uuOperating the Switches Around the Steering Wheel uAuto High-Beam
Controls
Auto High-Beam
Using a camera mounted to the inside of the windshield, this system detects light
sources ahead of the vehicle. Depend ing 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. 182
■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:
How it works
When the camera detects lights 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.

When Driving
Turning on the Power
1.Make sure the parkin g brake is applied.
u The electric parking brake indicator
comes on for 15 seconds when you press
the electric parking brake switch.
2. Depress the brake pedal.1Turning on the Power
Keep your foot firmly on the brake pedal when
starting the power system.
The engine is harder to st art in cold weather and in
thinner air found at altitudes above 8,000 feet (2,400
meters).
When turning on the power system in cold weather,
turn off all electrical accessories such as the lights,
climate control system, and rear defogger in order to
reduce 12-volt battery drain.
If you live in a region where winter is extremely cold,
an engine block heater and transmission clutch
actuator heater will impr ove starting and warming of
the engine. Consult a dealer for details.
If the exhaust system sounds abnormal or you can
smell exhaust gas inside the vehicle, have your vehicle
checked by a dealer. There may be a problem with
the engine or exhaust system.

Driving
The system may automatically shut off and the ACC indicator will come on under
certain conditions. Some examples of these conditions are listed below. Other
conditions may reduce some of the ACC functions.

■Environmental conditions
Driving in bad weather (r ain, fog, snow, etc.).
■Roadway conditions
Driving on a snowy or wet roadway (obscure d lane marking, vehicle tracks, reflected
lights, road spra y, high contrast).
■Vehicle conditions
• The outside of the windshield is blocked by dirt, mud, leaves, wet snow, etc.
• An abnormal tire or wheel condition (Wrong sized, varied size or construction,
improperly inflated, compact spare tire
*, etc.).
• The camera temperature gets too high.
• The parking brake is applied.
• When the front grille is dirty.
• The vehicle is tilted due to a heavy load or suspension modifications.
• When tire chains are installed.
■ACC with LSF Conditions and Limitations1ACC with LSF Conditions and Limitations
The radar sensor for ACC with LSF is shared with the
Collision Mitigati on Braking System
TM (CMBSTM).
2 Collision Mitigation Braking SystemTM
(CMBSTM) P. 525
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 475
Always keep the radar sensor cover clean.
Never use chemical solvents or polishing powder for
cleaning the sensor cover. Clean it with water or a
mild detergent.
Do not put a sticker on the radar sensor cover or
replace the radar sensor cover.
If you need the radar sensor to be repaired, or
removed, or the radar se nsor cover is strongly
impacted, turn off the system by pressing the MAIN
button and take your vehicle to a dealer.

Driving
The system may not properly detect lane ma rkings and the position of your vehicle
under certain conditions. Some examples of these conditions are listed below.
■Environmental conditions
• Driving in bad weather (rain, fog, snow, etc.).
• Sudden changes between light and dark, such as an entrance or exit of a tunnel.
• There is little contrast between lane lines and the roadway surface.
• Driving into low sunlight (e.g., at dawn or dusk).
• Strong light is reflec ted onto the roadway.
• Driving in the shadows of trees, buildings, etc.
• Shadows of adjacent objects are parallel to lane markings.
• Roadway objects or structures are misinterpreted as lane markers.
• Reflections on the interi or of the windshield.
