the multifunction display in the instrument cluster (
page 26) for the following:
With the seat unoccupied and the ignition turned on,

the 59indicator lamp on the center console should illuminate and
remain illuminated, indicating that the OCS (
page 79) has deactivated the air
bag.

the message Front Passenger Airbag Enabled See Operator’s Manual or the
message

appear in the multifunction display at any time the seat is unoccupied. Wait at
least 60 seconds for the system to complete the necessary check cycles and to
make sure neither message appears in the multifunction display.
If above conditions are met, you can occupy the front passenger seat again.
Depending on the front passenger classification sensed by the OCS (
page 79),
the59indicator lamp will remain illuminated or go out.
If above conditions are not met, the system is not working properly. Have the system
checked as soon as possible by an authorized Mercedes-Benz Light Truck Center.
Warning!G
If the 59indicator lamp
remains illuminated with an adult occupant
on the front passenger seat even after per-
forming the above corrective steps, do nothave any passenger use the front passenger

Preparing the vehicle
Prepare the vehicle as described
(
page 478).
Vehicles with Minispare wheel:
Take the Minispare wheel out of the
cargo compartment (
page 453).
Take the wheel wrench, the collapsible
wheel chock, and the vehicle jack out
of the cargo compartment
(
page 448).
Vehicles with collapsible tire
(ML 63 AMG only):
Take the collapsible tire, wheel wrench,
wheel bolts, jack, and electric air pump
out of the cargo compartment
(
page 454).Lifting the vehicle
iVehicles 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
vehicle may be equipped with a scissors-type
jack (located under the cargo compartment
floor). If so equipped, only use this jack when
jacking up the vehicle as otherwise the vehicle’s
underbody can be damaged. See separate
instructions for scissors-type jack.
Warning!G
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.
