Conditions for assistive driving power suppressionY
• 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 correct ly in the following conditions:
■Examples of obstacles the sonar sensor cannot detect
• Obstacles that do not reflect 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 perp endicular 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.
It 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.

■Examples of situations where the so nar sensor cannot detect obstacles
• The sonar sensor is dirty (covered 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.
• An abnormal tire or wheel condition (incor rect sizes, varied sizes or construction,
improperly inflated, compact spare tire
*, etc.).
• 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.
■Situations where the system may activa te 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.

Driving
Low Speed Braking Control*
Using sonar sensors located on the front an d rear bumpers and the front grille, this
system can detect if there is danger of a potential collision with a wall or other
obstacle during normal driving. The system then assists in avoiding collisions and
reducing damage from impact through assistive braking.
1 Low Speed Braking Control*
If the Low Speed Braking Control activates in a
situation where you do not want automatic brake
application (such as when the vehicle is between two
railroad crossing gates), si mply press the brake pedal
to deactivate the system and then continue to drive
as intended.
3WARNING
The Low Speed Braking Control System
cannot avoid all collisions and may not
reduce damage in each situation where the
accelerator is mistaken ly or aggressively
pressed. Overreliance on the system may
result in a collision with serious injury or
death. Always check your surroundings,
your shift position, and your pedal use.
Driver remains responsible for safely
operating the vehicle.

Driving
The Low Speed Braking Control 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 only the rear sensors are turned off using the parking sensor system, the Low
Speed Braking Control is not working when reversing.

The vehicle will release the brake a few seconds after
the system is activated. Keep the brake pedal
depressed.
When the system activates, the engine may stop
automatically. Start the engine by normal operation if
the engine stops. 2 Starting the Engine P. 433
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; when using a chassis dy namometer or free rollers
for inspection; or when washing the car in conveyor
type car wash machine.

For the sonar sensors to work properly, do not:
•Place stickers or other objects on or around the
sensors.
•Hit the area around the sensors.
•Attempt to take apart any sensor.
•Put any accessories on or around the sensors.
Consult with a dealer if:
•A sensor has been subjected to shock.•Work needs to be done to the area around a
sensor.
In the following cases, the sonar sensors may not
work properly. Have your ve hicle checked by a dealer.
•The front or rear bumper has made contact with a
hill, parking block, curb, embankment, etc.
•The vehicle has been involv ed in a frontal or rear
collision.
•The vehicle has been driven through a deep

The corner and center sensors monitor ob stacles around your vehicle, and the
beeper, driver information interface and a udio/information screen let you know the
approximate distance between your vehicle and the obstacle.
■The sensor location and range
1 Parking Sensor System*
Even when the system is on, always confirm if there is
no obstacle near your ve hicle before parking.
The system may not work properly when:
•The sensors are covered with snow, ice, mud, or
dirt.
•The vehicle has been out in hot or cold weather.•There is something nearby that emits ultrasonic
waves or high frequency sounds.
•Driving in bad weather (rain, fog, snow, etc.).•Any accessories have been put on or around the
sensors.
uIf you put any accessories on or around the rear
sensors, the system may acti vate if it detects these
accessories as an obstacle. In this case, turn off the
rear sensor. 2 Customized Features P. 367
The system may not de tect these obstacles:
•Thin or low objects.
•Sonic-absorptive materials, such as snow, cotton,
or sponge.
•Objects directly under the bumper.
The system may falsely de tect obstacles in the
following situations:
•The vehicle is on uneven su rface, such as grass,
bumps, or a hill.
•When close to other vehicl es with sonar sensors or
other objects that em it ultrasonic waves.
•There is splashing water near the sensors due to
heavy rains, etc.
