Lamps on Reminder
A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp position
and the driver's door is opened with the ignition off.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
®rst sold in Canada.
The DRL system will make the front turn signal lamps
come on when the following conditions are met:
·It is still daylight and the ignition is on,
·the exterior lamp control is in the off position and
·the transmission is not in PARK (P).
When DRL are on, only the front turn signal lamps will
be on. No other exterior lamps such as the parking
lamps, taillamps, etc. will be on when the DRL are being
used. Your instrument panel will not be lit up either.
When it is dark enough outside, the front turn signal
lamps will turn off and normal low-beam headlamps will
turn on.When it is bright enough outside, the regular lamps will
go off, and the front turn signal lamps will take over.
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 approximately
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
knob is in the full bright position. See ªInstrument Panel
Brightnessº under
Interior Lamps on page 3-25.
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). This
message informs the driver that turning on the exterior
lamps is recommended.
Turning the exterior lamp control to off a second time,
or turning on the headlamps will remove the
HEADLAMPS SUGGESTED message. If the parking
lamps or the fog lamps were turned on instead,
the HEADLAMPS SUGGESTED message will continue
to be displayed.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
3-23

Twilight Sentinelžalso provides exterior illumination as
you leave the vehicle. If Twilight Sentinelžhas 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
Driver Information Center (DIC) on page 3-55to
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
ždelay 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.
Exterior Lighting Battery Saver
If the manual parking lamps or headlamps have been
left on, the exterior lamps will turn off as soon as
the ignition is turned off or RAP is active. This protects
against draining the battery in case you have
accidentally left the headlamps or parking lamps on.
The battery saver does not work if the headlamps are
turned on after the ignition switch is turned to OFF.
If you need to leave the lamps on, use the exterior lamp
control to turn the lamps back on.

Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright, or too high in
your ®eld of view, it may take you more time to
see things you need to see when it is dark
outside. Be sure to keep the HUD image dim
and placed low in your ®eld of view.
The Head-Up Display (HUD) allows you to see some of
the driver information that appears on your instrument
panel cluster.
The information may be displayed in English or metric
units and appears as an image focused out toward
the front of your vehicle. To change from English
to metric units, see
Driver Information Center (DIC) on
page 3-55.
The HUD consists of the following information:
·Speedometer
·Turn Signal Indicators
·High-Beam Indicator Symbol
·Tap-Up/Tap-Down Transmission Feature
·Check Gages Icon
·Adaptive Cruise Control Features and Indicators
·Radio Features
Be sure to continue scanning your displays, controls
and driving environment just as you would in a vehicle
without HUD. If you never look at your instrument
panel cluster, you may not see something important,
such as a warning light. Under important warning
conditions, the CHECK GAGES message will display in
the HUD. View your Driver Information Center (DIC)
for more information.

Automatic Operation
AUTO (Automatic):When this button is pressed and
the temperature is set, the system will automatically
control the inside temperature, the air delivery mode, the
air-conditioning compressor and the fan speed. AUTO
will appear on the display.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting
between 70ÉF (21ÉC) and 80ÉF (27ÉC).
Choosing the warmest or coldest temperature
setting will not cause the system to heat or cool any
faster. If you set the system at the warmest or
coldest temperature setting, the system will remain
in manual mode at that temperature and it will
not go into automatic mode.
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.You can switch from English to metric units through the
Driver Information Center (DIC). SeeDIC Controls
and Displays on page 3-55for more information.
The air-conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.
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 ªSensorsº later in
this section.
Manual Operation
wPWRx(Power/Temperature):Press the PWR
button on the left side of the climate control panel to turn
the entire climate control system on or off. Press the
up or down arrow on the switch to manually increase or
decrease the temperature inside the vehicle.
Press the PWR button on the right side of the climate
control panel to turn the passenger's climate control
system on or off. Press the up or down arrow on
the switch to manually increase or decrease the
temperature for the passenger.
If the passenger's PWR button is off, the driver's
temperature switch controls the temperature for the
entire vehicle.
3-34

?(Recirculation):Press this button to turn the
recirculation mode on or off. The air-conditioning
compressor also comes on. This mode keeps outside
air from coming in the vehicle. It can be used to prevent
outside air and odors from entering your vehicle or to
help cool the air inside your vehicle more quickly.
Recirculation is not available in defrost or
¯oor/defog mode.
Using recirculation for long periods of time may cause
the air inside your vehicle to become too dry. To prevent
this from happening, after the air in your vehicle has
cooled, turn the recirculation mode off.
Sensors
There are sensors to measure the temperature and
sun's effect on passenger comfort.
The solar sensor on your vehicle monitors the solar
radiation then 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 right side of the instrument panel near the
windshield or system will not work properly.There is also a sensor located behind the front bumper.
This sensor reads the outside air temperature and
helps maintain the temperature inside the vehicle. The
outside temperature will be displayed in the navigation
system only when the engine is running. Any cover
on the front of the vehicle could give a false reading of
the temperature.
If the outside temperature goes up, the display
temperature will not change until:
·The vehicle's speed is above 10 mph (16 km/h) for
®ve minutes.
·The vehicle's speed is above 32 mph (51 km/h) for
two and one-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 button. The automatic climate
control system uses this sensor to receive information,
so if you block or cover it, the system will not function
properly.

Fuel Gage
Your fuel gage tells you
about how much fuel you
have left when the
ignition is on.
When the needle approaches the low fuel symbol, LOW
FUEL will appear on the Driver Information Center (DIC)
display. At this time, you still have a little fuel left, but
you should get more soon.
Press RESET to acknowledge a DIC message(s).
Pressing RESET will also turn off a DIC message but
the LOW FUEL message will come on again in
10 minutes if you have not added fuel to the vehicle.Here are ®ve things that some owners ask about. All
these things are normal and do not indicate that
anything is wrong with the fuel gage.·At the gas station, the gas pump shuts off before
the gage reads the full symbol.
·It takes more (or less) fuel to ®ll up than the gage
reads. For example, the gage reads half full, but it
took more (or less) than half of the tank's
capacity to ®t it.
·The gage pointer may move while cornering,
braking or speeding up.
·The gage may not indicate the tank is empty when
the ignition is turned off.
·The gage reading may change slightly within the
®rst several minutes after starting the vehicle.
