mode (the hybrid system is not operating) for more than an hour with the shift
lever in P, the power switch will automatically turn off. However, this function
cannot entirely prevent 12-volt battery discharge. Do not leave the vehicle
with the power switch in ACCESSORY or ON mode for long periods of time
when the hybrid system is not operating.

■ Operation of the power switch
● If the switch is not pressed shortly and firmly, the power switch mode may
not change or the hybrid system may not start.
● If attempting to restart the hybrid system immediately after turning the power
switch off, the hybrid system may not start in some cases. After turning the
power switch off, please wait a few seconds before restarting the hybrid sys-
tem.

WARNING
■When starting the hybrid system
Always start the hybrid system while sitting in the driver’s seat. Do not
depress the accelerator pedal while starting the hybrid system under any
circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Caution while driving
If a hybrid system failure occurs while the vehicle is moving, do not lock or
open the doors until the vehicle reaches a safe and complete stop. Activa-
tion of the steering lock in this circumstance may lead to an accident, result-
ing in death or serious injury.
■ Stopping the hybrid system in an emergency
If you want to stop the hybrid system in an emergency while driving the
vehicle, press and hold the power switch for more than 3 seconds, or press
it briefly 3 times or more in succession. ( P. 395)
However, do not touch the power switch while driving except in an emer-
gency. Turning the hybrid system off while driving will not cause loss of
steering or braking control, however, power assist to the steering will be
lost. This will make it more difficult to steer smoothly, so you should pull over
and stop the vehicle as soon as it is safe to do so.

NOTICE
■To prevent 12-volt battery discharge
● Do not leave the power switch in ACCESSORY or ON mode for long peri-
ods of time without the hybrid system on.
● If the smart entry & start system indicator (green) is illuminated, the power
switch is not off. Exit the vehicle after turning the power switch off.
● Do not stop the hybrid system when the shift lever is in a position other
than P. If the hybrid system is stopped in another shift lever position, the
power switch will not be turned off but instead be turned to ACCESSORY
mode. If the vehicle is left in ACCESSORY mode, 12-volt battery dis-
charge may occur.
■ When starting the hybrid system
If the hybrid system becomes difficult to start, have your vehicle checked by
any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional immediately.
■ Symptoms indicating a malfunction with the power switch
If the power switch seems to be operating somewhat differently than usual,
such as the switch sticking slightly, there may be a malfunction.
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional immediately.

2444-6. Using the driving support systems
YARIS_HV_OM_Europe_OM52G76E
Driving assist systems
◆ECB (Electronically Controlled Brake System)
The electronically controlled system generates braking force corre-
sponding to the brake operation
◆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)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
◆TRC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
◆Hill-start assist control
Prevents the vehicle from rolling backward when starting on an
incline or slippery slope
◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel
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.

2464-6. Using the driving support systems
YARIS_HV_OM_Europe_OM52G76E
■Turning off both TRC and VSC systems
To turn the 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. 230)
■ Sounds and vibrations caused by the ABS, brake assist, TRC, VSC and
hill-start assist control systems
Any of the following conditions may occur when the above systems are oper-
ating. 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.
■ ECB operating sound
ECB operating sound may be heard in the following cases, but it does not
indicate that a malfunction has occurred.
● Operating sound heard from the engine compartment when the brake pedal
is operated.
● Motor sound of the brake system heard from the front part of the vehicle
when the driver’s door is opened.
● Operating sound heard from the engine compartment when one or two min-
utes passed after the stop of the hybrid system.
■ 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 power switch is turned off
● 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 hybrid system
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 hill-start assist control
When the following four conditions are met, the hill-start assist control will
operate:
● The shift lever is in a position other than P or 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.
■ Automatic system cancelation of hill-start assist control
The hill-start assist control will turn off in any of the following situations:
● The shift lever is moved to P or 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.
