ADJUSTING DISTANCE
This mode employs a radar sensor to detect the presence of a preceding v\
ehicle
up to approximately 328 ft (100 m) ahead, determines the current vehic\
le-to-vehicle
following distance and operates to maintain a preset following distance \
from the
vehicle ahead. These distances vary based on vehicle speed.
(1) (2) (3)
(1) Constant speed cruising when there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-\
to-
vehicle distance can also be set by operating the vehicle-to-vehicle dis\
tance
control.
(2) Deceleration cruising and follow-up cruising when a preceding vehicle
driving slower than the set speed appears When a slower vehicle is detected running ahead of you, the system
automatically decelerates your vehicle. When a greater reduction in vehi\
cle
speed is necessary, the system may apply the brakes (the brake lights w\
ill
come on at this time). The system will respond to changes in the speed \
of the
vehicle ahead in order to maintain the vehicle-to-vehicle distance set b\
y the
driver. A warning tone warns you when the system cannot decelerate suffi\
ciently
to prevent your vehicle from closing in on the vehicle ahead.
Note: Vehicle-to-vehicle distance will close in when traveling on long downhill
slopes.

ghts of
oncoming vehicles and taillights of preceding vehicles, then automatical\
ly toggles
between high and low beams accordingly.
