■If the shift lever cannot be shifted from P
First, check whether the brake pedal is being depressed.
If the shift lever cannot be shifted even though the brake peda l is depressed

The following steps may be used as an emergency measure to ensu re that
the shift lever can be shifted.
Releasing the shift lock:
Set the parking brake.
Turn the engine switch off.
Depress the brake pedal.
■ If the S indicator does not come on or the D indicator is displayed even
after shifting the shift lever to S
