Jump-starting
WARNING
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 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 attempts. Otherwise, non-combusted fuel may damage the catalytic converter38 and create a risk of fire.
Do not use a rapid-charging device to start the engine.
Make sure the jumper cables are not damaged.
Make sure the jumper cables are not touching any other metal objects when they are connected to the battery.
If your vehicle's battery is discharged, the engine can be jump-started from another vehicle or from a second battery using jumper cables.
Observe the following points:
► The battery is not accessible in all
vehicles. If the other vehicle's battery is not accessible,
jump-start the vehicle using a second battery or a jump-starting device.
► Only jump-start the vehicle when the
engine is cold and the catalytic converter system has
cooled down.
► Do not start the engine if the battery is
frozen. Let the battery thaw first.
► Jump-starting may only be performed from
batteries with a nominal voltage of 12 V.
► Only use jumper cables which have a
sufficient cross-section and insulated terminal clamps.
► Make sure that the jumper cables cannot
come into contact with parts, such as the pulley
or the fan. These parts move when the engine is started and while it is
running.
► If the battery is fully discharged, leave
the battery that is being used to jump-start connected
for a few minutes before attempting to start. This charges the empty battery a
little.
Jumper cables and further information about jump-starting can be obtained from any authorized Mercedes-Benz Center, for example.
► Make sure that the two vehicles do not
touch.
► Apply the parking brake firmly.
► Shift the transmission to position P.
► Switch off all electrical consumers (e.g.
radio, blower, etc.).
► Open the hood.
Position number 7 identifies the charged battery of the other vehicle or an equivalent jumpstarting device.
► Lift up cover 1 of positive terminal 2
in the direction of the arrow.
► Connect positive terminal 2 on your
vehicle to positive terminal 3 of donor battery 7 using the jumper cable,
beginning with your own battery.
► Start the engine of the donor vehicle and
run it at idling speed.
► Remove cover 5 from earth point 6.
► Connect negative terminal 4 of donor
battery 7 to earth point 6 of your vehicle using
the jumper cable, connecting the jumper cable to donor battery 7 first.
► Start the engine.
► Allow the engine to run for a few minutes
before disconnecting the jumper cable.
► First, remove the jumper cable from earth
point 6 and negative terminal 4, then from
positive terminal 2 and positive terminal 3, each time disconnecting from the
contacts
on your own vehicle first.
► Have the battery checked at a qualified
specialist workshop, e.g. an authorized Mercedes-
Benz Center. The jump-starting procedure is not a standard operating state;
therefore, have
the battery checked.
