■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

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)

7.Select a nearby, lightly traveled major highway where you can maintain a speed
of 50 to 60 mph (80 to 97 km/h) for at least 20 minutes. Drive on the highway in (D. Do not use cruise control. When traffic allows, drive for 90 seconds without
moving the accelerator pedal. (Vehicle speed may vary slightly; this is okay.) If you
cannot do this for a continuous 90 seconds because of traffic conditions, drive for
at least 30 seconds, then repeat it two more times (for a total of 90 seconds).
