How to Check
Because this operation can be a little difficult,
you may choose to have this done at the dealership
service department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading on the dipstick.
NOTICE:
Too much or too little fluid can damage your
transaxle. 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 transaxle to overheat. Be
sure to get an accurate reading if you check your
transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level if you have been driving:
D When outside temperatures are above 90_F (32_C).
D At high speed for quite a while.
D In heavy traffic
-- especially in hot weather.
D While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is 180
_F to 200_F
(82
_C to 93_C).
Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above 50
_F
(10
_C). If it’s colder than 50_F (10_C), you may
have to drive longer.
