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 is used only when wheel
spinning occurs in a ditch or on a
rough surface.
This system is effective in case one of
the rear wheels is spinning.
NOTICE
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.
CY16075
To turn on the system, briefly push the
VSC OFF" switch. At this time, the
AUTO LSD" indicator and slip indica-
tor lights will come on.
To turn off the system, briefly push the
VSC OFF" switch again and the AUTO
LSD" and slip indicator lights will go off.
If the engine is turned off while the
AUTO LSD" and slip indicator lights are
on and then restarted, the indicator lights
will turn off automatically.

the engine switch is turned to ON", con-
tact your Toyota dealer.The brake actuator temperature increases
during continuous operation of the AUTO
LSD" system, the traction control system
and the vehicle stability control system
such as on slippery roads. If the brake
actuator temperature becomes too high
while any of the systems is operating, a
buzzer will start to sound intermittently to
indicate that the AUTO LSD" system can
no longer operate. In this case, immedi-
ately 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 AUTO LSD" system
temporarily stops operating in order to

The vehicle stability control system
helps provide integrated control of the
systems such as anti−lock brake sys-
tem, traction control, engine control,
etc. This system automatically controls
the output of the brakes or engine to
help prevent the vehicle from skidding
when cornering on a slippery road sur-
face or operating steering wheel abrupt-
ly.
The vehicle stability control system is acti-
vated when the vehicle speed is more
than 15 km/h (9 mph).
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 sys-
tem is in the self−check mode, but does
not indicate a malfunction.CAUTION
Do not rely excessively on the ve-
hicle stability control system. Even
if the system is operating, it cannot
completely eliminate the possibility
of an accident. Always keep safe
driving in mind, as reckless driving
increases the risk of an accident. If
the slip indicator light blinks, spe-
cial 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 443 in Section 7−2.)
CY16073
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.
If the brake pedal is depressed while the
vehicle stability control system is active,
the brake pedal will become hard at an
earlier position than usual. However, the
brakes will respond to the pedal force if
depressed further.
The slip indicator light comes on for a few
seconds when the engine switch is turned
to ON". If the indicator light does not
come on when the engine switch is turned
on, contact your Toyota dealer.

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 four−wheel drive control
switch knob (full−time four−wheel drive
models) or multi−mode control switch
knob (multi−mode four−wheel drive
models) 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 SYSTEM1. Full−time four−wheel drive models Turn the four−wheel drive control
switch knob to the L4" position.
The system will not operate if the four−
wheel drive control switch knob is in the
H4" position. Multi−mode four−wheel drive mod-
elsTurn the multi−mode control
switch knob to the L4" position.
The system will not operate if the multi−
mode control switch knob is in the H4"
position. 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.

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 gradually. 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 engine switch is
turned to ON". If any of the indicator
lights does not come on when the engine
switch is turned on, contact your Toyota
dealer.
The brake actuator temperature increases
during continuous operation of the h
ill−
start assist control system, the active
traction control system and the vehicle
stability control system. If the brake ac-
tuator temperature becomes too high while
any of the systems is operating, a buzzer
will start to sound intermittently 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.)

188
At this time, the slip indicator light will
come on, the downhill assist control sys-
tem indicator light flash and the downhill
assist control system stops operating tem-
porarily in order to protect the brake ac-
tuator. (Although the downhill assist con-
trol system does not operate, it is no
problem to continue your driving.) The
system will be automatically restored after
a short time and the slip indicator light
and the downhill assist control system in-
dicator light go out.
