Battery
Disconnecting, removing, reinstalling
and reconnecting the battery
Disconnecting, removing, reinstalling and
reconnecting the battery is a complicated
and technically demanding procedure that
also requires safety precautions to avoid
the risk of injury. We strongly recommend
that it should be performed by a qualified
technician only. If it is necessary to work
on the battery, contact a local authorized
Mercedes-Benz Light Truck Center or call
our Customer Assistance Center at
1-800-FOR-MERCedes (1-800-367-6372).
Charging the battery
If the battery is discharged, the battery can
be charged using the jump-start terminals
located in the engine compartment
(
page 400).
Charge the battery in accordance with
the instructions of the battery charger
manufacturer.
!Never invert the terminal connections!
!The battery, its filler caps and the vent tube
must always be securely installed when the
vehicle is in operation.
Warning!G
Never charge a battery while still installed in
the vehicle unless the accessory battery
charge unit* approved by Mercedes-Benz is
being used. Gases may escape during charg-
ing and cause explosions that may result in
paint damage, corrosion or personal injury.
An accessory battery charge unit* specially
adapted for Mercedes-Benz vehicles and
tested and approved by Mercedes-Benz is
available, permitting the charging of the
battery in its installed position. Contact an
authorized Mercedes-Benz Light Truck
Center for information and availability.
Charge battery in accordance with the sepa-
rate instructions for the accessory battery
charger*.
iWith a discharged battery

you will no longer be able to turn the
SmartKey in the starter switch

the gear selector lever will remain locked in
park positionP

399 Practical hints
Jump starting
Jump starting
If the battery is discharged, the engine can
be started with jumper cables and the
battery of another vehicle. Observe the
following:

Jump starting should only be performed
using the jump-start terminals located
in the engine compartment
(
page 400).

Jump starting should only be performed
when the engine and catalytic
converter are cold.

Do not start the engine if the battery is
frozen. Let the battery thaw out first.

Only jump start from batteries with the
same voltage rating (12 V). Jump start-
ing with a higher voltage battery could
damage the vehicle’s electrical system,
which will not be covered by the
Mercedes-Benz Limited Warranty.

Only use jumper cables with sufficient
cross-section and insulated terminal
clamps.

Always make sure the jumper cables
are not on or near pulleys, fans, or
other parts that move when an engine
is started or running.
Warning!G
Failure to follow these directions will cause
damage to the electronic components, and
can lead to a battery explosion and severe
injury or death.
Never lean over batteries while connecting
or jump starting, you might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water, and seek
medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and very explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking, etc.
Attempting to jump start a frozen battery
can result in it exploding, causing personal
injury.
Read all instructions before proceeding.
!Do not tow-start the vehicle.
!Avoid repeated and lengthy starting
attempts.
Do not attempt to start the engine using a
battery quick charge unit.
If the engine does not run after several unsuc-
cessful starting attempts, have it checked at the
nearest authorized Mercedes-Benz Light Truck
Center.
Excessive unburned fuel generated by repeated
failed starting attempts may damage the
catalytic converter.
Make sure the jumper cables do not have loose
or missing insulation.
Make sure the cable clamps do not touch any
other metal part while the other end is still
attached to a battery.

400 Practical hints
Jump starting
Make sure the two vehicles do not
touch.
Apply the parking brake (page 62).
Move the gear selector lever to park
positionP.
Turn off all electrical consumers.
Open the hood (page 267).The jump-start terminals are located on
the driver’s side of the engine compart-
ment.
1Cover
2Positive (+) terminal
3Negative (-) terminal Open cover1 of the positive terminal
of both vehicles.
Connect positive terminal2 and the
positive terminal of the charged battery
with the jumper cable. Clamp the cable
to the charged battery first.
Start the engine of the vehicle with the
charged battery and run at idle speed.
Connect negative terminal3 and the
negative terminal of the charged
battery with the jumper cable. Clamp
the cable to the charged battery first.
Start the engine of the disabled
vehicle.
You can now turn on the electrical con-
sumers. Do not switch on the headlamps
under any circumstances.
Remove the jumper cables first from
the negative terminals on each battery
and then from the positive terminals on
each battery.
You can now switch on the headlamps.
Have the battery checked at the
nearest authorized Mercedes-Benz
Light Truck Center.
Warning!G
Keep flames or sparks away from battery.
Do not smoke.
Observe all safety instructions and precau-
tions when handling automotive batteries
(
page 396).
!Never invert the terminal connections!

402 Practical hints
Towing the vehicle
Warning!G
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle. Adapt your driving accordingly.
!Towing of the vehicle should only be done
using the towing eye. Never attach tow cable,
tow rope or tow rod to vehicle chassis, frame or
suspension parts.
iWhen towing the vehicle with all wheels on
the ground, note the following:
With the automatic central locking activated and
the SmartKey in starter switch position2, the
vehicle doors lock if a wheel is turning at vehicle
speeds of approximately 9 mph (15 km/h) or
above.
To prevent the vehicle doors from locking,
deactivate the automatic central locking
(
page 155).
iTo signal turns while being towed with
hazard warning flasher in use, turn the SmartKey
in starter switch to position2 and activate
combination switch for left or right turn signal in
usual manner – only the selected turn signal will
operate.
Upon canceling the turn signal, the hazard
warning flasher will operate again.
iThe gear selector lever will remain locked in
park positionP and the SmartKey will not turn in
the starter switch if the battery is disconnected
or discharged. For more information, see “Bat-
tery” (
page 396) and “Jump starting”
(
page 399).
For information on manually unlocking the gear
selector lever, see (
page 373).
