256 STARTING AND OPERATING
Distance Setting 2 Bars (Medium)
Distance Setting 1 Bar (Short)
To increase the distance setting, push the
Distance Setting Increase button and release.
Each time the button is pushed, the distance
setting increases by one bar (longer).
To decrease the distance setting, push the
Distance Setting Decrease button and release.
Each time the button is pushed, the distance
setting decreases by one bar (shorter).
If there is no vehicle ahead, the vehicle will
maintain the set speed. If a slower moving
vehicle is detected in the same lane, the
instrument cluster displays the ACC Set with
Target Light icon, and the system adjusts
vehicle speed automatically to maintain the
distance setting, regardless of the set speed.
The vehicle will then maintain the set distance
until:
The vehicle ahead accelerates to a speed

above the set speed.
The vehicle ahead moves out of your lane or

view of the sensor.
The distance setting is changed.

The system disengages. Refer to the informa-

tion on ACC Activation.
The maximum braking applied by ACC is limited;
however, the driver can always apply the brakes
manually, if necessary.
NOTE:
The brake lights will illuminate whenever the
ACC system applies the brakes.
A Proximity Warning will alert the driver if ACC
predicts that its maximum braking level is not
sufficient to maintain the set distance. If this
occurs, a visual alert "BRAKE" will flash in the
instrument cluster display and a chime will
sound while ACC continues to apply its
maximum braking capacity.
