1Adaptive 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 distance between your vehicle and other
vehicles.
The radar sensor for ACC with LSF is shared with the
collision mitigation braking system
TM (CMBS
TM).
2 Collision Mitigation Braking SystemTM
(CMBS
TM)* P. 392
When to use■Vehicle speed for ACC with LSF: A vehicle is
detected ahead within ACC with LSF range –
ACC with LSF operates at any vehicle speed.
No vehicle is detected within ACC with LSF
range – ACC with LSF operates at the speed of 25
mph (40km/h) or above.■Shift position for ACC with LSF: In
( D. The radar sensor is in the front grille.
How to use■Press the
MAIN button on
the steering wheel. ACC (green) is on in the
instrument panel.
ACC with LSF is ready to
use.

*
Driving
To cancel ACC with LSF, do any of the
following:
• Press the CANCEL button.
• Press the MAIN button.
u ACC with LSF indicator goes off.
• Depress the brake pedal.
u When the LSF function has stopped the
vehicle, you cannot cancel ACC with LSF
by depressing the brake pedal.
■Automatic cancellation
The beeper sounds and a message appears on the multi-information display when
ACC with LSF is automatically canceled. Any of these conditions may cause the ACC
with LSF to automatically cancel:
• Your vehicle speed slows to 22 mph (35 km/h) or below when a detected vehicle
goes out of the ACC with LSF range.
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor in the front grille gets dirty.
• The vehicle ahead of you cannot be detected.
• An abnormal tire condition is detected, or the tires are skidding.
• Driving on a mountainous road, or driving off road for extended periods.
• Abrupt steering wheel movement.
• When the ABS, VSA ® or CMBS
TM is activated.
• When the ABS or VSA ® system indicator comes on.
• When the vehicle is stopped on a very steep slope.
• When you manually apply the parking brake.
• When the detected vehicle within the ACC with LSF range is too close to your
vehicle.

1To Cancel
Resuming the prior set speed: After you have
canceled ACC with LSF, you can resume the prior set
speed while it is still displayed. Press the RES/+/SET/
– switch up when driving at a speed of at least 25
mph (40 km/h) or more.
Even if your vehicle speed has gone down to less than
25 mph (40 km/h), you can still resume the prior set
speed when ACC with LSF detects a vehicle ahead of
you.
You cannot set or resume in the following situations:•When the vehicle speed is less than 25 mph
(40km/h) and there is no vehicle detected in front
of your vehicle•When the MAIN button is turned off

Driving
FCW may not activate or may not detect a vehicle in front of your vehicle, and may
activate even when you are aware of a vehicle ahead of you, or when there is no
vehicle ahead, under the following conditions.■
FCW Limitations
Condition
●The distance between your vehicle and the vehicle ahead of you is too short.●A vehicle cuts in front of you at a slow speed, and it brakes suddenly.●A vehicle suddenly crosses in front of you.●When either your vehicle or the vehicle ahead of you accelerates rapidly.●The vehicle ahead of you is a motorcycle, a small vehicle, or a unique vehicle such as a tractor.●When you drive off-road or on a mountain road, or curved and winding road for an extended period that makes it difficult for the sensor/camera to
properly detect a vehicle in front of you.●When there are pedestrians or animals in front of your vehicle.●When you drive in bad weather (rain, fog, etc.).●A heavy load in the rear or modifications to the suspension tilts your vehicle.●An abnormal tire condition is detected (wrong tire size, flat tire, etc.).●When the windshield is blocked by dirt, mud, leaves, wet snow, etc.●When the temperature inside the system is high.●A sudden change between light and dark such as an entrance or exit of a tunnel.●You drive into the sunlight (e.g. at dawn or dusk).●When the windshield is dirty or cloudy.●When streetlight s are perceived as the taillight of a vehicle in front of yours.●When driving at night, the vehicle ahead of you is running with either taillight bulb burned out.●When you drive in the shadows of trees, buildings, etc.

Driving
Collision Mitigation Braking System
TM
(CMBS
TM
)*
Can assist you when there is a possibility of your vehicle colliding with a vehicle
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 when a collision is
deemed unavoidable to help minimize collision severity.
■How the system works
1 Collision Mitigation Braking System
TM (CMBS
TM)*
Important Safety Reminder
The CMBS
TM is designed to reduce the severity of an
unavoidable collision. It does not prevent collision nor
stop the vehicle automatically. It is still your
responsibility to operate the brake pedal and steering
wheel appropriately according to the driving
conditions.
The CMBSTM may not activate or may not detect a
vehicle in front of your vehicle under the following
conditions:
•The distance between your vehicle and the vehicle
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 ahead of you at high speed.•The vehicle ahead of you is a motorcycle or other
small vehicle.•A vehicle suddenly crosses in front of you.•When you drive on a curved or winding road that
makes it difficult for the sensor to properly detect a
vehicle in front of you.•When there are pedestrians or animals in front of
your vehicle.
A radar sensor starts to monitor if there is a vehicle in front of you when your
vehicle speed is above 10 mph (15 km/h).
The radar sensor is
in the front grille.
The CMBS
TM activates when the speed difference between your vehicle and a
vehicle detected in front of you becomes more than 10 mph (15 km/h) with a
chance of a collision.

Press this button for about one second to turn
on and off the system.
When the CMBS
TM is off:
• The beeper sounds.
• The CMBS
TM indicator in the instrument
panel comes on.
• A message on the multi-information display
reminds you that the system is off.
The CMBS
TM is in the previously selected ON or
OFF setting each time you start the engine.

The CMBS
TM may automatically shut off, and the
CMBS
TM indicator will come and stay on when:
•You drive off-road or on a mountain road for an
extended period.•You drive with the parking brake applied.•You drive in bad weather (rain, fog, snow, etc.)•The radar sensor cover is blocked by dirt, mud, dry
leaves, wet snow, etc.•An abnormal tire condition is detected (wrong tire
size, flat tire, etc.)
Once the conditions that caused the CMBS
TM to shut
off improve, the system comes back on.
