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

not allow it to cover the camera housing.

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.

uuChecking and Maintaining Tires uDOT Tire Quality Grading (U.S. Vehicles)
Continued
Maintenance
DOT Tire Quality Grading (U.S. Vehicles)The tires on your ve hicle meet all U.S. Federal Safety
Requirements. All tires are also graded for treadwear, traction,
and temperature performance according to Department of
Transportation (DOT) standards. The following explains these
gradings.
Quality grades can be found where applicable on the tire sidewall
between tread shoulder and maximum section width.
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a
specified government test course. For example, a tire graded 150
would wear one and one-half (1 1/2) times as well on the
government course as a tire graded 100. Th e relative performance
of tires depends upon the actual conditions of their use, however,
and may depart significantly from the norm due to variations in
driving habits, service practices and differences in road
characteristics and climate.■

All passenger car tires must conform
to Federal Safety Requirements in
addition to these grades.

469Maintenance
Climate Control System MaintenanceDust and Pollen FilterThe climate control system is equipped with a dust and pollen filter that collects
pollen, dust, and other debris in the air. The Maintenance Minder
TM messages will let
you know when to replace the filter.
We recommend that you replace the dust and pollen filter sooner when using your
vehicle in areas with high concentrations of dust.
1 Dust and Pollen Filter
If the airflow from the climate control system
deteriorates noticeably, and the windows fog up
easily, the filter may need to be replaced. Please
contact a dealer for replacement.

1. Immediately park the vehicle on level ground in a safe place.
2. If necessary, turn the hazard warning lights on.■What to do after parking the vehicle
1. Stop the engine and let it sit for about three minutes.
2. Open the hood and check the oil level.2 Oil Check P. 438
3.Start the engine and check the low oil pressure indicator.
u The indicator goes off: Start driving again.
u The indicator does not go off within 10 seconds: Stop the engine
and contact a dealer for repairs immediately.
If the Charging System Indicator Comes On
■Reasons for the indicator to come on
Comes on when the battery is not being charged.■What to do when the indicator comes on
Turn off the climate control system, rear defogger, and other electrical
systems, and immediately contact a dealer for repairs.
1 If the Low Oil Pressure Indicator Comes OnNOTICERunning the engine with low oil pressure can cause
serious mechanical damage almost immediately.1If the Charging System Indicator Comes On
If you need to stop temporarily, do not turn off the
engine. Restarting the engine may rapidly discharge
the battery.
