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.
WARNING!
In a collision, you and your passengers can suffer
much greater injuries if you are not properly buckled
up. You can strike the interior 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.
Buckle up even though you are an excellent driver, even
on short trips. Someone on the road may be a poor driver
and cause a collision that includes you. This can happen
far away from home or on your own street.Research has shown that seat belts save lives, and that
they can reduce the seriousness of injuries in a collision.
Some of the worst injuries happen when people are
thrown from the vehicle. Seat belts reduce the possibility
of ejection and the risk of injury caused by striking the
inside of the vehicle.Everyonein a motor vehicle should
be belted at all times.Lap/Shoulder Belts
All seating positions except the Quad Cabtfront center
seating position have combination lap/shoulder belts.
The belt webbing retractor is designed to lock during
very sudden stops or collisions. This feature allows the
shoulder part of the belt to move freely with you under
normal conditions. But in a collision, the belt will lock
and reduce the risk of your striking the inside of the
vehicle or being thrown out.

3. When the belt is extended long enough to fit, insert the
latch plate into the buckle until you hear a ªclick.ºWARNING!
²A belt 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 belt into the buckle nearest you.
²A belt that is too loose will not protect you as well. In a
sudden stop you could move too far forward, increasing
the possibility of injury. Wear your seat belt snugly.
²A belt that is worn under your arm is very dangerous.
Your body could strike the inside surfaces of the vehicle
in a collision, increasing head and neck injury. And a belt
worn under the arm can cause internal injuries. Ribs
aren't as strong as shoulder bones. Wear the belt over your
shoulder so that your strongest bones will take the force
in a collision.
²A shoulder belt placed behind will not protect you from
injury during a collision. You are more likely to hit your
head in a collision if you do not wear your shoulder belt.
The lap and shoulder belt are meant to be used together.

Maintaining Your Airbag System
WARNING!
²Modifications to any part of the airbag system
could cause it to fail when you need it. You could
be injured if the airbag system is not there to
protect you. Do not modify the components or
wiring, including adding any kind of badges or
stickers to the steering wheel hub trim cover or the
upper right side of the instrument panel. Do not
modify the front bumper, vehicle body structure,
or add aftermarket side steps or running boards.
²You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee bolsters.
²It is dangerous to try to repair any part of the
airbag system yourself. Be sure to tell anyone who
works on your vehicle that it has an airbag system.NOTE:
Perchlorate Material ± special handling may ap-
ply, see www.dtsc.ca.gov/hazardouswaste/perchlorate
Enhanced Accident Response System
If the airbags deploy after an impact and the electrical
system remains functional, vehicles equipped with
power door locks will unlock automatically. In addition,
approximately five seconds after the vehicle has stopped
moving, the interior lights will light until the ignition
switch is turned off.
Airbag Light
You will want to have the airbags ready to
inflate for your protection in an impact. While
the airbag system is designed to be mainte-
nance free, if any of the following occurs, have
an authorized dealer service the system promptly:
²The airbag light does not come on or flickers during
the six to eight seconds when the ignition switch is
first turned ON.

²If the belt still can't be tightened, or if pulling and
pushing on the restraint loosens the belt, disconnect
the latch plate from the buckle, turn the latch plate
around, and insert the latch plate into the buckle
again. If you still can't make the child restraint secure,
try a different seating position.
²Buckle the child into the seat according to the child
restraint manufacturer's directions.
²When your child restraint is not in use, secure it in the
vehicle with the seat belt or remove it from the vehicle.
Do not leave it loose in the vehicle. In a sudden stop or
collision, it could strike the occupants or seatbacks and
cause serious personal injury.
WARNING!
Improper installation can lead to failure of an infant
or child restraint. It could come loose in a collision.
The child could be badly injured or killed. Follow
the manufacturer's directions exactly when installing
an infant or child restraint.
Lower Anchors and Tether for CHildren (LATCH)
Each vehicle is equipped with the child restraint anchor-
age system called LATCH, which stands for Lower
Anchors and Tether for CHildren. LATCH child restraint
anchorage systems are installed in the 2500/3500 Regular
Cab passenger seat position and the Quad Cabtrear seat
outboard positions. LATCH-equipped seating positions
feature both lower anchor bars, located at the back of the

can lead to tire failure. Under inflation also reduces fuel
efficiency and tire tread life, and may affect the vehicle's
handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver 's responsibility to
maintain correct tire pressure, even if under inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash forapproximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replace-
ment or alternate tires and wheels allow the TPMS to
continue to function properly.
