SAFETY FEATURES
ANTI-LOCK BRAKE SYSTEM (ABS)
The ABS provides increased vehicle stability
and brake performance under most braking
conditions. The system automatically prevents
wheel lock, and enhances vehicle control during
braking.

The ABS performs a self-check cycle to ensure
that the ABS is working properly each time the
vehicle is started and driven. During this
self-check, you may hear a slight clicking sound
as well as some related motor noises.

ABS is activated during braking when the
system detects one or more wheels are
beginning to lock. Road conditions such as ice,
snow, gravel, bumps, railroad tracks, loose
debris, or panic stops may increase the
likelihood of ABS activation(s).You also may experience the following normal
characteristics when ABS activates:
The ABS motor noise or clicking sounds (you
may continue to hear for a short time after
the stop)
Brake pedal pulsations
A slight drop of the brake pedal at the end of
the stop

ABS is designed to function with the Original
Equipment Manufacturer (OEM) tires. Modification
may result in degraded ABS performance.

WARNING!
The ABS contains sophisticated electronic
equipment that may be susceptible to inter -
ference caused by improperly installed or
high output radio transmitting equipment.
This interference can cause possible loss of
anti-lock braking capability. Installation of
such equipment should be performed by
qualified professionals.

Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer.
Just press firmly on your brake pedal when you
need to slow down or stop.

The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency
beyond that afforded by the condition of the
vehicle brakes and tires or the traction
afforded.
The ABS cannot prevent collisions,
including those resulting from excessive
speed in turns, following another vehicle
too closely, or hydroplaning.
The capabilities of an ABS equipped vehicle
must never be exploited in a reckless or
dangerous manner that could jeopardize
the user’s safety or the safety of others.

Anti-Lock Brake System (ABS) Warning
Light
The yellow ABS Warning Light will turn on when
the ignition is placed in the ON/RUN mode and
may stay on for as long as four seconds.
If the ABS Warning Light remains on or comes
on while driving, it indicates that the anti-lock
portion of the brake system is not functioning
and that service is required. However, the
conventional brake system will continue to
operate normally if the ABS Warning Light is on.
If the ABS Warning Light is on, the brake system
should be serviced as soon as possible to
restore the benefits of Anti-Lock brakes. If the
ABS Warning Light does not come on when the
ignition is placed in the ON/RUN mode, have
the light repaired as soon as possible.
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.

Brake System Warning Light

The red Brake System Warning Light will turn on
when the ignition is placed in the ON/RUN mode
and may stay on for as long as four seconds.

If the Brake System Warning Light remains on or
comes on while driving, it indicates that the
brake system is not functioning properly and
that immediate service is required. If the Brake
System Warning Light does not come on when
the ignition is placed in the ON/RUN mode,
have the light repaired as soon as possible.
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.

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 Indicator 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.
Therefore, 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 addition, 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 instru -ment 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.

Once you repair or replace the original road
tire and reinstall it on the vehicle in place of
the non matching full size spare or compact
spare, the TPMS will update automatically.
In addition, the TPMS Warning Light will turn
off and the graphic in the instrument cluster
will display a new pressure value instead of
dashes (- -), as long as no tire pressure is
below the low-pressure warning limit in any of
the four active road tires. 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:
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

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 seriously 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.
WARNING! (Continued)
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!
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
properly. 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.

4. Position the lap belt so that it is snug and lies
low across your hips, below your abdomen.
To remove slack in the lap belt portion, pull
up on the shoulder belt. To loosen the lap belt
if it is too tight, tilt the latch plate and pull on
the lap belt. A snug seat belt reduces the risk
of sliding under the seat belt in a collision.
Positioning The Lap Belt

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.

298SAFETY
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 down -
ward on the shoulder belt anchorage until it is
locked into position.
First Row Center Seat Belt Operating
Instructions (Regular Cab Only)
The first row center seat belt (Regular Cab only)
features a seat belt with a mini-latch plate and
buckle, which allows the seat belt to detach
from the lower anchor when the seat is folded.
The latch plate and regular latch plate can then
be stored out of the way in the seat for added
convenience to open up utilization of the
storage areas behind the front seats when the
seat is not occupied.

1. Remove the mini-latch plate and regular latch plate from its stowed position on the
seat.

Connect Mini-Latch To Mini-Buckle Mini-Latch And Mini-Buckle Connected

2. Grasp the mini-latch plate and pull the seat belt over the seat.
3. Route the shoulder belt to the inside of the right head restraint.
4. When the seat belt is long enough to fit, insert the mini-latch plate into the
mini-buckle until you hear a “click.”
5. Sit back in seat. Slide the regular latch plate up the webbing as far as necessary to allow
the seat belt to go around your lap.
6. When the seat belt is long enough to fit, insert the latch plate into the buckle until
you hear a “click.”
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 instruc -
tions 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 with -
draw 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 adjust -
ments when the vehicle is stationary.
