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 (4WD mode) or rear wheels
(2WD mode). At this time, the slip indi-
cator 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.
“VSC TRAC” warning light
This light warns that there is a problem
somewhere in the active traction control
system or the vehicle stability control sys-
tem.
The warning light will come on when the
ignition key is turned to “ON” and will go
off after a few seconds.

The brake pad or actuator temperature
increases during continuous operation of
the active traction control system or ve-
hicle stability control system such as on
slippery roads. If the brake pad or actua-
tor temperature becomes too high while
the active traction control system or ve-
hicle stability control system is operating,
a buzzer will start to sound intermittently
to indicate that the active traction 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 the time, the “VSC TRAC” warning light
will come on and the active traction con-
trol system temporarily stops operating in
order to protect the brake pad. (Although
the active traction control system does not
operate, there is no problem to continue
your driving.) The system will be automati-
cally restored after a short time and the
warning light goes out.
If the light comes on while driving, the
active traction control system does not
work. However, as conventional braking
operates when applied, there is no prob-
lem 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.
The “VSC OFF” indicator light will come
on when the “VSC TRAC” warning light
comes on even if the center differential
lock switch is not pushed. The vehicle stability control system
helps provide integrated control of the
systems such as antilock brake sys-
tem, traction control, engine control,
etc. This system automatically controls
the brakes and engine to help prevent
the vehicle from skidding when corner-
ing on a slippery road surface or oper-
ating steering wheel abruptly.
This vehicle stability control activates
when the vehicle speed is more than the
following speed.
Tw o
−wheel drive models:
15 km/h (9 mph)
Four −wheel drive models:
“2WD” or “4HI” mode 15 km/h (9 mph)
“4LO” mode 30 km/h (18 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 vehicle stability control sys-
tem is operating, you must always
drive carefully and attentively to
avoid serious injury. Reckless driv-
ing will result in an unexpected ac-
cident. If the slip indicator light
blinks, sounding an alarm sounds,
special 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 434 in Section 72.)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.
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.Fourwheel drive models only—

1: Height control mode select switch
2: Height control switch
This rear height control air suspension
controls the vehicle height depending
on vehicle driving conditions.
You can choose automatic control mode
or manual control mode. In automatic
control mode, you can select the ve-
hicle height between “HI” (high), “N”
(normal) and “LO” (low) modes with the
height control switch. In manual control
mode, you can adjust the vehicle height
seamlessly with the height control
switch.
To change the mode between automatic
control mode and manual control mode,
use the height control mode select switch.The vehicle height is automatically ad-
justed to a selected height mode. Howev-
er, when the front drive control is in “4LO”
mode, the vehicle height cannot be ad-
justed automatically even if the vehicle
condition changes, but height mode can
be changed manually with the height con-
trol switch.
(a) Vehicle height modes
“N” (normal) mode—
The vehicle height in this mode is stan-
dard. Regardless of the number of occu-
pants or the luggage loading condition, the
vehicle height is always automatically ad-
justed to a fixed height in this mode while
the engine is running.
This mode is suitable for ordinary driving.
“HI” (high) mode—
The vehicle height is about 40 mm (1.6
in.) higher at rear than “N” mode height.
This mode is suitable when driving on
bumpy roads and through water.
However, when the vehicle speed exceeds
30 km/h (18 mph) in “HI” mode, “N” mode
is automatically selected.
CAUTION
“HI” mode should be only used for
severe offroad driving conditions.
Because the vehicle’s center of gravi-
ty is higher in this setting, the ve-
hicle may become unstable when
turning abruptly, resulting in an acci-
dent.

NOTICE
If the vehicle height is changed fre-
quently when the vehicle is heavily
loaded, the compressor may over-
heat, causing the vehicle height ad-
justment operation to stop.
 Before you lower the vehicle height
with the height control switch,
check under the vehicle to make
sure nothing to damage the vehicle
or no one to be injured is there and
that the underbody of the vehicle
does not touch the ground.
 After unloading, the height of a ve-
hicle equipped with the rear height
control air suspension becomes
slightly higher than the normal ve-
hicle height. Take sufficient care
where the overhead height is re-
stricted.
 Do not select “LO” mode for bumpy
roads. If the underbody of the ve-
hicle touches the road surface, the
vehicle may be damaged.
If you attempt to adjust the vehicle height
with anything such as snow, ice, or stones
in contact with the vehicle body, the ve-
hicle height may not change. In this case,
stop the vehicle, press the height control
mode select switch, and check that manu-
al control mode indicator light comes on.
Then, remove the obstruction.
CAUTION
If you drive through water, set the
vehicle height to “HI” with the height
control switch and then change to
manual control mode by pushing the
height control mode select switch. Do
not exceed 30 km/h (18 mph) or “HI”
mode will automatically change to
“N” mode. Do not drive through water
deeper than about 700 mm (28 in.)
even if the vehicle height is in “HI”
mode.
NOTICE
When jacking up or insta lling tire
chains, be sure to set manual con-
trol mode by pushing the height
control mode select switch and stop
the engine. Otherwise, the vehicle
height may change because of the
