Driving
AUTOMATIC TRANSMISSION OPERATION (IF EQUIPPED)

Brake-shift interlock

This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the 3 (ON) position and the brake pedal is not depressed.
If you cannot move the gearshift lever out of the P (Park) position with
the ignition in the 3 (ON) position and the brake pedal depressed:
1. Apply the parking brake. Turn the
ignition key to 1 (OFF/LOCK), then
remove the key. Locate the access
cover plate for the brake-shift
interlock override. It is located on
top of the steering column shroud.
2. Apply the brake. Use a tool (or a
small screwdriver) to pry out the
access cover. Insert the tool into the
access hole and slide the white
override button towards the left.
Move the gear shift lever into N
(Neutral) while holding the white
override disc towards the left.
When the key is in the ignition and in the OFF position, the
automatic transmission shift lever can be moved from the P
(Park) position without the brake pedal depressed. To avoid unwanted
vehicle movement, always set the parking brake.
3. Start the vehicle.
If it is necessary to use the above procedure to move the gearshift lever,
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.
Do not drive your vehicle until you verify that the brakelamps
are working.
