STARTING AND DRIVING
CAUTION
D When a slower vehicle in front of you leaves the lane,
the dynamic radar/laser cruise control will no longer
detect a vehicle ahead and will attempt to accelerate
the vehicle to the faster preset speed.
D When the vehicle−to−vehicle distance control is on
(on follow−up cruising), your cruising speed is
regulated in proportion to the speed of the vehicle
ahead, so increasing the preset vehicle speed using
the control lever does not accelerate the vehicle.
However, if the vehicle ahead leaves the lane, your
cruising speed will increase up to the preset speed
because the preset speed has been set higher using
the control lever.

You can select one of the following vehicle−to−vehicle
distances: "Long", "Middle" or "Short". Each time you
push the "DISP2" switch briefly, the setting changes from
"Long" to "Middle" to "Short" and then back to "Long".
You can confirm the setting on the multi−information
display.
It should be noted that pushing the "DISP2" switch longer will
change to another screen.
Your vehicle speed changes in proportion to the speed of
the vehicle ahead, maintaining the selected distance.
However, if the vehicle speed is slower, the selected
distance will be shorter than the designated distance.
When the vehicle−to−vehicle distance control mode is
activated or the multi−information display indicates "RADAR
READY", the vehicle−to−vehicle distance setting can be
changed.
