2003 - Regal Owner Manual

To unlatch the belt, just push the button on the buckle.
The belt should go back out of the way.
Before you close the door, be sure the belt is out of the
way. If you slam the door on it, you can damage
both the belt and your vehicle.
Safety Belt Use During Pregnancy
Safety belts work for everyone, including pregnant
women. Like all occupants, they are more likely to be
seriously injured if they don’t wear safety belts.A pregnant woman should wear a lap-shoulder belt, and
the lap portion should be worn as low as possible,
below the rounding, throughout the pregnancy.
The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it’s more
likely that the fetus won’t be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is wearing them properly.

Servicing Your Air Bag-Equipped
Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your dealer and the service
manual have information about servicing your vehicle
and the air bag systems. To purchase a service manual,
seeService Publications Ordering Information on
page 7-10.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
air bag can still inflate during improper
service. You can be injured if you are close to
an air bag when it inflates. Avoid yellow
connectors. They are probably part of the air
bag system. Be sure to follow proper service
procedures, and make sure the person
performing work for you is qualified to do so.
The air bag systems do not need regular maintenance.
Restraint System Check
Checking Your Restraint Systems
Now and then, 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.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)

This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modifications to this system by other than

to your vehicle for the transmitter to work, try this:
•Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
•Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
•Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-4.
•If you are still having trouble, see your dealer or a
qualified technician for service.

alarm. The ignition must be in OFF or ACC for the
remote alarm to work. When you press the remote alarm
button the headlamps willflash, the horn will sound
repeatedly and your interior lamps will turn on, attracting
attention. The alarms will continue until one of the
following occurs:
•You press the remote alarm on the remote keyless
entry transmitter a second time,
•the ignition is moved to RUN, or
•an alarm period of about two minutes has elapsed.
Security Feedback
Security feedback provides audible and/or visible
feedback confirming that a remote keyless entry lock or
unlock command has been received and executed.
The ignition must be off for this feature to work.
You may select one of four operating modes for
reception of a lock command. You may also select one
of four operating modes for reception of an unlock
command. The selection and programming of the lock
and unlock operating modes are independent of
each other.
Programmable Modes
Your vehicle can be programmed to one of the following
modes.
Mode 1:No Verification
Mode 2:Horn Chirp only
Mode 3:Headlamps Flash only
Mode 4:Horn Chirp and Headlamps Flash
Before your vehicle was shipped from the factory, it was
programmed to Mode 3. The mode to which your
vehicle was programmed may have been changed since
it left the factory. To determine which security feedback
lock mode your vehicle is programmed to or to
program your vehicle to a different mode, do the
following:
1. Close all doors and turn the ignition key to RUN.
2. Press and hold the power door lock switch in
the lock position.
3. While holding the door lock switch in the lock
position, press and release the remote keyless entry
transmitter LOCK button. This will start the
customization mode. While in the customization
mode, the feature will sound the number of chimes
corresponding to the current lock mode. If you
do not wish to change the current mode, you can
either exit the programming mode by following
the instructions listed here or program the
next feature available on your vehicle.

2003 - Regal OM

4. Each additional press of the remote keyless entry
transmitter LOCK button will cause your vehicle to
advance the lock mode by one, starting from
the current lock mode.
5. If cycled beyond Mode 4, the vehicle will enter
Mode 1. When the door lock switch is released,
the vehicle will remain in the most recent lock mode.
The mode you selected is now set. You can either exit
the programming mode by following the previous
instructions or program the next feature available on
your vehicle.
Disconnecting the vehicle’s battery for up to a year will
not change the programmed mode for the lock and
unlock security feedback features.
Delayed Locking
Delayed locking allows the doors to be locked while the
passengers are exiting the vehicle. This feature also
allows a brief time period for you to re-enter the vehicle
after the doors have been closed and locked. Delayed
locking is user programmable for enabling or disabling
the feature.
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“Remote Keyless Entry System
Operation”earlier 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 function 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 offive seconds. During thisfive 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 previously, 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.
2-6
2003 - Regal OM

The enabled/disabled state of the delayed locking
feature will be toggled when you perform the following
sequence:
1. Close the doors.
2. Move the ignition key to the RUN position.
3. Apply your regular brakes.
4. 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 lock 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 for the delayed locking
feature.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 until a period of 40 seconds has
elapsed. If a door is opened during this period, the timed
lighting will be canceled, and the interior lamps will
remain on. Also see“Entry Lighting”underInterior
Lamps on page 3-13for more information.
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 a maximum of four
transmitters matched to it.
