64 Safety and SecurityOccupant safety
Emergency tensioning device (ETD)
The seat belts are equipped with emergen-
cy tensioning devices and belt force limit-
ers.
The ETD is designed to activate in the fol-
lowing cases when the seat belts are fas-
tened:
in frontal or rear-end impacts exceed-
ing a preset severity level
if the restraint systems are operational 
and functioning correctly, see 
1indicator lamp (
page 56).
In an impact, emergency tensioning devic-
es remove slack from the belts in such a 
way that the seat belts fit more snugly 
against the body. Belt force limiters reduce 
the force exerted by the seat belts on oc-
cupants during a crash.
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.
