■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.
■ Automatically P positi on selection function
P. 186
■ When the shift control system malfunctions
The power switch will not be able to be turned off. In such a case, the switch
can be turned off after applying the parking brake.
Have the vehicle inspected by your Toyota dealer immediately.
■ Meter display
When the power switch is turned off, each display will turn off as follows.
●The shift position indicator will turn off after approximately 2 seconds.
● EV driving ratio and average fuel consumption after hybrid system started,
turn off after approximately 6 seconds.
● The odometer, clock, etc. will turn off after approximately 30 seconds.
(Each display will also turn off immediately if a door is locked before 30 sec-
onds has elapsed.)
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.
■ Stopping the hybrid syst em 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 2 seconds, or press
it briefly 3 times or more in succession. ( P. 485)
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.

4-5. Using the driving support systems
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
◆TRAC (Traction Control)
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 redu ce the amount of effort needed to
turn the steering wheel
◆Enhanced VSC (Enhanced Ve hicle Stability Control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional st ability when swerving on slippery
road surfaces by controllin g steering performance.
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, TRAC 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 1 or 2 minutes

4-5. Using the driving support systems
■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.
■ Automatic reactivation of TRAC system
After turning the TRAC system off, the system will be automatically re-
enabled in the following situations:
●When the power switch is turned off
● The TRAC will turn on when vehicle speed increases
■ Electric power steering system warning light (warning buzzer)
P. 493

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 road.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the 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
■ TRAC may not operat e effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.
■ Hill-start assist control does not operate effectively when
●Do not overly rely on the hill-start assist control. The 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 TRAC/VSC syst em is turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As this is the system to help ensure vehicle stability and driving force,
do not turn the TRAC/VSC system off unless necessary.
