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.
3
WARNING
ACC with LSF 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.

Exiting a vehicle that has been stopped
while the ACC with LSF system is operating
can result in th e 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.
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 about 25 mph (40 km/h) or above.■Gear position for ACC with LSF: In

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 between your vehicle and other
vehicles.
The radar sensor for ACC with LSF is shared with the

When driving at about 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 about 25 mph (40 km/h): If the vehicle is moving
and the brake pedal is not depressed, pressing the switch fixes the set speed to
about 25 mph (40 km/h) regardless of cu rrent 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 multi-information display. ■

■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. 360
When a vehicle whose speed is slower than
you r se t spe e d c om e s in or cu t s in f r on t of yo u
and is detected by the radar and the camera,
your vehicle starts to slow down.
■
When in Operation
1When 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 and a message
appears on the multi-information display.
Depress the brake pedal, and keep an appropriate
distance from the vehicle ahead.
Even if the distance between 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 comes in and goes out of the
ACC with LSF detecting range. Change the ACC

■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 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 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
previously set speed.A vehicle icon with dotted-line
contour appears on the multi-
information display

ACC with LSF may not work properly under certain
conditions.
2 ACC with LSF Conditions and Limitations
P. 357
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 following-distance setting, as
