Shifting from P to N
Moving the gear selector lever up or down
shifts the automatic transmission out of
park positionP:
With the vehicle at a standstill, depress
the brake pedal and keep it pressed.
Move gear selector lever up or down to
resistance point to select neutral
positionN.Shifting from N to R or from N to D
With the vehicle at a standstill, depress
the brake pedal and keep it pressed.
Move gear selector lever up past the re-
sistance point to select reverse gearR.
or
Move gear selector lever down past the
resistance point to select drive
positionD.
Release the parking brake (page 60).
Release the brake pedal.
Carefully depress the accelerator pedal
to drive off when it is safe to do so.
iThe current transmission positionP, R, N,
orD appears in the multifunction display
(
page 195).
Warning!G
It is dangerous to shift the automatic trans-
mission out of park positionP or neutral
positionN 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.
iThe gear selector lever returns to its original
position.iThe gear selector lever returns to its original

Automatic transmission
Shifting from D or R to N
If you want to select neutral positionN
with the transmission being in drive
positionD or reverse gearR:
With the vehicle at a standstill, depress
the brake pedal and keep it pressed.
Step firmly on parking brake pedal
(
page 68).
Move gear selector lever up to resis-
tance point when in drive positionD or
down to resistance point when in
reverse gearR to select neutral
positionN.
Release the brake pedal.
Shifting procedure
The automatic transmission selects indi-
vidual gears automatically, depending on:

drive positionD (page 195) with gear
ranges (
page 200)

the position of the accelerator pedal
(
page 198)

the vehicle speedWith drive positionD selected, you can use
the steering wheel gearshift control
buttons (
page 201) to influence trans-
mission shifting by:

limiting the gear range

changing gears manually
Transmission positions
The current transmission position appears
in the multifunction display.
1Current transmission position
iWhen the vehicle needs to be moved with
the engine switched off and the transmission set
to neutral positionN (
page 195), do not
depress the parking brake pedal.!Allow engine to warm up under low load use.
Do not place full load on the engine until the
operating temperature has been reached.
Shift into reverse gearR or park positionP only
when the vehicle is stopped.
Avoid spinning of a drive wheel for an extended
period when driving off on slippery road
surfaces. This may cause serious damage to the
drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
!If the current transmission position does not
appear in the multifunction display due to a
malfunction, for example, make sure that the
automatic transmission is in the desired position
by carefully driving off with the transmission in
drive positionD.
Do not limit the gear range.

Automatic transmission
Towing a trailer
If you tow a trailer, note the following
points:

Manually shift to a lower gear range
(
page 200) if the transmission hunts
between gears on inclines.
A lower gear range and reduction of
speed reduces the chance to overload
or overheat the engine.
For more information on trailer towing, see
the “Operation” section (
page 366).
Gear ranges
With the automatic transmission in drive
positionD, you can select a gear range for
the automatic transmission to operate
within.
You can limit the gear range by pressing
the left gearshift button on the steering
wheel gearshift control, and reverse the
gear range limit by pressing the right gear-
shift button on the steering wheel gearshift
control (
page 201).The selected gear range appears in the
multifunction display.
1Current gear range
Effect
ïThe transmission shifts through
sixth gear only.
îThe transmission shifts through
fifth gear only.
éThe transmission shifts through
fourth gear only.
èThe transmission shifts through
third gear only.
With this selection you can use
the braking effect of the engine.
Effect
çThe transmission shifts through
second gear only.
Allows the use of engine’s
braking power when driving:

on steep downgrades

in mountainous regions

under extreme operating
conditions
æThe transmission operates in
first gear only.
For maximum use of engine’s
braking effect on very steep or
lengthy downgrades.

Upshifting
Briefly press right shift button2.
The transmission will shift to the next
higher gear as permitted by the shift
program. This action simultaneously
extends the gear range of the automat-
ic transmission (
page 200).
Canceling gear range limit
Press and hold right shift button2
until the cipher for the current gear
range disappears from the multifunc-
tion display (
page 200).
The transmission will shift from the
current gear range directly to gear
rangeD.Shifting into optimal gear range
Press and hold left shift button1.
The transmission will automatically
select the gear range suited for optimal
acceleration and deceleration. This will
involve shifting down one or more
gears.Emergency operation (Limp-Home Mode)
If vehicle acceleration becomes less re-
sponsive or sluggish or the transmission
no longer shifts, the transmission is most
likely operating in limp-home (emergency
operation) mode. In this mode only second
gear and reverse gear can be activated.
Stop the vehicle in a safe location.
Shift to park positionP.
Turn off the engine.
Wait at least 10 seconds before
restarting.
Restart the engine.
Shift to drive positionD (for second
gear) or reverse gearR.
Have the transmission checked at an
authorized Mercedes-Benz Light Truck
Center as soon as possible.
iIf you press on the accelerator when the
engine has reached its rpm limit, the transmis-
sion will upshift beyond any gear range limit
selected.

mode. A chime sounds and the LOW
RANGE display3 appears in the multi-
function display.
The indicator lamp2 on the
LOW RANGE switch comes on continu-
ously, indicating that the LOW RANGE
mode has been activated.
Warning!G
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 proce-
dure do not:

switch off the engine

shift the automatic transmission into
another gear
If you do not wait until the shifting proce-
dure has been entirely completed then it
might not be correctly performed. The trans-
fer case might be in neutral, thus interrupt-
ing 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 uninten-
tionally 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 (
page 493).
!The shift procedure can only be performed
when the following conditions are met:

The engine is running (page 41).

The automatic transmission is in positionN
(

The vehicle speed does not exceed 25 mph
(40 km/h).
iThere is no reset to HIGH after the ignition
