Safety notes
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.
GWarning!
With the engine not running, there is no power
assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle. Adapt your driving accordingly.
Starting the engine
GWarning!
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and possible death.
Do not run the engine in confined areas (such
as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are
entering the vehicle while driving, have the
cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one
window fully open at all times.

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.

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.

vehicle is stopped. Otherwise the
automatic transmission could be damaged.

Introduction
For information on driving with an automatic
transmission, see “Driving and parking”
(Y page 85).
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.

quickly forward or in reverse. You could lose
control of the vehicle and hit someone or

vehicle is stopped. Otherwise the
automatic transmission could be damaged.
iShifting 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.
iThe current gear selector lever position
corresponds with the current transmission
position.
The current transmission position P, R, N,
or D appears in the multifunction display
(Y page 90).
GWarning!
Keep in mind that turning off the engine alone
only will shift the automatic transmission into
neutral position N automatically.
Always shift the automatic transmission into
park position P before turning off the engine.
Otherwise the vehicle could roll away which
could result in an accident and/or serious
personal injury.
iMoving the gear selector lever up or down
shifts the automatic transmission out of
park position P.
Shifting procedure

gears automatically, depending onRthe selected gear range (Y page 92)

Extending gear rangeXBriefly press the gear selector lever to the
right in the D+ direction.
The automatic transmission will shift into
the next higher gear as permitted by the
shift program. This action simultaneously
extends the gear range of the automatic
transmission.
i If you press on the accelerator pedal
when the engine has reached the
revolution limit of the current gear range,
the automatic transmission will upshift
beyond any gear range limit selected.
Canceling gear range limit
XPress and hold the gear selector lever to
the right in the D+ direction until D
reappears in the multifunction display.
The automatic transmission will shift from
the current gear range directly into drive
position D.
Shifting into optimal gear range
XPress and hold the gear selector lever to
the left in the D- direction.
The automatic transmission will select the
gear range suited for optimal acceleration
and deceleration automatically. This will
involve shifting down one or more gears.
Emergency operation (limp-home
mode)
If vehicle acceleration becomes less
responsive or sluggish or the automatic
transmission no longer shifts, the automatic
transmission is most likely operating in limp-
home (emergency operation) mode. In this
mode only second gear and reverse gear R
can be selected.

Switching transfer case
Transfer case switch
The transfer case switch is located on the
lower part of the center console.

GWarning!
Always wait until the procedure of shifting
from HIGH to LOW – and from LOW to HIGH
– 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

fouled surfaces
! Do not switch the front axle differential
lock when driving around tight corners. This
restricts steering ability.
! When driving off-road, apply only
moderate pressure to the accelerator pedal
if the differential locks are switched on.
When operating the vehicle on a single-axle
dynamometer – no matter how briefly – you
must
R raise the axle not being driven
