The ACC also slows the vehicle if it exceeds the set
speed (on a downhill grade, for example).
If there is no vehicle in front, ACC operates in the
same way as standard cruise control when the
vehicle is traveling above 10 mph (15 km/h).
IMPORTANT: Nothing should be put between
the driver and the seat, such as a heating pad,
massage pad, or similar items. Doing so may
keep the seat occupancy sensor from
functioning correctly.
ACC to 0 mph verifies seat occupancy before
resuming forward motion after slowing down to
0 mph.
ACC cannot be activated, or is automatically
deactivated, if:
•
the driver is not in their seat to activate the
seat occupancy sensor;
•
the vehicle is traveling slower than 10 mph (15
km/h);
•
the transmission is in neutral for more than 5
seconds;
•
reverse gear is selected;
•
the Anti-Lock Braking System (ABS) is
deactivated;
•
there is a malfunction in the brake system or
the electronic management system;
•
the distance sensor initialization is not yet
complete.
Activating Adaptive Cruise Control and
Setting the Speed
Activate ACC by setting the cruise speed, using the
controls on the steering wheel. See
When driving at the desired speed, press the –/SET
switch to activate ACC and store the set speed.
If cruise control is deactivated, the stored speed can
be activated again by pressing the +/RES switch on
the steering wheel switch pod. When activated, the
driver display shows the adaptive cruise control
telltale and the set speed.
If the brake pedal is pressed, ACC is deactivated
automatically.
If ACC becomes unavailable, a message appears on
the driver display screen. If the vehicle is
programmed to allow for standard cruise control, the
message displayed allows the driver to use standard
cruise control. See
Increasing or Reducing Adaptive Cruise
Control Speed
The ACC speed setting can only be set when driving.
Press the –/SET switch on the steering wheel switch
pod to set the cruise speed when the vehicle is
traveling at the desired speed. To decrease the set
cruise speed, press and hold –/SET.
Setting the Adaptive Cruise Control
Distance to the Vehicle in Front
If equipped, the ACC ICUC menu under 'Settings' >
'Safety Systems Settings' > 'More Information' >
'Adaptive Cruise Control' can be used to set the
overspeed and underspeed limits and the following
distance to the vehicle in front.
IMPORTANT: Make sure that the minimum
distance required by law is maintained.
Table 6.1.
Overtaking When Using Adaptive Cruise
