The automatic central locking function can
be switched off ( Y page 135).

! Only shift the manual transmission into
reverse gear R when the vehicle is stopped.
Otherwise the manual transmission could
be damaged.
XShift the manual transmission into 1st gear
or reverse gear R.XIf engaged, release the parking brake.XRelease the brake pedal.XSimultaneously slowly release the clutch
pedal and carefully depress the accelerator
pedal.
! Avoid driving at excessive engine speeds.
This may result in serious engine damage
that is not covered by the Mercedes-Benz
Limited Warranty.
Shift gear in a timely manner.
For more information on driving, see “Driving
instructions” ( Y page 254).
Automatic transmission
GWarning!
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 254).
Problems while driving
The engine runs erratically and misfires
R An ignition cable may be damaged.
R The engine electronics may not be
operating properly.
R Unburned gasoline may have entered the
catalytic converter and damaged it.
XGive very little gas.XHave the problem checked at an authorized
Mercedes-Benz Center as soon as possible.
The coolant temperature is above
248‡ (120†)
The coolant is too hot and is no longer cooling
the engine.
XStop the vehicle in a safe location as soon
as possible.XTurn off the engine immediately.104Driving and parkingControls in detail

XAllow the engine and coolant to cool off.XCheck the coolant level and add coolant if
necessary ( Y page 227).
In case of accident
If the vehicle is leaking fuel:
XDo not start the engine under any
circumstances.XExit the vehicle at a safe distance from the
roadway.XNotify local fire and/or police authorities.
If the extent of the damage cannot be
determined:
XContact an authorized Mercedes-Benz
Center or call Roadside Assistance.
If no damage on major assemblies, fuel
system, and engine mount can be
determined:
XStart the engine in the usual manner.
Parking
GWarning!
Do not park this vehicle in areas where
combustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system. These materials could be
ignited and cause a vehicle fire.
Vehicle movement can cause serious
personal injury or damage to the vehicle or
the vehicle drivetrain. Therefore, always do
the following before turning off the engine and
leaving the vehicle:
R Keep right foot on the brake pedal.
R Engage the parking brake.
R Manual transmission: Shift the manual
transmission into 1st gear or reverse gear
R .
R
Automatic transmission: Shift the
automatic transmission into park position
P .
R Slowly release the brake pedal.
R When parked on an incline, always turn the
front wheels towards the road curb.
R Turn the SmartKey in the starter switch to
position 0 and remove the SmartKey from
the starter switch, or press the KEYLESS-
GO start/stop button.
R Take the SmartKey with you and lock the
vehicle when leaving.GWarning!
Manual transmission:
Wait until the vehicle is stationary before
removing the SmartKey from the starter
switch. The vehicle cannot be steered when
the SmartKey is removed from the starter
switch.
Parking brake
GWarning!
Engaging the parking brake while the vehicle
is in motion can cause the rear wheels to lock
up. You could lose control of the vehicle and
cause an accident. In addition, the vehicle’s
brake lights do not light up when the parking
brake is engaged.
GWarning!
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it with
you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children could
release the parking brake and/or shift the
automatic transmission out of park position
P (manual transmission: shift into the neutral
position), either of which could result in an
accident and/or serious personal injury.

Driving characteristics may be impaired.
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
(Y page 148) or with the COMAND system.
Vehicles with COMAND system: Refer to
separate operating instructions.

XTo brighten illumination: Turn
dimmer : clockwise.
XTo dim illumination: Turn dimmer :
counterclockwise.
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.

Engine compartment
Hood
GWarning!
Do not pull the release lever while the vehicle
is in motion. Otherwise the hood could be
forced open by passing air flow.
This could cause the hood to come loose and
injure you and/or others.
Opening
GWarning!
Do not open the hood when the engine is
overheated. You could be seriously injured.
Observe the coolant temperature gauge to
determine whether the engine may be
overheated. If you see flames or smoke
coming from the engine compartment, move
away from the vehicle. Wait until the engine
has cooled. If necessary, call the fire
department.
GWarning!
You could be injured when the hood is open –
even when the engine is turned off.
Parts of the engine can become very hot. To
prevent burns, let the engine cool completely
before touching any components on the
vehicle. Comply with all relevant safety
precautions.
GWarning!
To help prevent personal injury, stay clear of
moving parts when the hood is open and the
engine is running.
The radiator fan may continue to run for
approximately 30 seconds or may even
restart after the engine has been turned off.
Stay clear of fan blades.
