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.

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.

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

(e) Parking and stopping tips
If you immediately stop the engine to park
the vehicle after off−road driving, the ve-
hicle height is lowered slightly as the ve-
hicle becomes cool. When parking, make
sure there is nothing that will be in con-
tact with the underbody of the vehicle.
When you start the engine, the vehicle
returns to the previous height.
If you park the vehicle for a long time,
the vehicle height may be gradually low-
ered. When parking for a long time, make
sure there is nothing that will be in con-
tact with the underbody of the vehicle.
When you start the engine, the vehicle
returns to the previous height.
If you stop the engine, the vehicle height
may change in accordance with the
change in the temperature. When you
start the engine, the vehicle returns to the
previous height. (f) Rear height control failure warning
If there is a problem somewhere in the
rear height control air suspension, “N”
mode is automatically selected. If this oc-
curs, the manual control mode indicator

tion other than “P” or “N” while the vehicle
is stopped, you may hear a sound caused
by the expansion and contraction of the
propeller shaft. This does not indicate a
malfunction.
CAUTION
The higher vehicle height should be
only set for severe offroad driving
conditions. Because the vehicle’s cen-
ter of gravity is higher in this setting,
the vehicle may become unstable
when turning abruptly, resulting in an
accident.
NOTICE

hicle must be stopped. Otherwise,
when the vehicle speed exceeds 30
km/h (18 mph), automatic control
mode is activated and “N” is se-
lected automatically. Proper caution
should be taken in places where the
overhead height is limited.
 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.
