162 Controls in detailDriving systems
Driving systemsThe driving systems of your vehicle are de-
scribed on the following pages:

Cruise control, with which the vehicle
can maintain a preset speed.


Rear Park Assist*, with which you can
assist your parking maneuvers.
The BAS, ABS, ESP, 4-ETS and EBB driving
systems are described in the “Safety and
Security” section (
page 71).
Cruise control
Cruise control automatically maintains the
speed you set for your vehicle.
Use of cruise control is recommended for
driving at a constant speed for extended
periods of time. You can set any speed
over 20 mph (30 km/h).
The cruise control function is operated by
means of the cruise control lever.
The cruise control lever is the uppermost
lever found on the left-hand side of the
steering column (
page 22).
iThe cruise control should not be acti-
vated during-off road driving.
Warning!
G
Cruise control is a convenience system de-
signed to assist the driver during vehicle op-
eration. The driver is and must always
remain responsible for the vehicle speed
and for safe brake operation.
Only use cruise control if the road, traffic
and weather conditions make it advisable to
travel at a steady speed.

The use of cruise control can be danger-
ous on winding roads or in heavy traffic
because conditions do not allow safe
driving at a steady speed.


The use of cruise control can be danger-
ous on slippery roads. Rapid changes in
tire traction can result in wheel spin and
loss of control.


Deactivate cruise control when driving
in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.

Briefly push the cruise control lever to

Cruise control will be canceled. The
last speed set will be stored for later
use.iOn uphill or downhill grades, cruise
control may not be able to maintain the
set speed. Once the grade eases, the
set speed will be resumed.
!Moving gear selector lever to
positionN while driving also cancels
cruise control. However, the gear se-
lector lever should not be moved to
positionN while driving except to coast
when the vehicle is in danger of skid-
ding (e.g. on icy roads).iThe last stored speed is canceled when
you turn off the engine.

Warning!
G
The speed stored in memory should only be
set again if prevailing road conditions per-
mit. Possible acceleration or deceleration
differences arising from returning to preset
speed could endanger yourself and others.
iDepressing the accelerator pedal does
not deactivate the cruise control. After
brief acceleration (e.g. for passing), the
cruise control will resume the last
speed set.
iWhen you use the cruise control lever
to decelerate, the transmission will au-
tomatically downshift if the engine’s
braking power does not brake the vehi-
cle sufficiently.

Driving systems
Rear Park Assist*
The Rear Park Assist system is an electron-
ic aid designed to assist the driver during
parking maneuvers. It visually and audibly
indicates the relative distance between the
rear of the vehicle and an obstacle.
The Rear Park Assist system is automati-
cally activated when you switch on the ig-
nition and shift the gear selector lever to
positionR.The Rear Park Assist system monitors the
rear area of your vehicle by means of four
sensors in the rear bumper.
1SensorsWarning!
G
Rear Park Assist (rear Parktronic) is a sup-
plemental system. It is not intended to, nor
does it replace, the need for extreme care.
The responsibility during parking and other
critical maneuvers always rests with the
driver.
Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts, or
street curbs). Such objects may not be de-
tected by the system and can damage the
vehicle.
The operational function of the Rear Park
Assist can be affected by dirty sensors, es-
pecially at times of snow and ice. See
“Cleaning the Rear Park Assist sensors”
(page 234).
Interference caused by other ultrasonic sig-
nals (e.g. working jackhammers or the air
brakes of trucks) can cause the system to
send erratic indications, and should be tak-
en into consideration.Warning!
G
Make sure that no persons or animals are in
the area in which you are maneuvering. You
could otherwise injure them.

166 Controls in detailDriving systemsRange of the sensors
To function properly, the sensors must be
free of dirt, ice, snow and slush. Clean the
sensors regularly, being careful not to
scratch or damage them.Minimum distance
The minimum distance between the sen-
sors and an obstacle is approximately
20 in (50 cm). If you encounter an obstacle
in this range, all the warning lamps light up
and you hear a warning signal. If the obsta-
cle is closer than the minimum distance,
the actual distance may no longer be indi-
cated by the system.
Center
approx. 59.1 in (150 cm)
Corners
approx. 40 in (100 cm)
!During parking maneuvers, pay special
attention to objects located above or
below the height of the sensors (e.g.
planters or trailer hitches). The Rear
Park Assist system will not detect such
objects at close range and damage to
your vehicle or the object may result.
Ultrasonic signals from outside sourc-
es (e.g. truck air brakes or jackham-
mers) may impair the operation of the
Rear Park Assist system.

Warning indicator
Visual signals indicate to the driver the rel-
ative distance between the sensors and an
obstacle. The warning indicator is located
next to the tailgate.Warning indicatorAs your vehicle approaches an object, one
or more segments will light up, depending
on the distance. When the sixth segment
lights, you have reached the minimum dis-
tance.An intermittent acoustic warning will
sound as the fourth segment lights up and
a constant acoustic warning lasting a max-
imum of three seconds will sound for the
sixth segment.
Rear Park Assist malfunction
There is a malfunction in the Rear Park As-
sist system if:


a low warning tone sounds while the
vehicle is reversing
The Rear Park Assist sensors are dirty
or malfunctioning.
Clean the Rear Park Assist system
sensors (
page 234).

Switch on the ignition again.


no segments light up and no warning
sounds
The Rear Park Assist is malfunctioning.
Have the Rear Park Assist system
checked by an authorized
Mercedes-Benz Light Truck Center
as soon as possible.
Malfunction may also be caused by inter-
ference from other radio or ultrasonic sig-
nals.

Check the Rear Park Assist operation
at another location to rule out interfer-
ence from outside radio or ultrasonic
signals.
