Before driving
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on US motor vehicle sa fety standards (FMVSS208). The airbag system
controls airbag deployment power for the driver and front passenger. The
driver airbag system consists of the driver seat’s position sensor etc. The
front passenger’s airbag system consist s of the front passenger occupant
classification sensor etc.
In certain types of severe frontal or side impacts, the SRS airbag s
ystem
triggers the airbag inflators. A chemica l reaction in the inflators quickly
fills the airbags with non-toxic gas to help 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 seats, and parts of the front and rear pillars, and roof side rail, may be
hot for several minutes. The airbag itself may also be hot.
●The windshield may crack.

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 Administration (“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) distan ce, 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.

Before driving
■There is a malfunction in the system
*1: The system judges a person of adult size as an adult. When a smaller
adult sits in the front passenger seat, the system may recognize him/
her as a child depending on his/her physique and posture.
*2: In the event the front passenger does not wear a seat belt.
*3: When a large child who has outgrown a child restraint system sits in
the fr
ont passenger seat, the sys tem may recognize him/her as an
adult depending on his/her physique or posture.
*4: Never install a real-facing child restraint system on the front passen -
ger seat. A forward-facing child r
estraint system should only be
installed on the front passenger seat when it is unavoidable. 
( P. 8 9 )
*5: In case the indicator is not illuminated, consult this manual as for installing the child r
estraint system properly. ( P. 8 1 )
