1. Pull the release lever in the trunk to release
the lock.
2. Fold the seat-back down.
■Folding Down the Rear Seats1Folding Down the Rear Seats
The rear seat-back(s
*) 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. 75
To lock a seat-back upright, push it backwards until it
locks.
When returning the 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.
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. 59
Make sure all items in the trunk or items
extending through the opening into the rear
seats are 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.

• Be sure items placed on the floor behind the front seats cannot roll under the
seats.
u They can interfere with the driver's ability to operate the pedals, the operation
of the seats, or the operation of the sensors under the seats.
• Everyone in the vehicle must fasten their seat belt.

Honda Sensing®
Honda Sensing® is a driver support system which employs the use of two distinctly
different kinds of sensors: a radar sensor located in the lower bumper and a front
sensor camera mounted to th e interior side of the windshield, behind the rearview
mirror.
Honda Sensing® has following functions.

Driving
Collision Mitigation Braking SystemTM (CMBSTM)
Can assist you when there is a possibility of your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The CMBSTM is designed to alert you when the
potential for a collision is determined, as well as to reduce your vehicle speed to help
minimize collision severity when a collision is deemed unavoidable.
1 Collision Mitigation Braking SystemTM (CMBSTM)
Important Safety Reminder
The CMBS
TM is designed to reduce the severity of an
unavoidable collision. It doe s not prevent collision nor
stop the vehicle automatically. It is still your
responsibility to operate the brake pedal and steering
wheel appropriately acco rding to the driving
conditions.
The CMBS
TM may not activate or may not detect a
vehicle in front of y our vehicle under certain
conditions:

camera equipped with this system. 2 Front Sensor Camera P. 491

■How the system works1How the system works
When the CMBS
TM activates, it may automatically
apply the brake. It will be canceled when your vehicle
stops or a potential coll ision is not determined.
The radar sensor is in
the lower bumper.
The camera is located
behind the rearview
mirror.
The system starts monitoring the roadway ah ead when your vehicle speed is about
3 mph (5 km/h) and there is a vehicle in front of you.
When to use
The CMBSTM activates when:●The speed difference between your vehicle and a vehicle or pedestrian detected
in front of you becomes about 3 mph (5 km/h) and over with a chance of a
collision.
●Your vehicle speed is about 62 mph (100 km/h) or less and the system determines
there is a chance of a collision with:
- Vehicles detected in front of you that ar e stationary, oncoming, or traveling in your
same direction.
- A pedestrian who is detected in front of you.
●Your vehicle speed is above 62 mph (100 km/h), and the system determines there
is a chance of a collision with a vehicle detected in front of you traveling in your
same direction.
