1-8. Safety information
Your vehicle is equipped with “ADVANCED AIRBAGS” designed based
on US motor vehicle safety standards (FMVSS208). The airbag system
controls airbag deployment power for the driver and front passenger. The
driver airbag system consists of the dr iver's seat position sensor etc. The
front passenger's airbag system consists of the front passenger occupant
classification sensor etc.
The main SRS airbag system componen ts are shown above. The SRS air-
bag system is controlled by the airb ag sensor assembly. The airbag sen-
sor assembly consists of a safing sensor and an airbag sensor.
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chemica l reaction in the inflators quickly
fills the airbags with non-toxic gas to he lp restrain the motion of the occu-
pants.
■If the SRS airbags deploy (inflate)
●Bruising and slight abrasion s may result from contact with a deploying (inflating)
SRS airbag.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel hub, airbag cover and inflator) as
well as the front seats, and parts of the front pillar and roof side rail, may be hot
for several minutes. The airbag itself may also be hot.
●The windshield may crack.

2-1. Driving procedures
CAUTION
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the hybrid system
running. This prevents the vehicle from creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelerator
pedals to avoid depressing the wrong pedal. 
Accidentally depressing the accelerator pedal instead of the brake pedal will
result in sudden acceleration that may lead to an accident that could result in
death or serious injury.
●The driver should pay attention to pedest rians when the vehicle is powered only
by the electric motor (traction motor). Because there is no engine sounds, the
pedestrians may misjudge the vehicle’s movement.
●Do not drive the vehicle over or stop the vehicle near flammable materials.
●Do not let the vehicle roll backwards while the shift lever is in a driving position, or
roll forward while the shift lever is in “R”. 
Doing so may cause the hybrid system not to operate or lead to poor brake and
steering performance, resulting in an accident or damage to the vehicle.
●If the smell of exhaust is noticed inside the vehicle, open the windows and check
that the trunk is closed. 
Large amounts of exhaust in the vehicle can cause driver drowsiness and eventu-
ally, death. Have the cause of the problem inspected immediately.
