2008 Seat Leon 5D differential

Cockpit
82Differential lock fault (EDL)*
EDL operates along with the ABS in vehicles equipped with an
Electronic Stabilisation Program (ESP)*A malfunction in the EDL is indicated by the ABS warning lamp
. Please
take the vehicle to a qualified workshop as soon as possible. For further infor-
mation on the EDL ⇒page 178, “Electronic differential lock (EDL)*”.
Traction control system (TCS)*
The traction control system prevents the driven wheels from
spinning when the vehicle is acceleratingThe warning lamp lights up when the ignition is switched on and should turn
out after about 2 seconds.
When the TCS is operating while drivi ng, the warning lamp flashes. If the
system is deactivated or if there is any fault in the same, the warning lamp will
remain lit.
It will also come on if a fault should occur in the ABS because the TCS oper-
ates in conjunction with the ABS. For further information, see ⇒page 175,
“Brakes”.
If the TCS button is activated, the TC S function deactivates and the warning
lamp remains lit.
By pressing again, TCS function is reactivated and the warning lamp switched
off.
Operating the foot brake

The footbrake must be depressed when this warning lamp lights up. This is
necessary when the automatic gearbox* selector lever is moved out of the
positions P or N.Electronic immobiliser* “Safe”
This warning lamp flashes if an unauthorised key is used.Inside the key there is a chip that deac tivates 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 instrument panel displays the following message
17): SAFE . The vehicle
cannot be used in that case ⇒page 157.
The engine can, however, be started if the appropriate coded SEAT genuine
key is used.
Note
A perfect operation of the vehicle is ensured if genuine SEAT keys are used.17)Depending on the version of the model.

Practical tips
Te c h n i c a l D a t a
•
Adjust the driver seat or steering wheel so that there is a distance of at
least 25 cm between the steering wheel and your chest ⇒page 154,
fig. 116 . If you fail to observe the minimum distance, the airbag will not
protect you. Risk of fatal injury.
•
If your physical constitution does not allow you to mantain the
minimum distance of 25 cm, contact an Authorised Service Centre. The
Authorised Service Centre will help you to decide if special specific modifi-
cations are necessary.
•
If you adjust the steering wheel so th at it points towards your face, the
driver airbag will not protect you prop erly in the event of an accident. Make
sure that the steering wheel points towards your chest.
•
When driving, always hold the steering wheel with both hands on the
outside of the ring at the 9 o'clock and 3 o'clock positions. Never hold the
steering wheel at the 12 o'clock position, or in any other manner (e.g. in
the centre of the steering wheel, or on the inside of the rim). In such cases,
you could receive severe injuries to the arms, hands and head.
SafetyElectronic stabilisation programme (ESP)*
ESP helps make driving safer in certain situations.The Electronic Stabilisation Program (ESP ) contains the electronic differential
lock (EDL) and the traction control system (TCS). The ESP function works
together with the ABS. Both warning lamps will light up if the ESP or ABS
systems are faulty.
The ESP is started automatically when the engine is started.
The ESP is always active, and cannot be switched off. With the ESP switch it is
only possible to switch TCS off.
The TCS can be deactivated when in cases where wheel sliding is desirable.
For example:•
When driving with snow chains,

•
With compact temporary spare wheel.
•
When using the snow chains.
•
When driving in deep snow or on soft terrain.
•
When the vehicle is bogged-down, to free it by “rocking.”
The TCS should be switched on again afterwards as soon as possible.
WARNING
•
It must be remembered that TCS cann ot defy the laws of physics. This
should be kept in mind, particular ly 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 wh eels 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 vehi cle. If the desired course is not being

178maintained (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 driv ing, 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 176.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 th e warning lamp for ABS lights up)
⇒ page 77.
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.
