Important!
If the indicator lamps do not start flashing after
pressing one of the buttons or remain illuminated (in
red) at any time, the Tele Aid system has detected a fault
or the service is not currently active, and may not
initiate a call. Visit your Mercedes-Benz Light Truck
Center and have the system checked or contact the
Response Center at 1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada) as soon as possible.Upgrade Signals
Tele Aid system processes calls using the following
priority.
•Automatic emergency – First priority
•Manual emergency – Second priority
•Roadside assistance – Third priority
•Information – Fourth priority
Should a higher priority call be initiated while you are
connected, an upgrade (alternating) tone will be heard,
and the appropriate indicator lamp will flash. If certain
information such as vehicle identification number or
customer information is not available, the operator may
need to retransmit. During this time you will hear a
chirp and voice contact will be interrupted. Voice
contact will resume once the retransmission is
completed. Once a call is concluded, a chirp will be
heard and the appropriate indicator lamp will stop
flashing. The MCS system operation will resume.

Te ch n i c a l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index Maneuvering
To maneuver in tight areas, e.g. when pulling into a
parking space, control the vehicle speed by gradually
releasing the brakes. Accelerate gently and never
abruptly step on the accelerator.
To rock a vehicle out of soft ground (mud or snow),
alternately shift from forward to reverse, while applying
slight partial throttle.
Rocking a vehicle free in this manner may cause the
ABS or traction system malfunction indicator lamp to
come on. Turn off and restart the engine to clear the
malfunction indication.Towing a trailer
If the transmission hunts between gears on inclines,
manually shift to a lower gear (select “4”, “3”, “2”
or “1”). A lower gear and reduction of speed reduces the
chance of engine overloading and / or overheating.
At very steep inclines, not manageable with selector
lever in position “1”, switch transfer case to LOW
RANGE, see page 227 for instructions on how to engage
LOW RANGE.
For instructions on trailer towing refer to page 209.
Wa r n i n g !
Getting out of your vehicle with the selector lever
not fully engaged in position “P” is dangerous.
Also, when parked on an incline, position “P” alone
may not prevent your vehicle from moving,
possibly hitting people or objects.Always set the parking brake in addition to shifting
to position “P”, see page 191 for parking brake. When parked on an incline, also turn front wheel
against curb.
Wa r n i n g !
When leaving the vehicle always remove the key
from the steering lock, and lock the vehicle. Do not
leave children unattended in the vehicle, or with
access to an unlocked vehicle. Children could move
the gear selector lever from position “P”, which
could result in an accident or serious injury.

Selector lever position
The current selector lever position is indicated in the
gear range indicator display. The automatic gear
shifting process can be adapted to specific operating
conditions using the selector lever.Park position
The park position is to be used when parking the
vehicle. Engage only with the vehicle stopped.
The park position is not intended to serve as a
brake when the vehicle is parked. Rather, the
driver should always use the parking brake in
addition to placing the selector lever in park to
secure the vehicle.
Notes:
The key can only be removed from the steering
lock with the selector lever in position “P”. With
the key removed, the selector lever is locked in
position “P”.
With a malfunction in the vehicle’s electrical
system the selector lever could remain locked in
position “P”. To unlock the selector lever
manually, see page 281.
Reverse gear
Shift to reverse gear only with the vehicle
stopped.

212 Driving instructions

Towing a trailer
There are many different laws, including speed limit
restrictions, having to do with trailer towing. Make sure
that your rig will be legal, not only for where you reside,
but also for where you will be driving. A good source for
this information can be the police or local authorities.
Before you start driving with the trailer, check the
trailer hitch, break-away switch, safety chains, electrical
connections, lighting and tires. Also adjust the mirrors
to permit unobstructed view beyond rear of trailer.
If the trailer has electric brakes, start your vehicle and
trailer moving slowly, and then apply only the trailer
brake controller by hand to be sure the brakes are
working properly.
When towing a trailer, check occasionally to be sure that
the load is secure, and that lighting and trailer brakes
(if so equipped) are functioning properly.
Always secure items in the trailer to prevent load shifts
while driving.
Take into consideration that when towing a trailer, the
handling characteristics are different and less stable
from those when operating the vehicle without a trailer.
It is important to avoid sudden maneuvers.The vehicle and trailer combination is heavier, and
therefore is limited in acceleration and climbing ability,
and requires longer stopping distances. It is more prone
to reacting to side wind gusts, and requires more
sensitive steering input.
In order to gain skill and an understanding of the
vehicle’s behavior, you should practice turning,
stopping and backing up in an area which is free from
traffic.
If possible, do not brake abruptly, but rather engage the
brake slightly at first to permit the trailer to activate its
brake. Then increase the braking force.
Caution!
If the trailer should begin to sway, reduce the vehicle’s
speed and use the brake controller by hand to straighten
out the vehicle and trailer. In no case should you
attempt to straighten out the tow vehicle and trailer by
increasing the speed or oversteering and stepping on
the brakes.
If the transmission hunts between gears on inclines,
manually shift to a lower gear (select “4”, “3”, “2”
or “1”). A lower gear and reduction of speed reduces the
chance of engine overloading and / or overheating.

The rear towing eye is located behind the right side
cover (1) in the bumper panel.
3Cover
4Tow i n g eye , r e a rCover removal:
Grip cover at bottom and securely pull out.
Cover installation:
Engage cover and press in securely.
We recommend that the vehicle be transported using
flat bed equipment. This method is preferable to other
types of towing.
The vehicle may be towed with all wheels on the ground
and the selector lever in position “N” for distances up to
30 miles (50 km) and at a speed not to exceed 30 mph
(50 km / h). The key must be in steering lock position 2.
Note:
The steering lock cannot be locked or unlocked and the
selector lever remains in position “P” if the battery is
disconnected or discharged (see page 273). See
page 281 for transmission selector lever, manually
unlocking.
Wa r n i n g !
In order to avoid possible serious burns or injury,
use extreme caution when removing the cover,
because the rear exhaust pipe is extremely hot.

281 Towing
Te ch n i c a l

and controlsOperation DrivingInstrument
cluster displayPractical hintsCar care Index Transmission selector lever, manually unlocking
In the case of power failure the transmission selector
lever can be manually unlocked, e.g. to tow the vehicle.
To do so, insert a pin (1), e.g. ball point pen, into the
covered opening below the position “D” of the shift
pattern. While pushing the pin down, move selector
lever from position “P”.
After removal of the pin from the opening, the cover will
not close fully. Only after moving the selector lever to
position “D–” does the cover return to its closed
position.Stranded vehicle
Freeing a stranded vehicle, on which the wheels are dug
into sand or mud, should be done with the greatest of
care, especially if the vehicle is heavily loaded.
Avoid pulling the vehicle jerkily or diagonally, since it
could result in damage to the chassis alignment.
Never try to free a vehicle that is still coupled to a
trailer.
If possible, a vehicle equipped with trailer hitch receiver
should be pulled backward in its own previously made
tracks.
