WARNING!
Leaving the ACC system on when not in
use is dangerous. You could accidentally
set the system or cause it to go faster than
you want. You could lose control and have
an accident. Always leave the system OFF
when you are not using it.
Setting The Following Distance In
ACC
The specified following distance for ACC can
be set by varying the distance setting be-
tween 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 displays
in the instrument cluster display.
To increase the distance setting, push the Dis-
tance 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 re-
lease. 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 “Sensed Ve-
hicle Indicator” 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 dis-
tance 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 infor-
mation 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.
NOTE:
The “Brake!” Screen in the instrument clus-
ter display is a warning for the driver to take
action and does not necessarily mean that
the Forward Collision Warning system is ap-
plying the brakes autonomously.
ACC Operation At Stop
In the event that the ACC system brings your
vehicle to a standstill while following a target
vehicle, if the target vehicle starts moving
within two seconds of your vehicle coming to
a standstill, your vehicle will resume motion
without the need for any driver action.
