Front Sensor Camera
*
The camera, used in systems such as LDW, FCW with Pedestrian Detection, LKAS,
RDM, ACC with LSF, and CMBS
TM, is designed to detect an object that triggers any
of the systems to operate its functions.
This camera is located behind the rearview
mirror.
To help reduce the likelihood that high interior
temperatures will cause the camera’s sensing

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
1Front Sensor Camera
*
Never apply a film or attach any objects to the
windshield that could obstruct the camera’s field of
vision.
Scratches, nicks, and other damage to the windshield
within the ca mera’s field of vision can cause the
system to operate abnormally. If this occurs, we
recommend that you replace the windshield with a
genuine Acura replacement windshield. Making even
minor repairs withi n 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.
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 air flow directed towards the camera.•Start driving the vehicle to lower the windshield
temperature, which cools down the area around
the camera.

Driving
Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)
*
Helps maintain a constant vehicle speed and a set following-distance behind a
vehicle detected ahead of yours and, if the detected vehicle slows to a stop,
decelerates and stops your vehicle, without you having to keep your foot on the
brake or the accelerator.

3
WARNING
Improper use of ACC with LSF can lead to a
crash.
Use ACC with LSF only when driving on
expressways or freeways and in good
weather conditions.
3
WARNING
ACC with LSF has limited braking capability
and may not stop your vehicle in time to
avoid a collision with a vehicle that quickly
stops in front of you.
Always be prepared to apply the brake
pedal if the conditions require.
3
WARNING
Exiting a vehicle that has been stopped
while the ACC with LSF system is operating
can result in th e vehicle moving without
operator control.
A vehicle that moves without operator
control can cause a crash, resulting in
serious injury or death.
Never exit a vehicle when the vehicle is
stopped by ACC with LSF.
When to use■Vehicle speed for ACC with LSF: A vehicle is detected ahead within ACC with
LSF range – ACC with LSF operates at speeds up to 90 mph (145 km/h).
No vehicle is detected within ACC with LSF range – ACC with LSF operates at
the speed of about 25 mph (40 km/h) or above.■Gear position for ACC with LSF: In
( D. The radar sensor is in
the front grille.
The camera is
located behind the
rearview mirror.

Important Reminder
As with any system, there are limits to ACC with LSF.
Use the brake pedal whenever necessary, and always
keep a safe distance between your vehicle and other
vehicles.
The radar sensor for ACC with LSF is shared with the
Collision Mitigation Braking System
TM (CMBS
TM).

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.2 Front Sensor Camera
* P. 351
■Environmental conditions
• Driving in bad weather (rain, fog, snow, etc.).■Roadway conditions
• Driving on a snowy or wet roadway (obscured lane marking, vehicle tracks,
reflected lights, road spray, 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 hot.
• The parking brake is applied.

Driving
■Detection limitations
• A vehicle or pedestrian suddenly crosses in front of you.
• The distance between your vehicle and the vehicle or pedestrian ahead of you is
too short.
• A vehicle or pedestrian cuts in front of you at a slow speed, and it brakes
suddenly.
• When you accelerate rapidly and approach the vehicle or pedestrian ahead of you
at high speed.
• The vehicle ahead of you is a motorcycle, bicycle, mobility scooter, or other small
vehicle.
• When there are animals in front of your vehicle.
• When you drive on a curved or winding or undulating road that makes it difficult
for the sensor to properly detect a vehicle or a pedestrian in front of you.
• The speed difference between your vehicle and a vehicle in front of you is
significantly large.
• An oncoming vehicle suddenly comes in front of you.
• Your vehicle abruptly crosses over in front of an oncoming vehicle.

■Automatic cancellation
The beeper sounds and a message appears on the multi-information display when
ACC with LSF is automatically canceled. Any of these conditions may cause the ACC
with LSF to automatically cancel:
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor in 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, VSA ® or CMBS
TM is activated.
• When the ABS or VSA ® system indicator comes on.
• When the vehicle is stopped on a very steep slope.
• When you manually apply the parking brake.
• When the detected vehicle within the ACC with LSF range is too close to your
vehicle.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
The ACC with LSF automatic cancellation can be also triggered by the following
causes. In these cases, the parking brake will be automatically applied.
• The driver’s seat belt is unfastened when the vehicle is stationary.
• The vehicle stops for more than 10 minutes.
• The engine is turned off.
1Automatic cancellation
Even though ACC with LSF has been automatically
canceled, you can still resume the prior set speed.
Wait until the condition that caused ACC with LSF to
cancel improves, then press the RES/+/SET/– switch
up.

Forward Collision Warning (FCW) with Pedestrian Detection
*
Alerts you when it determines the possibility of your vehicle colliding with a vehicle
or pedestrian detected in front of you.
If the system determines a collision is possible, it gives visual and audible alerts.
u Take appropriate action to prevent a collision (apply the brakes, change lanes,
etc.).■How the system works
For a possible collision with a vehicle: Warnings may be given when your vehicle
speed is about 10 mph (15 km/h) and above.
For a possible collision with a pedestrian: Warnings may be given when your vehicle
speed is between about 10 and 62 mph (15 and 100 km/h).
1 Forward Collision Warning (FCW) with Pedestrian Detection
*
Important Safety Reminder
FCW with Pe destrian Detection 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 with Pedestrian
Detection 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.
