■When the sensors do not
operate properly
●In situations such as the follow-
ing, the sensors may not oper-
ate correctly, possibly leading to
an accident. Proceed carefully.
• When a sensor is frozen. (Thawing the area will resolve
this problem.) In especially cold
weather, if a sensor is frozen
the screen may show an abnor-
mal display, or parked vehicles
may not be detected.
• When the vehicl e is tilted at a
steep angle
• When it is extremely hot or cold
• When driving on rough, sloped, or gravel roads, or grass
• When ultrasonic waves are being produced near the vehicle
due to vehicle horns, motorcy-
cle engines, air brakes of large
vehicles, or the sensors of
another vehicle
• When it is raining or a sensor is splashed by water
• When the area around the vehi- cle is dark or backlit
• When a fender pole or radio antenna has been installed to
the vehicle
• When a sensor is extremely close to a parked vehicle
• When there is a parked vehicle next to the target parking space,
if the displayed target parking
space is far from the actual tar-
get parking space, a sensor
may be misaligned. Have the
vehicle inspected by your Toy-
ota dealer.
• Do not install any accessories near the detection area of the
sensors.
●The Advanced Park will guide
the vehicle to appropriate posi-
tions for changing the direction
of travel, however, if you feel
that the vehicle is approaching
too close to an adjacent parked
vehicle at any time, depress the
brake pedal and change the
shift position. However, if this is
performed, the number of turns
necessary may increase, and
the vehicle may be parked at an
angle.

trol systems
●A sound may be heard from the
fuel cell unit compartment when
the brake pedal is depressed
repeatedly, when the fuel cell sys-
tem is started or just after the vehi-
cle begins to move. This sound
does not indicate that a malfunc-
tion has occurred in any of these
systems.
●Any of the following conditions
may occur when t he above sys-
tems 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 also
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.

■Active Cornering Assist opera-
tion sounds and vibrations
When the Active Cornering Assist is
operated, operation sounds and
vibrations may be generated from
the brake system, but this is not a
malfunction.
■EPS operation sound
When the steering wheel is oper-
ated, a motor sound (whirring
sound) may be heard. This does not
indicate a malfunction.
■Automatic reactivation of TRAC
and VSC systems
After turning th e TRAC and VSC
systems off, the systems will be
automatically re-enabled in the fol-
lowing situations:
●When the power switch is turned
off
●If only the TRAC sy stem is turned
off, the TRAC will turn on when
vehicle speed increases
If both the TRAC and VSC sys-
tems are turned of f, automatic re-
enabling will not occur when vehi-
cle speed increases.

WARNING
●When Active Cornering Assist
frequently operates, Active Cor-
nering Assist may temporarily
stop operating to ensure proper
operation of the brakes, TRAC
and VSC.
■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 effec-
tively on steep inclines and
roads covered with ice.
●Unlike the parking brake, hill-
start assist control is not
intended to hold the vehicle sta-
tionary 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 acci-
dent.
■When the TRAC/ABS/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 systems
are turned off
Be especially careful and drive at
a speed appropriate to the road
conditions. As these are the sys-
tems to help ensure vehicle stabil-
ity and driving force, do not turn
the TRAC/VSC systems off
unless necessary.
■Secondary Collision Brake
Do not rely solely upon the Sec-
ondary Collision Brake. This sys-
tem is designed to help reduce
the possibility of further damage
due to a secondary collision, how-
ever, that effect changes accord-
ing to various conditions. Overly
relying on the system may result
in death or serious injury.
■Replacing tires
Make sure that all tires are of the
specified size, brand, tread pat-
tern and total load capacity. In
addition, make sure that the tires
are inflated to the recommended
tire inflation p ressure level.
The ABS, TRAC and VSC sys-
tems will not functi on correctly if
different tires are installed on the
vehicle.
Contact your Toyota dealer for fur-
ther information when replacing
tires or wheels.
■Handling of tires and the sus-
pension
Using tires with any kind of prob-
lem or modifying the suspension
will affect the driving assist sys-
tems, and may cause a system to
malfunction.
