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.

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 may result in serious
personal injury or damage to the vehicle or
vehicle drivetrain. Therefore, always do the
following before turning off the engine and

park position P automatically when
R you open the driver’s door while driving
at low speed, and
R the automatic transmission is in drive
position D or reverse gear R
After the vehicle has engaged park position
P automatically, you can engage drive
position D or reverse gear R again to
override this locking feature purposely.
i The gear selector lever always returns to
its original position.

covered by the Mercedes-Benz Limited
Warranty.
! Because the ESP ®
operates
automatically, the engine and ignition must
be shut off (SmartKey in starter switch
position 0 or 1 or KEYLESS-GO start/stop
button in position 0 or 1) when the parking
brake is being tested on a brake test
dynamometer. Such testing should be no
longer than 10 seconds.
Active braking action through the ESP ®
may otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.
LOW RANGE mode
The LOW RANGE mode is available on
vehicles with enhanced off-road package.
In the following situations you should switch
to the LOW RANGE mode:
R during off-road driving
R before driving through water
R when towing up or down on steep gradients
With LOW RANGE selected, the engine’s
power delivery and the shifting behavior of
the automatic transmission are adjusted.
Furthermore, the ABS, the ESP ®
, and the
4-ETS functions especially adapted to off-
road travel are activated.
For more information on off-road driving, see
“Off-road driving” ( Y page 262).
For information on driving safety systems
during LOW RANGE mode, see “Driving safety
systems” ( Y page 61).
Gear ranges
There are two possible settings.
HIGH
RANGERoad position for all normal
driving situations.
(LOW RANGE mode off)LOW
RANGEOff-road position for
traveling on rough terrain.
(LOW RANGE mode on)
Also use the off-road
position when driving on-
road on steep gradients,
especially when towing a
trailer.
LOW RANGE acts by raising
the engine’s gear ratio. The
vehicle travels at roughly
third the speed compared to
when in HIGH RANGE
position, leading to an
increase in the engine’s
drive power.GWarning!
Always wait until the procedure of shifting
from HIGH RANGE to LOW RANGE – and from
LOW RANGE to HIGH RANGE – has been
entirely completed. During this procedure do
not turn off the engine or shift the automatic
transmission into another gear.
If you do not wait until the shifting procedure
has been entirely completed then it might not
be correctly performed. The transfer case
might be in neutral, thus interrupting the
transfer of power between the engine and the
drive axle.
The vehicle is then freely movable, even if a
gear has been selected, and could
unintentionally be set into motion –
particularly on up – or downhill grades. This
could lead to an accident and cause injury to
yourself and others.
Please observe related messages appearing
in the multifunction display.

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†).
