different kinds of sensors, a radar sensor
located at the lower part of the front
bumper and a front sensor camera mounted
to the interior side of the windshield,
behind the rear view mirror.
Front Sensor
Camera The camera is located
behind the rearview
mirror.
Radar Sensor The radar sensor is at
the lower part of the
front bumper.
Collision Mitigation
Braking System
TM
(CMBS
TM) (P 510)
Can assist you when there is a possibility of
your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The
CMBS
TM is designed to alert you when a
potential collision is determined, as well as
to reduce your vehicle speed to help
minimize collision severity when a collision is
deemed unavoidable.
Adaptive Cruise Control
(ACC) with Low Speed
Follow (LSF)
* (P519)
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.
Adaptive Cruise Control
(ACC)
* (P 535)
Helps maintain a constant vehicle speed and
a set following interval behind a vehicle
detected ahead of yours, without you
having to keep your foot on the brake or
the accelerator.
Lane Keeping Assist
System (LKAS)
(P 550)
Provides steering input to help keep the
vehicle in the middle of a detected lane and

■Folding Down the Rear Seat(s)1Folding Down the Rear Seat(s)
The rear seat-back(s
*) can be folded down to
accommodate bulkier items in the trunk.
Never drive with the seat-back folded down and the
trunk lid open.
2 Exhaust Gas Hazard P. 75
To lock a seat-back upright, push it backwards until it
locks.
When returning the seat-back to its original position,
push it firmly back. Also, m ake sure all rear shoulder
belts are positioned in front of the seat-back, and the
center shoulder belt is re -positioned in the guide.
Make sure that the folded seat-back does not press
against the front passenger seat, as this can cause the
weight sensors in the front passenger seat to work
improperly.
2 Passenger Front Airbag Off Indicator P. 59
Make sure all items in the trunk or items
extending through the opening into the rear
seat is properly secured. Loose items can fly
forward if you have to brake hard.
The front seat(s) must be far enough forward so they
do not interfere with the rear seats as they fold
down.

Driving
Collision Mitigati on Braking SystemTM (CMBSTM)
Can assist you when there is a possibility of your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The CMBSTM is designed to alert you when a
potential collision is determined, as well as to reduce your vehicle speed to help
minimize collision severity when a collision is deemed unavoidable.
■How the system works
1 Collision Mitigation Braking SystemTM (CMBSTM)
Important Safety Reminder
The CMBS
TM is designed to reduce the severity of an
unavoidable collision. It do es not prevent a collision
nor stop the vehicle automati cally. It is still your
responsibility to operate the brake pedal and steering
wheel appropriately acco rding to the driving
conditions.
The CMBS
TM may not activate or may not detect a
vehicle in front of y our vehicle under certain
conditions: 2 CMBS
TM Conditions and Limitations P. 514
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 568
For directions on the prop er handling of the radar
sensor, refer to the following page. 2 Radar Sensor P. 570
When the CMBS
TM activates, it may automatically
apply the brake. It will be canceled when your vehicle
stops or a potential coll ision is not determined.
The radar sensor is at the
lower part of the front
bumper.
The camera is located
behind the rearview
mirror.
The system starts monitoring the roadway ah ead when your vehicle speed is about
3 mph (5 km/h) and there is a vehicle in front of you.
When to use
The CMBSTM activates when:●The speed difference between your vehicle and a vehicle or pedestrian detected in
front of you becomes about 3 mph (5 km/h) and over with a chance of a collision.
●Your vehicle speed is about 62 mph (100 km/h) or less and the system determines
there is a chance of a collision with:
- Vehicles detected in front of you that ar e stationary, oncoming, or traveling in your
same direction.
- A pedestrian who is detected in front of you.
●Your vehicle speed is above 62 mph (100 km/h), and the system determines there
is a chance of a collision with a vehicle detected in front of you traveling in your
same direction.

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 ve hicle, 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.1 Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)*
Important Reminder
As with any system, there are limits to ACC with LSF.
Use the brake pedal whenever necessary, and always
keep a safe interval between your vehicle and other
vehicles.
3WARNING
Improper use of ACC with LSF can lead
to a crash.
Use ACC with LSF only when driving on
expressways or freeways and in good
weather conditions.
3WARNING
ACC with LSF has limited braking
capability and may not stop your vehicle
in time to avoid a co llision with a vehicle
that quickly stops in front of you.
Always be prepared to apply the brake
pedal if the cond itions require.
When to use
■Vehicle speed for ACC with LSF: A vehicle is detected ahead within ACC with
LSF range – ACC with LSF operates at speeds up to 90 mph (145 km/h).
No vehicle is detected within ACC with LSF range – ACC with LSF operates at
the speed of 25 mph (40 km/h) or above.
