Interior Lamps
Instrument Panel Brightness
This feature controls the instrument panel lights.
The control for this feature is located on the exterior
lamps control. Your parking lamps must be on for this
feature to work. Turn the control clockwise to brighten
the lights or counterclockwise to dim them.
Courtesy Lamps
When any door is opened, several lamps come on.
These lamps are courtesy lamps. They make it easy for
you to enter and leave your vehicle. You can also
turn these lamps on by turning the exterior lamps control
all the way clockwise.
Some of the lamps have switches so you can turn them
on, even when the doors are closed. These lamps
are reading lamps.
Entry Lighting
Your vehicle may be equipped with courtesy lamps that
will come on and stay on for a set time whenever
you press UNLOCK on the remote keyless entry
transmitter (if equipped).
If you open a door, the lamps will stay on while it's open
and then turn off automatically about 25 seconds after
you close it. If you press UNLOCK and don't open
a door, the lamps will turn off after about 40 seconds.Entry lighting includes a feature called theater dimming.
With theater dimming, the lamps don't just turn off at
the end of the delay time. Instead, they slowly dim after
the delay time until they go out. The delay time is
canceled if you turn the ignition key to ON or press
the power door lock switch. The lamps will dim
right away.
When the ignition is on, illuminated entry is inactive,
which means the courtesy lamps won't come on unless
a door is opened.
Delayed Entry Lighting
Delayed entry lighting illuminates the interior for a
period of time after all the doors have been closed.
The ignition must be off for delayed entry lighting
to work. Immediately after all the doors have been
closed, the delayed entry lighting feature will continue to
work until one of the following occurs:
·The ignition is moved to ON,
·the doors are locked, or
·an illumination period of 25 seconds has elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled and the
interior lamps will remain on because a door is open.
3-17

Delayed Exit Lighting
This feature illuminates the interior for a period of time
after the key is removed from the ignition.
The ignition must be off for delayed exit lighting to work.
When the key is removed, interior illumination will
activate and remain on until one of the following occurs:
·The ignition is moved to ON,
·the power door locks are activated, or
·an illumination period of 25 seconds has elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled and the
interior lamps will remain on because a door is open.
Parade Dimming
The instrument panel has an added feature called
parade mode. This feature prohibits the dimming of your
instrument panel displays during the daylight while
the headlamps are on so that you'll still be able to see
the displays.
Reading Lamps
Your vehicle may be equipped with reading lamps that
are located on the assist handles in the headliner.
These lamps and the interior courtesy lamps come on
when any door is opened. Press the lens to turn
them on. Press it again to turn them off.
Dome Lamp
If your vehicle has this feature, the dome lamp will
come on when you open a door. You can also turn this
lamp on by turning the exterior lamps control clockwise
as far as it will go. Vehicles that have the optional
sunroof do not have a dome lamp.
Battery Rundown Protection
Your vehicle has a feature to help prevent you from
draining the battery in case you accidentally leave on the
interior courtesy lamps, reading/map lamps, visor
vanity lamps, trunk lamp or glove box lamps. If you leave
any of these lamps on, they will automatically turn off
after 10 minutes, if the ignition is moved to OFF.
The lamps won't come back on again until you do
the following:
·Turn the ignition on, or
·turn the exterior lamps control off, then on again.
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.
Battery rundown protection will also work if the
headlamps are left on. After having been left on for
10 minutes, the headlamps and the parking lamps will
¯ash three times. They will remain on for one more
minute before being turned off automatically.
3-18

Ashtrays and Cigarette Lighter
Your vehicle may have ashtrays and a cigarette lighter.
The front ashtray may be on the instrument panel or
on the console. To remove the instrument panel ashtray,
open it, push down on the locking tab and pull out
the ashtray.
To remove the console ashtray, open the ashtray door,
lift up on the ashtray and pull it out.
If your vehicle is equipped with a center console, a rear
ashtray may be located located behind a small door
at the rear of the console. Push on the right side of the
door. The ashtray will then turn to the right for usage.
You can only access the ashtray by pushing on the
door's right side. To remove the ashtray, push down on
the snuffer located in the middle of the ashtray and
lift it out.
Notice:Don't put papers or other ¯ammable items
into your ashtrays. Hot cigarettes or other smoking
materials could ignite them, causing a
damaging ®re.
Notice:Don't hold a cigarette lighter in with your
hand while it is heating. If you do, it won't be able to
back away from the heating element when it's
ready. That can make it overheat, damaging the
lighter and the heating element.
To use the lighter, just push it in all the way and let go.
When it's ready, it will pop back out by itself.

At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety
belts replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag
system does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace
blade inserts that appear worn or damaged or that
streak or miss areas of the windshield. Also see
Cleaning the Outside of Your Vehicle on page 5-88.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be
required. See
Part D: Recommended Fluids and
Lubricants on page 6-16.
Automatic Transaxle Check
Check the transaxle ¯uid level; add if needed. SeeAutomatic Transaxle Fluid on page 5-24. A ¯uid loss
may indicate a problem. Check the system and repair
if needed.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
speci®ed in Part D.
Body Lubrication Service
Lubricate all hinges and latches, including those for the
body doors, hood, secondary latch, pivots, spring
anchor, release pawl, rear compartment, glove box door,
console door and any folding seat hardware. Part D
tells you what to use. More frequent lubrication may be
required when exposed to a corrosive environment.
