) may affect the operation of the
ABS and ASR. XDS*
When taking a curve, the driveshaft differen-
tial mechanism allows the outer wheel to turn
at a higher speed than the inner wheel. In
this way, the wheel that is turning faster (out-
er wheel) receives less drive torque than the
inner wheel. This may mean that in certain
situations the torque delivered to the inner
wheel is too high, causing the wheels to
spin. On the other hand, the outer wheel is
receiving a lower drive torque than it could
transmit. This causes an overall loss of lateral
grip on the front axle, resulting in understeer
or “lengthening” of the trajectory.

Operation
Safety

Operation
The XDS system can detect and correct this
effect via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
of that wheel. This means that the driver's
desired trajectory is much more precise,
The XDS system works in combination with
the ESC and is always active, even when ASR
traction control is disconnected.
Brake servo The brake servo increases the pressure you
apply to the brake pedal. It works
only when
the engine is running .
If the brake servo is not functioning, e.g. due
to a malfunction, or if the vehicle is being
towed, you will have to press the brake pedal
considerably harder to make up for the lack
of servo assistance. WARNING
The braking distance can also be affected by
external factors.
● Never let the vehicle coast with the engine
switched off. Failure to follow this instruction
could result in an accident. The braking dis-
tance is increased considerably when the
brake servo is not active.
● If the brake servo is not working, for exam-
ple when the vehicle is being towed, you will have to press the brake pedal considerably
harder than normal.

SEAT Parking System Plus*:
description The Parking System Plus is an acoustic and
optical parking aid.
Sensors are located in the front and rear
bumpers. When the sensors detect an obsta-
cle, you are alerted by audible and optical
warnings. The measuring range of the sen-
sors starts at approximately:FrontSide0.90
Centre1.20
RearSide0.60
Centre1.60
The audible warnings sound with increasing
frequency as you approach the obstacle.
When the vehicle is less than 0.30 m away
from the obstacle, the warning tone will
sound continuously. Stop moving immediate-
ly!
The volume of the warning beeps will gradu-
ally decrease after about 4 seconds if the ve-
hicle remains at a constant distance from a
detected obstacle (it does not affect the per-
manent acoustic signal). Activating/deactivating

with a discontinuous beep indicate the pres-
ence of an obstacle. As the vehicle gets clos-
er to the obstacle, the colour of the segment
changes to red and the acoustic signal beeps
continuously. When the penultimate segment
is displayed, this means that the vehicle has
reached the collision zone. Stop moving im-
mediately!

Checking and refilling levels
LPG quality and consumption
Quality requirements for LPG are regulated
for all Europe in DIN EN 589 and permit the
use of LPG throughout Europe.
A difference is drawn between winter gas and
summer gas. Winter gas has a higher propor-
tion of propane gas. As a result, the driving
range of winter gas may be lower (due to in-
creased consumption) than that of summer
gas.
LPG supplier network
The number of LPG pumps is constantly in-
creasing.
Lists of existing LPG pumps may be found on
Internet.
LPG safety A series of collision tests performed on this
vehicle while running with LPG have con-
firmed its high level of safety.
The safety of the LPG system guarantees op-
eration without risk. The following safety
measures have been adopted:
● The LPG tank has a solenoid valve which
closes automatically when the engine is
switched off (ignition off) or when running on
petrol. ●
A solenoid type main valve disconnects the
supply of gas to the engine compartment
when the engine is switched off or running
on petrol.
● A safety valve in the LPG tank with pipes to
the outside prevents the gas from entering
the vehicle interior.
● All anchorage points and materials have
been designed to ensure the maximum pos-
sible levels of safety.
The condition of the LPG system should be
checked regularly to guarantee safe driving
conditions ››› . These checks are included
in the Maintenance Programme. WARNING
● If there is a smell of gas or a suspected
leak, stop the vehicle immediately and switch
off the ignition. Open the doors to ventilate
the vehicle. Do not carry on driving! Take the
vehicle to a specialised workshop and have
the fault repaired.
● Immediately extinguish any cigarettes and
remove from the vehicle any objects which
might produce a spark or cause a fire, and
switch off immediately if gas is smelt or a
leak is detected.
● LPG tanks are subject to pressure and must
be checked regularly. The owner of the vehi-
cle must check that these services are per-
formed correctly. ●
When parking the vehicle in a closed area
(e.g. in a garage), make sure that there is ad-
equate ventilation, either natural or mechani-
cal, to neutralise the LPG in the event of a
leak. Note
For any fault in the LPG system, please refer
to the SEAT web page, which lists the work-
shops authorised to repair these faults. Working in the engine
compartment
Safety instructions on working in the
engine compartment Before starting any work on the engine or in
the engine compartment:
1. Switch off the engine and remove the key
from the ignition.
2. Apply the handbrake.
3. Move the gear lever to neutral or the selec- tor lever to position P.
4. Wait for the engine to cool down.
5. Keep children away from the vehicle.

Wheels and tyres General notes Avoiding damage
– If you have to drive over a kerb or similar
obstacle, drive very slowly and at a right
angle.
– Keep grease, oil and fuel off the tyres.
– Inspect the tyres regularly for damage
(cuts, cracks or blisters, etc.). Remove any
foreign objects embedded in the treads.
Storing tyres
– When you remove the tyres, mark them in
order to maintain the same direction of ro-
tation when they are installed again.
– When removed, the wheels and/or tyres
should be stored in a cool, dry and prefera-
bly dark location.
– Store tyres in a vertical position if they are
not fitted on wheel rims.
New tyres
New tyres must be run in ›››
page 130.
The tread depth of new tyres may vary, ac-
cording to the type and make of tyre and the
tread pattern. Concealed damage
Damage to tyres and rims is often not readily
visible. If you notice unusual vibrations or the
vehicle pulling to one side, this may indicate
that one of the tyres is damaged. They
should be checked immediately by a Techni-
cal Service.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the di-
rection of rotation on tyres with directional
tread. Always observe the direction of rota-
tion indicated when fitting the wheel. This
guarantees optimum grip and helps to avoid
aquaplaning, excessive noise and wear.
WARNING
● New tyres do not have maximum grip dur-
ing the first 500 km (300 miles). Drive partic-
ularly carefully to avoid possible accidents.
● Never drive with damaged tyres. This may
cause an accident.
● If you notice unusual vibrations or if the ve-
hicle pulls to one side when driving, stop the
vehicle immediately and check the tyres for
damage. Checking tyre pressure
The correct tyre pressure can be seen on the
sticker on the inside of the fuel tank flap.1. Read the required tyre inflation pressure
from the sticker. The values refer to Sum-
mer tyres. For winter tyres, you must add
0.2 bar (2.9 psi / 20 kPa) to the values
given for summer tyres.
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 impor-
tant at high speeds. The pressure 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 fuel tank flap.
The tyre pressure values given are for cold
tyres. Do not reduce the slightly raised pres-
sures of warm tyres ››› .
WARNING
● Check the tyre pressure at least once per
month. Checking the tyre pressure is very im-
portant. 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! » 175Technical specifications

Advice
For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption. 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 137.
– Continue driving carefully and slowly
(80 km/h [50 mph] maximum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (e.g. kerbs) or
potholes.
– Pay attention if the ESC/ASR activates of-
ten, 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 vehicle. The run-flat tyres have a tag on the side of
the tyre, with the description: “DSST”, “Eufo-
nia”, “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 cir-
cumstances are favourable (e.g. low load),
even more.
The damaged tyre should be changed as
soon as possible. The rim should be checked
in a specialised workshop to detect possible
damage and replace it if necessary. We rec-
ommend you contact your technical service.
If more than one tyre is being used under
emergency conditions, this reduces the dis-
tance that 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 condi-
tions
››› .
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 one of the tyres has been severely dam-
aged 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 dam-
age 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 over-
heating 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 con-
ditions. Please observe related legal require-
ments.

Emergencies
After inserting the sealant residue in the tyre,
you must again check the tyre pressure about
10 minutes after starting the engine.
You should only use the tire mobility set if
the vehicle is parked in a safe place, you are
familiar with the procedure and you have the
necessary tire mobility set! Otherwise, you
should seek professional assistance.
The tyre sealant must not be used in the
following cases:
● If the wheel rim has been damaged.
● In outside temperatures below -20 °C
(-4 °F).
● In the event of cuts or perforations in the
tyre greater than 4 mm.
● If you have been driving with very low pres-
sure or a completely flat tyre.
● If the sealant bottle has passed its use by
date. WARNING
Using the tyre mobility system can be dan-
gerous, especially when filling the tyre at the
roadside. Please observe the following rules
to minimise the risk of injury:
● Stop the vehicle safely as soon as possible.
Park it at a safe distance from surrounding
traffic to fill the tyre.
● Ensure the ground on which you park is flat
and solid. ●
All passengers and particularly children
must keep a safe distance from the work area.
● Turn on the hazard warning lights to warn
other road users.
● Use the tyre mobility system only if you are
familiar with the necessary procedures. Oth-
erwise, you should seek professional assis-
tance.
● The tyre mobility set is intended for tempo-
rary emergency use only until you can reach
the nearest specialised workshop.
● Replace the repaired tyre with the tire mo-
bility set as soon as possible.
● The sealant is a health hazard and must be
cleaned immediately if it comes into contact
with the skin.
● Always keep the tire mobility set out of the
reach of small children.
● Never use an equivalent jack, even if it has
been approved for your vehicle.
● Always stop the engine, apply the hand-
brake lever firmly and engage gear if using a
manual gearbox, in order to reduce the risk of
vehicle involuntary movement. WARNING
A tyre filled with sealant does not have the
same performance properties as a conven-
tional tyre.
● Never drive faster than 80 km/h (50 mph).
● Avoid heavy acceleration, hard braking and
fast cornering. ●
Drive only during 10 minutes at a maximum
speed of 80 km/h (50 mph) and subsequently
check the tyre. For the sake of the environment
Dispose of used or expired sealant observing
any legal requirements. Note
● A new bottle of sealant can be purchased at
SEAT dealerships.
● Take into account the separate instruction
manual from the tyre mobility set* manufac-
turer. Contents of the tyre mobility system*
