4. Buckle, position, and release the safety belt
as described inRear Seat Passengers on
page 36. Make sure that the shoulder
belt crosses the shoulder.
To remove and store the comfort guide, squeeze
the belt edges together so that you can take
them out of the guide. Slide the guide into
its storage pocket on the top of the seatback.
Safety Belt Pretensioners
Your vehicle has safety belt pretensioners for the
driver and right front passenger. Although you
cannot see them, they are part of the safety belt
assembly. They help tighten the safety belts during
the early stages of a moderate to severe frontal
and near frontal crash if the threshold conditions
for pretensioner activation are met. And, if
your vehicle has side impact airbags, safety belt
pretensioners can help tighten the safety belts in a
side crash.
Pretensioners work only once. If they activate in a
crash, you will need to get new ones, and
probably other new parts for your safety belt
system. SeeReplacing Restraint System Parts
After a Crash on page 89.

The passenger sensing system will turn off the
right front passenger’s frontal airbag and
seat-mounted side impact airbag under certain
conditions. The driver’s airbags are not part of the
passenger sensing system.
The passenger sensing system works with sensors
that are part of the right front passenger’s seat and
safety belt. The sensors are designed to detect the
presence of a properly-seated occupant and
determine if the right front passenger’s frontal
airbag and seat-mounted side impact airbag should
be enabled (may inate) or not.
Accident statistics show that children are safer if
they are restrained in the rear rather than the front
seat. We recommend that child restraints be
secured in a rear seat, including an infant riding in
a rear-facing infant seat, a child riding in a
forward-facing child seat and an older child riding
in a booster seat.
Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun
visor 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:
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag.
Even though the passenger sensing
system is designed to turn off the right
front passenger’s frontal and
seat-mounted side impact airbag if the
system detects a rear-facing child
restraint, no system is fail-safe, 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 airbags are off.
CAUTION: (Continued)

The headlamp stalk is moved forward to the
high-beam position or the ash-to-pass feature
is used. SeeHeadlamp High/Low-Beam
Changer on page 167andFlash-to-Pass
on page 172.
When either of these conditions occur, the
IntelliBeam™ feature is disabled and the
IntelliBeam™ light in the mirror turns off until
the high-beam stalk is returned to the neutral
position.
If IntelliBeam™ was using low-beams prior
to this action, the IntelliBeam™ feature is
temporarily disabled until the stalk is returned
to the neutral position.
The exterior lamp control is turned to any
setting except AUTO.
When this occurs, IntelliBeam™ is disabled
until the control is turned back to the AUTO
position.
The IntelliBeam™ system is turned off at the
inside rearview mirror.IntelliBeam™ might not turn off the high-beams if
the system cannot detect other vehicle’s lamps
because of any of the following:
The other vehicle’s lamp(s) are missing,
damaged, obstructed from view, or otherwise
undetected.
The other vehicle’s lamp(s) are covered with
dirt, snow, and/or road spray.
The other vehicle’s lamp(s) cannot be detected
due to dense exhaust, smoke, fog, snow, road
spray, mist, or other airborne obstructions.
Your vehicle’s windshield is dirty, cracked, or
obstructed by something that blocks the view
of the IntelliBeam™ light sensor.
Your vehicle’s windshield is covered with ice,
dirt, haze, or other obstructions.
Your vehicle is loaded such that the front
end of the vehicle points upward, causing the
IntelliBeam™ sensor to aim high and not detect
headlamps and taillamps.
You are driving on winding or hilly roads.
You might need to manually disable or cancel the
high-beam headlamps by turning the low-beam
headlamps on, if any of the above conditions exist.

A bicycle or an object is attached to the front
bumper during your last drive when you turned
off the vehicle. If the attached objects are
removed from your vehicle before the start of
your next drive, the system will return to normal
unless an object is detected when the vehicle is
shifted out of park. If this occurs, UFRPA will
return to normal operation when the vehicle is
driven forward above 15 mph (25 km/h).
The ultrasonic sensors are not kept clean.
So be sure to keep your vehicle’s front and rear
bumpers free of mud, dirt, snow, ice and slush.
For cleaning instructions, seeWashing Your
Vehicle on page 444. If after cleaning the front
and rear bumpers and driving forward at a
speed of at least 15 mph (25 km/h), the DIC
displays the PARKING ASSIST OFF message,
see your dealer/retailer.
Other conditions that may affect system
performance include vibrations from a
jackhammer or the compression of air
brakes on a very large truck or other
mechanical devices that interfere with
UFRPA performance.
When UFRPA is disabled without driver action
and the driver attempts to turn UFRPA back
on using the Driver Information Center (DIC),
the PARKING ASSIST ON option will not be
selectable if the necessary conditions stated
above for normal system operation are not met.
As always, drivers should use care when backing
up a vehicle. Always look behind you, being
sure to check for other vehicles, obstructions
and blind spots.
For Driver Information Center messages related
to UFRPA, seeDIC Warnings and Messages
on page 246.
If the bumper is damaged, your UFRPA system
may not work properly. Take the vehicle to
your dealer/retailer to repair the system.

Analog Clock
The analog clock is located on the instrument
panel above the radio. The clock is not connected
with any other vehicle system and runs by
itself. To adjust the clock, do the following:
1. Locate the adjustment button directly below
the clock face.
2. Push and hold the adjustment button to
advance the clock hands. Holding the
button down will cause the clock to advance
faster. Release the buttonbeforeyou get
to the desired time.
3. Push and release the button to increase the
time by one minute increments until the
desired time is reached.
Climate Controls
Dual Climate Control System
With this system you can control the heating,
cooling, and ventilation for the vehicle.
To avoid window fogging on rainy and humid
days at temperatures above freezing, run the
air conditioning compressor. Also, it is best
to avoid the use of recirculation mode except
when maximum air conditioning performance
is needed for a short amount of time to avoid
exterior odors and fogging.
Dual Climate Control System
210

After the vehicle is started, the display will
show the interior temperature settings and the
outside temperature.
If the AUTO position is selected on the fan or mode
control, the system will automatically control the air
conditioning compressor. The A/C compressor will
run automatically even at cool outside temperatures
in order to dehumidify the air. The A/C indicator
light will be lit when the system is operating
automatically, even at near freezing outside
temperatures. Press the A/C button on the fan
control to turn off the A/C. For improved window
clearing performance in defog or defrost modes,
the A/C compressor will run automatically.
h(AUTO RECIRCULATION):If the AUTO
position is selected on either the fan or mode
control, the system will automatically control the air
inlet to supply fresh outside air or recirculate the
interior air to cool the car faster. The indicator light
on the recirculation button will light whenever the
system switches to recirculation. You may force
outside air by pressing the recirculation button
when the light is lit. For vehicles without rear climate
controls, press the outside air button to force
outside air. The next time AUTO fan or mode is
selected, the air inlet will reset back to AUTO
operation.
Manual Operation
9(Fan):Turn the left control either to the left or
right to adjust the fan speed. Turning this control
completely counterclockwise will turn on the
automatic fan operation. Turning this control to the
“O” position will turn the climate control system off.
If the airow seems low when the fan speed is at
the highest setting, the passenger compartment air
lter may need to be replaced. SeePassenger
Compartment Air Filter on page 220.
9(Off):Turn the left control to this position to
turn the entire climate control system off.
To change the current mode, select one of the
following positions using the right control:
AUTO:Turn the control to this position to turn on
the automatic delivery mode operation.
F(Vent):Turn the control to this mode to direct
air to the instrument panel outlets.
*(Bi-Level):Turn the control to this mode to
direct approximately half of the air to the instrument
panel outlets and most of the remaining air to the
oor outlets. In automatic operation, cooler air is
directed to the upper outlets and warmer air to the
oor outlets.
212

AUX:If your vehicle has a rear climate control
system, press this button to turn the rear climate
control fan on for automatic operation. After
the AUX button is pressed, the indicator light
will come on. Press the button again to turn the
auxiliary fan off. SeeRear Climate Control System
on page 218.
#(Air Conditioning):Press the center of the
left control to override the automatic system
and turn the air conditioning system on or off.
When in AUTO, the air conditioning compressor
will come on automatically, as necessary.
The air conditioning system removes moisture from
the air, so you may notice a small amount of water
dripping underneath your vehicle while idling or
after turning off the engine. This is normal.
Sensors
The solar sensor, located in the defrost grille,
middle of the instrument panel, monitors the solar
radiation. Do not cover the solar sensor or the
system will not work properly.
214

Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate control
system is used properly. There are two modes to
clear fog from your windshield. Use the oor/defog
mode to clear the windows of fog or moisture and
warm the passengers. Use the defrost mode to
remove fog or frost from the windshield more
quickly.
W(Floor/Defog):Turn the control to this mode
to direct approximately half of the air to the
oor outlets and the remaining air is directed to
the side window outlets and to the windshield.
When you select this mode, the system turns
off recirculation and runs the air conditioning
compressor unless the outside temperature is
at or below freezing. The recirculation mode
cannot be selected while in the oor/defog mode.
0(Defrost):Turn the control to this mode to
direct most of the air to the windshield and the
side window outlets. In this mode, the system will
automatically turn off recirculation and run the
air conditioning compressor, unless the outside
temperature is at or below freezing. Recirculation
cannot be selected while in the defrost mode.
Do not drive the vehicle until all the windows
are clear.
For professional vehicles, air will be allowed to
ow through the rear outlets. For quicker defrost,
press the AUX button on the front climate
control system so that the light is not lit.
216

This light should come on, as a check to show
you it is working, when the ignition is on and
the engine is not running. If the light does
not come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and may damage the emission
control system on your vehicle. Diagnosis
and service may be required.
Light On Steady— An emission control
system malfunction has been detected on
your vehicle. Diagnosis and service may be
required.
If the Light Is Flashing
The following may prevent more serious damage
to your vehicle:
Reducing vehicle speed
Avoiding hard accelerations
Avoiding steep uphill grades
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possibleIf the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, when it is safe to do
so, stop the vehicle. Find a safe place to park your
vehicle. Turn the key off, wait at least 10 seconds
and restart the engine. If the light remains on
steady, see “If the Light Is On Steady” following.
If the light is still ashing, follow the previous steps,
and see your dealer for service as soon as
possible.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. SeeFilling the Tank on page 358.
The diagnostic system can determine if the fuel cap
has been left off or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into
the atmosphere. A few driving trips with the cap
properly installed should turn the light off.
