How to Reset Transaxle Fluid
Change Indicator
Your vehicle is equipped with a transaxle fluid change
indicator. A CHANGE TRANS FLUID message will
display on the Driver Information Center (DIC) when
the powertrain computer determines that the transaxle
fluid needs to be changed or at each 100,000 miles
(160 000 km) interval, whichever occurs first. See your
Maintenance Schedule booklet for more information.
When this message appears, change the transaxle fluid
and reset the transaxle fluid life indicator as follows:
1. Turn the ignition on but do not start the engine.
2. Press and hold the OFF and rear defog buttons on the
climate control system at the same time until the
TRANS FLUID RESET message appears on the DIC.
