Driving
If you cannot move the gearshift lever out of P (Park) position with the
ignition in the 4 (on) position and the brake pedal depressed, a
malfunction may have occurred. It is possible that a fuse has blown or
the vehicle's brakelamps are not operating properly. Refer to Fuses and
relays in the Roadside Emergencies chapter. If the fuses and
brakelamps are working properly, and the vehicle still will not shift out of
(P) Park, see your authorized dealer for service.
If the fuse is not blown, perform the following procedure:
1. Apply the parking brake, and turn the ignition to the 4 (on) position.
2. Remove the lower trim panel under the steering column. Make sure
not disturb the wires on the electrical connector.
3. Locate the BSI solenoid
underneath the steering column.
4. With your hand, pull back on the
solenoid, and at the same time, shift
the transmission into N (Neutral).
5. Start the vehicle.
See your authorized dealer for service immediately.
WARNING: Do not drive your vehicle until you verify that the
brakelamps are working.
WARNING: Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Turn the ignition to the lock
position and remove the key whenever you leave your vehicle.
