Cornering / narrow vehicles or vehicles travelling side by side
Fig. 298
Lane changes of other vehicles / stationary vehicles
Read and observe
on page 233 first.
The following (and similar) situations require special attention and possibly the intervention of the driver (braking, accelerating etc.).
236Driving
When cornering
When driving into or driving out of long corners, it could be that a vehicle is
travelling in the adjacent lane and is scanned by the radar » Fig. 297 -
. The
host vehicle is then controlled according to this vehicle.
Narrow vehicles or vehicles travelling side by side
A narrow or offset vehicle driving can only be recognized by the ACC if this is
located in the scanning range of the radar » Fig. 297 -
.
Other vehicles changing lanes
Vehicles that change onto the lane with a small distance » Fig. 298 -
may not
be detected by ACC in good time.
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 vehi-
cle, » Fig. 298 -
the ACC does not respond to the stationary vehicle.
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.
Overtaking and towing
Read and observe
on page 233 first.
When overtaking
When your vehicle is being controlled at a speed that is lower than the set
speed and the turn signal is operated, ACC assesses this situation as meaning
that the driver wishes to overtake. The ACC automatically accelerates the vehi-
cle, thereby reducing the proximity to a vehicle ahead.
If your vehicle changes to the overtaking lane and no vehicle is detected
ahead, ACC accelerates until the set speed is reached and then keeps it con-
stant.
Acceleration can be cancelled at any time by touch on the brake pedal or
pressing the button on the lever
» Fig. 296 on page 235 .
Towing a trailer
When towing, or if another accessory is connected to the trailer socket, ACC
control is set with a lower rate. The manner of driving should therefore be
adapted to this limitation.
Malfunctions
Read and observe
on page 233 first.
If, for some unknown reason, ACC is not available, the warning light
appears
in the display of the instrument cluster and an appropriate message is shown.
Sensor covered / dirty
If the sensor cover or the sensor is dirty or covered, a message appears on the
instrument cluster display stating there is no sensor view. Clean the sensor
cover or remove the obstacles » Fig. 264 on page 212 .
If there is no sensor view in the winter, the snow on the sensor under the cov- er could be the reason. The ACC is functional again after the snow melts away
from the sensor.
ACC not available
If the ACC is currently unavailable, a message concerning the unavailability ap-
pears. Stop the vehicle, switch off the engine and then start it again. If ACC
continues to be unavailable, seek the assistance of a specialist garage.
ACC fault
With an ACC fault, an error message appears. Seek help from a specialist ga-
rage.

The system support is provided in the following manner.▶ Alerts you about a dangerous proximity to the vehicle ahead.
▶ Warns you of an impending collision.
▶ Assists with a brake action triggered by the driver.
▶ If the driver fails to respond to a detected danger, an automatic braking ac-
tion is performed.
The system can work only if the following basic conditions are met. The system is activated.
TCS is activated » page 214.
The vehicle is travelling forwards at a speed of more than approx. 5 km/h.
Note
The system can be impaired or may not be available, for example when driving
in “sharp ”curves or with an ESC engagement » page 213.Distance warningFig. 299
Display of the instrument cluster: Proximity warning
Read and observe and on page 238 first.
The display of the distance warning is for vehicles with MAXI DOT display.
If a safe distance from the vehicle ahead is fallen short of, the warning light
appears in the display
» Fig. 299 .
Immediately increase the proximity if the current traffic situation allows you
to do so!
The proximity at which the warning is displayed depends on the current speed.
The warning may occur when driving between about 60 km/h and 210 km/h.

Emergency braking at low speed
If there is a risk of collision in a vehicle speed range of about 5 km/h to 45
km/h, the system triggers an automatic braking.
With automatic braking, the warning light appears in the display
» Fig. 300 .
238Driving
Advance warning
If the system detects a risk of collision, the warning light appears on the dis-
play
» Fig. 300 and an audible signal is emitted.
The pre-warning display can occur in the following situations.
▶ If there is a risk of collision with a moving obstacle at a driving speed range
of approx. 30 km/h to approx. 210 km/h.
▶ If there is a risk of collision with a stationary obstacle at a driving speed
range of approx. 30 km/h to approx. 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 when in danger of a colli-
sion with a moving obstacle, 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 does not respond to acute warning, the system begins to auto-
matically brake the vehicle.
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 acceler-
ator pedal or by means of a steering intervention.
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.Deactivation/activationFig. 301

Operating conditions
246WARNING■ Please take note of the general points relating to the use of assistance
systems » page 212, in section Introduction .■
The system is intended for emergency situations when the driver is sud-
denly unable to take over the steering task. Therefore, never try to test out
the system - there is a risk of an accident!
Function
Read and observe
on page 246 first.
The assistant for emergencies (following known as system) detects inactivity
of the driver, which for example can be caused by a sudden loss of conscious-
ness. The system then performs measures as safely as possible to decelerate
the vehicle to a stop.
The system is only available for vehicles with Automatic transmission.
The assistant for emergencies is an extension of the systems Lane Assist
» page 243 and ACC » page 233 and works by using the functions of these two
systems.
For this reason, the chapters on System Lane Assist and ACC are to be read
carefully and the safety notes are to be observed.
System intervention
If the system detects the driver's inactivity, it draws attention to this fact by a beep and a message on the display of the instrument cluster. It keeps the ve-
hicle in its lane.
If the driver does not take over the steering even after a repeated warning,
the system automatically brakes the vehicle and after it has come to a stand-
still the parking brake switch on.
With automatic braking, the hazard warning system is switched on.
The automatic braking interventions can be cancelled by pressing the acceler-
ator pedal or by means of a steering intervention.
Operating conditions

Towing a trailer
Driving speed
For safety reasons, do not drive with the trailer any faster than 100 km/h
(when the towing vehicle is a passenger car of category M1) or 80 km/h (when
the towing vehicle is a truck of category N1).
Immediately reduce your speed as soon as even the slightest swaying of the
trailer is detected. Never attempt to stop the trailer from “swaying” by acceler-
ating.
Brakes
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply
the brakes gently at first, then brake firmly. This will avoid brake jolts resulting
from the trailer wheels locking.
On downhill sections shift down a gear in good time to also use the engine as
a brake. 254Driving
