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 comes to a stop, can decelerate
and stop your ve hicle, without yo u 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 interval between your vehicle and other
vehicles.
Be careful not to severely impact the radar sensor
cover.
3WARNING
Improper use of ACC wi th 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 collision with a vehicle that quickly
stops in front of you.
Always be prepared to apply the brake
pedal if the conditions 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 (40 km/h) or above.
■Gear position for ACC with LSF: In ( D. The radar sensor is
behind the emblem.
The camera is
located behind
the rearview
mirror.

■How to activate the system1Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)
When the MAIN button is pressed, both ACC with
LSF and the Lane Keeping Assist System (LKAS) are
either turned on or off.
ACC with LSF may not work properly under certain
conditions. 2 ACC with LSF Conditions and Limitations
P. 397
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).
Do not use ACC with LSF under the following
conditions:
•On roads with heavy traf fic or while driving in
continuous stop and go traffic.
•On roads with sharp turns.
•On roads with steep downhill sections, as the set
vehicle speed can be exceeded by coasting. In such
cases, ACC with LSF will not apply the brakes to
maintain the set speed.
•On roads with toll collection facilities or other
objects between lanes of traffic, or in parking
areas, or faci lities with driv e through access.
How to use
■Press the MAIN button
on the steering wheel. ACC
(green) is on in the
instrument panel.
ACC with LSF is ready to
use.

Driving
When driving at about 25 mph (40 km/h) or above: Take your foot off the
pedal and press the −/SET button when you reach the desired speed. The moment
you release the button, th e set speed is fixed, and ACC with LSF begins.
When driving at slower th an about 25 mph (40 km/h): If the vehicle is moving
and the brake pedal is not depressed, pr essing the button fixes the set speed to
about 25 mph (40 km/h) regardless of current vehicle speed. If your vehicle is
stationary, you can set the vehicle speed even with the brake pedal depressed.

When ACC with LSF st arts operating, the
vehicle icon, interval bars and set speed
appear on the driver information interface.
When you use ACC with LSF, Straight Driving
Assist (a feature of the Electric Power Steering

By enabling the steering system to
automatically compensate for natural steering
pull, Straight Driving Assist makes it easier for
you to keep your vehicle in a straight line.

■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 ve hicle’s set following-interval from the
vehicle ahead.
2 To Set or Change Following-Interval P. 400
When a vehicle whose speed is slower than
your set speed is detected in front of you, your
vehicle starts to slow down.
■When in Operation1When in Operation
If the vehicle 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 driver
information interface.
Depress the brake pedal, and keep an appropriate
interval from the vehicle ahead.
Even if the interval 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, gradua lly increasing the interval
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.
■When you depress the accelerator pedal
You can temporarily increase th e 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 an appropriate speed for keeping the following-interval while a
vehicle ahead is within the ACC with LSF range.
■A vehicle detected ahead is within AC C with LSF range and slows to a stop
Your vehicle also stop s, automatically. The
Stopped message appears on the driver
information interface.
When the vehicle ahead of you starts again,
the vehicle icon on th e driver information
interface blinks. If you press the RES/+ or
−/SET button, or depress the accelerator
pedal, ACC with LSF operates again within the
prior set speed.

Limitations
You may need to use the brake to maintain a safe
interval when using ACC wi th LSF. Additionally, ACC
with LSF may not work properly under certain
conditions. 2 ACC with LSF Conditions and Limitations
P. 397
3WARNING
Exiting a vehicle that has been stopped
while the ACC with LSF system is operating
can result in the ve hicle 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 driver
information interface
1 When you depress the accelerator pedal
While the accelerator pedal is depressed, the system
does not apply the brakes to keep the following
interval, as well as the BRAKE message on the driver
information interface does not appear.
