Brake-shift interlock
WARNING:To prevent vehicle movement when following this
procedure, park on a level surface, ensure parking brake is set,
and block the rear wheels.
WARNING:If your brake lamps are not working properly or if
you have disconnected the vehicle battery cables, the vehicle
brake lamps and hazard flashers may not properly warn traffic of a
vehicle breakdown or approaching danger, which can increase the risk
of serious injury or death. To minimize the risk of serious injury or
death, be aware of your surroundings, use other hazard signaling
devices if available, and move the vehicle to a safe location away from
traffic as soon as possible.
WARNING:Do not drive your vehicle until you verify that the
brake lamps 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.
WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer.
The vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) unless the brake
pedal is pressed.
If you cannot move the gearshift lever out of P (Park) position with the
ignition in the 4 (on) position and the brake pedal pressed, a
malfunction may have occurred. It is possible that a fuse has blown or
the vehicle’s brake lamps are not operating properly. Refer toFuses and
relaysin theRoadside Emergencieschapter. If the fuses and brake
lamps are working properly, and the vehicle still will not shift out of (P)
Park, see your authorized dealer for service.

CHANGING A FUSE
Fuses
If electrical components in the vehicle
are not working, a fuse may have
blown. Blown fuses are identified by a
broken wire within the fuse. Check
the appropriate fuses before replacing
any electrical components.
Note:Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.
