Helps maintain a constant vehicle speed and a set following distance behind a
vehicle detected ahead of yours and, if the detected vehicle comes to a stop,
decelerates and stops your vehicle, without you having to keep your foot on the
brake or the accelerator.
1Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)

Important Safety ReminderAs with any system, there are limits to ACC with LSF.
Inappropriate use of ACC with LSF can result in a serious
accident. Use the brake pedal whenever necessary, and always
keep a safe distance between your vehicle and other vehicles.The radar sensor for ACC with LSF is shared with the
collision mitigation braking system
TM (CMBS
TM).

WARNING
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.

WARNING
Exiting a vehicle that has been stopped
while the ACC with LSF system is
operating can result in the vehicle
moving without operator control.
A vehicle that moves without operator
control can cause a crash, resulting in
serious injury or death.
■Vehicle speed for ACC with LSF: A vehicle is
detected ahead within ACC with LSF range –
ACC with LSF operates at any vehicle speed.
No vehicle is detected within ACC with LSF
range – ACC with LSF operates at the speed of
25 mph (40km/h) or above.■Shift positions for ACC with LSF: In

When driving at 25 mph (40 km/h) or above: Take your foot off the pedal and
press down the RES/+/SET/– switch when you reach the desired speed. The moment
you release the switch, the set speed is fixed, and ACC with LSF begins.
When driving at slower than 25 mph (40 km/h): You can set the vehicle speed
only when there is a vehicle detected ahead of you. If the vehicle is moving and the
brake pedal is not depressed, pressing the switch fixes the set speed to 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 LSF starts operating, the
vehicle icon, distance bars and set speed
appear on the MID. ■To Set the Vehicle Speed

When the MAIN button is pressed, ACC with LSF and
Lane Keeping Assist System (LKAS) are both turned on
or off.
Do not use ACC with LSF under these conditions:•In poor visibility (e.g., bad weather, such as rain,
fog, and snow).•When you must slow down and speed up
repeatedly.•On winding roads.•When you enter a toll gate, interchange, service
area, parking area, etc. In these areas, there is no
vehicle ahead of you, but ACC with LSF would still
try to accelerate to your set speed.•On a slippery road (for example a road covered
with ice or snow).•When a spare tire
* is installed.
•When going down a steep hill where the engine
braking does not work sufficiently.
When not using ACC with LSF: Turn off adaptive
cruise by pressing the MAIN button. This also will
turn off the Lane Keeping Assist System (LKAS).

■There is a vehicle ahead
ACC with LSF monitors if a vehicle ahead of you enters the ACC with LSF range. If it
does, the ACC with LSF system maintains or decelerates your vehicle’s set speed in
order to keep the vehicle’s set following distance from the vehicle ahead.2To Set or Change Following Distance P. 342
When a vehicle whose speed is slower than
your set speed comes in front of you, your
vehicle starts to slow down.
■When in Operation
1When in Operation
If the vehicle ahead of you slows down abruptly, or if
another vehicle cuts in front of you, the beeper
sounds and a message appears on the multi-
information display to alert you.
Depress the brake pedal, and keep an appropriate
distance from the vehicle ahead.
Even if the distance between your vehicle and the
vehicle ahead is short, ACC with LSF may start
accelerating 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, gradually increasing the distance
between the vehicles.
If you do not want to hear a beep when the system
detects a vehicle, or when the vehicle goes out of the
ACC with LSF range, you can change the pre-running
detect car beep setting.

■There is no vehicle ahead
When driving at 22 mph (35 km/h) or above:
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 travelling at
the set speed, ACC with LSF accelerates your
vehicle to the set speed, and then maintains it.
When driving under 22 mph (35 km/h) and no
vehicle is detected ahead: ACC with LSF
automatically cancels. The beeper sounds once.
■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 LSF range.
ACC with LSF stays on unless you cancel it. Once you release the accelerator pedal,
the system resumes the set speed.■A vehicle ahead is within ACC range and stops
Your vehicle also stops, automatically. The
Stopped message appears on the multi-
information display.
When the vehicle ahead of you starts again,
the vehicle icon on the MID blinks. If you press
the RES/+/SET/– switch up or down, or
depress the accelerator pedal, ACC with LSF
operates again within the prior set speed.A vehicle icon with dotted-line
contour appears on the MID
1When in Operation
Limitations
Use the brake pedal to maintain a safe distance with
other vehicles in the following cases. ACC with LSF
may not work properly when:•A vehicle ahead of you is parked when your vehicle
is moving.•Motorcycles or other small vehicles are ahead of
you.•A vehicle cuts in front of you at a short distance.
ACC with LSF may momentarily apply brakes or
sound a beep if there is a vehicle, or even a building,
next to you if:•You make a sudden turn or drive on a narrow road.•You abruptly move the steering wheel.•You are in an unusual position within your lane.
When your vehicle stops automatically because a
vehicle detected ahead of you has stopped, the
distance between the two vehicles will vary based on
the ACC with LSF distance setting, as follows:
Short: 11.5 ft (3.5 m)
Middle: 14.1 ft (4.3 m)
Long, Extra Long: 16.4 ft (5.0 m)
