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.

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) (vehicles with a VSC system)
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
◆Hill-start assist control (vehicles with a VSC system)
Prevents the vehicle from rolling backward when starting on a
incline or slippery slope.
◆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.

■Sounds and vibrations caused by the ABS, brake assist, VSC and TRC
systems
● A sound may be heard from the engine compartment 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
reactivated in the following situations:
● When the engine switch is turned to the “LOCK” position (vehicles without a
smart entry & start system) or off (vehicles with a smart entry & start sys-
tem).
● 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 reactivation 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.
■ Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assist control will
operate:
● Vehicles with a multi-mode manual transmission: The shift lever is in a posi-
tion other than N (when starting off forward/backward on an upward incline).
● The vehicle is stopped.
● The accelerator pedal is not depressed.
● The parking brake is not engaged.

1944-5. Using the driving support systems
AYGO_EE_OM99J92E
■ Automatic system cancelation of hill-start assist control
The hill-start assist control will turn off in any of the following situations:
● Vehicles with a multi-mode manual transmission: The shift lever is moved to
N.
● The accelerator pedal is depressed.
● The parking brake is engaged.
● Approximately 2 seconds elapse after the brake pedal is released.
■ 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 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.

WARNING
■ Hill-start assist control does not operate effectively when
● Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on steep inclines and roads covered with ice.
● Unlike the parking brake, hill-start assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.
■ When the VSC is activated
The slip indicator light 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 necessary.
■ 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.
