When the OCS senses that the front
passenger seat occupant is classified as
being up to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 42 indicator lamp
will illuminate when the engine is started and
remain illuminated, indicating that the front
passenger front air bag is deactivated.
When the OCS senses that the front
passenger seat is classified as being empty,
the 42 indicator lamp will
illuminate when the engine is started and
remain illuminated, indicating that the front
passenger front air bag is deactivated.
When the OCS senses that the front
passenger seat occupant is classified as
being heavier than the weight of a typical
12-month-old child seated in a standard child
restraint or as being a small individual (such
as a young teenager or a small adult), the
42 indicator lamp will illuminate
for approximately 6 seconds when the engine
is started and then, depending on occupant
weight sensor readings from the seat, remain
illuminated or go out. With the
42 indicator lamp illuminated,
the front passenger front air bag is
deactivated. With the 42
indicator lamp out, the front passenger front
air bag is activated.
When the OCS senses that the front
passenger seat occupant is classified as an
adult or someone larger than a small
individual, the 42 indicator lamp
will illuminate for approximately 6 seconds
when the engine is started and then goes out,
indicating that the front passenger front air
bag is activated.
If the 42 indicator lamp is
illuminated, the front passenger front air bag
is deactivated and will not be deployed.If the 42 indicator lamp is not
illuminated, the front passenger front air bag
is activated and will be deployed
R in the event of certain frontal impacts
R if impact exceeds a preset deployment
threshold
R independently of the side impact air bags
If the front passenger front air bag is
deployed, the rate of inflation will be
influenced by
R the rate of relevant vehicle deceleration as
assessed by the air bag control unit
R the front passenger’s weight category as
identified by the OCS
For more information on air bag display
messages in the multifunction display, see
( Y page 275).GWarning!
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommend that
children be placed in the rear seats whenever
possible. Regardless of seating position,
children 12 years old and under must be
seated and properly secured in an appropriate
infant restraint, toddler restraint, or booster
seat recommended for the size and weight of
the child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt, the seat
belt and top tether strap, or lower anchors and
top tether strap, fully in accordance with the
child seat manufacturer’s instructions.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.

iAt low ambient temperatures, the exterior
rear view mirrors will be heated
automatically.
Auto-dimming rear view mirrors
The exterior rear view mirror on the driver’s
side and the interior rear view mirror will
respond automatically to glare when the
ignition is switched on and incoming light
from headlamps falls on the sensor in the
interior rear view mirror.
The rear view mirrors will not react if the
automatic transmission is set to reverse gear
R or the interior lighting is switched on.
GWarning!
The auto-dimming function does not react if
incoming light is not aimed directly at sensors
in the interior rear view mirror.
The interior rear view mirror and the exterior
rear view mirror on the driver’s side do not
react, for example, when transporting cargo
which covers the rear window.
Light hitting the mirror(s) at certain angles
(incident light) could blind you. As a result,
you may not be able to observe traffic
conditions and could cause an accident.

GWarning!
If a drive wheel is spinning due to insufficient
traction:
RWhile driving off, apply as little throttle as
possible.
RWhile driving, ease up on the accelerator
pedal.
RAdapt 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.
iIn winter operation, the maximum
effectiveness of the 4MATIC is only
achieved with winter tires (Y page 242) or
snow chains as required.
Parktronic system
The Parktronic system 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
Ryou switch on the ignition
and
Ryou release the parking brake
and
Rthe automatic transmission is in 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 parking brake.
The Parktronic system monitors the
surroundings of your vehicle with six sensors
in the front bumper and four sensors in the
rear bumper.
To function properly, sensors : must be free
of dirt, ice, snow and slush. Clean
sensors : regularly. Be careful not to
scratch or damage sensors :, see “Cleaning
the driving systems sensors” (Y page 263).
GWarning!
The Parktronic is a supplemental system. It is
not intended to, nor does it replace, the need
for extreme care. The responsibility during
parking and other critical maneuvers always
remains with the driver.

GWarning!
Make sure no persons or animals are in or
near the area in which you are parking/
maneuvering. Otherwise, they could be
injured.
! 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.
During parking maneuvers, pay special
attention to objects located above or below
the height of the sensors (e.g. street curbs,
painted posts, or trailer hitches etc.). The
Parktronic system will not detect such
objects at close range and damage to your
vehicle or the object may result.
! Ultrasonic signals from outside sources
(e.g. truck air brakes, car wash, or
jackhammers) may impair the operation of
the Parktronic system.
Range of the sensors
Front sensors
Centerapprox. 40 in (100 cm)Cornersapprox. 24 in (60 cm)
Rear sensors
Centerapprox. 48 in (120 cm)Cornersapprox. 32 in (80 cm)
Minimum distance
Centerapprox. 8 in (20 cm)Cornersapprox. 6 in (15 cm)
If the Parktronic system detects an obstacle
in this range, all the distance warning
segments illuminate and you hear a warning
signal. If the obstacle is closer than the
minimum distance, the actual distance may
no longer be indicated by the Parktronic
system.
Warning indicators
Visual signals indicate the relative distance
between the sensors and an obstacle.
