Technical Data
The warning lamp should light up for a few seconds when the ignition is
switched on. It should go out once the engine is started.
If the battery is disconnected, the indicator remains lit, even with the engine
running. The warning light only goes off after a distance of approx. 50 m.
There is a fault in the electromechanical steering system if the lamp does not
go out or lights up whilst the vehicle is in motion. The indicator may appear
in two different colours to indicate faults. If it lights yellow, this indicates a
minor fault. If it lights red, seek workshop assistance immediately, if no
assistance is available stop driving. Stop the vehicle and seek technical
assistance. The power steering does not work if the battery is flat or if the
engine is off (for example, for towing). You should take into account that you
will need considerably more power than normal to steer the vehicle if the
steering assistance is reduced or has failed completely.
For those vehicles fitted with ESP* the function “Recommended steering
manoeuvre” is included. See
⇒page 183.
Emission control system*

 is lit:
If a fault has developed during driving which has reduced the quality of the
exhaust gas (e.g. lambda probe fault). Reduce speed and drive carefully to
the nearest qualified workshop to have the engine checked.

Electronic stabilisation programme (ESP)*

This warning lamp monitors the electronic stabilisation
programme.
This programme includes the ABS, EDL and TCS. This also includes the brake
assist system (BAS), automatic cleaning of the brake discs and the trailer
stability programme (TSP).
The warning lamp
 has the following functions:
•It will light for about 2 seconds when the ignition is switched on while a
test of the function is carried out.•It flashes when the ESP is activated when driving.•It will light up continuously if there is a malfunction in the ESP.•It will also come on if a fault should occur in the ABS because the ESP
operates in conjunction with the ABS.
If the ESP warning lamp
 lights up and stays on after the engine is started,
this may mean that the control system has temporarily switched off the ESP.
In this case the ESP can be reactivated by switching the ignition off and then
on again. If the warning lamp goes out, this means the system is fully func-
tional.
If the ESP button is activated, the TCS function deactivates and the warning
lamp flashes.

Driving
158Starting
The engine is started when the key is in this position. Electrical components
with a high power consumption are switched off temporarily.
Every time the vehicle is started again, the ignition key must be turned to
position . The repetitive start prevention lock of the ignition prevents
possible damage to the starter motor if the engine is already running.
WARNING
•The ignition key must NOT be removed from the lock until the vehicle
comes to a standstill. Otherwise, the steering could be immediately
blocked- Risk of accident!•Always remove the key from the ignition lock when leaving the vehicle,
even for a short period. This is especially important if children or disabled
people are left alone in the vehicle. They could accidentally start the
engine or work electrical equipment such as the electric windows, conse-
quently resulting in an accident.•Unsupervised use of the keys could start the engine or any electrical
system, such as the electric window. This could result in serious injury.Caution
The starter motor will only work when the engine is stopped (ignition key
position ).Electronic immobiliser
The immobiliser prevents unauthorised persons from driving
the vehicle.Inside the key there is a chip that deactivates the electronic immobiliser auto-
matically when the key is inserted into the ignition. The immobiliser will be activated again automatically as soon as you pull the
key out of the ignition lock.
The engine can only be started using a genuine SEAT key with its correct code.
Note
A perfect operation of the vehicle is ensured if genuine SEAT keys are used.Starting and stopping the engineStarting petrol engines
The engine can only be started using a genuine SEAT key with
its correct code.– Move the gear lever to the neutral position and depress the
clutch pedal thoroughly and hold it in this position for the starter
to turn the engine on.
– Turn the ignition key to the starting position ⇒page 157.
– Le t go o f t he ign itio n key as so o n as t he eng in e sta r ts; t he sta r te r motor must not run on with the engine.After starting a very hot engine, you may need to slightly press down the
accelerator.
When starting a very cold engine, it may be a little noisy for the first few
seconds until oil pressure has built up in the hydraulic valve compensators.
This is quite normal, and no cause for concern.

engines.•The battery charge must not be low for the next start.•The battery temperature must be between -1°C and 55°C.•The parking assistant, Park Assist* must not be activated.
Interrupting the Start-Stop function
In the following situations, the Start-Stop function will be interrupted and the
engine will automatically start:•The vehicle is moving.•The brake pedal is pressed several times in a row.•The battery has been discharged excessively.•The Start-Stop System has been manually deactivated.•The windscreen de-mist function is turned on.•The temperature of the passenger compartment exceeds the convenience
limits (button ⇒page 152, fig. 114 should be selected).•If in an increase in airflow ⇒page 152, fig. 114 is required for more
than three presses.•Either of the temperature settings, HI or LO, is selected.•The engine coolant temperature is insufficient.•The alternator is faulty, for example the V-belt has ruptured.•If any of the conditions described in the previous section are not fulfilled.
WARNING
Never allow the vehicle to move with the engine off for any reason. You
could lose control of your vehicle. This could cause an accident and serious
injury.•The brake servo does not work when the engine is not running. You
need more force to stop the vehicle.•Power assisted steering does not work when the engine is not running.
That is why it is much more difficult to turn the steering wheel.Note
•For vehicles with the Start-Stop function and a manual gearbox, when the
engine is started, the clutch must be pressed.•When the conditions for the Start-Stop function are not fulfilled, the dash
panel displays the Start-Stop indicator dimmed.•The vehicle can be restarted by rotating the steering wheel three times,
that is, more than 270°.

the motorway or in the city.
Selecting the manual programme (tiptronic)
This programme allows driving similar to a manual gearbox.
This programme may be accessed using the selector lever or from the
steering wheel controls when this option is fitted
⇒page 169.
Selector lever locking
The selector lever lock prevents gears from being engaged
inadvertently, which would cause the vehicle to move.Releasing the selector lever lock
– Start the vehicle. – Press and release the brake pedal, at the same time press the
button on the selector lever.
The lock is only activated when the vehicle is stopped or at a speed of less
than 5 km/h. At higher speeds, the lock is automatically released in position
N.
For rapid changes of position (e.g. from R to D) the lever will not lock. If the
lever remains in the position N more than one second then it is locked. With
the automatic lock, the lever is prevented passing from P and N to any other
gear without first pressing the brake pedal.
The selector lever must be put in the position P in order to remove the key.Driving with an automatic gearbox* / DSG automatic gearbox*
The drive and reverse gears are automatically engaged.

•If you must stop on a hill, always hold the vehicle using the footbrake
to avoid rolling back.•The footbrake must not be held for a long period of time, not even
lightly; continuous braking will cause overheating of the brakes and a
reduction or even a loss of braking power and a significant increase in
braking distances.•Never allow the vehicle to coast down a gradient with the selector lever
in positions N or D, even when the engine is not running. For descents, the
use of the Tiptronic programme is recommended to keep the speed
reduced.Caution
•Never use the automatic gearbox to hold the vehicle stationary on a hill,
even for short periods, as this may overheat the gearbox and cause damage.
Apply the handbrake or depress the foot brake to hold the vehicle in position.•If the vehicle is allowed to roll with the engine stopped but the selector in
position N then the gearbox may be damaged because it will not be
lubricated.

The TCS should be switched on again afterwards 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
which is turning faster (outer wheel) receives less drive torque than the inner
wheel. This may mean that in certain situations the torque provided to the inner wheel is too high, causing the wheels to spin. On the other hand, the
outer wheel receives a lower drive torque than it could transmit. This causes
an overall loss of lateral grip on the front shaft, resulting in understeering or
“lengthening” of the path.
The XDS system is able, using the ESP sensors and signals, to detect and
correct this effect.
The XDS, via the ESP, brakes the inner wheel thus counteracting the excess
drive torque in this wheel. This means that the path requested by the driver
is more precise,
The XDS system operates in combination with the ESP and is always active,
even when the traction control, TCS, is disconnected.
Electronic stabilisation programme (ESP)*General notes
The electronic stabilisation programme increases the
vehicle's stability on the road.The electronic stabilisation programme helps to reduce the danger of skid-
ding.
The electronic stabilisation programme (ESP) consists of
ABS, EDL, TCS and
Steering manoeuvre recommendations.
Electronic Stabilising Program (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

184maintained (for instance, if the car is starting to skid), then the ESP compen-
sates 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 destabilize its trajectory to the right to 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 doesn't 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, 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 182.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 79.
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.
To prevent the disc brake of the braking wheel from overheating, the EDL cuts
out automatically if subjected to excessive loads. The vehicle will continue to
function normally without EDL. For this reason, the driver is not informed that
the EDL has been switched off.
The EDL will switch on again automatically when the brake has cooled down.
