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
or near frontal crash if the threshold conditions
for pretensioner activation are met. And, if
your vehicle has side impact rollover airbags,
safety belt pretensioners can help tighten
the safety belts in a side crash or a rollover event.
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.
Safety Belt Extender
If the vehicle’s safety belt will fasten around you,
you should use it.
But if a safety belt is not long enough, your dealer
will order you an extender. When you go in to
order it, take the heaviest coat you will wear,
so the extender will be long enough for you.
To help avoid personal injury, do not let someone
else use it, and use it only for the seat it is
made to t. The extender has been designed
for adults. Never use it for securing child seats.
To wear it, just attach it to the regular safety belt.
For more information see the instruction sheet
that comes with the extender.

In any particular crash, no one can say whether
an airbag should have inated simply because
of the damage to a vehicle or because of what the
repair costs were. For frontal airbags, ination is
determined by what the vehicle hits, the angle
of the impact, and how quickly the vehicle slows
down. For roof-mounted rollover airbags,
ination is determined by the location and
severity of the impact or a rollover event.
The airbag 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 on page 368for tips on
off-road driving.
What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag
sensing system detects that the vehicle is
in a crash. In the case of a roof-mounted rollover
airbag, the sensing system detects that the
vehicle is about to roll over or has been in a severe
frontal impact or a moderate to severe side
impact. The sensing system triggers a release of
gas from the inator, which inates the airbag.The inator, airbag, and related hardware are
all part of the airbag modules inside the steering
wheel and in the instrument panel in front of
the right front passenger. For vehicles with
roof-mounted rollover airbags, the airbag modules
are located in the ceiling of the vehicle, near
the side windows.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal
collisions, even belted occupants can contact
the steering wheel or the instrument panel.
In moderate to severe side collisions, even belted
occupants can contact the inside of the vehicle.
Airbags supplement the protection provided
by safety belts. Airbags distribute the force of the
impact more evenly over the occupant’s upper
body, stopping the occupant more gradually. But
the frontal airbags would not help you in many
types of collisions, including rollovers, rear
impacts, and many side impacts, primarily because
an occupant’s motion is not toward the airbag.
Roof-mounted rollover airbags would not help
you in many types of collisions, including many
frontal or near frontal collisions, and rear impacts.

The passenger sensing system will turn off the
right front passenger’s frontal 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 passenger’s 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
passenger’s frontal 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 airbag is off.
If you need to secure a forward-facing
child restraint in the right front seat,
always move the front passenger seat
as far back as it will go. It is better to
secure the child restraint in a rear seat.

3. Slide the new battery into the transmitter with
the positive side of the battery facing down.
Use a type CR2032 battery, or equivalent
type. Make sure the cover is on tightly,
so water will not get in.
4. Snap the front and the back of the
transmitter together.
5. Test the operation of the transmitter with
the vehicle.
Remote Vehicle Start
Your vehicle may have a remote starting feature.
This feature allows you to start the engine
from outside of the vehicle. It may also start up
the vehicle’s heating or air conditioning systems
and rear window defogger. Normal operation of the
system will return after the key is turned to the
RUN position.
If your vehicle has an automatic climate control
system, during remote start, the climate control
system will default to a heating mode during colder
outside temperatures and a cooling mode during
warmer outside temperatures. If your vehicle
does not have an automatic climate controlsystem, during remote start the climate control
system will turn on at the setting the vehicle was
set to when the vehicle was last turned off.
If your vehicle has heated seats, they will turn
on during colder outside temperatures and will shut
off when the key is turned to RUN.
Laws in some communities may restrict the use
of remote starters. For example, some laws
may require a person using the remote start to
have the vehicle in view when doing so. Check
local regulations for any requirements on remote
starting of vehicles.
Do not use the remote start feature if your vehicle
is low on fuel. Your vehicle may run out of fuel.
The RKE transmitter with the remote start
button, provides an increased range of operation.
However, the range may be less while the
vehicle is running. As a result, you may need to
be closer to your vehicle to turn it off, than
you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote
Keyless Entry (RKE) System on page 94for
additional information.

The ultrasonic sensors are not kept clean.
So, be sure to keep your vehicle’s rear
bumper free of mud, dirt, snow, ice, and
slush. For cleaning instructions, seeWashing
Your Vehicle on page 541. If the DIC still
displays the PARKING ASSIST OFF
message after cleaning the bumper and
driving forward at a speed of at least
15 mph (25 km/h), see your dealer.
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 URPA performance.
When URPA is disabled without driver
action and the driver attempts to turn
URPA back on by pressing the rear park
aid button, the indicator light will ash
for 3 seconds and then stay lit to indicate
that URPA is off.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 URPA, seeDIC Warnings and
Messages on page 267.
If the vehicle bumper is damaged, the URPA
system may not work properly. Take the
vehicle to your dealer to repair the system.

The air conditioning compressor will be on unless
the outside temperature is close to freezing.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease
the fan speed. Turn the knob all the way
counterclockwise to turn the front system off.
:(Outside Air):Press this button to turn
on the outside air mode. When this mode
is selected, air from outside the vehicle will
circulate throughout your vehicle. An indicator
light on the button will come on to let you know
that it is activated. The outside air mode can
be used with all modes, but it cannot be used
with the recirculation mode. Pressing this button
again will cancel the recirculation mode.
?(Recirculation):Press this button to turn
on the recirculation mode. When the button
is pressed, an indicator light will come on.This mode keeps outside air from entering the
vehicle. It can be used to reduce outside air
and prevent odors from entering your vehicle.
Recirculation may also help cool the air inside your
vehicle more quickly once the temperature inside
the vehicle is less than the outside temperature.
The recirculation mode cannot be used with oor,
defrost, or defogging modes. If you try to select
recirculation in one of those modes, the indicator
light will ash three times and turn off. The air
conditioning compressor will also come on when
this mode is activated. While in recirculation mode
the windows may fog when the weather is cold and
damp. To clear the fog, select either the defog or
defrost mode and increase the fan speed.
Recirculation mode can be turned off by pressing
the button again, or turning off the engine.
Temperature Control:Rotate the thumbwheels
up or down to increase or decrease the
temperature on the driver’s side or the passenger
side to the vehicle for the dual zone system.
228

#(Air Conditioning):Press this button on
the left knob to turn the air conditioning system
on or off. When A/C is pressed, an indicator
light will come on to let you know that the
air conditioning has been activated.
On hot days, open the windows to let hot inside
air escape; then close them. This helps to reduce
the time it takes for your vehicle to cool down.
It also helps the system to operate more efficiently.
The air conditioning system removes moisture
from the air, so you may sometimes notice a
small amount of water dripping underneath
your vehicle while idling or after turning off the
engine. This is normal.
Defogging and Defrosting
Fog on the inside of the 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 or frost from
your windshield. Turn the right knob clockwise
to select the defog or defrost mode.
-(Defog):The defog mode is used to clear
the windows of fog or moisture and warm
the passengers. This mode directs air to the
windshield, oor outlets, and side window vents.
When you select this mode, the system turns
off recirculation and runs the air conditioning
compressor unless the outside temperature is
close to freezing. The recirculation mode cannot
be selected while in the defog mode. Do not
drive the vehicle until all the windows are clear.
0(Defrost):The defrost mode is used to
remove fog or frost from the windshield more
quickly. This mode directs a portion of the air
to the windshield and side window vents and
some to the oor vents. In this mode, the system
will automatically force outside air into your
vehicle. The recirculation mode cannot be selected
while in the defrost mode. The air conditioning
compressor will run automatically in this setting,
unless the outside temperature is close to
freezing. Do not drive the vehicle until all the
windows are clear.
229

Automatic Operation
AUTO (Automatic):When automatic operation
is active the system will control the inside
temperature, the air delivery, and the fan speed.
Use the steps below to place the entire system
in automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will
change to show the current temperature(s)
and AUTO will be lit on the display. The
current delivery mode and fan speed will also
be displayed for approximately 5 seconds.
When AUTO is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor
will run when the outside temperature is over
about 40°F (4°C). The air inlet will normally
be set to outside air. If it is hot outside, the
air inlet may automatically switch to recirculate
inside air to help quickly cool down your
vehicle. The light on the button will illuminate
in recirculation.2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a
74°F (23°C) temperature setting and allow
about 20 minutes for the system to regulate.
Use the driver’s or passenger’s temperature
buttons to adjust the temperature setting
as necessary. If you choose the temperature
setting of 60°F (15°C), the system will
remain at the maximum cooling setting.
If you choose the temperature setting of
90°F (32°C), the system will remain at the
maximum heat setting. Choosing either
maximum setting will not cause the vehicle
to heat or cool any faster.
Be careful not to cover the solar sensor located
on the top of the instrument panel near the
windshield. This sensor regulates air temperature
based on sun load and also turns on your
headlamps. For more information on the solar
sensor, see “Sensors” later in this section.
232

To avoid blowing cold air in cold weather, the
system will delay turning on the fan until warm
air is available. The length of delay depends on
the engine coolant temperature. Pressing the
fan switch will override this delay and change
the fan to a selected speed.
O(On/Off):Press this button to turn off the
climate control system. Outside air will still enter
the vehicle, and will be directed to the oor.
This direction can be changed by pressing the
mode button. Recirculation can be selected once
you have selected vent or bi-level mode. The
temperature can also be adjusted using either
temperature button. If you adjust the air delivery
mode or temperature settings with the system
off, the display will illuminate briey to show
you the settings and then return off. Press the
on/off button or the up down arrows on the
fan switch, the defrost button, AUTO button,
or the air conditioning button to turn the system
on when it is off.
Manual Operation
You may manually adjust the air delivery mode
or fan speed.
y9z(Fan):The buttons with the fan symbols
allow you to manually adjust the fan speed.
Press the up arrow to increase fan speed and
the down arrow to decrease fan speed.
Pressing one of these buttons when the system
is off will turn the system on. Pressing one of these
buttons when in automatic control will place the
fan under manual control. The fan setting will
remain displayed and the AUTO light will turn off.
The air delivery mode will remain under
automatic control.
yNz(Mode):Press the mode up and down
buttons to manually change the direction of
the airow in your vehicle. Repeatedly press the
button until the desired mode appears on the
display. Pressing one of these buttons when the
system is off will change air delivery mode without
turning the system on. Pressing one of these
buttons when in automatic control will place the
mode under manual control.
