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
The light comes on with the ignition key
turned to “ON”. If the anti−lock brake sys-
tem works properly, the light goes out
after a few seconds. Thereafter, if the
system malfunctions, the light comes on.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti−lock brake system does not operate,
but the brake system still operates con-
ventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti−lock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces.
If the following conditions occur, 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 service the vehicle.
The light does not come on with the
ignition key turned to “ON”, or remains
on.
The light comes on while driving.If the light lit during driving goes out and

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, seat belt pretensioner assemblies,
inflators, warning light, interconnecting wir-
ing and power sources.

Have the fuel system checked and main-
tained by your authorized Toyota CNG
dealer.
—Fuel tank
The fuel tank on your vehicle conforms
to ANSI/AGA NGV−2, NFPA−52 and DOT
NHTSA FMVSS 304 safety standards.
Removal, servicing, discharge of fuel
and disposal of the tank should only be
done by a qualified technician as pre-
scribed by the fuel control regulation of
NFPA−52, and all applicable federal,
state and local regulations.
Have the fuel tank inspected at the
interval listed in the “Scheduled
Maintenance Guide”. The fuel tank also
requires inspection if the vehicle is
involved in a collision or fire hazard.
Warning labels on the fuel tank and the
engine compartment indicate the ser-
vice limit date of the tank. Do not re-
move or paint over the labels.
See instructions on fuel
container for inspection
and service life.
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.

Anti−lock brake system is not de-
signed to shorten the stopping dis-
tance: Always drive at the moderate
speed and maintain a safe distance
from the vehicle in front of you.
Compared with vehicles not fitted
with an anti−lock brake system, your
vehicle may require a longer stopping
distance in the following cases:
Driving on rough, gravel or snow−
covered roads.
Driving with tire chains installed.
Driving over the steps such as the
joints on the road.
Driving on roads where the road
surface is pitted or has other differ-
ences in surface height.
Install all 4 tires of specified size at
designated pressure: The anti−lock
brake system detects vehicle speeds
using the speed sensors for respec-
tive wheels’ turning speeds. The use
of tires other than specified may fail
to detect the accurate turning speed,
resulting in a longer stopping dis-
tance.
“ABS” warning light
The light comes on when the ignition key
is turned to the “ON” position. If the anti−
lock brake system works properly, the
light goes out after a few seconds. There-
after, if the system malfunctions, the light
comes on.

Check the condition of the battery and
cables.
Cold temperatures reduce the capacity of
any battery, so it must be in top shape
to provide enough power for winter start-
ing. Section 7−3 tells you how to visually
inspect the battery. Your authorized Toyota
CNG dealer and most service stations will
be pleased to check the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See Section 7−2 for recommended viscos-
ity. Leaving a heavy summer oil in your
vehicle during winter months may cause
harder starting. If you are not sure about
which oil to use, call your authorized
Toyota CNG dealer—he will be pleased to
help.
Keep the door locks from freezing.
Squirt lock de−icer or glycerine into the
locks to keep them from freezing. To open
a frozen look, try heating the key before
inserting it.
Use a washer fluid containing an anti-
freeze solution.
This product is available at your autho-
rized Toyota CNG dealer and most auto
parts stores. Follow the manufacturer ’s
directions for how much to mix with water.NOTICE
Do not use engine antifreeze or any
other substitute because it may dam-
age your vehicle’s paint.
Do not use your parking brake when
there is a possibility it could freeze.
When parking, put the transmission into
“P” and block the rear wheels. Do not use
the parking brake, or snow or water accu-
mulated in and around the parking brake
mechanism may freeze, making it hard to
release.
Keep ice and snow from accumulating
under the fenders.
Ice and snow built up under your fenders
can make steering difficult. During bad
winter driving, stop and check under the
fenders occasionally.
Depending on where you are driving,
we recommend you carry some emer-
gency equipment.
Some of the things you might put in the
vehicle are tire chains, window scraper,
bag of sand or salt, flares, small shovel,
jumper cables, etc.
Trailer towing
Your vehicle is designed primarily as a
passenger−carrying vehicle. Towing a
trailer will have an adverse effect on
handling, performance, braking, durability
and driving economy (fuel consumption,
etc.). Your safety and satisfaction depend
on the proper use of correct equipment
and cautious driving habits. For your
safety and the safety of others, you must
not overload your vehicle or trailer. Toyota
warranties do not apply to damage or
malfunction caused by towing a trailer for
commercial purposes. Ask your authorized
Toyota CNG dealer for further details
before towing.
WEIGHT LIMITS
Before towing, make sure the total trailer
weight, gross vehicle weight, gross axle
weight and trailer tongue load are all with-
in the limits.
The total trailer weight and tongue load
can be measured with platform scales
found at a highway weighing station, build-
ing supply company, trucking company,
junk yard, etc.

Before making these checks, make sure
you have followed the correct starting pro-
cedure given in “How to start the engine”
in Section 3 and that you have sufficient
fuel.
If the engine is not turning over or is
turning over too slowly—
1. Check that the battery terminals are
tight and clean.
2. If the battery terminals are O.K., switch
on the interior light.
3. If the light is out, dim or goes out
when the starter is cranked, the battery
is discharged. You may try jump start-
ing. See “(b) Jump starting” for further
instructions.
If the light is O.K., but the engine still will
not start, it needs adjustment or repair.
Call your authorized Toyota CNG dealer or
a qualified repair shop.
NOTICE
Do not pull− or push−start the ve-
hicle. It may damage the vehicle or
cause a collision when the engine
starts. Also the three−way catalytic
converter may overheat and become a
fire hazard.
If the engine turns over at its normal
speed but will not start—
1. Check that all the push−on connectors
are tight. (For example, connectors at
the spark plugs, ignition coil and/or dis-
tributor)
2. If the engine still does not start, manu-
al shutoff valve may be closed. Open
the manual shutoff valve. (See “If you
suspect the fuel is leaking” in this sec-
tion.)
At temperature below −15°C (5°F), even if
you follow the above procedure, your ve-
hicle may not start because of a frozen
fuel injector. Call your authorized Toyota
CNG dealer.
CAUTION
If the engine does not start and the
low fuel level warning light is blink-
ing, fuel may be leaking. Contact your
authorized Toyota CNG dealer immedi-
ately.
(b) Jump starting
To avoid serious personal injury and
damage to your vehicle which might re-
sult from battery explosion, acid burns,
electrical burns, or damaged electronic
components, these instructions must be
followed precisely.
If you are unsure about how to follow this
procedure, we strongly recommend that
you seek the help of a competent me-
chanic or towing service.
CAUTION
Batteries contain sulfuric acid
which is poisonous and corrosive.
Wear protective safety glasses when
jump starting, and avoid spilling
acid on your skin, clothing, or ve-
hicle.
If you should accidentally get acid
on yourself or in your eyes, remove
any contaminated clothing and flush
the affected area with water imme-
diately. Then get immediate medical
attention. If possible, continue to
apply water with a sponge or cloth
while enroute to the medical office.
If your vehicle will not start—
