regular intervals, such as every fuel stop. The best time to
check the engine oil level is about five minutes after a
fully warmed engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain
the oil level in the “SAFE” range. Adding one quart of oil
when the reading is at the bottom of the “SAFE” range
will result in an oil level at the top of the “SAFE” range
on these engines.
NOTE:Fill engine oil one quart at a time.
CAUTION!
•Overfilling or underfilling will cause oil aeration or
loss of oil pressure. This could damage your engine.
•Operating the engine with the oil levels below the
safe zone, or operating with oil levels that exceed the
top of the safe zone may cause engine damage.
Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
Refer to “Maintenance Schedule” for further information.
NOTE: Under no circumstances should oil change inter-
vals exceed 6,000 miles (10,000 km) or six months,
whichever occurs first.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only
recommends full synthetic engine oils that meet the
American Petroleum Institute (API) categories of SN.

CAUTION!
Do not overtighten the plugs as it could damage them
and cause them to leak.
Rear Axle Fluid Level Check
The rear axle oil level needs to be no lower than 1/8 in (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).
CAUTION!
Do not overtighten the plugs as it could damage them
and cause them to leak.
Selection Of Lubricant
Use only the manufacturer’s recommended fluid. Refer
to “Fluids, Lubricants, and Genuine Parts” in “Maintain-
ing Your Vehicle” for further information.
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. Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Adding Fluid
Add fluid at the filler hole, until it runs out of the hole,
when the vehicle is in a level position.
