Continued
Controls
Auto High-Beam
Using a camera mounted to the inside of the windshield, this system detects light 
sources ahead of the vehicle. Depending on the light source, the system 
automatically switches the headlights to hi gh beam for optimal visibility at night.1Auto High-Beam
The auto high-beam determines when to change the 
headlight beams by responding to the brightness of 
the lights ahead of your vehicle. In the following 
cases, the system may not respond to the lights 
properly:
•The brightness of the lights from the preceding or 
oncoming vehicle is intense or poor.
•Visibility is poor due to  the weather (rain, snow, 
fog, windshield frost, etc.).
•Other light sources, such  as street lights and 
electric billboards are illuminating the road ahead.
•The brightness level of th e road ahead constantly 
changes.
•The road is bumpy or has many curves.
•A vehicle cuts in front of you, or a vehicle in front 
of you is not in the preceding or oncoming 
direction.
•Your vehicle is tilted with a heavy load in the rear.
If you find the timing of beam changes inconvenient 
for driving, change the  headlight beams manually.
If you do not want the system  to be activated at any 
time when the headlight switch is in AUTO , consult a 
dealer or disable the system. 2 Disabling or Re-enabling the System  P. 179
■The headlight switch is in AUTO.■The lever is in the low beam 
position.
■The low beams are on and the 
system recognizes that you are 
driving at night.
■The vehicle speed is above 35 mph 
(56 km/h).
The system operates when:
When the camera detects lig hts coming from a preceding or oncoming vehicle, the 
headlights remain in low beam.
When the camera detects no lights coming  from a preceding or oncoming vehicle, 
the headlights change to high beam.
The view angle or distance that the camera can detect lights ahead differs 
depending on conditions, such as the brightness of the lights and the weather.

The high beams remain on unless:
•You have been driving below 25 mph (40 km/h) for an extended amount of time.
• The speed of the vehicle drops below 15 mph (24 km/h).
• The windshield wipers have been running at a high speed for more than a few 
seconds.

The high beams come back on once the condition that caused them to turn off no 
longer exists.
If needed, you can temporarily turn the  high beams off manually. Turn on the high 
beams by pushing the lever forward until yo u hear a click, or flash the high beams 
once by pulling the lever towards you. To turn the high beams back on, repeat one
