²Optional instrument cluster
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level or mixture, the
gauge indication will not be accurate.
Battery voltage gauge (if equipped)
This gauge shows the battery
voltage when the ignition is in the
ON position. If the pointer moves
and stays outside the normal
operating range (as indicated), have
the vehicle's electrical system
checked as soon as possible.
Engine oil pressure gauge (if equipped)
This shows the engine oil pressure
in the system. Sufficient pressure
exists as long as the needle remains
in the normal range (the area
between the ªHº and ªLº).
If the gauge indicates low pressure,
stop the vehicle as soon as safely
possible and switch off the engine
immediately. Check the oil level.

Low washer fluid
Momentarily illuminates when the
ignition is turned to ON and will
stay on when the windshield washer
fluid is low.
Trunk ajar
If the trunk is not completely
closed, this light comes on when
you turn the ignition to ON. With
the ignition ON, this light will flash
five times and sound a tone for one
second, then remain on (if the trunk

Momentarily illuminates when the
ignition is turned to the ON position
and the engine is off. If brake
warning lamp does not illuminate at
this time, seek service immediately.
Also illuminates when the parking brake is engaged. Illumination after
releasing the parking brake indicates low brake fluid level and the brake
system should be inspected immediately.

time after the ignition switch is
turned to OFF.
²To turn autolamps on, rotate the
control counterclockwise. The preselected time lapse is adjustable up
to approximately three minutes by continuing to rotate the control
counterclockwise.
²To turn autolamps off, rotate the control clockwise to OFF.
²A small LED illuminates under the autolamp control to indicate that
the headlamps have been turned on by the autolamps.
Daytime running lamps (DRL) (if equipped)
Turns the highbeam headlamps on with a reduced output. To activate:
²the engine must be running,
²the parking brake released, and
²the headlamp control is in the OFF or Parking lamps position.
The Daytime Running Light (DRL) system will not illuminate the
tail lamps and parking lamps. Turn on your headlamps at dusk.
Failure to do so may result in a collision.

Turning the EATC on
Press AUTOMATIC, any of the
override controls or the fan speed
control. The EATC will only operate
when the ignition is in the ON
position.
Turning the EATC off
Press OFF. The Outside
Temperature function will continue
to operate until the ignition is
turned off.
Automatic operation
Press AUTOMATIC and select the desired temperature. The selected
temperature and the word AUTO will appear in the display window. The
EATC system will either heat or cool to achieve the selected
temperature. The system will automatically determine fan speed, airflow
location and if fresh outside air or recirculated air is required. Fan speed
remains automatic unless the fan speed thumbwheel is turned.
When in AUTOMATIC and weather conditions require heat, air will be
sent to the floor. However, if the engine is not warm enough to provide
heat, the fan will be at a low speed and the air will be directed to the
windshield. In 3ó minutes or less, the fan speed will start to increase
and the airflow location will change to the floor area.
If unusual conditions exist (i.e.-window fogging, etc.), the manual
override controls allow you to select airflow locations and the fan control
allows you to adjust fan speed as necessary.

Replacing lost transmitters
Take all your vehicle's transmitters
to your dealer for reprogramming if:
²a transmitter is lost or
²you want to purchase additional
transmitters (up to four may be
programmed).
SECURILOCKYANTI-THEFT SYSTEM
The SecuriLockyanti-theft system provides an advanced level of vehicle
theft protection. Your vehicle's engine can only be started with the two
special SecuriLockyelectronically coded keys provided with your
vehicle. Each time you start your vehicle, the SecuriLockykey is read
by the SecuriLockyanti-theft system. If the SecuriLockykey
identification code matches the code stored in the SecuriLocky
anti-theft system, the vehicle's engine is allowed to start. If the
SecuriLockykey identification code does not match the code stored in
the system or if a SecuriLockykey is not detected (vehicle theft
situation), the vehicle's engine will not operate.
Spare SecuriLockykeys can be purchased from your dealership and
programmed to your SecuriLockyanti-theft system. Refer to
Programming spare SecuriLockykeysfor more information.
If one or both of your SecuriLockykeys are lost or stolen and you want
to ensure the lost or stolen key will not operate your vehicle, bring your
vehicle and all available SecuriLockykeys to your dealership for
reinitialization.
Theft indicator
The theft indicator on top of the instrument panel will operate as follows:
²When the ignition is OFF, the theft indicator will flash briefly every
2 seconds to indicate the SecuriLockysystem is protecting your
vehicle.
²When the ignition is turned to RUN or START, the theft indicator will
light for 3 seconds and then go out. If the theft indicator stays on for
an extended period of time or flashes rapidly, have the system
serviced by your dealership or a qualified technician.

Programming spare SecuriLockYkeys
Spare SecuriLockykeys can be purchased from your dealership and
programmed to your SecuriLockyanti-theft system (up to a total of
8 keys). Your dealership can program your new SecuriLockykey(s) to
your vehicle or you can do it yourself using the following simple
procedure. To program a new SecuriLockykey yourself, you will need
two previously programmed SecuriLockykeys (keys that already
operate your vehicle's engine). If two previously programmed
SecuriLockykeys are not available (one or both of your original keys
were lost or stolen), you must bring your vehicle to your dealership to
have the spare SecuriLockykey(s) programmed.
Procedure to program spare SecuriLockYkeys to your vehicle
New SecuriLockykeys must have the correct mechanical key cut for
your vehicle.
Conventional (non-SecuriLocky) keyscannotbe programmed to your
vehicle.
You will need to have two previously programmed SecuriLockykeys and
the new unprogrammed SecuriLockykey readily accessible for timely
implementation of each step in the procedure. Please read and
understand the entire procedure before you begin.
1. Insert the first previously programmed SecuriLockykey into the
ignition and turn the ignition from OFF to RUN (maintain ignition in
RUN for at least one second).
2. Turn ignition to OFF and remove the first SecuriLockykey from the
ignition.
3. Within five seconds of turning the ignition to OFF, insert the second
previously programmed SecuriLockykey into the ignition and turn the
ignition from OFF to RUN (maintain ignition in RUN for at least one
second but no more than 5 seconds).
4. Turn the ignition to OFF and remove the second SecuriLockykey
from the ignition.
5. Within 10 seconds of turning the ignition to OFF, insert the
unprogrammed SecuriLockykey (new key) into the ignition and turn
the ignition from OFF to RUN (maintain ignition in RUN for at least one
second). This step will program your new SecuriLockykey.
6. If it is desired to program additional SecuriLockykey(s), repeat this
procedure from step 1.
