Airbag Warning Light
You will want to have the airbag system ready to inflate
for your protection in an impact. The airbag system is
designed to be maintenance free. If any of the following
occurs, have an authorized dealer service the system
promptly:
•Does not come on during the six to eight seconds after
the ignition switch is first turned on.
•Remains on after the six to eight second interval.
•Comes on for any period of time while driving.
Event Data Recorder (EDR)
In the event of an accident, your vehicle is designed to
record up to five seconds of specific vehicle data param-
eters (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 after airbag deployment or near-deployment.
EDR data are ONLY recorded if an airbag deploys, or
nearly 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.
60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 leasee) 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 U.S. 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
2. Used in defense of litigation involving a
DaimlerChrysler Corporation product
3. Requested by police under a legal warrant
4. Otherwise required by law
Data Parameters that May Be Recorded:
•Diagnostic trouble code(s) and warning lamp status
for electronically-controlled safety systems, including
the airbag system
•Airbag disable lamp status (if equipped)
•Time
of airbag deployment (in terms of ignition
cycles and vehicle mileage)

Child Restraint
Everyone in your vehicle needs to be buckled up at all
times — babies and children, too. Every state in the
United States and all Canadian provinces require that
small children ride in proper restraint systems. This is the
law, and you can be prosecuted for ignoring it.
Children 12 years and under should ride properly buck-
led up in a rear seat, if available. According to crash
statistics, children are safer when properly restrained in
the rear seats, rather than in the front.
There are different sizes and types of restraints for
children from newborn size to the child almost large
enough for an adult safety belt. Always check the child
seat owner’s manual to ensure you have the correct seat
for your child. Use the restraint that is correct for your
child.
62 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
In a collision, an unrestrained child, even a tiny baby,
can become a missile inside the vehicle. The force
required to hold even an infant on your lap could
become so great that you could not hold the child, no
matter how strong you are. The child and others
could be badly injured. Any child riding in your
vehicle should be in a proper restraint for the child’s
size.
Infants and Child Restraints
•
Safety experts recommend that children ride
rearward-facing in the vehicle until they are at least
one-year oldandweigh at least 20 lbs (9 kg). Two
types of child restraints can be used rearward-facing:
infant carriers and “convertible” child seats.
•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). “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. Both types of
child restraints are held in the vehicle by the lap/
shoulder belt or the LATCH child restraint anchorage
system (Refer to LATCH — Child Seat Anchorage
System in this section.)
•Rearward-facing child seats must NEVERbe used in
the front seat of a vehicle with the front passenger
airbag unless the airbag is turned off. An airbag
deployment could cause severe injury or death to
infants in this position.

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 ex-
actly when installing an infant or child restraint.
•A rearward facing infant restraint should only be
used in a rear seat. A rearward facing infant
restraint in the front seat may be struck by a
deploying passenger airbag which may cause se-
vere or fatal injury to the infant.
Here are some tips for getting the most out of your child
restraint:
•Before buying any restraint system, make sure that it
has a label certifying that it meets all applicable Safety Standards. The manufacturer also recommends that
you try a child restraint in the vehicle seats where you
will use it before you buy it.
•The restraint must be appropriate for your child’s
weight and height. Check the label on the restraint for
weight and height limits.
•Carefully follow the instructions that come with the
restraint. If you install the restraint improperly, it may
not work when you need it.
•All seating positions (except for driver) have a auto-
matic locking retractor identified by a distinctive label.
The seat belts are designed to keep the lap portion
tight around the child restraint so that it is not
necessary to use a locking clip. For the seat belt with
the automatic locking retractor, pull the belt from the
retractor until there is enough to allow you to pass
through the child restraint and slide the latch plate
into the buckle. Then, pull the belt until it is fully
64 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

extracted from the retractor. Allow the belt to return to
the retractor, pulling on the excess webbing to tighten
the lap portion about the child restraint. For additional
information, refer toAutomatic Locking Mode ear-
lier in this section.
•In the rear seat, you may have trouble tightening the
lap/shoulder belt on the child restraint because the
buckle or latch plate is too close to the belt path
opening on the restraint. Disconnect the latch plate
from the buckle and twist the short buckle-end belt
several times to shorten it. Insert the latch plate into
the buckle with the release button facing out.
•If the belt still cannot be tightened, or if pulling and
pushing on the restraint loosens the belt, disconnect
the latch plate from the buckle, turn the buckle
around, and insert the latch plate into the buckle
again. If you still cannot make the child restraint
secure, try a different seating position.
•Buckle the child into the restraint exactly as the
manufacturer’s instructions tell you.
•When 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.
NOTE: For additional information refer to
www.seatcheck.org or call 1-866-SEATCHECK.
Older Children and Child Restraints
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 chil-
dren 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 or the LATCH child
restraint anchorage system (Refer to LATCH — Child
Seat Anchorage System in this section).
The belt-positioning booster seat is for children weighing
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 seatback, they should use a
belt-positioning booster seat. The child and belt-
positioning booster seat are held in the vehicle by the
lap/shoulder belt.
Children Too Large for Booster Seats
Children who are large enough to wear the shoulder belt
comfortably, and whose legs are long enough to bend
over the front of the seat when their back is against the
seatback, should use the lap/shoulder belt in a rear seat.
•Make sure that the child is upright in the seat.
•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
the back.
Automatic-Locking Retractor (ALR)
To operate the switchable retractor, pull the belt from the
retractor until there is enough to allow you to pass
through the child restraint and slide the latch plate into
the buckle. Then pull on the belt until it is fully extended
from the retractor. Allow the belt to return into the
retractor, pulling on the excess webbing to tighten the lap
portion about the child restraint. Follow the instructions
of the child restraint manufacture.
66 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

NOTE:To reset this feature you must let all of the belt
webbing return into the retractor. You will not be able to
pull out more webbing until all of the webbing has been
returned back into the retractor.
Installing the Child Restraint System
We urge you to carefully follow the directions of the
manufacturer when installing your child restraint. Many,
but not all, restraint systems will be equipped with
separate straps on each side, with each having a hook or
connector for attachment to the lower anchorage, and a
means for adjusting the tension of the strap. Forward-
facing toddler restraints and some rearward-facing infant
restraints will also be equipped with a tether strap having
a hook for attachment to the tether strap anchorage, and
a means for adjusting the tension of the strap.
In general, you will first loosen the adjusters on the lower
and tether straps so that you can more easily attach the
hook or connector to the lower and tether anchorages. The tether strap should be routed under the center of the
head restraint and attached to the tether anchor on the
rear of the seatback. Then tighten all three straps as you
push the child restraint rearward and downward into the
seat.
Not all child restraint systems will be installed as we
have described here. Again, carefully follow the instruc-
tions that come with the child restraint system.
NOTE:
If your child restraint seat is not LATCH com-
patible, install the restraint using the vehicle seat belts.
WARNING!
An incorrectly anchored tether strap could lead to
increased head motion and possible injury to the
child. Use only the anchor position directly behind
the child seat to secure a child restraint top tether
strap.

LATCH — Child Seat Anchorage System (Lower
Anchors and Tether for CHildren)
Your vehicle’s rear seat is equipped with the child
restraint anchorage system called LATCH. The LATCH
system provides for the installation of the child restraint
without using the vehicle’s seat belts, instead securing
the child restraint using lower anchorages and upper
tether straps from the child restraint to the vehicle
structure.
LATCH-compatible child restraint systems are now avail-
able. However, because the lower anchorages are to be
introduced over a period of years, child restraint systems
having attachments for those anchorages will continue to
also have features for installation using the vehicle’s seat
belts. Child restraints having tether straps and hooks for
connection to the top tether anchorages have been avail-
able for some time. For some older child restraints, many
child restraint manufacturers offer add-on tether strapkits or retro-fit kits. You are urged to take advantage of all
the available attachments provided with your child re-
straint in any vehicle.
NOTE:
When using the LATCH attaching system to
install a child restraint, please ensure that all seat belts
not being used for occupant restraints are stowed and out
of reach of children. It is recommended that before
installing the child restraint, buckle the seat belt so the
seat belt is tucked behind the child restraint and out of
reach. If the buckled seat belt interferes with the child
restraint installation, instead of tucking the seat belt
behind the child restraint, route the seat belt through the
child restraint belt path and then buckle it. This should
stow the seat belt out of the reach of an inquisitive child.
Remind all children in the vehicle that the seat belts are
not toys and should not be played with, and never leave
an unattended child in the vehicle.
68 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The rear seating positions have lower anchorages that are
capable of accommodating LATCH-compatible child
seats having flexible, webbing-mounted lower attach-
ments. Child seats with fixed lower attachments must be
installed in the outboard positions only. Regardless of the
specific type of lower attachment,NEVERinstall
LATCH-compatible child seats such that two seats share
a common lower anchorage.
If you are installing LATCH-compatible child restraints
in adjacent rear seating positions, you can use the
LATCH anchors or the vehicle’s seat belt for the outboard
position, but you must use the vehicle’s seat belt at the
center position. If your child restraints are not LATCH-
compatible, you can only install the child restraints using
the vehicle’s seat belts. Please refer to the next section for
typical installation instructions.Installing the LATCH-Compatible Child Restraint
System
We urge you to carefully follow the directions of the
manufacturer when installing your child restraint. Not all
child restraint systems will be installed as described here.
Again, carefully follow the installation instructions that
were provided with the child restraint system.
The rear seat lower anchorages are round bars,
located at the rear of the seat cushion where it
meets the seatback, and are visible when you
lean into the rear seat to install the child
restraint. You will easily feel them if you run your finger
along the intersection of the seatback and seat cushion
surfaces.
