—Front seat belt pretensioners
The driver and front passenger ’s seat
belt pretensioners are designed to be
activated in response to a severe fron-
tal impact.
When the airbag sensor detects the shock
of a severe frontal impact, the front seat
belts are quickly drawn back in by the
retractors so that the belts snugly restrain
the front seat occupants.
The front seat belt pretensioners are acti-
vated even with no passenger in the front
seat.
Collisions occurring at certain speeds and
angles may cause the seat belt preten-
sioners and SRS airbags not to operate
all together.This indicator comes on when the igni-
tion key is turned to the “ACC” or
“ON” position. It goes off after about
6 seconds. This means the front seat
belt pretensioners are operating proper-
ly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, front seat belt pretensioner assem-
blies, inflators, warning light, interconnect-
ing wiring and power sources. (For details,
see “Service reminder indicators and
warning buzzers” in Section 1−5.)The front seat belt pretensioner system
mainly consists of the following compo-
nents and their locations are shown in the
illustration.
1. Front airbag sensors
2. SRS warning light
3. Front seat belt pretensioner assemblies
4. Airbag sensor assembly
The front seat belt pretensioners are con-
trolled by the airbag sensor assembly. The
airbag sensor assembly consists of a saf-
ing sensor and airbag sensor.

CAUTION
A driver or front passenger 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.This indicator comes on when the igni-
tion key is turned to the “ACC” or
“ON” position. It goes off after about
6 seconds. This means the SRS front
airbags are operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, front seat belt pretensioner assem-
blies, inflators, warning light, interconnect-
ing wiring and power sources. (For details,
see “Service reminder indicators and
warning buzzers” in Section 1−5.)The SRS airbag system is designed to
activate in response to a severe frontal
impact within the shaded area between
the arrows in the illustration.
The SRS airbags will deploy if the severi-
ty of the impact is above the designed
threshold level, comparable to an approxi-
mate 25 km/h (15 mph) collision when
impacting straight into a fixed barrier that
does not move or deform.
If the severity of the impact is below the
above threshold level, the SRS airbags
may not deploy.

The SRS airbag system consists mainly of
the following components, and their loca-
tions are shown in the illustration.
1. Front airbag sensors
2. SRS warning light
3. Airbag module for front passenger
(airbag and inflator)
4. Airbag sensor assembly
5. Airbag module for driver
(airbag and inflator)
The airbag sensor assembly consists of a
safing sensor and airbag sensor.In a severe frontal impact, the sensors
detect deceleration and the system trig-
gers the airbag inflators. Then a chemical
reaction in the inflators quickly fills the
airbags with non−toxic gas to help restrain
the forward motion of the occupants.
When the airbags inflate, they produce a
fairly loud noise and release some smoke
and residue along with non−toxic gas. This
does not indicate a fire. This gas is nor-
mally harmless; however, for those who
have delicate skin, it may cause a minor
skin irritation. Be sure to wash off any
residue as soon as possible to prevent
any potential skin irritation.
Deployment of the airbags happens in a
fraction of a second, so the airbags must
inflate with considerable force. While the
system is designed to reduce serious inju-
ries, it may also cause minor burns or
abrasions and swelling.
Parts of the airbag module (steering wheel
hub, dashboard) may be hot for several
minutes, but the airbags themselves will
not be hot. The airbags are designed to
inflate only once.A crash severe enough to inflate the air-
bags may break the windshield as the
vehicle buckles. In vehicles with a pas-
senger airbag the windshield may also be
damaged by absorbing some of the force
of the inflating airbag.

A warning light turning on briefly during
operation does not indicate a problem.
(h) Open Door Warning Light
This light remains on until all the doors
are completely closed.
(i) Rear Light Failure Warning Light
If this light comes on when the headlight
switch is turned on (at the first or second
clickstop), it indicates that one or more of
the tail lights are burned out.
If it comes on when the brake pedal is
depressed, one or more stop lights are
burned out.
Have defective bulbs replaced as soon as
possible.
(j) SRS Warning Light
This light will come on when the igni-
tion key is turned to the “ACC” or
“ON” position. After about 6 seconds,
the light will go off. This means the
systems of the airbag and front seat
belt pretensioner are operating properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, front seat belt pretensioner assem-
blies, inflators, warning light,
interconnecting wiring and power sources.If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your authorized Toyota
CNG dealer as soon as possible to ser-
vice the vehicle.
The light does not come on when the
ignition key is turned to the “ACC” or
“ON” position or remains on.
The light comes on or flashes while
driving.
(k) Low Windshield Washer Fluid Level
Warning Light
The light warns that the windshield washer
fluid level is too low. Add washer fluid at
your earliest opportunity. (For instructions,
see “Adding washer fluid” in Section 7−3.)
(l) Key Reminder Buzzer
This buzzer reminds you to remove the
key when you open the driver’s door with
the ignition key in the “ACC” or “LOCK”
position.CHECKING SERVICE REMINDER
INDICATORS (except the low fuel level
warning light and low windshield
washer fluid level warning light)
1. Apply the parking brake.
2. Open one of the doors.
The open door warning light should
come on.
3. Close the door.
The open door warning light should go
off.
4. Turn the ignition key to “ACC”.
The SRS warning light should come on.
It goes off after about 6 seconds.
5. Turn the ignition key to “ON”, but do
not start the engine.
All the service reminder indicators ex-
cept the open door warning light and
SRS warning light should come on. The
“ABS” warning light goes off after a
few seconds.
If any service reminder indicator or warn-
ing buzzer does not function as described
above, have it checked by your authorized
Toyota CNG dealer as soon as possible.

NOTICE
Do not damage the tank. If the tank
is damaged, have it inspected by
your authorized Toyota CNG dealer
as soon as possible.
Do not expose the tank to chlorine,
oxygen or other corrosive liquids.
This tank is intended for use with
compressed natural gas—the fuel
for this vehicle. Do not use it for
any other purpose.
SERVICE PRESSURE:
24800 kPa (3600 psig)
Equivalent gasoline capacity:
43 L (11.4 gal., 9.5 lmp.gal.)
Water volume:
135 L (35.7 gal., 29.7 lmp.gal.)
—Fuel shut off system
If the engine stalls, fuel flow from the tank
is automatically shut off. When restarting
the engine after fuel flow is shut off, turn
the ignition switch to “ACC” or “LOCK”
once and then start it. The fuel flow from
the tank will also be shut off automatically
when an airbag inflates upon collision or
if the piping is disconnected.
CAUTION
If the vehicle is involved in a colli-
sion and there is a chance that there
may be fuel leakage, never restart the
engine. Ignition of leaked natural gas
may cause death or serious injury.
Manual shutoff valve
This valve is for manually shutting off
fuel from the tank. It is usually left
open. Use this valve to shut off fuel if
you suspect that the fuel is leaking or
after you have been involved in a colli-
sion.
Refer to “If you suspect the fuel is
leaking” in Section 4 for how to operate
the valve.
Operation in foreign countries
If you plan to drive your Toyota in
another country...
First, comply with the vehicle registration
laws.
Second, confirm the availability of the cor-
rect fuel and filling nozzles.
