How the Airbag System Works
²
TheOccupant 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 cluster 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.

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:
²The airbag light does not come on or flickers during
the 6 to 8 seconds when the ignition switch is first
turned on.
²The light remains on or flickers after the 6 to 8 second
interval.
²The 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 the 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 accident, your vehicle is designed to
record up to 5-seconds of specific vehicle data parameters
(see the following list) in an event data recorder prior to
the moment of airbag deployment, and up to a quarter
second of high-speed deceleration data during and/or
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 53

after airbag deployment. EDR data are ONLY recorded if
an airbag deploys, and are otherwise unavailable.
NOTE:Under certain circumstances, EDR data may not
be recorded (e.g., loss of battery power).
In conjunction with other data gathered during a com-
plete 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 firstobtain 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
data that does not identify particular vehicles or crashes
may be released for incorporation in aggregate crash
databases, such as those maintained by the US govern-
ment and various states. Data of a potentially sensitive
nature, such as would identify a particular driver, ve-
hicle, or crash, will be treated confidentially. Confidential
data will not be disclosed by DaimlerChrysler
Corporation to any third party except when:
1. Used for research purposes, such as to match data
with a particular crash record in an aggregate database,
provided confidentiality of personal data is thereafter
preserved
54 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
There are different sizes and types of restraints for
children from newborn size to the child almost large
enough for an adult seat belt. Always check the child seat
owner's manual to ensure you have the right seat for
your child. Use the restraint that is correct for your child:
Infants and Small Children
²
Safety experts recommend that children ride
rearward-facing in the vehicle until they are at least
one year old and weigh at least 20 lbs (9 kg). Two types
of child restraints can be used rearward facing: infant
carriers and9convertible9child seats.
²The infant carrier is only used rearward-facing in the
vehicle. It is recommended for children who weigh up
to about 20 lbs (9 kg).9Convertible9child 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-facingby children who weigh more than 20 lbs (9 kg) but are
less than one year old. Both types of child restraints are
held in the vehicle by the seatbelt or the LATCH child
restraint anchorage system. (See the LATCH - Child
Seat Anchorage System section.)
²Rearward-facing child seats mustNEVERbe used in
the front seat of a vehicle with a front passenger airbag
that does not have a switch to turn the airbag Off. An
airbag deployment could cause severe injury or death
to infants in this position.
Older Children and Child Restraints
²Children 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 are
older than one year old. These child seats are also held

WARNING!
²Improper 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 ex-
actly when installing an infant or child restraint.
²A rearward facing infant restraint should only be
used in a rear seat of a vehicle that does not have
an airbag off switch. A rearward facing infant
restraint in the front seat may be struck by a
deploying passenger airbag which may cause se-
vere or fatal to the infant.
Here are some tips for getting the most out of your child
restraint:
²Before buying any restraint system, make sure that it
has a label certifying that it meets all applicable SafetyStandards. The manufacturer recommends that you
try a child restraint in the vehicle seats where you will
use it before you buy it.
²The restraint must be appropriate for your child's
weight and height. Check the label on the restraint for
weight and height limits.
²Carefully follow the instructions that come with the
restraint. If you install the restraint improperly, it may
not work when you need it.
²The Extended Cab first and Club/Crew Cab second
row outside seating positions have cinching latch
plates. These are designed to keep the lap portion tight
around the child restraint so that it is not necessary to
use a locking clip. If the seat belt has a cinching latch
plate, pulling up on the shoulder portion of the
lap/shoulder belt will tighten the belt. The cinching
latch plate will keep the belt tight, however, any seat

left/right turn signal is left on with the engine RPM
vehicle speed greater than 15 mph (24 km/h) for more
than one mile.
4. Low Fuel Warning Light
This indicator lights when the fuel gauge reads 1/8
of a tank or less. There is a pointer on the side of
this symbol that indicates the side that your fuel
filler door is located.
5. High Beam Indicator
Indicates that headlights are on high beam.
6. Seat Belt Reminder Light
This light comes on for several seconds after the
ignition is turned ON as a reminder to ªbuckle
up.º This light will remain on as long as the seat
belt remains unbuckled. If this light flashes, it indicates a
fault in the airbag system. Have the system checked by
an authorized dealer.7. Coolant Temperature Light
This light warns of an overheated engine condi-
tion. For a bulb check, this light will come on
momentarily when the ignition is turned On. If the
light turns on while driving, stop the vehicle, shift into N
(Neutral) and increase the engine speed for 2 to 3
minutes. If the temperature reading does not return to
normal, seek authorized service immediately.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature light is on,
safely pull over and stop the vehicle. Idle the vehicle
in neutral with the air conditioner turned off until
the light turns off. If the light remains on, turn the
engine off immediately, and call for service.

When replacing a blown fuse, it is important to use
only a fuse having the correct amperage rating. The
use of a fuse with a rating other than indicated may
result in a dangerous electrical system overload. If a
properly rated fuse continues to blow, it suggests a
problem in the circuit that must be corrected.
NOTE:If you are leaving your vehicle dormant for
longer than 21 days you may want to take steps to protect
your battery. You may do this by disconnecting the
battery or by disconnecting the two ignition-off draw
(I.O.D.) fuses located in the Auxiliary Power Distribution
Center (PDC) located in the engine compartment. The
I.O.D. cavities include a snap-in retainer that allows the
