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, 
front passenger airbag, side impact air-
bags, head protection window curtain 
airbags for side windows), ETD (seat belt 
emergency tensioning device), and front 
seat knee bolsters. The system is de-
signed to enhance the protection of-
fered to properly belted occupants in 
certain frontal (front airbags) and side 
(side impact and window curtain air-
bags) impacts which exceed preset de-
ployment thresholds and in certain 
rollovers (window curtain airbags).
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-
m e n .  I f  t h e  b e l t  i s  p o s i t i o n e d  a c r o s s  y o u r  
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.
