Road Departure Mitigation (RDM) System
Alerts and helps to assist you when the system detects a possibility of your vehicle
unintentionally crossing over detected lane markings and/or leaving the roadway
altogether.
The front camera behind the rearview mirror
monitors left and right lane markings (in white
or yellow). If your vehicl e is getting too close to
detected lane markings without a turn signal
activated, the system, in addition to a visual
alert, applies steering torque and alerts you
with rapid vibrations on the steering wheel, to
help you remain within the detected lane.
2 Customized Features P. 99, 316
As a visual alert, the Lane Departure message
appears on the multi-information display.
If the system determines that its steering input
is insufficient to keep your vehicle on the
roadway, it may apply braking.
u Braking is applied only when the lane
markings are solid continuous lines.
The system cancels assisting operations wh en you turn the steering wheel to avoid
crossing over detected lane markings.
If the system operates several times with out detecting driver response, the system
beeps to alert you.
■How the System Works
1 Road Departure Mitigation (RDM) System
Important Safety Reminder
Like all assistance systems, the RDM system has
limitations.
Over-reliance on the RDM system may result in a
collision. It is always your responsibility to keep the
vehicle within your driving lane.
The RDM system only alerts you when lane drift is
detected without a turn signal in use. The RDM
system may not detect all la ne markings or lane or
roadway departures; accu racy will vary based on
weather, speed and lane marker condition. It is
always your responsibilit y to safely operate the
vehicle and avoid collisions.
You can read about handling information for the
camera equipped with this system.

Driving
Front Sensor Camera
The camera, used in systems su ch as LKAS, RDM, ACC, and CMBSTM, 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
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.

•Always keep the radar sensor cover clean.•Never use chemical solvents or polishing powder
for cleaning the sensor cove r. Clean it with water
or a mild detergent.
•Do not put a sticker on th e radar sensor cover or

If you need the radar sensor to be repaired, or
removed, or the radar se nsor cover is strongly
impacted, turn off the system by using the CMBS

Cross Traffic Monitor*
Monitors the rear corner areas using the radar sensors when reversing, and alerts
you if a vehicle approaching from a rear corner is detected.
The system is convenient when you are backing out of a parking space.1Cross Traffic Monitor*
3CAUTION
Cross Traffic Monitor cannot detect all
approaching vehicles and may not detect
an approaching vehicle at all.
Failure to visually confirm that it is safe to
back up the vehicle before doing so may
result in a collision.
Do not solely rely on the system when
reversing; always also use your mirrors, and
look behind and to the sides of your vehicle
before reversing.

•The transmission is in (R.
• Your vehicle is moving at 3 mph (5 km/h) or
lower.
When a vehicle is detected approaching from a rear corner, Cross Traffic Monitor
alerts you with a buzzer and a displayed warning.
The system will not detect a vehicle that approaches from directly behind your
vehicle, nor will it provide alerts about a detected vehicle when it moves directly
behind your vehicle.
The system does not provide alerts for a vehicle that is moving away from your
vehicle, and it may alert for pedestri ans, bicycles, or stationary objects.
■How the System Works1Cross Traffic Monitor*
Cross traffic monitor may not detect or may delay
alerting an approach ing vehicle, or may alert without
an approaching vehicle under the following
conditions:
•An obstacle, such as a nother vehicle and a wall,
near your vehicle’s rear bumper, is blocking the
radar sensor’s scope.
•Your vehicle is moving at the speed of about 3 mph
(5 km/h) or higher.
•A vehicle is approaching at the speed other than
between about 6 mph (10 km/h) and 16 mph (25
km/h).
•The system picks up external interference such as
other radar sensors from an other vehicle or strong
radio wave transmitted fr om a facility nearby.
•Either corner of the rear bumper is covered with
snow, ice, mud or dirt.
•When there is bad weather.
•Your vehicle is on an incline.
•Your vehicle is tilted due to a heavy load in the rear.•Your vehicle is reversing towards a wall, a pole, a
vehicle, and so on.
The rear bumper or the sens ors have been improperly
repaired or the rear bum per has been deformed.
Have your vehicle checked by a dealer.
For proper operation, always keep the rear bumper
corner area clean.
Do not cover the rear bumper corner area with labels
or stickers of any kind.

uuChecking and Maintaining Tires uTire and Wheel Replacement
Maintenance
Tire and Wheel Replacement
Replace your tires with radials of the sa me size, load range, speed rating, and
maximum cold tire pressure ra ting (as shown on the tire’s sidewall). Using tires of a
different size or construction can cause ce rtain vehicle systems such as the ABS and
Vehicle Stability Assist
TM (VSA ®) system to work incorrectly.
It is best to replace all four tires at the same time. If that isn’t possible, replace the
front or rear tires in pairs.
Whenever you have a tire replaced or reset, make sure that the rubber valve stem is
replaced and that the TPMS sensor is trans ferred from the old valve stem to the new
one.
If you replace a wheel, make sure that the wheel’s specifications match those of the
original wheels.
1 Tire and Wheel Replacement
3WARNING
Installing improper tires on your vehicle can
affect handling and stability. This can cause
a crash in which you can be seriously hurt or
killed.
Always use the size and type of tires
recommended in this owner’s manual.
