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 upri ght, push it backwards until
it locks.
When returning a seat-back to its original position,
push it firmly back. Also, m ake 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 se at, as this can cause the

uuWhen Driving uAdaptive Cruise Control (ACC)*
Driving
Adaptive Cruise Control (ACC)*
Helps maintain a constant vehicle speed and a set following distance behind a
vehicle detected ahead of yours, without you having to keep your foot on the brake
or the accelerator.1 Adaptive Cruise Control (ACC)*
Important Reminder
As with any system, there are limits to ACC. Use the
brake pedal whenever necessary, and always keep a
safe distance between your vehicle and other
vehicles.
The radar sensor for ACC is shared with FCW
(Forward Collision Warning). 2 Forward Collision Warning (FCW)
* P. 456
3WARNING
Improper use of ACC can lead to a crash.
Use ACC only when traveling on open
highways in good weather.
3WARNING
ACC has limited braking capability.
When your vehicle speed drops below
22 mph, ACC will au tomatically cancel
and no longer will apply your vehicle's
brakes.
Always be prepared to apply the brake
pedal when conditions require.
When to use
■Vehicle speed for adaptive cruise control:
Desired speed in a range above roughly 25
mph (40 km/h) ~
■Shift positions for adaptive cruise control:
In ( D or (S
The radar sensor is inside the front
grille on the right side.
How to use
■Press the MAIN button on
the steering wheel. ACC is on in the multi-
information display.
Adaptive cruise control is
ready to use.
* Not available on all models

uuWhen Driving uAdaptive Cruise Control (ACC)*
450
Driving
The radar sensor monitors the distance be tween your vehicle and a vehicle ahead of
you. When the sensor detects a change in distance, the system responds it by
accelerating or braking your vehicle in orde r to maintain the set speed and following
distance as necessary.
■When in Operation1 When 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 to brake.
Depress the brake pedal, and keep an appropriate
distance from the vehicle ahead.
Even if the distance betw een 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 fast er than your vehicle.
•A vehicle cuts in front of you is going faster than
your vehicle, gradually di stancing itself from you.
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, 298
Beep■When ACC detects a
vehicle within ACC range:■When the vehicle goes
out of ACC range:
The beeper sounds once and
the vehicle icon appears on the
multi-information display. The beeper sounds once

u ACC Off appears on the multi-
information display.
• Depress the brake pedal.
■Automatic cancellation
The beeper sounds and a me ssage appears on the multi-information display when
ACC is automatically canceled. Any of these conditions may cause the ACC
cancellation:
• Your vehicle speed slows down to 22 mph (35 km/h) and below.
• Bad weather (rain, fog, snow, etc.).
• When the radar sensor inside the front grille gets dirty.
• The vehicle ahead of you cannot be detected.
• An abnormal tire condition is detected, or the tires are skidding.
• Driving on a mountainous road, or driving off road for extended periods.
• Abrupt steering wheel movement.
• When the ABS or VSA is activated.
• When the ABS or VSA indicator comes on.

uuWhen Driving uForward Collision Warning (FCW)*
Driving
Forward Collision Warning (FCW)*
Alerts you when it determines that there is a possibility that your vehicle may collide
with a vehicle detected 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 col lision (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 ob jects ahead and may not
detect a given object; accura cy of the system will vary
based on weather, speed and other factors. FCW
does not include a braking func tion. It is always your
responsibility to sa fely 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, 298
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.
The camera is shared with Lane Departure Warning
(LDW). 2 LDW Camera P. 461

Driving
1Forward Collision Warning (FCW)*
Never apply a film or attach any objects to the
windshield that could obs truct the FCW camera's
field of vision.
Scratches, nicks, and othe r damage to the windshield
within the FCW camera's fi eld of vision can cause the
system to operate abnormall y. If this occurs, we
recommend that you replac e the windshield with a
genuine Honda replacem ent windshield. Making
even minor repairs within th e camera's field of vision
or installing an aftermarket replacement windshield
may also cause the system to operate abnormally.
After replacing the winds hield, have a dealer
recalibrate the camera. Prop er calibration of the FCW
camera is necessary for the system to operate
properly.
