Brake Hold
Turns the brake hold system on
The brake hold standby indicator
(green) comes on. While the sys-
tem is holding the brake, the brake
hold operated indicator (yellow)
comes on.
Brake hold system operating conditions
The brake hold system cannot be turned on in the following conditions:
The trunk or hood is not closed.
The driver’s door is not closed.
The driver is not wearing the seat belt.
If any of the conditions above are detected when the brake hold system is
enabled, the system will turn off and the brake hold standby indicator light
will go off. In addition, if any of the conditions are detected while the system
is holding the brake, a warning buzzer will sound and a message will be
shown on the multi-information display. The parking brake will then be set
automatically.
Brake hold function
If the brake pedal is left released for a period of about 3 minutes after the
system has started holding the brake, the parking brake will be set automat-
ically. In this case, a warning buzzer sounds and a message is shown on the
multi-information display.
To turn the system off while the system is holding the brake, firmly depress
the brake pedal and press the button again.
The brake hold system keeps the brake applied when the shift lever
is in D, S or N with the system on and the brake pedal has been
depressed to stop the vehicle. The system releases the brake when
the accelerator pedal is depressed with the shift lever in D or S to
allow smooth start off.

Daytime running light system
To make your vehicle more visible to other drivers, the front position lights
turn on automatically whenever the hybrid system is started and the parking
brake is released. Daytime running lights are not designed for use at night.
Headlight control sensor
Automatic light off system
When the light switch is in : The headlights turn off automatically if the
power switch is turned to ACCESSORY mode or turned off.
When the light switch is in : The headlights and all lights turn off auto-
matically if the power switch is turned to ACCESSORY mode or turned off.

SORY mode and the driver’s door is opened while the lights are turned on.
Automatic headlight leveling system
The level of the headlights is automatically adjusted according to the number
of passengers and the loading condition of the vehicle to ensure that the
headlights do not interfere with other road users. The sensor may not function properly if
an object is placed on the sensor, or any-
thing that blocks the sensor is affixed to
the windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight system
to malfunction.
