APPROACH WARNING
While you are cruising in the vehicle−to−
vehicle distance control mode, if the ve-
hicle ahead decelerates abruptly or
another vehicle cuts in ahead of you, in-
adequate braking will make your vehicle
become closer to the vehicle ahead of you
and the display will flash and beep.

speed.
The vehicle ahead is cruising at a
if
faster speed than yours. (The dis-
tance between the vehicles will be-
come longer.)
The vehicle ahead is at a stop or
driving very slowly. Pay
attention to a very slow vehicle at
the end of the line in heavy traffic
or at a tollgate.
The speed has just been set.

or has just been released.

hicle−to−vehicle distance control cruis-
ing.

dynamic laser cruise control function is
automatically cancelled and a warning
code appears on
special
"VEHICLE−TO−VEHICLE
CONTROL MODE FAILURE WARNING"
on page 235.)
However, if the glass sensor is covered
with icicle or any substance, dirt may
not be detected.
