uuWhen Driving uFront Sensor Camera
Driving
Front Sensor Camera
The camera, used in systems such as LKAS , RDM, ACC with LSF, Traffic Jam Assist,
and CMBSTM, 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
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 re flective sun shade, do
not allow it to cover the camera housing.
Covering the camera can concentrate heat on
it.
■Camera Location and Handling Tips
1 Front Sensor Camera
Never apply a film or attach any objects to the
windshield, the hood, or th e front grille that could
obstruct the camera’s fiel d of vision and cause the
system to oper ate abnormally.
Scratches, nicks, and othe r damage to the windshield
within the camera’s fiel d of vision can cause the
system to operate abnormally. If this occurs, we
recommend that you replac e the windshield with a
genuine Acura replacement windshield. Making even
minor repairs within the ca mera’s field of vision or
installing an aftermarke t replacement windshield
may also cause the system to operate abnormally.
After replacing the windshield, have a dealer
recalibrate the camera. Pr oper 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.

•Start driving the vehicle to lower the windshield
temperature, which cool s down the area around
the camera.
If the Some Driver Assist Systems Cannot
Operate: Clean Front Windshield message
appears:
•Park your vehicle in a sa fe place, and clean the
windshield. If the message does not disappear after
you have cleaned the winds hield and driven for a

Driving
Adaptive Cruise Control (ACC) with Low Speed
Follow (LSF)
Helps maintain a constant vehicle speed an d a set following-interval behind a vehicle
detected ahead of yours and, if the detected vehicle comes to a stop, decelerates
and stop your vehicle, without you having to keep your foot on the brake or the
accelerator.
When ACC with LSF slows your vehicle by applying the brakes, your vehicle's brake
lights will illuminate.
1 Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)
Important Reminder
As with any system, there are limits to ACC with LSF.
Use the brake pedal whenever necessary, and always
keep a safe interval betw een your vehicle and other
vehicles.
3WARNING
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.
3WARNING
ACC with LSF has limited braking
capability and may not stop your vehicle
in time to avoid a co llision with a vehicle
that quickly stops in front of you.
Always be prepared to apply the brake
pedal if the cond itions require.
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 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.

•You are entering a toll boot h, interchange, service
area, or parking area.
uIf the vehicle ahead disappe ars from the travel path
of your vehicle, your vehi cle may suddenly accelerate
to resume the set speed.
•You are driving in bad we ather (rain, fog, snow,
etc.).
uThe system may not be able to correctly determine
the distance between yo ur vehicle and the one

When driving at about 25 mph (40 km/h) or above: Take your foot off the pedal
and press down the RES/+/SET/– switch when you reach the desired speed. The
moment you release the switch, the set sp eed is fixed, and ACC with LSF begins.
When driving at slower than about 25 mph (40 km/h): If the vehicle is moving
and the brake pedal is not depressed, pres sing the switch fixes the set speed to
about 25 mph (40 km/h) regardless of current vehicle speed. If the vehicle is
stationary, you can set the vehicle speed even with the brake pedal depressed. When ACC with LSF starts operating, the
vehicle icon, interval bars and set speed
appear on the multi-information display.

Driving
■There is a vehicle ahead
ACC with LSF monitors if a vehicle ahead of you enters the ACC with LSF range. If a
vehicle is detected doing so, the ACC with LSF system maintains or decelerates your
vehicle’s set speed in order to keep the ve hicle’s set following-interval from the
vehicle ahead.
2 To Set or Change Following-Interval P. 412
When a vehicle whose speed is slower than your set speed is detected in front of
you, your vehicle starts to slow down.
■When in Operation1 When in Operation
If the vehicle detected ahead of you slows down
abruptly, or if another vehi cle is detected cutting in
front of you, the beeper sounds, a message appears
on the multi-information di splay, and the head-up
warning come on.
Depress the brake pedal, and keep an appropriate
interval from the vehicle ahead.
Even if the interval betw een your vehicle and the
vehicle detected ahead is short, ACC with LSF may
start accelerating your ve hicle 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, gradua lly increasing the interval
between the vehicles.
You can also set the system to beep when a vehicle in
front of you comes in an d goes out of the ACC with
LSF 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 with LSF accelerates your
vehicle to the set speed, and then maintains it.
■When you depress the accelerator pedal
You can temporarily increase th e vehicle speed. In this case, there is no audible or
visual alert even if a vehicle is in the ACC with LSF range.
ACC with LSF 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 with LSF range.
■A vehicle detected ahead is within AC C with LSF range and slows to a stop
Your vehicle also stop s, automatically. The
Stopped message appears on the multi-
information display.
When the vehicle ahead of you starts again,
the vehicle icon on the multi-information
display blinks. If you press the RES/+/SET/–
switch up or down, or depress the accelerator
pedal, ACC with LSF operates again within the
prior set speed.
