2015 HONDA ACCORD sensor

uuWhen Driving uAdaptive Cruise Control (ACC)
*
450Driving
The radar sensor monitors the distance between your vehicle and a vehicle ahead of
you. When the sensor detects a change in distance, the system responds it by
accelerating or braking your vehicle in order to maintain the set speed and following
distance as necessary.■
When in Operation
1 When in Operation
If the vehicle ahead of you slows down abruptly, or if
another vehicle cuts in front of you, the beeper
sounds and a message appears on the multi-
information display to alert you to brake.
Depress the brake pedal, and keep an appropriate
distance from the vehicle ahead.
Even if the distance between your vehicle and the
vehicle ahead is short, FCW may not alert you or 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 cuts in front of you is going faster than
your vehicle, gradually distancing itself from you.
If you do not want to hear a beep when the system
detects a vehicle, or when the vehicle goes out of
ACC range, you can change the pre-running detect
car beep setting. 2 Customized Features P. 97, 298

■When ACC detects a
vehicle within ACC range:
■When the vehicle goes
out of ACC range:
The beeper sounds once and
the vehicle icon appears on the
multi-information display. The beeper sounds once
and the vehicle icon on the
multi-information display

To cancel adaptive cruise control, do any of
the following:
• Press the CANCEL button.
• Press the MAIN button.
u ACC Off appears on the multi-
information display.
• Depress the brake pedal.
■Automatic cancellation
The beeper sounds and a message appears on the multi-information display when
ACC is automatically canceled. Any of these conditions may cause the ACC
cancellation:
• Your vehicle speed slows down to 22 mph (35 km/h) and below.
• Bad weather (rain, fog, snow, etc.).
• When the radar sensor inside the front grille gets dirty.
• The vehicle ahead of you cannot be detected.
• An abnormal tire condition is detected, or the tires are skidding.
• Driving on a mountainous road, or driving off road for extended periods.
• Abrupt steering wheel movement.
• When the ABS or VSA is activated.
• When the ABS or VSA indicator comes on.■

Resuming the prior set speed: After you have
canceled adaptive cruise control, you can resume the
prior set speed while it is still displayed. Press the
RES/+ button when driving at a speed of at least 25
mph (40 km/h) or more.
You cannot set or resume in the following situations:•When vehicle speed is less than 25 mph (40 km/h).•When the MAIN button is turned off.

uuWhen Driving uForward Collision Warning (FCW)

Driving
Forward Collision Warning (FCW)
*
Alerts you when it determines that there is a possibility that your vehicle may collide
with a vehicle detected in front of yours.
If the system determines a collision is possible, it gives both visual and audible alerts,
including a head-up warning that flashes on the windshield.
u Take appropriate action to prevent a collision (apply the brakes, change lanes,
etc.).■How the system works
The system may give warnings of potential collisions when your vehicle speed is
above 10 mph (15 km/h).
1 Forward Collision Warning (FCW)
*
Important Safety Reminder
FCW cannot detect all objects ahead and may not
detect a given object; accuracy of the system will vary
based on weather, speed and other factors. FCW
does not include a braking function. It is always your
responsibility to safely operate the vehicle and avoid
collisions.
You can change the Forward Collision Warning
Distance setting or turn the system on and off.
2 Customized Features P. 97, 298
For the FCW system to work properly:•Always keep the radar sensor cover clean.•Never use chemical solvents or polishing
compounds to clean the sensor cover. Instead,
clean it with water and a mild detergent.•Do not put anything on the radar sensor cover.
See a dealer if the radar sensor gets damaged or
requires repair.
The camera is shared wi th Lane Departure Warning
(LDW).

Driving
1Forward Collision Warning (FCW)
*
Never apply a film or attach any objects to the
windshield that could obstruct the FCW camera's
field of vision.
Scratches, nicks, and other damage to the windshield
within the FCW 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 FCW
camera is necessary for the system to operate
properly.Models with information display1 How the system works
The head-up warning uses a lens located at the front
end of the dashboard.
Do not cover the lens or spill any liquid on it.

■Automatic shutoff
FCW may automatically shut itself off and the FCW indicator comes and stays on when:
• The temperature inside the system is high.
• The windshield is blocked by dirt, mud, leaves, wet snow, etc.
• You drive off-road or on a mountain road, or curved and winding road for an
extended period.
• You drive in bad weather (rain, fog, snow, etc.).
• The radar sensor cover is blocked by dirt, mud, leaves, wet snow, etc.
• An abnormal tire condition is detected (wrong tire size, flat tire, etc.).
Once the conditions that caused FCW to shut off improve or are addressed (e.g.,
cleaning), the system comes back on.
1 Automatic shutoff
To help reduce the likelihood that high interior
temperatures will cause the camera 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 the camera.
If the CAMERA HOT message appears:•Use the climate control system to cool down the
interior and, if necessary, the defroster mode when
windows are fogged.•Start driving the vehicle to lower the windshield
temperature, which cools down the area around
the FCW system.Models with information display
