2010 GMC CANYON transmission

3. Turn the engine off and firmly set the parking brake.
SeeParking Brake on page 3-30.
4. Securely attach the vehicle being towed to the tow
vehicle.
{WARNING:
Shifting a full-time four-wheel-drive vehicle’s
transfer case into N (Neutral) can cause the
vehicle to roll even if the automatic transmission is
in P (Park) or the manual transmission is in any
gear. You or others could be injured. Make sure
the parking brake is firmly set before the transfer
case is shifted to N (Neutral).5. Shift the transfer case to N (Neutral). See “Shifting
into N (Neutral)” underFour-Wheel Drive on
page 3-25.
6. Turn the ignition to LOCK/OFF and remove the
key — the front wheels will still turn.
7. Release the parking brake only after the vehicle
being towed is firmly attached to the towing
vehicle.
After towing see “Shifting Out of N (Neutral)” under
Four-Wheel Drive on page 3-25.
If the vehicle being towed will not be started or driven
for six weeks or more, remove the battery cable from the
negative terminal (post) of the battery to prevent the
battery from draining.

Dolly Towing
Front Towing (Front Wheels Off the
Ground)
Two-Wheel-Drive Vehicles
Notice:If a two-wheel-drive vehicle is towed with
the rear wheels on the ground, the transmission
could be damaged. The repairs would not be
covered by the vehicle warranty. Never tow the
vehicle with the rear wheels on the ground.
Two-wheel-drive vehicles should not be towed with
the rear wheels on the ground. Two-wheel-drive
transmissions have no provisions for internal lubrication
while being towed.
To dolly tow a two-wheel-drive vehicle, the vehicle must
be towed with the rear wheels on the dolly. See
“Rear Towing (Rear Wheels Off the Ground)” later in
this section for more information.

Four-Wheel-Drive Vehicles
Use the following procedure to dolly tow a
four-wheel-drive vehicle from the front:
1. Attach the dolly to the tow vehicle following the
dolly manufacturer’s instructions.
2. Drive the front wheels onto the dolly.
3. Put an automatic transmission in P (Park) or a
manual transmission in 1 (First).
4. Turn the engine off and firmly set the parking brake.
SeeParking Brake on page 3-30.

Rear Towing (Rear Wheels Off the Ground)
Two-Wheel-Drive Vehicles
Use the following procedure to dolly tow a
two-wheel-drive vehicle from the rear:
1. Attach the dolly to the tow vehicle following the
dolly manufacturer’s instructions.
2. Drive the rear wheels onto the dolly.3. Firmly set the parking brake. SeeParking Brake on
page 3-30.
4. Put an automatic transmission in P (Park) or a
manual transmission in 1 (First).
5. Secure the vehicle to the dolly following the
manufacturer’s instructions.
6. Use an adequate clamping device designed for
towing to ensure that the front wheels are locked
into the straight position.
7. Turn the ignition to LOCK/OFF.
If the vehicle being towed will not be started or
driven for six weeks or more, remove the battery
cable from the negative terminal (post) of the battery
to prevent the battery from draining.

Pulling A Trailer
Here are some important points:
•There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
the rig will be legal, not only where you live but
also where you will be driving. A good source for
this information can be state or provincial police.
•Consider using a sway control. See “Hitches” later
in this section.
•Do not tow a trailer at all during the first 500 miles
(800 km) the new vehicle is driven. The engine,
axle or other parts could be damaged.
•Then, during the first 500 miles (800 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps
the engine and other parts of the vehicle wear in at
the heavier loads.
•Vehicles with automatic transmissions can tow in
D (Drive), but you may want to shift to a lower
gear selection if the transmission shifts too often
(e.g., under heavy loads and/or hilly conditions).
If the vehicle has a manual transmission it is better
not to use the highest gear.Three important considerations have to do with weight:
•The weight of the trailer
•The weight of the trailer tongue
•The weight on the vehicle’s tires
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how the rig is used. For example, speed,
altitude, road grades, outside temperature and how
much the vehicle is used to pull a trailer are all
important. It can depend on any special equipment on
the vehicle, and the amount of tongue weight the vehicle
can carry. See “Weight of the Trailer Tongue” later in
this section for more information.
Maximum trailer weight is calculated assuming only the
driver is in the tow vehicle and it has all the required
trailering equipment. The weight of additional optional
equipment, passengers and cargo in the tow vehicle
must be subtracted from the maximum trailer weight.
