The purpose of this bulletin is to inform dealers of special procedures necessary when towing a trailer or when towing the vehicle behind a recreational vehicle. Towing a Trailer Trailer Weight Information The following chart shows how much the trailer can weigh, based on the vehicle powertrain combination and whether the vehicle is equipped with Trailer Provision (RPO V92). Retailers should refer customers to the appropriate Owner Manual for important trailering tips, vehicle maintenance, and safety rules before towing a trailer.

Page 2 June,2016 Important: The following modifications are intended to address the ability to update a vehicle to allow the electrical function for trailer lighting when trailer towing is desired only. Modification of a non-V92 vehicle to bring it up to the towing capacity of a V92 equipped vehicle is not practical or recommended. The V92 package when ordered as part of the original build of the vehicle includes additional cooling capability, engine and transmission calibrations to include a Tow/ Haul mode, which are not available for retrofit. The towing capability will remain at the non-V92 limits, even after the recommended electrical updates included in this bulletin to allow trailer lighting to function. Towing a Trailer with a Vehicle without Trailer Provisions (RPO V92) (2007 Model Year Only) These vehicles must be modified by installing a new underhood bussed electrical center (UBEC) to provide full functionality for 4 circuits: ground, tail lamps, RH and LH stop/turn lamps. Perform this modification only if the customers will be using the vehicle to tow. The replacement of the UBEC remains the best solution to upgrade the vehicles wiring for towing. The electrical circuitry for the tail/stop lamps is controlled by the BCM and splicing into the body harness is not recommended. The backup lamp circuit will also need to be modified using the following procedure: 1. Disconnect the X7 connector from the Body Control Module (BCM). 2. Remove the terminal for pin 3 from the BCM X7 connector. The wire to this terminal is dark blue and is the 38 circuit. Bulletin No.: 07-00-89-021Q 3. Re-connect the X7 connector to the BCM. 4. Cut the terminal off the end of this wire and strip the end of the wire. 5. Splice this wire into the 24 circuit wire that goes into BCM connector X6, pin 2. The 24 circuit is light green. Towing a Trailer with a Vehicle without Trailer Provisions (RPO V92) (2008-2012 Model Year Built Prior to May 01, 2012) These vehicles must be modified by installing a new underhood bussed electrical center (UBEC) to provide full functionality for 4 circuits: ground, tail lamps, RH and LH stop/turn lamps. Perform this modification only if the customers will be using the vehicle to tow. The replacement of the UBEC remains the best solution to upgrade the vehicles wiring for towing. The electrical circuitry for the tail/stop lamps is controlled by the BCM and splicing into the body harness is not recommended. Towing a Trailer with a Vehicle without Trailer Provisions (RPO V92) (2012-2017 Model Year Built After April 30, 2012) These vehicles must be modified by installing the necessary relays and fuses into the underhood bussed electrical center (UBEC) to provide full functionality for 4 circuits: ground, tail lamps, RH and LH stop/turn lamps. Refer to the illustration below for relay and fuse locations. Perform this modification only if the customers will be using the vehicle to tow.

Recreational vehicle towing means towing the vehicle behind another vehicle - such as behind a motorhome. The two most common types of recreational vehicle towing are known as "dinghy towing" (towing the vehicle with all four wheels on the ground) and "dolly towing" (towing the vehicle with two wheels on the ground and two wheels up on a device known as a "dolly"). With the proper preparation and equipment, many vehicles can be towed in these ways. Refer to the appropriate model/model year Owner Manual for towing preparation guidelines and dolly and dinghy towing procedures. The Towing Chart below summarizes powertrain combination compatibility with dolly and dinghy towing methods. Recreational Vehicle Towing Chart Powertrain Combination and Towing Method Rear Wheels on a Tow Dolly Front Wheels on a Tow Dolly All Four Wheels on the 3.6L V6 Engine with Front-Wheel Drive and 6T75 Six-Speed Automatic Transaxle (MY9) No Yes Yes* 3.6L V6 Engine with All-Wheel Drive and 6T75 Six-Speed Automatic Transaxle (MH6) No** No** Yes* *Caution: These vehicle can be dinghy towed from the front for unlimited miles at 65 mph (105 km/h). To avoid vehicle damage, never exceed 65 mph (105 km/h) while towing these vehicles. The repairs would not be covered by the warranty. **Caution: Dolly towing an all-wheel drive vehicle may result in premature failure of the rear drive module. Ground (Dinghy) Dinghy Towing Procedure (2007-2008 Model Year) Caution: If you tow your vehicle without performing each of the steps listed under "Dinghy Towing," you could damage the automatic transmission. Be sure to follow all steps of the dinghy towing procedure prior to and after towing your vehicle. Caution: Don't tow a vehicle with the front drive wheels on the ground if one of the front tires is a compact spare tire. Towing with two different tire sizes on the front of the vehicle can cause severe damage to the transmission.

GM bulletins are intended for use by professional technicians, NOT a "do-it-xourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide mformat1on that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition.
