84 STARTING AND OPERATING
Setting The Following Distance In ACC
The specified following distance for ACC can be set by
varying the distance setting between four bars (longest),
three bars (long), two bars (medium) and one bar (short).
Using this distance setting and the vehicle speed, ACC
calculates and sets the distance to the vehicle ahead.
This distance setting will show in the instrument cluster
display.
Distance Settings
To increase the distance setting, push the Distance
Increase button and release. Each time the button is
pushed, the distance setting increases by one bar (longer).
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 display will show the
ACC Set With Target Detected Light. 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 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
appear in the instrument cluster display and a chime will
sound while ACC continues to apply its maximum braking
capacity.
NOTE:
The “BRAKE!” screen in the instrument cluster display is a
warning for the driver to take action and does not neces-
sarily mean that the Full Brake Control system is applying
the brakes autonomously.
Overtake Aid
When driving with ACC engaged and following a vehicle,
the system will provide an additional acceleration up to
the ACC set speed to assist in passing the vehicle.
This additional acceleration is triggered when the driver
utilizes the left turn signal and will only be active when
passing on the left hand side.
Display Warnings And Maintenance
“FRONT RADAR SENSOR TEMPORARILY
BLOCKED” WARNING
The “ACC Front Radar Sensor Temporarily Blocked”
warning will display and a chime will sound when
conditions temporarily limit system performance.
This most often occurs at times of poor visibility, such as
in snow or heavy rain. The ACC system may also become
temporarily blinded due to obstructions, such as mud, dirt
or ice. In these cases, the instrument cluster display will
read “ACC/FCW Unavailable Wipe Front Radar Sensor”
and the system will deactivate.
The “ACC Front Radar Sensor Temporarily Blocked”
message can sometimes be displayed while driving in
highly reflective areas (i.e. ice and snow, or tunnels with
reflective tiles). The ACC system will recover after the
vehicle has left these areas. Under rare conditions, when
the radar is not tracking any vehicles or objects in its path
this warning may temporarily occur.
