" Each function is described below.
1 Setting the desired speed
The transmission must be in "D", "6" (sixth range), "5" (fifth
range) or "4"(fourth range) before you set the cruise control
speed.

After bringing the vehicle to the desired speed, press the
control lever downward in the "SET/COAST" direction and
release it. This sets the vehicle at that speed. At this time, the
multi-information display indicates settings such as the preset
vehicle speed, whether a vehicle is present ahead and
selected vehicle-to-vehicle distance. If there is no vehicle
detected ahead, the dynamic radar/laser cruise control screen
does not display the vehicle ahead. At this time, you may take
your foot off the accelerator pedal. If you need to accelerate
- for example, when passing - depress the accelerator pedal
enough for the vehicle to exceed the preset speed. When you
release the accelerator pedal, the vehicle will return to the
control prior to acceleration.
You cannot set a desired speed if the master warning light
comes on, the warning tone sounds and the multi-information
display indicates a warning message such as "Cruise not
Available", "Clean Radar Sensor" or "Check Cruise System".
If any of the above messages appears on the display, see
"Vehicle-to-vehicle distance control mode failure warning" on
page 349.
If you turn off the main switch while the warning message is
displayed, the warning message turns off and the
multi-information display switches to another screen. If no
warning message appears on the display, when you turn the
main switch on again, the setting can be made.
You can change the dynamic radar/laser cruise control screen
to another screen even while the warning message is
displayed.
