Alarm
Deactivating or stopping the alarmDo one of the following:
● Unlock the doors using the key or the wireless remote control.
● Start the engine.
■Items to check before locking the vehicle
To prevent unintended triggering of the alar m, check that there is no one in the vehi-
cle, and that all windows and the moon roof are closed before locking the vehicle.
■When the battery is disconnected
Be sure to cancel the alarm system.
If the battery is discharged before canceling the alarm, the system may be triggered
when the battery is reconnected.
The system sounds the alarm and flashes lights when forcible entry is
detected.
To arm the alarm, exit the vehi-
cle, make sure that the doors
and hood are closed, and lock
all the doors.
The system will operate auto-
matically once the indicator
begins to flashing.

1-7. Safety information
Correct driving posture
Drive with a good posture as follows:
Sit upright and well back in
the seat.
Adjust the position of the seat
forward or backward to
ensure the pedals can be
reached and easily
depressed to the extent
required. (P. 3 4 )
Adjust the seatback so that
the controls are easily opera-
ble.
Adjust the tilt and telescopic
positions of the steering
wheel downward so the air-
bag is facing your chest.
( P. 5 7 )
Lock the head restraint in
place with the center of the
head restraint closest to the
top of your ears. ( P. 4 7 )
Wear the seat belt correctly.
( P. 4 9 )

CAUTION
■Caution while driving
●Do not adjust the position of the driver’s seat.
Doing so could cause the driver to lose control of the vehicle.
●Do not place a cushion between the driver or passenger and the seatback.
A cushion may prevent correct posture from being achieved, and reduce the
effectiveness of the seat belt and head re straint, increasing the risk of death or
serious injury to the driver or passenger.
●Do not place anything under the front seats.
Objects placed under the front seats may become jammed in the seat tracks and
stop the seat from locking in place. This may lead to an accident. The adjustment
mechanism may also be damaged.
■Adjusting the seat position
●Do not recline the seat more than necessary when the vehicle is in motion, to
reduce the risk of slid ing under the lap belt.
If the seat is too reclined during an accident, the lap belt may slide past the hips
and apply restraint forces directly to th e abdomen or your neck may contact the
shoulder belt, increasing the ri sk of death or serious injury.
●Take care when adjusting the seat position to ensure that other passengers are
not injured by the moving seat.
●Do not put your hands under the seat or near the moving parts to avoid injury.
Fingers or hands may become jammed in the seat mechanism.

Before driving
SRS airbags
The SRS airbags inflate when the vehicle is subjected to certain types of
severe impacts that may cause significant injury to the occupants. They
work together with the seat belts to he lp reduce the risk of death or serious
injury.
Front airbags
Driver airbag/front passenger airbag
Can help protect the head and ches t of the driver and front passen-
ger from impact with interior components.
Side and curtain shield airbags
Side airbag
Can help protect the torso of the front occupants.
Curtain shield airbag
Can help protect primarily the head of front occupants and rear out-
board occupants.

1-7. Safety information
Airbag system componentsYour vehicle is equipped with “ADVANCED AIRBAGS” designed based
on US motor vehicle safety standa rds (FMVSS208). The airbag system
controls airbag deployment power for the driver and front passenger. The
driver airbag system consist s of the driver’s seat position sensor etc. The
front passenger’s airbag system con sists of the front passenger occupant
classification sensor etc. Front passenger airbag

Before driving
The main SRS airbag system components 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 abrasions 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.

1-7. Safety information
■Operating conditions (front airbags)
●The SRS front airbags will deploy if the severity of the frontal impact is above the
designed threshold level, comparable to an approximate 15 mph (25 km/h) col-
lision when the vehicle impacts straight into a fixed barrier that does not move
or deform.
However, this threshold velocity will be considerably higher if the vehicle strikes
an object, such as a parked vehicle or sign pole, which can move or deform on
impact, or if the vehicle is involved in an underride collision (e.g. a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a truck, etc.).
●It is possible that in some collisions where the forward deceleration of the vehi-
cle is very close to the designed thresh old level, the SRS front airbags and the
seat belt pretensioners ma y not activate together.
●The SRS front passenger airbag will not activate, if there is not passenger sitting
in the front passenger seat. However, th e front passenger airbag may deploy, if
luggage is put in the seat or the seat belt is fastened, even if the seat is unoccu-
pied. ( P. 9 0 )
■Operating conditions (side and curtain shield airbags)
●The SRS side airbags and curtain shield ai rbags are designed to inflate when the
passenger compartment is subjected to a severe impact from the side.
●The SRS side airbag on the passenger seat will not activate if there is no passen-
ger sitting in the front passenger seat. Ho wever, the side airbag on the passen-
ger seat may deploy, if luggage is put in the seat, even if the seat is unoccupied.
