page 3-15for additional information.
Daytime Running Lamps (DRL)/
Automatic Headlamp System
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. DRL lamps are required to
function at all times on all vehicles rst sold in Canada.
A light sensor on top of the instrument panel makes the
DRL work, so be sure it is not covered.
The DRL system will make the low-beam headlamps
come on at reduced brightness when the following
conditions are met:
The ignition is on.
The exterior lamps control is off.
The parking brake is released.
While the DRL are on, only the vehicle’s low-beam
headlamps will be on at reduced brightness. The turn
signal, taillamps, sidemarker, and other lamps will not be
on. The instrument panel will not be lit up either.
3-14

When it is dark enough outside, the DRL will turn off
and the vehicle’s headlamps and parking lamps will turn
on. The other lamps that come on with the headlamps
will also come on.
When it is bright enough outside, the headlamps will go
off and the DRL will come on.
To idle the vehicle with the DRL off, turn the exterior
lamp control off and then do one of the following:
Turn the exterior lamp control to the parking lamp
position.
Turn the exterior lamp control to the headlamp
position.
Turn the exterior lamp control from AUTO to off and
back to AUTO.
This feature is not available for vehicles rst sold in
Canada.
To turn off the automatic headlamp feature when it is
dark outside, move the exterior lamp control to the
parking lamp position. The parking lamps remain on and
the headlamps turn off. The fog lamps also go on if
they were on previously.
As with any vehicle, the regular headlamp system
should be turned on when needed.
Fog Lamps
If your vehicle has fog
lamps, the button is
located in the center of the
exterior lamps control
on the left side of
the steering column.
Press the fog lamps button to turn the lamps on or off.
While the high-beam headlamps are on, the fog
lamps are off.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Exterior Lighting Battery Saver
If the parking lamps or headlamps have been left on
after the ignition has been turned to off, the exterior
lamps will turn off after about 10 minutes. This protects
the battery from being drained.
Use the exterior lamp control to turn the lamps back on,
if they are still needed.
3-15

Overhead Console Reading Lamps
Your vehicle may have reading lamps located on
the overhead console. Press the lens to turn them on
and off.
Rear Assist Handle Reading Lamps
Your vehicle may have reading lamps located near
the rear assist handles. Press the lens to turn them on
and off.
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 put the charge back in. When the
state of charge is high, the voltage is lowered slightly to
prevent overcharging. If the vehicle has a voltmeter gage
or 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 loads are on: 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, the Driver Information Center (DIC)
message might display Battery Saver Active. 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 3-58.
3-18

You can also select modes by using the following
buttons:
h(Recirculate):Press this button to recirculate
cabin air through the vehicle. It can be used to
help reduce the outside air and odors that enter your
vehicle or to help heat or cool the air inside your vehicle
quicker. An indicator light below the button will come
on in this mode. 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. To prevent the
air inside the vehicle from becoming stale, after
ve minutes recirculate will allow some outside air into
the vehicle.
#(Air Conditioning):Press this button to turn the
air conditioning system on or off. When this button
is pressed, an indicator light below the button will come
on to let you know the air conditioning is activated.
Air conditioning can be selected in any mode as long as
the fan switch is on. The indicator light will change
with each button press even when conditions prevent
operation.
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 the vent air mode.
2. Select the recirculation mode.
3. Select the air conditioner.
4. Select the coolest temperature.
5. Select the highest fan speed.
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.
Using these settings together for long periods of time
may cause the air inside the vehicle to become too dry.
To prevent this, after ve minutes recirculate will
allow some outside air into the vehicle.
Defogging and Defrosting
Fog on the inside of the vehicle is a result of high humidity
causing moisture to condense on the cool window glass.
This can be minimized if the climate control system is
used properly. There are two modes to clear frost or fog
from the windshield. Use the defog mode to clear the
windows of condensation and to warm the vehicle’s
occupants. Use the defrost mode to remove frost or
condensation from the windshield quickly.
See “Rear Window Defogger” later in this section for
information on clearing the rear window of fog or ice.
3-22

Turn the right knob to select the defog or defrost mode.
Do not drive the vehicle until all windows are clear.
-(Defog):This mode directs half of the air to
the windshield and the side window outlets and half to
the oor outlets. When you select this mode, the system
turns recirculation off and runs the air conditioning
compressor unless the outside temperature is near or
below freezing. Pressing the recirculation button
will have no effect other than turning on the indicator
light while in defog mode.
0(Defrost):This mode directs most of the air to the
windshield and the side window outlets, with some
air directed to the oor outlets. When you select this
mode, the system turns recirculation off and runs the air
conditioning compressor unless the outside temperature
is near or below freezing. Pressing the recirculation
button will have no effect other than turning on
the indicator light while in defrost mode.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear):Press the button to turn the rear window
defogger on or off. An indicator light below the button will
come on to let you know that the rear window defogger
is activated.
The rear window defogger will only work when the ignition
is in ON/RUN. The rear window defogger will stay on for
about 20 minutes after the button is pressed. If turned on
again, the defogger will only run for about 20 minutes
before turning off. The defogger can also be turned off by
pressing the button again or by turning off the engine.
Do not drive the vehicle until all windows are clear.
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 your warranty. Do not attach a
temporary vehicle license, tape, a decal or anything
similar to the defogger grid.

Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(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.
-(Floor/Defog):Press this button to direct the air
between the windshield, oor outlets and side windows.
When you select this mode, the system turns
recirculation off and runs the air conditioning compressor
unless the outside temperature is near or below
freezing. Pressing the recirculation button will have no
effect other than turning on the indicator light while
in oor/defog mode.
1(Defrost):Press this button to direct most of the
air to the windshield, with some air directed to the
side windows. In this mode, the system will automatically
turn off the recirculation and run the air conditioning
compressor, unless the outside temperature is near or
below freezing. Pressing the recirculation button will
have no effect other than turning on the indicator light
while in defrost mode.
Do not drive the vehicle until all windows are clear.
Sensors
The solar sensor on the vehicle monitors the solar heat
and the air inside of the vehicle. This information is
used to maintain the selected temperature 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 in the
center of the instrument panel, near the windshield,
or the system will not work properly.
