Even when performing the following actions with the intent of enabling engine braking,
engine braking will not activate because cruise control, dynamic radar cruise control or
dynamic radar cruise control with full-speed range will not be canceled.
●While driving in S mode, downshifting to 5 or 4. ( P. 2 0 9 )
●When switching the driving mode to sp ort mode while driving in D position.

■Daytime running light system
●To make your vehicle more visible to other drivers during daytime driving, the daytime
running lights turn on automatically (at an in creased intensity) whenever the hybrid sys-
tem is started and the parking brake is releas ed with the headlight switch off or in the
“AUTO” position. (Illuminate brighter than the front parking lights.) Daytime running
lights are not designed for use at night.
Type A only: Daytime running lights can be turned off by operating the switch.
●If a turn signal light is in use, the daytime running light, on the same side, is turned off.
For emergency flashers, both are turned off.
●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.
■Headlight control sensor
■Automatic light off system
●When the headlights come on: The headlights and tail lights turn off 30 seconds after a
door is opened and closed if the power switch is turned to ACCESSORY mode or
turned off. (The lights turn off immediately if on the key is pressed after all the doors
are locked.)
●When only the tail lights come on: The tail lights turn off automatically if the power
switch is turned to ACCESSORY mode or turned off and the driver’s door is opened.
To turn the lights on again, turn the power switch to ON mode, or turn the light switch off
once and then back to or .
■Automatic headlight leveling system (if equipped)
The level of the headlights is automatically ad justed according to the number of passen-
gers and the loading condition of the vehicle to ensure that the headlights do not inter-
fere with other road users.
■Light reminder buzzer
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.
■12-volt battery-saving function
In order to prevent the 12-volt battery of the vehicle from discharging, if the headlights
and/or tail lights are on when the power switch is turned off the 12-volt battery saving
function will operate and automatically turn off all the lights after approximately 20 min-
utes. When the power switch is turned to ON mode, the 12-volt battery-saving function
will be disabled.
When any of the following are performed, the 12-volt battery-saving function is canceled
once and then reactivated. All the lights w ill turn off automatically 20 minutes after the
12-volt battery-saving function has been reactivated:
●When the headlight switch is operated
●When a door is opened or closed
The sensor may not function properly if an
object is placed on the sensor, or anything 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.
