The active traction control system auto-
matically helps prevent the spinning of
4 wheels when the vehicle is started or
accelerated on slippery road surfaces.
When the engine switch 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 4 wheels cannot be
maintained, even though the traction
control system is in operation. Do not
drive the vehicle under any speed or
maneuvering conditions which may
cause the vehicle to lose traction
control. In situations where the road
surface is covered with ice or snow,
your vehicle should be fitted with
snow tires or tire chains. Always
drive at an appropriate and cautious
speed for the present road condi-
tions.

NORMAL DRIVING 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 ac-
tive traction control system is in the self−
check mode, but does not indicate a mal-
function.
When the active traction control system is
operating, the following conditions occur:
The system controls the spinning of the
4 wheels. At this time, the slip indica-
tor 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 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 brake actuator temperature increases
during continuous operation of the active
traction control system, the vehicle stabil-
ity control system, the downhill assist con-
trol system and the hill−start assist control
system such as on sli ppery roads. If the
brake actuator temperature becomes too
high while any of the systems is operat-
ing, a buzzer will start to sound intermit-
tently to indicate that the active 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.)

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.
