cause disruptions or faults in the automatic lighting system.•To avoid damage to the tail lights, the lights mounted on the tailgate go
off when the tailgate is opened (depending on the country).Daytime lights*
The daytime light reduces the risk of accidents by increasing
the visibility of the vehicle. The daytime running lights are
enabled automatically when the ignition is switched on. It is
automatically switched off when the side lights are turned on.Daytime lights (halogen lamps)
22)
The daytime lights increase road safety in vehicles fitted with halogen lamps.
These include the dipped, side and number plate lights.
The daytime lights are switched on each time the ignition is turned on if the
light setting is in position 0 or
!54/
. Depending upon the model, a control
lamp
 on the light control switch or the lighting up of the instrument panel
will indicate that the daytime lighting is on.
It is not possible to switch the daytime lights on or off. Please contact a
specialised workshop if you wish to deactivate the lights.
Daytime lights (bi-xenon lamps)
The daytime lights increase road safety in vehicles fitted with bi-xenon lamps.
The lights are built-in separately to the headlights and are switched on each
time the ignition is turned on if the light setting is in position 0 or
!54/
.Automatic control of the dipped light in combination with the daytime
lighting (bi-xenon headlamps)
If the dipped light control
and the daytime lighting are activated at the same
time, the dipped lights and the instrument panel lighting will automatically
come on as required (e.g. on entering a tunnel) and the daytime lights will go
off. When the automatic dipped light control switches off the dipped lights
(e.g. on coming out of the tunnel), the daytime lights come back on.
Activating the daytime lights
With the ignition switched off, move the turn signal and main beam lever
upwards and back (right turn signal and headlamp flash).
Switch on the ignition for 3 seconds while holding this position. The daytime
lights are activated and can be switched on.
Deactivating the daytime lights
With the ignition switched off, move the turn signal and main beam lever
upwards and back (left turn signal and headlamp flash) and hold in this posi-
tion.
Switch on the ignition for 3 seconds while holding this position. The daytime
lights are deactivated and cannot be switched on.

tight spaces, depending on the equipment fitted on your vehicle.
The SEAT Parking System* gives an acoustic warning if there are any obsta-
cles behind your vehicle.
When you are parking, the SEAT Parking System Plus* warns you acoustically
and optically
23) about obstacles “in front of” and “behind” the vehicle.
Note
To ensure the acoustic parking aid works properly, the sensors must be kept
clean and free of snow and ice.
SEAT Parking System: Description
The Parking System is an acoustic parking aid.Sensors are located in the rear bumper. When the sensors detect an obstacle,
you are alerted by acoustic signals. The measuring range of the sensors starts
at approximately:
The acoustic signals 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. Do not drive on!
The volume of the warning beeps will be gradually reduced after about four
seconds if the vehicle remains at a constant distance from a detected
obstacle (it does not affect the permanent acoustic signal).
The parking aid is switched on automatically when reverse gear is engaged.
You will hear a brief confirmation tone.
WARNING
•The parking aid is not a replacement for driver awareness. The driver is
personally responsible for safe parking and other manoeuvres.•The sensors have blind spots in which obstacles are not registered.
Always look out for small children and animals because the system will not
always detect them. Always pay attention when reversing to avoid acci-
dents.•Always keep a close eye on the area around the vehicle and make full
use of the rear view mirrors.

When the TCS is off, the warning lamp is lit. The TCS should normally
be left on. Only in exceptional circumstances, when the slipping of the wheels
is required, should it be disconnected, for example
•With compact temporary spare wheel.•When using the snow chains.•When driving in deep snow or on loose surfaces•When the vehicle is bogged-down, to free it by rocking.
The TCS should be switched on again as soon as possible.WARNING
•It must be remembered that TCS cannot 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 situation. Do not let the extra safety afforded by TCS tempt you
into taking any risks when driving, this can cause accidents.Caution
•In order to ensure that TCS function correctly, all four wheels must be
fitted with the same tyres. Any differences in the rolling radius of the tyres can
cause the system to reduce engine power when this is not desired.•Modifications to the vehicle (e.g. to the engine, the brake system, running
gear or any components affecting the wheels and tyres) could affect the effi-
ciency of the ABS and TCS.
XDS*
Driveshaft differentialWhen taking a bend, the driveshaft differential mechanism allows the outer
wheel to turn at a higher speed than the inner wheel. In this way, the wheel
that is turning faster (outer 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.
By using the ESP sensors and signals, the XDS system is able to detect and
correct this effect.
Through the ESP, the XDS brakes the inner wheel, thereby counteracting the
excess drive torque in this wheel. This means that the driver’s desired trajec-
tory is much more precise,
The XDS system operates in combination with the ESP and is always active,
even when the traction control, TCS, is disconnected.Electronic Stability Programme (ESP)*General notes
The Electronic Stability Programme increases the vehicle’s
stability on the road.The Electronic Stability Programme helps reduce the danger of skidding.
The Electronic Stability Programme (ESP) consists of ABS, EDL, TCS and

Intelligent technology
200Electronic Stability Programme (ESP)*
ESP reduces the danger of skidding by braking the wheels individually.
The system uses the steering wheel angle and road speed to calculate the
changes of direction desired by the driver, and constantly compares them
with the actual behaviour of the vehicle. If the desired course is not being
maintained (for instance, if the vehicle is starting to skid), then the ESP
compensates automatically by braking the appropriate wheel.
The forces acting on the braked wheel bring the vehicle back to a stable
condition. If the vehicle tends to oversteer, the system will act on the front
wheel on the outside of the turn.
Steering manoeuvre recommendations
This is a complementary safety function included in the ESP This function aids
the driver to better stabilize the vehicle in a critical situation. For example, in
case of sudden braking surface with varied adherence, the vehicle will tend
to destabilise its trajectory to the right or to the left. In this case the ESP
recognizes the situation and helps the driver with a counter steering
manoeuvre from the power steering.
This function simply provides the driver with a recommended manoeuvre in
critical situations.
The vehicle does not steer itself with this function, the driver has full control
of the vehicle at all times.
WARNING
•It must be remembered that ESP cannot 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 situation. Do not let the extra safety afforded by ESP tempt you
into taking any risks when driving, as this can cause accidents.
Caution
•In order to ensure that ESP functions correctly, all four wheels must be
fitted with the same tyres. Any differences in the rolling radius of the tyres can
cause the system to reduce engine power when this is not desired.•Modifications to the vehicle (e.g. to the engine, the brake system, running
gear or any components affecting the wheels and tyres) could affect the effi-
ciency of the ABS, EDL, ESP and TCS.Anti-lock brake system (ABS)The anti-lock brake system prevents the wheels locking during braking
⇒ page 198.Electronic differential lock (EDL)*
The electronic differential lock helps prevent the loss of trac-
tion caused if one of the driven wheels starts spinning.EDL helps the vehicle to start moving, accelerate and climb a gradient in slip-
pery conditions where this may otherwise be difficult or even impossible.
The system will control the revolutions of the drive wheels using the ABS
sensors (in case of an EDL fault the warning lamp for ABS lights up)
⇒ page 84.
At speeds of up to approximately 80 km/h, it is able to balance out differ-
ences in the speed of the driven wheels of approximately 100 rpm caused by
a slippery road surface on one side of the vehicle. It does this by braking the
wheel which has lost traction and distributing more driving force to the other
driven wheel via the differential.

2. The tyre pressures should only be checked when the tyres are cold. The slightly raised pressu res of warm tyres must not be
reduced.
3. Adjust the tyre pressure to the load you are carrying.Tyre pressure
The correct tyre pressure is especially important 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
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 uses the speed sensors of the ABS wheels. It operates by
analysing the speed and frequency spectrum of each wheel.
For optimum performance, use genuine SEAT tyres. In addition, check and
adjust tyre pressures regularly.
Whenever the tyre pressures are changed or one or more tyres are changed,
the system should be Reset by pressing the SET switch on the centre console.
The system warns the driver in the event of a loss of pressure by means of
symbols and messages in the instrument panel display. The system uses ESP
⇒ page 199.
Note that tyre pressure also depends on tyre temperature. Tyre pressure
increases 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
accordingly. 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!
