caused the warning light to come on,
check to see that the parking brake is
fully released.
If the brake fluid level is low...
At a safe place, test your brakes by start-
ing and stopping.
If you judge that the brakes still work
adequately, drive cautiously to the
nearest authorized Toyota CNG dealer
or shop for repairs.
If the brakes are not working, have the
vehicle towed in for repairs. (For tow-
ing information, see Part 4.)
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
If the brake fluid level is correct...
Have the warning system checked by your
authorized Toyota CNG dealer.
(b) Seat Belt Reminder Light and Buzz-
er
This light and buzzer remind you to
buckle up the driver’s seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light and buzzer
come on if the driver’s seat belt is not
fastened. Unless the driver fastens the
belt, the light stays on and the buzzer
stops after about 4 to 8 seconds.
(c) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.

67
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.

key is turned to the “ON” position. After
a few seconds, the light will go off.
When the “ABS” warning light is on (and

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.

This light remains on until all the doors
and back door are completely closed.

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

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.
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

The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an express way, making it
appear that oil is excessively consumed
after driving at high speeds.
IMPORTANCE OF ENGINE OIL LEVEL
CHECK
One of the most important points in prop-
er vehicle maintenance is to keep the en-
gine oil at the optimum level so that oil
function will not be impaired. Therefore, it
is essential that the oil level be checked
regularly. Toyota recommends that the oil
level be checked every time you refuel
the vehicle.
NOTICE
Failure to check the oil level regularly
could lead to serious engine trouble
due to insufficient oil.
For detailed information on oil level check,
see “Checking the engine oil level” in
Chapter 7−2.
Your engine is fitted with twin ground
electrode platinum−tipped spark plugs.
NOTICE
For your engine performance, use
only twin ground electrode platinum−
tipped spark plugs specially designed
for CNG vehicles. Spark plugs for
gasoline−engined vehicles cannot be
used for your vehicle.
Brake system
TANDEM MASTER CYLINDER BRAKE
SYSTEM
The tandem master cylinder brake system
is a hydraulic system with two separate
sub−systems. If either sub−system should
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will be longer. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses engine vacuum to
power−assist the brakes. If the engine
should quit while you are driving, you can
bring the vehicle to a stop with normal
pedal pressure. There is enough reserved
vacuum for one or two stops—but no
more!

“ABS” warning light
The light comes on when the ignition key
is turned to the “ON” position. After a few
seconds, the light will go off.
If either of the following conditions occurs,
this indicates a malfunction somewhere in

The light comes on while driving.Even if the anti−lock brake system should
fail, the brake system will still operate
conventionally. However, when the “ABS”
warning light is on (and the brake system
warning light is off), the 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. Have your vehicle checked
by your authorized Toyota CNG dealer as
soon as possible.
Brake pad wear limit indicators
The brake pad wear limit indicators on
your disc brakes give a warning noise
when the brake pads are worn to where
replacement is required.
If you hear a squealing or scraping noise
while driving, have the brake pads
checked and replaced by your authorized
Toyota CNG dealer as soon as possible.
Expensive rotor damage can result if the
pads are not replaced when necessary.
