2) Fuel Shutoff Valve for Fuel Tank
This valve uses an solenoid valve. The main pipe that supplies compressed gas to the engine is connected
to this valve, which opens when the ignition switch is turned ON. If the engine stalls, this valve automati-
cally shuts off the fuel even if the ignition switch is turned ON. The valve reopens upon restarting the
engine.
Also, this valve shuts off the fuel if the SRS airbag is deployed in a collision or if the pressure in the main
pipe becomes abnormally low.
3) Inlet Check Valve
Connected to a filler pipe that guides the fuel that fills through the coupler, the inlet check valve shuts
off by the force of a spring and by the pressure of the gas in the tank.
During filling, the pressure of the filling gas opens the inlet check valve.
4) Relief Valve
A vent tube is connected to this valve.
If the fuel tank is exposed to an abnormally high temperature, this valve opens (by melting) to discharge
the CNG at a predetermined temperature, thus helping prevent the fuel tank from bursting due to the in-
crease in gas pressure.
The discharged CNG is guided under the floor through a vent tube and is released outside of the vehicle.
Coupler
The coupler allows the fuel to be filled when it is connected with a fuel filling nozzle. The coupler has a
built-in check valve to help prevent the CNG from flowing backward.
Manual Shutoff Valve
This valve is mounted below the vehicle floor.
When servicing the vehicle, this valve can be
manually turned 90 degrees to shut off the main
pipe.

Break±in period
Drive gently and avoid high speeds.
Your vehicle does not need an elaborate
break±in. But following a few simple tips
for the first 1600 km (1000 miles) can add
to the future economy and long life of
your vehicle:

Do not drive over 88 km/h (55 mph).

Run the engine at moderate speed be-
tween 2000 and 4000 rpm.

Avoid full±throttle starts.

Try to avoid hard stops during the first
300 km (200 miles).

Do not drive slowly with the manual
transmission in a high gear.

Do not drive for a long time at any
single speed, either fast or slow.

Do not tow a trailer during the first 800
km (500 miles).
Fuel
FUEL TYPE
Your new vehicle must use only un-
leaded gasoline.
To help prevent gas station mix±ups, your
Toyota has a new smaller fuel tank open-
ing. The special nozzle on pumps with
unleaded fuel will fit it, but the larger
standard nozzle on pumps with leaded gas
will not.
At a minimum, the gasoline you use
should meet the specifications of ASTM
D4814 in the U.S.A. and CGSB 3.5±M93
in Canada.
NOTICE
Do not use leaded gasoline. Use of
leaded gasoline will cause the three±
way catalytic converter to lose its ef-
fectiveness and the emission control
system to function improperly. Also,
this can increase maintenance costs.
