You could jeopardize the operating safety of
your vehicle if you use parts, tires and wheels
as well as accessories relevant to safety
which have not bee napproved by Mercedes.
This could lead to malfunctions in safety-
relevant systems, e.g. the brake system .Use
only genuine Mercedes-Benz parts or parts of
equal quality. Only use tires, wheels and
accessories that have been specifically
approved for your vehicle.
Genuine Mercedes-Benz parts are subject to
strict quality control. Every part has been
specifically developed, manufactured or
selected for and adapted to Mercedes-Benz
vehicles. Only genuine Mercedes-Benz parts
should therefore be used.
More than 300,000 different genuine
Mercedes-Benz parts are available for
Mercedes-Benz models.
All authorized Mercedes-Benz Centers
maintain a supply of genuine Mercedes-Benz
parts for necessary service and repair work.
In addition, strategically located parts
delivery centers provide quick and reliable
parts service.
Always specify the vehicle identification
number (VIN) (Y page 442) and the engine
number (Y page 443) when ordering genuine
Mercedes-Benz parts. Operator's Manual

Introduction

networked components. In particular,
systems relevant to safety could also be
affected. As a result, these may no longer
functio nas intended and/or jeopardize the
operating safety of the vehicle. There is an
increased risk of an accident and injury.
Never tamper with the wiring as well as
electronic components or their software. You
should have all work to electrical and
electronic equipment carried out at a qualified
specialist workshop.
! There is a risk of damage to the vehicle if:
R the vehicle becomes stuck, e.g. on a high
curb or an unpaved road
R you drive too fast over an obstacle, e.g.
a curb or a hole in the road
R a heavy object strikes the undercarriage
or parts of the chassis.
In situations like this, the body, the
undercarriage, chassis parts, wheels or
tires could be damaged without the
damage being visible. Components
damaged in this way can unexpectedly fail
or, in the case of an accident, no longer
withstand the strain they are designed to.
If the underbody paneling is damaged,
combustible materials such as leaves,
grass or twigs can gather between the
underbody and the underbody paneling. If
these materials come in contact with hot
parts of the exhaust system for an
extended period, they can catch fire.
Have the vehicle checked and repaired
immediately at a qualified specialist
workshop. If on continuing your journey
you notice that driving safety is impaired,
pull over and stop the vehicle immediately,
paying attention to road and traffic
conditions. In such cases, visit a qualified
specialist workshop. Declarations of conformity

WARNING
If you connect equipment to the diagnostics
connection in the vehicle, it may affect the
operation of the vehicle systems. As a result,
the operating safety of the vehicle could be
affected. There is a risk of an accident.
Do not connect any equipment to a
diagnostics connection in the vehicle. G

Drive
The automatic transmission
changes gear automatically. All
forward gears are available.
Changing gear
The automatic transmission shifts to the
individual gears automatically when it is in
transmission position D.This automatic
gearshifting behavior is determined by:
R the position of the accelerator pedal
R the road speed Driving tips
Kickdown Use kickdown for maximum acceleration:
X
Depress the accelerator pedal beyond the
pressure point.
The automatic transmission shifts to a
lower gear depending on the engine speed.
X Ease off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up.
Rocking the vehicle free Shifting the transmission repeatedly between
gears
Dand Rmay help to free the vehicle if
it has become stuck in slush or snow. The
vehicle's engine management system limits
the speed to a maximum of 5 mph (9 km/h)
when shifting back and forth. To shift back
and forth between transmission positions D
and R, move the selector lever up and down
beyond the pressure point.

R comfort-oriented engine and automatic
transmissio nsettings
R optimal fuel consumption resulting from
the automatic transmission shifting up
sooner
R the vehicle pulling away more gently in
forward and reverse gears, unless the
accelerator pedal is depressed fully
R increased sensitivity. This improves driving
stability on slippery road surfaces, for
example
R the automatic transmission shifting up
