2005 JEEP LIBERTY Diesel

NOTE:DaimlerChrysler Corporation recommends that
this vehicle should be operated using Diesel fuel with 15
ppm Sulfur or less, where it is available.
WARNING!
Do not use alcohol or gasoline as a fuel blending
agent. They can be unstable under certain conditions
and hazardous or explosive when mixed with diesel
fuel.
Diesel fuel is seldom completely free of water. To prevent
fuel system trouble, drain the accumulated water from
the fuel/water separator using the fuel/water separator
drain provided. If you buy good quality fuel and follow
the cold weather advice above, fuel conditioners should
not be required in your vehicle. If available in your area,
a high cetane “premium” diesel fuel may offer improved
cold-starting and warm-up performance.
FUEL TANK FILLER CAP (GAS CAP)
WARNING!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
CAUTION!
DO NOT put gasoline in your diesel vehicle (if
equipped). If you accidentally put gasoline in your
vehicle, DO NOT start the engine. This will cause
damage to the fuel system. Have the fuel system
flushed.
STARTING AND OPERATING 281

If the coolant temperature of a vehicle equipped with a
diesel engineapproaches the “H” (hot mark) a warning
chime will sound to alert the driver. The air conditioning
system will turn off automatically and power loss will
occur until the engine temperature returns to the normal
range.
If the overheating condition persists a continuous chime
will sound to alert the driver. Reduce the vehicle speed
and or stop the vehicle while allowing the engine to idle
and cool the engine.JACKING AND TIRE CHANGING
WARNING!
•Getting under a jacked-up vehicle is dangerous.
The vehicle could slip off the jack and fall on you.
You could be crushed. Never get any part of your
body under a vehicle that is on a jack. If you need
to get under a raised vehicle, take it to a service
center where it can be raised on a lift.
•The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or
slippery areas.

2.8L TURBO DIESEL ENGINE
308 MAINTAINING YOUR VEHICLE

Engine Oil Selection (Diesel Engines)
For best performance and maximum protection for all
engines under all types of operating conditions, the
manufacturer recommends using synthetic engine oils
that are API Certified (SL/CF), and meet the require-
ments of DaimlerChrysler Material Standard MS-10725.
Engine Oil Viscosity (2.8L Diesel Engines)
Use SAE 0W-40 Mobil 1Synthetic Engine Oil that
meets API categories CF or better and the requirements
of DaimlerChrysler Material Standard MS-10725. If you
cannot find SAE 0W-40, then SAE 5W-40 Mobil 1
Synthetic Engine Oil is acceptable. Any engine oil that
does not meet the manufacturer’s requirements should
not be used.
Lubricants which do not have both, the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber should not be used.
Synthetic Engine Oils — All Engines
There are a number of engine oils being promoted as
either synthetic or semi-synthetic. If you chose to use
such a product, use only those oils that are certified by
the American Petroleum Institute (API) to display the
symbol on the front of the container or the proper ACEA
category and show the recommended SAE viscosity
grade. Follow the service schedule that describes your
driving type.
Materials Added To Engine Oils
The manufacturerstrongly recommendsagainst the ad-
dition of any additives (other than leak detection dyes) to
engine oil. Engine oil is an engineered product and it’s
performance may be impaired by supplemental addi-
tives.

CAUTION!
Using a transmission fluid other than the manufac-
turer’s recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than the
manufacturer’s recommended fluid will result in
more frequent fluid and filter changes. Refer to
Recommended Fluids, Lubricants, and Genuine
Parts for correct fluid type.
Fluid Level Check – 3.7L Gasoline Engine (42RLE)
and 2.8L Diesel Engine (545RFE)
This fluid level should be checked when the engine is
fully warmed up and the fluid in the transmission is
heated to its normal operating temperature. Operation of
the transmission with an improper fluid level will greatly
reduce the life of the transmission and of the fluid.To check the automatic transmission fluid level properly,
the following procedure must be used:
1. The vehicle must be on level ground.
2. The engine should be running at curb idle speed for a
minimum of 60 seconds.
3. Fully apply parking brake.
4. Apply the brakes and shift the transmission into P
(Park).
5. The fluidMUSTbe checked with the transmission in
P (Park) to be sure that the fluid level is accurate.
6. Wipe the dipstick clean and reinsert until seated.
Remove dipstick and note reading.
At normal operating temperature (approximately 180° F
(82° C), the fluid level is correct if it is in the HOT region
