Lighting Features
Entry Lighting
The vehicle has an illuminated entry
feature.
When the doors are opened, the
dome lamps will come on if the
dome override button is in the
extended position. If the dome
override button is pressed in,
the lamps will not come on.
Exit Lighting
The interior lamps come on when
the key is removed from the ignition.
They turn off automatically in
20 seconds. The lights do not come
on if the dome override button is
pressed in.
Battery Load
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.

6(Floor): Air is directed to the
floor outlets, with some air directed
to the windshield and side window
outlets. In this mode, the system
automatically selects outside air.
Recirculation cannot be selected
in floor mode.
-(Defog): This mode clears the
windows of fog or moisture. Air is
directed to the windshield, floor
outlets, and side window vents.
0(Defrost): This mode removes
fog or frost from the windshield
more quickly. Air is directed to the
windshield and the side window
vents, with some air directed to
the floor vents. The system
automatically forces outside air
into the vehicle. The recirculation mode cannot be
selected in the defog or defrost
mode. When either mode is
selected, the system runs the air
conditioning compressor, unless
the outside temperature is close
to freezing.
Do not drive the vehicle until all the
windows are clear.
:(Outside Air):
Press to
turn the outside air mode on.
An indicator light comes on to
show that outside air is on.

may fog when the weather is cold
and damp. To clear the fog, select
either the defog or defrost mode
and increase the fan speed.
The recirculation mode can be
turned off by pressing the outside
air button, or by turning off the
ignition.#(Air Conditioning): Press to
turn the air conditioning system on
or off. An indicator light comes on to
show that the air conditioning is on.

This is normal.
Rear Window Defogger
For vehicles with a rear window
defogger, a warming grid is used to
remove fog from the rear window.
<(Rear): Press to turn the
rear window defogger on or off.
An indicator light on the button
comes on to show that the rear
window defogger is on. The rear window defogger only
works when the ignition is in

defogger stays on for approximately
10 minutes after the button is
pressed, unless the ignition is
turned to ACC/ACCESSORY or
LOCK/OFF. The defogger can
also be turned off by turning off
the engine.
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.

Interior Care
The vehicle's interior will continue to
look its best if it is cleaned often.
Although not always visible,
dust and dirt can accumulate
on the upholstery. Dirt can damage
carpet, fabric, leather, and plastic
surfaces. Regular vacuuming is
recommended to remove particles
from the upholstery. It is important to
keep the upholstery from becoming
and remaining heavily soiled. Soils
should be removed as quickly as
possible. The vehicle's interior may
experience extremes of heat that
could cause stains to set rapidly.Lighter colored interiors may require
more frequent cleaning. Use care
because newspapers and garments
that transfer color to home
furnishings may also transfer
color to the vehicle's interior.
When cleaning the vehicle's interior,
only use cleaners specifically
designed for the surfaces being
cleaned. Permanent damage may
result from using cleaners on
surfaces for which they were not
intended. Use glass cleaner only
on glass. Remove any accidental
over-spray from other surfaces
immediately. To prevent over-spray,
apply cleaner directly to the
cleaning cloth.Notice:
Using abrasive cleaners
when cleaning glass surfaces on
the vehicle, could scratch the
glass and/or cause damage to
the rear window defogger. When
cleaning the glass on the vehicle,
use only a soft cloth and glass
cleaner.
Many cleaners contain solvents that
may become concentrated in the
vehicle's breathing space. Before
using cleaners, read and adhere to
all safety instructions on the label.
While cleaning the vehicle's interior,
maintain adequate ventilation by
opening the vehicle's doors and
windows.
Dust may be removed from small
buttons and knobs using a small
brush with soft bristles.
Products that remove odors from
the vehicle's upholstery and clean
the vehicle's glass can be obtained
from your dealer.
