1999 TOYOTA CAMRY CNG open gas tank

14
When refueling, you must use a special
nozzle that meets ANSI/AGA
NGV−1−1994 standards.
There are three types of nozzles. Use
a P36 type nozzle for this vehicle. If a
P36 nozzle is not available at a nearby
CNG station, you may use another type
of nozzle, but you cannot expect to get
a completely full tank with it.
For your safety, ask and follow the in-
structions at the refueling station when
refueling.
Before starting to refuel, wipe off mud
or dirt that may be deposited around
the fuel receptacle.
You will hear a chattering noise from the
tank when it is being filled, but this is
quite normal.
If you hear fuel leaking from the fuel re-
ceptacle, stop refueling immediately and
have your authorized Toyota CNG dealer
check the fuel receptacle.
For information on CNG stations, refer to
the station “Refueling station information”
on page iii in the beginning of this manu-
al.CAUTION
In order to safety refuel and avoid
serious personal injury, ask the
CNG station staff to refuel the ve-
hicle with CNG for you.
Do not start the engine while refuel-
ing. As the natural gas is flam-
mable, an explosion or a fire could
occur. Also, do not smoke or allow
open flames when refueling.
If you smell or hear fuel leaking
while refueling, immediately stop re-
fueling. Do not refuel it until after
the leak has been repaired.
There are two ways of natural gas re-
fueling: high and low speed. This manu-
al explains typical high speed refueling.
As for the low speed refueling method,
follow the instructions provided by the
manufacturer for the refueling equipments.
1. To open the refueling plug door, pull
the lever up.
When refueling, turn off the engine.

The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest authorized Toyota CNG dealer
or repair shop.
NOTICE
Do not continue driving if the engine
drive belt is broken or loose.
(d) Malfunction Indicator Lamp
This lamp warns that there is a problem
somewhere in your engine or automatic
transmission electrical system.
If it comes on while you are driving, have
your vehicle checked/repaired by your au-
thorized Toyota CNG dealer as soon as
possible.
(e) Low Fuel Level Warning Light
This light comes on when the amount of
natural gas remaining in the tank drops to
about 1/5.
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).When the outside temperature is below
−30°C (−22°F), the fuel gauge may indi-
cate an amount less than actual amount
and the indicator may come on.
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.
(f) Low Oil Pressure Warning Light
This light warns that the engine oil pres-
sure is too low.
If it flickers or stays on while you are
driving, pull off the road to a safe place
and stop the engine immediately. Call your
authorized Toyota CNG dealer or qualified
repair shop for assistance.
The light may occasionally flicker when
the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when
the engine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to
indicate low oil level, and the oil level
must be checked using the level dipstick.
NOTICE
Do not drive the vehicle with the
warning light on—even for one block.
It may ruin the engine.
(g) “ABS” Warning Light
This light warns that there is a problem
somewhere in your anti−lock brake sys-
tem.
If the light comes on while you are driv-
ing, have your vehicle checked by your
authorized Toyota CNG dealer as soon as
possible.
The light will come on when the ignition
key is turned to the “ON” position. After
a few seconds, the light will go off.
When the “ABS” warning light is on (and
the brake system warning light is off), the
brake system operates conventionally but
anti−lock brake system is not assisting
brake performance so that the wheels can
lock−up during sudden braking or braking
on slippery road surfaces.
(h) Open Door Warning Light
This light remains on until all the doors
and back door are completely closed.

CAUTION
This tank contains high pressure
flammable natural gas. You must
ensure that the tank is checked and
inspected and properly maintained,
as well as avoid overfilling or dril-
ling holes in it, or damaging it in
any other way because death or se-
rious injury may result.
Do not allow any person other than
a qualified technician to remove
this tank from the vehicle. If residu-
al gas in the tank is not discharged
correctly, static electricity may be
ignited, causing fire or explosion.
Do not leave the fuel tank where
the temperature can exceed 80C
(176F). The tank’s built−in pressure
relief device may open and release
all the fuel from under the floor.
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 shut off 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 Part 4 for how to operate the
valve.

143
If you smell fuel or hear the sound of
leaking fuel at anytime or if your ve-
hicle is involved in an accident, imme-
diately close the manual shut off valve
to shut the fuel off.
The manual shut off valve is intended to
shut the fuel from the tank off. Normally
it is left open.
To close: Turn the lever clockwise 90°.
To open: Turn the lever counterclockwise
90°.
If you suspect a fuel leakage, close the
manual shut off valve and have your ve-
hicle serviced by your authorized Toyota
CNG dealer as soon as possible.
If, due to a collision or similar circum-
stances, the fuel system may be dam-
aged, close the manual shut off value,
and contact your authorized Toyota CNG
dealer to have the fuel system checked
for fuel leakage.CAUTION
If you smell or hear fuel leaking,
shut off the fuel system immediate-
ly. If leaking fuel is ignited, an ex-
plosion or fire could occur, causing
death or serious injury.
Do not inhale a large amount of
leaked fuel. Inhaling the natural gas
continuously may cause the lack of
oxygen in your body.
If you suspect a fuel leakage, do
not park the vehicle in an enclosed
area such as a garage, or the
leaked fuel may fill the area and
cause a fire or explosion.
If you suspect the fuel is leaking
while refueling, stop refueling im-
mediately. If leaking fuel is ignited,
an explosion or fire could occur,
causing death or serious injury.
