Resuming the Set Speed
Note: Resume should only be used if
you are aware of the set speed and
intend to return to it.
Press and release RES. The vehicle
will return to the previously set speed.
The set speed will display
continuously in the information
display while the system is active.
Low Speed Automatic
Cancellation
The system is not functional at vehicle
speeds below 12 mph (20 km/h). An
audible alarm will sound and the
automatic braking will be released if
the vehicle drops below this speed.
Hilly Condition Usage
Note: An audible alarm will sound and
the system will shut down if it is
applying brakes for an extended period
of time. This allows the brakes to cool
down. The system will function
normally again when the brakes have
cooled down.
You should select a lower gear
position when the system is active in
situations such as prolonged downhill
driving on steep grades (i.e., driving in
mountainous areas). Additional
engine braking is needed in these
situations to reduce the load on the
vehicle's regular brake system to
prevent them from overheating.
Switching the System Off
Note: The set speed memory is erased
when you switch off the system.
Cruise Control
Press and release OFF or turn off the
ignition.
Detection Issues
The radar sensor has a limited field of
vision. It may not detect vehicles at all
or detect a vehicle later than expected
in some situations. The lead vehicle
graphic will not illuminate if a vehicle
is not detected in front of you.
