Rear side airbag modules (airbag and inflator)
The SRS side airbag and curtain shield airbag system consists
mainly of the above components, and their locations are
shown in the illustration.
The SRS side airbag and curtain shield airbag system is
controlled by the airbag sensor assembly. The airbag sensor
assembly consists of a safing sensor and airbag sensor. In a severe side impact, the side and curtain shield airbag
sensor and/or the curtain shield airbag sensor trigger(s) the
side airbag inflators and/or the curtain shield airbag inflators.
At this time a chemical reaction in the inflators quickly fills the
airbags with non
−toxic gas to help restrain the lateral motion
of the occupants.
When the airbags inflate, they produce a fairly loud noise and
release some smoke and residue along with non −toxic gas.
This does not indicate a fire. This smoke may remain inside
the vehicle for some time, and may cause some minor irritation
to the eyes, skin or breathing. Be sure to wash off any residue
as soon as possible to prevent any potential skin irritation with
soap and water. If you can safely exit from the vehicle, you
should do so immediately.
Deployment of the airbags happens in a fraction of a second,
so the airbags must inflate with considerable force. While the
system is designed to reduce serious injuries, it may also
cause minor burns or abrasions and swelling.
Front (and outboard rear) seats as well as the parts of the front
and rear pillars, and roof side rail may be hot for several
minutes, but the airbags themselves will be hot. The airbags
are designed to inflate only once.

Consumption
The consumption is calculated and displayed based on
the driving distance and the fuel consumption for 2
seconds with engine running.
The value is updated every 0.5 seconds.
If you are driving at low speeds just before stopping, the
accurate figure may not be shown.
After Refueling
The consumption after refueling is calculated and
displayed based on the total driving distance and the total
fuel consumption after refueling.
The value is updated every 10 seconds.
When refueling, be sure to stop your vehicle and turn the
engine switch off. Cruising Range
How far you can drive with the remaining fuel is
displayed.
Even though the display indicates sufficient miles to run, if the
fuel level on the fuel gauge approaches “E” or the low fuel level
warning light comes on, fill the fuel tank as soon as possible.
INFORMATION
 When you first start driving your new vehicle, the
correct cruising range may not be shown. One or
more refills of 10 gallons or more may be required for
the system to set its calibration.
 The cruising range displayed is calculated based on
past fuel consumption and may vary according to
your driving style and road condition.
