Cruise Control Function
While this function is operating, the
headway control operation is cancelled
and only the cruise control function
operates.
The vehicle speed can be set more than
about 25 km/h (16 mph).
Use the cruise control function on
expressways and other highways which do
not require a lot of repeated acceleration
and deceleration.
WARNING
Do not use the cruise control function
in the following locations:
Otherwise, it could lead to an accident.
 
 Roads with sharp curves and where
vehicle traf¿ c is heavy and there is
insuf¿ cient space between vehicles.
(Driving under these conditions
using the cruise control function is
not possible)
  Steep down slopes (Set speed may be
exceeded because suf¿ cient engine
braking cannot be applied)
  Slippery roads such as ice or snow-
bound roads (Tyres could spin
causing you to lose vehicle control)

Always drive carefully:
The warnings and brake control
will not operate after the headway
control function is cancelled and the
