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.
