Adaptive Cruise Control (ACC) with Low Speed Follow

Driving

Adaptive Cruise Control (ACC) with Low Speed
Follow

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 Low Speed Follow slows your vehicle by applying the brakes, your
vehicle’s brake lights will illuminate.

Adaptive Cruise Control (ACC) with Low Speed Follow

Important Reminder

As with any system, there are limits to ACC with Low
Speed Follow. Use the brake pedal whenever
necessary, and always keep a safe interval between
your vehicle and other vehicles.

For directions on the proper handling of the radar
sensor, refer to the following page.

Radar Sensor

P. 501

WARNING

Improper use of ACC with Low Speed
Follow can lead to a crash.

Use ACC with Low Speed Follow only when
driving on expressways or freeways and in
good road and weather conditions.

WARNING

ACC with Low Speed Follow 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 Low Speed Follow:

A vehicle is detected ahead

within ACC with Low Speed Follow range

– ACC with Low Speed Follow

operates at speeds up to 90 mph (145 km/h).

No vehicle is detected within ACC with Low Speed Follow range

– ACC with

Low Speed Follow operates at the speed of 25 mph (40 km/h) or above.

When not using ACC with Low Speed Follow: Turn
off adaptive cruise by pressing the

button.

Do not use ACC with Low Speed Follow under the
following conditions:

•

On roads with heavy traffic 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 Low Speed Follow 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 facilities with drive through access.

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, the set speed is fixed, and ACC with Low Speed Follow begins.

When driving slower than about 25 mph (40 km/h):

If the vehicle is moving

and the brake pedal is not depressed, pressing the button fixes the set speed to
about 25 mph (40 km/h) regardless of current vehicle speed. If the vehicle is
stationary, you can set the vehicle speed even with the brake pedal depressed.

When ACC with Low Speed Follow starts
operating, the vehicle icon, interval bars and set
speed appear on the driver information interface.

When you use ACC with Low Speed Follow,
Straight Driving Assist (a feature of the Electric
Power Steering system) is activated.
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 Low Speed Follow monitors if a vehicle ahead of you enters the ACC with
Low Speed Follow range. If a vehicle is detected doing so, the ACC with Low Speed
Follow system maintains or decelerates your vehicle’s set speed in order to keep the
vehicle’s set following interval from the vehicle ahead.

When a vehicle whose speed is slower than

■

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 Low Speed Follow
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 Low Speed Follow range.
ACC with Low Speed Follow 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 Low Speed Follow
range.

When in Operation

Even if the interval between your vehicle and the
vehicle detected ahead is short, ACC with Low Speed
Follow 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 in
front of you comes in and goes out of the ACC with
Low Speed Follow detecting range. A vehicle detect
beep on and off can be selected.

WARNING

Exiting a vehicle that has been stopped
while the ACC with Low Speed Follow
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
