5. Start engine of the vehicle with the charged battery
and run at high idle. Make sure the cables are not
on or near pulleys, fans, or other parts that move
when the engine is started. Allow the discharged
battery to charge for a few minutes. Start engine of
the disabled vehicle in the usual manner.
6. After the engine has started, remove jumper cables
by exactly reversing the above installation
sequence, starting with the last connection made
first. When removing each clamp, make sure that it
does not touch any other metal while the other end
is still attached to a battery.
Notes:
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 catalytic converter.Tow i n g t h e v e h i c l e
Mercedes-Benz recommends that the vehicle be
transported with all wheels off the ground using flatbed
or appropriate wheel lift/ dolly equipment. This method
is preferable to other types of towing.
Caution!
Use flatbed or wheel lift/ dolly equipment with key in
steering lock turned to position 0.
Do not tow with sling- type equipment. Towing with
sling- type equipment over bumpy roads will damage
radiator and supports.
To prevent damage during transport, do not tie down
vehicle by its chassis or suspension parts.
Switch off the tow-away alarm (see page 40) as well as
the ESP (see page 218).
When circumstances do not permit the recommended
towing methods, the vehicle may be towed with all
wheels on the ground or front wheels raised only so far
as necessary to have the vehicle moved to a safe location
where the recommended towing methods can be
employed.
