Practical hints
Jump starting
Jump starting
If the starter battery is discharged, the en-
gine 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 jump start from batteries with the 
same voltage rating (12V). Jump start-
ing with a more powerful 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 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.
!
Do not tow-start the vehicle.
!
Jump starting may only be performed on the 
battery installed in the engine compartment.
Avoid repeated and lengthy starting attempts.
Do not attempt to start the engine using a bat-
tery quick charge unit.
If the engine does not run after several unsuc-
cessful starting attempts, have it checked at the 
nearest authorized Mercedes-Benz Center.
Excessive unburned fuel generated by repeated 
failed starting attempts may damage the 
catalytic 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 
attached to a battery.
