Courtesy Lamps
If it is dark enough outside, when any door is opened,
several lamps go on. They make it easy for you to enter
and leave the vehicle. You can also turn these lamps
on by sliding the INTERIOR lever all the way to the top.
Entry Lighting
If it is dark enough outside when you press the unlock
button on the remote keyless entry transmitter, the
interior courtesy lamps will turn on and stay on for about
40 seconds. The lamps will turn off immediately by
pressing the lock button on the remote keyless entry
transmitter, turning the ignition key to RUN or activating
the power door locks.
Delayed Entry Lighting
If it is dark enough outside when you open the door, the
interior lamps will turn on. When you close the door with
the ignition off, the interior lamps will stay on for up to
25 seconds or until the ignition is turned to an on position.
When the lamps turn off as a result of the 25 second timer
or the ignition switch being turned on, the lighting will
deactivate by way of the theater dimming effect. Locking
the doors will override the delayed entry lighting feature
and the lamps will turn off right away.
Theater Dimming
This feature allows for a three to ve-second fade out of
the courtesy lamps instead of immediate turn off.
Delayed Exit Lighting
If it is dark enough outside when you remove the key
from the ignition, the interior lamps will turn on and stay
on for about 25 seconds. This will give you time to
nd the door pull handle or lock switches. Once the key
is inserted into the ignition the exit lighting will be
cancelled and the lighting will fade out.
Perimeter Lighting
If it is dark enough outside when the unlock button on
the remote keyless entry transmitter is pressed, the
DRL, parking lamps and back-up lamps will come on.
Personal Choice Programming
This feature can be programmed in the on or off mode
for each transmitter.
If your vehicle is equipped with the Driver Information
Center (DIC), you must use it to program this feature.
SeeDriver Information Center (DIC) on page 3-45.
To turn the feature off, do the following:
1. Close all the doors and turn the ignition on. Keep
all doors closed throughout this procedure.
2. Press and hold LOCK on the power door lock
switch throughout this procedure. All the doors
will lock.
3-18

To recall the climate control settings last stored on your
transmitter, press the unlock button on your remote
keyless entry transmitter and put the ignition in
ACCESSORY or RUN. The settings will be recalled.
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.
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 briey when you start the
engine just to let you know they are 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 is 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 are a big help.
Your vehicle may also have a DIC that works along with
the warning lights and gages. SeeDriver Information
Center (DIC) on page 3-45.
The volume of your vehicle’s warning chimes can be
adjusted. For information seeChime Level Adjustment
on page 3-82.
