Tilt Switch Operation

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2012 GMC Yukon XL, 2012 GMC Yukon, 2012 Chevrolet Tahoe, 2012 Chevrolet Suburban, and 2012 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The tilt steering column has a two-position switch which may be used to adjust the position of the steering wheel up or down which is tilt. The position of the column may be changed as follows:

Press the switch up to tilt the column up.
Press the switch down to tilt the column down.

The memory seat module (MSM) receives inputs from the tilt switch to manually move the column to a desired position. Pressing the control switch sends an input to the MSM. The MSM receives an input and actuates the corresponding column motor.

Pressing the switch momentarily in either the UP or DOWN and releasing within 0.5 seconds, causes the column to advance slightly in the corresponding direction then stop. This feature allows fine control of the steering column position in each direction. If the switch is pressed and held for longer than 0.5 seconds, the column advances slightly in that direction, pauses, then resumes movement as long as the switch is held.
