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.
! Do not tow-start the vehicle. You could
otherwise seriously damage the automatic
transmission which is not covered by the
Mercedes-Benz Limited Warranty.
! Jump starting should only be performed
using the jump-start terminals located in
the engine compartment.
Avoid repeated and lengthy starting
attempts.
Do not attempt to start the engine using a
battery quick-charge unit. If the 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 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.
If the battery is discharged, the engine can be
started with jumper cables and the fully
charged battery of another vehicle or an
equivalent starter pack. Observe the
following:
R Access to the battery is not possible on all
vehicles. If you cannot access the battery
of the other vehicle, provide jump start
power by an external battery or starter
pack.
R Jump starting should only be performed
when the engine and catalytic converter 18
are cold.
R Do not start the engine if the battery is
frozen. Let the battery thaw out first.
R Only jump start from batteries with the
same voltage rating (12 V). Jump starting
with a more powerful battery could damage
the vehicle’s electrical system. Such
damage will not be covered by the
Mercedes-Benz Limited Warranty.
R Only use jumper cables with sufficient
cross-section and insulated terminal
clamps.
R Always make sure the jumper cables are
not on or near pulleys, fans or other parts
