Starting difficulties
If the engine does not start as described,
carry out the following steps:
If you are starting the engine with the
SmartKey, turn SmartKey in starter
switch to position0 and repeat starting
procedure.

If you are starting the engine with
KEYLESS-GO*: Close any doors that
may be open to allow for better
detection of the SmartKey with
KEYLESS-GO*.
Or:

Remove KEYLESS-GO* start/stop
button from starter switch (
page 41).

Start the engine with the SmartKey as
radio signals from another source may
be interfering with the SmartKey with
KEYLESS-GO*.

Repeat the starting procedure
(page 54). Remember that extended
starting attempts can drain the battery.

Get a jump start (
page 515).
If the engine does not start after several
starting attempts, there could be a mal-
function in the engine electronics or in the
fuel supply system.

Notify an authorized Mercedes-Benz
Light Truck Center.
Parking brake
1Parking brake pedal
2Release handle

Release the parking brake by pulling on
release handle2.
The warning lamp; (USA only)
or3(Canada only) in the
instrument cluster goes out.Warning!
G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Children could release the
parking brake, which could result in an acci-
dent and/or serious injury.

58 Getting startedDrivingDriving off
Depress the brake pedal.
The gear selector lever can now be
used.

Shift automatic transmission toD orR
(page 187).

Release the brake pedal.

Carefully depress the accelerator
pedal.After a cold start, the automatic transmis-
sion shifts at a higher engine revolution.
This allows the catalytic converter (gaso-
line engine) or the oxidation catalyst (die-
sel engine) to reach its operating
temperature earlier.
i
Wait for the gear selection process to com-
plete before setting the vehicle in motion.
i
Shifting from gear positionP to positionR,
N, orD is only possible with the brake pedal
depressed. Without the brake pedal depressed,
the gear selector lever can be moved, but the
parking pawl remains engaged, not allowing
shifting to occur.
!
If you hear a warning signal 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 (
page 57).
i
Once the vehicle is in motion, the automatic
central locking system engages and the locking
knobs drop down.
The automatic door lock feature can be
deactivated (
page 176).
You can open a locked door from the inside.
Open door only when conditions are safe to do
so.
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.Warning!
G
It is dangerous to shift the automatic trans-
mission out ofP orN 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.

!
Do not run cold engine at high engine
speeds. Running a cold engine at high engine
speeds may shorten the service life of the
engine.
ML 63 AMG:
At engine temperatures below 68°F (20°C), the
engine’s maximum speed is restricted in order to
protect it from damage. Avoid driving your vehi-
cle at full speed when the engine is cold to pre-
vent premature engine wear and/or diminished
comfort.
!
Simultaneously depressing the accelerator
pedal and applying the brake reduces engine
performance and causes premature brake and
drivetrain wear.

a dry windshield. If it is necessary to operate the
windshield wipers in dry weather conditions,
always operate the windshield wipers with wind-
shield washer fluid (
