Driving
Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)*
Helps maintain a constant vehicle speed an d a set following-interval behind a vehicle
detected ahead of yours and, if the detect ed vehicle slows to a stop, decelerates and
stops your vehicle, without you having to keep your foot on the brake or the
accelerator.
When ACC with LSF slows your vehicle by applying the brakes, your vehicle's brake
lights will illuminate.1 Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)*
Important Reminder
As with any system, there are limits to ACC with LSF.
Use the brake pedal whenever necessary, and always
keep a safe distance between your vehicle and other
vehicles.
3WARNING
Improper use of ACC with LSF can lead to a
crash.
Use ACC with LSF only when driving on
expressways or freeways and in good
weather conditions.
3WARNING
ACC with LSF has limited braking
capability and may not stop your vehicle
in time to avoid a co llision with a vehicle
that quickly stops in front of you.
Always be prepared to apply the brake
pedal if the cond itions require.
When to use
■Vehicle speed for ACC with LSF: A vehicle is detected ahead within ACC with
LSF range – ACC with LSF operates at speeds up to 90 mph (145 km/h).
No vehicle is detected within ACC with LSF range – ACC with LSF operates at
the speed of 25 mph (40 km/h) or above.

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. u Take appropriate action to prevent a coll ision (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).
Models without Collision Mitigation Braking SystemTM (CMBSTM)
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. 103, 262

(LDW). 2 Lane Departure Warning Camera (LDW
Camera) P. 379
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 Acura replacement windshield. Making even
minor repairs within the ca mera’s field of vision or
installing an aftermarke t 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.

uuWhen Driving uVehicle Stability Assist (VSA ®), aka Electronic Stability Control (ESC), System
Continued
Driving
Vehicle Stability Assist (VSA ®), aka Electronic
Stability Control (ESC), System
Helps to stabilize the vehicl e during cornering if the vehicle turns more or less than
what was intended. It also assists in mainta ining traction on slippery surfaces. It does
so by regulating engine output 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 system. You will also see the
indicator blink.
■VSA ® Operation
1 Vehicle Stability Assist (VSA ®), aka Electronic Stability Control
(ESC), System
VSA ® may not function properly if tire type and size
are mixed. Make sure to use the same size and type
of tire, and the air pr essures as specified.
When the VSA ® system indicator comes on and stays
on while driving, there may 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 alwa ys 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.

Agile Handling Assist
Lightly brakes each of the front and rear wheels, as needed, when you turn the
steering wheel, and helps support the vehi cle’s stability and performance during
cornering.
Precision All-Wheel SteerTM (P-AWS ®) System
Monitors road conditions while you are dr iving. In response to current driving
conditions, the system automatically makes slight adjustment to the relative rear
wheel toe settings to help enhance vehicle control and stability.
1 Agile Handling Assist
The agile handling assist cannot 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.
1 Precision All-Wheel SteerTM (P-AWS® ) System
The Precision All-Wheel Steer
TM (P-AWS ®) System
cannot enhance vehicle cont rol and 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.
The toe setting of the rear wheels may get stuck in a
non-centered se tting if the system malfunctions
while driving. This can caus e the vehicle to pull to a
side even as you keep the steering wheel in the
center position. If this occurs, the system
automatically limits the vehicle speed to a maximum
of 50 mph (80 km/h). Reduce your speed and be
extra cautious, as handling may be difficult. Go to a
dealer immediately.

uuBraking uBrake System
404
Driving
Your vehicle is equipped with disc brakes at all four wheels. A vacuum power assist
helps reduce the effort needed on the brake pedal. The brake assist system increases
the stopping force when you depress th e brake pedal hard in an emergency
situation. The anti-lock brake system (ABS ) helps you retain steering control when
braking very hard.
2 Brake Assist System P. 408
2 Anti-lock Brake System (ABS) P. 407
■Foot Brake1Foot Brake
Check the brakes after driving through deep water,
or if there is a buildup of road surface water. If
necessary, dry the brakes by lightly depressing the
pedal several times.
If you hear a continuous me tallic friction sound when
applying the brakes, this is caused by the brake wear
indicator rubbing on the brake rotor and indicates
that the brake pads need to be replaced. Have the
vehicle checked by a deal er. If you hear only an
occasional squeak or squeal when you initially apply
the brake pedal, this may be normal and caused by
high frequency vibration of the brake pads against
the rotating brake disc.
Constantly using the brak e pedal while going down a
long hill builds up heat, which reduces the brake
effectiveness. Apply engine braking by taking your
foot off the accelerator pe dal and downshifting to a
lower gear.
Do not rest your foot on the brake pedal while
driving, as it will lightly apply the brakes and cause
them to lose effectiveness over time and reduce pad
life. It will also conf use drivers behind you.
Your vehicle is equipped with a hydraulic brake
booster that, under certain conditions, such as
braking at high altitudes, supplements the vacuum
power assist. When the hydraulic brake booster
activates, you may hear a motor sound and a slight
vibration in the pedal. This is normal.
