Installation of a mobile two way radio system
As the installation of a mobile two −way radio system in
your vehicle could affect electronic systems such as
multiport fuel injection system/sequential multiport fuel
injection system, electronic throttle control system, cruise
control system, dynamic laser cruise control system, anti −
lock brake system, traction control system, vehicle stability
control system, SRS airbag system and seat belt preten-
sioner system, be sure to check with your Toyota dealer
for precautionary measures or special instructions regard-
ing installation.
Tires and loading on your To y o t a
Underinflated or overinflated tire pressure and the
excess load may result in the deterioration of
steering ability and braking ability, leading to an
accident. Check the tire inflation pressure periodi-
cally and be sure to keep the load limits given in
this Owner ’s Manual. For details about tire inflation
pressure and load limits, see pages 398 and 471.

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 se-
verely injured in the event of emer-
gency braking or a collision.
During driving, do not allow any
passengers to stand up or move
around between seats. Otherwise,
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 50—75 mm (2—3 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.

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 im-
mediately. 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.CAUTION
The driver or front passenger who is
too close to the steering wheel or
dashboard during airbag deployment
can be killed or seriously injured.
Toyota strongly recommends that:
The driver sit as far back as pos-
sible from the steering wheel while
still maintaining control of the ve-
hicle.
The front passenger sit as far back
as possible from the dashboard.
All vehicle occupants be properly
restrained using the available seat
belts.
For instructions and precautions con-
cerning the seating position, see
“—Front seat precautions” on page
56 in this Section.

Do not sit on the edge of the seat
or lean against the dashboard when
the vehicle is in use, since the
front passenger airbag could inflate
with considerable speed and force.
Anyone who is up against, or very
close to, an airbag when it inflates,
can be killed or seriously injured.
Sit up straight and well back in the
seat, and always use your seat belt
properly.Toyota strongly recommends that all
infants and children be placed in
the rear seat of the vehicle and be
properly restrained.
Do not hold a child on your lap or
in your arms. Use a child restraint
system in the rear seat. For instruc-
tions concerning the installation of
a child restraint system, see “Child
restraint” on page 127 in this Sec-
tion.
Do not put anything or any part of
your body on or in front of the
dashboard or steering wheel pad
that houses the front airbag sys-
tem. They might restrict inflation or
cause death or serious injury as
they are projected rearward by the
force of the deploying airbags. Like-
wise, the driver and front passenger
should not hold objects in their
arms or on their knees.

ing. Do not modify, remove, strike
or open any components such as
the steering wheel pad, steering
wheel, column cover, dashboard
near the front passenger airbag,
front passenger airbag cover, front
passenger airbag or airbag sensor
assembly. Doing so may prevent the
front airbag system from activating
correctly, cause sudden activation
of the system or disable the sys-
tem, which could result in death or
serious injury.
Failure to follow these instructions
can result in death or serious injury.
Consult your Toyota dealer about any
repair and modification.
If you wish to modify your vehicle for
a person with a physical disability,
consult your Toyota dealer. It may
dangerously interfere with the SRS
front airbags operation.NOTICE
Do not perform any of the following
changes without consulting your
Toyota dealer. Such changes can in-
terfere with proper operation of the
SRS front airbag system in some
cases.
Installation of electronic devices
such as a mobile two way radio,
cassette tape player or compact
disc player
Modification of the suspension sys-
tem
Modification of the front end struc-
ture
Attachment of a grille guard (bull
bar, kangaroo bar, etc.), snowplow,
winches or any other equipment to
the front end
Repairs made on or near the front
fenders, front end structure, con-
sole, steering column, steering
wheel or dashboard near the front
passenger airbag
