GMC Acadia 2012 Owner's Manual page 385

For vehicles being dinghy towed,
the vehicle should be run at the
beginning of each day and at each
RV fuel stop for about five minutes.
This will ensure proper lubrication of
transmission components. Reinstall
the fuse to start the vehicle.
To tow the vehicle from the front
with all four wheels on the ground:
1. Position the vehicle to be towed,
shift the transmission to
P (Park), and turn the ignition to
LOCK/OFF.
2. Secure the vehicle to the towing
vehicle.
3. Set the parking brake.
4. Turn the ignition to
ACC/ACCESSORY.
5. Shift the transmission to
N (Neutral).
6. To prevent the battery from
draining while the vehicle is
being towed, remove the 15 amp
ECM fuse and the 50 amp
BATT1 fuse from the underhood
fuse block and store in a safe
location. See Engine
Compartment Fuse Block on
page 10 30.
7. Release the parking brake.
Notice: If the vehicle is towed
without performing each of the
steps listed under Dinghy
Towing, the automatic
transmission could be damaged.
Be sure to follow all steps of the
dinghy towing procedure prior to
and after towing the vehicle.
Vehicle Care
Notice: If 105 km/h (65 mph) is
exceeded while towing the
vehicle, it could be damaged.
Never exceed 105 km/h (65 mph)
while towing the vehicle.
Once the destination is reached:
1. Set the parking brake.
2. Reinstall the fuses in the
underhood fuse block.
3. Shift the transmission to
P (Park), turn the ignition to
LOCK/OFF and remove the key
from the ignition.
4. Disconnect the vehicle from the
towing vehicle.
Notice: Do not 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.
