CAUTION
After inserting the tab, make sure
the tab and buckle are locked and
that the seat belt extender is not
twisted.
Do not insert coins, clips, etc. in
the buckle as this may prevent you
from properly latching the tab and
buckle.
If the seat belt does not function
normally, immediately contact your
authorized Toyota CNG dealer. Do
not use the seat until the seat belt
is fixed. It cannot protect an adult
occupant or your child from injury.
—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
belt is quickly drawn back in by the re-
tractor so that the belt snugly restrains
the front seat occupants.
The seat belt pretensioners are activated
even with no passenger in the front seat.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, seat belt pretensioner assemblies,
warning light, interconnecting wiring and
power sources. (For details, see “Service
reminder indicators and warning buzzers”
in Chapter 1−5.)

27
The seat belt pretensioner system mainly
consists of the following components and
their locations are shown in the illustra-
tion.
1. Front airbag sensors
2. SRS warning light
3. Seat belt pretensioner assemblies
4. Airbag sensor assembly
The seat belt pretensioner is controlled by
the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor.When a seat belt pretensioner is acti-
vated, an operating noise may be heard
and a small amount of smoke−like gas
may be released. This gas is harmless
and does not indicate that a fire is occur-
ring.
Once the seat belt pretensioner has been
activated, the seat belt retractor remains
locked.
CAUTION
Do not modify, remove, strike or open
the front seat belt pretensioner as-
semblies, airbag sensor or surround-
ing area or wiring. Doing any of
these may cause sudden operation of
the front seat belt pretensioners or
disable the system, which could re-
sult in serious injury.
Failure to follow these instructions
can result in serious injuries.
NOTICE
Do not perform any of the following
changes without consulting your
authorized Toyota CNG dealer. Such
changes can interfere with proper
operation of the seat belt
pretensioners in some cases.
Installation of electronic items such
as a mobile two−way radio, cassette
tape player or compact disc player
Repairs on or near the front seat
belt retractor assemblies
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 or con-
sole

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 airbags
are operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, inflators, warning light, interconnect-
ing wiring and power sources. (For details,
see “Service reminder indicators and
warning buzzers” in Chapter 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.
There may be the case that the SRS air-
bag will not activate with such an impact
in which the occupant wearing the seat
belt correctly would not get serious injury.
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.

31
The SRS airbag system mainly consists 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 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, sensors detect
deceleration and the system triggers the
airbag inflators. Then a chemical reaction
in the inflators momentarily fills the air-
bags 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 minor
skin irritation. Be sure to wash off any
residue as soon as possible to prevent
minor 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 swellings.
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.

Gauges, Meters and
Service reminder
indicators
Fuel gauge
Engine coolant temperature
gauge
Tachometer
Odometer and two trip meters
Service reminder indicators and
warning buzzers
Fuel gauge
Low fuel level
warning light
The gauge works when the ignition
switch is on and indicates the approxi-
mate quantity of fuel remaining in the
tank.
Nearly full—Needle at “F”
Nearly empty—Needle at around 1/5 posi-
tion
It is a good idea to keep the tank over
1/4 full.
This fuel gauge has a non−return type
needle which remains at the last indicated
position when the ignition switch is turned
off.This gauge indicates the amount of fuel
remaining in the tank is calculated from
the pressure of the natural gas and the
temperature inside the tank. The actual
amount may be slightly above or below
that indicated, depending on the outside
temperature and environment.
If the low fuel level warning light comes
on, fill the fuel tank as soon as possible.
If you continue to drive the vehicle after
the low fuel level warning light comes on,
the light will begin to blink, and at the
same time you will not be able to drive
at speeds over 80 km/h (50 mph).
NOTICE
If the low fuel warning light begins to
blink, the fuel tank will soon be
empty. Move to a safe place as soon
as possible.

Odometer and two trip meters
This meter displays the odometer and
two trip meters.
1. Odometer—It shows the total distance
the vehicle has been driven.
2. Two trip meters—They show two differ-
ent distances independently driven
since the last time each trip meter was
set to zero.
You can use one trip meter to calculate
the fuel economy and the other to
measure the distance on each trip. All
trip meter data is cancelled if the elec-
trical power source is disconnected.3. Trip meter reset knob—It can reset the
two trip meters to zero, and also
change the meter display.
To change the meter display, quickly
push and release the knob. The meter
display changes in the order from the
odometer to trip meter A to trip meter
B, then back to the odometer each
time you push.
To reset the trip meter A to zero, dis-
play the meter A reading, then push
and hold the knob until the meter is
set to zero. The same process can be
applied for resetting the trip meter B.(
a)If parking brake
is off, stop and
check.
(b) Fasten seat belt.

below comes on...
(c) Stop and check.
