Side air bags (if equipped)
Side air bags (side impact and/or curtain
air bags) are designed to inflate when
an impact is detected by side collision
sensors depending on the crash severity,
speed or angles of impact resulting from
a side impact collision.
Although the front air bags (driver’s and
front passenger’s air bags) are designed
to inflate only in frontal collisions,
they also may inflate in other types of
collisions if the front impact sensor
detect a sufficient impact. Side air bags
(side impact and/or curtain air bags) are
designed to inflate only in side impact
collisions, but they may inflate in other
collisions if the side impact sensors
detect a sufficient impact.
If the vehicle chassis is impacted by
bumps or objects on unimproved roads
or sidewalks, air bags may deploy.
Drive carefully on unimproved roads
or on surfaces not designed for vehicle
traffic to prevent unintended air bag
deployment.
Air bag non-inflation conditions
OBC3030029OBC3030029
• In certain low-speed collisions the air
bags may not deploy. The air bags are
designed not to deploy in such cases
because they may not provide benefits
beyond the protection of the seat
belts in such collisions.
OBC3030030OBC3030030
• Front air bags are not designed to
inflate in rear collisions, because
occupants are moved backward by
the force of the impact. In this case,
inflated air bags would not be able to
provide any additional benefit.

OBC3030028OBC3030028
• Front air bags may not inflate in side
impact collisions, because occupants
move to the direction of the collision,
and thus in side impacts, frontal air
bag deployment would not provide
additional occupant protection.
OGB034038OGB034038
• In a slant or angled collision, the force
of impact may direct the occupants in
a direction where the air bags would
not be able to provide any additional
benefit, and thus the sensors may not
deploy any air bags.
OBC3030032OBC3030032
• Just before impact, drivers often brake
heavily. Such heavy braking lowers the
front portion of the vehicle causing
it to “ride” under a vehicle with a
higher ground clearance. Air bags
may not inflate in this “under-ride”
situation because deceleration forces
that are detected by sensor may be
significantly reduced by such “under-
ride” collisions.
OHI038166OHI038166
• Air bags do not inflate in rollover
accidents because vehicle can not
detect rollover accident.
However, side and/or curtain air bags
may inflate when the vehicle is rolled
over after side impact collision.

WARNING
• Reverse Parking Distance Warning
is a supplemental system. The
operation of the system can be
affected by several factors (including
environmental conditions). It is the
responsibility of the driver to always
check the rear view before and while
parking.
• Your new vehicle warranty does not
cover any accidents or damage to
the vehicle due to the malfunction of
Reverse Parking Distance Warning.
• Pay close attention when driving near
objects, pedestrians, and especially
children. Some objects may not be
detected by the ultrasonic sensors,
due to the objects distance, size or
material, all of which can limit the
effectiveness of the sensor.
Limitations of the system
