Changing the speed
Press the rocker reel 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 reel is pressed to the
point of resistance, the desired speed in‐
creases or decreases by approx.
1 mph/1 km/h.▷Each time the rocker reel is pressed past
the point of resistance, the desired speed
increases or decreases by a maximum of
5 mph/10 km/h.
Hold the rocker reel in position to repeat the
action.

Adjust the distance according to the traf‐
fic and weather conditions; otherwise, there is
the risk of an accident. Maintain the prescribed
safety distance.◀

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

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.◀

Cruise controlThe concept The system maintains a preset speed via the
buttons on the steering wheel. The system
brakes on downhill gradients if engine braking
is insufficient.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.
Hints Unfavorable conditions
Do not use the system if unfavorable
conditions make it impossible to drive at a con‐
stant speed, e.g.:▷On winding roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
Otherwise, you could lose control of the vehi‐
cle and cause an accident.◀

False warnings
PDC may issue a warning under the following conditions even though there is no obstacle
within the detection range:
▷In heavy rain.▷When sensors are very dirty or covered
with ice.▷When sensors are covered in snow.▷On rough road surfaces.▷On uneven surfaces, such as speed
bumps.▷In large buildings with right angles and
smooth walls, e.g., in underground ga‐
rages.▷Through heavy pollution.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.
Malfunction
A Check Control message is displayed.
The range of the sensors is shown as a shaded
area on the Control Display.
PDC has failed. Have the system checked.
To ensure full functionality:
▷Keep the sensors clean and free of ice.▷dimmedDo not put any stickers on sen‐
sors.▷When using high-pressure washers, do not
spray the sensors for long periods and
maintain a distance of at least 12 in/30 cm.
Surround View

sistance systems that help the driver when
parking, maneuvering, and at complex exits
and intersections.

Rearview camera
The concept The rearview camera provides assistance in
parking and maneuvering backwards. The area
behind the vehicle is shown on the Control
Display.
Hints Check the traffic situation as well
Check the traffic situation around the ve‐
hicle with your own eyes. Otherwise, an acci‐
dent could result from road users or objects
that are not lidtured by the camera.◀

at blind driveways and intersections. Road
users concealed by obstacles to the left and
right of the vehicle can only be detected rela‐
tively late from the driver's seat. To improve
