Checking Oil Level
To ensure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. The
engine oil level should be checked five minutes after a
warmed up engine has been 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 (0.95 liters) 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.
CAUTION!
Overfilling or underfilling the crankcase will cause
aeration or loss of oil pressure. This could damage your
engine.
Adding Washer Fluid
The fluid reservoir for the windshield washers and the rear
window washer (if equipped) 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 refillingthe 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.
WARNING!
Commercial windshield washer solvents are flam-
mable. They could ignite and burn you. Care must be
exercised when filling or working around the washer
solution.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic mainte-
nance required.
378 SERVICING AND MAINTENANCE

WARNING!
•Use only refrigerants and compressor lubricants ap-
proved by the manufacturer for your air conditioning
system. Some unapproved refrigerants are flam-
mable and can explode, injuring you. Other unap-
proved refrigerants or lubricants can cause the sys-
tem to fail, requiring costly repairs. Refer to
Warranty Information Book, located in your owner ’s
information kit, for further warranty information.
• The air conditioning system contains refrigerant un-
der 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 condition-
ing components. Such damage is not covered by the
New Vehicle Limited Warranty.
Refrigerant Recovery And Recycling R134a —
If Equipped
R-134a Air Conditioning Refrigerant is a hydrofluoro-
carbon (HFC) that is an ozone-friendly substance. The
manufacturer recommends that air conditioning service be
performed by an authorized dealer or other service facili-
ties 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
authorized dealer using recovery and recycling equipment.
NOTE: Use only manufacturer approved A/C system
PAG compressor oil, and refrigerants.
386 SERVICING AND MAINTENANCE

WARNING!(Continued)
•To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der reservoir cap secured at all times. Brake fluid in
a open container absorbs moisture from the air
resulting in a lower boiling point. This may cause it
to boil unexpectedly during hard or prolonged brak-
ing, resulting in sudden brake failure. This could
result in a collision.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.
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. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for further information.
Fluid Level Check
Lubricant should be at the bottom edge of the oil fill hole.
Adding Fluid
Add lubricant only at the fill hole and only to the level
specified above.
Selection Of Lubricant
Use only the manufacturer’s recommended fluid. Refer to
“Fluids And Lubricants” in “Technical Specifications” for
further information.

5. Place the gear selector momentarily into each gearposition (allowing time for the transmission to fully
engage in each position), ending with the transmission
in PARK.
6. Remove the dipstick, wipe it clean and reinsert 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
under “Technical 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:
•The holes in the dipstick will be full of fluid if the
actual level is at or above the hole.
• If it is necessary to check the transmission below the
operating temperature, the fluid level should be be-
tween the two COLD (lower) holes on the dipstick
with the fluid at approximately 80°F (27°C). If the fluid
level is correctly established at 80° F (27°C), it should
be between the HOT (upper) reference holes when the
transmission reaches 180° F (82°C). Remember it is best
to check the level at the 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.
8. Reinstall the engine cover and snap it down securely onto the four mounting studs.
9. Check for leaks. Release the parking brake.
