310 STARTING AND OPERATING
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the LOCK/OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
NOTE: Even if the transmission can be reset, it is
recommended that you visit your authorized dealer at
your earliest possible convenience. Your authorized
dealer has diagnostic equipment to determine if the
problem could recur.
If the transmission cannot be reset, dealer service is
required.
Overdrive Operation
The automatic transmission includes an electronically
controlled Overdrive (fourth gear). The transmission will
automatically shift into the Overdrive gear if the follow-
ing conditions are present:
• the shift lever is in the DRIVE position,
• the transmission fluid has reached an adequate tem-
perature,
• the engine coolant has reached an adequate tempera-
ture,
• vehicle speed is sufficiently high, and
• the driver is not heavily pressing the accelerator.
