When not using ACC with LSF: Turn off adaptive
cruise by pressing the MAIN button. This also will
turn off the Lane Keeping Assist System (LKAS).
Do not use ACC with LSF under the following
conditions:
•On roads with heavy traf fic or while driving in
continuous stop and go traffic.
•On roads with sharp turns.
•On roads with steep downhill sections, as the set
vehicle speed can be exceeded by coasting. In such
cases, ACC with LSF will not apply the brakes to
maintain the set speed.
•On roads with toll collection facilities or other
objects between lanes of traffic, or in parking
areas, or faci lities with driv e through access.
How to use
■Press the MAIN button on
the steering wheel.

speed.
• The vehicle ahead of you is a motorcycle, bicycle, mobility scooter, or other small
vehicle.
• When there are animals in front of your vehicle.

■Automatic cancellation
The beeper sounds and a message appears on the driver information interface when
ACC with LSF is automatically canceled. An y of these conditions may cause the ACC
with LSF to automatically cancel:
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor in th e lower bumper 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.
• 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 enclos ed space, such as tunnel.
The ACC with LSF automatic cancellation can be also triggered by the following
causes. In these cases, the parking brake will be automatically applied.
• The driver’s seat belt is unfasten ed when the vehicle is stationary.
• The vehicle stops for mo re 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.

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 having to keep your foot on the brake or the
accelerator.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.
The radar sensor for ACC is shared with the collision
mitigation braking system
TM (CMBSTM).
2 Collision Mitigation Braking SystemTM
(CMBSTM) P. 471
3WARNING
Improper use of ACC can lead to a crash.
Use ACC only when driving on
expressways or freeways and in good
weather conditions.
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 ve hicle’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) ~.
■Gear position for ACC: In ( 2 or higher position. The radar sensor is in the
lower bumper.
Be careful not to have
the radar sensor cover
strongly impacted.
The camera is
located behind the
