Chrysler 2010 300 - Owner Manual - Manual (Page 170)

While ACC is set, the set speed can be decreased by
pushing and holding the lever down (SET/DECEL). If
the lever is continually held, the set speed will continue
to decrease in 5 mph (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
(1 km/h) decrease in set speed. Each subsequent tap of
the lever results in a decrease of 1 mph (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 can only apply a maximum of 25% of
the vehicle’s braking capability and will not bring the
vehicle to a complete stop.
• 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.
