Driving
The Traffic Sign Recognition system may not operate correctly, such as displaying a
sign that does not follow the actual regula tion for the roadway or does not exist at
all in the following cases.
u A speed limit sign may display at a higher or lower speed than the actual speed
limit.
• There is a supplementary sign with further information such as weather, time,
vehicle type, school zone, etc.
• Figures on the sign are hard to read (electric signs, numbers on the sign are
blurred, etc.).
• The sign is in the vicinity of the lane you are driving in , even though it is not for
the lane, such as a speed limit sign situated at an exit or an intersection between
the side road an d the main road.
• There are things that look similar to th e color or shape of the recognition object
(similar sign, electric sign, signboard, structure, etc.).
• A truck or another large vehicle with a sticker of the speed limit sign on the back

uuAcuraWatchTMuFront Sensor Camera
Continued
Driving
Front Sensor Camera
The camera, used in systems such as Lane Keeping Assist System (LKAS), Road
Departure Mitigation system, Adaptive Cruise Control (ACC) with Low Speed
Follow, Collision Mitigation Braking System
TM (CMBSTM), Traffic Sign Recognition
system, and Traffic Jam Assist 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 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
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 operate abnormally.
Scratches, nicks, and othe r damage to the windshield
within the camera’s fiel d of vision can cause the
system to operate abnormall y. 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 winds hield, 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.

with the airflow directed towards the camera.
•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 safe place, and make sure the
windshield is clean. Clean the windshield if it is
dirty. If the message doe s not disappear after
driven for a while, have your vehicle checked by a
dealer.

Driving
Your vehicle is equipped with disc brakes at all four wh eels. The brake assist system
increases the stopping force when you depress the brake pedal hard in an
emergency situation. The an ti-lock brake system (ABS) helps you retain steering
control when braking very hard.
2 Brake Assist System P. 493
2 Anti-lock Brake System (ABS) P. 492
■Brake squeal
To satisfy the performance under a wide range of driving conditions, a high
performance braking system is equipped on your vehicle. You may hear the brake
squeal under certain conditions, such as vehicle speed, deceleration, humidity, and
so on. This is not a malfunction.
■Foot Brake1 Foot Brake
Check the brakes after driving through deep water,
or if there is a buildup of road surface water. If
necessary, dry the brakes by lightly depressing the
pedal several times.
If you hear a continuous me tallic friction sound when
applying the brakes, this is caused by the brake wear
indicator rubbing on the brake rotor and indicates
that the brake pads need to be replaced. Have the
vehicle checked by a deal er. If you hear only an
occasional squeak or squeal when you initially apply
the brake pedal, this may be normal and caused by
high frequency vibration of the brake pads against
the rotating brake disc.
Constantly using the brake pedal while going down a
long hill builds up heat, which reduces the brake
effectiveness. Apply engine braking by taking your
foot off the accelerator pe dal and downshifting to a
lower gear.
Do not rest your foot on the brake pedal while
driving, as it will lightly apply the brakes and cause
them to lose effectiveness over time and reduce pad
life. It will also conf use drivers behind you.
