ENGINE OIL - DIESEL ENGINES
SAE VISCOSITY GRADE
CAUTION: Low viscosity oils must have the proper
API quality.
Only use engine oils that are labeled on the con-
tainer as meeting API (American Petroleum Insti-
tute) and/or DaimlerChrysler specifications MB
228.3, 228.5, 229.3, and 229.5, such as MOPARtSAE
15W-40 HD Diesel Engine Oil (e.g. MOPARtPart
No. 03798231AD), or equivalent.
Do not add any materials (other than leak detec-
tion dyes) to the engine oil. Engine oil is an engi-
neered product and it's performance may be impaired
by supplemental additives.
When topping off engine oil, only use oil of the
same quality grade and SAE classification.
Always refer to the following viscosity chart for the
proper viscosity grade based on ambient tempera-
ture. Select oil viscosity according to the lowest air
temperature expected before the next oil change.
The temperature limits given for the different SAE
classes should be regarded as guidelines which may
be exceeded temporarily to avoid excessively frequent
engine oil changes.
The following engine oils have been determined to
meet DaimlerChrysler requirements:

Do not blend other specific fuel additives with die-
sel fuel. They only result in unnecessary cost, and
may be harmful to the engine operation.
POWER STEERING FLUID
No fluid service required. Filled with Power Steer-
ing Fluid approved to MB 236.3, such as Mobil
ATF-D (Exxon Mobil Corporation) or equivalent.
OPERATION - AUTOMATIC TRANSMISSION
FLUID
The automatic transmission fluid is selected based
upon several qualities. The fluid must provide a high
level of protection for the internal components by
providing a lubricating film between adjacent metal
components. The fluid must also be thermally stable
so that it can maintain a consistent viscosity through
a large temperature range. If the viscosity stays con-
stant through the temperature range of operation,
transmission operation and shift feel will remain con-
sistent. Transmission fluid must also be a good con-
ductor of heat. The fluid must absorb heat from the
internal transmission components and transfer that
heat to the transmission case.

HOISTING CONDITIONS UNSTABLE. PROPERLY
SUPPORT OR SECURE VEHICLE TO HOISTING
DEVICE WHEN THESE CONDITIONS EXIST.
FLOOR JACK
When properly positioned, a floor jack can be used
to lift a vehicle. Support the vehicle in the raised
position with jack stands at the front and rear ends
of the frame rails.
CAUTION: Do not lift vehicle with a floor jack posi-
tioned under:
²An axle tube.
²A body side sill.
²A steering linkage component.
²A drive shaft.
²The engine or transmission oil pan.
²The fuel tank.
²A front suspension arm.

effect panels. If necessary, remove the wheels from
the lifted end of the vehicle and lower the vehicle
closer to the ground, to increase the ground clearance
at the opposite end of the vehicle. Install lug nuts on
wheel attaching studs to retain brake drums.
RAMP ANGLE
If a vehicle with flat-bed towing equipment is used,
the approach ramp angle should not exceed 15
degrees.
TOWING WHEN KEYS ARE NOT AVAILABLE
When the vehicle is locked and keys are not avail-
able, use a flat bed hauler. A Wheel-lift or Sling-type
device can be used provided all the wheels are lifted
off the ground using tow dollies.
MAINTENANCE SCHEDULES
DESCRIPTION
The use of special lubricant additives is not recom-
mended. The use of such additives may affect the
warranty rights. With regard to legal stipulations
concerning emissions control, please note that
engines have to be serviced and adjusted in accor-
dance with special instructions and using special
measuring equipment. Modifications to or interfer-
ence with the emissions control systems are not per-
missible.

miles or 16,000 km or 12 months.
²Maintenance service every 30,000 miles or
48,000 km.
Additional work must be carried out at yearly
intervals.
MAINTENANCE - WITH ASSYST MAINTENANCE
COMPUTER
ASSYST provides information on the best possible
timing for maintenance work.
When the next maintenance service is due, this
will be indicated in the multi-function display with
the wrench icon symbol displayed in km/miles or
days.
²One wrench icon showing indicates Oil Service
is necessary.
²Two wrench icons showing indicates Mainte-
nance Service is necessary ± displayed in km/miles or
days.
If the display shows the number of days, a clock
symbol will also appear in the multi-function display.You should have the maintenance performed
within the stated period/distance.
The service indicator will be reset after an oil ser-
vice and/or maintenance service has been performed.
REGULAR CHECK - UPS
To maintain the safe operation of the vehicle, it is
recommended that the following tasks be performed
on a regular basis (i.e. weekly or whenever the vehi-
cle is refueled). Check:
²Engine oil level
²Brake system - fluid level
²Battery - acid level
²Windshield washer system and headlamp clean-
ing system - fluid level
²Mechanical assemblies (e.g. engine, transmis-
sion, etc.) - check for leaks
²Condition of tires and tires pressures
²All exterior lights
SPECIAL MAINTENANCE REQUIREMENTS
If bodies built by manufacturers other than
DaimlerChrysler Corporation are fitted to the vehi-
cle, the maintenance requirements and lubrication
intervals specified by the body manufacturer must be
adhered to, in addition to all standard maintenance
requirements.
Coolant
Corrosion inhibitor/antifreeze concentration in the
coolant should be checked before the onset of winter
(once year in countries with high prevailing temper-
atures).
Replace the coolant every five years or 100,000
miles.
Dust Filter for Heating / Ventilation Replacement
The dust filter and the tailgate interior filter are to
be renewed during routine maintenance service. If
operating conditions are dusty, these filters should be
renewed more frequently.
ENGINE OIL CHANGE AND FILTER REPLACEMENT
At a minimum, change the engine oil and oil filter
once a year ± even if the vehicle mileage per year is
extremely low. For standard oil service schedules
refer to the chapter oil service and maintenance ser-
vice.
Once a Year
Select the viscosity of the engine oil (SAE classes)
according to the outside air temperature.
Only use engine oil approved by DaimlerChrysler
Corporation if following the ASSYST system guide-
lines.

FLUID
DIAGNOSIS AND TESTING - BRAKE FLUID
CONTAMINATION
Indications of fluid contamination are swollen or
deteriorated rubber parts.
Swollen rubber parts indicate the presence of
petroleum in the brake fluid.
To test for contamination, put a small amount of
drained brake fluid in clear glass jar. If fluid sepa-
rates into layers, there is mineral oil or other fluid
contamination of the brake fluid.
If brake fluid is contaminated, drain and thor-
oughly flush system. Replace master cylinder, ALB
Controller, caliper seals, Antilock Brakes hydraulic
unit and all hydraulic fluid hoses.
STANDARD PROCEDURE - BRAKE FLUID
LEVEL
Always clean the master cylinder reservoir and
caps before checking fluid level. If not cleaned, dirt
could enter the fluid.
The fluid fill level is indicated on the side of the
master cylinder reservoir (Fig. 13).
The correct fluid level is to the MAX indicator on
the side of the reservoir. If necessary, add fluid to the
proper level. (Refer to LUBRICATION & MAINTE-
NANCE/FLUID TYPES - DESCRIPTION).
SPECIFICATIONS
BRAKE FLUID
The brake fluid to be used in this vehicle must be
approved to MB 331.0, such as MOPARtpart num-
ber 0459625AC. If the approved product is not avail-
able, use a DOT 4 brake fluid: minimum dry boiling
point (ERBP) 500ÉF, minimum wet boiling point
(WERBP) 356ÉF, maximum viscosity 1500 mm
2/s,conforming to FMVSS 116 and ISO 4925. No other
type of brake fluid is recommended or approved for
usage in the vehicle brake system. Use only approved
brake fluid or an equivalent from a tightly sealed
container.
Use brake fluid
CAUTION: Never use reclaimed brake fluid or fluid
from an container which has been left open. An
open container of brake fluid will absorb moisture
from the air and contaminate the fluid.
CAUTION: Never use any type of a petroleum-based
fluid in the brake hydraulic system. Use of such
type fluids will result in seal damage of the vehicle
brake hydraulic system causing a failure of the
vehicle brake system. Petroleum based fluids would
be items such as engine oil, transmission fluid,
power steering fluid, etc.
FLUID RESERVOIR
REMOVAL
(1) Using a suction gun remove as much brake
fluid from the reservoir as possible (Fig. 14).
(2) Disconnect the electrical connector for the
brake fluid level indicator (Fig. 14).
(3) Remove the fluid reservoir (Fig. 14).Seal off
the ends and bore holes with plugs.
INSTALLATION
(1) Install the fluid reservoir and fill with fluid
(Fig. 14).
(2) Bleed the brake system.
