SERVICING AND MAINTENANCE345
Checking Oil Level — Gas Engine
To ensure proper lubrication of your vehicle's
engine, the engine oil must be maintained at
the correct level. Check the oil level at regular
intervals, such as every fuel stop. The best time
to check the engine oil level is about five
minutes after a fully warmed up engine is shut
off.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
readings. Always maintain the oil level within
the SAFE zone on the dipstick. Adding one quart
of oil when the reading is at the bottom of the
SAFE zone will result in a reading at the top of
the safe zone on these engines.
Checking Oil Level — Diesel Engine
To ensure proper lubrication of your vehicle's
engine, the engine oil must be maintained at
the correct level. Check the oil level at regular
intervals. The best time to check the oil level is
before starting the engine after it has been parked overnight. When checking oil after oper
-
ating the engine, first ensure the engine is at full
operating temperature, then wait for
30 minutes after engine shutdown to check the
oil.

Engine Oil Dipstick

Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
readings. Add oil only when the level on the
dipstick is below the “ADD” mark. The total
capacity from the ADD mark to the Full mark is
2 Quarts (1.9Liters). Never operate the engine with oil level below
the “ADD” mark or above the upper “SAFE”
mark.
Adding Washer Fluid
The fluid reservoir is located under the hood
and should be checked for fluid level at regular
intervals. Fill the reservoir with windshield
washer solvent only (not radiator antifreeze).
When refilling the washer fluid reservoir, take
some washer fluid and apply it to a cloth or
towel and wipe the wiper blades clean. This will
help blade performance.
To prevent freeze-up of your windshield washer
system in cold weather, select a solution or
mixture that meets or exceeds the temperature
range of your climate. This rating information
can be found on most washer fluid containers.
CAUTION!
Overfilling or underfilling will cause oil
aeration or loss of oil pressure. This could
damage your engine.
1 — ADD Range
2 — Full Mark
3 — SAFE Range
CAUTION!
Overfilling or underfilling the crankcase will
cause oil aeration or loss of oil pressure. This
could damage your engine.

3. Remove the air cleaner filter element from
the housing assembly.

Air Cleaner Filter

Engine Air Cleaner Filter Installation
NOTE:
Inspect and clean the housing if dirt or debris is
present before replacing the air filter element.

1. Install the air cleaner filter element into the housing assembly with the air cleaner filter
inspection surface facing downward.

2. Install the air cleaner cover onto the housing assembly locating tabs. 3. Install screws to secure the air cleaner
cover to the housing assembly.
Air Conditioner Maintenance
For best possible performance, your air condi -
tioner should be checked and serviced by an
authorized dealer at the start of each warm
season. This service should include cleaning of
the condenser fins and a performance test.
Drive belt tension should also be checked at
this time.
Refrigerant Recovery And Recycling R-134a
— If Equipped
R-134a Air Conditioning Refrigerant is a hydro -
fluorocarbon (HFC) that is an ozone-friendly
substance. The manufacturer recommends
that air conditioning service be performed by an
authorized dealer or other service facilities
using recovery and recycling equipment.
NOTE:
Use only manufacturer approved A/C system
PAG compressor oil and refrigerants.
1 — Air Cleaner Filter
2 — Air Cleaner Filter Inspection Surface
WARNING!
Use only refrigerants and compressor lubri -
cants approved by the manufacturer for
your air conditioning system. Some unap -
proved refrigerants are flammable and can
explode, injuring you. Other unapproved
refrigerants or lubricants can cause the
system to fail, requiring costly repairs.
Refer to Warranty Information Book, for
further warranty information.
The air conditioning system contains refrig -
erant under high pressure. To avoid risk of
personal injury or damage to the system,
adding refrigerant or any repair requiring
lines to be disconnected should be done by
an experienced technician.
CAUTION!
Do not use chemical flushes in your air
conditioning system as the chemicals can
damage your air conditioning components.
Such damage is not covered by the New
Vehicle Limited Warranty.

SERVICING AND MAINTENANCE369
Use the following procedure to check the trans -
mission fluid level properly:

1. Monitor the transmission temperature using the instrument cluster display, and
operate the vehicle as required to reach
the normal operating temperature. If the
transmission is not functioning properly, or
the vehicle cannot be driven, see the NOTE
and CAUTION below about checking the
fluid level at colder temperatures.

2. Park the vehicle on level ground.
3. Run the engine at normal idle speed for at least 60 seconds, and leave the engine
running for the rest of this procedure.
4. Fully apply the parking brake, and press the brake pedal.
5. Place the gear selector momentarily into each gear position (allowing time for the
transmission to fully engage in each posi -
tion), ending with the transmission in PARK.
6. Remove the dipstick, wipe it clean and rein -
sert it until seated. 7. Remove the dipstick again and note the
fluid level on both sides. The fluid level
reading is only valid if there is a solid
coating of oil on both sides of the dipstick.
Note that the holes in the dipstick will be full
of fluid if the actual level is at or above the
hole. The fluid level should be between the
“HOT” (upper) reference holes on the
dipstick at normal operating temperature. If
the fluid level is low, add fluid through the
dipstick tube to bring it to the proper level.
Do not overfill. Use ONLY the specified fluid
(refer to "Fluids And Lubricants" in “Tech -
nical Specifications” for fluid specifica -
tions). After adding any quantity of oil
through the dipstick tube, wait a minimum
of two minutes for the oil to fully drain into
the transmission before rechecking the
fluid level.
NOTE:
If it is necessary to check the transmission
below the operating temperature, the fluid level
should be between the two “COLD” (lower)
holes on the dipstick with the fluid at 60-70°F /
16-21°C. Only use the COLD region of the
dipstick as a rough reference when setting the
fluid level after a transmission service or fluid change. Re-check the fluid level, and adjust as
required, once the transmission reaches
normal operating temperature.
8. Reinsert the dipstick. Check for leaks.
Release the parking brake.
NOTE:
If it is necessary to check the transmission
below the operating temperature, the fluid level
should be between the two COLD (lower) holes
on the dipstick with the fluid at 68-86°F /
20-30°C. Only use the COLD region of the
dipstick as a rough reference when setting the
fluid level after a transmission service or fluid
change. Re-check the fluid level, and adjust as
required, once the transmission reaches
normal operating temperature.
CAUTION!
If the fluid temperature is below 50 °F (10
°C) it may not register on the dipstick. Do not
add fluid until the temperature is elevated
enough to produce an accurate reading. Run
the engine at idle, in PARK, to warm the fluid.
