Changing the set speed
There are three ways to change the set speed:
• Accelerate or brake to the desired speed and press SET upward and
release.
• Increase or decrease the speed by holding SET upward or downward
until the desired set speed is shown on the message center. The
vehicle speed will gradually change to the selected speed.
• Increase or decrease the speed in increments of 1 mph (2 km/h) by
briefly pressing the SET upward or downward.
The ACC may apply the brakes to slow the vehicle down to the new set
speed. The set speed will display continuously in the message center
while ACC is active.
Resuming the set speed
Press and release RES/CNCL. This will automatically return the vehicle
to the previously set speed. The set speed will display continuously in
the message center while ACC is active.
Note: Resume should only be used if the driver is aware of the set speed
and intends to return to it.
Low speed automatic cancellation
ACC is not functional at vehicle speeds below 16 mph (26 km/h). Once
the vehicle speed drops below 16 mph (26 km/h), an audible alarm will
sound and the automatic braking will be released.
Hilly condition usage
It is recommended that the driver select a lower gear position when ACC
is active in situations such as prolonged downhill driving on steep grades
(i.e., driving in mountainous areas). In these situations, additional engine
braking is needed to reduce the load on the vehicle’s regular brake
system to prevent them from overheating. For more information,
reference Automatic transmission operation in the Driving chapter.
Note: If ACC is applying brakes for an extended period of time, an
audible alarm will sound and ACC will shut down. This is to allow the
brakes to cool down. When the brakes have cooled down, the ACC will
again function normally.
Turning off cruise control
Press OFF to turn off the cruise control.
Note: When you turn off the cruise control or the ignition, your cruise
control set speed memory is erased.
