{ CAUTION:
Operating the engine with the air cleaner/filter off
can cause you or others to be burned. The air
cleaner not only cleans the air; it helps to stop
flames if the engine backfires. If it is not there and
the engine backfires, you could be burned. Do not
drive with it off, and be careful working on the
engine with the air cleaner/filter off.
Automatic Transmission Fluid
When to Check and Change Automatic
Transmission Fluid
It is usually not necessary to check the transmission
fluid level. The only reason for fluid loss is a
transmission leak or overheating the transmission. If
you suspect a small leak, then use the following
checking procedures to check the fluid level. However,
if there is a large leak, then it may be necessary to
have the vehicle towed to a dealer/retailer service
department and have it repaired before driving the
vehicle further.
Notice: Use of the incorrect automatic transmission
fluid may damage the vehicle, and the damages
may not be covered by the vehicle’s warranty.
Always use the automatic transmission fluid listed
in Recommended Fluids and Lubricants on
page 6-13.
Change the fluid and filter at the intervals listed in the
Maintenance Schedule. See Scheduled Maintenance on
page 6-4. Be sure to use the transmission fluid listed
in Recommended Fluids and Lubricants on page 6-13.
How to Check Automatic Transmission
Fluid
Notice: Too much or too little fluid can damage
your transmission. Too much can mean that some
of the fluid could come out and fall on hot engine
parts or exhaust system parts, starting a fire.
Too little fluid could cause the transmission to
overheat. Be sure to get an accurate reading if you
check your transmission fluid.
Before checking the fluid level, prepare the vehicle as
follows:
1. Start the engine and park the vehicle on a level
surface. Keep the engine running.
2. Apply the parking brake and place the shift lever in
P (Park).
