Front Sensor Camera

Driving

Front Sensor Camera

The camera, used in systems such as LKAS, RDM, ACC, CMBS

, and auto high-

beam, is designed to detect an object that triggers any of the systems to operate
their functions.

This camera is located behind the rearview
mirror.

To help reduce the likelihood that high interior
temperatures will cause the camera’s sensing
system to shut off, when parking, find a shady
area or face the front of the vehicle away from
the sun. If you use a reflective sun shade, do
not allow it to cover the camera housing.
Covering the camera can concentrate heat on
it.

Camera Location and Handling Tips

Front Sensor Camera

Never apply a film or attach any objects to the
windshield, the hood, or the front grill that could
obstruct the camera’s field of vision and cause the
system to operate abnormally.
Scratches, nicks, and other damage to the windshield
within the camera’s field of vision can cause the
system to operate abnormally. If this occurs, we
recommend that you replace the windshield with a
genuine Honda replacement windshield. Making
even minor repairs within the camera’s field of vision
or installing an aftermarket replacement windshield
may also cause the system to operate abnormally.
After replacing the windshield, have a dealer
recalibrate the camera. Proper calibration of the
camera is necessary for the system to operate
properly.

Do not place an object on the top of the instrument
panel. It may reflect onto the windshield and prevent
the system from detecting lane lines properly.

Front Sensor Camera

If the Some Driver Assist Systems Cannot
Operate: Camera Temperature Too High message
appears:

•

Use the climate control system to cool down the
interior and, if necessary, also use defroster mode
with the airflow directed towards the camera.

•

Start driving the vehicle to lower the windshield
temperature, which cools down the area around
the camera.

If the Some Driver Assist Systems Cannot
Operate: Clean Front Windshield message
appears:

•

Park your vehicle in a safe place, and clean the
windshield. If the message does not disappear after
you have cleaned the windshield and driven for a
while, have your vehicle checked by a dealer.

Driving

Adaptive Cruise Control (ACC)

Helps maintain a constant vehicle speed and a set following-interval behind a vehicle
detected ahead of yours, without you having to keep your foot on the brake or the
accelerator.

Adaptive Cruise Control (ACC)

Important Reminder
As with any system, there are limits to ACC. Use the
brake pedal whenever necessary, and always keep a
safe interval between your vehicle and other vehicles.

Be careful not to severely impact the radar sensor
cover.

Shift up when the engine revolutions is increasing.
Shift down when the engine revolutions is decreasing.
You can keep the set speed if you change the shift
position within five second after depressing the
clutch pedal.

WARNING

Improper use of ACC can lead to a crash.

Use ACC only when driving on expressways or
freeways in good weather conditions.

WARNING

ACC has limited braking capability.

When your vehicle speed drops below
22 mph (35 km/h), ACC will automatically
cancel and no longer will apply your
vehicle’s brakes.

Always be prepared to apply the brake
pedal when conditions require.

P. 472

When not using ACC: Turn off adaptive cruise by
pressing the MAIN button. This also will turn off the
Lane Keeping Assist System (LKAS).

When the MAIN button is pressed both ACC and the
Lane Keeping Assist System (LKAS) are either turned
on or off.

ACC may not work properly under certain conditions.

2 ACC Conditions and Limitations P. 438

Do not use ACC under the following conditions:

•

On roads with heavy traffic or while driving in
continuous stop and go traffic.

•

On roads with sharp turns.

•

On roads with steep downhill sections, as the set
vehicle speed can be exceeded by coasting. In such
cases, ACC will not apply the brakes to maintain
the set speed.

•

On roads with toll collection facilities or other
objects between lanes of traffic, or in parking
areas, or facilities with drive through access.

There is a vehicle ahead

ACC monitors if a vehicle ahead of you enters the ACC range. If a vehicle is detected
doing so, the ACC system maintains or decelerates your vehicle’s set speed in order
to keep the vehicle’s set following-interval from the vehicle ahead.

2 To Set or Change Following-interval P. 441

When a vehicle whose speed is slower than
your set speed comes in or cuts in front of
you, your vehicle starts to slow down.

■

When in Operation

When in Operation

If the vehicle detected ahead of you slows down
abruptly, or if another vehicle is detected cutting in
front of you, the beeper sounds and a message
appears on the multi-information display.
Depress the brake pedal, and keep an appropriate
interval from the vehicle ahead.

Even if the interval between your vehicle and the
vehicle detected ahead is short, ACC may start
accelerating your vehicle under the following
circumstances:

•

The vehicle ahead of you is going at almost the
same speed as, or faster than, your vehicle.

•

A vehicle that cuts in front of you is going faster
than your vehicle, gradually increasing the interval
between the vehicles.

You can also set the system to beep when a vehicle in
front of you comes in and goes out of the ACC
detecting range. Change the ACC Forward Vehicle
Detect Beep setting.

■

There is no vehicle ahead

Your vehicle maintains the set speed without
having to keep your foot on the brake or
accelerator pedal.
If there previously was a vehicle detected
ahead that kept your vehicle from traveling at
the set speed, ACC accelerates your vehicle to
the set speed, and then maintains it.

■

When you depress the accelerator pedal

You can temporarily increase the vehicle speed. In this case, there is no audible or
visual alert even if a vehicle is in the ACC range.
ACC stays on unless you cancel it. Once you release the accelerator pedal, the
system resumes an appropriate speed for keeping the following-interval while a
vehicle ahead is within the ACC range.

When in Operation

Limitations
You may need to use the brake to maintain a safe
interval when using ACC. Additionally, ACC may not
work properly under certain conditions.

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 sensor cover is strongly
impacted, turn off the system by pressing the MAIN
button and take your vehicle to a dealer.

Have your vehicle checked by a dealer if you find any
unusual behavior of the system (e.g., the warning
message appears too frequently).

If the front of the vehicle is impacted in any of the
following situations, the radar sensor may not work
properly. Have your vehicle checked by a dealer:

•

The vehicle mounted onto a bump, curb, chock,
embankment, etc.

•

You drive the vehicle where the water is deep.

•

Your vehicle has a frontal collision.
