On slippery road surfaces, never downshift in
order to obtain braking action. This could
result in drive wheel slip and reduced vehicle
control. Your vehicle’s ABS will not prevent
this type of loss of control.
! Do not run a cold engine at high engine
speeds. Running a cold engine at high
engine speeds may shorten the service life
of the engine. This is not covered by the
Mercedes-Benz Limited Warranty.
! If an acoustic warning sounds and the
message Release Parking Brake
appears in the multifunction display when
driving off, you have forgotten to release
the parking brake.
Release the parking brake.
! Avoid spinning of a drive wheel. This may
cause serious damage to the drivetrain
which is not covered by the Mercedes-Benz
Limited Warranty.
! 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.
i Once the vehicle is in motion, the
automatic central locking function engages
and the locking knobs in the doors move
down.
The automatic central locking function can

Automatic transmission
Introduction
For information on driving with an automatic
transmission, see “Driving and parking”
(Y page 98).
GWarning!
Make sure absolutely no objects are
obstructing the pedals’ range of movement.
Keep the driver’s footwell clear of all
obstacles. If there are any floormats or
carpets in the footwell, make sure the pedals
still have sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between or
under the pedals. You could then no longer
brake or accelerate. This could lead to
accidents and injury.
! Allow the engine to warm up under low
load use. Do not place full load on the
engine until the operating temperature has
been reached.
Avoid spinning of a drive wheel for an
extended period when driving off on
slippery road surfaces.
This may cause serious damage to the
engine and the drivetrain which is not
covered by the Mercedes-Benz Limited
Warranty.
iDuring the brief warm-up, transmission
upshifting is delayed. This allows the
catalytic converter to heat up more quickly
to operating temperature.

If you must continue to drive, do so with added
caution. Contact an authorized Mercedes-
Benz Center as soon as possible.
The language setting for the multifunction
display can be changed with the audio system

XTo dim illumination: Turn dimmer :

iThe instrument cluster illumination is
dimmed or brightened automatically to suit
ambient light conditions.
The instrument cluster illumination will also
be adjusted automatically when you switch
on the vehicle’s exterior lamps.
Coolant temperature gauge
The coolant temperature gauge is located on
the left side in the instrument cluster
(Y page 28).
GWarning!
Driving when your engine is overheated can
cause some fluids which may have leaked into
the engine compartment to catch fire. You
could be seriously burned.
Steam from an overheated engine can cause
serious burns which can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until
the engine has cooled down.
During severe operating conditions, e.g. stop-
and-go traffic, the coolant temperature may
rise close to 248‡ (120†), i.e close to the
red zone of the temperature gauge.
! Excessive coolant temperature triggers a
warning in the multifunction display.
The engine should not be operated with a
coolant temperature above 248‡ (120†),
i.e. in the red zone of the coolant
temperature gauge. Doing so may cause
serious engine damage which is not
covered by the Mercedes-Benz Limited
Warranty.
Tachometer
The red marking on the tachometer
(Y page 28) denotes excessive engine speed.
! Avoid driving at excessive engine speeds,
as it may result in serious engine damage
that is not covered by the Mercedes-Benz
Limited Warranty.
To help protect the engine, the fuel supply is
interrupted if the engine is operated within
the red marking.
