G
USE SEAT BELTS PROPERLY

Seat belts can only work when used
properly. Never wear seat belts in any
other way than as described in this sec-
tion, as that could result in serious inju-
ries in case of an accident.


Each occupant should wear their seat
belt at all times, because seat belts help
reduce the likelihood of and potential
severity of injuries in accidents, includ-
ing rollovers. The integrated restraint
system includes SRS (driver airbag, pas-
senger front airbag, side impact airbags,
head protection window curtain airbags
for side windows), ETD (seat belt emer-
gency tensioning device), and front seat
knee bolsters. The system is designed
to enhance the protection offered to
properly belted occupants in certain
frontal (front airbags) and side (side im-
pact airbags and window curtain air-
bags) impacts which exceed preset
deployment thresholds.


Never wear the shoulder belt under your
arm, against your neck or off your shoul-
der. In a crash, your body would move
too far forward. That would increase the
chance of head and neck injuries. The
belt would also apply too much force to
the ribs or abdomen, which could se-
verely injure internal organs such as
your liver or spleen.


Never wear belts over rigid or breakable
objects in or on your clothing, such as
eyeglasses, pens, keys, etc., as these
might cause injuries.


Position the lap belt as low as possible
on your hips and not across the abdo-
men. If the belt is positioned across your
abdomen, it could cause serious injuries
in a crash.


Never use a seat belt for more than one
person at a time. Do not fasten a seat
belt around a person and another per-
son or other objects.


Belts should not be worn twisted. In a
crash, you wouldn’t have the full width
of the belt to manage impact forces. The
twisted belt against your body could
cause injuries.


Pregnant women should also use a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible pres-
sure on the abdomen.


Never place your feet on the instrument
panel or on the seat. Always keep both
feet on the floor in front of the seat.

Warning!
G

other dangers, such as your view being
blocked, exhaust fumes may enter the
vehicle interior.
iThe doors unlock automatically after an
accident if the force of the impact
exceeds a preset threshold.
The vehicle automatically locks when
the ignition is switched on and the
wheels are turning at vehicle speeds of
approximately 9 mph (15 km/h) or
