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.

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.

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.

NOTICE
Do not use any gears other than
first gear when starting off and
moving forward. Doing so may dam-
age the clutch.
 Make sure the vehicle is completely
stopped before shifting into reverse.
LS17006
Use the front drive control switch knob
to select the following transfer modes.
“H2” (high speed position, twowheel
drive): Front drive control switch knob at
“H2”
Use this for normal driving on dry hard −
surfaced roads. This position gives greater
economy, quietest ride, least wear and
better vehicle control.
“H4” (high speed position, fourwheel
drive): Front drive control switch knob at
“H4”
The four −wheel drive indicator light comes
on when the “H4” mode is selected.
Use this for greater traction than two −
wheel drive. (When you experience a loss
of power, such as wheel spinning.) This
position provides greater traction than
two −wheel drive.
With the vehicle stability control
system—In this mode, the vehicle stability
control system is off. (See “Vehicle
stability control system” on page 189 in
this Section)
“L4” (low speed position, fourwheel
drive): Front drive control switch knob at
“L4”
Fourwheel drive system
(a) Front drive control

1812007 TACOMA from Sep. ’06 Prod. (OM35877U)
The four−wheel drive and “4LO” (low
speed four −wheel drive) indicator lights
come on when the “L4” mode is selected.
Use this for maximum power and traction.
Use “L4” position for climbing or descend-
ing steep hills, off −road driving, and hard
pulling in sand, mud or deep snow.
See “(c) Shifting procedure” for further in-
structions.
With the vehicle stability control
system—In this m ode, the vehicle stability
control system is off. (See “Vehicle
stability control system” on page 189 in
this Section.) 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.
(b) A.D.D. (automatic
disconnecting differential) (c) Shifting procedure (with
manual transmission)

1842007 TACOMA from Sep. ’06 Prod. (OM35877U)
If the “4LO” (low speed four−wheel drive)
indicator light continues to blink when you
operate the front drive control switch knob
to the “H4” or “L4” position, drive forward
or backward in a short distance, then stop
the vehicle completely, shift the automatic
transmission selector lever securely into
“N” and operate the switch knob again.
If the indicator 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.
The traction control system automatical-
ly helps prevent the spinning of rear
wheels (twowheel drive models) or 4
wheels (fourwheel drive models) when
the vehicle is started or accelerated on
slippery road surfaces.
When the ignition key is turned to “ON”,
the system automatically turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power to the rear wheels (twowheel
drive models) or 4 wheels (fourwheel
drive models) cannot be maintained,
even though the traction control sys-
tem is in operation. Do not drive the
vehicle under any speed or maneuver-
ing conditions which may cause the
vehicle to lose traction control. In si-
tuations where the road surface is
covered with ice or snow, your ve-
hicle should be fitted with snow tires
or tire chains. Always drive at an ap-
propriate and cautious speed for the
present road conditions.
LS17007b
NORMAL MODE
Leave the system on during the ordi-
nary driving so that it can operate
when needed.
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
begins to move. This means that the trac-
tion control system is in the self −check
mode, but does not indicate a malfunction.
Traction control system

1852007 TACOMA from Sep. ’06 Prod. (OM35877U)
When the traction control system is oper-
ating, the following conditions occur:
The system controls the spinning of the
rear wheels (two−wheel drive models)
or 4 wheels (four −wheel drive models).
At this time, the slip indicator light
blinks.
You may feel vibration or noise in your
vehicle, caused by operation of the
brakes. This indicates the system is
functioning properly.
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.
The brake actuator temperature increases
during continuous operation of the follow-
ing systems under conditions such as on
slippery roads.
Traction control system
“AUTO LSD” system
Downhill assist control system
Hill −start assist control system 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 l
onger 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.

LS17011
The “AUTO LSD” system aids traction
by using the traction control system to
control engine performance and braking
when one of the rear wheels begins to
spin.
This system should be used only when
wheel spinning occurs in a ditch or
rough surface.
This system is effective in case one of
the rear wheels is spinning.
CAUTION
Do not use the “AUTO LSD” system
in conditions other than the above. A
much greater steering effort and more
careful cornering control will be re-
quired.
