STARTING AND OPERATING 89
When ACC Is Active:
NOTE:
When you use the SET (-) button to decelerate, if the
engine’s braking power does not slow the vehicle suffi-
ciently to reach the set speed, the brake system will
automatically slow the vehicle.
The ACC system applies the brake down to 15 mph
(24 km/h) when following a vehicle ahead.
The ACC system maintains set speed when driving
uphill and downhill. However, a slight speed change on
moderate hills is normal. In addition, downshifting may
occur while climbing uphill or descending downhill. This
is normal operation and necessary to maintain set
speed. When driving uphill and downhill, the ACC
system will cancel if the braking temperature exceeds
normal range (overheated).
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
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 display will show the
Adaptive Cruise Control (ACC) Set With Target Vehicle
Light, 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 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.
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 Forward Collision Warning 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.
