Noise from under vehicle after turning off the engine
Approximately five hours after the engine is turned off, you may hear sound coming
from under the vehicle for several minutes. This is the sound of a fuel evaporation
leakage check and, it does not indicate a malfunction.

●Use the head restraints designed for each respective seat.
●Adjust the head restraints to the correct position at all times.
●Do not drive with the head restraints removed.
■Rear head restraints
●Do not sit in the rear seats with the head restraints in the folded position.
●Do not fold the head restraints when passengers are seated in the rear seats.
●Do not allow passengers to sit on the folded head restraints.
NOTICE
■Rear head restraints
Do not press down excessively on the folded head restraints as doing so may cause
damage.

1-7. Safety information
10_IS250C/350C_UIn certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chem
ical reaction in the inflators quickly
fills the airbags with non-toxic gas to help restrain the motion of the occu-
pants.
■SRS warning light
This warning light system monitors the airbag sensor assembly, front airbag sensors,
side airbag sensor assemblies, driver's seat position sensor, driver's seat belt buckle
switch, seat belt pretensioner assemblies, inflators, interconnecting wiring and
power sources. ( →P. 4 6 4 )
■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, airbag cover and inflator) as well as
the front seats may be hot for several minutes. The airbag itself may also be hot.
●The windshield may crack.
■SRS airbag deployment conditions (front airbags)
●The front SRS airbags will deploy in the event of an impact that exceeds the
set threshold level (the level of force corresponding to a 12 - 18 mph [20 - 30
km/h] frontal collision with a fixed wall 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 threshold level, the SRS front airbags and the
seat belt pretensioners may not activate together.
●The SRS front passenger airbag will not activate if there is no passenger sitting
in the front passenger seat. However, the 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. 111)

■SRS airbag deployment conditions (side airbags)
●The SRS side airbags will deploy in the event of an impact that exceeds the set
threshold level (the level of force corresponding to the impact force produced
by a 3300 lb. [1500 kg] vehicle colliding with the vehicle cabin from a direc-
tion perpendicular to the vehicle orientation at a speed of 12 - 18 mph [20 - 30
km/h]).
●The SRS side airbag on the passenger seat will not activate if there is no passen-
ger sitting in the front passenger seat. However, the side airbag on the passen-
ger seat may deploy if luggage is put in the seat, even if the seat is unoccupied.
(→ P. 111)
■Conditions under which the SRS airbags may deploy (inflate), other than a colli-
sion
The SRS front airbags may also deploy if a serious impact occurs to the underside of
your vehicle. Some examples are shown in the illustration.
■Types of collisions that may not deploy the SRS airbag (front airbags)
The SRS front airbags are generally not designed to inflate if the vehicle is involved
in a side or rear collision, if it rolls over, or if it is involved in a low-speed frontal colli-
sion. But, whenever a collision of any type causes sufficient forward deceleration of
the vehicle, deployment of the SRS front airbags may occur.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or vehicle falling
●Collision from the side
●Collision from the rear
●Vehicle rollover

10_IS250C/350C_U
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 the 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 pedalscomfortably.
• Slightly recline the back of the seat. Although vehicle designs vary, many drivers 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, tilt 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.
