4-2. Driving procedures
Driving
■Parking brake operation sound
When the parking brake operates, a motor sound (whirring sound) may be
heard. This does not indicate a malfunc-
tion.
■Parking brake operation

tion/mode, the parking brake indicator and parking brake light will turn on
and stay on as described below:

Not in ON: Stays on for approximately
15 seconds.
●When the engine switch is turned off
with the parking brake set, the parking brake indicator and parking brake light
will stay on for about 15 seconds. This
does not indicate a malfunction.
■When the parking brake switch malfunctions
Automatic mode (automatic brake set-
ting and releasing) will be turned on automatically.
■Parking the vehicle
 P.145

WA R N I N G
■When parking the vehicle
Do not leave a child in the vehicle
alone. The parking brake may be released unintentionally and there is
the danger of the vehicle moving that
may lead to an accident resulting in death or serious injury.
■Parking brake switch
Do not set any objects near the park- ing brake switch.
Objects may interfer e with the switch
and may lead the parking brake to unexpectedly operate.
NOTICE
■When parking the vehicle
Before you leave the vehicle, set the
parking brake, shift the shift lever to P
(Multidrive) or N (manual transmis- sion) and make sure that the vehicle
does not move.
■When the system malfunctions
Stop the vehicle in a safe place and
check the warning messages.
■When the parking brake cannot
be released due to a malfunction
Driving the vehicle with the parking brake set will lead to brake compo-
nents overheating, which may affect
braking performance and increase brake wear.
Have the vehicle inspected by any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer immediately if this occurs.

3184-5. Using the driving support systems
●Vehicles with a Multidrive: The shift
lever is shifted to P or N.
●Vehicles with a manual transmission:
The shift lever is shifted to R when starting off forward on an upward
incline, or the shift lever is shifted to
other than R when starting off back- ward on an upward incline.
●The accelerator pedal is depressed
●The parking brake is engaged
●2 seconds at maximum elapsed after
the brake pedal is released
■Sounds and vibrations caused by
the ABS, brake assist, VSC, TRC and hill-start assist control sys-
tems
●A sound may be heard from the
engine compartment when the brake
pedal is depressed repeatedly, 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 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.
■Active Cornering Assist operation
sounds and vibrations
When the Active Cornering Assist is
operated, operation sounds and vibra-
tions may be generated from the brake
system, but this is not a malfunction.
■EPS operation sound
When the steering wheel is operated, a
motor sound (whirring sound) may be
heard. This does not indicate a malfunc- tion.
■Automatic reactivation of TRC and
VSC systems
After turning the TRC and VSC systems
off, the systems will be automatically
re-enabled in the following situations:
●When the engine 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 re-enabling will
not occur when vehicle speed increases.
■Operating conditions of Active Cor-
nering Assist
The system operates when the following occurs.
●TRC/VSC can operate
●The driver is attempting to accelerate
while turning
●The system detects that the vehicle is
drifting to the outer side
●The brake pedal is released
■Reduced effectiv eness 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 nor- mal within 10 minutes.
■Operating conditions of emergency
brake signal
When the following conditions are met,
the emergency brake signal will oper- ates:
●The emergency flashers are off
●Actual vehicle speed is over 55 km/h
(35 mph)
●The system judges from the vehicle
deceleration that it is a sudden brak- ing operation.

ensure that they do not become entangled in the cooling fan or engine
drive belt.

ture gauge ( P.85, 88) is in
the red zone or a loss of
engine power is experienced.
(For example, the vehicle
speed does not increase.)
