ENGINE OIL CHECK
Diesel Engine
See your engine operator’s manual for information on checking and
adding engine oil as well as engine oil specifications, capacities and
required maintenance.
Gasoline Engine
Checking the Engine Oil
1. Make sure the vehicle is on level ground.
2. Turn the engine off and wait 15 minutes for the oil to drain into the
oil pan.
3. Set the parking brake and make sure the gearshift is securely latched
in positionP.
4. Open the hood. Protect yourself from engine heat.
5. Locate and carefully remove the engine oil level dipstick.
6. Wipe the dipstick clean. Insert the dipstick fully, then remove it
again.
•If the oil level is between the lower and upper holes, the oil level
is acceptable. DO NOT ADD OIL.
•If the oil level is below the lower hole, add enough oil to raise the
level within the lower and upper holes.
•Oil levels above the upper hole may cause engine damage. Some
oil must be removed from the engine by an authorized dealer.
7. Put the dipstick back in and make sure it is fully seated.
Adding Engine Oil
Note:Do not remove the engine oil level dipstick or the filler cap when
the engine is running.
Note:Do not add engine oil further than the MAX mark. Oil levels above
the MAX mark may cause engine damage.
Only use oils certified for gasoline engines by the
American Petroleum Institute (API). An oil with this
trademark symbol conforms to the current engine and
emission system protection standards and fuel
economy requirements of the International Lubricants
Specification Advisory Council (ILSAC), comprised of
U.S. and Japanese automobile manufacturers.
1. Check the engine oil level.

TRANSMISSION FLUID CHECK
Allison Automatic Transmissions
See yourAllison Automatic Transmission Operator’s Manualfor
scheduled transmission fluid checks and change intervals. Your
transmission does not consume fluid. However, the fluid level should be
checked if the transmission is not working properly, i.e., if the
transmission slips or shifts slowly or if you notice some sign of fluid
leakage.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is at normal operating
temperature (approximately 20 miles [30 kilometers]). Verify that the
transmission fluid temperature gauge, located on the instrument cluster,
is within the normal range.
1. Drive the vehicle 20 miles (30 kilometers) or until it reaches normal
operating temperature.
2. Park the vehicle on a level surface and engage the parking brake.
3. With the engine running, parking brake engaged and your foot on the
brake pedal, move the gearshift lever through all of the gear ranges.
Allow sufficient time for each gear to engage.
4. Latch the gearshift lever in positionNorPand leave the engine
running.
5. Remove the dipstick, wiping it clean with a clean, dry, lint-free rag.
6. Install the dipstick making sure it is fully seated in the filler tube.
7. Remove the dipstick and inspect the fluid level. The fluid should be
in the designated area for normal operating temperature or ambient
temperature.
If you must add transmission fluid, see yourAllison Automatic
Transmission Operator’s Manualfor the correct fluid type.Use of a
non-approved automatic transmission fluid may cause internal
transmission component damage.
Fluid levels above the safe range may result in transmission failure. An
overfill condition of transmission fluid may cause shift or engagement
concerns or possible damage.
TorqShift® Automatic Transmission
See theScheduled Maintenancechapter for scheduled intervals for
fluid checks and changes. Your transmission does not consume fluid.
However, the fluid level should be checked if the transmission is not
working properly, i.e., if the transmission slips or shifts slowly or if you
notice some sign of fluid leakage.

Low Fluid Level
Do not drive the vehicle if there is
no indication of fluid on the dipstick
and the ambient temperature is
above 50°F (10°C).
Correct Fluid Level
The fluid should be checked at
normal operating temperature
196°F-216°F (91°C-102°C) on a
level surface. The normal operating
temperature can be reached after approximately 20 miles (30 kilometers)
of driving.

DRIVESHAFT
Check the universal joints for any evidence of wear or looseness at the
regular lubrication interval. Stop the vehicle immediately, should
driveshaft vibrations occur, to avoid possible hazardous consequences or
damage to other components.
REAR AXLE FLUID
Your rear axle may be filled with an optional synthetic lubricant which
allows the use of extended service intervals. A tag on the filler plug
identifies the use of the synthetic lubricant.
Only use a lubricant that meets manufacturer specifications. See the
Capacities and Specificationschapter.Use of a non-approved rear
axle lubricant may cause internal axle component damage.

POWER STEERING FLUID CHECK
Note:To avoid damage to the power steering system, do not operate the
vehicle with a low power steering fluid level.
Note:If adding fluid is necessary, use only the appropriate fluid. See the
Capacities and Specificationschapter. A low fluid level may indicate a
leak in the power steering system. Inspect the power steering system
and repair the leak or see your dealer or a qualified technician for
service. See theScheduled Maintenancechapter for the recommended
service intervals.
Check the fluid level when it is at ambient temperature, 20°F–80°F
(-7°C–25°C):
1. Set the parking brake, then start the engine.
2. Shift into positionNorP(if equipped) (automatic transmission) or
first gear (manual transmission) and turn the engine off.
3. Open the hood.
4. Clean the top of the power steering fluid reservoir.
5. Remove the dipstick from the reservoir and wipe the dipstick clean.
6. Reinstall the dipstick. Remove it again and check the fluid level.
Check the MAX. COLD side of the
dipstick if the fluid is cool or warm to
the touch (approximately 68°F-120°F
[20°C-49°C]). The fluid level should
be within the FULL range. If
necessary, add fluid in small amounts,
continuously checking the level, until
it reaches the proper level.
Check the MAX. HOT side of the
dipstick if the fluid is too hot to
touch (approximately 176°F–230°F
[80°C-110°C]). The fluid level
should be within the FULL range.
If necessary, add fluid in small
amounts, continuously checking the
level, until it reaches the proper
level.
Whenever the dipstick is installed, make sure it is properly seated and
tightened securely.
The fluid level can also be checked by looking at the see-through plastic
reservoir. Make sure that the fluid is within the minimum and maximum
fluid range as marked on the reservoir.

Your vehicle is equipped with two or three maintenance-free batteries
mounted in a covered tray located on the left frame rail. The covered
battery tray, depending upon application, may also have one or two steps
attached.
Covered battery tray shown
(battery tray with steps
similar).The two rubber straps on
top of the cover must be pulled up
and moved to the side of the
battery in order to remove the lid.
Battery tray with cover
removed.
For longer, trouble-free operation,
keep the top of the battery clean
and dry. Also, make certain the
battery cables are always tightly
fastened to the battery terminals.
If you see any corrosion on the battery or terminals, remove the cables
from the terminals and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water.
It is recommended that the negative battery cable terminal be
disconnected from the battery if you plan to store your vehicle for an
extended period of time. This will minimize the discharge of your battery
during storage.
If the engine cranks but does not start, remove the battery box cover
and check the 40 amp inline fuse located on the battery cable above the
battery.
Because your vehicle’s engine is electronically controlled by a computer,
some control conditions are maintained by power from the battery. When
the battery is disconnected or a new battery is installed, the engine must
relearn its idle and fuel trim strategy for optimum driveability and
performance. To begin this process:
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift in positionP(automatic transmission) or neutral
(manual transmission), turn off all accessories and start the engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
