2012 TOYOTA PRIUS C parking brake

204 2-3. Operating the lights and wipers
■Daytime running light system
●To make your vehicle more visible to other drivers, the headlights turn on
automatically (at a reduced intensity) whenever the hybrid system is
started and the parking brake is released. Daytime running lights are not
designed for use at night.
For type A: Daytime running lights can be turned off by operating the
switch.
● Compared to turning on the headlights, the daytime running light system
offers greater durability and consumes less electricity, so it can help
improve fuel economy.
■ Light reminder buzzer
Vehicles without a smart key system
A buzzer sounds when the engine switch is turned to the “LOCK” or “ACC”
position and the driver's door is opened while the lights are turned on.
Vehicles with a smart key system
A buzzer sounds when the “POWER” switch is turned off or turned to
ACCESSORY mode and the driver's door is opened while the lights are
turned on.
■ Battery-saving function
In the following conditions, the remaining lights will go off automatically after
20 minutes in order to prevent the vehicle battery from being discharged:
●The headlights and/or tail lights are on.
● The engine switch is turned to the “ACC” or “LOCK” position (vehicles
without a smart key system) or the “P OWER” switch is turned to ACCES-
SORY mode or turned off (vehicles with a smart key system).
This function will be canceled in any of the following situations:
● When the engine switch is turned to the “ON” position (vehicles without a
smart key system) or the “POWER” switch is turned to ON mode (vehi-
cles with a smart key system).
● When the light switch is operated.
● When the door is opened or closed.

Hill-start assist control
■Hill-start assist control operating conditions
●The system operates in the following situations:
• The shift lever is in a position other than P.
• The parking brake is not applied.
• The accelerator pedal is not depressed.
● Hill-start assist control cannot be operated while the slip indicator light is
illuminated.
■ Hill-start assist control
●While hill-start assist control is operating, the brakes remain automati-
cally applied after the driver releases the brake pedal. The stop lights and
the high mounted stoplight turn on.
● Hill-start assist control operates for about 2 seconds after the brake pedal
is released.
● If the slip indicator does not flash and the buzzer does not sound when
the brake pedal is further depressed, slightly reduce the pressure on the
brake pedal (do not allow the vehicl e to roll backward) and then firmly
depress it again. If the system still does not operate, check that the oper-
ating conditions explained above have been met.
Assists with starting off and tem porarily maintains braking power
even if the foot is re moved from the brake peda l when starting off on
an incline or a slippery slope.
To engage hill-start assist con-
trol, further depress the brake
pedal when the vehicle is
stopped completely.
A buzzer will sound once to
indicate the system is acti-
vated. The slip indicator will
also start flashing.

When driving
■Hill-start assist control buzzer
●When hill-start assist control is activated, the buzzer will sound once.
● In the following situations, hill-start assist control will be canceled and the
buzzer will sound twice.
• No attempt is made to drive the vehicle within approximately 2 seconds
of releasing the brake pedal.
• The shift lever is moved to P.
• The parking brake is applied.
• The brake pedal is depressed again.
• The brake pedal has been depressed for more than approximately 3 minutes.
● If a buzzer other than the hill-start assist control buzzer is sounding, the
hill-start assist control buzzer may not sound.
■ If the slip indicator comes on
It may indicate a malfunction in the system. Contact your Toyota dealer.
CAUTION
■Hill-start assist control
●Do not overly rely on hill-start assist control. 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.
