Brake-Shift Interlock
WARNINGS
Do not drive your vehicle until you
verify that the brake lamps are working.
When doing this procedure, you need
to take the transmission out of park (P)
which means your vehicle can roll freely. To
avoid unwanted vehicle movement, always
fully set the parking brake prior to doing this
procedure. Use wheels chocks if appropriate.

If you cannot move the gearshift lever out of

position and the brake pedal pressed, a
malfunction may have occurred. It is possible
that a fuse has blown or your vehicle's brake
lamps are not operating properly. See Fuse
Specification Chart (page 243).

are working properly, the following
procedure will allow you to move the
gearshift lever from park (P):
1. Apply the parking brake. Turn the ignition
key to the off position, then remove the
key.
