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
be switched off ( Y page 111).
Automatic transmissionGWarning!
It is dangerous to shift the automatic
transmission out of park position P or neutral
position N if the engine speed is higher than
idle speed. If your foot is not firmly on the
brake pedal, the vehicle could accelerate
quickly forward or in reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the
engine is idling normally and when your right
foot is firmly on the brake pedal.
! Only shift the automatic transmission into
reverse gear R or park position P when the
vehicle is stopped. Otherwise the
automatic transmission could be damaged.
XDepress the brake pedal.
The gear selector lever lock is released.XShift the automatic transmission into drive
position D or reverse gear R.i
Shifting the automatic transmission out of
park position P is only possible with the
brake pedal depressed.
Only depressing the brake pedal releases
the gear selector lever lock.XWait for the gear selection process to
complete before setting the vehicle in
motion.XIf engaged, release the parking brake.XRelease the brake pedal.XCarefully depress the accelerator pedal.
After a cold start, the automatic transmission
shifts at a higher engine speed. This allows
the catalytic converter to reach its operating
temperature earlier.
For more information on driving, see “Driving
instructions” ( Y page 181).
For information on off-road driving, see “Off-
road driving” ( Y page 184).
Problems while driving

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†).
! 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.

( Y page 26) 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.
Control system
Introduction
The control system is activated as soon as the
starter switch is in position 1.
The control system enables you to call up
information about your vehicle and to change
vehicle settings.
For example, you can use the control system
to find out when your vehicle is next due for
maintenance service, to set the language for
messages in the instrument cluster display,
and much more.
GWarning!
A driver’s attention to the road and traffic
conditions must always be his/her primary
focus when driving.
For your safety and the safety of others,
selecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions permit
it to be done safely.
