The steering interventions are carried out with a
limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with
a visual warning. A steering wheel symbol
appears in the multifunction display. If you have
still not started to steer and have not taken hold
of the steering wheel after five seconds at the

fort
Rthe vehicle load

ROAD SURFACE SCAN
iThis function is not available in all countries.
The ROAD SURFACE SCAN function monitors
the road in front of the vehicle using multifunc-
tion camera :at the top of the windshield. This
function is automatically 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 signifi-
cantly reduced when driving over bumps.
The system is deactivated when you select the
raised vehicle level or sports mode.
The system may be impaired or may not function
if:
Rthe road surface is insufficiently lit
Rthere is poor visibility, e.g. snow, rain, fog or
spray
Rthere is glare, e.g. from the sun or from
oncoming traffic
Rthe windshield is dirty, fogged up or covered,

AIRMATIC
General notes
AIRMATIC is an air suspension with variable
damping for improved driving comfort. All-round
level control ensures the best possible suspen-
sion 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 PLUS.
Important safety notes
GWARNING
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.
XStart the engine.
If indicator lamp ;is not lit:
XPress button :.
Indicator lamp ;lights up. The vehicle is
raised by 1.0 in (25 mm) compared to the
normal level.

multifunction display.
iThe message disappears after ten seconds,
irrespective of the level reached. If necessary,
the vehicle is raised further.
The "Raised level" setting is canceled if you:
Rdrive at a speed above approximately 75 mph
(120 km/h)
Rdrive for approximately three minutes at a
speed above 50 mph (80 km/h)

Suspension tuning
General notes
The Adaptive Damping System ADS PLUS auto-
matically controls the calibration of the damp-
ers.
The damping is tuned individually to each wheel
and depends on:
Ryour driving style, e.g. sporty
Rthe road surface condition, e.g. bumps
Ryour individual selection, i.e. sports or com-
fort
Your selection remains stored even if you
remove the SmartKey from the ignition lock.
iYou can choose between the sporty and
comfortable mode. One of the two modes is
always active.

with the road. Select this mode when employinga sporty driving style, e.g. on winding country
roads.

sage appears in the multifunction display.
Comfort tuning
In comfort mode, the driving characteristics of
your vehicle are more comfortable. Therefore,
select this mode if you favor a more comfortable
driving style. Select comfort mode also when
driving fast on straight roads, e.g. on straight
stretches of highway.
XIf indicator lamp ;is not lit:press but-

If the driving speed is higher than 75 mph
(120 km/h), the vehicle is automatically low-
ered in comfort mode by 0.4 in (10 mm) com-
pared to the normal level.
Load compensation
The vehicle can compensate differences in the
vehicle level by raising or lowering the axles.
4MATIC (permanent four-wheel drive)
4MATIC ensures that all four wheels are perma-
nently driven. Together with ESP®, it improves
the traction of your vehicle whenever a drive
wheel spins due to insufficient grip.
If you fail to adapt your driving style, 4MATIC can
neither reduce the risk of accident nor override
the laws of physics. 4MATIC cannot take
account of road, weather and traffic conditions. 4MATIC is only an aid. You are responsible for
the distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
your lane.
If a drive wheel spins due to insufficient grip:
ROnly depress the accelerator pedal as far as
necessary when pulling away.
RAccelerate less when driving.
!Never tow the vehicle with one axle raised.
This may damage the transfer case. Damage
of this sort is not covered by the Mercedes-
Benz Limited Warranty. All wheels must
remain either on the ground or be fully raised.
Observe the instructions for towing the vehi-
cle with all wheels in full contact with the
ground.
iIn wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if you
use winter tires (M+S tires), with snow chains
if necessary.

Active Parking Assist
General notes
Active Parking Assist is an electronic parking aid
with ultrasound. It measures the road on both
sides of the vehicle. A parking symbol indicates a suitable parking space. Active steering inter-
vention and brake application can assist you
during parking and when exiting a parking
space. You may also use PARKTRONIC
(
Ypage 214).
Important safety notes
Active Parking Assist is merely an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering, parking and exiting a
parking space. Make sure that no persons, ani-
mals or objects are in the maneuvering range.
When PARKTRONIC is switched off, Active Park-
ing Assist is also unavailable.
GWARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
result in a collision with another road user.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
!If unavoidable, you should drive over obsta-
cles such as curbs slowly and not at a sharp
angle. Otherwise, you may damage the
wheels or tires.
Active Parking Assist may possibly indicate
parking spaces which are not suitable for park-
ing, for example:
Rwhere parking or stopping is prohibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces
Parking tips:
ROn narrow roads, drive as close to the parking
space as possible.
RParking spaces that are littered or overgrown
might be identified or measured incorrectly.
RParking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly.
