Cruise control can be used.
Switch off Deactivated or interrupted system
With deactivated or interrupted system
use your brakes, steering and moves as usual
to avoid the chance of an accident.◀
To switch off the system while standing, step
on brake pedal at the same time.
Press button on the steering wheel.▷If active: press twice.▷If interrupted: press once.
The displays go out. The stored desired speed
is deleted.
Interrupting Press button on the steering wheel.
If interrupting the system while stationary,
press on the brake pedal at the same time.

following situations:
▷When the brakes are applied.▷When selector lever position D is disen‐
gaged.▷When DTC Dynamic Traction Control is
activated or DSC is deactivated.▷When DSC is actively controlling stability.▷When SPORT+ is activated with Driving
Dynamics Control.▷If the safety belt and the driver's door are
opened while the vehicle is standing still.▷If the system has not detected objects for
an extended period, e.g., on a road with
very little traffic without curb or shoulder
markings.▷If the detection range of the radar is dis‐
rupted, e.g., by dirt or heavy fog.
Maintaining, storing, and changing the
speed
Hints Adjusting the desired speedModify desired speed to road conditions
and be ready to brake at all times; otherwise,
there is the risk of an accident.◀
Differences in speed
Large differences in speed relative to
other vehicles cannot be compensated by the
system such as in the following situations:
▷When fast approaching a slowly moving
vehicle.▷When another vehicle suddenly swerves
into the wrong lane.▷When stationary objects are approached at
high speed.◀
Maintaining/storing the speed
Press button.
Or:

Changing the speed
Press the rocker switch up or down repeatedly
until the desired speed is set.
If active, the displayed speed is stored and the vehicle reaches the stored speed when the
road is clear.▷Each time the rocker switch is pressed to
the point of resistance, the desired speed
increases or decreases by approx.
1 mph/1 km/h.▷Each time the rocker switch is pressed
past the point of resistance, the desired
speed increases or decreases by a maxi‐
mum of 5 mph/10 km/h.
Hold the rocker switch in position to repeat the
action.

tance, refer to page 146.
Calling up the desired speed and
distance
While driving Press button with the system
switched on.
In the following cases, the stored speed value
is deleted and cannot be called up again:▷When the system is switched off.▷When the ignition is switched off.
While standing
The system brought the vehicle to a complete
standstill:
▷Green marking in the speedometer:
Your vehicle accelerates automatically as
soon as the vehicle in the range of the ra‐
dar sensor moves off.▷Speedometer markings turn orange: no au‐
tomatic driving off.
To accelerate to the desired speed auto‐
matically, press the accelerator or press
the RES or SET button.
Rolling bars in the distance display indicate
that the the vehicle detected by the radar sen‐
sor has driven off.
Your vehicle was brought down to a halt
through stepping on the brake pedal and it is
standing behind another vehicle:
1. Press button to call up a stored
desired speed.2.Release the brake pedal.3.Step on the accelerator briefly, or press the

The indicator and warning lights do not
relieve the driver of the responsibility to adapt
his or her desired driving speed and style to
the traffic conditions.◀

Displays in the Head-up DisplaySome system information can also be dis‐
played in the Head-up Display.
Distance information The symbol is displayed when the dis‐
tance from the vehicle traveling ahead
is too short.▷Active Cruise Control switched off.▷Display in the Head-up Display selected,

System limits
Speed range The system is best used on well-constructedroads.
The minimum speed that can be set is
20 mph/30 km/h. The maximum speed that
can be set depends on the vehicle.
The system can also be activated when sta‐
tionary.
Comply with the legal speed limit in every sit‐
uation when using the system.
Detection range
The detection lidacity of the system and the
automatic braking lidacity are limited.
Two-wheeled vehicles for instance might not
be detected.
Limited detection potential
Because of the limited possible detec‐
tion, you should be alert at all times so that you
can intervene if needed; otherwise, there is the
risk of an accident.◀
Deceleration
The system does not decelerate for:▷Pedestrians or similar slow-moving road
users.▷Red traffic lights.▷Cross traffic.▷Oncoming traffic.
Swerving vehicles
A vehicle driving in front of you is not detected
until it is completely within the same lane as
your vehicle.
Swerving vehicles
If a vehicle driving ahead of you suddenly
swerves into your lane, the system may not be
able to automatically restore the selected dis‐
tance. This also applies to major speed differ‐
ences to vehicles driving ahead of you, e.g.,
when rapidly approaching a truck. When a ve‐
hicle driving ahead of you is reliably detected,
the system requests that the driver intervene
by braking and carrying out evasive maneu‐
vers, if needed. You must react yourself; other‐
wise, there is the risk of an accident.◀

Cornering
If the desired speed is too high for a curve, the
speed is reduced slightly, although curves can‐
not be anticipated in advance. Therefore, drive
into a curve at an appropriate speed.
In tight curves the system offers only restricted
detection where a vehicle ahead of you might
be detected late or not at all.
When you approach a curve the system may
briefly report vehicles in the next lane due to
the bend of the curve. If the system deceler‐
ates you may compensate it by briefly acceler‐
ating.
After releasing the gas pedal the system is re‐
activated and controls speed independently.
Driving away In some situations, the vehicle cannot drive off
automatically; for example:
▷On steep inclines.▷From behind bumps in the road.
In these cases, step on the accelerator pedal.
Radar sensor

The transmitter and receiver units comply with
part 15 of the FCC/Federal Communication
Commission regulations. Operation is gov‐
erned by the following:

Malfunction
The system cannot be activated if the radar sensor is not aligned correctly. This may be
caused by damage incurred during parking,
e.g.
A Check Control message is displayed if the
system fails.
The function for detecting and responding
when approaching stationary vehicles may be limited in the following situations:
▷During calibration of the camera immedi‐
ately after vehicle shipment.▷If the camera is malfunctioning or dirty. A
Check Control message is displayed.Seite 148ControlsDriving comfort148
