GENERAL INFORMATION
M2370000100851
Electric power steering system has been adopted for
all models in order to ensure an optimised steering
feeling.
FEATURES
•Improved fuel consumption by reduction of
engine load, and weight saving by decrease of
the number of parts have been achieved with the
introduction of the electric power steering system.
•3-spoke type steering wheel integrated with an
SRS airbag has been adopted.
•Impact-absorbing mechanism and tilt steering
mechanism have been adopted.

GENERAL INFORMATION
M2521000100819
•The driver’s and front passenger’s air bags and
seat belts with pre-tensioner are standard
equipped on all vehicles.
•To improve safety against side impact collisions,
optional side-airbags and curtain air bags are
available to all the models.
•An inflator that does not contain sodium azide is
adopted for all types of the air bag modules.
SRS FRONT AIR BAG
The SRS is designed to supplement the front seat
belts. It reduces injury to the front passenger(s) by
deploying air bag(s) in case of a frontal collision.
SRS SIDE-AIRBAG
Side-airbag systems in the front seats are activated
when side collision applied to the vehicle exceed cri
-
teria to protect the occupants’ upper bodies.
SRS CURTAIN AIR BAG
The curtain air bag systems are activated when side
collision applied to the vehicle exceed criteria, to pro
-
tect the heads of the occupants in the front and rear
seats.
SEAT BELT WITH PRE-TENSIONER
The seat belts with pre-tensioner work simultane-
ously with the SRS. The pre-tensioner takes up seat
belt slack immediately when a collision takes place,
restraining the front passengers sooner than the
SRS. This prevents the passengers from moving for
-
ward.
