WARNING!
Leaving the Adaptive Cruise Control
(ACC) system on when not in use is
dangerous. You could accidentally
activate the system or cause it to go
faster than you want. Always leave the
system off when you are not using it.
Setting the Speed
When vehicle reaches required speed,
press and release the button (SET - /
SET +). The display will show set speed
corresponding to vehicle current one.
Speed value will be indicated beside the
green symbol and above the distance
bars, in the center of the display.
Remove foot from accelerator pedal and
vehicle will continue at set speed.
Driver Override
If driver accelerates beyond the set
speed or faster than the car would do
autonomously, the time gap bars will
become gray to remember that in this
condition the system cannot control the
distance between vehicle and sensed
vehicle ahead. Vehicle speed will be
determined only by the accelerator pedal
position.
Changing Speed Setting
Once speed is set, driver can increase or
decrease it by respectively pressing the
button (SET +) or down (SET -). Speed
can be increased or decreased in two
ways:
• Pressing control once, set speed will
increase or decrease by one unit
corresponding to 1 MPH (1 km/h).
• Hold the control to increase or
decrease set speed by 5 MPH (10
km/h) at a time.
NOTE:
• When pressing the button (SET +) or
(SET -), the new set speed will be the
current speed of the vehicle.
• When using (SET -) control to
decelerate, if the engine braking power
does not slow down the vehicle
sufficiently to reach the set speed, the
Driving and Driver Assistance Systems
brake system will automatically slow
down the vehicle.
• The ACC system applies the brake
down to a full stop when following a
target vehicle. If an ACC host vehicle
follows a target vehicle to a standstill,
after two seconds the system will
not be able to resume driving the
car autonomously. At this point it is
necessary the intervention of the driver
on the multifunction control (press
RES) or press the accelerator pedal
(see "ACC Operation Before and During
Stop" in this chapter).
• The ACC system maintains set speed
when driving up hill and down hill.
However, a slight speed change on
moderate hills is normal. In addition,
downshifting or the use of the brake
may occur while climbing uphill or
descending downhill. This is normal
operation and necessary to maintain
set speed. When driving uphill and
downhill and the brake is used, the
ACC system will cancel if the braking
temperature exceeds normal range.
Temporary Deactivation
A soft tap on the brake pedal, pushing
the button (CANC), or normal brake
pressure while slowing the vehicle will
temporarily deactivate the ACC without
erasing the set speed memory. The
