Adjusting headlamp aim
Correct headlamp adjustment is extremely important.
To check and readjust a headlamp, follow steps 1
through 7.
Please note:
•High beam adjustments simultaneously aim the low
beam.
•Vehicle should have a normal trunk load.1. Park vehicle on level surface approximately 6 inches
(152 mm) from a vertical test screen or wall. The
centerline of the vehicle must be at a 90° angle to
the test screen.
2. (High beams on):
Using a carpenter’s level, align and mark a vertical
centerline (1) on the test screen for each headlamp
lens at a distance of 25
3/4inches (654 mm) from
the vertical centerline. As a check, the distance
between centerlines should be 51
1/2inches
(1308 mm). The star emblem on the hood may be
used to determine the vehicle centerline. If the
distance does not check, have the system verified at
an authorized Mercedes-Benz Light Truck Center.
3. Move vehicle on the level surface 25 feet (7.6 m)
straight back from the wall.
4. Open hood.

Simultaneously turn adjusting screws (1 and 2 on
page 261 or 262) counterclockwise to adjust
headlamp downward, clockwise upward) equally
until bubble in the level (7 on page 261) is centered
on the “0” mark.
Graduations:
screw 1: 0.50° pitch,
screw 2: 0.67° pitch.
6. Horizontal headlamp aim (High beams on):
Turn adjusting screw (2) (left headlamp:
counterclockwise to adjust to the left, clockwise to
the right [right headlamp in opposite direction])
until the headlamp (high beam pattern) is centered
about the vertical centerline (1) as shown.
The left and right headlamps must be adjusted
individually.7. For proper aim, the indicator (8 on page 261) should
align with the “0” mark after horizontal adjustment.
Graduations: 0.33° pitch.
Note:
If it is not possible to obtain a proper headlamp
adjustment, have the system checked at your authorized
Mercedes-Benz Light Truck Center.

Engine cleaning
Prior to cleaning the engine compartment make sure to
protect electrical components and connectors from the
intrusion of water and cleaning agents.
Corrosion protection, such as MB Anticorrosion Wax
should be applied to the engine compartment after
every engine cleaning. Before applying, all control
linkage bushings and joints should be lubricated. The
poly-V-belt and all pulleys should be protected from any
wax.
Ve h i c l e w a s h i n g
Do not use hot water or wash your vehicle in direct
sunlight. Use only a mild car wash detergent, such as
Mercedes-Benz approved Car Shampoo.
Thoroughly spray the vehicle with a diffused jet of
water. Direct only a very weak spray towards the
ventilation intake. Use plenty of water and rinse the
sponge and chamois frequently.
Rinse with clear water and thoroughly wipe dry with a
chamois. Do not allow cleaning agents to dry on the
finish.Due to the width of the vehicle, prior to running the
vehicle through an automatic car wash, fold back the
outside mirrors to prevent them from getting damaged.
In the winter, thoroughly remove all traces of road salt
as soon as possible.
When washing the underbody, do not forget to clean the
inner sides of the wheels.
Ornamental moldings
For regular cleaning and care of very dirty chrome-
plated parts, use a chrome cleaner.
Headlamps, taillamps, turn signal lenses
Use a mild car wash detergent, such as Mercedes-Benz
approved Car Shampoo, with plenty of water.
To prevent scratches, never apply strong force and use
only a soft, non-scratchy cloth when cleaning the lenses.
Do not attempt to wipe dirty lenses with a dry cloth or
sponge.
