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.

starting attempts. Otherwise, non-combusted fuel may 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 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:

12 V.  Jump-starting may only be performed from batteries with a nominal voltage of 12 V.
terminal clamps.  Only use jumper cables which have a sufficient cross-section and insulated terminal clamps.
the pulley  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.
jump-start connected  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.

information about jump-starting can be obtained from any Jumper cables and further information about jump-starting can be obtained from any authorized Mercedes-Benz Center, for example.
