The Speed Control buttons (located on the right
side of the steering wheel) operate the ACC
system.

Any chassis/suspension or tire size modifica-
tions to the vehicle will affect the performance
of the Adaptive Cruise Control and Forward
Collision Warning System.
Activating Adaptive Cruise Control (ACC)
You can only engage ACC if the vehicle speed is
above 0 mph (0 km/h).
The minimum set speed for the ACC system is
20 mph (32 km/h).
When the system is turned on and in the ready
state, the instrument cluster displays “ACC
Ready.”
When the system is off, the instrument cluster
displays “Adaptive Cruise Control (ACC) Off.”
