(h) Engine Oil Replacement Reminder
Light (for vehicles sold in U.S.A.)
This light acts as a reminder to replace
the engine oil.
This light will come on when the ignition
key is turned to “ON” and will go off after
about a few seconds.
When you drive for about 7200 km (4500
miles) after the engine oil replacement,
this light illuminates for about 3 seconds
and then flashes for about 12 seconds
with the ignition key turned to the “ON”
position. If you continue driving without
the engine oil replacement, and if the driv-
ing range exceeds 8000 km (5000 miles),
the light will come on after the ignition
key is turned to the “ON” position. The
light will remain on thereafter.
If the light is flashing, we recommend that
you replace the engine oil at an early
opportunity depending on the driving and
road condition. If the light comes on, re-
place it as soon as possible. You need to reset the light after the en-
gine oil replacement. Reset the light by
following the procedure below:
1. Turn the ignition key to the “ACC” or “LOCK” position with the odometer
reading shown. (For details, see
“Odometer and two trip meters” on
page 146 in this Section.)
2. Turn the ignition key to the “ON” posi- tion while holding down the trip meter
reset button.
Hold down the button until the light goes
off. Before the light goes off, it illuminates
for 3 seconds, flashes for 2 seconds and
illuminates for 1 second.
If the system fails to reset, the light will
remain flashing.
(i) “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.
Anti
−lock brake system
Brake assist system
Traction control system
(two −wheel drive models)
Active traction control system
(four −wheel drive models)
“AUTO LSD” system
(two −wheel drive models)
Vehicle stability control system
Downhill assist control system
(four −wheel drive models)
Hill −start assist control system
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti −lock brake system does not operate,
so that the wheels will lock up during a
sudden braking or braking on slippery
road surfaces.

If either of the following conditions oc-
curs, this indicates a malfunction some-
where in the components 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 while you are dri-
ving.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Toyota dealer.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
Either of the following conditions may
occur, but do not indicate a malfunc-
tion:
The light may stay on for about 60
seconds after the ignition key is turned
to the “ON” position. It is normal if it
turns off after a while.
Depressing the brake pedal repeatedly
may turn on the light. It is normal if it
turns off after a few seconds.
(j) “VSC TRAC” Warning Light
The light warns that there is a problem
somewhere in the following.
Vehicle stability control system
Traction control system
(two −wheel drive models)
Active traction control system
(four− wheel drive models)
“AUTO LSD” system
(two−wheel drive models)
Downhill assist control system
(four− wheel drive models)
Hill−start assist control system
The light will come on when the ignition
key turned to “ON”, and will go off after
a few seconds. It is not a malfunction that the warning
light may stay on for 60 seconds after the
ignition key is turned to the “ON” position.
Depressing the brake pedal repeatedly
may turn on the lights. It is normal if they
go out after a few seconds.
If the light comes on while driving, the
above mentioned systems do not work.
However, as conventional braking operates
when applied, there is no problem to con-
tinue your driving.
In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the ignition key is turned to “ON”.
The warning light remains on after the
ignition key is turned to “ON”.
The warning light comes on while driv-
ing.
When the brake fluid level is too low, the
above mentioned systems will not operate
and the warning light comes on.
(k) Open Door Warning Light
This light remains on until all the side
doors and back door are completely
closed.

155
(l) SRS Warning Light
This indicator comes on when the igni-
tion key is turned to the “ON” position.
It goes off after about 6 seconds. This
means the SRS airbags and seat belt
pretensioners 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 passenger occupant
classification system and indicator light,
front passenger ’s seat belt buckle switch,
seat belt pretensioner assemblies, inflat-
ors, “RSCA OFF” indicator light, intercon-
necting wiring and power sources.
If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Toyota dealer as soon as possible.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion or remains on for more than 6
seconds or flashes.
The light comes on or starts flashing
while driving. The SRS warning light will come on and
front passenger occupant classification in-
dicator light will indicate “OFF” if there is
a malfunction in the front passenger occu-
pant classification system.
(m) Automatic Transmission Fluid
Temperature Warning Light
(fourwheel drive models)
This light warns that the automatic trans-
mission fluid temperature is too high.
If this light comes on while you are driv-
ing, slow down and pull off the road. Stop
the vehicle at a safe place and put the
selector lever in “P”. With the engine id-
ling, wait until the light goes off. If the
light goes off, you may start the vehicle
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 425 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 190 in Section 1 −7.

(o) Low Windshield Washer Fluid Level
Warning Light (for vehicles sold in
Canada)
The light warns that the windshield washer
fluid level is too low. Add washer fluid at
your earliest opportunity. (For instructions,
see “Adding washer fluid” on page 437 in
Section 7 −3.)
(p) 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. CHECKING SERVICE REMINDER
INDICATORS (except the low fuel level
warning light and low windshield
washer fluid level warning light)
