Therefore, we strongly recommend that you have the
battery charge checked frequently, and corrected if
necessary, especially if you use the vehicle less than
approximately 200 miles (300 km) per month,
mostly for short distance trips, or if it is not used for
long periods of time.
Only charge a battery with a battery charger after the
battery has been disconnected from the vehicle’s
electrical circuit.
Always disconnect the battery negative lead first and
connect last.
When removing and connecting the battery, always
make sure that all electrical consumers are off and the
key is in steering lock position 0. The battery must
always be securely installed when the vehicle is in
operation. During removal and installation always
protect the disconnected battery positive (+) terminal
with the cover attached to the battery.
While the engine is running the battery terminal clamps
must not be loosened or detached, otherwise the
generator and other electronic components would be
damaged.Note:
The gear selector lever will remain locked in
position “P” and the electronic key cannot be turned in
the steering lock if the vehicle battery is disconnected
or discharged.
After reconnecting the battery also set the clock in
instrument cluster (see page 87), set date in trip
computer (see page 89), resynchronize the sliding / pop-
up roof (see page 294) and the electronic stability
program (ESP) (see page 224).
Battery recycling
Batteries contain material that can harm the
environment with improper disposal.
Large 12 Volt storage batteries contain lead.
Recycling of batteries is the preferred method of
disposal.
Many states require sellers of batteries to accept old
batteries for recycling.

276 Jump starting

The battery is located on the right side in the engine
compartment.
Proceed as follows:
1. Position the vehicle with the charged battery so that
the jumper cables will reach, but never let the
vehicles touch. Make sure the jumper cables do not
have loose or missing insulation.
2. On both vehicles:
•Turn off engine and all lights and accessories,
except hazard warning flashers or work lights.
•Apply parking brake and shift selector lever to
position “P”.
Important!
3. Clamp one end of the first jumper cable to the
positive (+) under hood terminal of the discharged
battery and the other end to the positive (+) terminal
of the charged battery. Make sure the cable clamps
do not touch any other metal parts.
4. Clamp one end of the second jumper cable to the
grounded negative (–) terminal of the charged
battery and the final connection to the negative (–)
terminal of the discharged battery.Important!
5. Start engine of the vehicle with the charged battery
and run at high idle. Make sure the cables are not
on or near pulleys, fans, or other parts that move
when the engine is started. Allow the discharged
battery to charge for a few minutes. Start engine of
the disabled vehicle in the usual manner.
6. After the engine has started, remove jumper cables
by exactly reversing the above installation
sequence, starting with the last connection made
first. When removing each clamp, make sure that it
does not touch any other metal while the other end
is still attached.
Notes:
If engine does not run after several unsuccessful
starting attempts, have it checked at the nearest
authorized Mercedes-Benz Light Truck Center.
Excessive unburned fuel may damage the catalytic
converter.

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
data Instruments
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.

Use a gentle dishwashing detergent or mild detergent
for delicate fabrics as a washing solution. Wipe with a
cloth moistened in lukewarm solution. Do not use
scouring agents.
Steering wheel and gear selector lever
Wipe with a damp cloth and dry thoroughly or clean
with Mercedes-Benz approved Leather Care.Cup holder
