When it is bright enough outside, the regular lamps
go off, and the front turn signal lamps will take over.
If the vehicle is started in a dark garage, the automatic
headlamp system comes on immediately. Once the
vehicle leaves the garage, it takes approximately
one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
the instrument panel cluster may not be as bright as
usual. Make sure the instrument panel brightness knob
is in the full bright position. See Instrument Panel
Brightness
on page 4‑15for more information.
If it is dark enough outside and the exterior lamp control
is off, a HEADLAMPS SUGGESTED message will
display on the Driver's Information Center (DIC).
See DIC Warnings and Messages on page 4‑52.
Turning the exterior lamp control to off a second
time, or turning on the headlamps will remove the
HEADLAMPS SUGGESTED message in the DIC. If the
parking lamps or the fog lamps were turned on instead,
the HEADLAMPS SUGGESTED message will continue
to be displayed.
The regular headlamp system should be turned on
when needed. To turn off the DRL, turn the exterior lamp control to the
off position or shift into P (Park). The DRL will stay off
until the control is toggled again or the vehicle is shifted
out of P (Park).
This procedure applies only to vehicles first sold in the
United States.
Fog Lamps
Use fog lamps for better vision in foggy or misty
conditions.
The fog lamps control is located on the multifunction
lever next to the exterior lamp control.
#
(Fog Lamps) : Turning the band to this position will
turn the fog lamps on.
When you turn the fog lamps on, the fog lamp light will
appear on the instrument panel cluster to indicate that
the fog lamps and the parking lamps are on.
If you turn the high-beam headlamps on, the fog lamps
will turn off. They will turn on again when you switch to
low-beam headlamps.
The ignition must be on for the fog lamps to operate.
Some localities have laws that require the headlamps
to be on along with the fog lamps.

Twilight Sentinel®
Twilight Sentinel®can turn the 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
®, the following will 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 the vehicle is started in a dark garage, the automatic
headlamp system come on immediately. Once the
vehicle leaves the garage, it takes about one minute for
the automatic headlamp system to change to DRL if it
is light outside. During that delay, the instrument panel
cluster may not be as bright as usual. Make sure the
instrument panel brightness control is in full bright
position. See Instrument Panel Brightness
on
page 4‑15.
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 the control band is
turned 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, the 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 4‑71to 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.
The regular headlamp system should be turned on
when needed.

The system operates to reach the 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 16°C (60°F) and 32°C (90°F). Choosing
the coldest or warmest temperature setting will
not cause the system to heat or cool any faster.
A setting of 23°C (73°F) 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
starts out blowing air at the floor but may change
modes automatically as the vehicle warms up to
maintain the chosen temperature setting. The
length of time needed for warm up depends on the
outside temperature and the length of time that has
elapsed since the 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.Manual Operation

You may notice a slight change in engine performance
when the air-conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for the vehicle to cool down. It also helps the
system to operate more efficiently.
For quick cool down on hot days press the AUTO
button and adjust the temperature to a cool, comfortable
setting. To achieve maximum cool down, do the
following: 1. Select
Hmode.
2. Press
?.
3. Select the a/c on.
4. Select the coolest temperature.
5. Select the highest fan speed. Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in the
vehicle has cooled, turn the recirculation mode off.
The air conditioning system removes moisture from the
air, so a small amount of water might drip under the
vehicle while idling or after turning off the engine.
This is normal.
?
(Recirculation) : Press to turn the recirculation
mode on or off. An indicator light comes on to show
that recirculation is on. This mode prevents outside air
from entering your vehicle. It can be used to prevent
outside air and odors from entering your vehicle and
to help cool the air inside your vehicle more quickly.
Recirculation mode is not available in defrost or
defog mode.
