Speed sensitive steering
The steering in your vehicle is speed sensitive. At high speeds, steering
assist will decrease to improve steering feel. At lower speeds,
maneuverability will be increased.
If the amount of effort required to steer your vehicle changes while
driving at a constant vehicle speed, have the power steering system
checked by your dealer or a qualified service technician.
AUTOMATIC TRANSMISSION OPERATION
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 RUN position unless brake pedal is depressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the RUN 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 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.

may have been activated.
This switch is located in the driver’s
footwell, behind the kick panel.
To reset the switch:
1. Turn the ignition OFF.
2. Check the fuel system for leaks.
3. If no leaks are apparent, reset the
switch by pushing in on the reset
button.
4. Turn the ignition ON.
5. Wait a few seconds and return
the key to OFF.
6. Make another check for leaks.
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.

Rear power distribution box
The rear power distribution box is
located in the luggage compartment
under the spare tire well cover. The
power distribution box contains
high-current fuses that protect your
vehicle’s main electrical systems
from overloads.
Always disconnect the battery before servicing high current
fuses.
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.
The high-current fuses are coded as follows.
