resumes.●
Even without canceling the cruise cont rol, the set speed can be increased by
first accelerating the vehicle to the desired speed and then pushing the lever
down to set the new speed.■
Automatic cruise control cancelation
Cruise control will stop maintaining the ve hicle speed in any of the following situa-
tions. ●
Actual vehicle speed falls more than approximately 10 mph (16 km/h) below the
preset vehicle speed.
At this time, the memorized set speed is not retained.●
Actual vehicle speed is below approximately 25 mph (40 km/h).●

2362-4. Using other driving systems
Driving in vehicle-to-vehicle distance control mode
This mode employs a radar sensor to detect the presence of vehicles up
to approximately 400 ft. (120 m) ah ead, determines the current vehicle-
to-vehicle following distance, and op erates to maintain a suitable follow-
ing distance from the vehicle ahead. Note that vehicle-to-vehicle distance will close in when traveling on long
downhill slopes.
Example of constant speed cruising
When there are no vehicles ahead The vehicle travels at the speed set by the driver. The desired vehicle-to-vehi-
cle distance can also be set by operat ing the vehicle-to-vehicle distance con-
trol.
Example of deceleration cruising
When the vehicle ahead is driving slower than the set speed
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a grea ter reduction in vehicle speed is nec-
essary, the system applies the brakes. A warning tone warns you when the
system cannot decelerate sufficiently to prevent your vehicle from closing in
on the vehicle ahead.

2372-4. Using other driving systems

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
