and the narrower track, if this vehicle is out of control it
may roll over when some other vehicles may not.
Do not attempt sharp turns or abrupt maneuvers or other
unsafe driving actions that can cause loss of vehicle
control. Failure to operate this vehicle safely may result
in an accident, roll over of the vehicle, and severe or fatal
injury. Drive carefully.Failure to use driver and passenger seat beltsprovided
is a major cause of severe or fatal injury. In fact, the U.S.
government notes that the universal use of existing seat
belts could cut the highway death toll by 10,000 or more
each year, and could reduce disabling injuries by 2
million annually. In a roll over crash an unbelted person
is significantly more likely to die than a person wearing
a seat belt. Always buckle up.

14 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

How to Disengage The Automatic Locking Mode
Disconnect the combination lap/shoulder belt and allow
it to retract completely to disengage the automatic lock-
ing mode and activate the vehicle sensitive (emergency)
locking mode.
Energy Management Feature
This vehicle has a safety belt system with an energy
management feature in the front seating positions to help
further reduce the risk of injury in the event of a head-on
collision.
This safety belt system has a retractor assembly that is
designed to release webbing in a controlled manner. This
feature is designed to help reduce the belt force acting on
the occupant's chest.
WARNING!
²After a vehicle collision, the front passenger out-
board seat belt system must be checked by a
qualified technician to verify that the ªautomatic
locking retractorº feature for child seats is still
functioning properly. In addition, all seat belts
should be checked for proper function.

if the seat belt assembly ªautomatic locking re-
tractorº feature or any other seat belt function is

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:
²Does not come on during the 6 to 8 seconds after the
ignition switch is first turned on.
²Remains on after the 6 to 8 second interval.
²Comes on for any period of time while driving.
Child Restraint
Everyone in your vehicle needs to be buckled up all the
time Ð 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.
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 can
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 Small Children
There are different sizes and types of restraints for
children from newborn size to the child almost large
