A driver’s attention to the road and traffic
conditions must always be his /her primary
focus when driving.
For your safety and the safety of others, se-
lecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions per-
mit it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 13.5 m) every second.

A driver’s attention to the road and traffic
conditions must always be his/her primary
focus when driving. For your safety and the
safety of others, we recommend that you
pull over to a safe location and stop before
placing or taking a telephone call. If you
choose to use the telephone while driving,
please use the hands-free device and only
use the telephone when weather, road and
traffic conditions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a ve-
hicle.

140 Controls in detailAutomatic transmission
Automatic transmissionFor more information on driving with an au-
tomatic transmission, see the “Getting
started” section (
page 43).
Your vehicle’s transmission adapts its gear
shifting process to your individual driving
style by continually adjusting the shift
points up or down. These shift point adjust-
ments are performed based on current op-
erating and driving conditions.
If the operating conditions change, the au-
tomatic transmission reacts by adjusting
its gear shift program.The automatic transmission selects indi-
vidual gears automatically, dependent
upon
the gear selector lever positionD with
gear ranges4, 3, 2, 1 (
page 142)
transfer case position (HIGH or LOW)
the position of the accelerator pedal
(page 144)
the vehicle speed
The current gear selector lever position
and the transfer case position (HIGH or
LOW) appear in the multifunction display.

2Gear selector lever position/gear
range When the gear selector lever is in
positionD, you can influence transmission
shifting by
limiting the gear range
changing gears manually
iDuring the brief warm-up, transmission
upshifting is delayed. This allows the
catalytic converter to heat up more
quickly to operating temperature.
Warning!
G
It is dangerous to shift the gear selector
lever 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 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.

Automatic transmission
One-touch gearshifting
Even with an automatic transmission, you
can change the gears manually when the
gear selector lever is in positionD.
Downshifting
Briefly press the gear selector lever to
the left in the D–direction.
The transmission will shift from the current
gear to the next lower gear. This action si-
multaneously limits the gear range of the
transmission (
page 142).Upshifting
Briefly press the gear selector lever to
the right in the D+direction.
The transmission will shift from the current
gear to the next higher gear as permitted
by the shift program. This action simulta-
neously extends the gear range of the
transmission.Canceling gear range limit
Press and hold the gear selector lever
in the D+direction until
Dreappears in
the multifunction display.
The transmission will shift from the current
gear range directly to gear rangeD.
Shifting into optimal gear range
Press and hold the gear selector lever
in the D-direction.
The transmission will automatically select
the gear range suited for optimal accelera-
tion and deceleration. This will involve
shifting down one or more gears.
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.
iTo avoid overrevving the engine when
the gear selector lever is moved to the
D- direction, the transmission will not
shift to a lower gear if the engine’s
max. speed would be exceeded.

EffectThe SmartKey can only be
removed from the starter switch
with the gear selector lever in
positionP. With the SmartKey
removed, the gear selector lever
is locked in positionP.
If the vehicle’s electrical system
is malfunctioning, the gear
selector lever could remain
locked in positionP

No power is transmitted from the
engine to the drive axle. When
the brakes are released, the
vehicle can be moved freely
(pushed or towed).
Do not engageN while driving
except:
to coast when vehicle is in
danger of skidding (e.g. on
icy roads) when the ESP is
deactivated or malfunction-
ing

ê
Drive
The transmission shifts
automatically. All five forward
gears are available.
!Coasting the vehicle, or driving for any
other reason with gear selector lever
inN can result in transmission damage
that is not covered by the
Mercedes-Benz Limited Warranty.Warning!
G
Getting out of your vehicle with the gear se-
lector lever not fully engaged in positionP is
dangerous. Also, positionP alone is not in-
tended to or capable of preventing your ve-
hicle from moving, possibly hitting people or
objects.
Always set the parking brake in addition to
shifting to positionP (
page 51).
When parked on an incline, turn the front
wheels towards the road curb.
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
144 Controls in detailAutomatic transmission
Accelerator position
Your driving style influences the transmis-
sion’s shifting behavior:
Less throttle Earlier upshifting
More throttle Later upshifting
Kickdown
Use kickdown when you want maximum
acceleration.
Press the accelerator past the point of
resistance.
The transmission shifts into a lower
gear.
Ease on the accelerator when you have
reached the desired speed.
The transmission shifts up again.Emergency operation (Limp Home
Mode)
If vehicle acceleration worsens or the
transmission no longer shifts, the trans-
mission is most likely operating in limp
home (emergency operation) mode. In this
mode, only 2nd gear and reverse gear can
be activated.
Stop the vehicle.
Move gear selector lever toP.
Turn off the engine.
Wait at least ten seconds before re-
starting.
Restart the engine.
Move gear selector lever to positionD
(for second gear) orR.
Have the transmission checked at an
authorized Mercedes-Benz Light Truck
Center as soon as possible.
Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, and lock
the vehicle. Do not leave children unattend-
ed in the vehicle, or with access to an un-
locked vehicle. Children could move the
gear selector lever from positionP, which
could result in an accident and/or serious
personal injury.
