Adaptive Cruise Control (ACC) with Low Speed
Follow (LSF)

Helps maintain a constant vehicle speed and a set following-interval behind a vehicle
detected ahead of yours and, if the detected vehicle comes to a stop, can decelerate
and stop 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.

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-interval from the
vehicle ahead.

2 To Set or Change Following-Interval P. 409

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 Operation

When 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 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 interval
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
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 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 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 ACC with LSF range and slows to a stop

Your vehicle also stops, automatically. The
Stopped message appears on the driver
information interface.
When the vehicle ahead of you starts again,
the vehicle icon on the 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.

Lane Keeping Assist System (LKAS)

Important Safety Reminders
The LKAS is for your convenience only. It is not a
substitute for your vehicle control. The system does
not work if you take your hands off the steering
wheel or fail to steer the vehicle.

2 Driver Information Interface Warning and

Information Messages P. 119

Do not place objects on the instrument panel.
Objects may reflect on the front windshield and
prevent correct detection of the traffic lanes.

The LKAS only alerts you when lane drift is detected
without a turn signal in use. The LKAS may not detect
all lane markings or lane departures; accuracy will
vary based on weather, speed, and lane marker
condition. It is always your responsibility to safely
operate the vehicle and avoid collisions.

The LKAS is convenient when it is used on freeways.

The LKAS may not work properly or may work
improperly under the certain conditions:
