The oil pressure gauge indicates engine
oil pressure when the engine switch is
on. Check it while driving to make sure
that the needle is in the proper range.
If the oil pressure should stay below the
normal range, pull off the road to a safe
place and stop the engine immediately.
Call a Toyota dealer or qualified repair
shop for assistance.
Oil pressure may not build up when the
oil level is too low. The oil pressure
gauge is not designed to indicate oil level,
and the oil level must be checked using
the level dipstick.
NOTICE
Do not drive the vehicle with the oil
pressure below the normal range until
the cause is fixed—it may ruin the
engine.

Automatic transmission fluid tempera-
ture gauge indicates automatic trans-
mission fluid temperature when the en-
gine switch is on. Check it while
driving to make sure that the needle is
in the proper range.
The gauge displays the current tempera-
ture of the automatic transmission fluid.
The gauge informs the driver of changes
in the automatic transmission fluid temper-
ature especially if it becomes too high
while towing a heavy trailer or hauling a
heavy load.
If the needle reads high range while you
are driving, slow down and pull off the
road. Stop the vehicle at a safe place and
put the selector lever in “P”. With the
engine idling, wait until the needle reads
below the high range. If the needle reads
below the high range, you may start the
vehicle again. If the needle reads the high
range, call a Toyota dealer or qualified
repair shop for assistance.
NOTICE
Continued driving with reading in the
high range may damage the automatic
transmission.

The voltmeter tells whether the battery
is charged or discharged. Check it
while the engine is running—the needle
should always indicate as shown above.
If the needle reads below or above the
normal range while the engine is running,
it indicates the charging system needs im-
mediate repair.
However, it is normal for the needle to
drop below the normal range during en-
gine starting.

(a) Brake System Warning Light and
buzzer
This light comes on in the following cases
when the engine switch is in the “ON”
position.
When the parking brake is applied...
This light comes on for a few seconds
when the engine switch is turned to the
“ON” position even after the parking brake
is released.
When the brake fluid level is low...
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
Have your vehicle checked at your
Toyota dealer in the following case:
The light does not come on even if the
parking brake is applied when the engi-
ne switch is in the “ON” position.
The light does not come on even if the
engine switch is turned on with the
parking brake released.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If either of the following conditions
occurs, immediately stop your vehicle
at a safe place and contact your
Toyota dealer.
The light does not turn off even
after the parking brake is released
while the engine is running.
In this case, the brakes may not
work properly and your stopping
distance will become longer. De-
press the brake pedal firmly and
bring the vehicle to an immediate
stop.
The brake system warning light re-
mains on together with the “ABS”
warning light.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely un-
stable during braking.
(b) Driver’s Seat Belt Reminder Light and Buzzer
The light and buzzer act as a reminder to
buckle up the driver’s seat belt.
Once the engine switch is turned to “ON”
or “START”, the reminder light flashes and
buzzer sounds if the driver ’s seat belt is
not fastened. Unless the driver fastens the
belt, the light continues flashing and the
buzzer stops after about 4 to 8 seconds.
If the vehicle speed rises above 20 km/h
(12 mph) with the seat belt unfastened,
the buzzer will sound for about 10 sec-
onds. Then, if the seat belt is still unfas-
tened, the buzzer will sound in a different
tone for 20 seconds. Even if the vehicle
speed drops below 20 km/h (12 mph), the
buzzer will continue to sound. To stop the
buzzer, fasten the seat belt. If the buzzer
still sounds, make sure the front passen-
ger ’s seat belt is fastened.
