Driving
■There is a vehicle ahead
ACC with LSF monitors if a vehicle ahead of you enters the ACC with LSF range. If a
vehicle is detected doing so, 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.
2 To Set or Change Following-distance P. 374
When a vehicle whose speed is slower than
yo ur se t spe e d com e s i n or c ut s in fr o nt of y ou
and is detected by the radar and the camera,
your vehicle starts to slow down.
■When in Operation1 When in Operation
If the vehicle detected ahead of you slows down
abruptly, or if a nother vehicle is de tected cutting in
front of you, the beep er sounds and a message
appears on the MID.
Depress the brake pedal, and keep an appropriate
distance from the vehicle ahead.
Even if the distance betw een your vehicle and the
vehicle detected 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.
You can also set the system to beep when a vehicle
detected in front of you co mes in and goes out of the
ACC with LSF detecting range. Change the ACC
Forward Vehicle Detect Beep setting.

■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 LSF accelerates your
vehicle to the set speed, and then maintains it.
While stationary and no vehicle is detected,
ACC with LSF automatically cancels and a
beeper sounds.
■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 vehicl e 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.
There are times when the vehicle speed will decrease when the accelerator pedal is
lightly applied.
A vehicle icon with dotted-line
contour appears on the MID.
1 When in Operation
Limitations
You may need to use the brake to maintain a safe
distance when using ACC with LSF. Additionally,
ACC with LSF may not work properly under certain
conditions.
2 ACC with LSF Conditions and Limitations
P. 371
When your vehicle stops automatically because a
vehicle detected ahead of you has stopped, the
distance between the two ve hicles will vary based on
the ACC with LSF following-distance setting, as
follows:
Short: 11.5 ft (3.5 m)
Middle: 11.5 ft (3.5 m)
Long: 13.1 ft (4.0 m)
Extra Long: 16.4 ft (5.0 m) 2 To Set or Change Following-distance P. 374

Stopped message appears on the MID.
When the vehicle ahead of you starts again,
the vehicle icon on the MI D blinks. If you press
the RES/+ /SET/– switch up or down, or
depress the accelerator pedal, ACC with LSF
operates again within the previously set
speed.1 A vehicle detected ahead is with in ACC with LSF range and slows
to a stop
3WARNING
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.
Never exit a vehicle when the vehicle is
