3. Insert the belt tongue into the proper buckle for your seating position
until you hear a snap and feel it latch.
4. Make sure the tongue is securely fastened to the buckle by pulling on
the tongue.
WARNING: The lap belt should fit snugly and as low as possible
around the hips, not across the waist.
WARNING: Front and rear seat occupants, including pregnant
women, should wear safety belts for optimum protection in an
accident.
WARNING: Each seating position in your vehicle has a specific
safety belt assembly which is made up of one buckle and one
tongue that are designed to be used as a pair. 1) Use the shoulder belt
on the outside shoulder only. Never wear the shoulder belt under the
arm. 2) Never swing the safety belt around your neck over the inside
shoulder. 3) Never use a single belt for more than one person.
While you are fastened in the safety belt, the combination lap/shoulder
belt with a cinch tongue adjusts to your movement. However, if you
brake hard, turn hard, or if your vehicle receives an impact of 5 mph
(8 km/h) or more, the safety belt will become locked and help reduce
your forward movement.
Restraint of pregnant women
WARNING: Always ride and drive with your seatback upright
and the safety belt properly fastened. The lap portion of the
safety belt should fit snug and be positioned low across the hips. The
shoulder portion of the safety belt should be positioned across the
chest. Pregnant women should also follow this practice. See figure
below. Seating and Safety Restraints

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 used any time a 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 to Safety
restraints for children or Safety seats for children later in this chapter.Seating and Safety Restraints
