The light comes on while you are driv-
ing.
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.
With rear differential lock: However, it is
a normal operation for the light to be on
with rear differential locked. At this time,
the anti −lock brake system does not oper-
ate. With the vehicle stability control sys-
tem—
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
“AUTO LSD” system
Vehicle stability control system
Downhill assist control system
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.

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.
Any of the following conditions may oc-
cur, but do not indicate a malfunction:
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.
With rear differential lock: The light
comes on with rear differential locked.
At this time, the anti−lock brake sys-
tem, the brake assist system, the ve-
hicle stability control system, the trac-
tion control system, the downhill assist
control system and the hill −start assist
control system do not operate.

The A.D.D. can be engaged or disen-
gaged by the shifting operations de-
scribed in “(c) Shifting procedure”.
You should drive in four−wheel drive for
at least 16 km (10 miles) each month.
This will assure that the front drive com-
ponents are lubricated. SHIFTING BETWEEN “H2” AND “H4”
To shift from “H2” to “H4”,
reduce the
vehicle speed to less than 100 km/h (62
mph) and turn the front drive control
switch knob fully clockwise.
If the four −wheel drive indicator light con-
tinues to blink when you operate the front
drive control switch knob from the “H2” to
the “H4” position, this reminds you that
the transfer mode is not securely in “H4”
mode. Drive straight ahead while acceler-
ating or decelerating.
If the four −wheel drive indicator light con-
tinues to blink and the buzzer sounds
when you operate the front drive control
switch knob from the “H2” to the “H4”
position, this reminds you that the transfer
mode is not in “H4” mode. Stop the ve-
hicle or reduce the vehicle speed to less
than 100 km/h (62 mph). Operate the
switch knob again.
CAUTION
Never operate the front drive control
switch knob if the wheels are slip-
ping. Stop the slipping or spinning
before operating.
To shift from “H4” to “H2”, turn the
front drive control switch knob fully coun-
terclockwise.
This can be done at any speed. You need
not depress the clutch pedal.
If the four −wheel drive indicator light con-
tinues to blink when you operate the front
drive control switch knob from the “H4” to
the “H2” position, this reminds you that
the transfer mode is not securely in “H2”
mode. Drive straight ahead while acceler-
ating or decelerating, or drive forward or
backward in a short distance.
If the indicator light continues to blink
even if doing so, contact your Toyota
dealer as soon as possible. There may be
a trouble in the four −wheel drive system.
CAUTION
Never operate the front drive control
switch knob if the wheels are slip-
ping. Stop the slipping or spinning
before operating.

If the brake actuator temperature becomes
too high while any of the systems is oper-
ating, a buzzer will start to sound intermit-
tently to indicate that the traction control
system can no longer operate. 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 slip indicator light will
come on and the traction control system
temporarily stops operating in order to
protect the brake actuator. (Although the
traction control system does not operate,
it is no problem to continue driving.) The
system will be automatically restored after
a short time and the slip indicator light
goes off.
With rear differential lock: However, it is
a normal operation for the light to be on
with rear differential locked. At this time,
the traction control system does not oper-
ate.

“VSC TRAC” warning light
This light warns that there is a problem
somewhere in the following.
Traction control system
Vehicle stability control system
“AUTO LSD” system
Downhill assist control system
Hill− start assist control system When the system is normal and the igni-
tion key is turned to “ON”, the light will
come on and will go off after a few sec-
onds.
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 lights. It is normal if it
goes out after a few seconds.
If the “VSC TRAC” warning light and slip
indicator light come on while driving, the
traction control system does not work.
However, as the brakes operate normally
when applied, it is no problem to continue
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-

1782005 TACOMA from Mar. ’05 Prod. (OM35862U)
CAUTION
Do not rely excessively on the ve-
hicle stability control system. Even
if the vehicle stability control sys-
tem is operating, you must always
drive carefully and attentively to
avoid serious injury. Reckless driv-
ing will result in an unexpected ac-
cident. If the slip indicator light
blinks and an alarm sounds, special
care should be taken while driving.
Only use tires of specified size. The
size, manufacturer, brand and tread
pattern for all 4 tires should be the
same. If you use the tires other
than specified, or different type or
size, the vehicle stability control
system may not function correctly.
When replacing the tires or wheels,
contact your Toyota dealer. (See
“Checking and replacing tires” on
page 353 in Section 72.)
LS17007
If the vehicle is going to skid during driv-
ing, the slip indicator light blinks and an
alarm sounds intermittently. Special care
should be taken while driving.
The slip indicator light comes on for a few
seconds when the ignition key is turned
to “ON”. If the indicator light does not
come on when the ignition is turned on,
contact your Toyota dealer.
