Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message
will flash in the EVIC display for approximately 10 sec-
onds after a single chime has sounded to indicate the next
scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the
engine oil change interval may fluctuate dependent upon
your personal driving style.

CAUTION! (Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of
your vehicle and also allow extended maintenance
intervals. Do not use chemical flushes in these
components as the chemicals can damage your
engine, transmission, power steering or air condi-
tioning. Such damage is not covered by the New
Vehicle Limited Warranty. If a flush is needed
because of component malfunction, use only the
specified fluid for the flushing procedure.
Engine Oil
Checking Oil Level
To assure 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. Always
maintain the oil level within the SAFE zone on the
dipstick. Adding 1 quart (0.9 L) 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.
424 MAINTAINING YOUR VEHICLE

WARNING!
•Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi-
tioning system. Some unapproved refrigerants are
flammable and can explode, injuring you. Other
unapproved refrigerants or lubricants can cause
the system to fail, requiring costly repairs. Refer to
Section 3 of the Warranty Information book, lo-
cated on the DVD, for further warranty informa-
tion.
•The air conditioning system contains refrigerant
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.
Refrigerant Recovery and Recycling
R-134a air conditioning refrigerant is a hydrofluoro-
carbon (HFC) that is endorsed by the Environmental
Protection Agency and is an ozone-saving product. How-
ever, 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
Sealers, Stop Leak Products, Seal Conditioners, Compres-
sor Oil, and Refrigerants.
A/C Air Filter — If Equipped
Refer to the “Maintenance Schedule” in Section 8 for the
proper maintenance intervals.
WARNING!
Do not remove the A/C Air Filter while the blower is
operating or personal injury may result.
430 MAINTAINING YOUR VEHICLE

Draining Fluid
First remove the fill plug (1), then the drain plug (2).
Recommended tightening torque for the drain and fill
plugs is 15–25 ft lbs (20–34 N·m).
CAUTION!
Do not over-tighten the plugs. You could damage
them and cause a leak.
Lubricant Selection
Use only manufacturer’s recommended fluid. Refer to
“Fluids, Lubricants, and Genuine Parts” in this section
for the correct fluid type.
Frequency of Fluid Change
Under normal operating conditions, the fluid installed at
the factory will give satisfactory lubrication for the life ofthe vehicle. Fluid changes are not necessary unless the
fluid becomes contaminated with water. Change the fluid
immediately if contaminated with water.
Front/Rear Axle Fluid
Fluid Level Check
The lubricant level should be at bottom edge of the oil fill
hole.
Adding Fluid
Add lubricant only at the fill hole and only to the level
specified above.
Lubricant Selection
Use only manufacturer’s recommended lubricant. Refer
to “Fluids, Lubricants, and Genuine Parts” in this section
for the correct fluid type.7
