uuWhen Driving uAdaptive Cruise Control (ACC) with Low Speed Follow (LSF)*
Driving
■There is no vehicle ahead
Your vehicle maintains the set speed without
having to keep your foot on the brake or
accelerator pedal.
If there previously was a vehicle detected
ahead that kept your ve hicle from traveling at
the set speed, ACC with LSF accelerates your
vehicle to the set speed, and then maintains it.
■When you depress the accelerator pedal
You can temporarily increase the vehicle speed . In this case, there is no audible or
visual alert even if a vehicl e is in the ACC with LSF range.
ACC with LSF stays on unless you cancel it . Once you release the accelerator pedal,
the system resumes an appropriate speed fo r keeping the following-interval while a
vehicle ahead is within the ACC with LSF range.
There are times when the vehicle speed will decrease when the accelerator pedal is
lightly applied.
1 When in Operation
Limitations
You may need to use the brake to maintain a safe
interval when using ACC wi th LSF. Additionally, ACC
with LSF may not work properly under certain
conditions. 2 ACC with LSF Conditions and Limitations
P. 481
3WARNING
Exiting a vehicle that has been stopped
while the ACC with LSF system is operating
can result in the ve hicle moving without
operator control.
A vehicle that moves without operator
control can cause a crash, resulting in
serious injury or death.
Never exit a vehicle when the vehicle is
stopped by ACC with LSF.

certain conditions. Some examples of these conditions are listed below. Other
conditions may reduce some of the ACC functions.

Driving in bad weather (r ain, fog, snow, etc.).
■Roadway conditions
Driving on a snowy or wet roadway (obscure d lane marking, vehicle tracks, reflected
lights, road spra y, high contrast).
■Vehicle conditions
• The outside of the windshield is blocked by dirt, mud, leaves, wet snow, etc.
• An abnormal tire or wheel condition (Wrong sized, varied size or construction,
improperly inflated, co mpact spare tire, etc.).
• The camera temperature gets too high.
• The parking brake is applied.
• When the lower bumper next to the fog light
* is dirty.
• The vehicle is tilted due to a heavy load or suspension modifications.
• When tire chains are installed.
■ACC with LSF Conditions and Limitations1ACC with LSF Conditions and Limitations
The radar sensor for ACC with LSF is shared with the
collision mitigation braking system
TM (CMBSTM).

Always keep the radar sensor cover clean.
Never use chemical solvents or polishing powder for
cleaning the sensor cover. Clean it with water or a
mild detergent.
Do not put a sticker on the radar sensor cover or
replace the radar sensor cover.
If you need the radar sensor to be repaired, or
removed, or the radar se nsor cover is strongly
impacted, turn off the system by pressing the MAIN
button and take your vehicle to a dealer.
Have your vehicle checked by a dealer if you find any
unusual behavior of the system (e.g., the warning
message appears too frequently).

■Automatic ca ncellation
The beeper sounds and a message appears on the driver information interface when
ACC with LSF is automatically canceled. Any of these conditions may cause the ACC
with LSF to automatically cancel:
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor in the lower bumper next to the fog light
* gets dirty.
• The vehicle ahead of yo u 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 AC C with LSF range is too close to your
vehicle.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
• When the Maximum Load Limit is exceeded.
• When passing through an enclosed space, such as tunnel.
The ACC with LSF automatic cancellation ca n be also triggered by the following
causes. In these cases, the parking brake will be automatically applied.
• The driver’s seat belt is unfastene d when the vehicle is stationary.
• The vehicle stops for more than 10 minutes.
• The engine is turned off.
1Automatic cancellation
Even though ACC with LSF has been automatically
canceled, you can still resu me the prior set speed.
Wait until the condition that caused ACC with LSF to
cancel improves, then press the –/SET button.

Driving
Adaptive Cruise Control (ACC)*
Helps maintain a constant vehicle speed an d a set following-interval behind a vehicle
detected ahead of yours, without you havi ng to keep your foot on the brake or the
accelerator.
When ACC slows your vehicle by applying the brakes, your vehicle’s brake lights will
illuminate.1 Adaptive Cruise Control (ACC)*
Important Reminder
As with any system, there are limits to ACC. Use the
brake pedal whenever necessary, and always keep a
safe interval betw een your vehicle and other vehicles.
Be careful not to severely impact the radar sensor
cover.
3WARNING
Improper use of ACC can lead to a crash.
Use ACC only when traveling on open
highways in good weather.
3WARNING
ACC has limited braking capability.
When your vehicle speed drops below 22
mph (35 km/h), ACC will automatically
cancel and no longer will apply your
vehicle’s brakes.
Always be prepared to apply the brake
pedal when conditions require.
When to use
■Vehicle speed for adaptive cruise c ontrol: Desired speed in a range above
roughly 25 mph (40 km/h) ~ The radar sensor is in
the lower bumper
next to the fog light.
Be careful not to have
the radar sensor cover
strongly impacted.
The camera is
located behind
the rearview
mirror.

Driving
The system becomes ready to start sear ching for lane markings when all the
following conditions are met:
• The vehicle is traveling between about 45 and 90 mph (72 and 145 km/h).
• The vehicle is on a straight or slightly curved road.
• The turn signals are off.
• The brake pedal is not depressed.
• The wipers are not in continuous operation.
• The vehicle is not accelera ting or braking, and the steering wheel is not being
turned.
• The system makes a determination that th e driver is not actively accelerating,
braking or steering.
■How the System Activates1 How the System Activates
The RDM system may automa tically shut off and the
indicator comes and stays on.
