■Alarm operation
The alarm is triggered in the following situations
●A locked door or trunk is opened in any way other than using a wireless remote
control, such as someone exiting the vehicle after the alarm is activated.
●The hood is opened while the vehicle is locked.
●The battery is reconnected.
■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.

1-7. Safety information
Airbag system componentsThe 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. Knee airbags

Before driving
■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 front windshield may crack.
■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.
■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.

CAUTION
■SRS airbag precautions
Observe the following precautions regarding the airbags. Failure to do so may
cause death or serious injury.
●The driver and all passengers in the vehicle must wear their seat belts properly.
The SRS airbags are supplemental devices to be used with the seat belts.
●The SRS driver airbag deploys with considerable force, and can cause death or
serious injury especially if the driver is very close to the airbag. The National
Highway Traffic Safety Admini stration ("NHTSA") advises:
Since the risk zone for driver airbag is th e first 2 - 3 in. (50 - 75 mm) of inflation,
placing yourself 10 in. (250 mm) from your driver airbag provides you with a
clear margin of safety. This distance is measured from the center of the steering
wheel to your breastbone. If you sit less than 10 in. (250 mm) away now, you can
change your driving position in several ways:
• Move your seat to the rear as far as you can while still reaching the pedals
comfortably.
• Slightly recline the back of the seat. Al though vehicle designs vary, many driv-
ers can achieve the 10 in. (250 mm) distance, even with the driver seat all the
way forward, simply by reclining the back of the seat somewhat. If reclining
the back of your seat makes it hard to see the road, raise yourself by using a
firm, non-slippery cushion, or raise the seat if your vehicle has that feature.
• If your steering wheel is adjustable, ti lt it downward. This points the airbag
toward your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA above, while still main-
taining control of the foot pedals, steering wheel, and your view of the instrument
panel controls.

Installing child restraints using a seat belt (child restraint lock function belt)
■Rear facing child seat Infant/convertible
Place the child seat on the rear
seat facing the rear of the vehicle.
Run the seat belt through the infant
seat and insert the plate into the
buckle. Make sure that the belt is

Before driving
While pushing the child seat down
into the rear seat, allow the shoul-
der belt to retract until the child
seat is securely in place.
After the shoulder belt has
retracted to a point where there is
no slack in the belt, pull the belt to
check that it cannot be extended.
■Forward facing Convertible child seat
Place the child seat on the seat
facing the front of the vehicle.
Run the seat belt through the child
seat and insert the plate into the
buckle. Make sure that the belt is
not twisted.
Fully extend the shoulder strap and
then allow it to retract slightly into
the ALR lock mode.
Lock mode allows the seat belt to
retract only.

2-1. Driving procedures
CAUTION
■When shifting the shift lever
With automatic transmission vehicles, be careful not to shift the shift lever with the
accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may cause an
accident and result in death or serious injury.
■When the vehicle is stopped
●Do not race the engine.
If the vehicle is in any gear other than P (vehicles with an automatic transmission
only) or N the vehicle may accelerate suddenly and unexpectedly, and may cause
an accident.
●Do not leave the vehicle with the engine running for a long time.
If such a situation cannot be avoided, park the vehicle in an open space and
check that exhaust fumes do no t enter the vehicle interior.
●With automatic transmission vehicles, always keep a foot on the brake pedal
while the engine is running to prevent an accident caused by the vehicle moving.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the vehi-
cle when it is in the sun.
Failure to do so may result in the following.
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic material of eye glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior of
the vehicle, and may also cause a short circuit in the vehicle's electrical com-
ponents.
●Always apply the parking brake, shift the shift lever to P (vehicles with an auto-
matic transmission only), stop the engine and lock the vehicle.
Do not leave the vehicle unattend ed while the engine is running.
●Do not touch the exhaust pipe while the engine is running or immediately after
turning the engine off.
Doing so may cause burns.
●Do not leave the engine running in an area with snow build up, or where snow is
expected to fall.
Exhaust gases may enter the vehicle and cause gas poisoning.
