Bulbs and bulb sockets can be very hot.
Allow the lamp to cool down before chang-
ing a bulb.
Keep bulbs out of reach of children.
Halogen lamps contain pressurized gas.
A bulb can explode if you:

touch or move it when hot


drop the bulb


scratch the bulb
Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the
lamp and its components. We recommend
that you have such work done by a qualified
technician.

284 Practical hintsFlat tireMounting the spare wheel Preparing the vehicle

Park the vehicle as far as possible from
moving traffic on a hard surface.

Turn on the hazard warning flashers.

Engage the steering wheel lock in the
straight ahead position.

Set the parking brake.

Move the gear selector lever toP.

Have any passenger exit the vehicle at
a safe distance from the roadway.

Take the spare wheel out of its carrier
(page 266).Lifting the vehicle

Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
(not included) or other sizable objects.
When changing wheel on a level surface:

Place one chock in front of and one be-
hind the wheel that is diagonally oppo-
site to the wheel being changed.
When changing wheel on a hill:

Place chocks on the downhill side
blocking both wheels of the other axle.

Take the two-piece wheel wrench and
the jack out of the rear cargo compart-
ment (
page 264). Assemble wheel
wrench.
Warning!
G
The dimensions of the spare wheel are dif-
ferent from those of the road wheels. As a
result, the vehicle handling characteristics
change when driving with a mounted spare
wheel. Adapt your driving style accordingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted,
make sure proper tire pressure and do not
exceed vehicle speed of 50 mph (80 km / h).
Drive to the nearest Mercedes-Benz Light
Truck Center as soon as possible to have the
spare wheel replaced with a regular road
wheel.
Never operate the vehicle with more than
one spare wheel mounted.
iOpen door only when conditions are
safe to do so.

285 Practical hints
Flat tire

On wheel to be changed, loosen but do
not yet remove the wheel bolts
(approximately one full turn with
wrench).
The jack take-up brackets are located di-
rectly behind the front wheel housings and
in front of the rear wheel housings.1Take-up bracket
2Jack

Place jack on firm ground.

Position jack2 under the take-up
bracket1 so that it is always vertical
(plumb-line) as seen from the side,
even if the vehicle is parked on an in-
cline.

Jack up the vehicle until the wheel is a
maximum of 1.2 in (3 cm) from the
ground. Never start engine while vehi-
cle is raised.
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 parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use, es-
pecially on hills. Always try to use the jack
on level surface. Make sure that the jack
arm is fully seated in the jack take-up brack-
et. Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.
!Do not position the jack on the body of
the vehicle, as this may cause damage
to the vehicle.

286 Practical hintsFlat tireRemoving the wheel

1-5Wheel bolts

Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1 to 5), until all bolts are tight.
Observe a tightening torque of
110 lb-ft (150 Nm).

Store jack and tool kit.Warning!
G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
110 lb-ft (150 Nm).
iThe removed road wheel cannot be
stored in the spare wheel carrier, but
should be transported in the rear cargo
compartment wrapped in a protective
cover supplied with the vehicle.
The protective cover is located in the
rear cargo compartment behind the
cover in the right side trim panel.

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

which is flammable and explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking etc.
!Never loosen or detach battery termi-
nal clamps while the engine is running
or the key is in the steering lock. Other-
wise the alternator and other electronic
components could be severely dam-
