60•If the brake fluid level is correct, the fault in the brake system may have
been caused by a failure of the ABS system. This could cause the rear
wheels to lock quickly when you brake. This could cause the rear to break
away. Risk of skidding. Stop the vehicle and seek technical assistance.
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
. Please
take the vehicle to a qualified workshop as soon as possible. For further infor-
mation on the EDL see ⇒page 154, “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 driving, its warning lamp flashes rapidly. If
there is a fault in the system, the warning lamp is lit permanently.
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 151,
“Brakes” If ESP* button is activated, TCS function deactivates and the warning lamp
flashes slowly. By pressing again, TCS function is reactivated and the warning
lamp switched off.
Electronic Stability Programme (ESP)*

This warning lamp monitors the Electronic Stability
Programme.This programme includes the ABS, EDL and TCS.
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 rapidly when the ESP is activated while 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.

SafetyElectronic Stabilit y Programme (ESP)*
ESP helps make driving safer in certain situations.The Electronic Stability Programme (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.
When does the warning light switch on or flash ?•On switching the ignition on, it lights up for about two seconds to carry
out a function control.
•The warning lamp will start flashing when the vehicle is moving if the ESP
or the TCS is activated. The warning lamp will light up slowly if the TCS is
switched off.•It will light up continuously if there is a malfunction in the ESP.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, this can cause accidents.•Please refer to the corresponding warning notes on ESP in ⇒page 151,
“Intelligent technology”.

it may be turned on or off by briefly pushing the ESP button on the centre
console.
When the TCS is switched off, the warning lamp flashes slowly. The TCS
should normally be left switched on at all times. Only in exceptional circum-
stances, when the slipping of the wheels is required, can they be discon-
nected 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 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
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 and TCS.

154Electronic 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 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.
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 152.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 59.
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.
WARNING
•When accelerating on a slippery surface, for example on ice and snow,
press the accelerator carefully. Despite EDL, the driven wheels may start to
spin. This could impair the vehicle's stability.
