Transmission Limp Home Mode
Transmission function is monitored for abnor-
mal conditions. If a condition is detected that
could result in transmission damage, the Trans-
mission Limp Home Mode will be engaged. In
this mode, the transmission will operate (when

To reset the transmission, use the following
procedure:
1. Stop the vehicle.
2. Move the shift lever to the PARK position.
3. Turn OFF the engine and be sure to turn the
key fob to the LOCK position.
4. Wait approximately 10 seconds, then restart
the engine.
5. Move the shift lever to the desired gear
range.
If the problem is no longer detected, the trans-
mission will return to normal operation. If the
problem persists, PARK, REVERSE, and NEU-
TRAL will continue to operate. Only second
gear will operate in the DRIVE position. Have

the transmission checked at your authorized
dealer as soon as possible.
Torque Converter Clutch
A feature designed to improve fuel economy
has been added to the automatic transmission
of this vehicle. A clutch within the torque con-
verter engages automatically at calibrated
speeds. This may result in a slightly different
feeling or response during normal operation in
high gear. When the vehicle speed drops or
during acceleration, the clutch automatically
and smoothly disengages.

and not intended for normal driving. Driving in
