Chrysler 2008 300 SRT - Manual (Page 162)

To Vary the Speed Setting
While ACC is set, you can increase the set speed by lifting
and holding the lever in RESUME ACCEL. If the lever is
continually held, the set speed will continue to increase
in 5 mph (Canada 10 km/h) increments until the lever is
released. The increase in set speed is reflected in the EVIC
display.
Tapping the lever up once will result in a 1 mph (Canada
1 km/h) increase in set speed. Each subsequent tap of the
lever results in an increase of 1 mph (Canada 1 km/h).
While ACC is set, the set speed can be decreased by
pushing and holding the lever down in SET DECEL. If
the lever is continually held, the set speed will continue
to decrease in 5 mph (Canada 10 km/h) increments until
the lever is released. The decrease in set speed is reflected
in the EVIC display.
Tapping the lever down once will result in a 1 mph
(Canada 1 km/h) decrease in set speed. Each subsequent
tap of the lever results in a decrease of 1 mph (Canada 1
km/h).
NOTE:
• When you use the lever to decelerate, if the engine’s
braking power does not slow the vehicle sufficiently to
reach the set speed, the brake system will automati-
cally slow the vehicle.
• The ACC system maintains set speed when driving up
hill and down hill. However, a slight speed change on
moderate hills is normal. In addition, downshifting
may occur while climbing uphill or descending down-
hill. This is normal operation and necessary to main-
tain set speed.
