Cruise Release Switch Adjustment

WARNING: This page is about a different car, the 2003 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.

Important: The cruise control release switch and the stop lamp switch are adjusted together. Incorrect adjustment of either of these switches may cause premature brake lining wear or the incorrect operation of the cruise control system.

Remove the left instrument panel insulator. Refer to CLOSEOUT/INSULATOR PANEL REPLACEMENT - LEFT in Instrument Panel, Gages and Console.

Press the brake pedal fully.
Push the switches into the retainers until the switches are fully seated.
Pull the brake pedal fully rearward against the pedal stop until the audible clicks can no longer be heard.
Measure the brake pedal travel distances from the centerline of the brake pedal pad. Compare the measurements to the following values. The comparison of the values can verify that the cruise control release switch and the stop lamp switch are correctly adjusted:
- The cruise control release switch and the stop lamp switch contacts must actuate at 3.5-12.5 mm (0.125-0.500 in) of brake pedal travel.
- Nominal actuation of the stop lamp switch contacts occurs about 4.5 mm (0.2 in) beyond the point of cruise control release switch actuation.
