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.(h) “VSC TRAC” Warning Light
The light warns that there is a problem
somewhere in the following.
Traction control system
“AUTO LSD” system
Vehicle stability 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.
There is no problem when the “VSC
TRAC” warning light comes on when the
brake actuator temperature becomes high.
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.
(i) 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 pretensioners
are operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, front seat belt pretensioner assem-
blies, inflators, warning light, interconnect-
ing wiring and power sources.

Make sure the “AUTO LSD” indicator light
comes on under the above condition when
you use the “AUTO LSD” system.
The slip indicator light blinks when the
system is controlling the spinning of the
rear wheels.
The “AUTO LSD” and slip indicator lights
come on for a few seconds when the
ignition key is turned to “ON”. If the indi-
cator lights does not come on when the
ignition key is turned to “ON”, contact
your Toyota dealer.“VSC TRAC” warning light
This light warns that there is a problem
somewhere in the following.
“AUTO LSD” system
Traction control system
Vehicle stability control system
When the system is normal and the igni-
tion key is turned to “ON”, the warning
light will come 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 “ON”. Depressing the brake pedal repeatedly
may turn on the light. It is normal if it
goes out after a few seconds.
The brake actuator temperature increases
during continuous operation of the above
mentioned systems such as on slippery
roads. If the brake actuator temperature
becomes too high while any of the sys-
tems is operating, a buzzer will start to
sound intermittently to indicate that the
“AUTO LSD” system can no longer oper-
ate. In this case, immediately stop your
vehicle at a safe place.
If the system continues to operate, the
buzzer sound changes from intermittent to
continuous. (The continuous buzzer
sounds for about 3 seconds.)
At the time the “VSC TRAC” warning light
will come on and the “AUTO LSD” system
temporarily stops operating in order to
protect the brake actuator. (Although the
“AUTO LSD” system does not operate, it
is no problem to continue driving.) The
system will be automatically restored after
a short time and the “VSC TRAC” warning
light goes off.

Exhaust system
If you notice any change in the sound of
the exhaust or smell exhaust fumes, have
the cause located and corrected immedi-
ately. (See “Engine exhaust cautions” in
Section 2.)
INSIDE THE VEHICLE
Items listed below should be checked
regularly, e.g. while performing periodic
services, cleaning the vehicle, etc.
Lights
Make sure the headlights, stop lights, tail
lights, turn signal lights, and other lights
are all working. Check headlight aim.
Service reminder indicators and warning
buzzers
Check that all service reminder indicators
and warning buzzers function properly.
Steering wheel
Be alert for changes in steering condition,
such as hard steering or strange noise.Seats
Check that all seat controls such as seat
adjusters, seatback recliner, etc. operate
smoothly and that all latches lock securely
in any position. Check that the head re-
straints move up and down smoothly and
that the locks hold securely in any latched
position. For folding
−down seatback
(bench seat) and rear seatback (rear split
bench seat), check that the latches lock
securely.
Seat belts
Check that the seat belt system such as
buckles, retractors and anchors operate
properly and smoothly. Make sure the belt
webbing is not cut, frayed, worn or dam-
aged.
Accelerator pedal
Check the pedal for smooth operation and
uneven pedal effort or catching.
Clutch pedal
Check the pedal for smooth operation.
Brake pedal
Check the pedal for smooth operation and
that the pedal has the proper clearance.
Check the brake booster function. Brakes
At a safe place, check that the brakes do
not pull to one side when applied.
Parking brake
Check that the lever has the proper travel
and that, on a safe incline, your vehicle
is held securely with only the parking
brake applied.
Automatic transmission “Park” mecha-
nism
Check the lock release button of the se-
lector lever (floor shift type) for proper
and smooth operation. On a safe incline,
check that your vehicle is held securely
with the selector lever in “P” position and
all brakes released.
OUTSIDE THE VEHICLE
Items listed below should be performed
from time to time, unless otherwise
specified.
