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

WARNING
■Before using the LDA system
Do not rely solely on the LDA system. The LDA system does not drive the
vehicle automatically, nor does it reduce the amount of care you need to
take. As such, the driver must always assume full responsibility for under-
standing his/her surroundings, for operat ing the steering wheel to correct
the driving line, and for driving safely.
Inappropriate or negligent driving could lead to an accident.
■ To avoid operating the LDA by mistake
Switch the LDA system off using the LDA switch when not in use.
■ Situations unsuitable for LDA system
Do not use the LDA system in any of the following situations.
Otherwise, the system may not function correctly and could result in an
accident.
● When driving with tire chains, a spare tire, or similar equipment
● When there are objects or structures along the roadside that might be mis-
interpreted as lane markers (such as guardrails, a curb, reflector posts,
etc.)
● When driving on snowy roads
● When pavement lane markers are difficult to see due to rain, snow, fog,
sand, dirt, etc.
● When there are visible lines on the pavement from road repairs, or if the
remains of old lane markers are still visible on the road
● When driving on a road with lane closures due to maintenance, or when
driving in a temporary lane
NOTICE
■ To prevent damage to or incorrect operation of the LDA system
● Do not modify the headlights or attach stickers to the surface of the lights.
● Do not modify the suspension. If your suspension needs repairs, contact
any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional.
● Do not install or place anything on the hood or the grille. Also, do not install
a grille guard (bull bars, kangaroo bar etc.).

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.
