Battery
Battery
The battery is located in front of the rear
seat bench and below the cup holder. Jump
starting terminals are located in the left
side of the engine compartment
(
page 357). Refer to Maintenance
Booklet for battery maintenance intervals.
The battery should always be sufficiently
charged in order to achieve its rated ser-
vice life.
If you use your vehicle less than approxi-
mately 200 miles (300 km) per month,
mostly for short-distance trips, or if it is not
used for long periods of time, you will need
to have the battery charge checked more
frequently and corrected if necessary.
When replacing batteries, always use bat-
teries approved by Mercedes-Benz.
If you do not intend to operate your vehicle
for an extended period of time, consult an
authorized Mercedes-Benz Light Truck
Center about steps you need to observe.Batteries contain materials that can harm
the environment if disposed of improperly.
Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.
For more information, see “Battery”
(
page 353).
G
Observe all safety instructions
and precautions when handling
automotive batteries.
A
Risk of explosion
D
Keep flames or sparks away
from battery. Do not smoke.
B

#BATTERY/ALTERNATOR
VISIT WORKSHOP!The battery was charged with a battery
charger or jump started.Have the battery checked at a service
station.
The battery is no longer charging.
Possible causes:

alternator malfunctioning

broken poly-V-belt
Stop immediately and check the
poly-V-belt.
If it is broken:
Do not continue to drive. Otherwise
the engine will overheat due to an in-
operative water pump which may re-
sult in serious engine damage not
covered by the Mercedes-Benz Limited
Warranty. Notify an authorized
Mercedes-Benz Light Truck Center.
If it is intact:
Turn off unnecessary electric consum-
ers.
Drive immediately to the nearest
authorized Mercedes-Benz Light Truck
Center.
UNDERVOLTAGE
ENGINE ON!The battery has insufficient voltage.Start the engine.

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

Jump starting should only be performed
when the engine and catalytic convert-
er are cold.

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

Only use 12 volt battery to jump start
your vehicle. Jump starting with a more
powerful battery could damage the ve-
hicle’s electrical system, which will not
be covered by the Mercedes-Benz
Limited Warranty.

Use only 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.
!
Avoid repeated and lengthy starting at-
tempts.
Do not attempt to start the engine us-
ing a battery quick charge unit.
If engine does not run after several un-
successful 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 and
may present a fire risk.
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.
!
Do not tow-start the vehicle.
