From 2012 Terrain owner's manual:
To tow the vehicle from the front with all four wheels on the ground:
1. Position the vehicle that will be towed and secure it to the towing vehicle.
2. Turn the ignition key to ON/RUN.
3. Shift the transmission to N (Neutral).
4. Turn the ignition key to ACC/ ACCESSORY.
5. Turn all accessories off.
6. To prevent the battery from draining while the vehicle is being towed, remove fuse 32, the Discrete Logic Ignition Switch fuse, from the instrument panel fuse block and store it in a safe location.
