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 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.

How the Airbag System Works
•
The Occupant Restraint Controller (ORC) determines
if a frontal collision is severe enough to require the
airbags to inflate. The front airbag inflators are de-
signed to provide different rates of airbag inflation
from direction provided by the ORC. The ORC will not
detect roll over. The ORC 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 steering wheel and
column, and knee bolsters. 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.
During a moderate-to-severe rear impact the ORC may
deploy the seat belt pretensioners alone. Also, the ORC turns on the AIRBAG warning
light in the instrument panel for 6 to 8 seconds
for a self-check when the ignition is first turned
on. After the self-check, the AIRBAG warning
light will turn off. If the ORC detects a malfunction in any
part of the system, it turns on the AIRBAG warning light
either momentarily or continuously. A single chime will
sound if the light comes on again after initial start up.

WARNING!
Ignoring the AIRBAG warning light in your instru-
ment panel could mean you won’t have the airbags
to protect you in a collision. If the light does not
come on, stays on after you start the vehicle, or if it
comes on as you drive, have the airbag system
checked right away.
•The Passenger Airbag Disable (PAD) Indicator Light
(If Equipped) (an amber light located in the center of
the instrument panel) tells the driver and front pas-
senger when the front passenger airbag is turned off.
The PAD Indicator lamp illuminates the words PASS
AIR BAG OFF to show that the passenger airbag will
not inflate during a collision requiring airbags. The
PAD light will illuminate when the passenger frontal
airbag has been turned off by using the manual on/off
switch (standard cab models only). See Passenger Airbag On/Off Switch – (Standard Cab Vehicles Only)
in this section for additional information.
•The
Driver and Passenger Airbag/Inflator Units are
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC detects a
collision requiring the airbags, it signals the inflator

Passenger Airbag On/Off Switch – (Standard Cab
Vehicles Only)
The passenger front airbag is to be turned off only if the
passenger:
•is an infant (less than 1 year old) who must ride in the
front seat because there is no rear seat, because the rear
seat is too small for a rear-facing infant restraint or because the infant has a medical condition which
makes it necessary for the driver to be able to see the
infant,
•is a child, age 1 to 12 who must ride in the front seat
because there is no rear seat, because there is no rear
seat position available, or because the child has a
medical condition which makes it necessary for the
driver to be able to see the child,
•has a medical condition which makes passenger airbag
inflation (deployment) a greater risk for the passenger
than the risk of hitting the dashboard (instrument
panel) or windshield in a crash.
50 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
WARNING!
Whenever an airbag is turned off, even a lap/
shoulder belted passenger may hit their head, neck,
or chest on the dashboard (instrument panel) or
windshield in a crash. This may result in serious
injury or death.
To Shut Off the Passenger Airbag (Standard Cab Ve-
hicles Only)
Place the ignition key in the Passenger Airbag On/Off
Switch, push the key in and turn clockwise, and remove
the key from the switch. This will shut off the passenger
side airbag. The “Off” light near the switch will illumi-
nate when the ignition switch is turned to the ON
position. To Turn On the Passenger Airbag (Standard Cab Ve-
hicles Only)
Place the ignition key in the Passenger Airbag On/Off
Switch, push the key in and turn counterclockwise, and
remove the key from the switch. This will turn on the
passenger airbag. The “Off” light near the switch will be
off when the ignition switch is turned to the ON position.If A Deployment Occurs
The airbag system is designed to deploy the airbags
when the impact sensors detect a moderate-to-severe
frontal collision, to help restrain the driver and front
passenger, and then immediately deflate.
NOTE:
A frontal collision that is not severe enough to
need airbag protection will not activate the system. This
does not mean something is wrong with the airbag
system.

Maintaining Your Airbag System
WARNING!
•Modifications 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.
•Do not attempt to modify any part of your advanced airbag
system. The airbag may inflate accidentally or may not function
properly if modifications are made. Take your vehicle to an
authorized dealer for any advanced airbag system service. If your
seat including your trim cover and cushion needs to be serviced
in any way (including removal or loosening/tightening of seat
attachment bolts), take the vehicle to your authorized dealer.
Only manufacturer approved seat accessories may be used. If it is
necessary to modify an advanced airbag system for persons with
disabilities, contact your authorized dealer.
•You need proper knee impact protection in a collision. Do not
mount or locate any aftermarket equipment on or behind the
knee bolsters.
•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 an airbag system.
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 5 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:
•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
for blown fuses. Refer to the label located on the inside of
the fuse block cover for the proper airbag fuses. See your
dealer if the fuse is good.
Event Data Recorder (EDR)
In the event of an airbag deployment, your vehicle is
designed to record up to 2-seconds of specific vehicle
data parameters (see the following list) in the event data
recorder prior to the moment of airbag deployment.
Please note that such data are ONLY recorded if an airbag
deploys, and are otherwise unavailable. In conjunction
with other data gathered during a complete accident
investigation, the electronic data may be used by DaimlerChrysler Corporation and others to learn more
about the possible causes of crashes and associated
injuries in order to assess and improve vehicle perfor-
mance. In addition to crash investigations initiated by
DaimlerChrysler Corporation, such investigations may
be requested by customers, insurance carriers, govern-
ment officials, and professional crash researchers, such as
those associated with universities, and with hospital and
insurance organizations.
In the event that an investigation is undertaken by
DaimlerChrysler Corporation (regardless of initiative),
the company or its designated representative will first
obtain permission of the appropriate custodial entity for
the vehicle (usually the vehicle owner or lessee) before
accessing the electronic data stored, unless ordered to
download data by a court with legal jurisdiction (i.e.,
pursuant to a warrant). A copy of the data will be
provided to the custodial entity upon request. General

one year old and weigh at least 20 lbs (9 kg). Two types
of child restraints can be used rearward-facing: infant
carriers and convertiblechild seats. Both types of
child restraints are held in the vehicle by the lap/
shoulder belt.
•The infant carrier is only used rearward-facing in the
vehicle. It is recommended for children who weigh up
to about 20 lbs (9 kg). Convertiblechild seats can be
used either rearward-facing or forward-facing in the
vehicle. Convertible child seats often have a higher
weight limit in the rearward-facing direction than
infant carriers do, so they can be used rearward-facing
by children who weigh more than 20 lbs (9 kg) but are
less than one year old.
•Rearward-facing child seats must NEVERbe used in
the front seat of a vehicle with a front passenger airbag unless the airbag is turned off. An airbag deployment
could cause severe injury or death to infants in this
position.
•Children who weigh more than 20 lbs (9 kg) and who
are older than one year can ride forward-facing in the
vehicle. Forward-facing child seats and convertible
child seats used in the forward-facing direction are for
children who weigh 20 to 40 lbs (9 to 18 kg) and who
are older than one year. These child seats are also held
in the vehicle by the lap/shoulder belt.
•The belt-positioning booster seat is for children weigh-
ing more than 40 lbs (18 kg), but who are still too small
to fit the vehicle’s seat belts properly. If the child
cannot sit with knees bent over the vehicle’s seat
cushion while the child’s back is against the seat back,
they should use a belt-positioning-booster seat. The
child and booster seat are held in the vehicle by the
lap/shoulder belt. (Some booster seats are equipped
