Lane changing
Distronic has not yet detected the vehicle
changing lanes. There will be insufficient
distance to the lane-changing vehicle.Narrow vehicles
Because of their narrow profile, the vehi-
cles traveling near the outer edges of the
lane have not yet been detected by
Distronic. There will be insufficient
distance to the vehicles ahead.Distance warning function*
When Distronic* is deactivated, this
function will continue to warn you when
recognizing a stationary obstacle or a
slower vehicle moving in your vehicle’s
path and the danger of a collision exists:

The distance warning lampl in the
instrument cluster comes on.

An intermittent warning will sound if
necessary.
If these warnings are issued, you must
brake manually to maintain a safe distance
and avoid a collision with the preceding
vehicle.
When pressing the brake pedal, the warn-
ing sound ceases. The warning sound will
also cease when the distance to the
preceding vehicle is sufficient again with-
out applying the brakes. In this case, the
distance warning lamp will also go out.

function
When the distance warning function is
switched on, you will see the : symbol
in the Standard display. When the distance
warning function is deactivated the
:symbol will not appear.
AIRMATIC*
The AIRMATIC* consists of two compo-
nents:

Adaptive Damping System (ADS)*
(
page 286): Automatically optimizes
your vehicle’s suspension tuning.

Vehicle level control* (page 286):
Regulates the ride height of the vehicle.
Warning!G
If the distance warning lampl in the in-
strument cluster comes on while driving
and/or an intermittent warning sounds,
immediate attention on the part of the driver
is required. As required by the traffic
situation, apply the brakes and navigate
around a possible obstacle. However, do not
drive by relying on the distance warning
function, as this will result in an emergency
braking application. This will not always
enable you to avoid a collision, especially
when traveling on varying road surface
conditions and with varying driver reaction.
Complex driving situations are not always
fully recognized by the distance warning
function. This could result in wrong or miss-
ing distance warnings.
Warning!G
R 63 AMG only: When you turn off the
engine, the vehicle may be lowered
(
page 288). To avoid personal injury,
make sure that nobody is in the vicinity of
the wheel housing or under the vehicle when
you turn off the engine.
!R 63 AMG only: When you turn off the en-
gine, the vehicle may be lowered (
page 288).
When parking, make sure there is sufficient
clearance under the vehicle for it to lower with-
out making contact with the road curb for exam-
ple. Otherwise, the vehicle could be damaged.

Driving systems
Basic settings (except R 63 AMG)
There are two settings from which to
choose:

Raised level, for driving on rough roads

Highway level, for driving on paved
roads in fair or better conditionThe vehicle’s ride height changes by the
approximate values given in table below
according to the set level:
The vehicle lowers to highspeed level
automatically when

the vehicles speed exceeds
70 mph (112 km/h)

the vehicles speed is between
60 mph (96 km/h) and
70 mph (112 km/h) for longer
than 20 seconds
Warning!G
Make sure that no one is near the wheel
housing or under the vehicle when you lower
the vehicle while it is standing still. Limbs
could become wedged into or under the
vehicle.
For safety reasons, the vehicle can only be
lowered with all doors and the tailgate
closed. Lowering is interrupted if a door or
the tailgate is opened and will continue after
the door is closed again.
Warning!G
Adapt your speed and driving to possible
changed driving behavior of the vehicle after
changing the vehicle level. The ESP
® cannot
prevent accidents, including those resulting
from excessive speed. The ESP
® cannot
prevent the natural laws of physics from
acting on the vehicle.
!Keep in mind that in rough or uneven roads,
adjusting the vehicle to a lower level may cause
the vehicle underbody to come in contact with
the road and result in damage to the vehicle un-
derbody. Always make sure the vehicle has suffi-
cient ground clearance before adjusting it to a
lower level.
!Before jacking up the vehicle with equip-
ment that lifts one or more of the wheels com-
pletely off the ground, remove the SmartKey
from the starter switch.
!Please also note the information in the
section on towing (
page 517).
iThe activation threshold is defined by the set
suspension tuning (
page 286).
iThe third available level is the highspeed
level that is set automatically.

Parktronic* (Parking assist)
The Parktronic system is an electronic aid
designed to assist the driver during
parking maneuvers. It visually and audibly
indicates the relative distance between the
vehicle and an obstacle.
The Parktronic system is automatically
activated when you

switch on the ignition or start the
engine
and

release the parking brake
and

set the automatic transmission to
positionD,R, orNThe Parktronic system deactivates at
vehicle speeds exceeding approximately
11 mph (18 km/h). At lower vehicle
speeds, the Parktronic system turns on
again.
The Parktronic system also deactivates
when you set the automatic transmission
to positionP or depress the parking brake
pedal.
The Parktronic system monitors the
surroundings of your vehicle with six sen-
sors in the front bumper and four sensors
in the rear bumper.
1Sensors in the front bumper
Warning!G
Parktronic is a supplemental 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 road
curbs). Such objects may not be detected by
the system and can damage the vehicle.
The operational function of the Parktronic
system can be affected by dirty sensors,
especially at times of snow and ice. See
“Cleaning the Parktronic system sensors”
(
page 414).
Interference caused by other ultrasonic
signals (e.g. working jackhammers, car
wash, or the air brakes of trucks) can cause
the system to send erratic indications, and
should be taken into consideration.
Warning!G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.

Range 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 damaging the sensors, see
“Cleaning the Parktronic* system sensors”
(
page 414).Front sensors
Rear sensors
Minimum distance
If the system detects an obstacle in this
range, all the distance warning segments
illuminate and you hear a warning signal. If
the obstacle is closer than the minimum
distance, the actual distance may no
longer be indicated by the system.
!During parking maneuvers, pay special
attention to objects located above or below the
height of the sensors (e.g. planters or trailer
hitches).
The Parktronic system will not detect such
objects at close range and damage to your
vehicle or the object may result.
Ultrasonic signals from outside sources (e.g.
working jackhammers, car wash or the air brakes
of trucks) may impair the operation of the
Parktronic system.

Warning indicators
Visual signals indicate to the driver the
relative distance between the sensors and
an obstacle. The warning indicator for the
front area is located above the center air
vents in the dashboard. The warning indi-
cator for the rear area is located in the rear
overhead control panel.
Front area warning indicator
1Left side of the vehicle
2Right side of the vehicle
3Readiness indicatorsEach warning indicator is divided into five
yellow and two red distance segments for
either side of the vehicle. The Parktronic
system is ready when the yellow readiness
indicators3 are illuminated.
The current transmission position deter-
mines which warning indicator will be
activated.As your vehicle approaches an object, one
or more distance segments will illuminate,
depending on the distance. When the
seventh distance segment illuminates, you
have reached the minimum distance.

Front area: An intermittent acoustic
warning lasting a maximum of
2 seconds will sound as the first red
distance segment illuminates and a
constant acoustic warning lasting a
maximum of 2 seconds will sound for
the second red distance segment. The
signal is canceled when the automatic
transmission is set to positionP or the
parking brake is set.

Rear area: An intermittent acoustic
warning lasting a maximum of
2 seconds will sound as the first red
distance segment illuminates and a
constant acoustic warning lasting a
maximum of 2 seconds will sound for
the second red distance segment. The
signal is canceled when the automatic
transmission is set to positionD, P, or
the parking brake is set.

there is a malfunction in the Parktronic
system. The Parktronic system will auto-
matically switch off after 20 seconds and
the indicator lamp in the Parktronic switch
comes on.
Have the Parktronic system checked
by an authorized Mercedes-Benz Light
Truck Center as soon as possible.If only the red distance segments illumi-
nate and no acoustic warning sounds, the
Parktronic system sensors are dirty (e.g.
slush, snow or ice) or there is an interfer-
ence from other radio or ultrasonic signals
(e.g. working jackhammers, car wash or
the air brakes of trucks). The Parktronic
system will automatically switch off after
20 seconds and the indicator lamp in the
Parktronic switch comes on.
