Important!
The FSS indicator is not an engine oil level indicator.
See page 89 for engine oil level indicator.
Notes:
When disconnecting vehicle battery for one or more
days at a time, such days will not be counted. Any such
days not counted by the FSS can be added by your
Mercedes-Benz Light Truck Center.
The interval between services is determined by the type
of driving for which the vehicle is used. For example,
driving at extreme speeds, and cold starts combined
with short distance driving in which the engine does not
reach normal operating temperature, reduce the interval
between services.
Following a completed A or B service the Mercedes-
Benz Light Truck Center sets the counter mileage to
10 000 miles (Canada: 15 000 km) and 365 days.
The counter can also be set by any individual. To do so:
1. Turn the key in steering lock to position 2.
2. Immediately press button (1) twice within one
second.3. The present status for days or distance is displayed.
Within 10 seconds turn key in steering lock to
position 0.
4. Press and hold button (1), while turning key in
steering lock to position 2 again. The present status
for days or distance is displayed once more.
Continue to hold button (1).
After approximately 10 seconds a signal sounds, and
the display shows 10 000 miles (Canada: 15 000 km)
for approximately 10 seconds.
5. Release button (1).
If the FSS counter was inadvertently reset, have it
corrected at a Mercedes-Benz Light Truck Center.
Notes:
The FSS allows for distances between 10 000 miles
(Canada: 15 000 km) and 20 000 miles (Canada:
30 000 km), or from 365 to 730 days between services.
However you choose to set your reference numbers, the
scheduled services as posted in the Service Booklet
must be followed to properly care for your vehicle.

Replacing bulbs
Rear lamps Notes on bulb replacement


Use only 12-volt bulbs of the same type
and with the specified watt rating.


Switch lights off before changing a bulb
to prevent short circuits.


Always use a clean lint-free cloth when
handling bulbs.


Your hands should be dry and free of oil
and grease.


If the newly installed bulb does not light
up, visit an authorized Mercedes-Benz
Light Truck Center.


Have the LEDs and bulbs for the follow-
ing lamps replaced by an authorized
Mercedes-Benz Light Truck Center:

or rear view mirrors

Warning!
G
Keep bulbs out of reach of children.
Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing
a bulb.
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.

Oil Pump, Location

The oil pump (crescent-type pump) (6) is installed in the torque converter housing behind the torque
converter and is driven by the drive flange of the torque converter. See Fig. 51
.
Oil Pump, Task

To produce the necessary oil pressure for the hydraulic sequences.
Oil Pump, Design

An external gear (6a) which is m ounted eccentrically in the pump housi ng is located on the internal gear
(6b) which is connected to the drive flange (6b). The crescent (6c) drives the external gear (6a).
Oil Pump, Function

When the engine is running oil is delivered through th e suction gallery (6e) along the top and bottom side
of the crescent (6c) to the pr essure chamber (6d) of the housin
g. The meshing of the teeth prevents oil

IGNITION COILS, LOCATION - GF15.10-P-3102-01A
Fig. 5: Identifying Cylinder 1 To 6 Ignition Coil - Location On Engine 112
Spark plugs, locationOne or two spark plugs are
located in the cylinder head
per cylinder.
Spark plugs, taskThe spark plugs ignite the
suctioned and compressed
fuel-air mixture due to arcing
between the electrodes.
Spark plugs, designIn the manufacturer's specific
type symbols, all the spark
plug features are assigned (e.
g. heat rating, shape of
seating, thread, width across
flats, electrode material,
spark position).
Spark plugs, functionThe ignition voltage travels to
the spark plugs from directly
connected ignition coils or
over the ignition lines from
the ignition coils causing
arcing in the air gap between
the center and ground
electrodes.

RISK OF INJURY CAUSED BY PINCHING OR JAMMING WHEN WORKING ON LOADED SPRINGS OR SPRING BODIES
- AS00.00-Z-0001-01A
Use only approved clamping devices; shield off hazard area if necessary. Inspect special tools for damage
and proper operation (visual inspection). Wear protective gloves.
Risk of pinching and jamming body parts when working on pre-loaded components.
When loosening or removing components that are under significant load, there is a risk of serious injury if
non-approved if clamping devices are used.
Safety instructions/precautions
When conducting repair work on springs, spring bodies, spring-type actuators and other components under
tension use approved clamping devices only .
Spring compressor
The spring compressor should never be clamped or released using an impact wrench.
Check clamping devices
The spindle must be undamaged and allow ease of movement.
The clamping plates must not be deformed.
Note arrangement of clamping plates to springs.
If the device is damaged or malfunctioning, it must be returned to the manufacturer.
The coil diameter of the spring should match the groove in the clamping plate.
Wear protective gloves during all operations.
RISK OF INJURY. SKIN OR EYE INJURIES MAY RESULT WHEN HANDLING HOT OR GLOWING OBJECTS. - AS00.00-
Z-0002-01A
Wear protective gloves, protective clothing and (where necessary) safety glasses.
Risk of injury
Unprotected contact with hot or glowing objects may cause severe burns to the skin and eyes.
If glowing objects come into contact with water, hot steam or hot splashing water may result in severe skin and
eye burns.
Severe and possibly permanent injuries may result if hot or glowing objects come into contact with unprotected
skin or eyes.
Fire ma
y result if glowing objects come into contact with flammable materials or substances.
