Driving
Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)
Helps maintain a constant vehicle speed an d a set following-interval behind a vehicle
detected ahead of yours and, if the detect ed vehicle slows to a stop, decelerates and
stops your vehicle, without you having to keep your foot on the brake or the
accelerator.
When ACC with LSF slows your vehicle by applying the brakes, your vehicle's brake
lights will illuminate.1 Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)
Important Reminder
As with any system, there are limits to ACC with LSF.
Use the brake pedal whenever necessary, and always
keep a safe distance betw een your vehicle and other
vehicles.
3WARNING
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.
3WARNING
ACC with LSF has limited braking
capability and may not stop your vehicle
in time to avoid a co llision with a vehicle
that quickly stops in front of you.
Always be prepared to apply the brake
pedal if the cond itions require.
When to use
■Vehicle speed for ACC with LSF: A vehicle is detected ahead within ACC with
LSF range – ACC with LSF operates at speeds up to 90 mph (145 km/h).
No vehicle is detected within ACC with LSF range – ACC with LSF operates at
the speed of 25 mph (40km/h) or above.
■Gear position for ACC with LSF: In ( D. The radar sensor is
in the front grille.
The camera is
located behind
the rearview
mirror.

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. 393
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, your vehicle
starts to slow down.
■When in Operation1 When in Operation
If the vehicle detected ahead of you slows down abruptly, or
if another vehicle is detected cutting in front of you, the
beeper sounds, a message appears on the multi-information
display, and the head-u p warning lights come on.
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 ve hicle 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.

Driving
■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.
■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 detected ahead is within ACC with LSF range and slows to a stop
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 multi-information
display 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.
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. 390
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: 13.1 ft (4.0 m)
Middle: 14.2 ft (4.3 m)
Long: 15.3 ft (4.7 m)
Extra Long: 16.4 ft (5.0 m) 2 To Set or Change Following-Distance
P. 393
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
stopped by ACC with LSF.
A vehicle icon with dotted-line
contour appears on the multi-
information display
