Driving
WARNING
● If you do not start the vehicle immediately after taking your foot off
the brake pedal, the vehicle may start to roll back under certain condi-
tions. Depress the brake pedal or use the handbrake immediately.
● If the engine stalls, depress the brake pedal or use the handbrake im-
mediately.
● When following a line of traffic uphill, if you want to prevent the vehi-
cle from rolling back accidentally when starting off, hold the brake pedal
down for a few seconds before starting off.
Note
The Official Service or a specialised workshop can tell you if your vehicle is
equipped with this system. 
Acoustic parking aid system* Rear parking aid
The parking aid system will use an audible warning to indi-
cate of the approach of any object towards the rear of the ve-
hicle. Description
The acoustic parking aid system will measure the distance between the rear
of the vehicle and any possible obstacle using four ultrasonic sensors loca-
ted on the rear bumper. The measuring range of the sensors starts approxi-
mately and depending on the nature of the obstacle at a distance of:
● side of the rear bumper: 0.6 m
● middle of the rear bumper: 1.6 m Activation
The system is activated by engagement of the reverse gear. A brief audible
warning confirms the activation and correct function of the system.
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 rap-
idly 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 sys-
tem 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 en-
gaged, this indicates that there is a fault in the parking aid system.
If the fault continues until the ignition is turned off, the audible warning of
the fault will not be emitted every time the system is reactivated (by engag-
ing the reverse gear). Thus, the system ready indication will not sound ei-
ther. Have the fault repaired by a Technical Service 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.

Safety FirstOperating InstructionsPractical TipsTechnical Specifications

164Driving
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 accidents.
● 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 de-
tected 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 per-
pendicular walls. Carefully watch the approach of the wall to the side of the
vehicle (using the mirrors).
● The parking aid system does not replace use of the mirrors for manoeu-
vres.
● External ultra-sonic sources (pneumatic drills, construction machinery,
other vehicles with PDC) may interfere with the operation of the system.
● Periodic cleaning of the sensors, take care not to damage or scratch
them. When cleaning with high pressure washers or steam cleaners, the
sensors should be sprayed for only a very short period and from a distance
of more than 10 cm. Cruise speed* (Cruise control system)
Description
The cruise control system is able to maintain the set speed
in the range of 30 km/h (20 mph) to 180 km/h (110 mph).
Once the speed setting has been saved, you may take your foot off the ac-
celerator.
WARNING
It could be dangerous to use the cruise control system if it is not possible
to drive at constant speed.
● Do not use the cruise control system when driving in dense traffic, on
roads with lots of bends or on roads with poor conditions (with ice, slip-
pery surfaces, loose grit or gravel), as this could cause an accident.
● Always switch the cruise control system off after using it in order to
avoid an involuntary use.
● It is dangerous to use a set speed which is too high for the current
road, traffic or weather conditions. Risk of accident.
Note
The cruise control cannot maintain a constant speed when descending
downhill. The vehicle will accelerate due to its own weight. Use the foot
brake to slow the vehicle. 

166Driving
Adjusting set speed*
The speed can be altered without touching the accelerator or
the brake.

trol
Setting a higher speed
– Press the upper part RES of the rocker switch ⇒ Fig. 122 B
to
increase the speed. The vehicle will continue to accelerate as
long as you keep the rocker switch pressed. When you release
the switch, the new speed is stored.
Setting a lower speed
– Press the lower part SET– of the rocker switch B
to reduce the
speed. The vehicle will automatically reduce its speed for as
long as you keep the switch pressed. When you release the
switch, the new speed is stored.
When you increase speed with the accelerator and then release the pedal,
the system will automatically restore the set speed. This will not be the
case, however, if the vehicle speed is more than 10 km/h (mph) higher than the stored speed for longer than 5 minutes. The speed will have to be stor-
ed again.
Cruise control is switched off if you reduce speed by depressing the brake
pedal. Reactivate the control by pressing once on the upper part of the rock-
er switch RES+ ⇒ Fig. 122

Brakes Brake servo
The brake servo increases the pressure you apply to the brake pedal. It
works only when the engine is running .
If the brake servo is not functioning due to a malfunction, or if the vehicle
has to be towed, you will have to press the brake pedal considerably harder
to make up for the lack of servo assistance.
WARNING
The braking distance can also be affected by external factors.
● Never let the vehicle coast with the engine switched off. Failure to do
so could result in an accident. The braking distance is increased consid-
erably when the brake servo is not active.
● If the brake servo is not working, for example when the vehicle is be-
ing towed, you will have to press the brake pedal considerably harder
than normal.
 Hydraulic Brake Assist (HBA)*
The function (Hydraulic Brake Assist HBA) is only included in
vehicles with ESC.
In an emergency, most drivers brake in time, but not with maximum force.
This results in unnecessarily long braking distances.
This is when the brake assist system comes into action. When pressing the
brake pedal rapidly, the assistant interprets it as an emergency. It then very
quickly builds up the full brake pressure so that the ABS can be activated
more quickly and efficiently, thus reducing the braking distance.
Do not reduce the pressure on the brake pedal. The brake assist system
switches off automatically as soon as you release the brake.
Automatic hazard warning lights activation
The brake lights flash automatically to indicate that the vehicle is braking
suddenly or in an emergency situation. If the emergency braking continues
until the vehicle comes to a standstill, the hazard warning lights will then
come on and the brake lights will remain on permanently from that moment.
The warning lights will automatically switch off when the vehicle begins to
move again or when the "warning" light button is pressed. 

WARNING
● The risk of accident is higher if you drive too fast, if you do not keep
your distance to the vehicle in front, and when the road surface is slip-
pery or wet. The increased accident risk cannot be reduced by the brake
assist system.
● The brake assist system cannot defy the laws of physics. Slippery
and wet roads are dangerous even with the brake assist system! There-
fore, it is essential that you adjust your speed to suit the road and traffic
conditions. Do not let the extra safety features tempt you into taking any
risks when driving.

Anti-lock brake system and traction control
ABS Anti-lock brake system (ABS)
The anti-lock brake system prevents the wheels locking dur-
ing braking.
The anti-lock brake system (ABS) is an important part of the vehicle's active
safety system.
How the ABS works
If one of the wheels is turns too slowly in relation to the road speed, and is
close to locking, the system will reduce the braking pressure for this wheel.
The driver is made aware of this control process by a pulsating of the brake
pedal and audible noise. This is a deliberate warning to the driver that one
or more of the wheels is tending to lock and the ABS control function has
intervened. In this situation it is important to keep the brake pedal fully de-
pressed so the ABS can regulate the brake application. Do not “pump”. If you brake hard on a slippery road surface, the best possible control is re-
tained as the wheels do not lock.
However, ABS will not necessarily guarantee shorter braking distances in
all
conditions. The braking distance could even be longer if you brake on gravel
or on fresh snow covering a slippery surface.
WARNING
● The anti-lock brake system cannot defy the laws of physics. Slippery
and wet roads are dangerous even with ABS! If you notice that the ABS is
working (to counteract locked wheels under braking), you should reduce
speed immediately to suit the road and traffic conditions. Do not let the
extra safety features tempt you into taking any risks when driving.
● The effectiveness of ABS is also determined by the tyres fitted
⇒ page 216.
● If the running gear or brake system is modified, the effectiveness of
the ABS could be severely limited.

Drive wheel traction control system (ASR)*
The traction control system prevents the driven wheels from
spinning when the vehicle is accelerating. The system al-
ways includes ABS
Description and operation of the traction control system during
acceleration (ASR
On front-wheel drive vehicles, the ASR system intervenes, reducing engine
power and preventing the driven wheels from slipping during acceleration.
The system works in the entire speed range in conjunction with ABS. If a
failure occurs in the ABS, the ASR will also stop working. 
Safety FirstOperating InstructionsPractical TipsTechnical Specifications

170Intelligent technology
The ASR helps the car to start moving, accelerate and climb a gradient in
slippery conditions, where this may otherwise be difficult or even impossi-
ble.
The ASR automatically switches on when the engine is started. If necessary,
it may be turned on or off by briefly pushing the ESC button on the centre
console.
When the ASR is off, the warning lamp  is lit. The ASR should normally be
left on. Only in exceptional circumstances, when the slipping of the wheels
is required, can they be disconnected using the ESC 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 ASR should be switched on again as soon as possible.
WARNING
● Remember that not even the ASR can 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. The greater safety provided by the ASR should not
encourage you to run any risks.
CAUTION
● To ensure that the ASR works correctly, identical tyres should be fitted
on all four wheels. Any differences in the rolling radius of the tyres can
cause the system to reduce engine power when this is not desired.
● Any modifications made to the vehicle (for example, to the engine,
brake system, running gear or to the combination of wheels and tyres) may
affect the operation of the ABS and ASR. 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.
The XDS system can detect and correct this effect via the sensors and sig-
nals of the ESC.
Via the ESC, the XDS will brake the inside wheel and counter the excess
driving torque of that wheel. This means that the driver's desired trajectory
is much more precise,
The XDS system works in combination with the ESC and is always active,
even when the ASR traction control is disconnected.

Electronic Stability Control (ESC)*
General notes
The Electronic Stability Control increases the vehicle's stabil-
ity on the road. The Electronic Stability Control helps reduce the danger of skidding.
The Electronic Stability Control (ESC) includes the systems ABS, EDL and
ASR 

171
Intelligent technology
Electronic Stability Control (ESC)*
The ESC reduces the risk 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. When irregularities occur, for exam-
ple, if the vehicle begins to skid, the ESC brakes the appropriate wheel au-
tomatically.
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
● Remember that not even the ESC can 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. The greater safety provided by the ESC should not
encourage you to run any risks.
CAUTION
● To ensure that the ESC works 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.
● Any modifications made to the vehicle (for example, to the engine,
brake system, running gear or to the combination of wheels and tyres) may
affect the operation of the ABS, EDL, ESC and ASR. Anti-lock brake system (ABS)
The anti-lock brake system prevents the wheels locking during braking
⇒ page 169.

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 driven wheels using the ABS
sensors (in case of an EDL fault the warning lamp for ABS lights up)
⇒ page 71.
At speeds of up to approximately 80 km/h (50 mph), it is able to balance
out differences 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 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. 
