The head restraints should only be removed by
qualified technicians, for service purposes only.
If any of the head restraints require removal,
see an authorized dealer.
For child restraint tethering Ú page 334.
UCONNECT VOICE RECOGNITION
INTRODUCING VOICE RECOGNITION
Start using Uconnect Voice Recognition with
these helpful quick tips. It provides the key
Voice Commands and tips you need to know to
control your vehicle’s Voice Recognition (VR)
system.

Uconnect 3 With 5-inch Display

WARNING!
All occupants, including the driver, should
not operate a vehicle or sit in a vehicle’s
seat until the head restraints are placed in
their proper positions in order to minimize
the risk of neck injury in the event of a
crash.
Head restraints should never be adjusted
while the vehicle is in motion. Driving a
vehicle with the head restraints improperly
adjusted or removed could cause serious
injury or death in the event of a collision.
WARNING!
Sitting in a seat with the head restraint in its
lowered position could result in serious injury
or death in a collision. Always make sure the
outboard head restraints are in their upright
positions when the seat is to be occupied.

Ú page 237.OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in
your vehicle are the restraint systems:
OCCUPANT RESTRAINT SYSTEMS
F
EATURES
Seat Belt Systems
Supplemental Restraint Systems (SRS) Air
Bags
Child Restraints
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.
IMPORTANT SAFETY PRECAUTIONS
Please pay close attention to the information in
this section. It tells you how to use your restraint
system properly, to keep you and your
passengers as safe as possible.
Here are some simple steps you can take to
minimize the risk of harm from a deploying air
bag:
1. Children 12 years old and under should
always ride buckled up in the rear seat of a
vehicle with a rear seat.

2. A child who is not big enough to wear the vehicle seat belt properly must be secured
in the appropriate child restraint or
belt-positioning booster seat in a rear
seating position Ú page 355.
3. If a child from 2 to 12 years old (not in a rear-facing child restraint) must ride in the
front passenger seat, move the seat as far
back as possible and use the proper child
restraint Ú page 355.
4. Never allow children to slide the shoulder belt behind them or under their arm.
5. You should read the instructions provided with your child restraint to make sure that
you are using it properly.
6. All occupants should always wear their lap and shoulder belts properly.
7. The driver and front passenger seats should be moved back as far as practical to allow
the front air bags room to inflate.

21_DT_OM_EN_USC_t.book Page 334

SAFETY335
8. Do not lean against the door or window. If
your vehicle has side air bags, and
deployment occurs, the side air bags will
inflate forcefully into the space between
occupants and the door and occupants
could be injured.
9. If the air bag system in this vehicle needs to be modified to accommodate a disabled
person, see Ú page 479 for customer
service contact information.SEAT BELT SYSTEMS
Buckle up even though you are an excellent
driver, even on short trips. Someone on the road
may be a poor driver and could cause a collision
that includes you. This can happen far away
from home or on your own street.
Research has shown that seat belts save lives,
and they can reduce the seriousness of injuries
in a collision. Some of the worst injuries happen
when people are thrown from the vehicle. Seat
belts reduce the possibility of ejection and the
risk of injury caused by striking the inside of the
vehicle. Everyone in a motor vehicle should be
belted at all times.
Enhanced Seat Belt Use Reminder System
(BeltAlert)
Driver And Passenger BeltAlert — If Equipped
BeltAlert is a feature intended to remind the
driver and outboard front seat passenger (if
equipped with outboard front passenger seat
BeltAlert) to buckle their seat belts. The
BeltAlert feature is active whenever the ignition
switch is in the START or ON/RUN position. Initial Indication
If the driver is unbuckled when the ignition
switch is first in the START or ON/RUN position,
a chime will signal for a few seconds. If the
driver or outboard front seat passenger (if
equipped with outboard front passenger seat
BeltAlert) is unbuckled when the ignition switch
is first in the START or ON/RUN position the
Seat Belt Reminder Light will turn on and
remain on until both outboard front seat belts
are buckled. The outboard front passenger seat
BeltAlert is not active when an outboard front
passenger seat is unoccupied.
BeltAlert Warning Sequence
The BeltAlert warning sequence is activated
when the vehicle is moving above a specified
vehicle speed range and the driver or outboard
front seat passenger is unbuckled (if equipped
with outboard front passenger seat BeltAlert)
(the outboard front passenger seat BeltAlert is
not active when the outboard front passenger
seat is unoccupied). The BeltAlert warning
sequence starts by blinking the Seat Belt
Reminder Light and sounding an intermittent
chime. Once the BeltAlert warning sequence
has completed, the Seat Belt Reminder Light
will remain on until the seat belts are buckled.
WARNING!
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.

Seat Belt Extender
If a seat belt is not long enough to fit properly,
even when the webbing is fully extended and the
adjustable upper shoulder belt anchorage (if
equipped) is in its lowest position, an authorized
dealer can provide you with a Seat Belt Extender.
The Seat Belt Extender should be used only if the
existing seat belt is not long enough. When the
Seat Belt Extender is not required for a different
occupant, it must be removed.
Seat Belts And Pregnant Women

Seat Belts and Pregnant Women

Seat belts must be worn by all occupants
including pregnant women: the risk of injury in
the event of an accident is reduced for the
mother and the unborn child if they are wearing
a seat belt.
Position the lap belt snug and low below the
abdomen and across the strong bones of the
hips. Place the shoulder belt across the chest
and away from the neck. Never place the
shoulder belt behind the back or under the arm.
Seat Belt Pretensioner
The front outboard seat belt system is equipped
with pretensioning devices that are designed to
remove slack from the seat belt in the event of
a collision. These devices may improve the performance of the seat belt by removing slack
from the seat belt early in a collision.
Pretensioners work for all size occupants,
including those in child restraints.
NOTE:
These devices are not a substitute for proper
seat belt placement by the occupant. The seat
belt still must be worn snugly and positioned
properly.
The pretensioners are triggered by the
Occupant Restraint Controller (ORC). Like the
air bags, the pretensioners are single use items.
A deployed pretensioner or a deployed air bag
must be replaced immediately.
Energy Management Feature
The front outboard seat belt system is equipped
with an Energy Management feature that may
help further reduce the risk of injury in the event
of a collision. The seat belt system has a
retractor assembly that is designed to release
webbing in a controlled manner.
WARNING!
ONLY use a Seat Belt Extender if it is physi
-
cally required in order to properly fit the
original seat belt system. DO NOT USE the
Seat Belt Extender if, when worn, the
distance between the front edge of the
Seat Belt Extender buckle and the center of
the occupant’s body is LESS than 6 inches.
Using a Seat Belt Extender when not
needed can increase the risk of serious
injury or death in a collision. Only use the
Seat Belt Extender when the lap belt is not
long enough and only use in the recom -
mended seating positions. Remove and
store the Seat Belt Extender when not
needed.

Switchable Automatic Locking Retractors
(ALR)
The seat belts in the passenger seating
positions are equipped with a Switchable
Automatic Locking Retractor (ALR) which is
used to secure a child restraint system
Ú page 364. The figure below illustrates the
locking feature for each seating position.

Automatic Locking Retractor — (ALR) Locations

If the passenger seating position is equipped
with an ALR and is being used for normal usage,
only pull the seat belt webbing out far enough to
comfortably wrap around the occupant’s
mid-section so as to not activate the ALR. If the
ALR is activated, you will hear a clicking sound
as the seat belt retracts. Allow the webbing to
retract completely in this case and then
carefully pull out only the amount of webbing necessary to comfortably wrap around the
occupant’s mid-section. Slide the latch plate
into the buckle until you hear a "click."
In Automatic Locking Mode, the shoulder belt is
automatically pre-locked. The seat belt will still
retract to remove any slack in the shoulder belt.
Use the Automatic Locking Mode anytime a
child restraint is installed in a seating position
that has a seat belt with this feature. Children
12 years old and under should always be
properly restrained in the rear seat of a vehicle
with a rear seat.
How To Engage The Automatic Locking Mode

1. Buckle the combination lap and shoulder
belt.

2. Grab the shoulder portion and pull downward 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.
WARNING!
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!
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.

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
interconnecting wiring associated with the
electrical Air Bag System Components. Your
vehicle may be equipped with the following Air
Bag System Components:
Air Bag System Components
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
Occupant Classification System
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
START or ON/RUN position. If the ignition switch
is in the OFF position or in the ACC position, the
air bag system is not on and the air bags will not
inflate. The ORC contains a backup power supply
system that may deploy the air bag system even
if the battery loses power or it becomes
disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light in
the instrument panel for approximately four to
eight seconds for a self-check when the ignition
switch is first in the ON/RUN position. After the
self-check, the Air Bag Warning Light will turn
off. If the ORC detects a malfunction in any part
of the system, it turns on the Air Bag Warning
Light, either momentarily or continuously. A
single chime will sound to alert you if the light
comes on again after initial startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag Warning
Light if a malfunction is detected that could
affect the air bag system. The diagnostics also
record the nature of the malfunction. While the
air bag system is designed to be maintenance
free, if any of the following occurs, have an
authorized dealer service the air bag system
immediately.
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.
