Caution
Each time the vehicle is parked, first of all apply the handbrake and then additionally
engage the 1st gear.Rear parking aid*The parking aid provides a warnin g of obstacles behind the vehicle.The audible parking aid determines the distance from the rear bumper to an
obstacle behind the car with the aid of ultrasound sensors. These ultrasound
sensors are integrated in the rear bumper.
Range of sensors
The clearance warning begins at a distance of about 160 cm from the obstacle (area
 fig. 87 ). The interval between the warning signals becomes shorter as the
clearance is reduced.
A continuous tone sounds from a distance of approx. 30 cm (area ) - danger area.
Do not reverse any further after this signal sounds! If the vehicle is equipped with
a factory-fitted towing device*, the border of the danger area - continuous tone -
extends 5 cm further behind the vehicle. The vehicle can be extended through an
installed detachable towing device.
On vehicles equipped with a factory-fitted radio*, the distance to the obstruction is
shown graphically in the display. On vehicl es with a factory-fitted towing device, the
sensors are deactivated when towing a trailer. The driver is informed about this by
a graphic display (vehicle towing a trailer) in the radio* display. The factory-fitted
radio* can be set so that the play function volume decreases when activating the
parking aid, see Owner's Manual radio*. This improves the audibility of the parking
aid. Activating
The parking aid is activated automatically when
reverse gear is engaged and the
ignition is turned on. This is confirmed by a brief acknowledgement signal.
Deactivating
The parking aid is deactivated by taking the car out of reverse gear.
WARNING
•
The parking aid is not a substitute for the driver paying proper attention and
it is always the driver's responsibility to take care when parking the vehicle or
carrying out similar manoeuvres.
•
You should therefore satisfy yourself, before reversing, that there is no small
obstacle, such as a rock, thin post, traile r drawbar etc., behind your vehicle. Such
obstacles might not be within the range detected by the sensors.
•
Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the signal of the pa rking aid. Thus, such objects or people
may not be recognised by the sensors of the parking aid.Note
•
The parking aid does not operate if you are towing a trailer (applies to models
which feature a factory-fitted towing device*).
•
If a warning signal sounds for about 3 seconds after switching the ignition on
and engaging reverse gear, and there is no obstacle close to your vehicle, this indi-
cates a system fault. Have the fault rectified by a specialist workshop.
•
The sensors must be kept clean and free of ice to enable the parking aid to
operate properly.
Cruise control system (CCS)*IntroductionThe cruise control system (CCS) maintains a constant speed, above approx. 30 km/h
(20 mph), once it has been set, without yo u having to depress the accelerator pedal.
This is only possible to the extent pe rmitted by the power output and braking
power of the engine. The cruise control syst em makes it possible - particularly on
long journeys - for you to rest your “accelerator foot”.

Driving TipsIntelligent TechnologyElectronic stability programme (ESP)*GeneralThe ESP aids you in maintaining control of your vehicle in situations in which the
vehicle is driving at its dynamic limits, such as entering a curve fast. The risk of skid-
ding is reduced and your vehicle thus offers greater driving stability depending on
the conditions of the road surface. The system operates at all speeds.
The following systems are integrated into the electronic stability programme:•
Electronic Differential Lock (EDL),
•
Traction control system (TCS),
•
active driver-steering recommendation (DSR),
•
Antilock brake system (ABS),
•
Brake Assist,
•
Uphill-Start off-Assist.
The ESP system cannot be switched off, only the TCS system can be switched off by
pressing the button fig. 111 , the warning light
 lights up.
Operating principle
The ESP switches on automatically when th e engine is started and then conducts a
self-test. The ESP control unit processes data from the individual systems. It also
processes additional measurement data which are supplied by highly sensitive sensors: the rotational velocity of the ve
hicle about its vertical axis, the lateral
acceleration of the vehicle, the braking pressure and the steering angle.
The direction which the driver wishes to take is determined based on the steering
angle and the speed of the vehicle and is constantly compared with the actual
behaviour of the vehicle. If differences exist, such as the vehicle beginning to skid,
the ESP will automatically brake the appropriate wheel.
The car is stabilised again by the forces which take effect when the wheel is braked.
Intervention into the brake system takes pl ace primarily on the outer front wheel of
a vehicle which tends to oversteer (tendency for the rear of the vehicle to break
away) while occurs this is on the inner re ar wheel of a vehicle which tends to under-
steer (tendency to shift out of the curve). This braking control cycle is accompanied
by noises.
During an intervention of the system, the warning light
 flashes quickly in the
instrument cluster page 25.
The ESP operates in combination with the ABS page 108, “Antilock brake system
(ABS)”. If there is a fault in the ABS system, the ESP also does not operate.
The ESP warning light lights up in the instrument cluster when there is a fault on
the ESP
  page 25.
WARNING
It is also not possible for the ESP to over come the physical limits of the vehicle.
Even if a vehicle fitted with ESP you sh ould still always adapt your style of
driving to the condition of the road surfac e and the traffic situation. This partic-
ularly applies when driving on slippery and wet roads. The increased safety
offered must not tempt you to take greate r risks than otherwise - risk of an acci-
dent!
Note
•
All four wheels must be fitted with the same tyres in order to achieve problem-
free operation of the ESP. Differing rolling circumferences of the tyres can lead to
an undesirable reduction in the engine output.

Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combi-
nation of tyres and wheels) can influence the function of the ESP page 146,
“Accessories, changing and replacing parts”.
Electronic Differential Lock (EDL)*
The electronic differential lock prevents an individual wheel from
slipping.Models fitted with ESP are equipped with electronic differential lock (EDL).
General
The EDL makes it much easier, and sometimes at all possible, to start off, accelerate
and climb a steep hill when the conditions of the road surface are unfavourable.
Operating principle
The EDL is activated automatically, that is without any action on the part of the
driver. It monitors the speeds of the driven wheels with the aid of the ABS sensors.
Should only one drive wheel begin spinning on a slippery surface there will be an
appreciable difference in the speed of the driven wheels. The EDL function brakes
the slipping wheel and the differential transmits a greater driving force to the other
driven wheel. This control process is also accompanied by noises.
Overheating of the brakes
The EDL switches off automatically if unusually severe stresses exist in order to
avoid excessive heat genera tion in the disc brake on the wheel which is being
braked. The vehicle can continue to be driven and has the same characteristics as a
vehicle not fitted with EDL.
The EDL switches on again automatically as soon as the brake has cooled down.
WARNING
•
Carefully depress the accelerator when accelerating on uniformly slippery
road surfaces, such as ice and snow. The driven wheels might still spin despite
the EDL and affect the stability of the vehicle - risk of an accident!
•
You should always adapt your style of dr iving to the condition of road surface
and to the traffic situation even when your vehicle is fitted with EDL. The
increased safety offered must not temp t you to take greater risks than other-
wise - risk of an accident!
Note
•
If the ABS or ESP warning light comes on, this may also indicate a fault in the
EDL. Please have the vehicle inspected as soon as possible by a specialist garage.
•
Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combi-
nation of tyres and wheels) can in fluence the function of the EDL  page 146,
“Accessories, changing and replacing parts”.
Traction control system (TCS)
The traction control system prevents the driven wheels from spin-
ning when accelerating.General
The TCS makes it much easier, and sometimes at all possible, to start off, accelerate
and climb a steep hill when the conditions of the road surface are unfavourable.
Operating principle
The TCS switches on automatically when the engine is started and then conducts a
self-test. The system monitors the speeds of the driven wheels with the aid of the
ABS sensors. If the wheels are spinning, th e force transmitted to the road surface is
automatically adapted by reducing the engi ne speed. The system operates at all
speeds.
The TCS operates in combination with the ABS page 108, “Antilock brake system
(ABS)”. The TCS will not function if a fault exists in the ABS system.
The TCS warning light lights up in the instrument cluster when there is a fault on
the TCS

ment cluster page 25.

take account of the ABS fault in the meantime since you will not know the
extent of the fault and in how far
the braking efficiency is affected.
Note
•
A warning light comes on if a fault occurs in the ABS system
  page 26.

Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combi-
nation of tyres and wheels) can influence the function of the ABS page 146,
“Accessories, changing and replacing parts”.
Brake Assist*During a severe brake application (e.g. if a hazard exists), the Brake Assist increases
the braking force and thus makes it possible to rapidly produce the pressure
required in the brake system.
The majority of drivers do apply the brakes in good time in dangerous situations, but
do not depress the brake pedal with sufficient pressure. Consequently, it is not
possible for the vehicle to achieve its maximum deceleration and the vehicle covers
a greater distance than necessary.
The Brake Assist is activated by the very quick operation of the brake pedal. In such
cases, a much greater braking pressure exists than during a normal brake applica-
tion. This makes it possible, even with a relatively low resistance of the brake pedal,
to produce an adequate pressure in the brake system in the shortest possible time,
which is required for maximum deceleration of the car. You must apply the brake
pedal firmly and hold it in this position in order to achieve the shortest possible
braking distance.
The Brake Assist is able to help you achi eve a shorter braking distance in emergency
situations by rapidly producing the pressure required in the brake system. It fully
exploits the attributes of the ABS. After you release the brake pedal, the function
of the Brake Assist is automatically swit ched off and the brakes operate in the
normal way.
The Brake Assist is part of the ESP system. If a fault occurs in the ESP, the Brake
Assist function is also not availa ble. Further information on the ESP page 105.
WARNING
•
The Brake Assist is also not able to overcome the physical limits of your
vehicle in terms of the braking distance required.
•
Adapt your speed to the conditions of th e road surface and to the traffic situ-
ation.
•
The increased safety offered by the Brake Assist must not tempt you to take
a greater safety risk than otherwise.
Electromechanical power steeringThe power steering enables you to steer the vehicle with less physical force.
With the electromechanical power steering, the steering assist is automatically
adapted to the speed and to the steering angle.
It is still possible to fully steer the vehicle if the power steering fails or if the engine
is not running (vehicle being towed in). The only difference is that greater physical
effort is required.
If there is a fault in the power steering, the warning light
 or  lights up in the
instrument cluster page 24.
WARNING
Contact your specialist garage if the power steering is defective.Tyre inflation pressure-control system*The tyre inflation pressure-control system compares with the aid of the ABS
sensors the speed and also the rolling circumference of the individual wheels. If the
rolling circumference of a wheel is changed, the warning light
