Summary
14541 - CUSTOMER SATISFACTION. IF CERTAIN VEHICLES ARE DINGHY TOWED, THEIR TRANSFER CASE MAY BECOME LOCKED IN NEUTRAL WHEN PREPARING TO DISCONNECT THE VEHICLE ACCORDING TO THE PROCEDURES IN THE OWNER MANUAL. SPECIFICALLY, WHEN THE CUSTOMER CONNECTS THE BATTERY AND STARTS THE VEHICLE AS PART OF THE “DISCONNECTING THE TOWED VEHICLE” PROCEDURE (SEE OWNER MANUAL AT STEPS 3, 4, AND 5 OF THE “DINGHY TOWING”), A CODE IS SET THAT LOCKS THE VEHICLE’S TRANSFER CASE IN NEUTRAL. WHEN THIS OCCURS, THE DRIVER’S INFORMATION CENTER PANEL WILL DISPLAY A “SERVICE 4WD” MESSAGE AND THE VEHICLE WILL NEED TO BE TOWED TO A DEALERSHIP TO HAVE THE CODE CLEARED. DEALERS ARE TO PLACE A COPY OF AN UPDATED DINGHY TOWING SUPPLEMENT IN THE OWNER MANUAL. THIS INFORMATION REPLACES THE INFORMATION LOCATED UNDER “RECREATIONAL VEHICLE TOWING” FOUND IN SECTION 10 OF THE OWNER MANUAL. GM WILL MAIL THE SUPPLEMENT TO CUSTOMERS OF RECORD.
