Window Airbags Supplemental Restraint System
(SRS)—If Equipped
The window airbag control module determines if a side
collision is severe enough to require the side airbags to
inflate. The window airbag control module will not
detect roll over, front or rear collisions.
The airbag control module monitors the readiness of the
electronic parts of the system whenever the ignition
switch is in the STARTorRUN positions. These
include all of the items listed above. The airbag control
module also turns on the AIRBAG light in the instrument
panel for 6 to 8 seconds when the ignition is first turned
on as a diagnostic or system check, then turns the light
off. If it detects a malfunction in any part of the system,
it turns on the light either momentarily or continuously.
The side (window) impact SRS Airbags are designed to
activate only in certain side collisions. When the airbag
control module detects a collision requiring the window bags to inflate, it signals the inflators on the crash side of
the vehicle. A quantity of nontoxic gas is generated to
inflate the window bag. The inflating window bag
pushes the side pillar molding out of the way and covers
the window. The airbag inflates in about 30 milliseconds
(about one-quarter of the time it takes to blink your eyes)
with enough force to injure you if you are not belted and
seated properly, or if items are positioned in the area
where the window bag inflates. This especially applies to
children. The window bag is only about 3
12inches (8.9
cm) thick when it is inflated.
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 10 seconds after the vehicle has stopped
moving, the interior lights will light until the ignition
switch is turned off.
54 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Maintaining Your Airbag Systems
WARNING!
•Modifications to any part of the airbag system
could cause it to fail when you need it. You could
be injured because the airbags are 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 struc-
ture, or frame.
•You need proper knee impact protection in a
collision. Do not mount or locate any aftermarket
equipment on or behind the knee bolster.
•It 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 airbags.
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:
•The airbag light does not come on or flickers during
the 6 to 8 seconds when the ignition switch is first
turned on.
•The light remains on or flickers after the 6 to 8 second
interval.
•The light flickers or comes on and remains on while
driving.
NOTE: If the speedometer, tachometer or any engine
related gauges are not working, the airbag control mod-
ule may also be disabled. The airbags may not be ready
to inflate for your protection. Promptly check fuse block

•The lap portion should be low on the hips and as snug
as possible.
•Check belt fit periodically. A child’s squirming or
slouching can move the belt out of position.
If the shoulder belt contacts the face or neck, move the
child closer to the center of the vehicle. Never allow a
child to put the shoulder belt under an arm or behind
their back.
NEW ENGINE BREAK-IN
Your Cummins 24 Valve Turbo Diesel engine does not
require a break-in period due to its construction. Normal
operation is allowed, provided the following recommen-
dations are followed:
NOTE: Light duty operation such as light trailer towing
or no load operation, will extend the time before the
engine is at full efficiency. Reduced fuel economy and
power may be seen at this time.
•Warm up the engine before placing it under load.
•Do not operate the engine at idle for prolonged
periods.
•Use the appropriate transmission gear to prevent
engine lugging.
•Observe vehicle oil pressure and temperature indica-
tors.
•Check the coolant and oil levels frequently.
•Vary throttle position at highway speeds when carry-
ing or towing significant weight.
Because of the construction of the Cummins Diesel
engine, engine run-in is enhanced by loaded operating
conditions which allow the engine parts to achieve final
finish and fit during the first 6,000 miles (10 000 km).

CAUTION!
•During the first 500 miles (805 km) your new
vehicle is driven, do not tow a trailer. Doing so
may damage your vehicle.
•Limit your speed to 50 mph (80 km/h) during the
first 500 miles (805 km) of towing.
SAFETY TIPS
Transporting Passengers
This vehicle is designed to carry passengers in the cab
only. For safety reasons, NEVER TRANSPORT PASSEN-
GERS IN THE CARGO AREA.
WARNING!
It is extremely 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.
Lock Your Vehicle
Always remove the keys from the ignition and lock all
doors when leaving the vehicle unattended, even in your
own driveway or garage. Try to park your vehicle in a
well-lighted area and never invite theft by leaving ar-
ticles of value exposed.
72 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Safety Checks You Should Make Inside The
Vehicle
Heater Defroster Ducts
Inspect the heater defroster ducts for proper operation.
Check for proper air flow through all defroster ducts. If
there are any question regarding the operation of your
heater defroster ducts, have the system checked by an
authorized dealer
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Seat belt assemblies must be replaced after an accident if
they have been damaged (bent retractor, torn webbing,
etc.) or if the front airbags have deployed. If there is any
question regarding belt or retractor condition, replace the
belt.
Airbag Light
The light should come on and remain on for 6 to 8
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see your
authorized dealer. If the light stays on, flickers or comes
on while driving, have the system checked by an autho-
rized dealer. If there is a problem with the airbag light the
seatbelt light will flash.
Safety Checks You Should Make Outside The
Vehicle
Tires
Examine tires for tread wear or uneven wear patterns.
Check for stones, nails, glass or other objects lodged in
the tread.
Inspect for tread cuts or sidewall cracks. Check wheel
nuts for tightness and tires for proper pressure.
74 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Lights
Check the operation of all exterior lights. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for positive closing, latching and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
water, oil, or other fluid leaks. Also, if fuel fumes are
detected the cause should be located and corrected.
