When driving
When stopping the hybrid system with the shift lever in a
position other than P
If the hybrid system is stopped with the shift lever in a position other
than P, the “POWER” switch will not be turned off but instead be
turned to ACCESSORY mode. Perform the following procedure to
turn the switch off:
Check that the parking brake is set.
Shift the shift lever to P.
Check that is displayed on the multi-information dis-
play and then press the “POWER” switch once.
Check that on the multi- information display is off.
■Auto power off function
When the shift lever is in P, if the vehicle is left in ACCESSORY or ON mode
with the hybrid system not operating for more than 20 minutes (ACCES-
SORY mode) or one hour (ON mode), the “POWER” switch will automati-
cally turn off. However, this function cannot entirely prevent 12-volt battery
discharge. Do not leave the vehicle with the “POWER” switch in ACCES-
SORY or ON mode for long periods of time when the hybrid system is not
operating.

■The clock is displayed when
Vehicles without a smart key system
The engine switch is in the “ON” position.
Vehicles with a smart key system
The “POWER” switch is in ON mode.
■ Eco score
●As the accelerator pedal is not depressed, the driven distance using
cruise control (if equipped) is not included in the eco score.
● As the eco score evaluation differs according to driving conditions and
environmental factors, in some cases it may not be linked to fuel con-
sumption.
■ Eco savings
●Fuel cost and savings should be used as a guide only.
● Depending on refueling methods, driving conditions and environmental
factors, the actual and displayed fuel costs may differ.
● In some cases, fuel cost and savings may not be linked to the eco score
evaluation.
■ When disconnecting and reconnect ing 12-volt battery terminals
The following information data will be reset:
● Clock
● Past record (aside from the top 3 results)
● Average fuel consumption
● Cruising range
● Average vehicle speed
● Driving time
● EV driving rate/EV driven distance
Additionally, some displays may return to their default settings.
■ Liquid crystal display
Small spots or light spots may appear on the display. This phenomenon is
characteristic of liquid crystal displays, and there is no problem continuing to
use the display.

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.
