How To Engage The Automatic Locking Mode
1. Buckle the combination lap and shoulder
belt.
2. Grasp the shoulder portion and pull down -
ward until the entire seat belt is extracted.
3. Allow the seat belt to retract. As the seat belt retracts, you will hear a clicking sound.
This indicates the seat belt is now in the
Automatic Locking Mode.
How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt
and allow it to retract completely to disengage
the Automatic Locking Mode and activate the
vehicle sensitive (emergency) locking mode.
Supplemental Restraint Systems (SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask an authorized
dealer.
The air bag system must be ready to protect you
in a collision. The Occupant Restraint Controller
(ORC) monitors the internal circuits and inter -
connecting wiring associated with the electrical
Air Bag System Components. Your vehicle may
be equipped with the following Air Bag System
Components:

Air Bag Warning Light
The Occupant Restraint Controller
(ORC) monitors the readiness of the
electronic parts of the air bag system
whenever the ignition switch is in the
AVV/START or MAR/ACC/ON/RUN position. If
the ignition switch is in the STOP/OFF/LOCK
position the air bag system is not on and the air
bags will not inflate.WARNING!
The seat belt assembly must be replaced if
the switchable Automatic Locking Retractor
(ALR) feature or any other seat belt function
is not working properly when checked
according to the procedures in the Service
Manual.
Failure to replace the seat belt assembly
could increase the risk of injury in colli -
sions.
Do not use the Automatic Locking Mode to
restrain occupants who are wearing the
seat belt or children who are using booster
seats. The locked mode is only used to
install rear-facing or forward-facing child
restraints that have a harness for
restraining the child.

Driver And Passenger Front Air Bag Features
The driver and passenger front air bag system is
designed to inflate based on the severity and
type of collision as determined by the Occupant
Restraint Controller (ORC), which may receive
information from the front impact sensors (if
equipped) or other system components.
Front Air Bag Operation
Front Air Bags are designed to provide addi -
tional protection by supplementing the seat
belts. Front air bags are not expected to reduce
the risk of injury in rear, side, or rollover colli -
sions. The front air bags will not deploy in all
frontal collisions, including some that may
produce substantial vehicle damage — for
example, some pole collisions, truck under -
rides, and angle offset collisions.
On the other hand, depending on the type and
location of impact, front air bags may deploy in
crashes with little vehicle front-end damage but
that produce a severe initial deceleration.
WARNING!
Being too close to the steering wheel or
instrument panel during 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
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.
Never install a rear-facing child restraint in
the front seat of a vehicle. Only use a
rear-facing child restraint in the rear seat. If
the vehicle does not have a rear seat, do
not transport a rear-facing child restraint in
that vehicle.
WARNING!
No objects should be placed over or near
the air bag on the instrument panel or
steering wheel because any such objects
could cause harm if the vehicle is in a colli -
sion severe enough to cause the air bag to
inflate.
Do not put anything on or around the air
bag covers or attempt to open them manu -
ally. You may damage the air bags and you
could be injured because the air bags may
no longer be functional. The protective
covers for the air bag cushions are
designed to open only when the air bags
are inflating.
Relying on the air bags alone could lead to
more severe injuries in a collision. The air
bags work with your seat belt to restrain you
properly. In some collisions, air bags won’t
deploy at all. Always wear your seat belts
even though you have air bags.
WARNING!

76SAFETY
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 collisions, and also are needed to help keep
you in position, away from an inflating air bag.
When the ORC detects a collision requiring the
front air bags, it signals the inflator units. A large
quantity of non-toxic gas is generated to inflate
the front air bags.
The steering wheel hub trim cover and the
upper passenger side of the instrument panel
separate and fold out of the way as the air bags
inflate to their full size. The front air bags fully
inflate in less time than it takes to blink your
eyes. The front air bags then quickly deflate
while helping to restrain the driver and front
passenger.Supplemental Side Air Bags
Supplemental Seat-Mounted Side Air Bags
(SABs)
This vehicle is equipped with Supplemental
Seat-Mounted Side Air Bags (SABs).
Supplemental Seat-Mounted Side Air Bags
(SABs) are located in the outboard side of the
front seats. The SABs are marked with “SRS
AIRBAG” or “AIRBAG” on a label or on the seat
trim on the outboard side of the seats.
The SABs may help to reduce the risk of occu -
pant injury during certain side impacts, in addi -
tion to the injury reduction potential provided by
the seat belts and body structure.

Front Supplemental Seat-Mounted Side Air Bag Label
When the SAB deploys, it opens the seam on
the outboard side of the seatback’s trim cover.
The inflating SAB deploys through the seat
seam into the space between the occupant and
the door. The SAB moves at a very high speed
and with such a high force that it could injure
occupants if they are not seated properly, or if
items are positioned in the area where the SAB
inflates. Children are at an even greater risk of
injury from a deploying air bag.
WARNING!
Do not use accessory seat covers or place
objects between you and the Side Air Bags;
the performance could be adversely affected
and/or objects could be pushed into you,
causing serious injury.

Side Impacts
The Side Air Bags are designed to activate in
certain side impacts. The Occupant Restraint
Controller (ORC) determines whether the
deployment of the Side Air Bags in a particular
impact event is appropriate, based on the
severity and type of collision. The side impact
sensors aid the ORC in determining the appro -
priate 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 inde -
pendently; a left side impact deploys the left
Side Air Bags only and a right-side impact
deploys the right Side Air Bags only. 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 side colli
-
sions, 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 front air bags
deploy.
Side Air Bags are a supplement to the seat belt
restraint system. Side Air Bags deploy in less
time than it takes to blink your eyes.
WARNING!
Occupants, including children, who are up
against or very close to Side Air Bags can be
seriously injured or killed. Occupants,
including children, should never lean on or
sleep against the door, side windows, or
area where the side air bags inflate, even if
they are in an infant or child restraint.
Seat belts (and child restraints where
appropriate) are necessary for your protec -
tion in all collisions. They also help keep
you in position, away from an inflating Side
Air Bag. To get the best protection from the
Side Air Bags, occupants must wear their
seat belts properly and sit upright with their
backs against the seats. Children must be
properly restrained in a child restraint or
booster seat that is appropriate for the size
of the child.

NOTE:
Air bag covers may not be obvious in the inte -
rior trim, but they will open during air bag
deployment. Rollover Events
Side Air Bags and seat belt pretensioners are
designed to activate in certain rollover events.
The Occupant Restraint Controller (ORC) deter
-
mines whether deployment in a particular roll-
over event is appropriate, based on the severity
and type of collision. Vehicle damage by itself is
not a good indicator of whether or not Side Air
Bags and seat belt pretensioners should have
deployed.
The Side Air Bags and seat belt pretensioners
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 experi -
ences a rollover or near rollover event, and
deployment is appropriate, the rollover sensing
system will deploy the side air bags and seat
belt pretensioners on both sides of the vehicle.
The SABICs may help reduce the risk of partial
or complete ejection of vehicle occupants
through side windows in certain rollover or side
impact events.

106STARTING AND OPERATING
ParkSense Rear Park Assist Sensors
The four ParkSense Rear Park Assist sensors,
located in the rear fascia/bumper, monitor the
area behind the vehicle that is within the
sensors’ field of view. The sensors can detect
obstacles, in the horizontal direction, from
approximately 12 inches (30 cm) up to
55 inches (140 cm) from the center of the rear
fascia/bumper and up to 24 inches (60 cm)
from the corners of the rear fascia/bumper,
depending on the location, type and orientation
of the obstacle. Rear Park Assist Sensors Location
If several obstacles are detected, the Park -
Sense Rear Park Assist system indicates the
nearest obstacle. The minimum height of a detectable obstacle
corresponds to the maximum height of an
obstacle that would clear the underside of the
vehicle during the parking maneuver.
ParkSense Rear Park Assist Alerts
If an obstacle is behind the vehicle when
REVERSE gear is engaged, an audible alert is
activated.
The tones emitted by the loudspeaker inform
the driver that the vehicle is approaching an
obstacle. The pauses between the tones are
directly proportional to the distance from the
obstacle. Pulses emitted in quick succession
indicate the presence of a very close obstacle. A
continuous tone indicates that the obstacle is
less than 12 inches (30 cm) away.

108STARTING AND OPERATING
While audible signals are emitted, the audio
system is not muted.
The audible signal is turned off immediately if
the distance increases. The tone cycle remains
constant if the distance measured by the inner
sensors is constant. If this condition occurs for
the external sensors, the signal is turned off
after three seconds (stopping warnings during
maneuvers parallel to walls).
ParkSense Rear Park Assist Failure
Indications
A malfunction of the ParkSense Rear Park
Assist sensors or system is indicated, during
REVERSE gear engagement, by the instrument
panel warning icon.
The warning icon is illuminated and a
message is displayed in the instru -
ment cluster display (if equipped).
Refer to “Warning Lights And
Messages” in “Getting To Know Your Instru -
ment Panel” for further information.
The sensors and wiring are tested continuously
when the ignition is in the MAR (ACC/ON/RUN)
position. Failures are indicated immediately if
they occur when the system is on. Even if the system is able to identify that a
specific sensor is in failure condition, the instru
-
ment cluster display shall indicate that the Park-
Sense Rear Park Assist system is unavailable,
without reference to the sensor in failure condi -
tion. If even a single sensor fails, the entire
system must be disabled. The system is turned
off automatically.
Cleaning The ParkSense System
Clean the Rear Park Assist sensors with water,
car wash soap and a soft cloth. Do not use
rough or hard cloths. In washing stations, clean
sensors quickly keeping the vapor jet/high pres -
sure washing nozzles at least 4 inches (10 cm)
from the sensors. Do not scratch or poke the
sensors. Otherwise, you could damage the
sensors.
ParkSense Rear Park Assist System Usage
Precautions
NOTE:
Ensure that the outer surface and the under -
side of the rear bumper is clean and clear of
snow, ice, mud, dirt or other obstruction to
keep the Rear Park Assist system operating
properly.
Jackhammers, large trucks, and other vibra -
tions could affect the performance of Rear
Park Assist.
Clean the Rear Park Assist sensors regularly,
taking care not to scratch or damage them.
The sensors must not be covered with ice,
snow, slush, mud, dirt or debris. Failure to do
so can result in the system not working prop -
erly. The Rear Park Assist system might not
detect an obstacle behind the fascia/
bumper, or it could provide a false indication
that an obstacle is behind the fascia/
bumper.
Objects such as bicycle carriers, etc., must
not be placed within 12 inches (30 cm) from
the rear fascia/bumper while driving the
vehicle. Failure to do so can result in the
system misinterpreting a close object as a
sensor problem, causing a failure indication
to be displayed in the instrument cluster
display.
