Steering Wheel Switch Function

The ACC steering wheel mounted switches are momentary contact switches that toggle up and down for the cruise control switch state. Pressing and releasing the on (speedometer icon) switch turns the cruise control system on. Pressing SET+ and releasing the set switch sets the vehicle's speed and stores the set speed in memory. The ACC indicator illuminates and the message center displays the set speed and gap setting graphic.

There are two ways to change the set speed. The first way is to accelerate or brake to the desired speed and press and release the set cruise control switch until the desired set speed is shown on the message center. The second way is by tapping the SET+ or the SET- switch while in the set mode, increasing or decreasing the displayed set speed by 1.6 kmh (1 mph) per tap. If the respective button is pressed and held, the displayed set speed continues to increase or decrease until the button is released. The ACC system may apply the brakes to slow the vehicle down to the new set speed. The set speed displays continuously in the message center while the ACC system is active.

Pressing and releasing the off (speedometer icon) switch or switching the ignition to off, turns the ACC system off. The ACC set speed memory is erased.

Applying the brake pedal or pressing the CAN/RES switch puts the ACC system in standby mode and the last set speed is displayed in the message center with a strike-through. Pressing the RES switch when the ACC system is in standby mode causes the vehicle to accelerate to the last set speed. The set speed continuously displays in the message center while the ACC system is active. The resume (RES) switch does not function if the off switch is pressed, the ignition is cycled off or if the current vehicle speed is below the minimum operational speed.

The ACC system has the capability for the driver to change from ACC to standard cruise control. The steering wheel switches are used to switch from ACC to standard cruise control within the message center. For information on selecting the standard cruise control in the message center, refer to the Owner's Literature for additional information. Once the standard cruise control is selected in the message center, the ACC indicator is replaced by the standard cruise control indicator. The vehicle no longer responds to lead vehicles or automatic braking. Upon the next ignition cycle, the vehicle defaults back to the ACC system.
