Delayed Locking
Delayed locking allows the doors to be locked while
passengers are exiting the vehicle. This feature also
provides a brief time period after all the doors are
closed, but before the doors are locked, in which the
doors may be reopened. Delayed locking is user
programmable for enabling or disabling the feature.

2-11
Delayed locking is activated when a door lock switch is
pressed while the key is not in the vehicle's ignition, and
a door is open. The door lock switch may be either the
lock switch on the door or on the remote keyless entry
transmitter (see ªRemote Keyless Entryº later in this
section for more details). The doors do not lock when
the lock switch is pressed, but instead, three chimes are
heard. These chimes indicate that the delayed locking
feature has been activated.
You have three actions possible once delayed locking
is activated:

Cancel the delayed locking by pressing the unlock
switch or by fully inserting the key in the ignition.

Override the delayed locking feature and lock the
doors immediately by pressing the lock switch a
second time.

Let the delayed locking feature complete the locking
of the vehicle.
If you wish to let the delayed locking feature complete
the locking of the vehicle, no additional action is
required. The delayed locking feature will lock the doors
automatically after all the doors have been closed for a
period of five seconds. During this five second period,
any door may be reopened, at which time the three
possible actions shown above are again available.You may also customize your vehicle to activate the
delayed locking feature as described above, or you
may choose to completely disable the feature at all
times. If disabled, the power door locks will activate
immediately when a power door lock switch is pressed.
The enabled/disabled state of the delayed locking
feature will be toggled when you perform the following
sequence with the doors closed and the ignition key
in RUN:
1. Apply your regular brakes.
2. Press and hold the power door unlock switch. While
holding the door unlock switch, move the shift lever
out of and back into PARK (P).
After an initial transaxle cycle, each additional cycle will
toggle the enable/disable state of the delayed locking
feature. During this procedure, the chime will sound,
providing you with feedback. In Mode 1, a single chime
will be heard if the delayed locking feature is disabled.
In Mode 2, two chimes will be heard if the feature is
enabled. When the door unlock switch is released, the
vehicle will remain in the most recent operating mode.
Disconnecting the vehicle battery for up to a year will
not change the programmed mode of the delayed
locking feature.

2-12
Illumination on Remote Activation
This feature provides interior lighting when a remote
keyless entry door unlock command is received and
executed by your vehicle. Your ignition must be off for
the illumination on remote activation feature to work.
The interior lamps will light until either the ignition is
turned to RUN or a period of 40 seconds has elapsed.
If a door is opened during the illumination period, the
timed lighting will be canceled, and the interior lamps
will remain on since a door is open.
Matching Transmitter(s) To Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring any
remaining transmitters with you when you go to your
dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have only four transmitters
matched to it.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about three years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's probably time to change the battery.
NOTICE:
When replacing the battery, use care not to
touch any of the circuitry. Static from your
body transferred to these surfaces may
damage the transmitter.

2-42
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. 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.

2-65 Low Oil Level Light
Your engine is equipped
with an oil level monitoring
system. When the ignition
key is turned on, the
LOW OIL light will
come on briefly.
If the light does not come on briefly, have it fixed so it
will be ready to warn you if there's a problem.
If the light stays on, stop the vehicle on a level surface
and turn the engine off. Check the oil level using the
engine oil dipstick. (See ªEngine Oilº in the Index.)
If the light does not come on briefly, have the low oil
level sensor system repaired so it will be ready to warn
you if there's a problem.
The oil level monitoring system only checks oil level
during the brief period between key on and engine
crank. It does not monitor engine oil level when the
engine is running. Additionally, an oil level check is
only performed if the engine has been turned off for a
considerable period of time, allowing the oil normally in
circulation to drain back into the oil pan.
Change Oil Soon Light
The CHANGE OIL
SOON light should come
on briefly as a bulb check
when you start the engine.
If the light doesn't come on,
have it serviced.
If the CHANGE OIL SOON light comes on and stays
on after you start the engine, have the oil changed.
For additional information, see ªEngine Oil, When to
Changeº in the Index. To reset the Oil Life Monitor,
see ªEngine Oil Life Monitorº in the Index.
