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 427 in Section 72.
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 324 in
Section 110.

The curtain shield airbags may not acti-
vate if the vehicle is subjected to a
collision from the side at certain
angles, or a collision to the side of the
vehicle body other than the passenger
compartment as shown in the illustra-
tion.
The curtain shield airbags are designed to
inflate when the passenger compartment
area suffers a severe impact from the
side or vehicle rollover.
Always wear your seat belts properly.
The angle of
vehicle tip−up
is marginal Skidding vehicle
hitting a curb
stone
The curtain shield airbags may inflate
if the angle of vehicle tipup is margin-
al or if the skidding vehicle’s tires hit
a curb stone laterally as shown in the
illustration.
Collision from
the front
Collision from
the rear
Pitch end over end
The curtain shield airbags are not gen-
erally designed to inflate if the vehicle
is involved in a front or rear collision,
if it pitches end over end, or if it is
involved in a lowspeed side collision.

Do not hook a hanger, heavy or
sharp pointed objects on the coat
hook. If the curtain shield airbag
inflates, those items will be thrown
away with great force or the curtain
shield airbag may not activate cor-
rectly, resulting in death or serious
injury. When you hang clothes,
hang them on the coat hook direct-
ly.
Do not use seat accessories which
cover the parts where the side air-
bags inflate. Such accessories may
prevent the side airbags from acti-
vating correctly, causing death or
serious injury.
Do not modify or replace the seats
or upholstery of the seats with side
airbags. Such changes may prevent
the side airbag system from activat-
ing correctly, disable the system or
cause the side airbags to inflate ac-
cidentally, resulting in death or seri-
ous injury.
Do not disassemble or repair the
front pillars and roof side rail con-
taining the curtain shield airbags.
Such changes may disable the sys-
tem or cause the curtain shield air-
bags to inflate accidentally, result-
ing in death or serious injury.
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.
Do not use tires or wheels other
than the manufacturer ’s recom-
mended size. Such a use may cause
the curtain shield airbags to inflate
accidentally, which could result in
death or serious injury. For details,
see “Checking and replacing tires”
on page 427 in Section 72.
Do not place luggage heavier than
specified on the roof luggage carri-
er. Such luggage may cause the
curtain shield airbags to inflate ac-
cidentally, which could result in
death or serious injury. For details,
see “Roof luggage carrier” on page
324 in Section 110.
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 physical disability, con-
sult your Toyota dealer. It may dan-
gerously interfere with the SRS side
airbags and curtain shield airbags op-
eration.

(l) SRS Warning Light
This indicator comes on when the igni-
tion key is turned to the “ON” position.
It goes off after about 6 seconds. This
means the SRS airbags and seat belt
pretensioners are operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sen-
sors, curtain shield airbag sensors, driv-
er ’s seat position sensor, driver ’s seat belt
buckle switch, front passenger occupant
classification system and indicator light,
front passenger ’s seat belt buckle switch,
seat belt pretensioner assemblies, inflat-
ors, “RSCA OFF” indicator light, intercon-
necting wiring and power sources.
If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Toyota dealer as soon as possible.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion or remains on for more than 6
seconds or flashes.
The light comes on or starts flashing
while driving. The SRS warning light will come on and
front passenger occupant classification in-
dicator light will indicate “OFF” if there is
a malfunction in the front passenger occu-
pant classification system.
(m) Automatic Transmission Fluid
Temperature Warning Light
(fourwheel drive models)
This light warns that the automatic trans-
mission fluid temperature is too high.
If this light comes on while you are driv-
ing, slow down and pull off the road. Stop
the vehicle at a safe place and put the
selector lever in “P”. With the engine id-
ling, wait until the light goes off. If the
light goes off, you may start the vehicle
again. If the light does not go off, call a
Toyota dealer or qualified repair shop for
assistance.
NOTICE
Continued driving with the warning
light on may damage the automatic
transmission.
(n) Low Tire Pressure Warning Light
This light warns that the tire pressure of
one or more of your tires (including the
spare tire) is low. The light comes on
when the ignition key is turned to the
“ON” position. It goes off after a few sec-
onds. This indicates that the tire pressure
warning system is functioning properly.
If the warning light comes on, stop your
vehicle in a safe place as soon as pos-
sible and check that the inflation pressure
of all tires (including the spare tire) is as
specified on the tire and loading informa-
tion label. (See “Checking tire inflation
pressure” on page 425 in Section 7− 2.)
The light should go off a few minutes after
the tire pressure is adjusted.
If the warning light blinks, the tire pres-
sure warning system may be malfunction-
ing. Contact your Toyota dealer.
For details, see “Tire pressure warning
system” on page 190 in Section 1 −7.

(g) Rear height control failure warning
If there is a problem somewhere in the
rear height control air suspension, the “N”
mode is automatically selected. If this oc-
curs, the height control “OFF” indicator
light blinks and the vehicle height control
cannot be activated until the malfunction
is corrected. If this is the case, bring your
vehicle to your Toyota dealer as soon as
possible and have it checked. The tire pressure warning system is de-
signed to provide warning when tire
inflation pressure of one or more of
your tires (including the spare tire) is
low. The low tire pressure warning light
comes on to inform you that low tire
inflation pressure may hamper driving.

LOW TIRE PRESSURE WARNING LIGHT
This light comes on when the ignition key
is turned to the “ON” position. It goes off
after a few seconds. This indicates that
the tire pressure warning system is func-
tioning properly.
If the low tire pressure warning light
comes on or blinks, do the following.
If the warning light comes on:
Stop your vehicle in a safe place as
soon as possible and check that the
inflation pressure of all tires (including
the spare tire) is as specified on the
tire and loading information label. (See
“Checking tire inflation pressure” on
page 425 in Section 72.) If the warning
light comes on even after tire inflation
pressure adjustment, you may have a
flat tire. If you have a flat tire, replace
it with the spare tire. For details, see
“If you have a flat tire” on page 379 in
Section 4.
The warning light goes off a few minutes
after air is put into the deflated tire.
This warning light may turn on due to
natural causes such as natural air leaks
or tire pressure changes caused by tem-
perature. In this case, adjusting the tire
pressure will turn off the warning light.CAUTION
When the tire pressure warning light
comes on, observe the following in-
structions:
Depending on the conditions, re-
duce to an appropriate speed as
soon as possible.
Adjust the tire pressure to the spe-
cified level as soon as possible.
Avoid abrupt steering wheel maneu-
vering and braking. Tire deteriora-
tion may reduce steering wheel con-
trol and brake effectiveness. This
may lead to serious injury or death.
The tire pressure warning system
may not activate immediately if sud-
den bursts of air leakage occur.
NOTICE
Do not use liquid sealants for a flat
tire as air pressure sensors will be
damaged.
 When the tires must be repaired or
replaced, have them repaired or re-
placed by the nearest Toyota dealer
or authorized tire dealer. The tire
pressure sensors will be affected by
the installation or removal of tires.
 The tire pressure warning system is
not to be used as a substitute for
regular inspections. Be sure to
check the air pressure in the tires
on a regular basis.
 When the tires must be replaced,
replace the grommets for air pres-
sure sensors as well.

If the warning light blinks:
The tire pressure warning system may
be malfunctioning. Contact your Toyota
dealer.
SYSTEM MALFUNCTION
The tire pressure warning system does
not function properly under certain cir-
cumstances. In the following cases, the
low tire pressure warning light may not
come on even if the tire inflation pres-
sure is low, or it may come on when
the tire inflation pressure is actually
normal.
Electric devices or facilities using simi-
lar radio wave frequencies are nearby.
A radio set to similar frequencies is in
use.
A lot of snow or ice covers the ve-
hicle, in particular, around the wheels
or wheel housings.
The tires are not equipped with an air
pressure sensor.
Snow tires or tire chains are used.
Non−genuine Toyota wheels are used.
The sensor battery is expired.
Radio waves from the air pressure sen-
sor installed on the spare tire cannot
be received.
CAUTION
The use of nongenuine wheels will
cause the air pressure sensors to
transmit the electronic code in dif-
ferent manner, resulting in the sys-
tem failure.
The use of different type of tires
with genuine wheels may also
cause the malfunction of the sys-
tem.
CAUTION
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
or tire inflation pressure label (tire
and load information label). (If your
vehicle has tires of a different size
than the size indicated on the vehicle
placard or tire inflation pressure label
(tire and load information label), you
should determine the proper tire infla-
tion pressure for those tires.)

’06 4Runner_U (L/O 0508)
193
As an added safety feature, your ve-
hicle has been equipped with a tire
pressure monitoring system (TPMS
tire pressure warning system) that il-
luminates a low tire pressure telltale
(low tire pressure warning light) when
one or more of your tires is signifi-
cantly underinflated. Accordingly,
when the low tire pressure telltale
(low tire pressure warning light) illu-
minates, you should stop and check
your tires as soon as possible, and
inflate them to the proper pressure.
Driving on a significantly underin-
flated tire causes the tire to overheat
and can lead to tire failure. Under
inflation also reduces fuel efficiency
and tire tread life, and may affect the
vehicle’s handling and stopping abili-
ty.
Please note that the TPMS (tire pres-
sure warning system) is not a substi-
tute for proper tire maintenance, and
it is the driver ’s responsib ility to
maintain correct tire pressure, even if
underinflation has not reached the
level to trigger illumination of the
TPMS low tire pressure telltale (low
tire pressure warning light).For vehicles sold in U.S.A.
