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.
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.
Safety belt locking modes
All safety restraints in the vehicle are combination lap and shoulder
belts. The driver safety belt and the optional front and rear center seat
safety belt have the first locking mode described below only. All outboard
passenger and outboard rear safety belts have both types of locking
modes described as follows:
Vehicle sensitive mode
This is the normal retractor mode, which allows 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.
In addition, the retractor is designed to lock if the webbing is pulled out
too quickly. If this occurs, let the belt retract slightly and pull webbing
out again in a slow and controlled manner.
