When the DRL are on, only your front turn signal lamps
will be on. The headlamps, taillamps, sidemarker and
other lamps won't be on. Your instrument panel won't
be lit up either.
When it's dark enough outside, your front turn signal
lamps will turn off and your vehicle's headlamps and
parking lamps will turn on. The other lamps that come
on with your headlamps will also come on.
When it's bright enough outside, your headlamps will go
off and your front turn signal lamps will come on.
To idle your vehicle with the DRL and automatic
headlamp control off, set the parking brake while the
ignition is in OFF or LOCK. Then start your vehicle.
The DRL, headlamps and parking lamps will stay off
until you release the parking brake.
To turn off the automatic headlamp feature when it's
dark outside, move the exterior lamp control to the
parking lamp position. Your parking lamps will remain
illuminated and your headlamps will turn off.
As with any vehicle, you should turn on the regular
headlamp system when you need it.Delayed Headlamp Illumination
Delayed headlamp illumination provides a period of
exterior lighting as you leave your vehicle's area. The
feature is activated when your vehicle's headlamps are
on due to the automatic headlamp control feature
described previously in this section, and when your
vehicle's ignition is turned off. Your headlamps will
then remain on until the headlamp switch is moved from
OFF to the parking lamp position or until a 90 second
lighting period has ended.
If you turn off the ignition with the headlamp switch in
the parking lamp or headlamp position, the delayed
headlamp illumination cycle will not occur.
You can customize the vehicle to activate delayed
headlamp illumination when your vehicle's ignition
is turned off under the conditions described above,
or you may choose not to activate this feature under
any conditions.

2-44
You can turn the feature on and off when you perform
the following sequence:
1. Turn the ignition key to RUN.
2. Close all the doors.
3. Press and hold the power door lock switch. While
holding the door lock switch, cycle the headlamp
switch on and then off two times.
4. Release the power door lock switch. These steps
must be carried out in a time period of less than
10 seconds, followed by a delay period of no more
than 10 seconds.
5. Then, press and hold the power door unlock switch.
While holding the door unlock switch, turn the
headlamp switch on and then off two times. Release
the courtesy door unlock switch. These operations
must be carried out in a time period of less than
10 seconds.
After releasing the door unlock switch, a single chime
will be heard if the delayed headlamp illumination
function has been disabled; two chimes will be heard
if the feature has been enabled. Disconnecting the
vehicle's battery for up to a year will not change the
programmed operation of this feature.Interior Lamps
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.
Illuminated Entry
Your courtesy lamps will come on and stay on for a
set time whenever you press UNLOCK on the remote
keyless entry transmitter.
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.

2-45
Illuminated entry 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 RUN
or START, so 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 lights your vehicle's interior for
a period of time after all the doors have been closed.
The ignition must be off for delayed entry lighting to
work. Just 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 in RUN, or

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.
Delayed Exit Lighting
This feature illuminates the interior for a period of time
after the ignition key is removed from the ignition.
The ignition must be off for delayed exit lighting to
work. When the ignition key is removed, interior
illumination will activate and remain on until one
of the following occurs:

The ignition is in RUN, or

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.

The reading lamps are located on the underside of the
rearview mirror.
Use the switch next to each lamp to turn them on

It can help keep them from falling over during sharp
turns or quick starts and stops.
The net isn't for larger, heavier loads. Store those in the
trunk as far forward as you can.
You can unhook the net so that it will lie flat when
you're not using it.

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.
NOTICE:
Don't hold a cigarette lighter in with your hand
while it is heating. If you do, it won't be able to

2-61 Speedometer and Odometer
The speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
The odometer shows how far your vehicle has been
driven in either miles (used in the United States) or
in kilometers (used in Canada).
Your vehicle has a tamper
-resistant odometer. If you see
ERROR, you'll know someone has probably tampered
with it and the numbers may not be accurate.
You may wonder what happens if your vehicle needs a
new odometer installed. If the new one can be set to the
mileage total of the old odometer, then that will be done.
But if it can't, then it will be set at zero and a label must
be put on the driver's door to show the old mileage
reading when the new odometer was installed.Trip Odometer
The trip odometer tells how far you have driven since
you last reset it. To set it to zero, press the button on
the right side of the instrument panel cluster.
The trip/select reset switch will go back and forth
between the odometer and the trip odometer if the button
is pressed and released within 1.5 seconds. If the button is
pressed and held for longer than 1.5 seconds while in the
trip odometer mode, it will be reset to zero. If the button
is pressed and held for longer than 1.5 seconds while in
the odometer mode, it will have no effect.
Warning Lights, Gages
and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save you or
others from injury.

2-62
Warning lights come on when there may be or is a
problem with one of your vehicle's functions. As you
will see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to let you know they're working. If you
are familiar with this section, you should not be alarmed
when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle's functions. Often gages and
warning lights work together to let you know when
there's a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual's advice.
Waiting to do repairs can be costly
-- and even
dangerous. So please get to know your warning lights
and gages. They're a big help.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for about eight seconds to remind people to
fasten their safety belts, unless the driver's safety belt is
already buckled.
The safety belt light will
also come on and stay on
for about 20 seconds,
then it will flash for
about 55 seconds.
If the driver's belt is already buckled, neither the chime
nor the light will come on.
