■Detection limitations
• A vehicle or pedestrian suddenly crosses in front of you.
• The distance between your vehicle and the vehicle or pedestrian ahead of you is
too short.
• A vehicle cuts in front of you at a slow speed, and it brakes suddenly.
• When you accelerate rapidly and approach the vehicle or pedestrian ahead of you
at high speed.
• The vehicle ahead of you is a motorcycle, bicycle, mobility scooter or other small
vehicle.
• When there are animals in front of your vehicle.
• When you drive on a curved, winding or undulating road that makes it difficult for
the sensor to properly detect a vehicle in front of you.
• The speed difference between your vehicle an d a vehicle or pedestrian in front of
you is significantly large.
• An oncoming vehicle suddenly comes in front of you.
• Another vehicle suddenly comes in front of you at an intersection, etc.
• Your vehicle abruptly crosses over in front of an oncoming vehicle.
• When driving through a narrow iron bridge.
• When the lead vehicle suddenly slows down.

■Assistive braking
Assistive braking provides a visual and audible alert when the vehicle is moving
between approximately 1 and 6 mph (2 and 10 km/h) and there is the possibility of
a collision with a detected wall or other ob stacles, as well as providing assistance
with braking.
If the only rear sensors are turned off usi ng the parking sensor system, the assistive
braking is not working when reversing.

In order to prevent the sy stem from activating when
not needed, always turn it off during vehicle
maintenance, when loading on ships, trucks, and so

Driving
Conditions for assistive driving power suppression.
• When the accelerator is no longer depressed.
• When the accelerator is depresse d for approximately four seconds.
• When the brake pedal is depressed.
• When the steering wheel is tu rned and a collision avoided.
Conditions for assistive braking cancellation.
• A certain amount of time ha s passed since activation.
The system may not operate correct ly in the following conditions:
■Examples of obstacles the sonar sensor cannot detect
• Obstacles that do not refl ect sound waves well, such as people, snow, cloth,
sponges, etc.
• Thin obstacles such as fences, bicycles, sign posts, etc.
• Short or small obstacles.
• Obstacles immediately in front of the bumper.
• Moving objects or obstacles that suddenly enter the road.
• Obstacles that are not pe rpendicular to the ground.
■Conditions for Cancellation
■Low Speed Braking Control System Conditions and
Limitations
1 Conditions for Cancellation
After Low Speed Braking Control has activated once,
it will not activate again for the same obstacle.
They can be activated again after driving for a certain
distance after last activation.
Low Speed Braking Control ac tivates separately when
moving forward and reversing. (For example, if it
activates when moving forwar d, it can be activated
again immediately if reversing.)
However, if assistive braking has been activated, in
order to activate assistiv e driving power suppression
again, it is necessary to drive for a certain distance to
reset the system.

Driving
Adaptive Cruise Control (ACC) with Low Speed
Follow
Helps maintain a constant vehicle speed a nd 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 vehicle, without you having to keep your foot on the brake or the
accelerator.
When ACC with Low Speed Follow slows y our vehicle by applying the brakes, your
vehicle’s brake lights will illuminate.
1 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.
3WARNING
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.
3WARNING
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 wi th 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 about 25 mph (40 km/h) or above.
■Shift position for ACC with Low Speed Follow: In ( D or (S.
The radar sensor is
behind the emblem.
The camera is
located behind the
rearview mirror.

Do not use ACC with Low Speed Follow under the
following conditions.
•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 faci lities with driv e through access.

Driving
When driving 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 current vehicle speed. While stationary and a
vehicle is ahead of you, th e vehicle speed can be set, 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 gauge.
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 ve hicle 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 followi ng-interval from the vehicle ahead.
2To Set or Change Following-interval P. 507
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 Operation1 When in Operation
If the vehicle detected ahead of you slows down
abruptly, or if a nother vehicle is de tected cutting in
front of you, a beeper so unds and a message appears
on the driver information interface, and the head-up
