Adaptive Cruise Control (ACC) with Low Speed Follow
Helps maintain a constant vehicle speed a nd a set following-interval behind a vehicle
detected ahead of yours and, if the detect ed vehicle comes to a stop, can decelerate
and stop your ve hicle, without yo u 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.1 Adaptive Cruise Control (ACC) with Low Speed Follow
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.
The radar sensor for ACC with Low Speed Follow is
shared with the collision mitigation braking system
TM
(CMBSTM).
2 Collision Mitigation Braking SystemTM
(CMBSTM) P. 453
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 weather conditions.
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.
When to use
■Vehicle speed for ACC wi th 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.
■Shift position for ACC with Low Speed Follow: In ( D or (S.
The radar sensor is in
the lower bumper.
Be careful not to have
the radar sensor cover

You can read about handling information for the
camera equipped with this system.
2 Front Sensor Camera P. 491
When the MAIN button is pressed, both ACC with
Low Speed Follow and the Lane Keeping Assist
System (LKAS) are either turned on or off.
ACC with Low Speed Follow may not work properly
under certain conditions.
2 ACC with Low Speed Follow Conditions
and Limitations P. 469
When not using ACC with Low Speed Follow: Turn
off adaptive cruise by pressing the MAIN button. This
also will turn off the Lane Keeping Assist System
(LKAS).
Do not use ACC with Low Speed Follow under the
following conditions:
•On roads with heavy traf fic or while driving in
continuous stop and go traffic.
•On roads with sharp turns.•On roads with steep downhill sections, as the set
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.

Driving
When driving at about 25 mph (40 km/h) or above: Take your foot off the
pedal and press the –/SET button when you reach the desired speed. The moment
you release the button, the set speed is fi xed, and ACC with Low Speed Follow begins.
When driving slower than about 25 mph (40 km/h): If the vehicle is moving
and the brake pedal is not depressed, pr essing the button fixes the set speed to
about 25 mph (40 km/h) regardless of current vehicle speed. If the vehicle is
stationary, you can set the vehicle speed even with the brake pedal depressed.
When ACC with Low Speed Follow starts
operating, the vehicle icon, interval bars and
set speed appear on the driver information
interface.
When you use ACC with Low Speed Follow,
Straight Driving Assist (a feature of the Electric
Power Steering system) is activated.
By enabling the steering system to
automatically compensate for natural steering
pull, Straight Driving Assist makes it easier for
you to keep your vehicle in a straight line.

■There is a vehicle ahead
ACC with Low Speed Follow monitors if a ve hicle ahead of you enters the ACC with
Low Speed Follow range. If a vehicle is detected doing so, the ACC with Low Speed
Follow system maintains or decelerates your vehicle’s set speed in order to keep the
vehicle’s set followi ng-interval from the vehicle ahead.
2To Set or Change Following-Interval P. 473
When a vehicle whose speed is slower than
your set speed is detected in front of you, your
vehicle starts to slow down.
■When in Operation1 When in Operation
If the vehicle ahead of you slows down abruptly, or if
another vehicle cuts in front of you, a beeper sounds,
a message appears on th e driver information
interface.
Depress the brake pedal, and keep an appropriate
interval from the vehicle ahead.

■There is no vehicle ahead
Your vehicle maintains the set speed without
having to keep your foot on the brake or
accelerator pedal.
If there previously was a vehicle detected
ahead that kept your vehicle from traveling at
the set speed, ACC with Low Speed Follow
accelerates your vehicle to the set speed, and
then maintains it.
■When you depress the accelerator pedal
You can temporarily increase the vehicle speed . In this case, there is no audible or
visual alert even if a vehicle is in the ACC with Low Speed Follow range.
ACC with Low Speed Follow stays on unle ss you cancel it. Once you release the
accelerator pedal, the system resume s an appropriate speed for keeping the
following-interval while a vehicle ahead is within the ACC with Low Speed Follow
range.
1 When in Operation
Even if the interval betw een your vehicle and the
vehicle detected ahead is short, ACC with Low Speed
Follow may start accelerati ng your vehicle under the
following circumstances:
•The vehicle ahead of you is going at almost the
same speed as, or faster than, your vehicle.
•A vehicle that cuts in front of you is going faster
than your vehicle, gradua lly increasing the interval
between the vehicles.
You can also set the system to beep when a vehicle in
front of you comes in and goes out of the ACC with
Low Speed Follow detect ing range. Change the ACC
Forward Vehicle Detect Beep setting.

Limitations
You may need to use the brake to maintain a safe
interval when using ACC with Low Speed Follow.
Additionally, ACC with Lo w Speed Follow may not
work properly under certain conditions.
