Activating/deactivating: Activate or
deactivate the distance warning function in
the control system (Y page 138).
When activated, the distance warning
function indicator Ä appears in the
multifunction display. Hill-start assist system
G
Warning!
The hill-start assist system is not designed to
function as a parking brake. It does not
prevent the vehicle from moving when parked
on an incline.
Always engage the parking brake in addition
to shifting the automatic transmission into
park position P.
On uphill grades, the hill-start assist system
maintains the pressure in the brake system
for approximately 1 second after you have
released the brake pedal. Therefore, you can
start off smoothly without the vehicle moving
immediately after releasing the brake pedal.
X Depress the brake pedal.
X Shift the automatic transmission into drive
position D or reverse gear R.
X Release the brake pedal.
X Carefully depress the accelerator pedal.
The hill-start assist system is inactive
R when starting off on a level road or downhill
grades
R with the automatic transmission in neutral
position N
R with the parking brake engaged
R if the ESP ®
has switched off due to a
malfunction Rear-axle level control
The rear-axle level control adjusts the vehicle
level for the rear axle. The rear-axle level
control is beneficial because it keeps the vehicle level at the rear axle constant,
independent of the load.
i
Observe the information on towing a
trailer, see “Trailer towing” ( Y page 256). AIRMATIC
The AIRMATIC lets you select the chassis and
suspension setup. The chassis and
suspension setup adjusts the damping
behavior and the ride height for your vehicle.
The AIRMATIC consists of two components.
The Adaptive Damping System (ADS)
(Y page 153) and the vehicle level control
(Y page 154). Adaptive Damping System (ADS)
The Adaptive Damping System (ADS) is
controlled electronically and operates
continuously. It adjusts the damping
characteristics to the current operating and
driving conditions. The damping is adjusted
individually for each wheel. Driving safety and
tire comfort are increased.
The fine tuning of the damping is dependent
on:
R your driving style
R road surface conditions
R your personal settings The following settings are available:

R COMF (for comfort driving)
Indicator lamp = comes on.
X Start the engine.
X Press ADS switch : repeatedly until the
desired suspension tuning is reached.
The setting remains stored when you turn off
the engine. Vehicle level control
Your vehicle automatically adjusts its ride
height.
The all-around vehicle level control provides
best possible suspension and constant
ground clearance. The vehicle lowers at high
speed automatically in order to increase
driving safety and to reduce fuel
consumption.
Changes to the vehicle level should be made
while the vehicle is moving. The vehicle will
then reach the set level as fast as possible.
When you park the vehicle and the ambient
temperature changes, the vehicle level may
change visibly. When the temperature drops,
the vehicle lowers. When the temperature
rises, the vehicle raises.
The vehicle begins adjusting to the set vehicle
level as soon as the doors or tailgate are
unlocked or opened or closed with the vehicle
unlocked.
For major changes in vehicle level, the engine
must be running. G
Warning!
Make sure 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.
! Keep in mind that on 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 underbody. 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.
i The activation threshold is defined by the
ADS setting (Y page 153). Basic settings
The following vehicle chassis ride heights can
be selected using vehicle level control
switch : in the center console:
Level Driving situation
Raised level For driving on rough roads.

Brake fluid level
! If you find that the brake fluid in the brake
fluid reservoir has fallen to the minimum
mark or below, have the brake system
checked for brake pad thickness and leaks
immediately. Contact an authorized
Mercedes-Benz Center immediately. Do
not add brake fluid as this will not solve the
problem. For more information, see
“Practical hints”.
When checking the brake fluid level, the
vehicle must be parked on level ground. The brake fluid level is correct when it is
between lower mark (MIN)
; and upper
mark (MAX) : of the brake fluid reservoir. Tires and wheels
Safety notes
Contact an authorized Mercedes-Benz Center
for information on tested and recommended
rims and tires for summer and winter
operation. They can also offer advice
concerning tire service and purchase. G
Warning!
Replace rims or tires with the same
designation, manufacturer and type as shown
on the original part. For further information
contact an authorized Mercedes-Benz Center.
If incorrectly sized rims and tires are
mounted, the wheel brakes or suspension
components can be damaged. Also, the operating clearance of the wheels and the
tires may no longer be correct.
G
Warning!
Worn, old tires can cause accidents. If the tire
tread is worn to minimum tread depth, or if
the tires have sustained damage, replace
them.
When replacing rims, only use genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can result
in the bolts loosening and possibly an
accident.
Retreaded tires are not tested or
recommended by Mercedes-Benz, since
previous damage cannot always be
recognized on retreads. The operating safety
of the vehicle cannot be assured when such
tires are used. G
Warning!
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possible
damage to your vehicle has occurred, you
should turn on the hazard warning flashers,
carefully slow down, and drive with caution to
an area which is a safe distance from the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have the vehicle towed to the
nearest authorized Mercedes-Benz Center or
tire dealer for repairs. G
Warning!
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle. You
could lose control of the vehicle. Continued
driving with a flat tire or driving at high speed
with a flat tire will cause excessive heat build-
up and possibly a fire. Important guidelines
R Only use sets of tires and rims of the same
type and make.
R Tires must be of the correct size for the rim. Tires and wheels
