Practical hints
Jump starting
Jump starting
If the battery is discharged, the engine can 
be started with jumper cables and the 
battery of another vehicle. Observe the 
following:
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 use a12-volt battery to jump start 
your vehicle. Jump starting with a high-
er voltage battery could damage the ve-
hicle’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 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.
!
Vehicles with automatic transmission* 
and/or 4MATIC: 
Do not tow-start the vehicle.
!
Avoid repeated and lengthy starting 
attempts.
Do not attempt to start the engine using a bat-
tery quick charge unit.
If engine does not run after several unsuccessful 
starting attempts, have it checked at the nearest 
authorized Mercedes-Benz Center.
Excessive unburned fuel generated by repeated 
failed starting attempts may damage the catalyt-
ic 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 at-
tached to a battery.
Warning!
