Special instructions
For your added safety, your vehicle is fitted with sophisticated electronic
controls.
Please read the sectionSupplemental restraint system (SRS)
in theSeating and Safety Restraintschapter. Failure to follow
the specific warnings and instructions could result in personal injury.
Front seat mounted rear-facing child or infant seats should
NEVERbe placed in front of an active passenger airbag.
Cell phone use
The use of Mobile Communications Equipment has become increasingly
important in the conduct of business and personal affairs. However,
drivers must not compromise their own or others’ safety when using
such equipment. Mobile Communications can enhance personal safety
and security when appropriately used, particularly in emergency
situations. Safety must be paramount when using mobile communications
equipment to avoid negating these benefits.
Mobile Communication Equipment includes, but is not limited to cellular
phones, pagers, portable email devices, in-vehicle communications
systems, telematics devices and portable two-way radios.
A driver’s first responsibility is the safe operation of the vehicle.
The most important thing you can do to prevent a crash is to
avoid distractions and pay attention to the road. Wait until it is safe to
operate Mobile Communications Equipment.
Notice to owners of diesel-powered vehicles
Read the6.0 Liter Power Stroke Direct Injection Turbo Diesel Owner’s
GuideSupplement for information regarding correct operation and
maintenance of your Diesel-powered light truck.
Notice to owners of pickup trucks and utility type vehicles
Utility vehicles have a significantly higher rollover rate than

after releasing the parking brake indicates low brake fluid level and the
brake system should be inspected immediately by your servicing
authorized dealer.
Driving a vehicle with the brake system warning light on is
dangerous. A significant decrease in braking performance may
occur. It will take you longer to stop the vehicle. Have the vehicle
checked by your authorized dealer immediately.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately. Normal
braking is still functional unless the brake warning light also is
illuminated.
Airbag readiness:If this light fails
to illuminate when ignition is turned
to ON, continues to flash or remains
on, have the system serviced
immediately. A chime will also sound when a malfunction in the
supplemental restraint system has been detected.
Safety belt:Reminds you to fasten
your safety belt. A chime will also
sound to remind you to fasten your
safety belt.
Charging system:Illuminates when
the battery is not charging properly.
Transmission Tow/Haul Feature
(automatic transmission):
Illuminates when the Tow/Haul
feature has been activated. Refer to
theDrivingchapter for transmission function and operation. If the light
flashes steadily, have the system serviced immediately, damage to the
transmission could occur.

Reasons given... Consider...
“The people I’m with don’t
wear belts”Set the example, teen deaths occur 4
times more often in vehicles with
TWO or MORE people. Children and
younger brothers/sisters imitate
behavior they see.
“I have an airbag” Airbags offer greater protection when
used with safety belts. Frontal airbags
are not designed to inflate in rear and
side crashes or rollovers.
“I’d rather be thrown clear” Not a good idea.Peoplewho are
ejected are 40 times more likely
to DIE.Safety belts help prevent
ejection, WE CAN’T “PICK OUR
CRASH”.
Do not sit on top of a buckled safety belt to avoid the
BeltMinderchime. Sitting on the safety belt will increase the
risk of injury in an accident. To disable (one-time) or deactivate the
BeltMinderfeature please follow the directions stated below.
One time disable
Any time the safety belt is buckled and then unbuckled during an
ignition ON cycle, the BeltMinderwill be disabled for that ignition
cycle only.
Deactivating/activating the BeltMinderfeature
Read Steps1-5thoroughly before proceeding with the
deactivation/activation programming procedure.
The BeltMinderfeature can be deactivated/activated by performing the
following procedure:
Before following the procedure, make sure that:
•the parking brake is set
•the gearshift is in P (Park) (automatic transmission)
•the ignition switch is in the OFF position
•all vehicle doors are closed
•the driver’s safety belt is unbuckled

Important SRS precautions
The SRS is designed to work with
the safety belt to help protect the
driver and right front passenger
from certain upper body injuries.
Airbags DO NOT inflate slowly;
there is a risk of injury from a
deploying airbag.
All occupants of the vehicle, including the driver, should always
properly wear their safety belts, even when an air bag
supplemental restraint system (SRS) is provided.
Always transport children 12 years old and under in the back
seat and always properly use appropriate child restraints.
The National Highway Traffic Safety Administration (NHTSA)
recommends a minimum distance of at least 10 inches (25 cm)
between an occupant’s chest and the driver airbag module.
Never place your arm over the air bag module as a deploying air
bag can result in serious arm fractures or other injuries.
To properly position yourself away from the airbag:
•Move your seat to the rear as far as you can while still reaching the
pedals comfortably.
•Recline the seat slightly one or two degrees from the upright position.
Do not put anything on or over the air bag module. Placing
objects on or over the air bag inflation area may cause those
objects to be propelled by the air bag into your face and torso causing
serious injury.

Do not attempt to service, repair, or modify the airbag
supplemental restraint systems or its fuses. See your authorized
dealer.
The front passenger air bag is not designed to offer protection to
an occupant in the center front seating position.
Modifying or adding equipment to the front end of the vehicle
(including frame, bumper, front end body structure and tow
hooks) may affect the performance of the airbag system, increasing the
risk of injury. Do not modify the front end of the vehicle.
Additional equipment such as snowplow equipment may effect
the performance of the airbag sensors increasing the risk of
injury. Please refer to theBody Builders Layout Bookfor instructions
about the appropriate installation of additional equipment.
Removing the blocker beam without installing snow plow
attachment hardware may effect airbag deployment in a crash.
Do not operate the truck unless either the blocker beam or snow plow
attachment hardware is installed on the vehicle.
Children and airbags
For additional important safety information, read all information on
safety restraints in this guide.
Children must always be properly restrained. Failure to follow these
instructions may increase the risk of injury in a collision.
An infant in a rear-facing seat faces a high risk of serious or fatal
injuries from a deploying passenger airbag. Rear facing infant
seats should NEVER be placed in the front seats, unless the passenger
airbag is turned off. SeePassenger airbag ON/OFF switch.

How does the airbag supplemental restraint system work?
The airbag SRS is designed to
activate when the vehicle sustains
sufficient longitudinal deceleration.
The fact that the airbags did not
inflate in a collision does not mean
that something is wrong with the
system. Rather, it means the forces
were not of the type sufficient to
cause activation. Airbags are
designed to inflate in frontal and
near-frontal collisions, not rollover,
side-impact, or rear-impacts.
The airbags inflate and deflate
rapidly upon activation. After airbag
deployment, it is normal to notice a
smoke-like, powdery residue or
smell the burnt propellant. This may
consist of cornstarch, talcum
powder (to lubricate the bag) or
sodium compounds (e.g., baking
soda) that result from the
combustion process that inflates the
airbag. Small amounts of sodium
hydroxide may be present which
may irritate the skin and eyes, but
none of the residue is toxic.
While the system is designed to help
reduce serious injuries, it may also
cause minor abrasions, swelling or temporary hearing loss. Because
airbags must inflate rapidly and with considerable force, there is the risk
of death or serious injuries such as fractures, facial and eye injuries or
internal injuries, particularly to occupants who are not properly
restrained or are otherwise out of position at the time of airbag
deployment. Thus, it is extremely important that occupants be properly
restrained as far away from the airbag module as possible while
maintaining vehicle control.
Several air bag system components get hot after inflation. Do not
touch them after inflation.
