Start the engine (
page 34).

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.

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.

256 Controls in detailDriving systemsFront sensors
Rear sensorsMinimum 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 long-
er be indicated by the system.
Warning indicators
Visual signals indicate to the driver the rel-
ative 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
passenger compartment in the roof dome.

3Readiness indicators
Each warning indicator is divided into five
yellow and two red segments for either
side of the vehicle. The Parktronic system
is operational when the readiness
indicators3 are illuminated.
The position of the automatic transmission
determines which warning indicator will be
activated.

!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 sourc-
es (e.g. working jackhammers, car
wash or the air brakes of trucks) may
impair the operation of the Parktronic
system.

ment, only use containers that fit into the
cup holder. Use lids on open containers and
do not fill containers to a height where the
contents, especially hot liquids, could spill
during braking, vehicle maneuvers, or an ac-
cident. Liquids spilled on vehicle occupants
may cause serious personal injury. Liquids
spilled on vehicle equipment may cause
damage not covered by the Mercedes-Benz
Limited Warranty.
When not in use, keep rear the cup holder
closed. An open cup holder may cause injury
to you or others when contacted during
braking, vehicle maneuvers, or in an acci-
dent.
Keep in mind that objects placed in the cup
holder may come loose during braking,

310 OperationDriving instructionsDriving downhill

Select gear range1 on the automatic
transmission (
page 187).


Drive downhill observing the same
rules as driving uphill (
page 308).


On steep inclines, use the Downhill
Speed Regulation (
page 243).


Drive slowly.


Do not drive at an angle to the incline.
Steer into the line of gravity and drive
with the front wheels pointing straight
downhill. Otherwise, the vehicle may
slide sideways off the path and roll
over.


Utilize the engine’s braking power to
reduce vehicle speed.
If this is insufficient, apply the brake
gently. Make sure the vehicle is moving
in the line of gravity.


Check the brakes after a lengthy down-
grade drive.Driving through water
1Fording depth


Before driving through water, deter-
mine its depth.
It should not be deeper than approxi-
mately 20 inches (50 cm).
Make sure you check the water bed.
The ground surface may not be firm
which may result in deeper waters than
expected when driving the vehicle
through it.


For vehicles with level control*, raise
the ride height (
page 250) if neces-
sary.


Switch to the Off-road driving program
(page 248) before driving through
water.


Select gear range1 or2 on the
automatic transmission (
page 187).


Avoid high engine speeds.


Drive through the water slowly and at a
constant speed.

312 OperationDriving instructionsWhen driving over tree stumps, big rocks
and other obstacles, observe the following
rules:

Make sure the Off-road driving program
(page 248) is switched on.


Avoid high engine speeds.


Select gear range1 on the automatic
transmission (
page 187).


Check the vehicle clearance before
crossing obstacles.


Cross obstacles (e.g. tree stumps or
big rocks) very slowly by aiming one of
the front wheels at the center of the ob-
stacle, and repeat same with the rear
wheel.Driving on sand


For vehicles with level control*, raise
the ride height (
page 250) if neces-
sary.


Avoid high engine speeds.


Select the gear range on the automatic
transmission that is appropriate for the
terrain.


In sandy soil, drive at a steady speed as
allowed by conditions. This helps over-
come the vehicle rolling resistance and
reduce the likelihood of the vehicle
sinking into the ground.


Drive in tracks of other vehicles if they
are not too deep and if you have suffi-
cient clearance.
Ruts
A number of off-road tracks or other by-
ways have deep ruts which can cause the
underbody to come in contact with the
ground.


Switch on the Off-road driving program
(page 248).


For vehicles with level control*, raise
the ride height (
page 250) if neces-
sary.


Avoid high engine speeds.


Select gear range1 on the automatic
transmission (
page 187).


Drive next to the ruts rather than
through them if at all possible.


If the ruts are too deep to drive in, drive
with one side of the vehicle on the
grassy center strip if the route permits.
!Special attention is needed when you
cross obstacles on a steep incline.
The vehicle could slide sideways as a
result of its possible slanted position
which in turn may result in the vehicle
tipping or rolling over.
!Check that the ruts are not too deep
and your vehicle’s clearance is suffi-
cient. Otherwise:

your vehicle may be damaged.


the underbody of the vehicle may
come in contact with the ground
and you may get stuck.

327 Operation
Engine compartment
Closing
Let the hood drop from a height of
approximately 1ft (30cm).
The hood will lock audibly.

Check to make sure the hood is fully
closed.
If you can raise the hood at a point
above the headlamps, then it is not
properly closed. Open it again and let it
drop with somewhat greater force.
Engine oil
The amount of oil your engine needs will
depend on a number of factors, including
driving style. Higher oil consumption can
occur when

the vehicle is new


the vehicle is driven frequently at
higher engine speeds
Engine oil consumption checks should only
be made after the vehicle break-in period.
Warning!
G
If you see flames or smoke coming from the
engine compartment, or if the coolant tem-
perature gauge indicates that the engine is
overheated, do not open the hood. Move
away from vehicle and do not open the hood
until the engine has cooled. If necessary,
call the fire department.Warning!
G
The engine is equipped with a transistorized
ignition system. Because of the high voltage
it is dangerous to touch any components (ig-
nition coils, spark plug sockets, diagnostic
socket) of the ignition system

with the engine running


while starting the engine


if ignition is “on” and the engine is
turned manually
Warning!
G
Be careful that you do not close the hood on
anyone.
