When getting the vehicle out of mud or
newly fallen snow, etc., turn off the
vehicle stability control system. This
system that controls engine perfor-
mance interferes with the process of
freeing rear wheels (two wheel drive
models) or 4 wheels (four wheel drive
models).
To turn off: First, push the “VSC OFF”
switch to turn off the traction control
system and check that the “AUTO LSD”
and slip indicator lights come on. Then,
push and hold the “VSC OFF” switch
for 3 seconds or more with the vehicle
stopped.
The “VSC OFF” and slip indicator lights
will come on.To turn on: Briefly push the “VSC OFF”
switch once again.
The “VSC OFF” and slip indicator lights
will go off.
If the engine is turned off while the “VSC
OFF” and slip indicator lights are on and
then restarted, the indicator lights will turn
off automatically.
When you briefly push the “VSC OFF”
switch, turn off the vehicle stability control
system. See “Traction control system” on
page 184 in this Section.
The “VSC OFF” and slip indicator lights
come on for a few seconds when the
ignition key is turned to “ON”. If the indi-
cator lights do not come on when the
ignition key is turned to “ON”, contact
your Toyota dealer.
CAUTION
Do not drive with the vehicle stability
control system continuously turned
off.

The light may come on for 60 seconds
after the ignition key is turned to “ON”. It
is normal if they go out after a while.
Depressing the brake pedal repeatedly
may turn on the light. It is normal if they
go out after a few seconds.
If the light flashes while driving, the ve-
hicle stability control system does not
work. However, if the brakes operate nor-
mally 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 flashes while driving.The downhill assist control system is a
system that assists the deceleration of
the engine brake when you drive down
a steep hill. When you are driving down
a hill with the front drive control switch
knob in the “L4” position, push the
“DAC” switch to limit the vehicle’s ac-
celeration. If the vehicle is traveling at
a speed of 25 km/h (15 mph) or less,
you can descend at a constant speed.
CAUTION
Do not rely excessively on the down-
hill assist control system. It may not
be able to maintain a low speed over
road surfaces or off road surfaces on
which sliding can easily occur, such
as extremely steep slopes or icy or
muddy roads.
TO ACTIVATE THE DOWNHILL ASSIST
CONTROL SYSTEM
1. Turn the front drive control switch knob to the “L4” position.
The system does not operate when the
front drive control switch knob is in the
“H2” or “H4” position, or the rear differen-
tial is locked.
2. In order to make full use of the en- gine brake, putting the transmission
in “L” or “2” is recommended.
The system will operate even if the trans-
mission selector lever is in “D”, “4”, “3”
or “N”. However, when it is in “L” or “2”
the engine brake can also be utilized en-
abling the system to operate more effec-
tively.

3. Push the “DAC” switch to turn thesystem on. The downhill assist con-
trol system indicator light on the in-
strument panel will come on.
If the downhill assist control system indi-
cator light flashes, one of the following
may be the cause:
The selector lever is in the “N” posi-
tion.
The front drive control switch knob is
in the “H2” or “H4” position.
The rear differential is locked.
If the indicator light does not come on
when the switch is pushed, contact your
Toyota dealer.

With the vehicle traveling at a speed of
25 km/h (15 mph) or less, release your
foot from the accelerator or brake pedal
to activate the system. The vehicle will
descend the hill at a low speed. While the
system is operating, the slip indicator light
on the instrument panel will flash and the
stop lights and high mounted stoplight will
be lit.
If you push the “DAC” switch to turn the
system off while it is in operation, the
system will stop operating gr adually. The
downhill assist control system indicator
light will flash to alert the driver. To con-
tinue driving at a low speed, push the
“DAC” switch to turn the system on. The slip indicator light and downhill assist
control system indicator light come on for
a few seconds when the ignition key is
turned to “ON”. If any of the indicator
lights does not come on when the ignition
is turned on, contact your Toyota dealer.
If the system is used frequently, the
brake actuator temperature may become
too high and a buzzer will sound inter-
mittently.
If this happens, the downhill assist control
system indicator light will flash and a
buzzer will sound intermittently. When the
temperature of the brake actuator de-
creases, the system will begin to operate
again. Until it restarts, the traction control
system and hill
−start assist control system
will not operate; however, the conventional
brake can be operated.
The brake actuator temperature increases
during continuous operation of the follow-
ing systems under conditions such as on
slippery roads.

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 downhill assist
control system can no longer operate. In
this case, stop your vehicle immediately 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 this time, the slip indicator light will
come on and the downhill assist control
system stops operating temporarily in or-
der to protect the brake actuator. (Al-
though the downhill assist control system
does not operate, it is no problem to con-
tinue your driving.) The system will be
automatically restored after a short time
and the slip indicator light goes out.
LS17010
If there is any abnormality in the sys-
tem, the “VSC OFF” warning light will
flash. When the “DAC” switch is
pushed, the downhill assist control sys-
tem indicator light also flash.
If the “VSC OFF” warning light flashes,
there may be an abnormality in any of the
following system in addition to the down-
hill assist control system.
Hill−start assist control system
Traction control system
Vehicle stability control system
Downhill assist control system “VSC OFF” warning light
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 the “ON” position.
Depressing the brake pedal repeatedly
may turn on the light. It is normal if it
goes out after a few seconds.
If the warning light flashes while driving,
the system does not work. However, if 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 flashes while driving.
