Hints Enclosed areas
Do not let the engine run in enclosed
areas; otherwise, breathing of exhaust fumes may lead to loss of consciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless but highly toxic
gas.◀
Unattended vehicle
Do not leave the vehicle unattended with
the engine running; doing so poses a risk of
danger.
Before leaving the vehicle with the engine run‐
ning, set the parking brake and place the trans‐
mission in position P or neutral to prevent the
vehicle from moving.◀
Repeated starting in quick succession
Avoid repeated unsuccessful attempts to
start the vehicle or starting the vehicle several
times in quick succession. Otherwise, the fuel
is not burned or is inadequately burned, posing
a risk of overheating and damage to the cata‐
lytic converter.◀
Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving at
moderate engine speeds.

Warning stages
Prewarning
This warning is issued, for example, when
there is the impending danger of a collision or
the distance to the vehicle ahead is too small.
Acute warning with braking function
Warning of the imminent danger of a collision
when the vehicle approaches another object at
a relatively high differential speed.
The acute warning prompts the driver to inter‐
vene and, if there is the danger of a collision, is
accompanied by a braking intervention.
The braking intervention may be executed with
maximum braking force and for a brief period
only as necessary.
The intervention can bring the vehicle to a
complete stop.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on
and Dynamic Traction Control DTC is acti‐
vated.Seite 101SafetyControls101

The LED goes out.Warning with braking function Adapting your speed and driving style
The warning does not relieve the driver
of the responsibility to adapt his or her driving
speed and style to the traffic conditions.◀
Display
If a collision with a vehicle detected in this way
is imminent, a warning symbol appears on the
instrument cluster and in the Head-up Display.SymbolMeasureThe vehicle lights up red: prewarn‐
ing.
Increase braking and distance.The vehicle flashes red and an
acoustic signal sounds: acute warn‐
ing.
You are requested to intervene by
braking or making an evasive ma‐
neuver.
Braking intervention
The warning prompts the driver himself to in‐
tervene. During the warning, the maximum
braking force is used, even with light pressure
on the brake pedal. In addition, if there is a risk
of collision, the system can assist with a slight
braking intervention. The intervention can
bring a vehicle traveling at slow speed to a
complete stop.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on
and Dynamic Traction Control DTC is acti‐
vated.
The braking intervention can be interrupted by
pressing on the accelerator or by actively mov‐
ing the steering wheel.
When towing or tow-starting the vehicle,
switch off the collision warning with braking
function to prevent undesired interventions.
System limits Be alert
Due to system limitations, warnings may
be not be issued at all, or may be issued late or
improperly. Therefore, always be alert and
ready to intervene; otherwise, there is the dan‐
ger of an accident occurring.◀
Detection range
The system's detection capabilities are limited.
This may result in the warning not being is‐
sued or being issued late.
For example, the following situations may not
be detected:▷Slow moving vehicles when you approach
them at high speed.▷Vehicles that suddenly swerve in front of
you or sharply decelerating vehicles.▷Vehicles with an unusual rear appearance.▷Two-wheeled vehicles ahead of you.▷Pedestrians.
Functional limitations
The system may not be fully functional in the
following situations:
▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the driving stability control systems are
limited or deactivated, for example, DSC
OFF.▷If the camera in the mirror or the radar sen‐
sor is dirty or obscured.▷During calibration of the camera immedi‐
ately after vehicle shipment.Seite 104ControlsSafety104
