uuHonda Sensing®uAdaptive Cruise Control (ACC) with Low Speed Follow
Adaptive Cruise Control (ACC) with Low Speed Follow
Helps maintain a constant vehicle speed and a set following-interval behind a vehicle
detected ahead of yours and, if the detected vehicle comes to a stop, can decelerate
and stop your vehicle, without you having to keep your foot on the brake or the
accelerator.
When ACC with Low Speed Follow slows your vehicle by applying the brakes, your
vehicle’s brake lights will illuminate.
1Adaptive Cruise Control (ACC) with Low Speed Follow
3WARNING
Improper use of ACC with Low Speed
Follow can lead to a crash.
Use ACC with Low Speed Follow only when
driving on expressways or freeways and in
good road and weather conditions.
When to use
A front sensor
camera is
located behind
the rearview
mirror.
3WARNING
ACC with Low Speed Follow has limited
braking capability and may not stop your
vehicle in time to avoid a collision with a
vehicle that quickly stops in front of you.
Always be prepared to apply the brake
pedal if the conditions require.
The radar sensor is behind
the Honda emblem on the
front grille.
Important Reminder
As with any system, there are limits to ACC with Low
Speed Follow. Use the brake pedal whenever
necessary, and always keep a safe interval between
your vehicle and other vehicles.
■ Vehicle speed for ACC with Low Speed Follow: A vehicle is detected ahead
within ACC with Low Speed Follow range – ACC with Low Speed Follow
operates at speeds up to 90 mph (145 km/h).
No vehicle is detected within ACC with Low Speed Follow range – ACC with
Low Speed Follow operates at the speed of 25 mph (40 km/h) or above.

and Limitations P. 503
When not using ACC with Low Speed Follow: Turn
off adaptive cruise by pressing the
button.
Do not use ACC with Low Speed Follow under the
following conditions:
• On roads with frequent lane-change or continuous
stop and go traffic, ACC with Low Speed Follow
cannot keep an appropriate distance between your
vehicle and the vehicle ahead of you.
• On roads with sharp turns.
• On roads with toll collection facilities or other
objects between lanes of traffic, or in parking
areas, or facilities with drive through access.
• On roads with bad weather (rain, fog, snow, etc.),
ACC with Low Speed Follow may not detect the
distance between your vehicle and the vehicle
ahead of you properly.
• On roads with slippery or icy surfaces. The wheels
may spin out and your vehicle may lose the control
on the condition.
• On roads with steep uphill or steep downhill slopes.
• On roads with undulating slopes.

line.
When driving slower than about 25 mph (40 km/h): If the vehicle is moving
and the brake pedal is not depressed, pressing the switch fixes the set speed to
about 25 mph (40 km/h) regardless of current vehicle speed. If the vehicle is
