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 workwithsafety 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.
Q:If I’m a good driver, and I never drive far from
home, why should I wear safety belts?
A:You may be an excellent driver, but if you’re in an
accident — even one that isn’t your fault — you and
your passengers can be hurt. Being a good driver
doesn’t protect you from things beyond your control,
such as bad drivers.
Most accidents occur within 25 miles (40 km)
of home. And the greatest number of serious
injuries and deaths occur at speeds of less than
40 mph (65 km/h).
Safety belts are for everyone.

When Should an Air Bag Inate?
The driver’s and right front passenger’s frontal air bags
are designed to inate in moderate to severe frontal
or near-frontal crashes. But they are designed to inate
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
inate 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 12 to 16 mph (19 to 26 km/h), and the threshold
level for a full deployment is about 16 to 25 mph
(26 to 40 km/h). The threshold level can vary, however,
with specic 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 driver’s and right front passenger’s frontal
air bags are not designed to inate in rollovers, rear
impacts, or in many side impacts because ination
would not help the occupant.Your vehicle may or may not have a side impact air
bag. See Air Bag Systems in the Index. Side impact air
bags are designed to inate in moderate to severe
side crashes. A side impact air bag will inate if
the crash severity is above the system’s designed
“threshold level.” The threshold level can vary with
specic vehicle design. Side impact air bags are
not designed to inate in frontal or near-frontal impacts,
rollovers or rear impacts, because ination would not
help the occupant. A side impact air bag will only deploy
on the side of the vehicle that is struck.
In any particular crash, no one can say whether an air
bag should have inated simply because of the damage
to a vehicle or because of what the repair costs were.
For frontal air bags, ination is determined by the angle
of the impact and how quickly the vehicle slows down
in frontal and near-frontal impacts. For side impact
air bags, ination is determined by the location
and severity of the impact.
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. SeeOff-Road
Driving with Your Four-Wheel-Drive Vehicle on
page 4-16for tips on off-road driving.

Doors and 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 handle will not open it. You increase
the chance of being thrown out of the
vehicle in a crash if the doors are not
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.
CAUTION: (Continued)
CAUTION: (Continued)

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.
There are several ways to lock and unlock your vehicle.
You can use the remote keyless entry system.
You can use your key to unlock your door from the
outside.

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

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 may be equipped with a content
theft-deterrent alarm system.
Here’s how to operate the system:
1. Open the door.
2. Lock the door with the power door lock switch or
the remote keyless entry transmitter. The security
light should ash.
3. Close all doors. The security light should turn off
after approximately 30 seconds. The alarm is not
armed until the security light turns off.United States

A second mirror position, seating position and adjustable
pedal position can be programmed by repeating the
procedure with a second driver and pressing button 2
for three seconds. Each time button 1 or 2 is pressed
and released while the vehicle is in PARK (P), a single
chime will sound, and the memory position will be
recalled.
If you use the unlock button on the remote keyless
entry transmitter to enter your vehicle, the preset
driver’s seat, mirror positions and adjustable pedal
position will be recalled if programmed to do so through
the Driver Information Center (DIC). The numbers on
the back of the transmitters, 1 or 2, correspond to
the numbers on the memory controls.
The seat positions, mirror positions and adjustable
pedal positions can also be recalled by placing the
key in the ignition if programmed to do so through the
Driver Information Center (DIC). SeeDIC Operation
and Displays on page 3-51.
To stop recall movement of the memory feature at any
time, press one of the power seat controls or memory
buttons.Two personalized exit positions can be set by rst
recalling the driver’s position by pressing 1 or 2, then
positioning the seat in the desired exit position for
that driver. Press and hold the button with the exit
symbol for three seconds. A double chime will sound
to let you know that the position has been stored.
With the vehicle in PARK (P), the exit position for that
driver can be recalled by pressing the exit button.
The mirrors, power lumbar, recline and adjustable
pedal positions will not be stored or recalled for the
exit positions. If no exit position is stored, the default is
all the way rearward.
Further programming for automatic seat and mirror
movement can be done through the Driver Information
Center (DIC). You may choose to either select or
not select the following:
Automatic seat, mirror movement and pedal
position when the vehicle is unlocked with the
remote keyless entry

If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once
you leave the garage, it will take about one minute for
the automatic headlamp system to change to DRL if it is
light outside. During that delay, your instrument panel
cluster may not be as bright as usual. Make sure
your instrument panel brightness control is in the full
bright position.
To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is off.
Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake,
shift out of park or turn the exterior lamp control to
the off position as described in “Exterior Lamps” listed
previously.
Lamps On Reminder
A reminder tone will sound when your headlamps or
parking lamps are manually turned on, the driver’s door
is open and your ignition is in LOCK or ACCESSORY.
To turn the tone off, turn the knob all the way
counterclockwise. In the automatic mode, the headlamps
turn off once the ignition key is in LOCK.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during the day.
DRL can be helpful in many different driving conditions,
but they can be especially helpful in the short periods
after dawn and before sunset. Fully functional daytime
running lamps are required on all vehicles rst sold
in Canada.
The DRL system will make your headlamps come on
at reduced brightness when the following conditions
are met:
The ignition is on
the exterior lamps knob is in automatic
headlamp mode
the light sensor detects daytime light
the transmission is not in PARK (P)
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won’t be
on. The instrument panel won’t be lit up either.
When it begins to get dark, the headlamps will
automatically switch from DRL to the regular headlamps.
