Before driving
Seat belt comfort guide (outside rear seats)If the shoulder belt sits close to a
person’s neck, slide the seat belt
comfort guide forward.
Seat belt pretensioners (front and outside rear seats)The pretensioner helps the seat
belt to quickly restrain the occu-
pant by retracting the seat belt
when the vehicle is subjected to
certain types of severe frontal colli-
sion.
The pretensioner may not activate
in the event of a minor frontal
impact, a side impact or a rear
impact.
■ Adjusting the height of the belt (front seats)
Down
Up
Move the height adjuster up and
down as needed until you hear a
click.

1-3. Adjustable components
Pre-collision seat belts (front seats of vehicles with pre-collision system)When the pre-collision sensor detects an obstacle and determines that a
collision is unavoidable, the seat belt s lessen collision injury by retracting
the slack in the front seat belts befo re the collision, thus restraining the
driver and passenger at an earlier stage.
The seat belts will also operate in the event of sudden braking. ( P. 1 4 4 )
■Emergency locking retractor (ELR)
The retractor will lock the belt during a sudd en stop or on impact. It may also lock if
you lean forward too quickly. A slow, easy motion will allow the belt to extend so that
you can move around fully.
■Automatic locking retractor (ALR)
When a passenger's shoulder belt is completely extended and then retracted even
slightly, the belt is locked in that position and cannot be extended. This feature is
used to hold the CRS firmly. To free the belt again, fully retract the belt and then pull
the belt out once more. ( P. 7 1 )
■Pregnant women
Obtain medical advice and wear the seat belt
in the proper way. ( P. 3 0 )
Women who are pregnant should position
the lap belt as low as possible over the hips in
the same manner as other occupants. Extend
the shoulder belt completely over the shoul-
der and position the belt across the chest.
Avoid belt contact over the rounding of the
abdominal area.
If the seat belt is not worn properly, not only a
pregnant woman, but also the fetus could suf-
fer death or serious injury as a result of sud-
den braking or a collision.
