Once ACC is set, it may immediately apply the brakes if it detects a vehicle ahead is too close or moving slower than your vehicle. This symbol will appear on the Head-Up Display (HUD) to indicate that ACC is active. See Head-Up Display (HUD) on page 3-29 for more information. • Move the ACC switch from on to resume/increase. Hold it there until the desired set speed is displayed in the HUD, then release the switch. To increase your set speed in very small amounts, move the switch briefly to resume/increase. Each time you do this, your vehicle set speed will increase by 1 mph (1.6 km/h). Your vehicle will not reach the set speed until ACC determines there is no vehicle in front of you. At that point, your vehicle speed will increase to the set speed. Decreasing Set Speed While Using ACC Make sure the set speed is visible on the HUD so you know the speed your vehicle will accelerate to if no vehicle is detected in your path. Keep in mind speed limits, surrounding traffic speeds and weather conditions when adjusting your set speed. Press in the set/decrease button on the end of the lever until you reach the lower speed you want, then release it. To slow down in very small amounts, briefly press the set/decrease button. Each time you do this, your set speed will be 1 mph (1.6 km/h) slower. Increasing Set Speed While Using ACC There are two ways to go to increase set speed: Resuming a Set Speed Suppose you set your ACC at a desired speed and then you apply the brake. This will disengage the ACC. But you don't need to reset it. Once you are going about 25 mph (40 km/h) or more, you can move the ACC switch briefly from on to resume/increase. ACC will be engaged with the previously chosen set speed. • Use the accelerator to get to the higher speed. Press the set button at the end of the lever, then release the button and the accelerator pedal. You'll now cruise at the higher speed. 3-15
