(d) Starting the engine after a
battery discharge
With smart key system only—
In the event that the battery is dis-
charged, the engine may not restart
even after the battery is recharged or
replaced. For safety reasons, the engine
may be disabled when battery voltage
is extremely low. If the engine is dis-
abled, it must be normalized before it
can be restarted.
To normalize the start system:
1. Shift the transmission to the "P" posi-
tion and set the ignition switch off.
2. Open and close any of the doors.
3. Start the engine.
