Once A Month Or Before A Long Trip:
• Check engine oil level.
• Check windshield washer fluid level.
• Check the tire inflation pressures and look for unusualwear or damage. Rotate at the first sign of irregular wear.
• Check the fluid levels of the coolant reservoir, brake master cylinder, power steering and automatic transmis -
sion (six-speed only), and fill as needed.
• Check function of all interior and exterior lights.Maintenance Plan
Required Maintenance
Refer to the maintenance plan on the following pages for
required maintenance.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
• Change oil and filter.
• Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil indicator system turns on.
• Inspect engine cooling system protection and hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty or off-road conditions.
• Inspect battery and clean and tighten terminals as required.
• Inspect automatic transmission fluid if equipped with dipstick.
• Inspect brake pads, shoes, rotors, drums, hoses and park brake.

416 SERVICING AND MAINTENANCE
Checking Oil Level — Gas Engine
To assure 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 main-
tain 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.
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 anti -
freeze). 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.
After the engine has warmed up, operate the defroster for a
few minutes to reduce the possibility of smearing or freezing
the fluid on the cold windshield. Windshield washer solu-
tion used with water as directed on the container, aids
cleaning action, reduces the freezing point to avoid line clog
-
ging, and is not harmful to paint or trim.
CAUTION!
Overfilling or underfilling will cause oil 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.

Refrigerant Recovery And Recycling R-134a — If
Equipped
R-134a Air Conditioning Refrigerant is a hydrofluorocarbon
(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.
Refrigerant Recovery And Recycling — R–1234yf
R–1234yf Air Conditioning Refrigerant is a hydrofluo-
roolefin (HFO) that is endorsed by the Environmental
Protection Agency and is an ozone-friendly substance with a
low global-warming potential. The manufacturer recom -
mends that air conditioning service be performed by an
authorized dealer using recovery and recycling equipment.
NOTE:
Use only manufacturer approved A/C system PAG
compressor oil, and refrigerants.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 unap -
proved refrigerants or lubricants can cause the system
to fail, requiring costly repairs. Refer to Warranty Infor -
mation Book, for further warranty information.
• 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.
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.

(Continued)
NOTE:
Wheel Valve Stem must be replaced as well when installing
new tires due to wear and tear in existing tires.
Keep dismounted tires in a cool, dry place with as little expo-
sure to light as possible. Protect tires from contact with oil,
grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for wear
and correct cold tire inflation pressures. The manufacturer
strongly recommends that you use tires equivalent to the
originals in size, quality and performance when replacement
is needed. Refer to the paragraph on “Tread Wear Indica -
tors” in this section. Refer to the Tire and Loading Informa -
tion placard or the Vehicle Certification Label for the size
designation of your tire. The Load Index and Speed Symbol
for your tire will be found on the original equipment tire
sidewall.
See the Tire Sizing Chart example found in the “Tire Safety
Information” section of this manual for more information
relating to the Load Index and Speed Symbol of a tire. It is recommended to replace the two front tires or two rear
tires as a pair. Replacing just one tire can seriously affect
your vehicle’s handling. If you ever replace a wheel, make
sure that the wheel’s specifications match those of the orig
-
inal wheels.
It is recommended you contact an authorized tire dealer or
original equipment dealer with any questions you may have
on tire specifications or capability. Failure to use equivalent
replacement tires may adversely affect the safety, handling,
and ride of your vehicle.
WARNING!
• Do not use a tire, wheel size, load rating, or speed rating other than that specified for your vehicle. Some combi -
nations of unapproved tires and wheels may change
suspension dimensions and performance characteris -
tics, resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpredictable
handling and stress to steering and suspension compo -
nents. You could lose control and have a collision
resulting in serious injury or death. Use only the tire
and wheel sizes with load ratings approved for your
vehicle.
