40 Getting started
Unlocking
For information on starting the engine, see
(
page 54).
iWhen you switch on the ignition, the indica-
tor and warning lamps (except high beam head-
lamp indicator lamp and turn signal indicator
lamps unless activated) in the instrument cluster
come on. The indicator and warning lamps
(except high beam headlamp indicator lamp and
turn signal indicator lamps if activated) will go
out when the engine is running. This indicates
that the respective systems are operational.
iThe SmartKey can only be removed from the
starter switch with the gear selector lever in park
position P.
iIf the SmartKey is left in starter switch
position 0 for an extended period of time, it can
no longer be turned in the switch. In this case,
the steering is locked. To unlock, remove
SmartKey from the starter switch and reinsert.
!If the SmartKey cannot be turned in the
starter switch, the battery may not be
sufficiently charged.

Check the battery and charge it if necessary
(
page 396).

Get a jump start (page 397).
To prevent accelerated vehicle battery discharge
or a completely discharged vehicle battery,
always remove the SmartKey from the starter
switch when the engine is not in operation.

394 Practical hints
Battery
The battery is located in front of the rear
seat bench and below the cup holder.
Jump starting terminals are located on the
driver’s side of the engine compartment
(
page 398).
The battery should always be sufficiently
charged in order to achieve its rated
service life. Refer to Maintenance Booklet
for battery maintenance intervals.
If you use your vehicle mostly for
short-distance trips, you will need to have
the battery charge checked more
frequently.
When replacing the battery, always use
batteries 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.
Large 12-volt storag
e batteries contain
lead. Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.
iMercedes-Benz recommends to have the
battery replaced at an authorized
Mercedes-Benz Light Truck Center.
Warning!G
Observe all safety instructions and precau-
tions when handling automotive batteries.
Risk of explosion.
Fire, open flames and smoking
are prohibited when handling
batteries. Avoid creating sparks.
Battery acid is caustic. Do not
allow it to come into contact

Never lean over batteries while connecting,
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 pr oduce hydrogen gas,
which is flammable and explosive. Keep

improper connection of jumper cables,
smoking, etc.
Warning!G
Jump starting must only be done using the
jump-start terminals located in the engine
compartment (
page 398).
Warning!G
Do not place metal objects on the battery as
this could result in a short circuit.
Use leak-proof battery only to avoid the risk

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, contac t 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 disc harged, the battery can
be charged using the jump-start terminals
located in the engine compartment
(
page 398).
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 th e 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 ch arge unit* specially
adapted for Mercedes-Benz vehicles and
tested and approved by Mercedes-Benz is
available, permitting the charging of the
battery in its installe d position. Contact an
authorized Mercedes-Benz Light Truck
Center for information and availability.

Practical hints
Jump starting
 Jump starting
If the battery is disc harged, 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 398).

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 thes e directions will cause
damage to the electr onic 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 pr oduce 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 explod ing, 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.
