Before DrivingDriving PreparationCheck the following items before you start driving.
•Make sure there are no obstructions on the windows, door mirrors, exterior
lights, or other parts of the vehicle.
u Remove any frost, snow, or ice.
u Remove any snow on the roof, as this can slip down and obstruct your field of
vision while driving. If frozen solid, remove ice once it has softened.
u When removing ice from around the wheels, be sure not to damage the wheel
or wheel components.
• Make sure the hood is securely closed.
u If the hood opens while driving, your front view will be blocked.
• Make sure the tires are in good condition.
u Check air pressures, and check for damage and excessive wear.
2 Checking and Maintaining Tires P. 439
•Make sure there are no people or objects behind or around the vehicle.
u There are blind spots from the inside.■
Exterior Checks
1Exterior ChecksNOTICEWhen doors are frozen shut, use warm water around
the door edges to melt any ice. Do not try to force
them open, as this can damage the rubber trim
around the doors. When done, wipe dry to avoid
further freezing.
Do not pour warm water into the key cylinder.
You will be unable to insert the key if the water
freezes in the hole.
Heat from the engine and exhaust can ignite
flammable materials left under the hood, causing a
fire. If you’ve parked your vehicle for an extended
period, inspect and remove any debris that may have
collected, such as dried grass and leaves that have
fallen or have been carried in for use as a nest by a
small animal.
Also check under the hood for leftover flammable
materials after you or someone else has performed
maintenance on your vehicle.

uuWhen Driving uForward Collision Warning (FCW)
*
Driving
■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.
1 Automatic 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 /CAN
NOT OPERATE 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.
Beep The camera is located
behind the rearview mirror.
The beeper sounds and the
BRAKE message
appears in the multi-information display until
a possible collision is avoided.

•Shadows of adjacent object s are parallel to lane
markings.•The windshield is dirty.•Where the roadway has crossing or other lines
(e.g., such as at an intersection).
1 LKAS 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.
