Lockout Protection
Lockout protection is intended to provide enhanced
security and convenience. This feature prevents a driver
who has left the keys in the ignition from locking the
doors, using the power door locks while any door
is open.
To override this feature, when the key is in the ignition
and any door is open, press and hold down the
power door lock switch for three seconds.
This feature cannot guarantee that you will never be
locked out of your vehicle.
If you don’t leave the keys in
the ignition, or
if you use the manual door lock or the
remote keyless entry transmitter, you could still lock your
keys inside your vehicle. Always remember to take
your keys with you.
Leaving Your Vehicle
If you are leaving your vehicle, open your door and
set the locks from the inside, then get out and close
the door.

Safety Belt Reminder Light
When the key is turned to ON or START, a chime will
come on for several seconds to remind people to fasten
their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will also come on and stay on
for several seconds,
then it will flash for
several more.
If the driver’s belt is already buckled, neither the chime
nor the light will come on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag’s electrical system for malfunctions.
The light tells you
if there is an electrical problem.
The system check includes the air bag modules, the
wiring and the crash sensing and diagnostic module. For
more information on the air bag system, see
Supplemental Restraint System (SRS) on page 1-53.
This light will come on
when you start your
vehicle, and it will flash for
a few seconds. Then

If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your dealer. The arrows on your instrument
panel will flash whenever you signal a turn or lane
change. Properly hooked up, the trailer lamps will also
flash, telling other drivers you’re about to turn,
change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will flash for turns even
if the bulbs on the trailer
are burned out. Thus, you may think drivers behind
you are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are stiil working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down, you might have to use your brakes
so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around
45 mph (70 km/h) to reduce the
possibility of engine and transaxle overheating.
P; ‘ting on Hills
You really should not park your vehicle, with a
trailer attached, on a hill.
If something goes
wrong, your rig could start to move. People
can be injured, and both your vehicle and the
trailer can be damaged.
But
if you ever have to park your rig on a hill, here’s
how to do it:
1. Apply your regular brakes, but don’t shift into
PARK (P) for an automatic transaxle or into a
gear for a manual transaxle, yet. When parking
uphill, turn your wheels away from the curb. When
parking downhill, turn your wheels into the curb.
2. Have someone place chocks under the trailer
1/:!?ee!s.
3. When the chocks are in place, release the regular
brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your
parking brake and shift into PARK (P) for an
automatic transaxle or
REVERSE (R) for a manual
transaxle.
5. Release the regular brakes.

Options
A circuit breaker in the fuse panel protects the power
windows. When the current load is too heavy, the circuit
breaker opens and closes, protecting the circuit until
the problem is fixed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination
of fuses, circuit breakers
and fusible links. This greatly reduces the chance of
damage caused by electrical problems.
There are three fuse blocks in your vehicle: two
instrument panel fuse blocks and the engine
compartment fuse block.
There are four spare fuses located in the driver’s side
instrument panel end cap for your use.
Instrument Panel Fuse Blocks
There are two fuse panels for your vehicle. One is
located on the driver’s side of the instrument panel and
the other is located on the passenger’s side.
