Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers — especially children — can
easily open the doors and fall out of a
moving vehicle. When a door is locked it
will not open. You increase the chance of
being thrown out of the vehicle in a crash
if the doors are not locked. So, wear safety
belts properly and lock the doors
whenever you drive.
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.There are several ways to lock and unlock your vehicle.
From the outside, press the lock or unlock button on
the keyless access transmitter. When you have
the transmitter with you, you may also unlock and open
the door by squeezing the door handle sensor. You
do not have to press the unlock button on the
transmitter. You will be able to open the door when you
press the door handle sensor and the vehicle
recognizes your keyless access transmitter. When the
passenger door is opened rst, the driver’s door will
also unlock.
From the inside, use the power door lock switch located
at the top of the door panel near both windows. See
Power Door Locks on page 2-12.

Arming the System
Use one of the three following items listed here to arm
the system:
Press the lock button on the keyless access
transmitter.
Open the door. Lock the door with the power door
lock switch. The security light should ash.
Remove the keyless access transmitter from inside
the vehicle and close the door. The security light
will stop ashing and stay on. After 30 seconds, the
light should turn off.
The vehicle can be programmed to automatically
lock the doors and arm the theft-deterrent system
when you exit the vehicle. SeeDIC Vehicle
Personalization on page 3-69.
Now, if a door or the trunk lid is opened without the
keyless access transmitter, the alarm will go off. Your
horn will sound for two minutes, then it will go off to save
battery power. Your vehicle will not start without a
keyless transmitter present.
The theft-deterrent system will not arm if you lock the
driver’s door with the power door lock switch after
the doors are closed.
If your passenger stays in the vehicle when you leave
with the keyless access transmitter, have the passenger
lock the vehicle after the doors are closed. This way the
alarm will not arm, and your passenger will not set it off.
Testing the Alarm
Do the following to test the system:
1. Make sure the trunk lid is latched.
2. Lower the window on the driver’s door.
3. Manually arm the system.
4. Close the doors and wait 30 seconds.
5. Reach through the open window and manually pull
the release lever on the oor.
6. Turn off the alarm by pressing the unlock button on
the transmitter.
If the alarm is inoperative, check to see if the horn
works. If not, check the horn fuse. SeeFuses and Circuit
Breakers on page 5-85. If the horn works, but the
alarm doesn’t go off, see your dealer.
Disarming the System
Always use your keyless access transmitter to unlock a
door either by pressing the unlock button on the
transmitter or by squeezing the door handle sensor
while you have the transmitter with you. Unlocking a
door any other way will set off the alarm. If your alarm
sounds, press the unlock button on the keyless
access transmitter to disarm it.

Twilight Sentinel®
Twilight Sentinel®can turn your lamps on and off for
you. A light sensor on top of the instrument panel makes
the Twilight Sentinel
®work, so be sure it is not
covered.
With Twilight Sentinel
®, you will see the following
happen:
When it is dark enough outside, the front turn signal
lamps (DRL) will go off, and the headlamps and
parking lamps will come on. The other lamps
that come on with headlamps will also come on.
When it is bright enough outside, the headlamps
will go off, and the front turn signal lamps (DRL)
will come on, as long as the exterior lamp switch is
in the AUTO position.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once
you leave the garage, it will take about one minute for
the automatic headlamp system to change to DRL if it is
light outside. During that delay, your instrument panel
cluster may not be as bright as usual. Make sure
your instrument panel brightness control is in full bright
position. SeeInstrument Panel Brightness on
page 3-19.You can idle the vehicle with the lamps off, even when
it is dark outside.
After starting the vehicle, turn the exterior lamp control
band on the multifunction lever to off and then
release it. The lamps will remain off until you turn the
control band to off again.
Twilight Sentinel
®also provides exterior illumination as
you leave the vehicle. If Twilight Sentinel®has turned
on the lamps when you turn off the ignition, your lamps
will remain on until:
The exterior lamp switch is moved from off to the
parking lamp position, or
a delay time that you select has elapsed.
See “Personal Options” underDIC Vehicle
Personalization on page 3-69to select the delay time
that you want. You can also select no delay time.
If you turn off the ignition with the exterior lamp switch
in the parking lamp or headlamp position, the Twilight
Sentinel
®delay will not occur. The lamps will turn off as
soon as the switch is turned off.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Automatic Operation
AUTO (Automatic):Press the AUTO button to place
the entire system in the automatic mode. When
automatic operation is active, the system will
automatically control the inside temperature, the air
delivery mode and the fan speed.
After a ten second display of the current settings, the
word AUTO, the driver’s temperature setting and
the outside temperature will be shown. The system will
operate to achieve your comfort set temperature as
quickly as possible. The AUTO control system works
best with the windows up and the removable roof
installed or the convertible top up.1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting
between 60°F (16°C) and 90°F (32°C). Choosing
the coldest or warmest temperature setting will
not cause the system to heat or cool any faster.
A setting of 73°F (23°C) is suggested.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will
start out blowing air at the oor but may change
modes automatically as the vehicle warms up
to maintain the chosen temperature setting. The
length of time needed for warm up will depend on
the outside temperature and the length of time
that has elapsed since your vehicle was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature, if
necessary.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensor” later in
this section.
3-26

Sensors
The solar sensor on your vehicle monitors the solar
radiation and uses the information to maintain the
selected temperature when operating in AUTO mode by
initiating needed adjustments to the temperature, the
fan speed and the air delivery system. The system may
also supply cooler air to the side of the vehicle facing
the sun. The recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located on
the top of the instrument panel near the windshield
or the system will not work properly.
There is also a sensor located behind the front bumper.
This sensor reads the outside air temperature and
helps to maintain the temperature inside the vehicle.
Any cover on the front of the vehicle could give a false
reading in the temperature.
If the outside temperature goes up, the displayed
temperature will not change until:
The vehicle’s speed is above 10 mph (16 km/h)
ve minutes.
The vehicle’s speed is above 32 mph (52 km/h) for
two and a half minutes.
These delays prevent false readings. If the temperature
goes down, the outside temperature will be shown
when you start the vehicle. If it has been turned off for
less than three hours, the temperature will be recalled
from the previous vehicle operation.There is also an inside temperature sensor located to
the left of the ignition switch. The automatic climate
control system uses this sensor to receive information,
so if you block or cover it, the system will not function
properly.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
and moisture condensing on the cool window glass.
This can be minimized if the climate control system is
used properly. There are two modes to clear fog or frost
from your windshield. Use the oor/defog mode to
clear the windows of fog or moisture and warm
the passengers. Use defrost to remove fog or frost from
the windshield more quickly. To prevent fogging on
the inside of the windows in modes other than
oor/defog and defrost, make sure the air conditioning
compressor is on and recirculation mode is off.
Press the mode button until the defog mode appears on
the display.
-(Floor/Defog):This mode directs the air equally
between the windshield and the oor outlets with a small
amount to the side window outlets. When you select
this mode, the system turns off recirculation and runs the
air-conditioning compressor unless the outside
temperature is at or below freezing. The recirculation
mode cannot be selected while in the defog mode.
