Notice: If the air cleaner/filter is
off, a backfire can cause a
damaging engine fire. And, dirt
can easily get into your engine,
which will damage it. Always have
the air cleaner/filter in place
when you are driving.
Automatic Transmission
Fluid
It is not necessary to check the
transmission fluid level. A
transmission fluid leak is the only
reason for fluid loss. If a leak occurs,
take your vehicle to a dealer/retailer
and have it repaired as soon as
possible.
Change the fluid and filter at the
intervals listed in the Maintenance
Schedule. See Scheduled
Maintenance on page 11-4. Be sure
to use the transmission fluid
listed in Recommended Fluids and
Lubricants on page 11-12.
Notice: Use of the incorrect
automatic transmission fluid may
damage your vehicle, and the
damages may not be covered by
your warranty. Always use the
automatic transmission fluid
listed in Recommended Fluids
and Lubricants on page 11-12.
Engine Coolant
The cooling system in your vehicle is
filled with DEX-COOL
®
engine
coolant. This coolant is designed to
remain in your vehicle for five years
or 150,000 miles (240 000 km),
whichever occurs first, if you add
only DEX-COOL
®
extended life
coolant.
The following explains your cooling
system and how to add coolant
when it is low. If you have a problem
with engine overheating, see
Engine Overheating on page 9-16.
A 50/50 mixture of clean, drinkable
water and DEX-COOL
®
coolant will:
• Give freezing protection down
to −34°F (−37°C).
• Give boiling protection up to
265°F (129°C).
• Protect against rust and
corrosion.
• Help keep the proper engine
temperature.
• Let the warning lights and gages
work as they should.
Notice: Using coolant other than
DEX-COOL
®
can cause premature
engine, heater core, or radiator
corrosion. In addition, the engine
coolant may require changing
sooner, at the first maintenance
service after each 30,000 miles
(50 000 km) or 24 months,
whichever occurs first. Any
repairs would not be covered by
the vehicle warranty. Always
use DEX-COOL
®
(silicate-free)
coolant in the vehicle.
