130GAUGES, METERS AND SERVICE REMINDER INDICATORS
(c) Front Passenger ’s Seat Belt
Reminder Light and Buzzer
The light and buzzer act as a reminder to
have the front passenger buckle up the
seat belt.
Once the engine switch is turned to “ON”
or “START”, the reminder light flashes if
a passenger sits in the front passenger
seat and does not fasten the seat belt.
Unless the front passenger fastens the
belt, the light continues flashing.
If the vehicle speed rises above 20 km/h
(12 mph) with the seat belt unfastened,
the buzzer will sound for 30 seconds.
Then, if the seat belt is still unfastened,
the buzzer will sound in a different tone
for 90 more 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 driver ’s seat
belt is fastened.
If luggage or other load is placed on the
front passenger seat, depending on its
weight and how it is placed on the seat,
built−in sensors in the seat cushion may
detect the pressure, causing the reminder
light to flash and buzzer to sound.
(d) Charging System Warning Light
This warning light comes on when the
engine switch is turned to the “ON” posi-
tion, and goes off when the engine is
started.
When there are problems in the charging
system while theengine is running, the
warning light comes on.
NOTICE
When the charging system warning
light comes on while the engine is
running, malfunctions such as the en-
gine drive belt being broken may have
occurred. If the warning light comes
on, immediately stop the vehicle in a
safe place and contact any authorized
Toyota dealer or repairer, or another
duly qualified and equipped profes-
sional.
(e) Low Engine Oil Pressure Warning
Light
This light warns that the engine oil pres-
sure is too low.
If the engine oil pressure warning light
comes on, pull off the road to a safe
place and stop the engine immediately.
Call any authorized Toyota dealer or re-
pairer, or another duly qualified and
equipped professional, for assistance. The
“STOP” warning light also comes on at
thesametime.
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 engine
oil level is extremely low. It is not de-
signed to indicate low engine oil level, and
the engine oil level must be checked us-
ing the level dipstick.
NOTICE
Do not drive the vehicle with the
warning light on—even for one block.
It may ruin the engine.

224IN CASE OF AN EMERGENCY
If the cause of the battery discharging is
not apparent (for example lights left on)
you should have it checked at any
authorized Toyota dealer or repairer, or
another duly qualified and equipped
professional.
If the first start attempt is not success-
ful...
Check that the clamp on the jumper
cables are tight. Recharge the discharged
battery with the jumper cables connected
for several minutes and restart your en-
gine in the normal way.
If another attempt is not successful, the
battery may be depleted. Have it checked
at any authorized Toyota dealer or repair-
er, or another duly qualified and equipped
professional.If your engine stalls while driving...
1. Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see “If your
vehicle will not start” on page 220 in this
Section.
CAUTION
If the engine is not running, the pow-
er assist for the brakes will not work
so braking will be much harder than
usual.

Terminals
Hold−down clamp
Check the battery for corroded or loose
terminal connections, cracks, and a
loose hold−down clamp.
a. If the battery is corroded, wash it off
with a solution of warm water and bak-
ing soda. Coat the outside of the termi-
nals with grease to prevent further cor-
rosion.
b. If the terminal connections are loose,
tighten their clamp nuts—but do not
overtighten.
c. Tighten the hold−down clamp only
enough to keep the battery firmly in
place. Overtightening may damage the
battery case.
NOTICE
zBe sure the engine and all accesso-
ries are off before performing main-
tenance.
zWhen checking the battery, remove
the ground cable from the negative
terminal (“−” mark) first and rein-
stall it last.
zBe careful not to cause a short cir-
cuit with tools.
zTake care no solution gets into the
battery when washing it.

Battery recharging precautions
During recharging, the battery is pro-
ducing hydrogen gas.
Therefore, before recharging:
1. If recharging with the battery installed
on the vehicle, be sure to turn the
engine switch to the “LOCK” position
and then disconnect the ground cable.
2. Be sure the power switch on the re-
charger is off when connecting the
charger cables to the battery and when
disconnecting them.
CAUTION
DAlways charge the battery in an un-
confined area. Do not charge the
battery in a garage or closed room
where there is not sufficient ventila-
tion.
DOnly do a slow charge (5 A or
less). Charging at a quicker rate is
dangerous. The battery may ex-
plode, causing personal injuries.
NOTICE
Never recharge the battery while the
engine is running. Also, be sure all
accessories are turned off.
