To Turn Off
The system will turn off and clear the set speed
in memory if:
The Adaptive Cruise Control (ACC) on/off

button is pushed

To Resume
If there is a set speed in memory, push the RES
(resume) button and then remove your foot
from the accelerator pedal. The instrument
cluster display will display the last set speed.
Resume can be used at any speed above
20 mph (32 km/h) when only Fixed Speed
Cruise Control is being used.
Resume can be used at any speed above 0 mph
(0 km/h) when ACC is active.
NOTE:
While in ACC mode when the vehicle comes

to a complete stop longer than two seconds,
the system will cancel. The driver will have to
apply the brakes to keep the vehicle at a
standstill.
ACC cannot be resumed if there is a

stationary vehicle in front of your vehicle in
close proximity.
WARNING!
The Resume function should only be used if
traffic and road conditions permit. Resuming
a set speed that is too high or too low for
prevailing traffic and road conditions could
cause the vehicle to accelerate or decelerate
too sharply for safe operation. Failure to
follow these warnings can result in a collision
and death or serious personal injury.
