(P.
3.Press the ENGINE START/STOP button
without depressing the accelerator pedal.
The engine will crank until it starts.
1Starting the Engine
Keep your foot firmly on the brake pedal when
starting the engine.
The engine is harder to start in cold weather and in
thinner air found at altitudes above 8,000 feet (2,400
meters).When starting the engine in cold weather, turn off all
electrical accessories such as the lights, climate control
system, and rear defogger in order to reduce battery drain.If you live in a region where winter is extremely cold,
an engine block heater will improve starting and
warming of the engine. If temperatures consistently
below -22°F (-30°C) are expected, the coolant
mixture should be changed to a higher concentration
to prevent freezing. Consult a dealer for details.
If the exhaust system sounds abnormal or you can
smell exhaust gas inside the vehicle, have your vehicle
checked by a dealer. There may be a problem with
the engine or exhaust system.
Bring the keyless access remote close to the ENGINE
START/STOP button if the battery in the keyless
access remote is weak.
2If the Keyless Access Remote Battery is
Weak P. 458
The engine may not start if the keyless access remote
is subjected to strong radio waves.
Do not hold the ENGINE START/STOP button to
start the engine.
If the engine does not start, wait at least 10 seconds
before trying again.

uuWhen DrivinguForward Collision Warning (FCW)
*
348Driving
■Automatic shutoff
FCW may automatically shut itself off and the FCW indicator comes and stays on
when:
•The temperature inside the system is high.
•The windshield is blocked by dirt, mud, leaves, wet snow, etc.
Once the conditions that caused FCW to shut off improve or are addressed (e.g.,
cleaning), the system comes back on.
1Automatic shutoff
To help reduce the likelihood that high interior
temperatures will cause the camera 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 the camera.
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 FCW camera.

The camera is located behind the rearview
mirror.
Press the LDW button to turn the system on
and off.
uThe indicator in the button comes on
when the system is on.
■LDW Camera
1LDW Camera
Never apply a film or attach any objects to the
windshield that could obstruct the LDW camera’s
field of vision.
Scratches, nicks, and other damage to the windshield
within the LDW 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 within 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 LDW
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.
To help reduce the likelihood that high interior
temperatures will cause the camera system to shut off,
when parking, find a shady area or face the front of the
vehicle away from the sun. Also, do not use a reflective

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 within 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.

uuChecking and Maintaining TiresuDOT Tire Quality Grading (U.S. Vehicles)
Maintenance
DOT Tire Quality Grading (U.S. Vehicles)The tires on your vehicle 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. The 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.■Uniform Tire Quality Grading■Treadwear
1Uniform Tire Quality GradingFor example:
Treadwear 200
Traction AA
Temperature A
All passenger car tires must conform
to Federal Safety Requirements in
addition to these grades.

431Maintenance
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.
1Dust 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.
