GWarning!
As long as the SmartKey is in your vehicle, the
vehicle can be started. Therefore, never leave
children unattended in the vehicle, as they
could otherwise accidentally start the engine.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Do
not leave children unattended in the vehicle,
or with access to an unlocked vehicle. A
child’s unsupervised access to a vehicle could
result in an accident and/or serious personal
injury.
You can start your vehicle without the
SmartKey in the starter switch using the
KEYLESS-GO start/stop button.
The SmartKey must be located in the vehicle.

Starting difficulties
! Remember that extended starting
attempts can drain the battery.
The engine does not start. You can hear
the starter.
There could be a malfunction in the engine
electronics or in the fuel supply system.
Carry out the following steps:
XIf you are starting the engine with the
SmartKey: Turn the SmartKey in the starter
switch to position 0 and repeat the starting
procedure.XIf you are starting the engine with KEYLESS-
GO: Close any doors that may be open to
allow for better detection of the SmartKey.
or
XRemove the KEYLESS-GO start/stop
button from the starter switch.XStart the engine with the SmartKey as radio
signals from another source may be
interfering with the KEYLESS-GO function.XRepeat the starting procedure.
If the engine does not start after several
starting attempts:
XContact an authorized Mercedes-Benz
Center or call Roadside Assistance.The engine does not start. You cannot
hear the starter.
The battery may not be charged sufficiently.XGet a jump start ( Y page 350).
If the engine will not start despite a jump
start:
XContact an authorized Mercedes-Benz
Center or call Roadside Assistance.
The starter has been exposed to excessive
temperatures.
XLet the starter cool for about 2 minutes.XRepeat the starting procedure.
If the engine does not start after several
starting attempts:
XContact an authorized Mercedes-Benz
Center or call Roadside Assistance.
Driving off
GWarning!
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
be switched off ( Y page 138).
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 can now be used.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.
Without the brake pedal depressed, the
gear selector lever can be moved up or
down. However, the parking pawl remains
engaged, not allowing shifting to occur.
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 (gasoline engine) or
the oxidation catalyst (diesel engine) to reach
its operating temperature earlier.
For more information on driving, see “Driving
instructions” ( Y page 259).
For information on off-road driving, see “Off-
road driving” ( Y page 262).
Problems while driving
The engine runs erratically and misfires
R Gasoline engine: An ignition cable may be
damaged.
R The engine electronics may not be
operating properly.
R Gasoline engine: 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.XAllow the engine and coolant to cool off.XCheck the coolant level and add coolant if
necessary ( Y page 231).Driving and parking111Controls in detailX164_AKB; 5; 31, en-USd2ureepe,Version: 2.11.8.12009-09-11T12:30:16+02:00 - Seite 111Z

Automatic transmission
Introduction
For information on driving with an automatic
transmission, see “Driving and parking”
(Y page 108).
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 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 (gasoline engine) or
oxidation catalyst (diesel engine) to heat up
more quickly to operating temperature.

Checking coolant temperature
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.
XPress button & or * repeatedly until
the coolant temperature appears in the
multifunction display.
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†). Doing so may cause serious
engine damage which is not covered by the
Mercedes-Benz Limited Warranty.
Calling up digital speedometer or
outside temperature
You can select whether the digital
speedometer or the outside temperature
appears in the multifunction display
(Y page 135).
GWarning!
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
XPress button & or * repeatedly until
the digital speedometer or the outside
temperature appears in the multifunction
display.
