{ CAUTION:
Operating the engine with the air cleaner/?lter off
can cause you or others to be burned. The air
cleaner not only cleans the air; it helps to stop
?ames if the engine back?res. If it is not there and
the engine back?res, you could be burned. Do not
drive with it off, and be careful working on the
engine with the air cleaner/?lter off.
Notice: If the air cleaner/?lter is off, a back?re can
cause a damaging engine ?re. And, dirt can easily get
into the engine, which will damage it. Always have
the air cleaner/?lter in place when you are driving.
Automatic Transmission Fluid
When to Check and Change Automatic
Transmission Fluid
A good time to check the automatic transmission ?uid
level is when the engine oil is changed.
Change the ?uid and ?lter at the intervals listed in
Additional Required Services on page 6-6, and be sure
to use the transmission ?uid listed in Recommended
Fluids and Lubricants on page 6-11.
How to Check Automatic
Transmission Fluid
Because this operation can be a little difficult, you may
choose to have this done at the dealer/retailer service
department.
If adding it yourself, be sure to follow all the instructions
here, or there could be a false reading on the dipstick.
Notice: Too much or too little ?uid can damage
your transmission. Too much can mean that some
of the ?uid could come out and fall on hot engine
parts or exhaust system parts, starting a ?re.
Too little ?uid could cause the transmission to
overheat. Be sure to get an accurate reading if you
check your transmission ?uid.
Wait at least 30 minutes before checking the
transmission ?uid level if you have been driving:
? When outside temperatures are above 90F (32C).
? At high speed for quite a while.
? In heavy traffic ? especially in hot weather.
? While pulling a trailer.
To get the right reading, the ?uid should be at normal
operating temperature, which is 180F to 200F
(82C to 93C).
