216 DRIVING AND OPERATING
Resuming a Set Speed
If ACC is set at a desired speed and
then the brakes are applied, ACC is
disengaged without erasing the set
speed from memory.
To begin using ACC again, press RES+
up briefly.
If the vehicle is moving, it returns
to the previous set speed.
If the vehicle is stopped with the
brake pedal applied, press RES+
and release the brake pedal. ACC
will hold the vehicle until RES+ or
the accelerator pedal is pressed.
A green ACC indicator and the set
speed display on the infotainment
display. The vehicle ahead indicator
may be flashing if a vehicle ahead was
present and moved. See Approaching
and Following a Vehicle later in this
section.
Once ACC has resumed, if there is no
vehicle ahead, if the vehicle ahead is
beyond the selected following gap,
or if the vehicle has exited a sharp
curve, then the vehicle speed will
increase to the set speed.
Increasing Speed While ACC Is at a
Set Speed
Do one of the following:
Use the accelerator to get to the
higher speed. Press SET and
release the accelerator pedal. The
vehicle will now cruise at the
higher speed.
When the accelerator pedal is
pressed, ACC will not brake
because it is overridden.
A warning message will appear on
the Driver Information Center
(DIC) and HUD. See Cruise Control
Messages 0 142.
Press and hold RES+ until the
desired set speed is displayed,
then release it.
To increase speed in small
increments, press RES+ to the first
detent. For each press, the vehicle
goes 1 km/h (1 mph) faster.
To increase speed in larger
increments, press RES+ to the
second detent. For each press, the
vehicle speed increases to the next
5 km/h (5 mph) mark on the
speedometer.
The set speed can also be increased
while the vehicle is stopped.
If stopped with the brake applied,
press RES+ until the desired set
speed is displayed.
If ACC is holding the vehicle at a
stop and there is another vehicle
directly ahead, pressing RES+ will
increase the set speed. Pressing
RES+ when there is no longer a
vehicle ahead will cause ACC to
resume.
Reducing Speed While ACC Is at a
Set Speed
Do one of the following:
Use the brake to get to the desired
lower speed. Press SET and
release the accelerator pedal. The
vehicle will now cruise at the
lower speed.
Press and hold SET until the
desired lower speed is reached,
then release it.
To decrease speed in smaller
increments, press SET to the first
detent. For each press, the vehicle
goes about 1 km/h (1 mph) slower.
