WARNING■The general information relating to the use of assistance systems must
be observed » page 142, in section Introduction .■
During the parking process, the system automatically performs rapid
steering movements. While it is doing so, do not place your hands between
the steering wheel – risk of injury!
■
During a parking manoeuvre on loose or slippery surfaces (gravel, snow,
ice, etc.) you may stray from the calculated road. It is therefore recommen-
ded that you do not use the system in such situations.
CAUTION
The correct evaluation of the parking space and the parking procedure de-
pends on the circumference of the wheels on the vehicle.■
The system only works correctly if the vehicle is fitted with the wheel size
approved by the manufacturer.
■
Abstain from using the system when the vehicle is fitted with snow chains or
a temporary spare wheel.
■
If wheels other than those approved by the manufacturer are mounted, the
resulting position of the vehicle in the parking space can differ slightly. This
can be avoided by readjusting the system at a specialist garage.
CAUTION
If other vehicles are parked behind the kerb or on it, the system can also guide
your vehicle beyond the kerb or onto it. Ensure that the wheels or the wheel
rims of your vehicle are not damaged and if necessary intervene in time.
Note
■ We recommend performing the parking at a safe speed to about 5 km / h.■The driver can stop the parking process at any time by pressing the symbol
key » Fig. 191
on page 156 or by a driver steering intervention.FunctioningFig. 191

speed or the distance to the vehicle ahead without the accelerator or brake
pedal being pressed.
The front of the vehicle and the distance to the vehicle ahead is monitored by
a radar sensor » page 143.
The state in which the ACC maintains the speed or the proximity is described
as control from here on.
WARNING■
The general information relating to the use of assistance systems must
be observed » page 142, in section Introduction .■
The driver must always be ready to take over steering of the vehicle him-
self (accelerate or brake).

Special driving conditionsFig. 205
Special conditions: Cornering / narrow vehicles or vehicles trav-
elling side by side
Fig. 206
Special conditions: Lane changes of other vehicles / stationary
vehicles
Read and observe
on page 163 first.
The following and similar situations require special attention of the driver.
When cornering
When driving around long bends the ACC may respond to a vehicle in the adja-
cent lane » Fig. 205 -
. Your own vehicle is regulated with respect to this ve-
hicle and will no longer respond to the vehicle ahead.
In such cases, control should be disabled by accelerating, applying the brake or
pressing the button on the operating lever
» Fig. 204 on page 165 .
167Assist systems
Narrow vehicles or vehicles travelling side by side
Narrow vehicles or vehicles travelling side by side are not detected by the ra-
dar sensor until they are within the sensor's range » Fig. 205 -
.
If necessary, slow down the car by applying the brake.
Other vehicles changing lanes
Vehicles that change onto the lane with a small proximity » Fig. 206 -
do not
have to be detected by the radar sensor in time. The result may be a delayed
ACC response.
If necessary, slow down the car by applying the brake.
Stationary vehicles
The ACC does not detect stationary objects! When a vehicle detected by the
ACC turns or sheers off and there is a stationary vehicle in front of this vehicle,
» Fig. 206 -
the ACC does not respond to the stationary vehicle.
In such cases, take over the steering and stop the vehicle by applying the foot
brake.
When overtaking
When your vehicle is being controlled (the speed is lower than that which is
stored) and the indicator is activated, the ACC interprets this situation as
meaning that the driver intends to overtake. The ACC automatically acceler-
ates the vehicle, thereby reducing the proximity to a vehicle ahead.
If the vehicle changes to the fast lane and no vehicle is detected ahead, the
ACC accelerates until the set speed is reached and then keeps it constant.
Acceleration can be cancelled at any time by touch on the brake pedal or
pressing the button on the lever
» Fig. 204 on page 165 .
Vehicles with special load or special body parts
Other vehicles with a load or with body parts protruding from the sides, back
or top of the vehicle contour may not be detected by the ACC.
Control should therefore be disabled whenever you are driving behind or over-
taking such a vehicle.
Towing a trailer
When towing, or in when another accessory is connected to the trailer socket
the ACC control is set with a lower rate. The manner of driving should there-
fore be adapted to this limitation.Information messages
Read and observe
on page 163 first.
The warning symbols are shown in the instrument cluster display.
ACC: no sensor view!
The sensor cover or the sensor is covered or dirty.
Stop the car, switch off the engine and clean the sensor cover or remove the
obstacle » Fig. 174 on page 143 .
If this message appears in winter, the cause can be snow covering the sensor.
The ACC is functional again after the snow melts away from the sensor.
If the message appears again after starting the engine, the position of the lev- er should be
» Fig. 204 on page 165 adjusted.
ACC not available.
The ACC is not available for an unknown reason.
Stop the vehicle, switch off the engine and then start it again. If the ACC is still
not available, push the lever into position . Seek help from a specialist ga-
rage.

With automatic braking the symbol appears » Fig. 208 in the display.
Advance warning
If the system detects a risk of collision, the symbol
» Fig. 208 appears in the
display and you will hear an acoustic signal.
At the same time, the braking system is prepared for possible emergency brak- ing.
The pre-warning display can occur in the following situations.
▶ If there is a risk of collision with a moving obstacle in a driving speed range of
about 30 km/h to about 210 km/h.
▶ There is a risk of a collision with a stationary moving obstacle in a vehicle
speed range of approximately 30 km/h to about 85 km/h.
With a warning the brake pedal must be pressed or the moving obstacle is to
be avoided!
Acute alert
If the driver does not react to the advance warning, the system briefly applies
the brake automatically via an active brake intervention to draw attention to
the potential danger of a collision again.
Automatic Braking
If the driver fails to respond to the acute warning, the system starts to apply
the brakes automatically with increasing stopping power in several stages.
Brake assist
If the driver brakes inadequate with an impending collision, the system auto-
matically increases braking force.
The braking assistance only occurs as long as the brake pedal is being firmly
pressed down.
Note
■ If an automatic brake intervention is triggered by the system, the pressure in
the brake system increases and the brake pedal cannot be operated with the
normal pedal stroke.■
The automatic braking interventions can be cancelled by pressing the accel-
erator pedal or by steering intervention.
