Driving
Vehicle Stability AssistTM (VSA ®), aka Electronic
Stability Control (ESC), System
VSA ® helps stabilize the vehicle during cornering if the vehicle turns more or less
than what was intended. It also assists in maintaining traction on slippery surfaces.
It does so by regulating engine ou tput and selectively applying the brakes.
When VSA ® activates, you may notice that the
engine does not respond to the accelerator.
You may also notice some noise from the
hydraulic brake system. You will also see the
indicator blink.
■VSA ® Operation
1 Vehicle Stability AssistTM (VSA® ), aka Electronic Stability Control
(ESC), System
The VSA ® may not function properl y if tire type and
size are mixed. Make sure to use the same size and
type of tire, and the air pressures as specified.
When the VSA ® system indicator comes on and stays
on while driving, there ma y be a problem with the
system. While this may not interfere with normal
driving, have your vehi cle checked by a dealer
immediately.
VSA ® cannot enhance stability in all driving situations
and does not control the entire braking system. You
still need to drive and corner at speeds appropriate
for the conditions and always leave a sufficient
margin of safety.
The main function of the VSA ® system is generally
known as Electronic Stability Control (ESC). The
system also includes a traction control function.
The Vehicle Stability Assist
TM (VSA ®) system, Vehicle
Stability AssistTM (VSA ®) OFF, adaptive cruise control
(ACC) with Low Speed Follow, safety support and
low tire pressure/TPMS indicators may come on in
amber along with a message in the driver information
interface when you set the power mode to ON after
reconnecting the battery.
Drive a short distance at more than 12 mph (20 km/h).
Each indicator should go off. If any do not, have your
vehicle checked by a dealer.

Agile Handling Assist
Lightly brakes the front wheels, as needed , when you turn the steering wheel, and
helps support the vehicle’s stability and performance during cornering.1 Agile Handling Assist
The agile handling assist ca nnot enhance stability in
all driving situations. You still need to drive and
corner at speeds appropriate for the conditions and
always leave a sufficient margin of safety.
When the VSA ® system indicator comes on and stays
on while driving, the agil e handling assist does not
activate.
You may hear a sound coming from the engine
compartment while the agile handling assist is
activated. This is normal.

uuHonda Sensing ®u Collision Mitigation Braking SystemTM (CMBSTM)
Driving
Collision Mitigati on 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.
■How the system works
1 Collision Mitigation Braking SystemTM (CMBSTM)
Important Safety Reminder
The CMBS
TM is designed to reduce the severity of an
unavoidable collision. It does not prevent collisions
nor stop the vehicle automati cally. It is still your
responsibility to operate th e 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: 2 CMBS
TM Conditions and Limitations P. 462
For directions on the prop er handling of the radar
sensor, refer to the following page. 2 Radar Sensor P. 508
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 506
When the CMBS
TM activates, it may automatically
apply the brake. It will be canceled when your vehicle
stops or a potential collision is not determined.
The radar sensor is at the
lower part of the front
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.
