When depressing the acceler-
ator pedal
When constant speed control
mode is selected, your vehicle
will maintain a set speed without
controlling the vehicle-to-vehi-
cle distance. Select this mode
only when vehicle-to-vehicle dis-
tance control mode does not
function correctly due to a dirty
radar, etc.
1 With the cruise control off,
press and hold the cruise
control main switch for 1.5
seconds or more.
Immediately after the switch is
pressed, the dynamic radar cruise
control indicator will come on. After-
wards, it switches to the cruise con-
trol indicator.
Switching to constant speed control
mode is only possible when operat-
ing the switch wit h the cruise con-
trol off.
2 Accelerate or decelerate,
with accelerator pedal opera-
tion, to the desired vehicle
speed (at or above approxi-
mately 20 mph [30 km/h]) and press the “-SET” switch
to set the speed.
Cruise control “SET” indicator will
come on.
The vehicle speed at the moment
the switch is released becomes the
set speed.

Canceling and resuming the speed
setting: P.272
■Dynamic radar cruise control
with full-speed range can be set
when
●The shift lever is in D.
●The desired set speed can be set
when the vehicle speed is approx-
imately 20 mph (30 km/h) or more.
(However, when the vehicle speed
is set while driving at below
approximately 20 mph [30 km/h],
the set speed w ill be set to
approximately 20 mph [30 km/h].)
■Accelerating after setting the
vehicle speed
The vehicle can a ccelerate by oper-
ating the accelera tor pedal. After
accelerating, the set speed
resumes. However, during vehicle-
to-vehicle distance control mode,
the vehicle speed may decrease
below the set speed in order to
maintain the distance to the preced-
ing vehicle.
