3-27 Theft-Deterrent Feature (If Equipped)
THEFTLOCK
is designed to discourage theft of your
radio. It works by using a secret code to disable all radio
functions whenever battery power is removed.
If THEFTLOCK is active, the THEFTLOCK will flash
when the ignition is off.
The THEFTLOCK feature for the radio may be used or
ignored. If ignored, the system plays normally and the
radio is not protected by the feature. If THEFTLOCK is
activated, your radio will not operate if stolen.
When THEFTLOCK is activated, the radio will display
LOC to indicate a locked condition anytime battery
power is removed. If your battery loses power for any
reason, you must unlock the radio with the secret code
before it will operate.

your secret code to activate the THEFTLOCK system.
It is recommended that you read through all nine steps
before starting the procedure.If you allow more than 15 seconds to elapse between

CAUTION:
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. Your brakes will have to
do all the work of slowing down. They could get
so hot that they wouldn't work well. You would
then have poor braking or even none going
down a hill. You could crash. Always have your
engine running and your vehicle in gear when
you go downhill.

Know how to go uphill. You may want to shift
down to a lower gear. The lower gears help cool
your engine and transaxle, and you can climb the
hill better.

Stay in your own lane when driving on two
-lane
roads in hills or mountains. Don't swing wide or cut
across the center of the road. Drive at speeds that let
you stay in your own lane.

As you go over the top of a hill, be alert. There
could be something in your lane, like a stalled
car or an accident.

You may see highway signs on mountains that
warn of special problems. Examples are long grades,
passing or no
-passing zones, a falling rocks area
or winding roads. Be alert to these and take
appropriate action.

4-31 Dolly Towing
To dolly tow your vehicle, do the following:
1. Put the front or rear wheels on a dolly.
2. Put the vehicle in PARK (P).
3. Set the parking brake and then remove the key from
the ignition.
4. Clamp the steering wheel in a straight
-ahead position
with a clamping device designed for towing.
5. Release the parking brake.
Loading Your Vehicle
Two labels on your vehicle show how much weight it
may properly carry. The Tire
-Loading Information label
is inside the trunk lid. The label tells you the proper size,
speed rating and recommended inflation pressures for
the tires on your vehicle. It also gives you important
information about the number of people that can be in
your vehicle and the total weight you can carry. This
weight is called the vehicle capacity weight and includes
the weight of all occupants, cargo and all
nonfactory
-installed options.

5-4
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren't touching
each other. If they are, it could cause a ground
connection you don't want. You wouldn't be able
to start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set the
parking brake firmly on both vehicles involved in the
jump start procedure. Put an automatic transaxle in
PARK (P) before setting the parking brake.
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or in the auxiliary power outlet. Turn off the
radio and all lamps that aren't needed. This will
avoid sparks and help save both batteries. And it
could save your radio!
4. Open the hoods and locate the batteries. Find the
positive (+) and negative (
-) terminal location on
each vehicle. You will not need to access your
battery for jump starting. Your vehicle has a remote
positive (+) jump starting terminal for that purpose.
The terminal is located on the same side of the
engine compartment as your battery. See ªEngine
Compartment Overviewº in the Index for more
information on location.
