To calibrate the compass:
If the vehicle was exposed to a significant magnetic
zone, such as high voltage power lines, the compass
may have to be calibrated.
Calibration of the compass should be done in an area
free of steel superstructures and power lines. All
electrical consumers (e.g. exterior lamps, climate
control, etc.) should be switched off, doors and liftgate
closed. Do not open or close the roof. An open door or
liftgate triggers the display “–––”.
1. Start and run the engine.
2. Press MODE key repeatedly until the compass
display appears in the trip computer display.
3. Press RESET key to select the compass zone display.
4. Press RESET repeatedly until the correct zone, as
determined from the zone map (see page 85), is
shown in the display.
5. Press MODE key, “CAL–” appears in the display.
6. Press and hold RESET for a minimum of 2 seconds.7. Without interruption drive two or more full circles
at a speed between 3 mph (5 km / h) and 7 mph
(10 km / h) during which the message “CAL” is
replaced with a compass bearing (e.g. N, SW etc.),
immediately followed by three full circles at the
same speed, with only the rear window defroster
switched on. The defroster can be switched off
again. The calibration of the compass is now
complete.

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
client 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.

Starting and turning off the engine
Before starting
Ensure that parking brake is engaged and that selector
lever is in position “P” or “N”. Turn key in steering lock
to position 2. The charge indicator lamp should come on.
Starting
Do not depress accelerator.
Briefly turn key in steering lock clockwise to the stop
and release. The starter will engage until the engine is
running.
If engine will not run, and the starting procedure stops,
turn key completely to the left and repeat starting the
engine.
After several unsuccessful attempts, have the system
checked at the nearest authorized Mercedes-Benz Light
Truck Center.
A starting procedure can be interrupted by turning the
key to steering lock position 0.Important!
Due to the installed starter non-repeat feature, the key
must be turned completely to the left before attempting
to start the engine again.
In areas where temperatures frequently drop below -4°F
(-20°C) we recommend that an engine block heater be
installed. Your authorized Mercedes-Benz Light Truck
Center will advise you on this subject.
Note:
In case the engine cannot be started and the
messagesÁ and î are shown in the odometer
display field, the system is not operational. Contact an
authorized Mercedes-Benz Light Truck Center or call
1-800-FOR-MERCedes (in the USA), or 1-800-387-0100
(in Canada).
Turning off
Turn the key in the steering lock to position 0 to stop the
engine.
The key can only be removed with the selector lever in
position “P”.

166 Automatic transmission
Te ch n ica l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index
Driving
The selector lever is automatically locked while in
position “P”. To move the selector lever out of
position “P”, the service brake pedal must be firmly
depressed before the shift lock will release.
Shift selector lever to the desired position only when the
engine is idling normally and the service brake is
applied. Do not release the brake until ready to drive.
The vehicle may otherwise start creeping when the
selector lever is in drive or reverse position.Important!
After selecting any driving position from “N” or “P”,
wait a moment to allow the gear to fully engage before
accelerating, especially when the engine is cold.
Accelerator position
Partial throttle = early upshifting = normal acceleration
Full throttle = later upshifting = rapid acceleration
Kickdown (depressing the accelerator beyond full
throttle) = downshifting to a lower gear = maximum
acceleration. Once the desired speed is attained, ease up
on the accelerator – the transmission shifts up again.
Stopping
For brief stops, e.g. at traffic lights, leave the
transmission in gear and hold vehicle with the service
brake.
For longer stops with the engine idling, shift into “N”
or “P” and hold the vehicle with the service brake.
When stopping the vehicle on an uphill gradient, do not
hold it with the accelerator, use the brake. This avoids
unnecessary transmission heat build up.
Wa r n i n g !
It is dangerous to shift the selector lever out of “P”
or “N” 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.

120 in (50 cm)
Before driving through water, determine its depth. It
should not be deeper than approximately
20 inches (50 cm).Switch to LOW RANGE mode before driving through
water.
Switch off the exterior lamps as well as the climate
control.
Enter the water only at a shallow spot. Never take a
running start. Drive slowly, avoiding a bow wave.
Do not stop vehicle immersed in water, and do not shut
off the engine.
To dry the brakes, apply pressure to the brake pedal
several times after leaving the water.

Tow in g a t r ai le r
There are many different laws, including speed limit
restrictions, having to do with trailer towing. Make sure
t ha t your rig will be lega l, not only for w here 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.

Low engine oil level warning lamp
With the key in steering lock position 2, the
oil level warning lamp comes on and should
go out when the engine is running.
If the warning lamp does not go out after starting the
engine, or comes on with the engine running and at
operating temperature, the engine oil level has dropped
to approximately the minimum mark on the dipstick.
When this occurs, the warning lamp will first come on
intermittently and then stay on if the oil level drops
further.
If no oil leaks are noted, continue to drive to the nearest
service station where the engine oil should be topped to
the “full” mark on the dipstick with an approved oil.
The low engine oil level warning light should not be
ignored. Extended driving with the light illuminated
could result in serious engine damage that is not
covered by the Mercedes-Benz Limited Warranty.
In addition to the warning lamp, the engine oil level
should be periodically checked with the dipstick or via
the oil level indicator in the odometer display field, for
example during a fuel stop, or before a long trip (see
engine oil level indicator on page 89 and checking
engine oil on page 233).Low engine coolant level warning
When the coolant level warning lamp comes
on while driving, then the coolant level has
dropped below the required level, or the
coolant temperature is in the red zone. If no leaks are
noticeable and the engine temperature does not
increase, continue to drive to the nearest service station
and have coolant added to the coolant system, see
page 234. If the engine temperature reaches the red
zone, move vehicle to an area which is in a safe distance
from the roadway and turn off the engine. Also see
coolant temperature gauge on page 81.
The low engine coolant level warning should not be
ignored. Extended driving with the symbol displayed
may cause serious engine damage not covered by the
Mercedes-Benz Limited Warranty.
In cases of major or frequent minor coolant loss, have
the cooling system checked at your authorized
Mercedes-Benz Light Truck Center as soon as possible.
Notes:
Do not drive without coolant in the cooling system. The
engine will overheat causing major engine damage.
Monitor the coolant temperature gauge while driving.
