WARNING
■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not
come on when you start the engine, this could mean that these systems are
not available to help protect you in an accident, which could result in death
or serious injury. Have the vehicle inspected by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional
immediately if this occurs.
NOTICE
■ To prevent damage to the engine and its components
The engine may be overheating if the high engine coolant temperature
warning light flashes or turns on. In this case, immediately stop the vehicle
in a safe place, and check the engine after it has cooled completely.

WARNING
■Cautions regarding the assist functions of the system
By means of warnings and brake control, the pre-crash safety system is intended to assist the driver in avoiding collisions through the process ofLOOK-JUDGE-ACT. There are limits to the degree of assistance the system can provide, so keep in mind the following important points.
● Assisting the driver in watching the road The pre-crash safety system is only able to detect vehicles directly in frontof your vehicle, and only within a limi ted range. It does not allow for care- less or inattentive driving, and is not a system that can assist the driver in low-visibility conditions. It is still necessary for the driver to pay close atten- tion to the vehicle’s surroundings.
● Assisting the driver in making correct judgement When attempting to estimate the possibility of a collision, the only data available to the pre-crash safety system is that from vehicles it has detected directly in front of the vehicle. Therefore, it is absolutely neces-sary for the driver to remain vigila nt and to determine whether or not there is a possibility of collision in any given situation.
● Assisting the driver in taking action The pre-crash brake assist and pre- crash braking functions are designed to help avoid a collision or reduce the severity of a collision, as such theyonly operate when the system has determined that the possibility of a col- lision is high. This system is not capable of automatically avoiding a colli- sion or bringing the vehicle to a stop safely, without appropriate operationsbeing performed by the driver. For this reason, when encountering a dan-gerous situation the driver must take direct and immediate action in order to ensure the safety of all involved.
NOTICE
■ To avoid malfunction of the system
In the following situations, disable the pre-crash safety system. The system may operate even if there is no possibility of a collision.
● When inspecting the vehicle using a drum tester such as a chassis dyna- mometer or speedometer tester, or when using an on vehicle wheel bal-ancer
● When transporting the vehicle via boat, truck, or similar means of transpor- tation
● When the front part of the vehicle is raised or lowered, such as if tires of a different size than specified are used or if the suspension components are modified
● When the vehicle is being towed

Driving assist systems
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly,
or if the brakes are applied while driving on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake pedal
is depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control) (if equipped)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
◆TRC (Traction Control) (if equipped)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel
◆PCS (Pre-Crash Safety system) (if equipped)
 P. 2 2 7
◆Emergency brake signal
When the brakes are applied suddenly, the emergency flashers
automatically flash to alert the vehicle behind.
To help enhance driving safety and performance, the following
systems operate automatically in response to various driving
situations. Be aware, however, that these systems are supple-
mentary and should not be relied upon too heavily when operat-
ing the vehicle.

■Turning off both TRC and VSC systems
To turn TRC and VSC systems off, press and hold the VSC OFF switch for
more than 3 seconds while the vehicle is stopped.
The “TRC OFF” indicator and the VSC OFF indicator will come on.
Press the switch again to turn the systems back on.
On vehicles with pre-crash safety system, pre-crash brake assist and pre-
crash braking will also be disabled. The PCS warning light will come on.
( P. 233)
■ When the “TRC OFF” indicator comes on even if the VSC OFF switch
has not been pressed
TRC cannot be operated. Contact any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional.
■ Sounds and vibrations caused by the ABS, brake assist, TRC and VSC
systems
● A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, when the engine is started or just after the vehicle
begins to move. This sound does not indicate that a malfunction has
occurred in any of these systems.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■ Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automatically
re-enabled in the following situations:
● When the engine switch is turned to the “LOCK” position
● If only the TRC system is turned off, the TRC will turn on when vehicle
speed increases
If both the TRC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases.
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur, refrain
from excessive steering input or stop the vehicle and turn the engine off. The
EPS system should return to normal within 10 minutes.

■ If the slip indicator comes on
It may indicate a malfunction in the systems. Contact any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
■ Operating conditions of emergency brake signal
When the following three conditions are met, the emergency brake signal will
operate:
● The emergency flashers are off.
● Actual vehicle speed is over 55 km/h (35 mph).
● The brake pedal is depressed in a manner that cause the system to judge
from the vehicle deceleration that this is a sudden braking operation.
■ Automatic system cancelation of emergency brake signal
The emergency brake signal will turn off in any of the following situations:
● The emergency flashers are turned on.
● The brake pedal is released.
● The system judges from the vehicle deceleration that is not a sudden brak-
ing operation.
WARNING
■ The ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick roads.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten t he vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the
following situations:
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or roads with uneven surfaces
■ TRC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.

YARIS_F_WE_52G04E
WARNING
■When the VSC is activated
The slip indicator flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■ When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRC/VSC systems off unless unnecessary.
■ Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires
are installed on the vehicle.
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional for further in formation when replacing tires or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.
