Jump-starting

G
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 converter and create a risk of fire.
Do not use a rapid charging device to start the vehicle.
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,
X
jump-start the vehicle using a second battery or a jump-starting device.
You may only jump-start the vehicle when the engine and catalytic converter are cold.
X
Do not start the engine if the battery is frozen. Let the battery thaw first.
X
Jump-starting may only be performed from batteries with a nominal voltage of 12 V.
X
Only use jumper cables which have a sufficient cross-section and insulated terminal clamps.
X
Make sure that the jumper cables cannot come into contact with parts, such as the pulley
X
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
X
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.
