WARNING
■When starting the fuel cell system
Always start the fuel cell system while sitting in the driver’s seat. Do not
depress the accelerator pedal while starting the fuel cell syst em under any
circumstances.
Doing so may cause an accident resulting in death or serious in jury.
■ Stopping the fuel cell system in an emergency
If you want to stop the fuel cell system in an emergency while driving the
vehicle, press and hold the power switch for more than 2 second s, or press
it briefly 3 times or more in succession. ( P. 361)
However, do not touch the power switch while driving except in an emer-
gency. Turning the fuel cell system off while driving will not cause loss of
steering or braking control, however, power assist to the steer ing will be
lost. This will make it more difficult to steer smoothly, so yo u should pull over
and stop the vehicle as soon as it is safe to do so.
NOTICE
■ To prevent 12-volt b attery discharge
Do not leave the power switch in ACCESSORY or ON mode for long peri-
ods if the fuel cell system is off.
■ When starting the fuel cell system
If the fuel cell system becomes difficult to start, have your vehicle checked
by your Toyota dealer 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 malfunctio n. Contact
your Toyota dealer immediately.

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 suddenl y,
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 p edal
is depressed when the system de tects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
◆Enhanced VSC (Enhanced Vehicle Stability Control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippe ry
road surfaces by controlling steering performance.
◆TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicl e or accelerating on slippery roads
◆Hill-start assist control
Helps to prevent the vehicle from rolling backward when startin g on
an incline.
To help enhance driving safety and performance, the following
systems operate autom atically 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 TRAC and VSC systems
To turn the TRAC and VSC systems off, press and hold for more than 3
seconds while the vehicle is stopped.
The VSC OFF indicator will come on and the “TRAC OFF” is displa yed on the
multi-information display.
Press again to turn the systems back on.
Pre-collision brake assist and pre-collision braking will also be disabled. The
PCS warning light will come on and the message is shown on the multi-infor-
mation display. ( P. 241)
■ When the message is displayed on the multi-information display show-
ing that TRAC has been disab led even if has not been pressed
TRAC and hill-start assist control cannot be operated. Contact your Toyota
dealer.
■ 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 system s 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 activat ed.
■ 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 motor compartment when the brake ped al is
operated.
● Motor sound of the brake system heard from the front part of th e vehicle
when the driver’s door is opened.
● Operating sound heard from the motor compartment when 1 or 2 mi nutes
passed after the stop of the fuel cell system.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring so und) may be
heard. This does not indicate a malfunction.

2345-5. Using the driving support systems
MIRAI_OM_USA_OM62025U■
Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the s ystem from
overheating when there is frequent steering input over an exten ded period of
time. The steering wheel may feel heavy as a result. Should thi s occur, refrain
from excessive steering input or stop the vehicle and turn the fuel cell system
off. The EPS system should return to normal within 10 minutes.
■ Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
● When the power switch is turned off
● If only the TRAC system is turned off, the TRAC will turn on wh en vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-e nabling will
not occur when vehicle speed increases
■ Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assi st control will
operate:
● The shift position is in a position other than P or N (when sta rting 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 follo wing situations:
● Shift the shift position to P or N.
● The accelerator pedal is depressed.
● The parking brake is engaged.
● Approximately 2 seconds elapse after the brake pedal is release d.
■ Operating conditions of emergency brake signal
When the following three conditions are met, the emergency brak e signal will
operate:
● The emergency flashers are off.
● Actual vehicle speed is over 35 mph (55 km/h).
● The brake pedal is depressed in a manner that cause the system to judge
from the vehicle deceleration that this is a sudden braking ope ration.
■ Automatic system cancelation of emergency brake signal
The emergency brake signal will turn off in any of the followin g situations:
● The emergency flashers are turned on.
● The brake pedal is released.
● The system judges from the vehicle deceleration that is not a s udden brak-
ing operation.

WARNING
■The ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded (suc h as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or s lick roads.
■ 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, espe cially 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 operate effectively when
Directional control and power may not be achievable while drivi ng on slip-
pery road surfaces, even if the TRAC system is operating.
Drive the vehicle carefully in conditions where stability and p ower may be
lost.
■ Hill- start assist control does not operate effectively when
● Do not overly rely on the hill-start assist control. The hill-s tart assist control
may not operate effectively on steep inclines and roads covered with ice.
● Unlike the parking brake, hill-start assist control is not inte nded 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 TRAC, VSC and/or ABS is activated
The slip indicator flashes. Always drive carefully. Reckless dr iving may
cause an accident. Exercise particular care when the indicator flashes.
■ When the TRAC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the r oad condi-
tions. As these are the systems to help ensure vehicle stabilit y and driving
force, do not turn the TRAC/VSC systems off unless necessary.
