Advanced Front Air Bags
This vehicle has Advanced Front Air Bags for both the
driver and front passenger as a supplement to the seat
belt restraint systems. The driver ’s Advanced Front Air
Bag is mounted in the center of the steering wheel. The
passenger ’s Advanced Front Air Bag is mounted in the
instrument panel, above the glove compartment. The
words “SRS AIRBAG” or “AIRBAG” are embossed on
the air bag covers.

322 SAFETY

WARNING!
•Being too close to the steering wheel or instrument
panel during Advanced Front Air Bag deployment
could cause serious injury, including death. Air
bags need room to inflate. Sit back, comfortably
extending your arms to reach the steering wheel or
instrument panel.
• Never place a rear-facing child restraint in front of
an air bag. A deploying Passenger Advanced Front
Air Bag can cause death or serious injury to a child
12 years or younger, including a child in a rear-
facing child restraint.
• Only use a rear-facing child restraint in a vehicle
with a rear seat.
Advanced Front Air Bag Features
The Advanced Front Air Bag system has multistage
driver and front passenger air bags. This system provides output appropriate to the severity and type of collision as
determined by the Occupant Restraint Controller (ORC),
which may receive information from the front impact
sensors or other system components.
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. A low energy
output is used in less severe collisions. A higher energy
output is used for more severe collisions.
This vehicle may be equipped with driver and/or front
passenger seat track position sensors that may adjust the
inflation rate of the Advanced Front Air Bags based upon
seat position.
This vehicle may be equipped with a driver and/or front
passenger seat belt buckle switch that detects whether
the driver or front passenger seat belt is buckled. The seat
belt buckle switch may adjust the inflation rate of the
Advanced Front Air Bags.

SAFETY 323

vehicle damage — for example, some pole collisions,
truck underrides, and angle offset collisions.
On the other hand, depending on the type and location of
impact, Advanced Front Air Bags may deploy in crashes
with little vehicle front-end damage but that produce a
severe initial deceleration.
Because air bag sensors measure vehicle deceleration
over time, vehicle speed and damage by themselves are
not good indicators of whether or not an air bag should
have deployed.
Seat belts are necessary for your protection in all colli-
sions, and also are needed to help keep you in position,
away from an inflating air bag.
When the ORC detects a collision requiring the Ad-
vanced Front Air Bags, it signals the inflator units. A large
quantity of non-toxic gas is generated to inflate the
Advanced Front Air Bags.The steering wheel hub trim cover and the upper right
side of the instrument panel separate and fold out of the
way as the air bags inflate to their full size. The Advanced
Front Air Bags fully inflate in less time than it takes to
blink your eyes. The air bags then quickly deflate while
helping to restrain the driver and front passenger.
Occupant Classification System (OCS) — Front
Passenger Seat
The OCS is part of a Federally regulated safety system for
this vehicle. It is designed to provide Passenger Ad-
vanced Front Air Bag output appropriate to the occu-
pant’s seated weight, as determined by the OCS.
The Occupant Classification System (OCS) consists of the
following:
•
Occupant Restraint Controller (ORC)

SAFETY 325

•Occupant Classification Module (OCM) and Sensor
located in the front passenger seat
• Air Bag Warning Light
Occupant Classification Module (OCM) and Sensor
The Occupant Classification Module (OCM) is located
underneath the front passenger seat. The Sensor is lo-
cated beneath the passenger seat cushion foam. Any
weight on the seat will be sensed by the Sensor. The OCM
uses input from the Sensor to determine the front pas-
senger ’s most probable classification. The OCM commu-
nicates this information to the ORC. The ORC may
reduce the inflation rate of the Passenger Advanced Front
Air Bag deployment based on occupant classification. In
order for the OCS to operate as designed, it is important
for the front passenger to be seated properly and prop-
erly wearing the seat belt. The OCS will NOT prevent deployment of the Passenger
Advanced Front Air Bag. The OCS may reduce the
inflation rate of the Passenger Advanced Front Air Bag if
the OCS estimates that:
•
The front passenger seat is unoccupied or has very
light objects on it; or
• The front passenger seat is occupied by a small pas-
senger, including a child; or
• The front passenger seat is occupied by a rear-facing
child restraint; or
• The front passenger is not properly seated or his or her
weight is taken off of the seat for a period of time.

WARNING!(Continued)
properly. In some collisions, Side Air Bags won’t
deploy at all. Always wear your seat belt even
though you have Side Air Bags.
NOTE: Air bag covers may not be obvious in the interior
trim, but they will open during air bag deployment.
Side Impacts
In side impacts, the side impact sensors aid the ORC in
determining the appropriate response to impact events.
The system is calibrated to deploy the Side Air Bags on
the impact side of the vehicle during impacts that require
Side Air Bag occupant protection. In side impacts, the
Side Air Bags deploy independently; a left side impact
deploys the left Side Air Bags only and a right side
impact deploys the right Side Air Bags only. The Side Air Bags will not deploy in all side collisions,
including some collisions at certain angles, or some side
collisions that do not impact the area of the passenger
compartment. The Side Air Bags may deploy during
angled or offset frontal collisions where the Advanced
Front Air Bags deploy.
Rollover Events
Side Air Bags are designed to activate in certain rollover
events. The ORC determines whether the deployment of
the Side Air Bags in a particular rollover event is appro-
priate, based on the severity and type of collision. Vehicle
damage by itself is not a good indicator of whether or not
Side Air Bags should have deployed.
The Side Air Bags will not deploy in all rollover events.
The rollover sensing system determines if a rollover
event may be in progress and whether deployment is
appropriate. In the event the vehicle experiences a roll-
over or near rollover event, and deployment of the Side

STARTING AND OPERATING 381

To Accelerate For Passing
Press the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
To Resume Speed
To resume a previously set speed, push the RES button
and release. Resume can be used at any speed above
20 mph (32 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the CANCEL
button, or normal brake pressure while slowing the
vehicle will deactivate the Speed Control without erasing
the set speed from memory.
Pushing the ON/OFF button or turning the ignition
switch OFF erases the set speed from memory.
ADAPTIVE CRUISE CONTROL (ACC) — IF
EQUIPPED
Adaptive Cruise Control (ACC) increases the driving
convenience provided by cruise control while traveling
on highways and major roadways. However, it is not a
safety system and not designed to prevent collisions.
Speed Control function performs differently. Please
refer to the proper section within this chapter.
ACC will allow you to keep cruise control engaged in
light to moderate traffic conditions without the constant
need to reset your cruise control. ACC utilizes a radar
sensor and a forward facing camera designed to detect a
vehicle directly ahead of you.
NOTE:
•If the sensor does not detect a vehicle ahead of you,
ACC will maintain a fixed set speed.
6
STARTING AND OPERATING 409

•If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or accelerate (not to exceed the
original set speed) automatically to maintain a preset
following distance, while matching the speed of the
vehicle ahead.
The Cruise Control system has two control modes:
• Adaptive Cruise Control mode for maintaining an
appropriate distance between vehicles.
• Normal (fixed speed) electronic speed control mode
for cruising at a constant preset speed. For additional
information, refer to “Normal (Fixed Speed) Cruise
Control Mode” in this section.
NOTE: Normal (fixed speed) electronic speed control
will not react to preceding vehicles. Always be aware of
the mode selected. You can change the mode by using the Cruise Control
buttons. The two control modes function differently.
Always confirm which mode is selected.
WARNING!
•
Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driving
involvement. It is always the driver ’s responsibil-
ity to be attentive of road, traffic, and weather
conditions, vehicle speed, distance to the vehicle
ahead; and, most importantly, brake operation to
ensure safe operation of the vehicle under all road
conditions. Your complete attention is always re-
quired while driving to maintain safe control of
your vehicle. Failure to follow these warnings can
result in a collision and death or serious personal
injury.

410 STARTING AND OPERATING

To increase the distance setting, push the Distance Setting
— Increase button and release. Each time the button is
pushed, the distance setting increases by one bar (longer).To decrease the distance setting, push the Distance Set-
ting — Decrease button and release. Each time the button
is pushed, the distance setting decreases by one bar
(shorter).
If there is no vehicle ahead, the vehicle will maintain the
set speed. If a slower moving vehicle is detected in the
same lane, the EVIC/DID displays the “Sensed Vehicle
Indicator” icon, and the system adjusts vehicle speed
automatically to maintain the distance setting, regardless
of the set speed.
The vehicle will then maintain the set distance until:
•
The vehicle ahead accelerates to a speed above the set
speed.
• The vehicle ahead moves out of your lane or view of
the sensor.
• The distance setting is changed.

Display Warnings And Maintenance
“Wipe Front Radar Sensor In Front Of Vehicle”
Warning
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
warning will display and also a chime will indicate when
conditions temporarily limit system performance.
This most often occurs at times of poor visibility, such as
in snow or heavy rain. The ACC system may also become
temporarily blinded due to obstructions, such as mud,
dirt or ice. In these cases, the EVIC/DID will display
“ACC/FCW Unavailable Wipe Front Radar Sensor” and
the system will deactivate.
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
message can sometimes be displayed while driving in
highly reflective areas (i.e. tunnels with reflective tiles, or
ice and snow). The ACC system will recover after thevehicle has left these areas. Under rare conditions, when
the radar is not tracking any vehicles or objects in its path
this warning may temporarily occur.
NOTE:
If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning is active Normal (Fixed Speed) Cruise
Control is still available. For additional information refer
to “Normal (Fixed Speed) Cruise Control Mode” in this
section.
If weather conditions are not a factor, the driver should
examine the sensor. It may require cleaning or removal of
an obstruction. The sensor is located in the center of the
vehicle behind the lower grille.
To keep the ACC System operating properly, it is impor-
tant to note the following maintenance items:
• Always keep the sensor clean. Carefully wipe the
sensor lens with a soft cloth. Be cautious not to damage
the sensor lens.
