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 ON position unless brake pedal is depressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the ON position and the brake pedal depressed:
1. Apply the parking brake, turn ignition key to LOCK, then remove the
key.
2. Insert the key and turn it to OFF.Apply the brake pedal and shift
to N (Neutral).
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 toFuses and relaysin theRoadside
Emergencieschapter.
Do not drive your vehicle until you verify that the brakelamps
are working.
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.
If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your dealer or a qualified service technician.

FUSES AND RELAYS
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.
