Hill-start assist system
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

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 65) and the Electronic Traction
System (ETS/4-ETS) ( Y page 65).
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 252) or
snow chains as required.

suspension setup adjusts the damping
behavior and the ride height for your vehicle.
The AIRMATIC consists of two components.
The electronically controlled damping system
(Y page 163) and the vehicle level control
(Y page 163).
Damping system
The damping system 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.
XStart the engine.

The firmer suspension tuning in Sport driving
mode provides enhanced road contact.
Select this mode for example, on winding
highways.
XPress damping system switch :.
Indicator lamp ; comes on. The Sport
driving mode with a firmer suspension
tuning is selected. The message

softer. Select this mode when you prefer a
more comfortable driving style on straight
freeways.
XPress damping system switch :.
Indicator lamp = comes on. The Comfort
driving mode is selected. The message
AIRMATIC COMFORT appears in the
multifunction display.
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.
The vehicle chassis ride height is reduced
automatically
Rat a speed exceeding approximately
93 mph (150 km/h)

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
may increase.
The selected vehicle level setting remains
stored in memory even if the SmartKey is
removed from the starter switch.

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. Your vehicle adjusts
its ride height automatically to increase
vehicle safety and to reduce fuel
consumption.

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

GWarning!
The Parking Guidance is only an aid and may
display parking spaces that are not suitable
for parking such as
R no-parking zones
R parking space with unsuitable road/ground
surface
R driveways
R entrances/exits
The Parking Guidance scans for and measures
potential parking spaces when driving past.
Subsequent changes to the parking space are
not taken into account. This may be the case
if the position of the vehicle parked in front or
behind the space changes or obstacles in the
parking space are moved.
The Parking Guidance does not relieve you of
the responsibility to pay attention. If you only
rely on the Parking Guidance, you may cause
an accident and injure yourself and others.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
maneuvering.
GWarning!
The system cannot detect objects located
above the area that the sensors scan. These
objects, e.g. protruding load, overhang, or
truck tail lifts, will be ignored when computing
the parking procedure. The Parking Guidance
might therefore provide untimely steering
instructions. This could cause a collision.
Thus, do not use the Parking Guidance in such
situations.
GWarning!
Make sure no persons or animals are in the
area in which you are maneuvering. You could
otherwise injure them.
! Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts,
elevated crossbars or road curbs). Such
objects may not be detected by the system
and can damage the vehicle.
Use the Parking Guidance for parking spaces
that are
R parallel to the direction of travel
R located on straight streets, i.e. not in
curves
R on the same level as the street, i.e. not on
sidewalks, for example.
Parking instructions:
R On narrow streets, drive by the parking
space as close as possible.
R Parking spaces that are dirty, overgrown or
located in front of trailers may not be
detected correctly.
R Snowfall or heavy rain may cause imprecise
measurement of the parking space.
R Also observe the Parktronic system
warning indicator ( Y page 167) while the
Parking Guidance is active.
R You may not use the Parking Guidance
when transporting cargo that protrudes the
vehicle.
R Do not use the Parking Guidance when
driving with snow chains or when a spare
wheel is mounted.
R How well your vehicle will be parked after
completion of the Parking Guidance
depends on the position and shape of the
vehicles parked in front of and behind the
parking space as well as the conditions of
the immediate surroundings. In certain
cases, the Parking Guidance may guide you
too far into the parking space or not far
enough. If this is the case, cancel the
parking procedure with the Parking
Guidance and correct the vehicle position
yourself.
Detecting a parking space
The Parking Guidance is active when driving
forward. The system operates at a vehicle

automatically for and measures potential
parking spaces on both sides of the vehicle.

In order to be detected by the Parking
Guidance, a parking space must be

Rat least 5 ft (1.5 m) wide
Rat least 4.3 ft (1.3 m) longer than your
vehicle is
A parking space is shown in the multifunction
display when driving by until you have
reached a distance of 50 ft (15 m) from the
space. The Parking Guidance only shows
parking spaces on the passenger side of the
vehicle unless you activate the driver’s side

remain on until the reverse gear is engaged.
