When driving Example of follow-up cruising
When following a vehicle driving slower than the set speed The system continues follow-up cruising while adjusting for changes in the
speed of the vehicle ahead in order to maintain the vehicle-to-vehicle dis-
tance set by the driver.
Example of acceleration
When there are no longer any vehicl es ahead driving slower than the
set speed The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.
Approach warning
When your vehicle is too close to a vehicle ahead, and sufficient auto-
matic deceleration via the cruise co ntrol is not possible, the display will
flash and the buzzer will sound to al ert the driver. An example of this
would be if another driver cuts in fron t of you while you are following a
vehicle. Apply the brakes to ensure an appropria te vehicle-to-vehicle dis-
tance.
■ Warnings may not occur when
In the following instances, there is a possibility that the warnings will not
occur:
● When the speed of the vehicle ahead matches or exceeds your
vehicle speed
● When the vehicle ahead is traveling at an extremely slow speed
● Immediately after the cruise control speed was set
● At the instant the accelerator is applied
