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 reversing the ve-
hicle or carrying out similar manoeuvres.
● You should therefore satisfy yourself, before reversing, that there is no
small obstacle, such as a rock, thin post, trailer drawbar etc., in front or behind
your vehicle. Such an obstacle 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 parking aid. Thus, these objects or
people who wear such clothing are not recognised by the sensors of the park-
ing aid. Note
● Only the front parking aid operates if you are towing a trailer (applies only to
models which feature a factory-fitted towing device).
● If a warning signal sounds for about 3 seconds after activating the system and
there is no obstacle close to your car, this indicates a system fault. The fault is
confirmed additionally when the symbol flashes in the button ⇒ fig. 103 - left.
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.
● If the parking aid is activated and the selector lever of the automatic gearbox
is in the position P , warning signal indicates interruption (vehicle can no longer
move).
Cruise control system (CCS) Introduction The cruise control system (CCS) maintains a constant speed, more than 30 km/h
(20 mph), once it has been set, without you having to depress the accelerator
pedal. This is only possible within the range which is permitted by the power out-
put and braking power of the engine. The cruise control system makes it possible
- particularly on long journeys - for you to rest your
“accelerator foot”. WARNING
● For safety reasons, the cruise control system must not be used in dense
traffic or on unfavourable road surfaces (such as icy roads, slippery roads,
loose gravel) - risk of accident!
● In order to prevent unintentional use of the cruise control system, always
switch off the system after use. Note
● Models fitted with a manual gearbox: Always depress the clutch pedal if you
switch on the cruise control system when the gearbox is in Neutral! Otherwise the
engine can rev up unintentionally.
● The cruise control system is not able to maintain a constant speed when driv-
ing on steep downhill sections. The weight of the vehicle increases the speed at
which it travels. One should shift down in good time to a lower gear or slow the
vehicle down by applying the foot brake.
● It is not possible on vehicles fitted with an automatic gearbox to switch on the
cruise control system if the selector lever is in the position P, N or R.
Storing a speed Fig. 104 Operating lever: Rocker button
and switch of the cruise control system
The cruise control system is operated by means of the switch A
⇒ fig. 104 and
the rocker button B in the left lever of the multi-functional switch.
– Press the switch A into the position ON.
– After the desired speed has been reached, press the rocker button B into the
SET position. £104
Starting-off and Driving
Driving Tips
Intelligent Technology General information WARNING
Lack of fuel can cause irregular engine running or lead to shut down the en-
gine. Consequently, the systems described in this chapter may to lose their ef-
fectiveness, resulting in loss of vehicle control – risk of accident!
Electronic stability programme (ESP)
General Fig. 138 ESP system: Switch for TCS
The 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
skidding is reduced and your car 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 Assist.
The ESP system cannot be switched off with the ⇒
fig. 138 button; only the TCS
system is switched off, the warning light instrument cluster lights up.
Operating principle
The ESP switches on automatically when the engine is started and then conducts
a self-test. The ESP control unit processes data from the individual systems. It al-
so processes additional measurement data which are supplied by highly sensitive
sensors: the rotational velocity of the vehicle about its vertical axis, the lateral ac-
celeration 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 be-
haviour of the vehicle. If differences exist, such as the car 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 place 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 rear wheel of a vehicle which
tends to understeer (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 in the instru-
ment cluster ⇒ page 26.
The ESP operates in combination with the ABS ⇒ page 158, 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 26. £154
