While the vehicle is being driven, all ve-
hicle occupants should have the seatback
upright, sit well back in the seat and prop-
erly wear the seat belts provided.
CAUTION
Do not drive the vehicle unless the
occupants are properly seated. Do
not allow any passengers to sit on
top of a folded−down seatback, or
in the luggage compartment or car-
go area. Persons not properly
seated and/or not properly re-
strained by seat belts can be killed
or severely injured in the event of
emergency braking or a collision.
During driving, do not allow any
passengers to stand up or move
around between seats. Otherwise,
death or severe injuries can occur
in the event of emergency braking
or a collision.
Driver seat
CAUTION
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 5075 mm (23 in.) of
inflation, placing yourself 250 mm (10
in.) 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 250
mm (10 in.) away now, you can
change your driving position in sever-
al 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. Although vehicle designs vary,
many drivers can achieve the 250
mm (10 in.) distance, even with the
driver seat all the way forward, sim-
ply 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 air-
bag toward your chest instead of
your head and neck.
The seat should be adjusted as rec-
ommended by NHTSA above, while
still maintaining control of the foot
pedals, steering wheel, and your view
of the instrument panel controls.

To make only slight changes to an already
memorized position, the easiest way is to
first activate the memorized position, then
make the desired changes and perform
step 2 above.
CY13301
RECALLING THE MEMORIZED POSITION
When you push button 1" or 2", a
beep will sound and the driving posi-
tion will be automatically adjusted to
the position recorded for that button.
The memorized position can be recalled
under the following conditions:
The engine switch is in the ON" posi-
tion and the selector lever is in the P"
position.
The engine switch is turned to the
LOCK" position or the key is not in
the engine switch, and less than 30
seconds have passed since opening
the driver ’s door.To stop the operation, push any driving
position memory button.
To reactivate the system, push the button
1" or 2" again.
If the vehicle’s battery is disconnected,
the memory will be erased and the posi-
tions will have to be set again.
CAUTION
Do not start the vehicle while the
adjustments are being made.
Take care not to select the wrong
button, or the seat could strike the
rear passenger or hit your body
against the steering wheel. If this
happens, you can stop the move-
ment by pressing another driving
position memory switch.

The seat belt pretensioner system con-
sists mainly of the following components
and their locations are shown in the il-
lustration.1. Front airbag sensors
2. SRS warning light
3. Front passenger occupant classification indicator light
4. Front passenger occupant classification system (ECU and sensors)
5. Seat belt pretensioner assemblies
6. Front passenger ’s seat belt buckle switch
7. Airbag sensor assembly The seat belt pretensioners are controlled
by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor.
When the seat belt pretensioners are acti-
vated, an operating noise may be heard
and a small amount of non−toxic gas may
be released. This does not indicate that
a fire is occurring. This gas is normally
harmless.
Once the seat belt pretensioners have
been activated, the seat belt retractors
remain locked.CAUTION
Do not modify, remove, strike or
open the seat belt pretensioner as-
semblies, airbag sensor or sur-
rounding area or wiring. Failure to
follow these instructions may pre-
vent the seat belt pretensioners
from activating correctly, cause sud-
den operation of the system or dis-
able the system, which could result
in death or serious injury. Consult
your Toyota dealer about any repair
and modification.
Do not modify or change the sus-
pension system. Such changes may
cause the curtain shield airbags to
inflate accidentally, which could re-
sult in death or serious injury. Con-
sult your Toyota dealer about any
repair and modification.
Do not use tires or wheels other
than the manufacture’s recom-
mended size. Such a use may cause
the curtain shield airbags and seat
belt pretensioners to inflate acci-
dentally, which could result in death
or serious injury. For details, see
Checking and replacing tires" on
page 443 in Section 7−2.
Do not place luggage heavier than
specified on the roof luggage carri-
er. Such luggage may cause the
curtain shield airbags and seat belt
pretensioners to inflate accidentally,
which could result in death or seri-
ous injury. For details, see Roof
luggage carrier" on page 334 in
Section 1−10.

CY13280
The SRS front airbag system consists
mainly of the following components, and
their locations are shown in the illustra-
tion.1. Front airbag sensors
2. SRS warning light
3. Front passenger occupant classification indicator light
4. Airbag module for front passenger (airbag and inflator)
5. Front passenger occupant classification system (ECU and sensors)
6. Front passenger ’s seat belt buckle switch
7. Driver ’s seat belt buckle switch 8. Driver ’s seat position sensor
9. Airbag sensor assembly
10. Airbag module for driver (airbag and inflator)
The airbag sensor assembly consists of a
safing sensor and airbag sensor.
The front airbag sensors constantly moni-
tor the forward deceleration of the vehicle.
If an impact results in a forward decelera-
tion beyond the designed threshold level,
the system triggers the airbag inflators. At
this time a chemical reaction in the infla-
tors very quickly fills the air bags with
non−toxic gas to help restrain the forward
motion of the occupants. The front airbags
then quickly deflate, so that there is no
obstruction of the driver ’s vision should it
be necessary to continue driving.
When the airbags inflate, they produce a
loud noise and release some smoke and
residue along with non−toxic gas. This
does not indicate a fire. This smoke may
remain inside the vehicle for some time,
and may cause some minor irritation to
the eyes, skin or breathing. Be sure to
wash off any residue as soon as possible
to prevent any potential skin irritation with
soap and water. If you can safely exit
from the vehicle, you should do so imme-
diately. Deployment of the airbags happens in a
fraction of a second, so the airbags must
inflate with considerable force. While the
system is desi
gned to reduce serious inju-
ries, primarily to the head and chest, it
may also cause other, less severe injuries
to the face, chest, arms and hands. These
are usually in the nature of minor burns
or abrasions and swelling, but the force of
a deploying airbag can cause more seri-
ous injuries, especially if an occupant’s
hands, arms, chest or head is in close
proximity to the airbag module at the time
of deployment. This is why it is important
for the occupant to: avoid placing any
object or part of the body between the
occupant and the airbag module; sit
straight and well back into the seat; wear
the available seat belt properly; and sit as
far as possible from the airbag module,
while still maintaining control of the ve-
hicle.
Parts of the airbag module (steering wheel
hub, airbag cover and inflator) may be hot
for several minutes after deployment, so
do not touch! The airbags inflate only
once. The windshield may be damaged by
absorbing some of the force of the inflat-
ing airbag.
