Failure to wear and properly fasten and position 
your seat belt greatly increases your risk of 
injuries and their likely severity in an accident. 
You and your passenger should always wear seat 
belts.If you are ever in an accident, your injuries can be 
considerably more severe without your seat belt 
properly buckled. Without your seat belt buckled, 
you are much more likely to hit the interior of the 
vehicle or be ejected from it. You can be seriously 
injured or killed.In th e sam e c rash, th e possibility  of injury or death  
is lessened if you are wearing your seat belt.Never let more people ride in the vehicle than there 
are seat belts available. Be sure everyone riding in 
the vehicle is correctly restrained with a separate 
seat belt.

• Never wear the shoulder belt under your arm, 
against you neck or off your shoulder. 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 severely injure internal organs such as 
your liver or spleen.• Each seat belt must never be used for more 
than one person at a time. Do not fasten a seat 
belt around a person and another person 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 pressure 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.

ONLY work with a special child seat designed to 
operate with it. It will not work with child seats 
which are not BabySmart

child seat (e.g. pillow), since it reduces the 
effectiveness of the deactivation system.Follow the manufacturer’s instructions for 
installation of special child seats.The passenger front airbag will not deploy only if 
the 7 indicator lamp remains illuminated.
Please be sure to check the indicator every time 
you use the special system child seat.
