CRUISE RELEASE SWITCH ADJUSTMENT
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.

1. Remove the left instrument panel insulator.

2. Press the brake pedal fully.
3. Push the switches into the retainers until the switches are fully seated.
4. Pull the brake pedal fully rearward against the pedal stop until the audible clicks can no longer be heard.
5. 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.
6. Install the left instrument panel insulator.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
