SRS airbag precautions
Observe the following precautions regarding the SRS 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 device s to be used with the seat belts.●
The SRS driver airbag deploys with consider able force, and can cause death or seri-
ous injury especially if the driver is very close to the airbag. The National Highway
Traffic Safety Administration (NHTSA) advises:
Since the risk zone for the driver’s 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 pedals com-
fortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 10 in. (250 mm) dis-
tance, even with the driver seat all the wa y 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 ad justable, tilt it downward. Th is points the airbag toward
your chest instead of your head and neck.
The seat should be adjusted as recommen ded by NHTSA above, while still maintain-
ing control of the foot pedals, steering whee l, and your view of the instrument panel
controls.

SRS airbag precautions
●
Do not hang coat hangers or other hard objects on the coat hooks. All of these items
could become projectiles and may cause deat h or serious injury, should the SRS cur-
tain shield ai rbags deploy.●
If a vinyl cover is put on the area where the SRS knee airbag will deploy, be sure to
remove it. ●
Do not use seat accessories which cover the parts where the SRS side airbags and
SRS seat cushion airbag inflate as they may interfere with inflation of the SRS airbags.
Such accessories may prevent the side ai rbags and SRS seat cushion airbag from
activating correctly, disable the system or cause the side airbag s and SRS seat cush-
ion airbag to inflate accidentally, re sulting in death or serious injury.●
Do not strike or apply significant levels of force to the areas around the SRS airbag
components or the front doors.
Doing so can cause the SRS airbags to malfunction. ●
Do not touch any of the component parts immediately after the SRS airbags have
deployed (inflated) as they may be hot. ●
Do not attach anything to or lean anything
against areas such as the dashboard, steering
wheel pad and lower portion of the instru-
ment panel.
These items can become projectiles when the
SRS driver, front passenger and knee airbags
deploy. ●
Do not attach anything to areas such as a
door, windshield, side windows, front or rear
pillar, roof side rail and assist grip.

SRS airbag precautions ●
If breathing becomes difficult after the SRS airbags have deployed, open a door or
window to allow fresh air in, or leave the vehicl e if it is safe to do so. Wash off any resi-
due as soon as possible to prevent skin irritation. ●
If the areas where the SRS airbags are stored, such as the steering wheel pad and
front and rear pillar garnishes, are damaged or cracked, have them replaced by your
Lexus dealer. ●
Do not place anything, such as a cushion, on the front passenger’s seat. Doing so will
disperse the passenger’s weight, which prevents the sensor from detecting the pas-
senger’s weight properly. As a result, th e SRS front airbags for the front passenger
may not deploy in the event of a collision. ■
Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications without
consulting your Lexus dealer. The SRS airb ags may malfunction or deploy (inflate)
accidentally, causing de ath or serious injury.●
