■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 obstacles, as well as providing assistance
with braking.
If the only rear sensors are turned off using the parking sensor system, the assistive
braking will not work when reversing.

sensors, please refer to the following page.

The vehicle will release the brake and start moving a
few seconds after the system is activated. To keep the
vehicle stopped, keep the brake pedal depressed or
put the transmission into
( P.
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
on, or when using a chas sis dynamometer or free
rollers for inspection or when washing the car in
conveyor type car wash machine.
If you put any accessories on or around the rear
sensors, the Low Speed Br aking Control System may
activate if it detects these accessories as an obstacle.
In this case, turn off the rear sensor. 2 Customized Features P. 376Audible Alert

■Assistive driving power suppression
When the vehicle is stopped or moving at less than 6 mph (10 km/h) and there is an
obstacle such as a wall near the front of or back of the vehicle, if the accelerator
pedal is depressed more than necessary, the system will inform you with a visual and
audible alert. At the same time, the sy stem will prevent sudden forward or
backwards movement by limiting the outpu t of the power system, then assistive
braking will activate when you get closer to the obstacle.
Assistive driving power suppression will not activate in the following situations.
When moving forward:
• When on a steep slope or the shift position is in
(P, (R, or (N.
When reversing:
• When on a steep slope or the shift position is in a position other than
(R.
If the only rear sensors are turned off usi ng the parking sensor system, the assistive
driving power suppression will not work when reversing.

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.
Conditions for assistive braking cancellation.
• A certain amount of time has passed since activation.
The system may not operate correctly under the following conditions:
■Examples of obstacles the sonar sensors cannot detect
• Obstacles that do not reflect sound waves well, such as people, snow, cloth,
sponges, etc.
• Thin obstacles such as fenc es, bicycles, sign posts, etc.
• Short or small obstacles.
• Obstacles immediately in front of the bumper.
• Obstacles that are not perp endicular to the ground.
• Moving objects or obstacles that suddenly enter the road.
■Conditions for Cancellation
■Low Speed Braking Control System Conditions and Limitations
1Conditions 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
■Examples of situations where the sonar sensors cannot detect obstacles
• The sonar sensors are dirty (cover ed by snow, water, mud, etc.).
• The vehicle is too hot or cold.
• The steering wheel is turned sharply when approaching the obstacle at an angle.
■Examples of other cases where the system may not work correctly
• The vehicle is tilted due to heavy load or suspension modifications.
• Bad weather conditions such as heavy rain, fog, snow, sandstorms, etc.
• The ambient temperature/humidity is too high or low.
• When going down a very steep slope.
• When close to other vehicles with sonar sensors or other objects that emit
ultrasonic waves.
• An abnormal tire or wheel condition (incorre ct sizes, varied sizes or construction,
improperly inflated, etc.).
■Situations where the system may activate even without risk of a collision
• When passing through short or narrow gates.
• When driving on uneven surfaces, gr assy areas, or places with steps.
• When a sloped pillar or wall is protruding from a high position.
• When there are obstacles next to the road.
• When driving toward flags, curtains, tree branches, railroad crossing bars, etc.
• When driving on flooded roads.

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 detect ed vehicle comes to a stop, can decelerate
and stop your ve hicle, without you having to keep your foot on the brake or the
accelerator.
When ACC with Low Speed Follo w slows your 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.
For directions on the prop er handling of the radar
sensor, refer to the following page. 2 Radar Sensor P. 570
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 568
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 25 mph (40 km/h) or above.
■Shift position for ACC with Low Speed Follow: In ( D or .B

2 ACC with Low Speed Follow Conditions
and Limitations P. 521
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 frequent la ne-change or continuous
stop and go traffic, ACC with Low Speed Follow
cannot keep an appropriate distance between your
vehicle and the vehicle ahead of you.

objects between lanes of traffic, or in parking
areas, or faci lities with driv e through access.
•On roads with bad weather (rain, fog, snow, etc.),
ACC with Low Speed Follow may not detect the
distance between your vehicle and the vehicle
ahead of you properly.
•On roads with slippery or icy surfaces. The wheels
may spin out and your vehi cle may lose the control
on the condition.
