CAUTION: (Continued)
Roof-mounted rollover airbags are
designed to inflate in moderate to severe
crashes where something hits the side of
your vehicle, during a vehicle rollover,
or in a severe frontal impact. They are not
designed to inflate in rear crashes. If your
vehicle has roof-mounted airbags, they are
designed to provide both side impact
protection and rollover protection.
Everyone in your vehicle should wear a
safety belt properly — whether or not there
is an airbag for that person.
CAUTION:
{
Both frontal and roof-mounted rollover
airbags inflate with great force, faster than
the blink of an eye. If you are too close to
an inflating airbag, as you would be if you
were leaning forward, it could seriously
injure you. Safety belts help keep you in
position for airbag inflation before and
during a crash. Always wear your safety
belt even with frontal airbags. The driver
should sit as far back as possible while
still maintaining control of the vehicle.
Occupants should not lean on or sleep
against the door in the first or second row
seats, or the rear windows in the third row
seat, if your vehicle has roof-mounted
rollover airbags.
