vehicle speed can be exceeded by coasting. In such
cases, ACC with Low Speed Follow will not apply
the brakes to maintain the set speed.
•On roads with toll collection facilities or other
objects between lanes of traffic, or in parking
areas, or faci lities with driv e through access.

• A vehicle suddenly crosses in front of you.
• The interval between your vehicle and the vehicle ahead of you is too short.
• A vehicle cuts in front of you at a slow speed, and it brakes suddenly.
• When you accelerate rapidly and approach the vehicle ahead of you at high
speed.
• The vehicle ahead of you is a motorcycle, bicycle, mobility scooter, or other small
vehicle.
• When there are animals in front of your vehicle.
• When you drive on a curved or winding or undulating road that makes it difficult
for the sensor to properly detect a vehicle in front of you.

■Automatic ca ncellation
The beeper sounds and a message appears on the driver information interface when
ACC with Low Speed Follow is automatically canceled. Any of these conditions may
cause the ACC with Low Speed Fo llow to automatically cancel:
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor in the lower bumper gets dirty.
• The vehicle ahead of yo u cannot be detected.
• An abnormal tire condition is de tected, or the tires are skidding.
• Driving on a mountainous road, or driving off road for extended periods.
• Abrupt steering wheel movement.
• When the ABS, VSA ® or CMBS
TM is activated.
• When the ABS or VSA ® system indicator comes on.
• When the vehicle is stopped on a very steep slope.
• When you manually apply the parking brake.
• When the detected vehicle within the AC C with Low Speed Follow range is too
close to your vehicle.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
• When the Maximum Load Limit is exceeded.
• When passing through an enclosed space, such as tunnel.
The ACC with Low Speed Follow automatic cancellation can be also triggered by the
following causes. In these cases, the parking brake will be automatically applied.
• The driver’s seat belt is unfastened when the vehicle is stationary.
• The vehicle stops for more than 10 minutes.
• The engine is turned off.
1Automatic cancellation
Even though ACC with Low Speed Follow has been
automatically canceled, you can still resume the prior
set speed. Wait until the condition that caused ACC
with Low Speed Follow to cancel improves, then
press the –/SET button.

Adaptive Cruise Control (ACC)*
Helps maintain a constant vehicle speed an d a set following-interval behind a vehicle
detected ahead of yours, without you havi ng to keep your foot on the brake or the
accelerator.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 interval betw een your vehicle and other vehicles.
The radar sensor for ACC is shared with the collision
mitigation braking system
TM (CMBSTM).
2 Collision Mitigation Braking SystemTM
(CMBSTM) P. 470
3WARNING
Improper use of ACC can lead to a crash.
Use ACC only when driving on
expressways or freeways and in good
weather conditions.
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 c ontrol: Desired speed in a range above
roughly 25 mph (40 km/h) ~.
■Gear position for ACC: In ( 2 or higher position. The radar sensor is in the
lower bumper.Be careful
not to have the radar
sensor cover strongly
impacted.
The camera is
located behind the
rearview mirror.
