SAFETY RESTRAINTS
Safety restraints precautions
WARNING:Always drive and ride with your seatback upright
and the lap belt snug and low across the hips.
WARNING:To reduce the risk of injury, make sure children sit
in a rear seating position where they can be properly restrained.
WARNING:Never let a passenger hold a child on his or her lap
while the vehicle is moving. The passenger cannot protect the
child from injury in a collision.
WARNING:All occupants of the vehicle, including the driver,
should always properly wear their safety belts, even when an
airbag supplemental restraint system (SRS) is provided.
WARNING:It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, people riding in
these areas are more likely to be seriously injured or killed. Do not
allow people to ride in any area of your vehicle that is not equipped
with seats and safety belts. Be sure everyone in your vehicle is in a
seat and using a safety belt properly.
WARNING:In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a safety
belt.

Pregnant women should always
wear their safety belt. The lap belt
portion of a combination lap and
shoulder belt should be positioned
low across the hips below the belly
and worn as tight as comfort will
allow. The shoulder belt should be
positioned to cross the middle of
the shoulder and the center of the
chest.
Vehicle sensitive mode
Combination lap and shoulder belts in normal retractor mode allow free
shoulder belt length adjustment to your movements and locking in
response to vehicle movement. For example, if the driver brakes
suddenly or turns a corner sharply, or the vehicle receives an impact of
approximately 5 mph (8 km/h) or more, the combination safety belts will
lock to help reduce forward movement of the driver and passengers.
Belt sensitive mode
Combination lap and shoulder belts can also be made to lock manually by
quickly pulling on the shoulder belt.
Automatic locking mode
When to use the automatic locking mode
In this mode, the shoulder belt is automatically pre-locked. The belt will
still retract to remove any slack in the shoulder belt. The automatic
locking mode is not available on the driver safety belt.
This mode should be usedany timea child safety seat (except a
booster) is installed in a passenger front or outboard rear seating
position (if equipped). Children 12 years old and under should be
properly restrained in the rear seat whenever possible. Refer toSafety
restraints for childrenorSafety seats for childrenlater in this chapter.
