Quick Reference Guide
AcuraWatchTM *
AcuraWatchTM is a driver support system
which employs the use of two distinctly
different kinds of sensors, a radar sensor
located in the front grille and a front sensor
camera mounted to the interior side of the
windshield, behind the rear view mirror.
The camera is located
behind the rearview
mirror.
Front Sensor
Camera
Radar Sensor
The radar sensor is
inside the front grille.
Adaptive Cruise Control
(ACC)
* (P286)
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.
Lane Keeping Assist
System (LKAS)
* (P303)
Provides steering input to help keep the
vehicle in the middle of a detected lane and
provides audible and visual alerts if the
vehicle is detected drifting out of its lane.
Collision Mitigation
Braking System
TM
(CMBS
TM)* (P324)
Can assist you when there is a possibility of
your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The
CMBS
TM is designed to alert you when a
potential collision is determined, as well as
to reduce your vehicle speed to help
minimize collision severity when a collision is
deemed unavoidable.

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.
When ACC slows your vehicle by applying the brakes, your vehicle’s brake lights will
illuminate.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.
3WARNING
Improper use of ACC can lead to a crash.
Use ACC only when travelling on open
highways in good weather.
3WARNING
ACC has limited braking capability.
When your vehicle speed drops below
22 mph (35 km/h), ACC will
automatically 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 co ntrol: Desired speed in a range above
roughly 25 mph (40 km/h) ~
The camera is located
behind the rearview mirror.
■Shift positions for adaptive cruise control: In (
D or (S
The radar sensor is in the front
grille.

• Abrupt steering wheel movement.
• When the ABS, VSA ® is activated.
• When the ABS or VSA ® system indicator comes on.
• When you manually apply the parking brake.
• When the detected vehicle within the ACC range is too close to your vehicle.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
■To Cancel1 To Cancel
Resuming the prior set speed: After you have
canceled adaptive cruise c ontrol, you can resume the
prior set speed while it is still displayed. Press the
RES/ACCEL button when driving at a speed of at
least 25 mph (40 km/h) or more.
You cannot set or resume wh en vehicle speed is less
than 25 mph (40 km/h).
The set speed cannot be set or resumed when ACC
has been turned off using the MAIN button. Press
the MAIN button to activate the system, then set the
desired speed.
1 Automatic cancellation
Even though adaptive crui se control has been
automatically canceled, you can still resume the prior
