64•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
J. Take the
vehicle to a specialised workshop as soon as possible. For further informa-
tion on the EDL see ⇒page 162, “Electronic differential lock (EDL)*”.
Traction control system (TCS)*
/l
The traction control system prevents the driven wheels from
spinning when the vehicle is acceleratingThere are two warning lamps for the traction control system:
 and
l. The
warning lamp
 lights up when the ignition is switched on and should turn
off after 2 seconds, which 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 remain
li t . I t will als o co m e o n i f a fa ul t s hould occur in the A B S b e caus e t he TCS o pe r -
ates in conjunction with the ABS. For further information, see ⇒page 159,
“Brakes” The
l 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 switched
off.Electronic Stability Programme (ESP)*
/ l
There are two warning lamps for the electronic stability
programme. The
 lamp provides information concerning
the function and the l provides information on the discon-
nection status
The warning lamp
 lights up when the ignition is switched on and should
turn off after 2 seconds, which is the time taken for the function check.
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 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 func-
tional.

66•The tyre structure is damaged.•The vehicle is unbalanced because of a load.•The wheels of one axle are under more pressure (for example, driving with
a trailer or on extreme slopes).•The vehicle is fitted with snow chains.•The temporary spare wheel is fitted.•The wheel on one axle is changed.
Tyre pressure adjustment
Following the modification to tyre pressure or changing one or more wheels,
the button ⇒page 65, fig. 38 must be kept pressed while the ignition is on
until an acoustic signal is heard.
If the wheels are under excessive load (for example, driving with a trailer or
heavy load), the tyre pressure must be increased to the recommended value
for a full load (see the sticker on the inside of the fuel flap). If the tyre m onitor
system button is pressed down, the new tyre pressures are confirmed.
The tyre pressure warning lamp
~ lights up
If the tyre pressure of a wheel is much lower than the value set by the driver,
then the tyre pressure warning lamp ⇒ will light up.
WARNING
•When the tyre pressure warning lamp lights up, reduce speed immedi-
ately and avoid any sudden manoeuvre or braking. Stop when possible,
and check the tyre pressure and status.•The driver is responsible for maintaining correct tyre pressures. For this
reason, tyre pressure must be regularly checked.•Under certain circumstances (for example, when driving in a sportslike
manner, in winter conditions or on a dirt track) the tyre warning lamp may
light up or function incorrectly.
Note
If the battery is disconnected, the yellow warning lamp
~ lights up after
turning the ignition on. This should turn off after a brief journey.

Driving
136SafetyElectronic Stability 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.
WARNING
•The Electronic Stability Programme (ESP) cannot defy the laws of
physics. This should be kept in mi nd, 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 159,
“Intelligent technology”.

Reverse gear
The distance warning will begin as soon as an obstacle is detected by the
system. The frequency of the bleeps emitted by the system will increase
rapidly as the vehicle approaches the obstacle.
Within a short distance of about 30cm, a continuous signal sounds (stop
signal). The driver should not reverse any further.
Models with a factory-fitted towing bracket: When the vehicle is less than
0.35 m away from the obstacle the warning tone will sound continuously. The
driver should then not reverse any further.
The warning tone decreases by 30% after 3 seconds from the start of the
system.
Provided that it is not in continuous mode, the tone on the parking aid system
stops when it detects a wall parallel to the vehicle.
Trailer towing
For vehicles factory-fitted with a towing bar, the parking aid system will not
be activated by the engagement of the reverse gear when pulling a trailer, as
the trailer’s electric connector will be plugged into the vehicle.
Possible faults
If a continuous beep sounds for some seconds when the reverse gear is
engaged, this indicates that there is a fault in the parking aid system.
If the fault continues until the ignition is turned off, the acoustic signal
warning of the fault will not be emitted every time the system is reactivated
(by engaging the reverse gear). Thus, the system ready indication will not
sound either. Have the fault repaired by an Authorised Service Centre as soon
as possible.
If there is no ready signal or no acoustic warning signal, then the parking aid
loudspeaker is faulty and may not warn of obstacles.
To ensure that the system works properly, the sensors must be kept clean and
free of ice and snow.
WARNING
•The sensors have blind spots in which obstacles may not be detected.•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.•The parking aid is not a replacement for driver awareness. The driver
must take full responsibility for parking and other manoeuvres.Caution
•Please note that low obstacles detected by the system may no longer be
registered by the sensors as the car moves closer, so the system will not give
any further warning. Certain kinds of obstacles (such as wire fences, chains,
thin posts or trailer draw bars, high kerbs or painted railings etc) may not
always be detected by the system, so there is a risk of damaging the vehicle
in such cases.•In some cases, obstacles with uniform edges and bumps may not be
detected immediately by the system due to their geometry. Take special care
of this type of obstacle (corners, rectangular objects, etc.), as they can cause
damage to the vehicle.•Be especially careful when manoeuvring into a corner between two

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
l 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
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.

162Electronic 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

•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 160.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 63.
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.
