This vehicle is equipped with an
event data recorder (EDR). The main purpose of an EDR is to
record, in certain crash or near
crash-like situations, such as an
air bag deployment or hitting a
road obstacle, data that will
assist in understanding how a
vehicle’s systems performed.
The EDR is designed to record
data related to vehicle dynamics
and safety systems for a short
period of time, typically 30 sec-
onds or less.
The EDR in this vehicle is
designed to record such data
as:
• How various systems in your
vehicle were operating;
• Whether or not the driver and passenger safety belts were
buckled/fastened;
• How far (if at all) the driver was depressing the accelera-
tor and/or brake pedal; and,
• How fast the vehicle was trav- eling.
These data can help provide a
better understanding of the cir-
cumstances in which crashes
and injuries occur.
NOTE: EDR data are recorded
by your vehicle only if a non-triv-
ial crash situation occurs; no
data are recorded by the EDR
under normal driving conditions
and no personal data (e.g.,
name, gender, age, and crash
location) are recorded. How-
ever, other parties, such as law
enforcement, could combine the

ion airbag will activate.
●The SRS front airbags for the front
passenger will not activate if there
is no passenger sitting in the front
passenger seat. However, the
SRS front airbags for the front
passenger may de ploy if luggage
is put in the seat, even if the seat
is unoccupied.
●The SRS seat cushion airbag on
the front passen ger seat will not
operate if the occupant is not
wearing a seat belt.
■SRS airbag deployment condi-
tions (SRS side and curtain
shield airbags)
●The SRS side and curtain shield
airbags will deploy i n the event of
an impact that exceeds the set
threshold level (the level of force
corresponding to the impact force
produced by an approximately
3300 lb. [1500 kg] vehicle colliding
with the vehicle cabin from a
direction perpendicular to the
vehicle orientation at an approxi-
mate speed of 12 - 18 mph [20 -
30 km/h]).
●Both SRS curtain shield airbags
may deploy in the event of a
severe side collision.
●Both SRS curtain shield airbags
will deploy in the event of vehicle
rollover.
●Both SRS curtain shield airbags
may also deploy in the event of a
severe frontal collision.
■Conditions under which the
SRS airbags may deploy
(inflate), other t han a collision
The SRS front airbags and SRS cur-
tain shield airbags may also deploy
if a serious impact occurs to the
underside of your vehicle. Some
examples are shown in the illustra-
tion.
●Hitting a curb, edge of pavement
or hard surface
●Falling into or jumping over a deep hole
●Landing hard or falling
The SRS curtain shield airbags may
also deploy under the situations
shown in the illustration.
●The angle of vehicle tip-up is mar-
ginal.
●The vehicle skids and hits a curb
stone.
■Types of collisions that may not
deploy the SRS airbags (SRS
front airbags)
The SRS front airbags do not gener-
ally inflate if the vehicle is involved
in a side or r ear collision, if it rolls
over, or if it is involved in a
low-speed frontal collision. But,
whenever a collis ion of any type
causes sufficient forward decelera-
tion of the vehicle, deployment of
the SRS front airbags may occur.
●Collision from the side
●Collision from the rear
●Vehicle rollover
