402 uu When Driving u Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)
Driving Adaptive Cruise Control (ACC) with Low Speed
Follow (LSF) Helps maintain a constant vehicle speed an d a set following-interval behind a vehicle
detected ahead of yours and, if the detect ed vehicle comes to a stop, can decelerate
and stop your vehicle, 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 betw een your vehicle and other
vehicles.
Be careful not to severely impact the radar sensor
cover.3
WARNING Improper use of ACC wi th LSF can lead to a
crash.
Use ACC with LSF only when driving on
expressways or freeways and in good
weather conditions.
3
WARNING ACC with LSF has limite d braking capability
and may not stop your vehicle in time to
avoid a collision with a vehicle that quickly
stops in front of you.
Always be prepared to apply the brake
pedal if the conditions 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.
■ Gear position for ACC with LSF: In ( D
