■Folding Down the Rear Seat
1Folding Down the Rear Seat
The rear seat-back can be folded down to
accommodate bulkier items in the trunk.
Never drive with the seat-back folded down and the
trunk lid open.
2 Exhaust Gas Hazard P. 64
To lock the seat-back upright, push it backwards until
it locks.
When returning a seat-back to its original position,
push it firmly back. Also, make sure all rear shoulder
belts are positioned in front of the seat-back, and the
center shoulder belt is re-positioned in the guide.
Make sure that the folded seat-back does not press
against the front passenger seat, as this can cause the
weight sensors in the front passenger seat to work
improperly. 2 Passenger Airbag Off Indicator P. 50
Also make sure all items in the trunk or items
extending through the opening into the rear
seat is properly secured. Loose items can fly
forward if you have to brake hard.
The front seat(s) must be far enough forward so they
do not interfere with the rear seats as they fold
down.

452Driving
The radar sensor monitors the distance between your vehicle and a vehicle ahead of
you. When the sensor detects a change in distance, the system compensates it by
accelerating or braking your vehicle in order to maintain the cruising speed you
previously set.■When in Operation
1When in Operation
If the vehicle ahead of you slows down abruptly, or if
another vehicle cuts in front of you, the beeper
sounds and a message appears on the multi-
information display to alert you.
Depress the brake pedal, and keep an appropriate
distance from the vehicle ahead.
Even if the distance between your vehicle and the
vehicle ahead is short, FCW may not alert you or ACC
may start accelerating your vehicle under the
following circumstances:•The vehicle ahead of you is going at almost the
same speed as, or faster than your vehicle.•A vehicle cuts in front of you is going faster than
your vehicle, gradually distancing.
If you do not want to hear a beep when the system
detects a vehicle, or when the vehicle goes out of
ACC range, you can change the pre-running detect
car beep setting. 2 Customized Features P. 97, 299

Driving
Forward Collision Warning (FCW)

Alerts you when it detects the possibility of your vehicle colliding with the vehicle in
front of yours.
If the system determines a collision is possible, it gives both visual and audible alerts,
including a heads-up warning th at flashes on the windshield.
u Take appropriate action to prevent a collision (apply the brakes, change lanes,
etc.).■How the system works
The system may give warnings of potential collisions when your vehicle speed is
above 10 mph (15 km/h).
1 Forward Collision Warning (FCW)
*
Important Safety Reminder
FCW cannot detect all objects ahead and may not
detect a given object; accuracy of the system will vary
based on weather, speed and other factors. FCW
does not include a braking function. It is always your
responsibility to safely operate the vehicle and avoid
collisions.
You can change the Forward Collision Warning
Distance setting or turn the system on and off.
2 Customized Features P. 97, 299
For the FCW system to work properly:•Always keep the radar sensor cover clean.•Never use chemical solvents or polishing
compounds to clean the sensor cover. Instead,
clean it with water and a mild detergent.•Do not put anything on the radar sensor cover.
See a dealer if the radar sensor gets damaged or
requires repair.

1Forward Collision Warning (FCW)
*
Never apply a film or attach any objects to the
windshield that could obstruct the FCW camera's
field of vision.
Scratches, nicks, and other damage to the windshield
within the FCW 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 Honda 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 FCW
camera is necessary for the system to operate
properly.Models with information display1How the system works
The heads-up warning uses a lens located at the front
end of the dashboard.
Do not cover the lens or spill any liquid on it.
