with the curb as the vehicle is lowered. Your
vehicle could otherwise be damaged.
Crosswind driving assistance The crosswind stabilization operates by
changing wheel loads through adjusting the
ABC spring struts. It reduces impairments in
handling when driving in a straight line and
assists during countersteering.
Crosswind driving assistance is active at
vehicle speeds above 50 mph (80 km/h)
when driving straight ahead or cornering
gently.
Active Body Control (ABC) Vehicle level
All vehicles except AMG vehicles:
depending on the vehicle level that has been
set, the vehicle automatically adjusts its
height dependent on the current speed. The
vehicle is lowered by up to 0.6 in (15 mm) as
the speed increases. As the speed is reduced,
the vehicle is raised up to the set vehicle
height.
AMG vehicles: depending on the vehicle
level that has been selected, the vehicle
automatically adjusts its height dependent on
the current speed. The vehicle is lowered by
up to 0.4 in (10 mm) below the normal level
as the speed increases. As the speed is
reduced, the vehicle is raised up to the set
vehicle height.
Select the "Normal" setting for normal road
surfaces and "Raised" for driving with snow
chains or on particularly poor road surfaces.
Your selection remains stored even if you
remove the SmartKey from the ignition lock. Setting the raised vehicle level

Suspension tuning
The electronically controlled ABC suspension
system works continuously. This improves
driving safety and comfort. The system
detects the vehicle level and the vehicle load
and adjusts the setting accordingly. You can 214

active if you select comfort suspension
tuning. The system is operational at speeds
of up to 81 mph (130 km/h).
This function allows bumps in the road
surface to be detected before the vehicle
drives over them. The spring struts are then
actuated, with the result that chassis
movements are significantly reduced when
driving over bumps.
The system is deactivated when you select
the raised vehicle level or the sports
suspension tuning.
The system may be impaired or may not
function if:
R the road surface is insufficiently lit
R there is poor visibility, e.g. snow, rain, fog
or spray
R there is glare, e.g. from the sun or from
oncoming traffic
R the windshield is dirty, fogged up or
covered, for instance by a sticker, in the
vicinity of the camera
R the road surface has no texture or is
reflective, e.g. in the case of newly laid
asphalt, concrete slabs or puddles
R the distance to the vehicle in front is too
short
R sections of the route have a very small
radius of curvature
R you accelerate hard or brake sharply AIRMATIC
General notes AIRMATIC is an air suspension with variable
damping for improved driving comfort. All-
round level control ensures the best possible
suspension and constant ground clearance,
even with a laden vehicle. When you drive
fast, the vehicle is lowered automatically to
improve driving safety and to reduce fuel
consumption. There is also the option to
manually adjust the vehicle level. AIRMATIC consists of level setting, level control and the
Adaptive Damping System ADS.
Important safety notes G
WARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
between the vehicle body and the wheels or
underneath the vehicle. There is a risk of
injury.
Make sure no one is underneath the vehicle
or in the immediate vicinity of the wheel
arches when the vehicle is being lowered.
Vehicle level Setting the raised vehicle level
It is possible to choose between the "Normal"
and "Raised" vehicle levels. Select the
"Normal" setting for normal road surfaces
and "Raised" for driving with snow chains or
on particularly poor road surfaces. Your
selection remains stored even if you remove
the SmartKey from the ignition lock.

Closing the hood X
Lower the hood and let it fall from a height
of approximately 8 in (20 cm).
X Check that the hood has engaged properly.
If the hood can be raised slightly, it is not
properly engaged. Open it again and close
it with a little more force. Engine oil
General notes Depending on your driving style, the vehicle
consumes up to 0.9 US qt (0.8 liters) of oil per
600 miles (1,000 km). The oil consumption
may be higher than this when the vehicle is
new or if you frequently drive at high engine
speeds.
Depending on the engine, the oil dipstick may
be in a different location.
When checking the oil level:
R
park the vehicle on a level surface.
R the engine should be switched off for
approximately five minutes if the engine is
at normal operating temperature.
R if the engine is not at normal operating
temperature, e.g. if the engine was only
started briefly, wait about 30 minutes
before carrying out the measurement.
