SOURCE: Press this button to play a CD if you have a
magazine loaded in the changer and the radio is playing.

Personal Choice Radio Controls
(If Equipped)
With this feature, your vehicle will recall the latest radio
settings as adjusted the last time your vehicle was
operated. This feature allows two different drivers to
store and recall their own radio settings for AM and FM
presets, last tuned station, volume, tone and audio
source (radio, cassette or CD). The settings recalled by
the radio are determined by which transmitter (ª1º or
ª2º) was used to enter the vehicle. The number on the
back of the transmitter corresponds to driver 1 or to
driver 2. After the UNLOCK button is pressed on the
transmitter and the ignition is in RUN, the radio settings
will automatically adjust to where they were last set by
the identified driver. The settings can also be changed by
pressing one of the MEMORY buttons (1 or 2) located
on the driver's door until you hear two beeps. When
changes are made, the new settings will be saved for
the driver.
Theft-Deterrent Feature
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 indicator
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.
Activating the Theft
-Deterrent Feature
The instructions which follow explain how to enter your
secret code to activate the THEFTLOCK system. It is
recommended that you read through all nine steps
before starting the procedure.

If you drive regularly in steep country, or if you're
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.

Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system
and transaxle. These parts can work hard on
mountain roads.

Know how to go down hills. The most important
thing to know is this: let your engine do some of the
slowing down. Shift to a lower gear when you go
down a steep or long hill.
CAUTION:
If you don't shift down, your brakes 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. Shift down to let your
engine assist your brakes on a steep
downhill slope.
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. Drive in the highest
gear possible.

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.

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.
Put an automatic transaxle in PARK (P) before
setting the parking brake.
3. Turn off the ignition on both vehicles. Turn off the
radios and all lamps that aren't needed. This will
avoid sparks and help save both batteries. It could
save your radio!
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
4. Open the hood and locate the batteries.
CAUTION:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.
5. Find the positive (+) and negative (-) terminals on
each battery.

When the TIRE PRESSURE LOW: CHECK TIRES
message appears on the Driver Information Center, you
should stop as soon as you can and check all your tires for
damage. (If a tire is flat, see ªIf a Tire Goes Flatº in the
Index.) Also check the tire pressure in all four tires as soon
as you can. See ªInflation
-Tire Pressureº in the Index.
Any time you adjust a tire's pressure or have one or
more tires repaired or replaced, you'll need to reset
(calibrate) the check tire pressure system. You'll also
need to reset the system whenever you rotate the tires,
buy new tires, install or remove the compact spare, and
whenever the vehicle's battery has been disconnected.
Don't reset the check tire pressure system without first
correcting the cause of the problem and checking and
adjusting the pressure in all four tires. If you reset the
system when the tire pressures are incorrect, the check
tire pressure system will not work properly and may not
alert you when a tire is low or high.To reset (calibrate) the system:
1. Turn the ignition switch to RUN.
2. Press the GAGE INFO button on the DIC until
TIRE PRESSURE appears on the display.
3. Press and hold the DIC RESET button for about five
seconds. After five seconds, the display will show
TIRE PRESSURE RESET. If TIRE PRESSURE
RESET does not appear on the display after about
five seconds, see your dealer for service. After you
release the DIC RESET button, TIRE PRESSURE
NORMAL will appear on the display.
The system completes the calibration process during
driving. During the first 10 to 25 miles (15 to 40 km) of
driving, the system will not alert you if a tire is high or
low. After 25 to 100 miles (40 to 160 km), the
system will only alert you about pressure differences of
12 psi (85 kPa) or more. After about 100 miles (160 km)
of driving, the system will alert you if one tire is
10 psi (69 kPa) different from the other three tires.

Ignition Transaxle Lock Check
While parked, and with the parking brake set, try to turn
the ignition key to LOCK in each shift lever position.

The key should turn to LOCK only when the shift
lever is in PARK (P).

The key should come out only in LOCK.
Parking Brake and Automatic Transaxle PARK (P)
Mechanism Check
CAUTION:
When you are doing this check, your vehicle
could begin to move. You or others could be
injured and property could be damaged. Make
sure there is room in front of your vehicle in case
it begins to roll. Be ready to apply the regular
brake at once should the vehicle begin to move.
Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot on the regular brake, set the
parking brake.
To check the parking brake's holding ability: With
the engine running and transaxle in NEUTRAL (N),
slowly remove foot pressure from the regular brake
pedal. Do this until the vehicle is held by the parking
brake only.

To check the PARK (P) mechanism's holding ability:
With the engine running, shift to PARK (P). Then
release all brakes.
Underbody Flushing Service
At least every spring, use plain water to flush any
corrosive materials from the underbody. Take care to
clean thoroughly any areas where mud and other debris
can collect.
