The indicator comes on when the ASC
system is on.
When the dial is turned to the lowest
volume, the ASC system will be turned

The ASC system can be operated when
The driving mode select switch is in normal mode or sport mode. (
■
Temporary cancelation of the ASC system functions
The ASC system may be temporarily canceled depending on the driving conditions,
such as when the tires slip due to sudden acceleration.
ASC (Active Sound Control)
(RC350/RC300)
: If equipped
The ASC system is an electronic sound system that generates engine sound,
conveying the kinetic situations of the vehicle’s acceleration and deceleration
to the driver through the speakers inside the instrument panel.
The vehicle’s response to the driver’s acceleration behavior and shift opera-
tions are also conveyed in sound.
When sport mode is selected, the sound conveyed to the driver will be louder.

ASC (Active Sound Control)
(RC F)
: If equipped
The ASC system sonically emphasizes the vehicle’s response to the driver’s
operation of the accelerator pedal and shift lever or paddle shift switches. The
dynamic engine sound enabled by this system helps the driver further enjoy
the feeling of unity with the vehicle, particularly when driving in M mode.

With the headlights on, push the
lever away from you to turn on the
high beams.
Pull the lever toward you to the center
position to turn the high beams off.
Pull the lever toward you and release
it to flash the high beams once.
You can flash the high beams with the

■
Daytime running light system
●
The daytime running lights illuminate using the same lights as the parking lights and illu-
minate brighter than the parking lights.
●
To make your vehicle more visible to other drivers during daytime driving, the daytime
running lights turn on automatically when all of the following conditions are met. (The
daytime running lights are not designed for use at night.)
• The engine is running
• The parking brake is released
• The headlight switch is in the
(Canada only),
or
*
position
*
: When the surroundings are bright
The daytime running lights remain on after they illuminate, even if the parking brake is set
again.
●
For the U.S.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.
●
Vehicles with LED front turn signal lights: If a turn signal light is in use, the daytime run-
ning light, on the same side, is turned off. For emergency flashers, both are turned off.

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.

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 engine switch is turned off or turned to ACCESSORY mode
and the driver’s door is opened while the lights are turned on.

necessary.
WARNING
■
Limitations of the Automatic High Beam
Do not overly rely on the Automatic High Beam. Always drive safely, taking care to
observe your surroundings and turning the high beams on or off manually if necessary.

Conditions to turn the high beams on/off automatically
●
When all of the following conditions are met, the high beams will be turned on automat-
ically (after approximately 1 second):
• The vehicle speed is approximately 21 mph (34 km/h) or more.
• The area ahead of the vehicle is dark.
• There are no vehicles ahead with headlights or tail lights turned on.
• There are few streetlights on the road ahead.
●
If any of the following conditions is met, the high beams will turn off automatically:
• The vehicle speed is below approximately 17 mph (27 km/h).
• The area ahead of the vehicle is not dark.
• Vehicles ahead have their headlights or tail lights turned on.
• There are many streetlights on the road ahead.
■
Camera sensor detection information
●
The high beams may not be automatically turned off in the following situations:
• When a vehicle suddenly appears from around a curve
• When the vehicle is cut in front of by another vehicle
• When vehicles ahead cannot be detected due to repeated curves, road dividers or
roadside trees
• When vehicles ahead appear in a faraway lane on a wide road
• When the lights of vehicles ahead are not on
●
The high beams may be turned off if a vehicle ahead that is using fog lights without its
headlights turned on is detected.
●
House lights, street lights, traffic signals, and illuminated billboards or signs and other
reflective objects may cause the high beams to change to the low beams, or the low
beams to remain on.
●
The following factors may affect the amount of time taken for the high beams to turn on
or off:
• The brightness of the headlights, fog lights, and tail lights of vehicles ahead
• The movement and direction of vehicles ahead
• When a vehicle ahead only has operational lights on one side
• When a vehicle ahead is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of the road surface, etc.)
• The number of passengers and amount of luggage in the vehicle
●
The high beams may turn on or off unexpectedly.

●
Bicycles or similar vehicles may not be detected.
●
In the following situations the system may not be able to correctly detect the surround-
ing brightness level. This may cause the low beams to remain on or the high beams to
flash or dazzle pedestrians or vehicles ahead. In such a case, it is necessary to manually
switch between the high and low beams.
• When driving in inclement weather (heavy rain, snow, fog, sandstorms, etc.)
• When the windshield is obscured by fog, mist, ice, dirt, etc.
• When the windshield is cracked or damaged
• When the camera sensor is deformed or dirty
• When the temperature of the camera sensor is extremely high
• When the surrounding brightness level is equal to that of headlights, tail lights or fog
lights
• When headlights or tail lights of vehicles ahead are turned off, dirty, changing color,
or not aimed properly
• When the vehicle is hit by water, snow, dust, etc. from a preceding vehicle
• When driving through an area of intermittently changing brightness and darkness
• When frequently and repeatedly driving ascending/descending roads, or roads with
rough, bumpy or uneven surfaces (such as stone-paved roads, gravel roads, etc.)
• When frequently and repeatedly taking curves or driving on a winding road
• When there is a highly reflective object ahead of the vehicle, such as a sign or mirror
• When the back of a preceding vehicle is highly reflective, such as a container on a
truck
• When the vehicle's headlights are damaged or dirty, or are not aimed properly
• When the vehicle is listing or titling due to a flat tire, a trailer being towed, etc.
• When the headlights are changed between the high beams and low beams repeat-
edly in an abnormal manner
• When the driver believes that the high beams may be flashing or dazzling pedestri-
ans or other drivers
■
Temporarily lowering sensor sensitivity
The sensitivity of the sensor can be temporarily lowered.
Turn the engine switch off while the following conditions are met.
• The headlight switch is in
or
.
• The headlight switch lever is in high beam position.
• Automatic High Beam switch is on.
Turn the engine switch to IGNITION ON mode.
Within 30 seconds after , repeat pulling the headlight switch lever to the original
position then pushing it to the high beam position quickly 10 times, then leave the lever
in high beam position.
If the sensitivity is changed, the Automatic High Beam indicator is turn on and off 3
times.
