AIRMATIC
Introduction
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 343) and the vehicle level control
(Y page 344).
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
Ryour driving style
Rroad surface conditions
Ryour personal settings
The selected setting remains stored in
memory even if the SmartKey is removed
from the starter switch.

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.
The following vehicle levels are available:
Rnormal
Rraised; the vehicle is raised by
approximately 1.0 in (25 mm) compared to
normal level
Rlowered; the vehicle is lowered by
approximately 0.4 in (10 mm) compared to
normal level
You can choose between normal or raised
level when the vehicle is stationary and the
engine is running.
The vehicle chassis ride height is raised or
lowered according to the selected level
setting and to the vehicle speed. With
increasing speed, ride height is reduced by up
to approximately 0.8 in (20 mm). With
decreasing speed, the ride height is again
raised to the selected vehicle level.
iThese height adjustments are so small
that you may not notice any change.
Adjusting vehicle level manually
GWarning!
To help avoid personal injury, keep hands and
feet away from wheel housing area, and stay
away from under the vehicle when lowering
the vehicle chassis.
Select the normal level for driving on normal
roads. Select the raised level for driving on
rough roads or with snow chains. Select the
raised level only when required by current
driving conditions. Otherwise, the handling
may be impaired and the fuel consumption

ABC
The ABC system is an active, computer-
controlled system that adjusts the
suspension hydraulically at all four wheels in
response to various driving situations. It
selects the optimum suspension tuning and
ride height for your vehicle automatically.
Vehicle level control
Your vehicle adjusts its ride height
automatically to increase vehicle safety and
to reduce fuel consumption.
The vehicle chassis ride height is raised or
lowered according to the selected level
setting and to the vehicle speed. With
increasing speed, the ride height is reduced
by up to approximately 0.6 in (15 mm). With
decreasing speed, the ride height is again
raised to the selected vehicle level.
These height adjustments are so small that
you may not notice any change.
GWarning!
When you turn off the engine, the entire
vehicle is lowered. You should therefore make
sure that no one is near the wheel housing or
under the vehicle when you turn off the
engine. Otherwise, parts of the individuals
body could be trapped.
! When you turn off the engine, the entire
vehicle is lowered. When parking, position
your vehicle in such a way that it will not
scrape against a curb, for example, when it
is lowered. Your vehicle could otherwise be
damaged.

All-wheel drive (4MATIC)
In vehicles with all-wheel drive (4MATIC),
both axles are powered at all times when the
vehicle is being operated. The 4MATIC
improves traction in conjunction with the ESC
( Y page 66) and the Electronic Traction
System (ETS/4-ETS) ( Y page 67).
GWarning!
If a drive wheel is spinning due to insufficient
traction:
R While driving off, apply as little throttle as
possible.
R While driving, ease up on the accelerator
pedal.
R Adapt your speed and driving style to the
prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The 4MATIC cannot prevent accidents
resulting from excessive speed.
! Do not tow with one axle raised. Doing so
could damage the transfer case, which is
not covered by the Mercedes-Benz Limited
Warranty. All wheels must be on or off the
ground. Observe instructions for towing the
vehicle with all wheels on the ground.
! Only conduct operational or performance
tests on a two-axle dynamometer. If such
tests are necessary, contact an authorized
Mercedes-Benz Center. You could
otherwise seriously damage the brake
system and/or the transfer case which is
not covered by the Mercedes-Benz Limited
Warranty.
i In winter operation, the maximum
effectiveness of the 4MATIC is only
achieved with winter tires ( Y page 432) or
snow chains as required.
Parktronic system
The Parktronic system with Parking Guidance
is an electronic parking aid with ultrasonic
sensors designed to assist the driver during
parking maneuvers. The Parktronic system
indicates the relative distance between the
vehicle and an obstacle visually and audibly.
The Parktronic system is activated
automatically when
R you switch on the ignition
and
R you release the electronic parking brake
or
R you start the engine
and
R shift the automatic transmission into drive
position D, reverse gear R, or neutral
position N
The Parktronic system deactivates at speeds
above approximately 11 mph (18 km/h). At
lower speeds, the Parktronic system
activates again.
The Parktronic system also deactivates when
you shift the automatic transmission into
park position P or engage the electronic
parking brake and turn off the engine.
The Parktronic system monitors the
surroundings of your vehicle with six sensors

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.
GWarning!
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.
GWarning!
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.
GWarning!
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.
GWarning!
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
ROnly use sets of tires and rims of the same
type and make.
RTires must be of the correct size for the rim.
RBreak in new tires for approximately
60 miles (100 km) at moderate speeds.
RRegularly check the tires and rims for
damage. Dented or bent rims can cause tire

necessary safety information and warning for
the operation of your vehicle.
! To prevent damage during transport, do
not tie down vehicle by its chassis or
suspension parts.
If circumstances do not permit the
recommended towing methods, the vehicle
may be towed with all wheels on the ground
or front axle raised (except vehicles with
4MATIC) only so far as necessary to have the
vehicle moved to a safe location where the
recommended towing methods can be
employed.
! Before towing the vehicle observe the
following instructions:
RDo not tow-start the vehicle. You could
otherwise seriously damage the
automatic transmission which is not
covered by the Mercedes-Benz Limited
Warranty.
RDo not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
RTowing of the vehicle should only be
done using the properly installed towing
eye bolt. Never attach a tow cable, tow
rope or tow rod to the vehicle chassis,
frame or suspension parts.
GWarning!
With the engine not running, there is no power
assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle. Adapt your driving accordingly.
! Avoid pulling the vehicle abruptly or
diagonally, since it could result in damage
to the chassis alignment.
! Do not use the towing eye bolt for
recovery, as this could damage the vehicle.
If in doubt, recover the vehicle with a crane.
