pear in the multifunction display.
Warning!
G
If the accelerator pedal is depressed while
the Downhill Speed Regulation is activated,
the vehicle can drive faster than the pro-
grammed set speed. You should therefore
drive downhill with particular caution as it
could otherwise lead to an accident and/or
serious injury to you or others. Keep in mind
that as soon as you remove the foot from
the accelerator pedal with the DSR switched
on, the DSR will start regulating the vehicle’s
speed including use of brakes where re-
quired. Depending on the programmed set
speed, actual vehicle speed and gradient,
the DSR can cause the vehicle to slow down
rapidly. Sudden and unexpected decelara-
tion can result in loss of vehicle control,
causing an accident and/or serious person-
al injury to you and others.
iThe DSR can only be switched on if the
vehicle speed is below 18 mph
(Canada: 30 km/h).

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.
