Be mindful of speed limits, surrounding
traffic speeds, and weather conditions when
selecting the set speed.
Resuming a Set Speed
If the 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, pressRES+ up
briefly.
If the vehicle is travelling at more than
5 km/h (3 mph), 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 instrument cluster. 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
If ACC is already activated, do one of the
following:
Use the accelerator to get to the higher
speed. Briefly press and release 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. While overridden, the ACC
indicator will turn blue on the instrument
cluster and the head-up display,
if equipped.
Press and hold RES+ until the desired set
speed is displayed, then release it.
To increase speed in small increments,
pressRES+ 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.
Driving and Operating
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 or the vehicle ahead is
pulling away and the brake is not applied
will cause the ACC to resume.
When it is determined that there is no
vehicle ahead or the vehicle ahead is beyond
the selected following gap, then the vehicle
speed will increase to the set speed.
The speedometer reading can be displayed
in either English or metric units. See
Instrument Cluster 0 91. The increment value
used depends on the units displayed.
Reducing Speed While ACC is at a Set Speed
If ACC is already activated, do one of the
following:
Use the brake to get to the desired lower
speed. Release the brake and press SET .
The vehicle will now cruise at the lower
speed.
Press and hold SET until the desired
lower speed is reached, then release it.
