2004 - 2008 Cadillac XLR and XLR-V: TechLink Article: "Shift to Park" Message
On some 2004 - 2008 Cadillac XLR and V models, the Driver Information Center (DIC) may display a "Shift To Park" message when the vehicle is in Park, or the Auto Door Lock/Unlock features may be inoperative. Also, the ignition mode switch may not go to the Off position.
One of these may be the cause.
Adjust the shift cable in the Park position. Place the shifter in the Park position, lift the vehicle and rotate the rear wheels to verify that the park pawl is engaged (wheels will not move). Release the cable adjustment lock and allow the cable to relax. Re-seat the cable adjustment lock. Refer to SI document 927794 if needed to verify shift cable adjustment procedures.
Check the status of the Internal Mode Switch in the Transmission Control Module (TCM). If the TCM is indicating the correct gear, check the secondary park switch located on the right side of the shifter assembly. This switch is a direct input into the Body Control Module (BCM). This data can be viewed by following the Tech 2 path below.
If the secondary park switch shows Park via Tech 2 data, re-check the shift cable adjustment and make sure the shifter button is not stuck. If both items check OK, replace the shifter assembly. At present, the switch is not available separately.
