Differential lock fault (EDL)*
EDL operates along with the ABS in vehicles equipped with
an Electronic Stability Programme (ESP)*
A malfunction in the EDL is indicated by the ABS warning lamp . Take the
vehicle to a specialised workshop as soon as possible. For further informa-
tion on the EDL see ⇒ page 170, Electronic differential lock (EDL)*. 
Traction control system (TCS)*  / 
The traction control system prevents the driven wheels from
spinning when the vehicle is accelerating
There are two warning lamps for the traction control system:  and . Both
warning lamps light up together when the ignition is switched on and
should turn off after approximately 2 seconds. This is the time taken for the
function check.
The  lamp has the following function:
● It flashes when the TCS is on, and the vehicle is moving.
If the system is deactivated or if it has any fault, the warning lamp will re-
main lit. It will also come on if a fault should occur in the ABS because the
TCS operates in conjunction with the ABS. For further information, see
⇒  page 167, Brakes
The  lamp provides information about the disconnection status of the
system:
● It stays lit when the TCS is disconnected after pressing the TCS OFF
switch.
By pressing again, TCS function is reactivated and the warning lamp switch-
ed off. Electronic Stability Programme (ESP)*  / 
There are two warning lamps for the electronic stability pro-
gramme. The  lamp provides information concerning the
function and the
 provides information on the disconnec-
tion status
Both warning lamps light up together when the ignition is switched on and
should turn off after approximately 2 seconds. This is the time taken for the
function check.
This programme includes the ABS, EDL and TCS. It also includes emergency
braking assistance (BAS).
The warning lamp  has the following functions:
● It flashes when the TCS/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
functional.
The  lamp provides information about the disconnection status of the
system:
● It stays lit when the TCS is disconnected after pressing the  switch.

Safety Electronic Stability Programme (ESP)*
ESP helps make driving safer in certain situations.
Fig. 106 Detailed view of
the centre console: ESP
button.
The Electronic Stability Programme (ESP) contains the electronic differential
lock (EDL) and the traction control system (TCS). The ESP function works to-
gether with the ABS. Both warning lamps will light up if the ESP or ABS sys-
tems 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.
WARNING
● The Electronic Stability Programme (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.
● Please refer to the corresponding warning notes on ESP in
⇒ page 167, Intelligent technology.

Intelligent technology
TCS helps the vehicle to start moving, accelerate and climb a gradient in
slippery conditions where this may otherwise be difficult or even impossi-
ble.
The TCS is switched on automatically when the engine is started. If necessa-
ry, it may be turned on or off by briefly pushing the ESP button on the centre
console.
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, can they be disconnected using the ESP button, 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 fit-
ted 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, run-
ning gear or any components affecting the wheels and tyres) could affect
the efficiency of the ABS and TCS. XDS*
Driveshaft differential
When 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 under-
steer 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 tra-
jectory 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 and TCS.
Safety FirstOperating InstructionsPractical TipsTechnical Specifications

170Intelligent technology
Electronic 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.
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, run-
ning gear or any components affecting the wheels and tyres) could affect
the efficiency of the ABS, EDL, ESP and TCS. Anti-lock brake system (ABS)
The anti-lock brake system prevents the wheels locking during braking
⇒ page 168.

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
slippery conditions where this may otherwise be difficult or even impossi-
ble.
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 69.
At speeds of up to approximately 80 km/h, it is able to balance out differen-
ces 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 oth-
er 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 con-
tinue to function normally without EDL. For this reason, the driver is not in-
formed that the EDL has been switched off.
The EDL will switch on again automatically when the brake has cooled
down. 
