When the System can be Used
1Lane Keeping Assist System (LKAS)
*
•Shadows of adjacent objects are parallel to lane
markings.•The windshield is dirty.•Where the roadway has crossing or other lines
(e.g., such as at an intersection).
1LKAS camera
Never apply a film or attach any objects to the
windshield that could obstruct the LKAS camera’s
field of vision.
Scratches, nicks, and other damage to the windshield
within the LKAS 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 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 LKAS
camera is necessary for the system to operate properly.
If the Can Not Operate: Camera Too 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 LKAS camera.
1 When the System can be Used
If the vehicle drifts toward either left or right lane line
due to the system applying torque, turn off the LKAS
and have your vehicle checked by a dealer.

You can change the setting for BSI.
2 Customizable Features P. 107
Turn the system off when towing a trailer.
The system may not work properly for the following
reasons:•The added mass tilts the vehicle and changes the
radar coverage.•The trailer itself can be detected by the radar
sensors, causing the BSI alert indicators to come on.
BSI may be adversely affected when:•Objects (guard rails, poles, trees, etc,.) are
detected.•An object that does not reflect radio waves well,
such as a motorcycle, is in the alert zone.•Driving on a curved road.•A vehicle is moving from a far lane to the adjacent
lane.•The system picks up external electrical interference.•The rear bumper or the sensors have been improperly
repaired or the rear bumper has been deformed.•The orientation of the sensors has been changed.•In bad weather (Heavy rain, snow, and fog).
For proper BSI use:•Always keep the rear bumper corner area clean.•Do not cover the rear bumper corner area with
labels or stickers of any kind. •Take your vehicle to a dealer if you need the rear
bumper corner area or the radar sensors to be repaired,
or the rear bumper corner area is strongly impacted.

no more than 31 mph (50 km/h) from your
vehicle.●You pass a vehicle with a speed difference
of no more than 12 mph (20 km/h).

Maintenance
Safety When Performing MaintenanceSome of the most important safety precautions are given here.
However, we cannot warn you of every conc eivable hazard that can arise in
performing maintenance. Only you can decide whether or not you should perform
a given task.
• To reduce the possibility of fire or explosion, keep cigarettes, sparks, and flames
away from the battery and all fuel related parts.
• Never leave rags, towels, or other flammable objects under the hood.
u Heat from the engine and exhaust can ignite them causing a fire.
• To clean parts, use a commercially available degreaser or parts cleaner, not
gasoline.
• Wear eye protection and protective clothing when working with the battery or
compressed air.
• Engine exhaust contains carbon monoxide, which is poisonous and can kill you.
u Only operate the engine if there is sufficient ventilation.
• The vehicle must be in a stationary condition.
u Make sure your vehicle is parked on level ground, the parking brake is set, and
the engine is off.
• Be aware that hot parts can burn you.
u Make sure to let the engine and exhaust system cool thoroughly before
touching vehicle parts.
• Be aware that moving parts can injure you.
u Do not start the engine unless instructed, and keep your hands and limbs away
from moving parts.■

Maintenance Service Items
1Maintenance Service Items•Independent of the Maintenance Minder
information, replace the brake fluid every 3 years.•Inspect idle speed every 160,000 miles (256,000
km).•Adjust the valves during services A, B, 1, 2, or 3 if
they are noisy.
Driving in mountainous areas at very low vehicle
speeds or trailer towing results in higher level of
mechanical (Shear) stress to fluid. This requires
differential fluid changes more frequently than
recommended by the Maintenance Minder. If you
regularly drive your vehicle under these conditions,
have the differential fluid changed at 7,500 miles
(12,000km), then every 15,000 miles (24,000 km).
