or the safety belts!
With safety belts, you slow down as the vehicle does.
You get more time to stop. You stop over more distance,
and your strongest bones take the forces. That’swhy
safety belts make such good sense.
Questions and Answers About
Safety Belts
Q:Won’t I be trapped in the vehicle after an
accident if I’m wearing a safety belt?
A:Youcouldbe–whether you’re wearing a safety
belt or not. But you can unbuckle a safety belt,
even if you’re upside down. And your chance
of being conscious during and after an accident,
so youcanunbuckle and get out, ismuchgreater if
you are belted.
Q:If my vehicle has air bags, why should I have to
wear safety belts?
A:Air bags are in many vehicles today and will be in
most of them in the future. But they are
supplemental systems only; so they workwith
safety belts–not instead of them. Every air bag
system ever offered for sale has required the
use of safety belts. Even if you’re in a vehicle that
has air bags, you still have to buckle up to get
the most protection. That’s true not only in frontal
collisions, but especially in side and other
collisions.

5. To tighten the belt, feed the shoulder belt back into
the retractor while you push down on the child
restraint. If you’re using a forward-facing child
restraint, you mayfind it helpful to use your knee to
push down on the child restraint as you tighten
the belt.
6. Push and pull the child restraint in different
directions to be sure it is secure.To remove the child restraint, just unbuckle the vehicle’s
safety belt and let it go back all the way. The safety
belt will move freely again and be ready to work for an
adult or larger child passenger.
Securing a Child Restraint in a
Center Rear Seat Position
You can secure a child restraint in the center rear seat
position. There is limited space in the rear seating
area. If you want to secure a child restraint in a rear
seating position, especially in the rear center position, be
sure to study the instructions that came with your
child restraint to see if there is enough room to secure
your seat properly.

{CAUTION:
If something is between an occupant and an
air bag, the bag might not inflate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inflating air bag must be kept clear. Don’t put
anything between an occupant and an air bag,
and don’t attach or put anything on the
steering wheel hub or on or near any other air
bag covering.
When Should an Air Bag Inflate?
An air bag is designed to inflate in a moderate to severe
frontal, or near-frontal crash. The air bag will inflate
only if the impact speed is above the system’s designed
“threshold level.”
In addition, your vehicle has“dual stage”frontal air
bags, which adjust the amount of restraint according to
crash severity. For moderate frontal impacts, these
air bags inflate at a level less than full deployment.For more severe frontal impacts, full deployment occurs.
If the front of your vehicle goes straight into a wall
that doesn’t move or deform, the threshold level for the
reduced deployment is about 10 to 16 mph
(16 to 25 km/h), and the threshold level for a full
deployment is about 20 to 25 mph (32 to 40 km/h).
The threshold level can vary, however, with specific
vehicle design, so that it can be somewhat above
or below this range.
If your vehicle strikes something that will move or
deform, such as a parked car, the threshold level will be
higher. The air bag is not designed to inflate in
rollovers, rear impacts, or in many side impacts because
inflation would not help the occupant.
In any particular crash, no one can say whether an air
bag should have inflated simply because of the damage
to a vehicle or because of what the repair costs were.
Inflation is determined by the angle of the impact
and how quickly the vehicle slows down in frontal or
near-frontal impacts.
The air bag system is designed to work properly under
a wide range of conditions, including off-road usage.
Observe safe driving speeds, especially on rough
terrain. As always, wear your safety belt. See“Off-Road
Driving”in the Index for more tips on off-road driving.

Resynchronization
Resynchronization may be necessary due to the security
method used by this system. The transmitter does not
send the same signal twice to the receiver. The receiver
will not respond to a signal that has been sent previously.
This prevents anyone from recording and playing back
the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and press and hold the LOCK and UNLOCK
buttons on the transmitter at the same time for
15 seconds. The door locks should cycle to conrm
synchronization. If the locks do not cycle, see your dealer
for service.
Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers — especially children — can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
CAUTION: (Continued)
CAUTION: (Continued)
handle won’t open it. You increase the chance
of being thrown out of the vehicle in a crash if
the doors aren’t locked. So, wear safety belts
properly and lock the doors whenever you
drive.
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.
To lock and unlock your vehicle, do one of the following:
You can use the keyless entry system,
use your key, or

{CAUTION:
Leaving children in a vehicle with the windows
closed is dangerous. A child can be overcome
by the extreme heat and can suffer permanent
injuries or even death from heat stroke. Never
leave a child alone in a vehicle, especially with
the windows closed in warm or hot weather.

Sun Visors
To block out glare, you can swing down the top and
bottom visors. You can also swing the bottom visor from
side-to-side. The visors may also have an extension
that can be pulled out for additional glare protection.
Illuminated Visor Vanity Mirrors
Your vehicle may have this feature. If it does, pull the
sun visor down and lift the mirror cover to turn on
the lamps. There is a slide switch to adjust the intensity
of the lamps.
Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there are ways you
can help.
Content Theft-Deterrent
Your vehicle is equipped with a content theft-deterrent
alarm system.
With this system, the
security light on the cluster
willash as you open
the door (if your ignition is
off), to let you know
that you are activating the
system.
This message reminds you to activate the theft-deterrent
system. Here’s how to do it:
1. Open the door.
2. Lock the door with the power door lock switch or
the remote keyless entry transmitter. The security
light should come on andash. If you are using the
remote keyless entry transmitter, the door does
not need to be open.
3. Close all of the doors. The light will stopashing and
stay solid.The security light should go off after
approximately 30 seconds. The alarm is not armed
until the security light goes off. If the delayed locking
feature is active, the alarm will not activate until all
doors are closed and the security light goes off.
