Children who are up against, or very close to,
any
air bag when it inflates can be seriously
injured. This is true even though your vehicle
has reduced-force frontal air bags. Air bags
plus lap-shoulder belts offer the best protection
for adults, but not for young children and
infants. Neither the vehicle’s safety belt system
nor
its air bag system is designed for them.
Young children and infants need the protection
that
a child restraint system can provide. Always
secure children properly in your vehicle.
To
read how, see the part of this manual called
“Children” and see the caution labels on the
sunvisors and
the right front passenger’s
safety belt.
AIR BAG
There is an air
bag readiness light
on the instrument
panel, which shows
AIR
BAG.
The system checks the air bag electrical system for
malfunctions. The light tells you
if there is an electrical
problem. See “Air Bag Readiness Light” in the Index
for more information.

Downloaded from www.Manualslib.com manuals search engine Safety Belt Extender
If the vehicle’s safety belt will fasten around you, you
should
use it.
But if a safety belt isn’t long enough to fasten, your
dealer will order you an extender. It’s free. When
you go
in to order it, take the heaviest coat you will wear, so the
extender will be long enough for you. The extender will
be just for you, and just for the seat in your vehicle that
you choose. Don’t let someone else use it, and use it
only for the seat it is made to fit. To wear it, just attach it
to the regular safety belt.
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.)
Replacing Restraint System Parts
After a Crash
If you’ve had a crash, do you need new belts?
After a very minor collision, nothing may be necessary.
But if the belts were stretched, as they would be if worn
during a more severe crash, then you need new belts.
If belts
are cut or damaged, replace them. Collision
damage also may mean you will need to have safety belt or seat parts repaired or replaced. New parts and repairs
may be necessary even
if the belt wasn’t being used at
the time of the collision.
If an air bag inflates, you’ll need to replace air bag
system parts. See the part on the air bag system earlier
in
this section.

1. From inside the vehicle, roll down the window, then get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open, lock
the vehicle using the power door lock or the remote
keyless entry transmitter and close the door. Wait
30
seconds until the SECURITY light goes off.
3. Reach in and unlock the door using the manual lock
and open the door. The horn
will sound and the
headlamps will flash.
If the alarm does not sound when it should, check to see
if the horn works. The horn fuse may be blown. To
replace the fuse, see “Fuses and Circuit Breakers” in the
Index.
If the fuse does not need to be replaced, you may
need to have your vehicle serviced.
To reduce the possibility of theft, always activate the
theft-deterrent system when leaving your vehicle.
Valet Lockout Button
Pressing the valet button
located inside the glove box
will disable the use of the
power trunk, fuel door and
garage door openers.
Pressing this button again
will make these features
reusable. Locking the
glove box with the door
key will also help to secure
your vehicle.
Note that the remote keyless entry transmitter can’t be used to open the
trunk or fuel door if the valet button
is on.

lane change.
Raise or lower the lever until the arrow starts
to flash to
signal a lane change. Hold it there until the lane change
is complete. The lever returns when it’s released.

is left on, a warning chime will sound
and the Driver Information Center (DIC) will display
TURN SIGNAL ON (after driving about a mile) to
remind you to turn it off. Arrows that
flash rapidly when signaling for a turn or
lane change may be caused by a burned out signal bulb.
Other drivers won’t see the turn signal.
Replace burned-out bulbs to help avoid possible accidents. Check the fuse (see “Fuses and Circuit
Breakers” in the Index) and for burned-out bulbs if the
arrow fails
to work when signaling a turn.

flashes rapidly for one or two seconds and then stops
flashing, the garage door opener has a rolling code
system.
In a rolling code system, the garage door
receiver must be trained to the universal transmitter.
Training a Garage Door Opener with
“Rolling Codes”
(If Equipped)
If you have not previously programmed the hand-held
transmitter to the universal transmitter, see
“Programming the Transmitter” earlier in this section. If
you have completed this programming already, you now
need to’ train the garage door opener receiver to
recognize the universal transmitter. Refer to your garage
door opener owner’s manual for the proper transmitter
training procedure for your garage door opener brand.
1. Locate the training button on the garage door opener
receiver. The exact location and color of the button
may
vary by garage door opener brand. If you have
difficulty locating the training button, refer
to your
garage door opener manual.
2. Press the training button on the garage door opener
receiver for one or
two seconds. A light indicator will
begin to flash when the receiver enters the train mode.
3. Return to the universal transmitter in your vehicle and
press the universal transmitter button you have already
programmed for
two to three seconds. Press the button
again to make sure that the universal transmitter has
been trained to the garage door opener receiver. Check that the training was successful. The receiver light
should no longer be
flashing.
The garage door opener should now recognize the
universal transmitter. You may either use the universal
transmitter or the hand-held transmitter to open the
garage door.
If after following these instructions you still have problems
training the garage door opener, consult your dealer.
Erasing Channels
To erase all three programmed channels, hold down the
two outside buttons until the red light begins to flash.
Individual channels cannot be erased, but can
be
reprogrammed using the procedure for programming the
transmitter explained earlier.
Accessories
Accessories for the universal transmitter are available
from the manufacturer of the unit. If you would like
additional information, please call
