Mounting The Spare Wheel - Mercedes-Benz 2008 M-Class Operator's Manual

i
Vehicles with collapsible tire (ML 63 AMG
only):
You can use the power outlets, except for the
power outlet in the front center console, to
operate the electric air pump even when the
ignition is switched off, e.g. in order to inflate the
collapsible emergency spare tire ( page 485).
An emergency shut-off feature ensures that the
vehicle's electrical voltage does not fall below a
minimum level. If the voltage drops to this mini-
mum level, the power outlets are automatically
switched off. This ensures that enough power re-
mains to start the engine.

Depending on vehicle production date your

jacking up the vehicle as otherwise the vehicle's
underbody can be damaged. See separate
instructions for scissors-type jack.
Practical hints
Lifting the vehicle
Warning!
When jacking up the vehicle, only use the
jack which has been specifically approved
by Mercedes-Benz for your vehicle.
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. Make
sure the jack arm is fully seated in the jack
take-up bracket.
The jack is intended only for lifting the
vehicle briefly for wheel changes. It is not
suited for performing maintenance work
under the vehicle. To help avoid personal in-
jury, use the jack only to lift the vehicle dur-
ing a wheel change.
Never get beneath the vehicle while it is sup-
ported by the jack. Keep hands and feet
away from the area under the lifted vehicle.
Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.
