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,

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 normal driving on wet, icy or
snow −covered roads. This position pro-
vides greater traction than two− wheel
drive.
With the vehicle stability control
system—In this m ode, the vehicle stability
control system is off. (See “Vehicle
stability control system” on page 177 in
this Section)
“L4” (low speed position, fourwheel
drive): Front drive control switch knob at
“L4”
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 mode, the vehicle stability
control system is off. (See “Vehicle
stability control system” on page 177 in
this Section.)
Fourwheel drive system
(a) Front drive control

1732005 TACOMA from Mar. ’05 Prod. (OM35862U)
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.
LS17007
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. 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.

1742005 TACOMA from Mar. ’05 Prod. (OM35862U)
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-
ing.
