Sliding Rear Window – If Equipped
A locking device in the center of the window helps to
prevent entry from the rear of the vehicle. Squeeze the
lock to release the window.
Wind Buffeting
Wind buffeting can be described as the perception of
pressure on the ears or a helicopter type sound in the
ears. Your vehicle may exhibit wind buffeting with the
windows down or partially open positions. This is a
normal occurrence and can be minimized. If the buffeting
occurs with the rear windows open, open the front and
rear windows together to minimize the buffeting. OCCUPANT RESTRAINTS
Some of the most important safety features in your
vehicle are the restraint systems. These include the front
and rear seat belts for the driver and all passengers, front
airbags for both the driver and front passenger. If you
will be carrying children too small for adult-size belts,
your seat belts also can be used to hold infant and child
restraint systems.
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.34 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!• A lap belt worn too high can increase the risk of
internal injury in a collision. The belt forces won’t
be at the strong hip and pelvic bones, but across your
abdomen. Always wear the lap belt as low as pos-
sible and keep it snug.
• A twisted belt can’t do its job as well. In a collision
it could even cut into you. Be sure the belt is straight.
If you can’t straighten a belt in your vehicle, take it
to your dealer and have it fixed.
5. Position the shoulder belt on your chest so that it is
comfortable and not resting on your neck. The retractor
will withdraw any slack in the belt. 6. To release the belt, push the red button on the buckle.
The belt will automatically retract to its stowed position.
If necessary, slide the latch plate down the webbing to
allow the belt to retract fully.
WARNING!A frayed or torn belt could rip apart in a collision
and leave you with no protection. Inspect the belt
system periodically, checking for cuts, frays, or loose
parts. Damaged parts must be replaced immediately.
Do not disassemble or modify the system. Seat belt
assemblies must be replaced after a collision if they
have been damaged (bent retractor, torn webbing,
etc.) or if the airbag deployed.40 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

NOTE: These devices are not a substitute for proper seat
belt placement by the occupant. The seat belt still must be
worn snugly and positioned properly.
The pretensioners are triggered by the airbag control
module. Like the airbags, the pretensioners are single use
items. After a collision that is severe enough to deploy
the airbags and pretensioners, both must be replaced.
Enhanced Driver Seat Belt Reminder System
(BeltAlert)
If the driver’s seat belt has not been buckled within 60
seconds of starting the vehicle and if the vehicle speed is
greater than 5 mph (8 km/h), the Enhanced Warning
System (BeltAlert) will alert the driver to buckle their seat
belt. The driver should also instruct all other occupants to
buckle their seat belts. Once the warning is triggered, the
Enhanced Warning System (BeltAlert) will continue to
chime and flash the Seat Belt Warning Light for 96
seconds or until the driver’s seat belt is buckled. The Enhanced Warning System (BeltAlert) will be reactivated
if the ignition is cycled, driver’s seat belt is unbuckled for
more than 10 seconds and the vehicle speed is greater
than 5 mph (8 km/h).
The Enhanced Warning System (BeltAlert) can be en-
abled or disabled by your authorized dealer or by
following these steps:
NOTE: The following steps must occur within the first
60 seconds of the ignition switch being turned to the ON
or START position. DaimlerChrysler does not recom-
mend deactivating the Enhanced Warning System
(BeltAlert).
1. With all doors closed and the ignition switch in any
position except On or Start, buckle the driver’s seat belt.
2. Turn the ignition switch to the ON position and wait
for the Seat Belt Warning Light to turn off.46 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!Using a seat belt extender when not needed can
increase the risk of injury in a collision. Only use the
seat belt extender when the lap belt is not long
enough when it is worn low and snug, and in the
recommended seating positions. Remove and store
the extender when not needed.
Driver And Right Front Passenger Supplemental
Restraint System (SRS)—Airbag
This vehicle may have front airbags for both the driver
and front passenger (if equipped) as a supplement to the
seat belt restraint systems. The driver’s front airbag is
mounted in the center of the steering wheel. The passen-
ger’s front airbag (if equipped) is mounted in the instru-
ment panel, above the glove compartment. The words
SRS AIRBAG are embossed on the airbag covers. These airbags are certified to the new Federal regulations
that allow less forceful deployments.
This vehicle may also be equipped without a passenger
side airbag. In this case the passenger side airbag will be
replaced with a storage bin.48 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!• Do not put anything on or around the airbag
covers or attempt to manually open them. You
may damage the airbags and you could be injured
because the airbags are not there to protect you.
These protective covers for the airbag cushions are
designed to open only when the airbags are in-
flating.
• Do not mount any aftermarket equipment such as
trailer brake controllers, snowplow controllers,
auxiliary light switches, radios, etc. on or behind
the knee bolster. Knee bolsters are designed to
work with the air bag and seat belt to protect you.
Mounting any additional equipment on or behind
the knee bolster can cause injury during a crash. Airbags inflate in moderate to high speed impacts. Along
with the seatbelts, front airbags work with the instrument
panel knee bolsters to provide improved protection for
the driver and front passenger.
The seat belts are designed to protect you in many types
of collisions. The front airbags deploy in moderate to
severe frontal collisions. In certain types of collisions, the
front airbags may be triggered. But even in collisions
where the airbags work, you need the seat belts to keep
you in the right position for the airbags to protect you
properly.
Here are some simple steps you can follow to minimize
the risk of harm from a deploying airbag.
• Children 12 years and under should ride buckled up in
a rear seat, if available.
• Infants in rear facing child restraints must NEVER
ride in the front seat of a vehicle with a passenger front THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 49

airbag unless the airbag is turned off (Standard Cab
Vehicles Only). An airbag deployment can cause se-
vere injury or death to infants in that position. See the
Passenger Airbag On/Off Switch (If Equipped) sec-
tion.
• If your vehicle does not have a rear seat, see the
Passenger Airbag On/Off Switch (If Equipped) sec-
tion.
• Children that are not big enough to properly wear the
vehicle seat belt (see section on Child Restraints)
should be secured in the rear seat in child restraints or
belt-positioning booster seats. Older children who do
not use child restraints or belt-positioning booster
seats should ride properly buckled up in the rear seat.
Never allow children to slide the shoulder belt behind
them or under their arm.
• All occupants should use their seat belts properly. • The driver and front passenger seats should be moved
back as far as practical to allow the airbag room to
inflate.
WARNING!• Relying on the airbags alone could lead to more
severe injuries in a collision. The airbags work
with your seat belt to restrain you properly. In
some collisions the airbags won’t deploy at all.
Always wear your seat belts even though you
have airbags.
• Being too close to the steering wheel or instru-
ment panel during airbag deployment could cause
serious injury. Airbags need room to inflate. Sit
back, comfortably extending your arms to reach
the steering wheel or instrument panel.50 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Airbag System Components
The airbag system consists of the following:
• Airbag Control Module
• AIRBAG Readiness Light
• Driver Airbag
• Passenger Airbag (If Equipped)
• Steering Wheel and Column
• Instrument Panel
• Crash Sensor
• Interconnecting Wiring
• Knee Impact Bolsters
• Passenger Side Frontal Airbag ON/OFF Switch (Stan-
dard Cab Vehicles Only ) (If Equipped) How The Airbag System Works
• The airbag control module determines if a frontal
collision is severe enough to require the airbags to
inflate.
• The airbag control module will not detect roll over, or
rear collisions.
• The airbag control module also monitors the readiness
of the electronic parts of the system whenever the
ignition switch is in the START or RUN positions.
These include all of the items listed above except the
knee bolsters, the instrument panel, and the steering
wheel and column. If the key is in the Off position, in
the ACC position or not in the ignition, the airbags are
not on and will not inflate
• The airbag control module also turns on the AIR BAG
light in the instrument panel for 6 to 8 seconds when
the ignition is first turned on, then turns the light off. THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 51
