Fog Lamps
Your vehicle has fog lamps. You can use them for
better vision in foggy or misty conditions. Your parking
lamps and/or low-beam headlamps must be on for
your fog lamps to work.
The fog lamp button is
located in the exterior
lamps control.
Press the button to turn the fog lamps on while the
headlamps or parking lamps are on. Press the button
again to turn them off. An indicator light will glow in the
button when the fog lamps are on.
Remember, fog lamps alone will not give off as much
light as your headlamps. Never use your fog lamps
in the dark without turning on the headlamps.
The fog lamps will go off whenever your high-beam
headlamps come on. When the high beams go off, the
fog lamps will come on again.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Instrument Panel Brightness
D(Instrument Panel Brightness):This feature
controls the brightness of the instrument panel lights.
The thumbwheel for this feature is located next to
the exterior lamp control.
Turn the thumbwheel up or down to brighten or dim the
instrument panel lights and the radio display. The
instrument panel lights, cluster, and radio display do not
dim to complete darkness. Turn the thumbwheel all
the way up to turn the dome lamps on.
Dome Lamp
The dome and footwell lamps come on when any door
is opened. The dome lamps are located in the cargo
and front area of the vehicle.
The dome and footwell lamps can be turned on by
turning the thumbwheel, located next to the exterior
lamps control, all the way up. In this position, the lamps
remain on whether a door is opened or closed.
3-19

Dome Lamp Override
E(Dome Lamp Override):You can use the dome
override button, located below the exterior lamps control,
to set the dome and footwell lamps to come on
automatically when a door is opened, or to remain off.
To turn the lamps off, press the button into the in
position. With the button in this position, the dome lamps
will remain off when the doors are open. To return the
lamps to automatic operation, press the button again
and return it to the out position. With the button in this
position, the dome lamps will come on when you
open a door.
Exit Lighting
With exit lighting, the interior lamps will come on when
you remove the key from the ignition. The lamps will not
come on if the dome override button is pressed in.
Reading Lamps
Your vehicle has reading lamps. Press the button
located next to the lamp to turn them on or off.
These lamps will not come on with the dome lamps.
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, 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.
Battery Run-Down Protection
This feature shuts off the dome lamp if it is left on for
more than 20 minutes when the ignition is in LOCK. This
will help prevent your battery from running down.
3-20

The air conditioning will not function if the fan is turned
off. If air conditioning is selected with fan off, the
indicator light ashes three times and then turns off.
A slight change in engine performance may occur 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.
The air conditioning system removes moisture from the
air, so sometimes there may be a small amount of
water dripping underneath the vehicle while idling or
after turning off the engine. This is normal.
9(Fan):Turn the center knob on the control panel to
control the fan speed. Turn the knob clockwise or
counterclockwise to increase or decrease the fan speed.
9(Off):Turn the center knob to this position to turn
the fan off. With the fan off, you may still experience
airow from the system that increases with vehicle
speed depending on the mode and temperature settings.
Enable recirculation mode to stop this airow from
occurring.
@(Recirculation):Press the center of the fan
control knob to recirculate air inside the vehicle and
prevent outside air from coming in. It can be used
to prevent outside odors from entering the vehicle and
cool the air inside the vehicle more quickly. Pressthis button to turn the recirculation mode on or off. An
indicator light on the button comes on to show that
the recirculation mode is activated.
Recirculation is available in the bi-level, and vent
modes. Recirculation is not available while in oor,
oor/defog and defrost mode. If recirculation is selected
in these modes, the indicator ashes three times
indicating it is not available in that mode. When the
recirculation mode is turned on, the air conditioning turns
on automatically.
When it is hot enough outside, the recirculation mode
may turn on automatically to help improve cooling
performance. The indicator light will be lit to show this
mode is active. If the recirculation button is pressed
while in this mode, the light will ash three times
and stay on to indicate that recirculation may not be
shut off.
The right knob on the control panel is used to direct the
airow inside the vehicle. In-between modes are
available by moving the right control knob between
modes with symbols. The in-between mode is a
combination of the two modes that the control is
centered between.
Turn the right knob to select one of the following modes:
H(Vent):This mode directs air to the instrument
panel outlets.
