270SERVICING AND MAINTENANCE
CHECKING OIL LEVEL

To ensure proper engine lubrication, 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.
There are four possible dipstick types:
Crosshatched zone.
Crosshatched zone marked SAFE.
Crosshatched zone marked with MIN at the
low end of the range and MAX at the high end of
the range.
Crosshatched zone marked with dimples at the
MIN and the MAX ends of the range.
NOTE:Always maintain the oil level within the crosshatch
markings on the dipstick.
Adding 1 quart (1.0 liter) of oil when the reading is
at the low end of the dipstick range will raise the oil
level to the high end of the range marking.
ADDING WASHER FLUID
The instrument cluster display will indicate when
the washer fluid level is low. When the sensor
detects a low fluid level, the windshield will light on
the vehicle graphic outline and the “WASHER
FLUID LOW” message will be displayed.
The fluid reservoir for the windshield washers and
the rear window washer is shared. The fluid
reservoir is located in the engine compartment, be
sure to check the 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 clean the wiper blades,
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.
MAINTENANCE-FREE BATTERY
Your vehicle is equipped with a maintenance-free
battery. Water will never have to be added, and
periodic maintenance is not required.
CAUTION!
Overfilling or underfilling the crankcase will
cause aeration or loss of oil pressure. This could
damage your engine.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite and
burn you. Care must be exercised when filling or
working around the washer solution.
WARNING!
Battery fluid is a corrosive acid solution and
can burn or even blind you. Do not allow
battery fluid to contact your eyes, skin, or
clothing. Do not lean over a battery when
attaching clamps Úpage 255. If acid
splashes in eyes or on skin, flush the area
immediately with large amounts of water.
Battery gas is flammable and explosive. Keep
flame or sparks away from the battery. Do not
use a booster battery or any other booster
source with an output greater than 12 Volts.
Do not allow cable clamps to touch each
other.
Battery posts, terminals, and related accesso -
ries contain lead and lead compounds. Wash
hands after handling.

SERVICING AND MAINTENANCE285
Selection Of Lubricant
It is important to use the proper transmission fluid
to ensure optimum transmission performance and
life. Use only the manufacturer's specified
transmission fluid Úpage 323. It is important to
maintain the transmission fluid at the correct level
using the recommended fluid.
NOTE:No chemical flushes should be used in any trans -
mission; only the approved lubricant should be
used.
FRONT/REAR AXLE FLUID
For normal service, periodic fluid level checks are
not required. When the vehicle is serviced for other
reasons the exterior surfaces of the axle assembly
should be inspected. If gear oil leakage is
suspected inspect the fluid level.
Front Axle Fluid Level Check
The front axle oil level needs to be no lower than
1/8 inch (3 mm) below the bottom of the fill hole.
The front axle fill and drain plugs should be
tightened to 22 to 29 ft lbs (30 to 40 N·m).
Rear Axle Fluid Level Check
The rear axle oil level needs to be no lower than
1/8 inch (3 mm) below the bottom of the fill hole.
The rear axle fill and drain plugs should be
tightened to 22 to 29 ft lbs (30 to 40 N·m).
Selection Of Lubricant
Use only the manufacturer's recommended fluid
Ú page 323.
TRANSFER CASE
Fluid Level Check
For normal service, periodic fluid level checks are
not required. When the vehicle is serviced for other
reasons the exterior surfaces of the transfer case
assembly should be inspected. If oil leakage is
suspected inspect the fluid level.
Adding Fluid
With the vehicle in a level position, fill the transfer
case to bottom edge of fill plug opening.
Drain
First remove fill plug, then remove drain plug.
Recommended tightening torque for drain and fill
plugs is 15 to 25 ft lbs (20 to 34 N·m).
Selection Of Lubricant
Use only the manufacturer's recommended fluid
Úpage 323.
CAUTION!
Using a transmission fluid other than the
manufacturer recommended fluid may cause
deterioration in transmission shift quality and/or
torque converter shudder Ú page 323.
CAUTION!
Do not overtighten the plugs as it could damage
them and cause them to leak.
CAUTION!
Do not overtighten the plugs as it could damage
them and cause them to leak.
CAUTION!
When installing plugs, do not overtighten. You
could damage them and cause them to leak.
