Then, without shutting off the engine, follow
these steps:
1. Pull out the dipstick and wipe it with a clean
rag or paper towel.
The automatic transaxle dipstick is located
toward the back of the engine compartment,
near the brake master cylinder reservoir.
The dipstick handle is a red loop. See Engine
Compartment Overview on page 420 for
more information on location.
2. Push it back in all the way, wait three seconds,
and then pull it back out again.
3. Check both sides of the dipstick, and read
the lower level. The fluid level must be in
the cross-hatched area.
4. If the fluid level is in the acceptable range,
push the dipstick back in all the way.
How to Add Automatic Transaxle Fluid
Refer to the Maintenance Schedule to
determine what kind of transaxle fluid to use. See
Recommended Fluids and Lubricants on page 530.
If the fluid level is low, add only enough of the
proper fluid to bring the level into the cross-hatched
area on the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at
the dipstick hole to bring it to the proper level.
It does not take much fluid, generally less
than one pint (0.5 L). Do not overfill.
Notice: Use of the incorrect automatic
transaxle fluid may damage your vehicle, and
the damages may not be covered by your
warranty. Always use the automatic transaxle
fluid listed in Recommended Fluids and
Lubricants on page 530.
3. After adding fluid, recheck the fluid level as
described under "How to Check Automatic
Transaxle Fluid," earlier in this section.
4. When the correct fluid level is obtained, push
the dipstick back in all the way.
