(a) Brake System Warning Light
This light comes on in the following cases
when the ignition key is in the “ON” posi-
tion.
When the parking brake is applied...
This light comes on for a few seconds
when the ignition key 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 igni-
tion key is in the “ON” position.
The light does not come on even if the
ignition key is turned on with the park-
ing 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 ignition key 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.
(c) Passenger ’s Seat Belt Reminder
Light
The light acts as a reminder to have the
passenger buckle up the seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light flashes if a
passenger sits in the passenger seat and
does not fasten the seat belt. Unless the
passenger fastens the belt, the light stays
flashing. However, if a 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
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.

(k) 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

erating properly.
This warning light system monitors the
airbag 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 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 for more than 6

in your power steering system.
If the light comes on while you are driv-
ing, have your vehicle checked by your
Toyota dealer as soon as possible.(m) Key Reminder Buzzer
This buzzer acts as a reminder to remove
the key when you open the driver’s door
with the ignition key in the “ACC” or
“LOCK” position.
(n) Light reminder buzzer
The buzzer will sound if the headlight
switch is left on and the driver’s door is
opened with the key removed from the
ignition switch.
(o) Warning function of the Sequential
Manual Transmission (sequential
manual transmission only)
When driving, if any incorrect operation
that may cause damage to this system is
performed or if the gear is not shifted as
desired by the driver, the warning buzzer
will sound and the gear position indicator

If tire grip performance exceeds its
capability, or if hydroplaning occurs
during high speed driving in the rain,
the antilock brake system does not
provide vehicle control.
Antilock brake system is not de-
signed to shorten the stopping dis-
tance: Always drive at a moderate
speed and maintain a safe distance
from the vehicle in front of you.
Compared with vehicles without an
antilock brake system, your vehicle
may require a longer stopping dis-
tance 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
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.
SD02002a
“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 turns off after a few seconds. There-
after, if the system malfunctions, the light
comes on again.
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.
