The vehicle stability control system
helps provide comprehensive control of
the systems such as anti- lock brake
system, 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 system activates when the vehicle
speed is about 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, manufacture, 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 tiresº on
page 388 in Section 7- 2.)
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 ONº. If the indicator light does not
come on when the ignition is turned on,
contact your Toyota dealer.

VSC and Tire Pressure Warning System
1. ABS Operation
If the brake pedal is depressed suddenly, the ABS controls the hydraulic pressure of the wheel cylinders for all the four
wheels to automatically avoid wheel locking and ensure the directional and steering stability of the vehicle. If the brake pedal
is depressed suddenly, the skid control ECU with actuator controls the solenoids in the actuators using the signals from the
sensors to move the brake fluid to the reservoir in order to release the braking pressure applied to the wheel cylinder. If the
skid control ECU with actuator detects that the fluid pressure in the wheel cylinder is insufficient, the ECU controls the
solenoids in the actuators to increase the braking pressure.
2. Traction Control Operation
The traction control system controls the engine torque, the hydraulic pressure of the driving wheel cylinders, slipping of the
wheels which may occur at start or acceleration of the vehicle, to ensure an optimal driving power and vehicle stability
corresponding to the road conditions.
3. VSC Operation
Unexpected road conditions, vehicle speed, emergency situation, and any other external factors may cause large under- or
over-steering of the vehicle. If this occurs, the VSC system automatically controls the engine power and wheel brakes to
reduce the under- or over-steering.
To reduce large over-steering :
If the VSC system determines that the over-steering is large, it activates the brakes for the outer front turning wheels
depending on the degree of the over-steering to produce the moment toward the outside of the vehicle and reduce the
over-steering.
To reduce large under-steering :
If the VSC system determines that the under-steering is large, it controls the engine power and activates the rear wheel
brakes to reduce the under-steering.
VSC indicator light
If an mulfunction occurs in the VSC system, the VSC indicator lights up to warn the driver.
4. Mutual System Control
To efficiently operate the VSC system at its optimal level, the VSC system and other control systems are mutually controlled
while the VSC system is being operated.
Engine control
The engine power does not interfere with the VSC brake control by fuel cut controlling and reducing the engine output.
Engine control and electronically controlled transmission control
The strong braking force does not interfere with the braking force control of the VSC system by turning off the accel and
reducing changes in the driving torque at shift-down.
VSC system operation indication
The slip indicator light flashes and the buzzer alarm intermittently to warn the driver that the current road is slippery, while the
VSC system is being operated.
5. Fail Safe Function
If an mulfunction occurs in the skid control ECU with actuator, sensor signals, and/or actuators, the skid control ECU with
actuator inhibits the brake actuator control and inputs the mulfunction signal to the engine control module. According to the
mulfunction signal, the brake actuator turns off the solenoid and the engine control module rejects any electronically
controlled request from the VSC system. As a result, the vehicle functions without the ABS, BA, TRAC, and VSC systems.

1. Seat Belt Warning System
When the ignition SW is turned to the ON position, the signal is input to the body ECU. At this time, to judge whether or not
the driver fastens the seat belt, the signal from the buckle SW LH is input to TERMINAL (A) 10 of the body ECU via multiplex
commnunication system (Bean bus). If the driver does not fasten the seat belt, the seat belt warning light in the combination
meter flashes and the alarm buzzer goes on, in response to the communication control of the body ECU etc.
Additionally, the sensor (Inside of buckle SW (Front passenger's side) ) installed on the front passenger seat detects the
passenger and determines whether or not the passenger fastens the seat belt.
If the passenger does not fasten the seat belt, the front passenger seat belt warning light is flashed.
2. Key Reminder System
If the driver door is opened with the ignition SW set at the ACC or OFF position and the ignition key remained inserted into
the key cylinder (The unlock warning SW is on), the signal from the unlock warning SW is input to TERMINAL (B) 2 of the
body ECU and the signal from the door courtesy SW LH is input to TERMINAL (C) 11 of body ECU. As a result, through
communication control of the body ECU etc. the buzzer in the combination meter goes on to warn the driver that the ignition
key is still inserted.
