Setting The Following Distance In ACC
The specified following distance for ACC can be set by
varying the distance setting between four bars (lon-
gest), 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.
To adjust the distance setting, push the Distance Set-
ting Button and release. Each time the button is
pushed, the distance setting decreases by one bar (lon-
ger). Once the longest setting is reached, if the button
is pushed again it will be set to the shortest setting
available.
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 will then adjust
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 page 101.
The maximum braking applied by ACC is limited; how-
ever, the driver can always apply the brakes manually, if
necessary.
NOTE:
The brake lights will illuminate whenever the ACC sys-
tem applies the brakes.
A Proximity Warning will alert the driver if ACC predicts
that its maximum braking level is not sufficient to main-
tain 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 force.
NOTE:
The “BRAKE!” screen in the instrument cluster display
is a warning for the driver to take action and does not
necessarily mean that the Forward Collision Warning
system is applying the brakes autonomously.
Overtake Aid
When driving with Adaptive Cruise Control (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 accelera-
tion is triggered when the driver utilizes the left turn
signal and will only be active when passing on the left
hand side.
ACC Operation At Stop
In the event that the ACC system brings your vehicle to
a standstill while following a vehicle in front, if the
vehicle in front starts moving within two seconds of
your vehicle coming to a standstill, your vehicle will
resume motion without the need for any driver action.
If the vehicle in front does not start moving within two
seconds of your vehicle coming to a standstill, the
driver will either have to push the RES (resume) button,
or apply the accelerator pedal to reengage the ACC to
the existing set speed.
NOTE:
After the ACC system holds your vehicle at a standstill
for approximately three consecutive minutes, the park-
ing brake will be activated, and the ACC system will be
canceled.
While ACC is holding your vehicle at a standstill, if the
driver tries to leave the vehicle, the parking brake will
be activated and the ACC system will be canceled.
