Increasing Speed While ACC is at a Set Speed

If ACC is already activated, do one of the following:

.Use the accelerator to get to the higher speed. Press SET– down. Release the control and the accelerator pedal. The vehicle will now cruise at the higher speed.

When the accelerator pedal is pressed, ACC will not brake because it is overridden.

A warning message will appear on the Driver Information Center (DIC) and Head-Up Display (HUD). See Cruise Control Messages on page 5-37.

.Press and hold +RES up until the desired set speed appears on the display, then release it.

.To increase vehicle speed in small increments, press +RES up to the first detent. For each press, the vehicle goes 1 km/h (1 mph) faster.

.To increase vehicle speed in larger increments, press +RES up to the second detent. For each press, the vehicle speed increases to the next 5 km/h (5 mph) mark on the speedometer.

When it is determined that there is no vehicle ahead or the vehicle ahead is beyond the selected following gap, then the vehicle speed will increase to the set speed.

The speedometer reading can be displayed in either English or metric units. See Instrument Cluster on page 5-9. The increment value used depends on the units displayed.
