REAR SEAT REMINDER ALERT (RSRA)
RSRA alerts you through a visual and auditory
notification of the possible presence of an object,
passenger, or pet in the rear seats if a rear door
was opened up to 10 minutes before the ignition
was placed in the ON/RUN position. RSRA does not
directly detect objects, passengers, or pets in the
rear seats. When the previous conditions are met,
RSRA displays the message “Check Rear Seat” on
the instrument cluster display and sounds an
auditory alert upon the driver placing the ignition in
the OFF position to exit the vehicle.
To enable or disable RSRA, see Ú page 199.
ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
Your vehicle is equipped with an advanced
Electronic Brake Control (EBC) system. This system
includes Anti-Lock Brake System (ABS), Brake
Assist System (BAS), Electronic Brake Force
Distribution (EBD), Hill Start Assist (HSA),
Electronic Roll Mitigation (ERM), Electronic
Stability Control (ESC), and Traction Control
System (TCS). These systems work together to
enhance both vehicle stability and control in
various driving conditions.
Your vehicle may also be equipped with Trailer
Sway Control (TSC) and Hill Descent Control (HDC).
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system detects an emergency
braking situation by sensing the rate and amount
of brake application and then applies optimum
pressure to the brakes. This can help reduce
braking distances. The BAS complements the
Anti-Lock Brake System (ABS). Applying the brakes
very quickly results in the best BAS assistance. To
receive the benefit of the system, you must apply
continuous braking pressure during the stopping
sequence (do not “pump” the brakes). Do not
reduce brake pedal pressure unless braking is no
longer desired. Once the brake pedal is released,
the BAS is deactivated.
WARNING!
Before exiting a vehicle, always come to a
complete stop, then shift the automatic trans -
mission into PARK and apply the parking
brake.
Always make sure the keyless ignition node is
in the OFF position, key fob is removed from
the vehicle and vehicle is locked.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving chil -
dren in a vehicle unattended is dangerous for
a number of reasons. A child or others could
be seriously or fatally injured. Children should
be warned not to touch the parking brake,
brake pedal or the gear selector.
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat buildup
may cause serious injury or death.
WARNING!
WARNING!
The Brake Assist System (BAS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded
by prevailing road conditions. BAS cannot
prevent collisions, including those resulting from
excessive speed in turns, driving on very slippery
surfaces, or hydroplaning. The capabilities of a
BAS-equipped vehicle must never be exploited in
a reckless or dangerous manner, which could
jeopardize the user's safety or the safety of
others.

original color, and the Tire Pressure Monitoring
System Warning Light will turn off. The vehicle may
need to be driven for up to 20 minutes above
15 mph (24 km/h) in order for the TPMS to receive
this information.
NOTE:When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (28 kPa)
above the recommended cold placard pressure in
order to turn the Tire Pressure Monitoring System
Warning Light off.
Service TPMS Warning
If a system fault is detected, the Tire Pressure
Monitoring System Warning Light will flash on and
off for 75 seconds and then remain on solid. In
addition, 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 Tire Pressure
Monitoring System Warning Light will no longer
flash, and the "SERVICE TPM SYSTEM" message
will no longer display, 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.
A system fault may occur due to an incorrect TPMS
sensor location condition. When a system fault
occurs due to an incorrect TPMS sensor location,
the Tire Pressure Monitoring System Warning Light
will flash on and off for 75 seconds and then
remain on solid. The system fault will also sound a
chime. In addition, the instrument cluster will
display a “Tire Pressure Temporarily Unavailable”
message in place of the tire pressure display
screen. If the ignition switch is cycled, this
sequence will repeat, providing the system fault
still exists. If the system fault no longer exists, the
Tire Pressure Monitoring System Warning Light will
no longer flash and the tire pressure display screen
will be displayed showing the tire pressure values
in the correct locations. Vehicles With Non-Matching Full Size Spare Or
Compact Spare
The non-matching full size spare or compact
spare tire does not have a TPMS sensor. There
-
fore, the TPMS will not monitor the pressure in
the non-matching full size spare or compact
spare tire.
If you install the non-matching full size spare or
compact spare tire in place of a road tire that
has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, the
TPMS Warning Light and a “LOW TIRE” message
will remain on and a chime will sound. In addi-
tion, the graphic in the instrument cluster will
still display a pressure value in a different color
and an “Inflate to XX” message.

After driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the TPMS Warning
Light will flash on and off for 75 seconds and then
remain on solid. In addition, 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.

For each subsequent ignition switch cycle, a
chime will sound, the TPMS Warning Light will
flash on and off for 75 seconds and then remain
on solid, and 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.

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 305.
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 305.
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 Úpage 422 for customer service contact
information.
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.

Lap/Shoulder Belts
All seating positions except the Crew Cab front
center seating position have combination lap/
shoulder belts.
The seat belt webbing retractor will lock only during
very sudden stops or collisions. This feature allows
the shoulder part of the seat belt to move freely
with you under normal conditions. However, in a
collision the seat belt will lock and reduce your risk
of striking the inside of the vehicle or being thrown
out of the vehicle.
WARNING!
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, the air bags won’t
deploy at all. Always wear your seat belt even
though you have air bags.
In a collision, you and your passengers can
suffer much greater injuries if you are not
properly buckled up. You can strike the inte -
rior of your vehicle or other passengers, or you
can be thrown out of the vehicle. Always be
sure you and others in your vehicle are
buckled up properly.
It is dangerous to ride in a cargo area, inside
or outside of a vehicle. In a collision, people
riding in these areas are more likely to be seri -
ously injured or killed.
Do not allow people to ride in any area of your
vehicle that is not equipped with seats and
seat belts.

Be sure everyone in your vehicle is in a seat and
using a seat belt properly. Occupants, including
the driver, should always wear their seat belts
whether or not an air bag is also provided at
their seating position to minimize the risk of
severe injury or death in the event of a crash.

Wearing your seat belt incorrectly could make
your injuries in a collision much worse. You
might suffer internal injuries, or you could
even slide out of the seat belt. Follow these
instructions to wear your seat belt safely and
to keep your passengers safe, too.
Two people should never be belted into a
single seat belt. People belted together can
crash into one another in a collision, hurting
one another badly. Never use a lap/shoulder
belt or a lap belt for more than one person, no
matter what their size.
WARNING!WARNING!
A lap belt worn too high can increase the risk
of injury in a collision. The seat belt forces
won’t be at the strong hip and pelvic bones,
but across your abdomen. Always wear the lap
part of your seat belt as low as possible and
keep it snug.
A twisted seat belt may not protect you prop -
erly. In a collision, it could even cut into you.
Be sure the seat belt is flat against your body,
without twists. If you can’t straighten a seat
belt in your vehicle, take it to an authorized
dealer immediately and have it fixed.
A seat belt that is buckled into the wrong
buckle will not protect you properly. The lap
portion could ride too high on your body,
possibly causing internal injuries. Always
buckle your seat belt into the buckle nearest
you.
A seat belt that is too loose will not protect you
properly. In a sudden stop, you could move too
far forward, increasing the possibility of injury.
Wear your seat belt snugly.

292SAFETY
5. Position the shoulder belt across the shoulder and chest with minimal, if any slack so that it
is comfortable and not resting on your neck.
The retractor will withdraw any slack in the
shoulder belt.
6. To release the seat belt, push the red button on the buckle. The seat belt will automatically
retract to its stowed position. If necessary,
slide the latch plate down the webbing to allow
the seat belt to retract fully.
Lap/Shoulder Belt Untwisting Procedure
Use the following procedure to untwist a twisted
lap/shoulder belt.

1. Position the latch plate as close as possible to the anchor point.

2. At about 6 to 12 inches (15 to 30 cm) above the latch plate, grab and twist the seat belt
webbing 180 degrees to create a fold that
begins immediately above the latch plate.
3. Slide the latch plate upward over the folded webbing. The folded webbing must enter the
slot at the top of the latch plate.
4. Continue to slide the latch plate up until it clears the folded webbing and the seat belt is
no longer twisted.
Adjustable Upper Shoulder Belt Anchorage
In the driver and outboard front passenger seats,
the top of the shoulder belt can be adjusted
upward or downward to position the seat belt away
from your neck. Push or squeeze the anchorage
button to release the anchorage, and move it up or
down to the position that serves you best.

Adjustable Anchorage

As a guide, if you are shorter than average, you will
prefer the shoulder belt anchorage in a lower
position, and if you are taller than average, you will
prefer the shoulder belt anchorage in a higher
position. After you release the anchorage button,
try to move it up or down to make sure that it is
locked in position.
NOTE:The adjustable upper shoulder belt anchorage is
equipped with an Easy Up feature. This feature
allows the shoulder belt anchorage to be adjusted
in the upward position without pushing or
squeezing the release button. To verify the
shoulder belt anchorage is latched, pull downward
on the shoulder belt anchorage until it is locked
into position.
WARNING!
Wearing your seat belt incorrectly could make
your injuries in a collision much worse. You
might suffer internal injuries, or you could
even slide out of the seat belt. Follow these
instructions to wear your seat belt safely and
to keep your passengers safe, too.
Position the shoulder belt across the shoulder
and chest with minimal, if any slack so that it
is comfortable and not resting on your neck.
The retractor will withdraw any slack in the
shoulder belt.
Misadjustment of the seat belt could reduce
the effectiveness of the safety belt in a crash.
Always make all seat belt height adjustments
when the vehicle is stationary.

SAFETY295
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.
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 Ú page 314.
The figures below illustrate 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.
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

Supplemental Side Air Bags — If Equipped
Front and Side Impact Sensors — If Equipped
Seat Belt Pretensioners — If Equipped
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.

300SAFETY
The SABs (if equipped with SABs) may help to
reduce the risk of occupant injury during certain
side impacts, in addition to the injury reduction
potential provided by the seat belts and body
structure.
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.
Supplemental Side Air Bag Inflatable Curtains
(SABICs) — If Equipped
Your vehicle may be equipped with Supplemental
Side Air Bag Inflatable Curtains (SABICs). If your
vehicle is equipped with Supplemental Side Air Bag
Inflatable Curtains (SABICs), please refer to the
information below. Supplemental Side Air Bag Inflatable Curtains
(SABICs) are located above the side windows. The
trim covering the SABICs is labeled “SRS AIRBAG”
or “AIRBAG.”

Supplemental Side Air Bag Inflatable Curtain (SABIC) Label Location

SABICs (if equipped with SABICs) may help reduce
the risk of head and other injuries to front and rear
seat outboard occupants in certain side impacts,
in addition to the injury reduction potential
provided by the seat belts and body structure.
The SABIC deploys downward, covering the side
windows. An inflating SABIC pushes the outside
edge of the headliner out of the way and covers the
window. The SABICs inflate with enough force to
injure occupants if they are not belted and seated
properly, or if items are positioned in the area
where the SABICs inflate. Children are at an even
greater risk of injury from a deploying air bag. The SABICs (if equipped with SABICs) may help
reduce the risk of partial or complete ejection of
vehicle occupants through side windows in certain
side impact events.
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 appropriate response
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.
WARNING!
Do not mount equipment, or stack luggage or
other cargo up high enough to block the
deployment of the SABICs. The trim covering
above the side windows where the SABIC and
its deployment path are located should
remain free from any obstructions.
In order for the SABICs to work as intended, do
not install any accessory items in your vehicle
which could alter the roof. Do not add an after
-
market sunroof to your vehicle. Do not add
roof racks that require permanent attach -
ments (bolts or screws) for installation on the
vehicle roof. Do not drill into the roof of the
vehicle for any reason.
