292SAFETY
NOTE:
It is particularly important for you to check the
tire pressure in all of the tires on your vehicle
monthly and to maintain the proper pressure.
The TPIS consists of the following components:
Receiver module
Four TPMS sensors (Single Rear Wheel
(SRW) applications)
Six TPMS sensors (Dual Rear Wheel (DRW)
applications)
Pressure display in the instrument cluster
The TPIS system will display all four (Single Rear
Wheel (SRW) applications) or six (Dual Rear
Wheel (DRW) applications) tire pressure values
in the instrument cluster display.
If a system fault is detected, the instrument
cluster will display a "SERVICE TPM SYSTEM"
message for a minimum of five seconds and
then display dashes (- -) in place of the pressure
value to indicate which sensor is not being
received. If the ignition switch is cycled, this sequence will
repeat, providing the system fault still exists. If
the system fault no longer exists, the "SERVICE
TPM SYSTEM" message will no longer be
displayed, and a pressure value will display in
place of the dashes. A system fault can occur
due to any of the following:
Signal interference due to electronic devices
or driving next to facilities emitting the same
radio frequencies as the TPMS sensors.
Installing aftermarket window tinting that
contains materials that may block radio wave
signals.
Accumulation of snow or ice around the
wheels or wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPMS
sensors.
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.

SAFETY293
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 312.
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 312.
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.
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 445 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.
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 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 — If Equipped
3500 Models Only
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.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 recommended
seating positions. Remove and store the
Seat Belt Extender when not needed.

SAFETY301
Energy Management Feature — If
Equipped
3500 Models Only
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.
Switchable Automatic Locking Retractors
(ALR) — If Equipped
The seat belts in the passenger seating
positions may be equipped with a Switchable
Automatic Locking Retractor (ALR) which is
used to secure a child restraint system
Úpage 322.
The figure below illustrates the locking feature
for each seating position.
Regular Cab Automatic Locking Retractor (ALR)
Locations
Crew Cab 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.ALR — Switchable Automatic Locking Retractor

302SAFETY
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.
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
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.
Failure to replace the seat belt assembly
could increase the risk of injury in collisions.

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.

Front Air Bags

This vehicle has front air bags and lap/shoulder
belts for both the driver and front passenger.
The front air bags are a supplement to the seat
belt restraint systems. The driver front air bag
is mounted in the center of the steering wheel.
The passenger 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.
Front Air Bag/Knee Bolster Locations

Driver And Passenger 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 (if equipped) 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 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.
1 — Driver And Passenger Front Air Bags
2 — Driver And Passenger Knee Impact Bolsters
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.
