Wiper Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers are turned on and have
completed eight wipe cycles within four minutes.
When the ignition is turned to LOCK/OFF, the
wiper-activated headlamps immediately turn off. The
wiper-activated headlamps also turn off if the windshield
wipers are turned off.
Headlamps on Reminder
If you leave the exterior lamp buttons for the headlamps
or parking lamps on, remove the key from the ignition
and open the driver's door, you will hear a continuous
warning chime. The chime will turn off when the lamps
are turned off.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
Fully functional daytime running lamps are required on
all vehicles first sold in Canada.
A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL, so be
sure it is not covered.The DRL system makes the low-beam headlamps turn
on at reduced brightness in daylight when the following
conditions are met:
.The engine is running.
.The exterior lamp button for the headlamps is off.
When the DRL are on, only the low-beam headlamps
will be on. The parking lamps, taillamps, sidemarker
and other lamps will not be on.
When it is dark enough outside, the low-beam
headlamps will come on. The other lamps that turn on
with the headlamps will also turn on. When it is bright
enough outside, the regular lamps will go off, and the
low-beam headlamps change to the reduced brightness
of DRL.
To turn off all exterior lighting at night when the vehicle
is parked, turn the exterior lamp control to the off
position. See Exterior Lamps
on page 4‑10for more

the left of the steering column.
#(Fog Lamps):Press to turn the fog lamps on or off.
A light comes on in the instrument panel cluster when
the fog lamps are in use. See Instrument Panel Cluster
on page 4‑28. The ignition must be in the ON/RUN
position for the fog lamps to work.
The fog lamps will go off when the headlamps are
changed to high-beam.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Cornering Lamps
For vehicles with this feature, the cornering lamps come
on when: the headlamps or parking lamps are on, the
vehicle is not in P (Park), and you signal a turn with the
turn signal/multifunction lever. They provide more light
for cornering.
Exterior Lighting Battery Saver
If the exterior lamp button has been left on, the exterior
lamps will turn off about 10 minutes after the ignition is
turned to LOCK/OFF and a door has been opened. This
protects against draining the battery if the headlamps or
parking lamps are accidentally left on. If the lamps need
to be left on for more than 10 minutes, use the exterior
lamp control to turn the lamps back on after the ignition
is turned to LOCK/OFF and any door is opened.

Courtesy Lamps
When any door is opened, several lamps turn on
making it easier for you to enter and exit the vehicle.
Turn the instrument panel brightness control completely
clockwise to manually turn on these lamps.
Entry Lighting
If it is dark enough outside when you press the unlock
button on the remote keyless entry transmitter, the
interior courtesy lamps will turn on and stay on for about
40 seconds. The lamps can be turned off immediately
by pressing the lock button on the remote keyless entry
transmitter, turning the ignition key to ON/RUN or
activating the power door locks.
Delayed Entry Lighting
The interior lamps will turn on if you open the door
when it is dark enough outside. When you close the
door with the ignition off, the interior lamps will stay on
for up to 25 seconds or until the ignition is turned to an
on position. When the lamps turn off as a result of the
25 second timer or the ignition switch being turned
on, the lighting will deactivate by way of the theater
dimming effect. Locking the doors will override the
delayed entry lighting feature and the lamps will turn off
right away.
Theater Dimming
This feature allows for a three to five second fade out of
the courtesy lamps instead of immediate turn off.
Delayed Exit Lighting
If it is dark enough outside when you remove the key
from the ignition, the interior lamps will turn on and
stay on for about 25 seconds. This will give you time
to find the door pull handle or lock switches. Once the
key is inserted into the ignition, the exit lighting will be
cancelled and the lighting will fade out.
Perimeter Lighting
If it is dark enough outside when the unlock button on
the remote keyless entry transmitter is pressed, the
DRL, parking lamps and back-up lamps will come on.
This feature can be programmed on for various
amounts of time in seconds for each transmitter.

Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery's temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery's state of charge is low, the voltage
is raised slightly to quickly bring the charge back up.
When the state of charge is high, the voltage is lowered
slightly to prevent overcharging. If the vehicle has a
voltmeter gauge or a voltage display on the Driver
Information Center (DIC), you may see the voltage
move up or down. This is normal. If there is a problem,
an alert will be displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be spinning
fast enough at idle to produce all the power that is
needed for very high electrical loads.
A high electrical load occurs when several of the
following are on, such as: headlamps, high beams,
fog lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory power outlets.EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator's output
and the vehicle's electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands
of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the highest
levels of corrective action, this action may be noticeable
to the driver. If so, a Driver Information Center (DIC)
message might be displayed, such as BATTERY
SAVER ACTIVE, BATTERY VOLTAGE LOW, or
LOW BATTERY. If this message is displayed, it is
recommended that the driver reduce the electrical
loads as much as possible. See DIC Warnings and
Messages on page 4‑49.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle's
battery against drainage from the interior lamps,
or garage door opener. When the ignition is turned
off, the power to these features will automatically turn
off after 10 minutes. Power will be restored for an
additional 10 minutes if any door is opened, the trunk
is opened or the courtesy lamp switch is turned on.

-(Floor/Defog):This clears the windows of fog or
moisture. Air is directed to the windshield and side
window outlets and to the floor outlets. The system runs
the air conditioning compressor unless the outside
temperature is near or below freezing.
0(Defrost): This mode clears the windshield of fog
or frost more quickly. Air is directed to the windshield
and side window outlets. The system runs the air
conditioning compressor unless the outside temperature
is near or below freezing.
#(Air Conditioning): Press to turn the air
conditioning system on or off. An indicator light
below the button comes on to show that this mode
is on. Air conditioning can be selected in any mode
as long as the fan knob is not in the off position.
On hot days during the vehicle's initial start-up, 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 quicker cool down on hot days, do the following:
1. Select
H.
2. Select
h.
3. Select
#.
4. Select the coolest temperature.
5. Select the highest fan speed.
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.
h(Recirculation): Press to turn the recirculation
mode on. An indicator light below the button comes on
to show that this mode is on. This mode recirculates
and helps to quickly cool the air inside the vehicle.
It can be used to prevent outside air and odors from
entering the vehicle. This mode cannot be selected
while in the defog or defrost modes. If you try to select
the recirculation mode, the indicator light flashes
three times and turns off.
Operation in this mode during periods of high humidity
and cool outside temperatures may result in increased
window fogging. If window fogging is experienced,
select the defrost mode.

The rear window defogger only works when the
ignition is in ON/RUN. The rear window defogger stays
on for about 20 minutes after the button is pressed if
traveling at slow speeds. At higher vehicle speeds, the
rear defogger may stay on continuously. If turned on
again, the defogger only runs for about 10 minutes
before turning off. The defogger can be turned off by
pressing the button again, by turning the ignition to
ACC/ACCESSORY or ON/RUN, or by turning off the
engine. If the vehicle has heated outside rearview mirrors, the
mirrors heat to help clear fog or frost from the surface
of the mirror when the rear window defogger is on.
See
Outside Heated Mirrors
on page 3‑34for more
information.
Notice: Do not use anything sharp on the inside of
the rear window. If you do, you could cut or damage
the warming grid, and the repairs would not be
covered by the vehicle warranty. Do not attach a
temporary vehicle license, tape, a decal, or anything
similar to the defogger grid.

AUTO (Automatic Mode)
1. Turn the fan control to AUTO.
2. Turn the mode control to AUTO.
3. Adjust the temperature to a comfortable settingbetween 68°F (21°C) and 78°F (26°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool
any faster. In cold weather, the system starts at
reduced fan speeds to avoid blowing cold air
into the vehicle until warmer air is available. The
system will start out blowing air to the floor, but
may change modes automatically as the vehicle
warms up to maintain the chosen temperature
setting. The length of time needed to warm the
interior depends on the outside temperature.
4. Wait a few minutes for the system to automatically regulate. Then adjust the temperature as
necessary to find your comfort setting.
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 “Sensors”later in
this section.
After the vehicle is started, the display shows the
interior temperature settings. When the ENG/MET (English/metric) button on the
Driver Information Center (DIC) is pressed, the display
shows readings in Fahrenheit or Celsius. Use the
ENG/MET button to toggle between the readings.
AUTO (Automatic Air Conditioning):
If AUTO is
selected on the fan or mode control, the system
automatically controls the air conditioning compressor.
The A/C compressor runs automatically even at cool
outside temperatures in order to dehumidify the air. The
A/C indicator light is lit when the system is operating
automatically. Press the A/C button on the fan control to
turn off the A/C. To clear windows better in defog or
defrost modes, the A/C compressor runs automatically
in damp cool conditions.
h(Auto Recirculation): If AUTO is selected on
either the fan or mode control, the system automatically
controls the supply of fresh outside air or recirculates
the interior air to cool the car faster. The indicator light
on the recirculation button will light whenever the
system switches to recirculation. You may force outside
air by pressing the outside air button. The next time
AUTO fan or mode is selected, it will reset back to
AUTO operation.
