To Vary The Speed Setting
While ACC is set, you can increase the set speed by pressing and holding the RES + button. If the button is continually pressed, the set speed will continue to increase in 5 mph (8 km/h) increments until the button is released. The increase in set speed is reflected in the EVIC display.
Pressing the RES + button once will result in a 1 mph (1.6 km/h) increase in set speed. Each subsequent tap of the button results in an increase of 1 mph (1.6 km/h).
While ACC is set, the set speed can be decreased by pressing and holding the SET - button. If the button is continually pressed, the set speed will continue to decrease in 5 mph (8 km/h) increments until the button is released. The decrease in set speed is reflected in the EVIC display.
Pressing the SET - button once will result in a 1 mph (1.6 km/h) decrease in set speed. Each subsequent tap of the button results in a decrease of 1 mph (1.6 km/h).
NOTE:
• When you use the SET - button to decelerate, if the
engine’s braking power does not slow the vehicle
sufficiently to reach the set speed, the brake system
will automatically 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 downhill.
This is normal operation and necessary to maintain set speed.
