returns to constant speed cruising.
Press  the  cruise  control  main
switch  to  activate  the  cruise
control.
Dynamic  radar  cruise  control  indi-
cator  will  come  on  and  a  message
will be displayed on the multi-infor-
mation display.
Press  the  switch  again  to  deacti-
vate the cruise control.
If  the  cruise  control  main  switch  is  pressed  and  held  for  1.5  seconds  or
more, the system turns on in constant speed control mode. ( P. 284)
Accelerate  or  decelerate,  with
accelerator  pedal  operation,  to
the  desired  vehicle  speed  (at  or
above  approximately  30  mph
[50 km/h]) and press the “- SET”
switch to set the speed.
Cruise  control  “SET”  indicator  will
come on.
