CAUTION!(Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage your engine,
transmission, power steering or air conditioning.
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 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 1.0 quart (.95
liters) 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.

test. Drive belt tension should also be checked at this
time.
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.
CAUTION!
Do not use chemical flushes in your air conditioning
system as the chemicals can damage your air condi-
tioning 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 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
PAG compressor oil and refrigerants.
