check the engine oil level is about five minutes after a
fully warmed engine is shut off or before starting the
engine after it has sat overnight.
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 1.0 qt (1.0 L) 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.
CAUTION!
Overfilling or underfilling will cause oil aeration or
loss of oil pressure. This could damage your engine.
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 in-
tervals 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 SM or
SM/CF.
The manufacturer recommends the use of a full synthetic
SAE 0W-40 engine oil or equivalent.
CAUTION!
Do not use chemical flushes in your engine oil as the
chemicals can damage your engine. Such damage is
not covered by the New Vehicle Limited Warranty.

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
Warranty Information Book, located on the DVD,
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.
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 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, compressor
oil, and refrigerants.
A/C Air Filter
The filter is located in the fresh air inlet under the hood,
behind a removable panel in the cowl on the passenger
side of the vehicle, next to the windshield wipers. When
installing a new filter, ensure its proper orientation.

Windshield Wiper Blades
Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth and a
mild nonabrasive cleaner. This will remove accumula-
tions of salt or road film.
Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always use
washer fluid when using the wipers to remove salt or dirt
from a dry windshield.
Avoid using the wiper blades to remove frost or ice from
the windshield. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc.
NOTE:
Life expectancy of wiper blades varies depending
on geographical area and frequency of use. Poor perfor-
mance of blades may be present with chattering, marks,
water lines or wet spots. If any of these conditions are
present, clean the wiper blades or replace as necessary.
Adding Washer Fluid
The windshield washer fluid reservoir is located in the
front of the engine compartment. Be sure to check the
fluid level at regular intervals. Fill the reservoir with
windshield washer solvent (not radiator antifreeze) and
operate the system for a few seconds to flush out the
residual water.
When refilling the washer fluid reservoir, apply some
washer fluid 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.
The fluid reservoir will hold nearly 1 gal (4 L) of washer
fluid when the message “Low Washer Fluid” appears in the
Electronic Vehicle Information Center (EVIC) (if equipped).
