Each time the set speed is changed, DSR
will appear in the multifunction dis-
play and the newly set speed is shown.
Off-road driving program
The off-road driving program is designed to
assist the driver when driving off-road in
terrain and crossing water. The off-road
driving program adjusts the engine power
and shifting of the automatic transmission
to be more suitable for the off-road use of
the vehicle. In addition, the ABS, ESP
®,
and 4-ETS designed for off-road use are
automatically activated.
In the following situations you should
switch to the Off-road driving program:


during off-road driving


when crossing water


when towing up or down on steep
gradientsThe switch is located on the lower part of
the center console.

Press ADS switch1 repeatedly until
the desired suspension tuning is
reached.
Vehicle level control*
The vehicle level control automatically
regulates the ride height to

reduce fuel consumption


improve driving stability by lowering
the center of gravity
The vehicle automatically regulates its ride
height based on the set vehicle height and
the current speed:


The ride height of the vehicle is re-
duced with increasing vehicle speed.


The ride height of the vehicle changes
from the high-speed level back to the
normal highway level as the vehicle
speed is decreased.
The parked vehicle begins adjusting to the
set vehicle level as soon the doors and tail-
gate are


unlocked
or


opened.
In order to operate the vehicle level control
switch (
page 252), however, the engine
must be running.
For safety reasons, the vehicle lowers only
when all doors are closed. The lowering
procedure is interrupted as soon as a door
is opened. The lowering will resume as
soon as all doors are closed.
iThe setting is stored when you turn off
the engine.
Warning!
G
Please be aware that by raising the vehicle
level, the center of gravity also rises. There-
fore, always ensure that the vehicle level is
as low as possible. With higher ride height
the ESP
® may activate earlier in certain
situations.
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 ve-
hicle.
For safety reasons, the vehicle can only be
lowered with the doors closed. Lowering is
interrupted if a door is opened and will con-
tinue after the door is closed again.

!
Keep in mind that in rough or uneven
terrain, adjusting the vehicle to a lower
level may cause the vehicle underbody
to come in contact with the ground and
result in damage to the vehicle under-
body. Always make sure the vehicle
has sufficient ground clearance before
adjusting it to a lower level.!Before jacking up the vehicle with
equipment that lifts one or more of the
wheels completely off of the ground,
remove the SmartKey from the starter
switch.!Please also note the information in the
section on towing (
page 472).
iThe activation thresholds are defined
by the set suspension tuning
(page 249).
iThe high-speed level is not available if
towing a trailer. For more information
on towing a trailer, see “Trailer towing”
(page 314).
iFor off-road driving, please observe the
corresponding section in this manual
(page 306).

Setting the vehicle level*
The switch is located on the lower part of
the center console.
1Vehicle level switch
2Indicator lampThe following vehicle chassis ride heights
can be selected using the vehicle level
switch in the center console:
The following is the approximate change in
ride height as compared to the highway
level for each of the level settings:
iThe vehicle is automatically lowered to
the high-speed level when the vehicle
exceeds a certain speed threshold and
is automatically raised to the highway
level when vehicle speed drops below a
certain speed threshold. Note the ex-
ception in the ADS SPORT mode, where
the system disregards the highway lev-
el and automatically lowers the vehicle
to the high-speed level.
In comparison to vehicle behavior
when in the ADS AUTO mode,

the vehicle is lowered to the
high-speed level when set to the
SPORT mode,


and remains at the highway level
over a greater speed range when
set to the COMFORT mode.

(page 249), the vehicle will be low-
ered to the high-speed level when trav-
eling at higher speeds. At speeds below
40 mph (64 km/h) at the latest, it will
be returned to the highway level.
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, es-
pecially at times of snow and ice. See
“Cleaning the Parktronic system sensors”
(page 377).
Interference caused by other ultrasonic sig-
nals (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.


255 Controls in detail
Driving systems
The Parktronic system is an electronic
parking aid and 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,
release the parking brake, and set the
automatic transmission toD,R, orN.
The Parktronic system deactivates at
speeds over approximately 11 mph
(18 km/h). At lower speeds the Parktronic
system turns on again.
The Parktronic system also deactivates
when you set the automatic transmission
toP or depress the parking brake pedal.The Parktronic system monitors the sur-
roundings of your vehicle with six sensors
in the front bumper and four sensors in the
rear bumper.
1Sensors in the front bumper
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 377).
Warning!
G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.
