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 278).
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.

a winter front or bug cover. Otherwise the
readings of the on-board diagnostic system
may be inaccurate. Some of theses
readings are required by law and must be
accurate at all times.
Engine oil
The amount of oil your engine consumes will
depend on a number of factors, including
driving style. Increased oil consumption can
occur when the vehicle is new or the vehicle
is driven frequently at higher engine speeds.
Engine oil consumption checks should only
be made after the vehicle break-in period.
! Do not use any special lubricant additives,
as these may damage the drive assemblies.
Using special additives not approved by
Mercedes-Benz may cause damage not
covered by the Mercedes-Benz Limited

! Simultaneously depressing the
accelerator pedal and applying the brakes
reduces engine performance and causes
premature brake and drivetrain wear which
is not covered by the Mercedes-Benz
Limited Warranty.
Hydroplaning
Depending on the depth of the water layer on
the road, hydroplaning may occur, even at low
speeds and with new tires. In heavy rain or
when conditions indicate possible
hydroplaning:
XReduce vehicle speed.XAvoid track grooves in the road.XApply brakes cautiously.
Standing water
! Do not drive through flooded areas.
Before driving through water, determine its
depth.
If you must drive through standing water,
drive slowly to prevent water from entering
the passenger compartment or the engine
compartment. Water in these areas could
cause damage to electrical components or
wiring of the engine or transmission, or
could result in water being ingested by the
engine through the air intake causing
severe internal engine damage. Any such
damage is not covered by the Mercedes-
Benz Limited Warranty.
i Select the raised level ( Y page 159)
before driving through standing water.
For more information, see “Driving through
water” ( Y page 266).
Off-road drivingGWarning!
Do not load items on the crossbars. It may
cause instability during some maneuvers
which could result in an accident.
Drive slowly in unknown terrain. This will
make it easier to recognize unexpected
obstacles and avoid damage to the vehicle.
To help avoid the vehicle rolling over, never
turn it around on steep inclines. If the vehicle
cannot complete the attempted climb, back it
down in reverse gear.
Do not drive along the side of a slope. The
vehicle might otherwise rollover. If in doing so
the vehicle begins to show a tendency to roll,
immediately steer into a line of gravity
(straight up or downhill).
Never let the vehicle roll backwards in idle.
You may lose control of the vehicle if you use
only the service brake. For information on
driving downhill, see “Driving downhill”.
GWarning!
Sand, dirt, mud and other material having
friction property can cause exceptional wear
and tear as well as brake failure.
Have the brakes checked for dirt build-up and
cleaned. There is otherwise a risk that full
braking power may not be available in an
emergency.
GWarning!
Please be aware that by raising the vehicle
level, the center of gravity also rises.
Therefore, always ensure that the vehicle
level is as low as possible. With higher ride
height the ESP ®
may activate earlier in certain
situations.
Read this chapter carefully before you begin
off-road travel.
Familiarize yourself with the vehicle
characteristics and gear changing before you
attempt any difficult terrain off-road driving.
