Front seat belt pretensioners
16E228
The driver and front passenger's seat belt
pretensioners are designed to be activated in
response to a severe frontal impact.
When the airbag sensor detects the shock of a severe
frontal impact, the front seat belts are quickly drawn
back in by the retractors so that the belts snugly restrain
the front seat occupants.
The front seat belt pretensioners are activated even with
no passenger in the front seat.
Collisions occurring at certain speeds and angles may
cause the seat belt pretensioners and SRS airbags not
to operate all together.

STARTING AND DRIVING
312
Anti±lock brake system is not designed to shorten the
stopping distance: Always drive at the moderate speed
and maintain a safe distance from the vehicle in front of
you. Compared with vehicles without an anti±lock
brake system, your vehicle may require a longer
stopping distance in the following cases:
 Driving on rough, gravel or snow±covered roads.
 Driving with tire chains installed.
 Driving over the steps such as the joints on the road.
 Driving on roads where the road surface is pitted or
has other differences in surface height.
Install all 4 tires of specified size at appropriate
pressure: The anti±lock brake system detects vehicle
speeds using the speed sensors for respective wheels'
turning speeds. The use of tires other than specified
may fail to detect the accurate turning speed resulting
in a longer stopping distance.
