Where will I find ...?
Vehicle jackThe vehicle jack is located underneath the
cargo compartment floor.
Storage position
Remove vehicle jack from its storage
compartment (
page 470).
Turn crank handle in the direction of ar-
row as far as it will go.
!
Vehicles with factory-mounted
running-boards*:
Your vehicle is equipped with a scissors-type
jack (located under the cargo compartment
floor) designed for use with factory-mounted
running boards. Only use this jack when jacking
up vehicles with factory-mounted running boards
as otherwise the vehicle’s underbody can be
damaged. See separate instructions for scis-
sors-type jack.
!
To prevent damage, always disengage the
strap of the securing hook and lower the cargo
compartment floor (
page 469) before closing
the tailgate.
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage the parking brake while
the vehicle is raised. Be certain that the jack
is always vertical (plumb line) when in use,
especially on hills. Always try to use the jack
on a level surface.
Make sure that the jack arm is fully seated
in the jack take-up bracket. Always lower
the vehicle onto jackstands of sufficient
capacity before working under the vehicle.

Safe vehicle operation depends on proper
exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp as-
semblies are in good working order at all
times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. See an authorized
Mercedes-Benz Light Truck Center for
headlamp adjustment.
i
If the headlamps or front fog lamps are
fogged up on the inside as a result of high humid-
ity, driving the vehicle a distance with the lights
on should clear up the fogging.

Substitute bulbs will be brought into use
when the following lamps malfunction:
Turn signal lamps
Brake lamps
Parking lamps
Tail lamps
Read and observe the messages in the multi-
function display (
