COMFORT appears in the multifunction
display. 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 59) and the Electronic Traction
System (ETS/4-ETS) (Y page 60). G
Warning!
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 395) 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
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 Driving systems

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 406). G
Warning!
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. G
Warning!
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.

When traveling in Canada in a vehicle not
registered in Canada, you must switch off the
radar sensor system ( Y page 216). Canadian
law does not permit the use of the radar
sensor system for vehicles from outside of
Canada. When you switch off the radar sensor
system, the following functions are

! The operational function of the Park
Assist can be affected by dirty sensors,
especially at times of snow and ice.
Make sure that the area on the bumpers
around the sensors is free of dirt, ice and/
or slush, otherwise the Park Assist may not
function properly.
For cleaning the driving systems sensors, see
(Y page 406).
! High-frequency sources such as toll
stations, speed measuring systems, etc.
can cause the Park Assist to malfunction.
You can switch off the Park Assist using the
Park Assist button or switch off the radar
sensors with the instrument cluster control
system to prevent possible malfunction.
The Park Assist is an electronic parking aid
with radar sensors that helps you while
parking. It visually and audibly indicates the
relative distance between the vehicle and an
obstacle.
The Park Assist is automatically activated
when the engine is running and the automatic transmission is in drive position D, reverse
gear
R or neutral position N.
The Park Assist deactivates at speeds over
approximately 10 mph (16 km/h). At lower
speeds the Park Assist turns on again.
The Park Assist is also switched off when you
set the automatic transmission into park
position P or switch off the engine.
While the automatic transmission is in neutral
position N, the Park Assist is switched off if
you secure the vehicle in place with the
electronic parking brake.
The Park Assist monitors the surroundings of
your vehicle with four sensors in the front
bumper and two sensors in the rear bumper.
Range of the sensors The sensors of the Park Assist are integrated
in the front and rear bumpers. Make sure that
the bumpers are clear of dirt, ice and slush in
the area of the sensors, as otherwise, the
Park Assist may not function properly, see
(Y page 406). Driving systems

The sensors have a broad detection
range. Therefore, the Park Assist may also
issue warnings due to detected obstacles
on the ground, for example:
R Sewer canal covers
R Rails
R Bumps
R Gutters
Warnings may also be issued due to
obstacles that are moving up quickly, for
example rolling garage doors.

While parking, pay particular attention to
objects over or underneath the sensors,
e.g. flower boxes, an elevated crossbar or
a trailer tow hitch. The Park Assist does not
detect such nearby objects. You could
otherwise damage the vehicle or the
objects.

Once the second red distance segment
illuminates, you will hear a continuous
warning tone. You have reached the minimum
distance. The signal is canceled when the
automatic transmission is in park position P
or neutral position N with the electronic
parking brake engaged.

Once the second red distance segment
illuminates, you will hear a continuous

electronic parking brake engaged.
i During strong rainfall, the warning
indicators and warning tones may be
triggered, for example, by water splashing
into the area of the sensors.
Collision warning The Park Assist can detect obstacles from a
considerable distance. If you drive in reverse
towards an obstacle, you will hear a warning
tone. You must then brake in order to avoid a
collision. The warning tone for a collision will
not sound when the vehicle is at a standstill
very close to the obstacle. In this case, you
will hear a corresponding tone for the warning
indicator in the rear area.

During strong rainfall, the collision
warning may be triggered, for example, by

The Advanced Parking Guidance is an
electronic parking aid equipped with radar
sensors. The radar sensors scan the area on
both sides of vehicle. When a suitable parking
space is found, it is indicated by a parking
space symbol in the multifunction display.
You will receive steering instructions for
parking in that space. G
Warning!
The Advanced 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 Advanced Parking Guidance only shows a

to the parking space are
not taken into account, e.g. if the position of
the vehicle parked in front of or behind the
space changes or objects in the parking space

Advanced Parking Guidance does not relieve
you of the responsibility to pay attention. If
you only rely on the Advanced Parking

injure yourself and others.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
maneuvering. G
Warning!
Make sure no persons or animals are in the
area in

which you are maneuvering. You could
otherwise injure them.
