Press the service brake pedal with
your foot and pull the parking brake
release handle to release the
parking brake.
Brake over accelerator
This vehicle is equipped with a brake over accelerator feature. In the
event the accelerator pedal becomes stuck or entrapped, applying steady
and firm pressure to the brake pedal will both slow the vehicle and
reduce engine power. If you experience this condition, apply the brakes
and bring your vehicle to a safe stop. Turn the engine off, shift to P
(Park) and apply the parking brake, and then inspect the accelerator
pedal for any interferences. If none are found and the condition persists,
have your vehicle towed to the nearest authorized dealer.
AUTOMATIC TRANSMISSION OPERATION
Brake-shift interlock
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.

Power distribution box
The power distribution box is located in the engine compartment. The
power distribution box contains high-current fuses that protect your
vehicle’s main electrical systems from overloads.
WARNING:Always disconnect the battery before servicing high
current fuses.
WARNING:To reduce risk of electrical shock, always replace
the cover to the power distribution box before reconnecting the
battery or refilling fluid reservoirs.
If the battery has been disconnected and reconnected, refer to the
Batterysection of theMaintenance and Specificationschapter.
