(b) Driver’s Seat Belt Reminder Light
and Buzzer
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 flashes and
buzzer come on if the driver’s seat belt
is not fastened. Unless the driver fastens
the belt, the light keeps on flashing and

er, if a front passenger uses an additional
seat cushion, the light may not flash even
when the seat belt is not buckled up.
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 come on. (d) 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.
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 Toyota dealer or repair shop.
NOTICE

drive belt is broken or loose.
(e) Low Engine 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 a
Toyota 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

(l) SRS Warning Light
This light will come on when the igni-
tion key is turned to the “ON” position.
After about 6 seconds, the light will go
off. This means the system of the air-
bag and front seat belt pretensioner are
operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sen-
sors, curtain shield airbag sensors, driv-
er ’s seat position sensor, driver ’s seat belt
buckle switch, front seat belt pretensioner
assemblies, inflators, warning light, “RSCA
OFF” indicator light, interconnecting wiring
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 Toyota dealer as
soon as possible to service the vehicle.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion or remains on.
The light comes on or flashes while

again. If the light does not go off, call a
Toyota dealer or qualified repair shop for
assistance.
NOTICE
Continued driving with the warning
light on may damage the automatic
transmission.
(n) Low Tire Pressure Warning Light
This light warns that the tire pressure of
one or more of your tires (including the
spare tire) is low. The light comes on
when the ignition key is turned to the
“ON” position. It goes off after a few sec-
onds. This indicates that the tire pressure
warning system is functioning properly.
If the warning light comes on, stop your
vehicle in a safe place as soon as pos-
sible and check that the inflation pressure
of all tires (including the spare tire) is as
specified on the tire and loading informa-
tion label. (See “Checking tire inflation
pressure” on page 368 in Section 7− 2.)
The light should go off a few minutes after
the tire pressure is adjusted.
If the warning light blinks, the tire pres-
sure warning system may be malfunction-
ing. Contact your Toyota dealer.
For details, see “Tire pressure warning
system” on page 183 in Section 1 −7.

NOTICE
Do not use liquid sealants for a flat
tire as air pressure sensors will be
damaged.
 When the tires must be repaired or
replaced, have them repaired or re-
placed by the nearest Toyota dealer
or authorized tire dealer. The tire
pressure sensors will be affected by
the installation or removal of tires.
 The tire pressure warning system is
not to be used as a substitute for
regular inspections. Be sure to
check the air pressure in the tires
on a regular basis.
 When the tires must be replaced,
replace the grommets for air pres-
sure sensors as well.
If the warning light blinks:
The tire pressure warning system may
be malfunctioning. Contact your Toyota
dealer.
SYSTEM MALFUNCTION
The tire pressure warning system does
not function properly under certain cir-
cumstances. In the following cases, the
low tire pressure warning light may not
come on even if the tire inflation pres-
sure is low, or it may come on when
the tire inflation pressure is actually
normal.
Electric devices or facilities using simi-
lar radio wave frequencies are nearby.
A radio set to similar frequencies is in
use.
A lot of snow or ice covers the ve-
hicle, in particular, around the wheels
or wheel housings.
The tires are not equipped with an air
pressure sensor.
Snow tires or tire chains are used.
Non −genuine Toyota wheels are used.
CAUTION
The use of nongenuine wheels will
cause the air pressure sensors to
transmit the electronic code in dif-
ferent manner, resulting in the sys-
tem failure.
The use of different type of tires
with genuine wheels may also
cause the malfunction of the sys-
tem.

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
appropriate pressure: The antilock
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 and the brake assist
system work properly, the light turns off
after a few seconds. Thereafter, if either
of the systems malfunctions, the light
comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
following systems do not operate, but the
brake system still operates conventionally.
