Vehicle Modification Data Recording
Some aftermarket products may cause severe engine and/or transmission
damage; refer to the What is not covered section in The new vehicle
limited warranty for your vehicle chapter of your vehicle’s Warranty
Guide for more information. Some vehicles are equipped with
Powertrain Control Systems that can detect and store information about
vehicle modifications that increase horsepower and torque output; this
information cannot be erased and will stay in the system’s memory even
if the modification is removed. When a dealer or repair facility works on
your vehicle, it may be necessary for them to access the information in
the Powertrain Control System. This information will likely identify if any
unauthorized modifications have been made to the system and may be
used to determine if repairs will be covered by warranty.
Special instructions
For your added safety, your vehicle is fitted with sophisticated electronic
controls.
Please read the section Supplemental restraint system (SRS)
in the Seating and Safety Restraints chapter. Failure to follow
the specific warnings and instructions could result in personal injury.
Front seat mounted rear-facing child or infant seats should
NEVER be 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.

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
the Driving chapter for transmission function and operation. If the light
flashes steadily, have the system serviced immediately, damage to the
transmission could occur.
Four wheel drive low: Illuminates
when four-wheel drive low is
engaged.

Reasons given... Consider...
“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. People who 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
BeltMinder chime. Sitting on the safety belt will increase the
risk of injury in an accident. To disable (one-time) or deactivate the
BeltMinder feature 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 BeltMinder will be disabled for that ignition cycle only.
Deactivating/activating the BeltMinder feature
Read Step s1-9t horoughly before proceeding with the
deactivation/activation programming procedure.
The BeltMinder feature can be deactivated/activated by performing the
following procedure:
Before following the procedure, make sure that the following conditions
are met:
• the parking brake is set
• the gearshift is in P (Park) (automatic transmission) or the neutral
position (manual transmission)
• the ignition switch is in the OFF position
• all vehicle doors are closed
• the driver’s safety belt is unbuckled
• the parklamps/headlamps are in the OFF position (If the vehicle is
equipped with Autolamps, this will not affect the procedure)
To reduce the risk of injury, do not deactivate/activate the Belt
Minder feature while driving the vehicle.

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 the Body Builders Layout Book for 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. See Passenger 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.
