Read the instructions completely before attempting
to program the Universal Home Remote. Because
of the steps involved, it may be helpful to have
another person available to assist you in the
programming steps.
Keep the original hand-held transmitter for use in
other vehicles as well as for future Universal
Home Remote programming. It is also
recommended that upon the sale of the vehicle,
the programmed Universal Home Remote buttons
should be erased for security purposes. See
“Erasing Universal Home Remote Buttons” later in
this section or, for assistance, seeCustomer
Assistance Offices on page 642.
Be sure that people and objects are clear of the
garage door or gate operator you are programming.
When programming a garage door, it is advised to
park outside of the garage.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio-frequency signal.Programming Universal Home Remote

longer than 30 seconds and do not repeat
this step to program a second and/or
third hand-held transmitter to the remaining

about 1 to 3 inches (3 to 8 cm) away from the
Universal Home Remote buttons while
keeping the indicator light in view.
3. Simultaneously press and hold both the
desired Universal Home Remote button
and the hand-held transmitter button. Do not
release the buttons until Step 4 has been

{CAUTION:
If the airbag readiness light ever comes
on when you have turned off the airbag, it
means that something may be wrong with
the airbag system. The right front
passenger’s airbag could inate even
though the switch is off.
If your vehicle is a regular cab pickup and
this ever happens, do not let anyone
whom the national government has
identied as a member of a passenger
airbag risk group sit in the right front
passenger’s position (for example, do not
secure a rear-facing child restraint in your
vehicle) until you have your vehicle
serviced.
CAUTION: (Continued)
CAUTION: (Continued)
If your vehicle is an extended cab pickup
and this ever happens, do not let anyone
whom the national government has
identied as a member of the passenger
airbag risk group sit in the right front
passenger’s position (for example, do not
secure a rear-facing child restraint in the
right front passenger’s seat) until you
have your vehicle serviced.
249

Passenger Airbag Status Indicator
If your vehicle has the passenger sensing system,
your rearview mirror will have a passenger
airbag status indicator.
When the ignition key is turned to RUN or START,
the passenger airbag status indicator will light
ON and OFF, or the symbol for on and off,
for several seconds as a system check. Then,
after several more seconds, the status indicatorwill light either ON or OFF, or either the on or off
symbol to let you know the status of the right
front passenger’s frontal airbag.
Your vehicle may have a label on your sun visor
that says, “Never put a rear-facing child seat in the
front.” This is because the risk to the rear-facing
child is so great, if the airbag deploys.
{CAUTION:
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint, no
system is failsafe, and no one can
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend
that rear-facing child restraints be secured
in the rear seat, even if the airbag is off.United States
