Warning!
G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause uncon-
sciousness and lead to 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 win-
dow fully open.
!Do not depress the accelerator.

Starting difficulties
If the engine does not start as described,
carry out the following steps:
Turn key in starter to position0 and re-
peat starting procedure.
Remember that extended starting at-
tempts can drain the battery.

Get a jump start (
page 264).
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

113 Controls in detail
Automatic transmission
Automatic transmission
Information for driving with an automatic
transmission is found in the “Getting start-
ed” section (
page 44).
Your transmission adapts its gear shifting
process to your individual driving style by
continually adjusting the shift points up or
down. These shift point adjustments are
performed based on current operating 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 selector lever positionD with gear
ranges4, 3, 2, 1


the position of the accelerator pedal
(page 117)


the vehicle speedWhen the selector lever is in positionD,
you can influence transmission shifting by


limiting the gear range


changing gears yourself
One-touch gearshifting
Even with an automatic transmission you
can change the gears yourself when the
selector lever is in positionD.
Downshifting
Briefly press the selector lever to the
left in the D–direction.
The transmission will shift from the cur-
rent gear to the next lower gear. This
action simultaneously limits the gear
range of the transmission
(page 114).
Warning!
G
It is dangerous to shift the 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 en-
gine is idling normally and when your right
foot is firmly on the brake pedal.
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.

114 Controls in detailAutomatic transmissionUpshifting
Briefly press the selector lever to the
right in the D+direction.
The transmission will shift from the cur-
r e n t g e a r t o t h e n e x t h i g h e r g e a r a s p e r -
mitted by the shift program. This action
simultaneously extends the gear range
of the transmission.Canceling gear range limit

Press and hold the selector lever in the
D+direction until D reappears in the
tachometer display field.
Shifting into optimal gear range

Press and hold the gear selector lever
in the D– direction.
The transmission will automatically se-
lect the gear range suited for optimal
acceleration and deceleration. This will
involve shifting down one or more
gears.
Gear ranges
With the selector lever in positionD, you
can limit the transmission’s gear range by
pressing the lever to the left (D-), and re-
verse the gear range limit by pressing the
lever to the right (D+).
The selected gear range will appear in the
tachometer display field. If you press on
the accelerator when the engine has
reached its rpm limit, the transmission will
upshift beyond any gear range limit
selected.
iTo avoid overrevving the engine when
the selector lever is moved to the D– di-
rection, the transmission will not shift
to a lower gear if the engine’s max.
speed would be exceeded.

117 Controls in detail
Automatic 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.

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

Manually shift to a lower gear range
(4,3, 2, 1), if the transmission hunts
between gears on inclines
(page 114).
A lower gear range and reduction of
speed reduces the change to overload
or overheat the engine.


At very steep inclines switch transfer
case to LOW RANGE mode
(page 118).
For more information on trailer towing, see
the “Operation” section (
page 192).Emergency operation (Limp Home
Mode)
If the vehicle acceleration worsens or the
transmission no longer shifts, the trans-
mission is most likely operating in limp
home mode. In this mode only 2nd gear
and reverse gear can be activated.
Stop the vehicle.

Move selector lever to positionP.

Turn off the engine.

Wait at least ten seconds before re-
starting.

Move selector lever to position D (for
2nd gear) or R.

Have the transmission checked at an
authorized Mercedes-Benz Light Truck
Center as soon as possible.

control may not be able to maintain the
set speed. Once the grade eases, the
set speed will be resumed.
!Moving gear selector lever to
positionN while driving also cancels
cruise control. However, the gear se-
lector lever should not be moved to
positionN while driving except to coast
when the vehicle is in danger of skid-
ding (e.g. on icy roads).iThe last stored speed is canceled when
you turn off the engine.

Transmission in LOW RANGE mode
Warning!
G
The speed stored in memory should only be
set again if prevailing road conditions per-
mit. Possible acceleration or deceleration
differences arising from returning to preset
speed could cause an accident and/or seri-
ous injury to you and others.
iDepressing the accelerator pedal does
not deactivate the cruise control. After
brief acceleration (e.g. for passing),
cruise control will resume the last
speed set.
iWhen you use the cruise control lever
to decelerate, the transmission will au-
tomatically downshift if the engine’s
braking power does not brake the vehi-
cle sufficiently.iThe cruise control should not be used
during off-road driving.

188 OperationDriving instructions

Switch to LOW RANGE mode before
starting to drive up or down steep in-
clines (
page 118).


Driving on embankments, slopes and
other steep inclines should only be
done straight up or downhill, i.e. in the
line of gravity. Maximum vehicle climb-
ing ability is a 60% grade.


Do not drive along the side of a slope
(danger of vehicle rollover). If in doing
so, the vehicle begins to show a ten-
dency to roll, immediately steer into a
line of gravity (straight up or downhill).


To help avoid the vehicle rolling over,
never turn it around on steep inclines.
If the vehicle cannot complete the at-
tempted climb, back it down in reverse
gear.


Utilize the engine’s braking power
when descending a slope, observe the
engine speed (do not overrev the en-
gine). Apply the service brake as need-
ed.


Check the brakes after a lengthy down-
grade drive.
Traction in steep terrain


Be easy on the accelerator and watch
for continuous wheel traction when
driving in steep terrain.
The 4-ETS helps greatly when starting
out on a steep incline when the front
wheels have then the tendency to slip
due to the weight shifting away the
front axle.
The 4-ETS recognizes the situation and
limits the torque for the front wheels by
braking them. Simultaneously the
torque for the rear wheels is increased.Driving across a hilltop


Decelerate just ahead of a hilltop (do
not select gear rangeN), to prevent the
vehicle from speeding up too much af-
ter climbing a hill.
Use the momentum of the vehicle to
drive across the hilltop.
Driving in this manner prevents the ve-
hicle from jumping across the hilltop
and thus loosing its forward momen-
tum.
iAvoid excessive engine speeds – drive
with moderate engine speeds
(max. 3000 RPM).
Select gear range2 or1 on the auto-
matic transmission (
page 114).

294 Technical termsEngine oil viscosity
Measurement for the inner friction (vis-
cosity) of the oil at different tempera-
tures. The higher the temperature an
oil can tolerate without becoming thin,
or the lower the temperature it can tol-
erate without becoming viscous, the
better the viscosity.
