Single Stage vs. Dual Stage Air Bags
Depending on Ihe weight of your vehiclG you wifi
have either "'Single Stage Air Bags" or “Dual Stage Air
Bags", Vehicles that have a passenger sensing
system also have dual stage air hags. If the rearview
mirror in your vehicle has a passenger air bag
slalus indtcaier printed orr it, your vehide has the
passenger sensing system and therefore, it has dual
stage air bags. II Ihe rearview mirror In your vehicle does
not have a passeriger air bag status irhdicator printed
on it, then your vBhicle does not have the passenger
sensing System and il has single stage air bags.

If Uie front of your vehicle goes straighi into a wall that
doesn't move or defomn, Ihe threshold level for the
reduced deployment is about id to Ifi mph
[16 to 25 hm/h), and the threshold level tor a full
deployment Is aboul 20 lo 25 mph (32 to 4Û knVli), The
threshold level can vary, however, with spectlic
vehicle design, so thal it can be somewhat above or
below this range.
If your vehicle strikes somettiing thal will move or
deform, such as a parked car, the threshold le vet will be
higher, The air bag Is rot desigrted lo inflate In
roilDVErs, rear Impads, or in many side impacts because
inflation would not help the occupant.
Seat Position Sensors
Vehicle's with dual stage air bags are also equipped
with special sensors which enable The sensing system lo
monitor the position of both the driver and passenger
fronl seals. Tha seat posUion sensor provides
information which is used to deiermine it the air bags
