Instrument Panel Brightness Control
You can brighten or dim the instrument panel lights by
moving the LIGHTS knob. If you turn the knob past
MAX, your courtesy or interior lamps will come on.
Courtesy Lamps
When any door is opened, several lamps come on. These
lamps are courtesy lamps. They make it easier to see as
you enter and exit your vehicle. You can also turn these
lamps on by twisting or turning the interior lights knob
all the way to the right.

rearview mirror.
Use the switch next to each lamp to turn them on
and off.
Dome Lamp (If Equipped)
The dome lamp will come on when you open the doors.
Battery Rundown Protection
Your vehicle has a feature to help prevent you from
draining the battery in case you accidentally leave the
interior courtesy lamps, reading/map lamps, visor vanity
lamps, trunk lamp, underhood lamp or glove box lamps
on. If you leave any of these lamps on, they will
automatically turn off after 20 minutes, if the ignition is
in OFF. The lamps won't come back on again until you:

Turn the ignition on,

turn the lamp switch off, then on, or

open a door.
If your vehicle has less than 15 miles (25 km) on the
odometer, the battery saver will turn off the lamps after
only three minutes.

With retained accessory power, your power windows,
audio system and sunroof will continue to work up to
10 minutes after the ignition key is turned to OFF and
before any of the doors are opened.
Mirrors

are sitting in a comfortable driving position.

CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
Charging System Light
The charging system light
will come on briefly when
you turn on the ignition, as
a check to show you it's
working. Then it should
go out.
If it stays on, or comes on while you are driving, you
may have a problem with the charging system. It could
indicate that you have a loose accessory belt or another
electrical problem. Have it checked right away. Driving
while this light is on could drain your battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and air conditioner.
