- The adaptive cruise control system will
not brake by itself if you put your foot on
the accelerator pedal. Doing so can over-
ride the speed and d istance regulation .
- When approaching stationary objects
such as stopped traffic, adaptive cruise
control will not respond and pre sense
front will have limited function.
- The adaptive cru ise control system and
pre sense front do not react to people,
animals, objects cross ing the road or on-
coming objects.
- The function of the rada r senso rs can be
affected by reflective objects such as
guard ra ils, the entra nce to a tunnel,
heavy rain or ice.
- Never follow a veh icle so closely that you
cannot st op your vehi cle safe ly. The
adap t ive cruise cont ro l canno t slow or
brake the ve hicle safe ly when you follow
another vehicle too closely. Always re-
member that the automatic braking
function cannot br ing the veh icle to a
sudden or emergency stop under these
condit ions .
- To prevent unintended operation, always
switch ACC off when it is not being used.
