GMC 15919282 Automobile User Manual


 
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. Re-install 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 tow
and then secure it to the
towing vehicle.
2. Shift the transmission to
P (Park) and turn the ignition
to LOCK/OFF.
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
50 amp BATT1 fuse from the
underhood fuse block and
store in a safe location.
See Underhood Fuse Block
on page 5-90.
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.
Notice: If 65 mph (105 km/h) is
exceeded while towing the
vehicle, it could be damaged.
Never exceed 65 mph (105 km/h)
while towing the vehicle.
Once the destination is reached:
1. Set the parking brake.
2. Reinstall the 50 amp BATT1 fuse
to 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.
