Here are the most important things to know about the
airbag system:
CAUTION:
{
You can be severely injured or killed in a crash
if you are not wearing your safety belt — even
if you have airbags. Wearing your safety belt
during a crash helps reduce your chance of
hitting things inside the vehicle or being
ejected from it. Airbags are "supplemental
restraints" to the safety belts. All airbags are
designed to work with safety belts but do not
replace them.

CAUTION: (Continued)
Frontal airbags for the driver and right front
passenger are designed to deploy only in
moderate to severe frontal and near frontal
crashes. They are not designed to inflate in
rollover, rear or low-speed frontal crashes,
or in many side crashes. And, for some
unrestrained occupants, frontal airbags may
provide less protection in frontal crashes than
more forceful airbags have provided in the
past. The roof-mounted side impact airbags
are designed to inflate only in moderate to
severe crashes where something hits the side
of your vehicle. They are not designed to
inflate in frontal, in rollover or in rear crashes.
Everyone in your vehicle should wear a safety
belt properly — whether or not there is an
airbag for that person.
