Dolly Towing (Rear-Wheel-Drive
Vehicles)
Use the following procedure to dolly tow a
rear-wheel-drive vehicle from the rear:
1. Attach the dolly to the tow vehicle following the
dolly manufacturer’s instructions.
2. Put the rear wheels on the dolly.
3. Firmly set the parking brake. SeeParking Brake on
page 2-42.4. Put the vehicle in P (Park) for an automatic
transmission or in 1 (First) for a manual
transmission.
5. Securely attach the vehicle being towed to
the dolly.
6. Clamp the steering wheel in a straight-ahead
position with a clamping device designed for towing.
7. Turn the ignition to LOCK/OFF.
Dolly Towing (All-Wheel-Drive Vehicles)
Notice:Towing an all-wheel-drive vehicle with all
four wheels on the ground, or even with only two of
its wheels on the ground, will damage drivetrain
components. Do not tow an all-wheel-drive vehicle
with any of its wheels on the ground.
All-wheel-drive vehicles can only be towed with all four
wheels on a trailer.
Towing a Trailer (CTS-V)
The CTS-V is neither designed nor intended to tow a
trailer.

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.
Do not tow a trailer at all during the rst 1,000 miles
(1 600 km) the new vehicle is driven. The engine,
axle or other parts could be damaged.
Then, during the rst 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). Shift the transmission to a lower gear
if the transmission shifts too often under heavy
loads and/or hilly conditions. For vehicles with a
manual transmission, it is better not to use the
highest gear.
Obey speed limit restrictions when towing a trailer.
Do not drive faster than the maximum posted speed
for trailers, or no more than 55 mph (90 km/h), to
save wear on the vehicle’s parts.Three important considerations have to do with weight:
The weight of the trailer.
The weight of the trailer tongue.
The total weight on the vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 1,000 lbs (450 kg).
But even that can be too heavy.
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.
Ask your dealer/retailer for our trailering information
or advice, or write us at our Customer Assistance
Offices. SeeCustomer Assistance Offices on page 7-6
for more information.

Turn Signals When Towing a Trailer
The arrows on the instrument panel ash whenever
signaling a turn or lane change. Properly hooked up, the
trailer lamps also ash, telling other drivers the vehicle
is turning, changing lanes or stopping.
When towing a trailer, the arrows on the instrument
panel ash for turns even if the bulbs on the trailer are
burned out. For this reason you may think other
drivers are seeing the signal when they are not. It is
important to check occasionally to be sure the
trailer bulbs are still working.
The vehicle has bulb warning lights. When a trailer
lighting system is plugged into the vehicle’s lighting
system, its bulb warning lights may not let the driver
know if one of the lamps goes out. So, when the a trailer
lighting system plugged in, be sure to check the
vehicle and trailer lamps from time to time to be sure
they are all working. Once the trailer lamps are
disconnected, the bulb warning lights can again let the
driver know that one of the vehicle lamps is out.
Driving On Grades
Reduce speed and shift to a lower gearbeforestarting
down a long or steep downgrade. If the transmission is
not shifted down, the brakes might have to be used so
much that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce the
vehicle’s speed to around 45 mph (70 km/h) to reduce
the possibility of the engine and the transmission
overheating.
Vehicles can tow in D (Drive). Shift the transmission to
a lower gear if the transmission shifts too often under
heavy loads and/or hilly conditions. For vehicles with a
manual transmission, it is better not to use the
highest gear.
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a lower
temperature than at normal altitudes. If the engine is
turned off immediately after towing at high altitude
on steep uphill grades, the vehicle may show signs
similar to engine overheating. To avoid this, let
the engine run while parked, preferably on level ground,
with the automatic transmission in P (Park) or the
manual transmission in N (Neutral) for a few minutes
before turning the engine off. If the overheat warning
comes on, seeEngine Overheating on page 5-37.

Parking on Hills
{CAUTION:
Parking the vehicle on a hill with the trailer
attached can be dangerous. If something goes
wrong, the rig could start to move. People can be
injured, and both the vehicle and the trailer can
be damaged. When possible, always park the rig
on a at surface.
If parking the rig on a hill:
1. Press the brake pedal, but if the vehicle has an
automatic transmission, do not shift into P (Park)
yet. Turn the wheels into the curb if facing downhill
or into traffic if facing uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the brake pedal. For vehicles with an
automatic transmission, apply the parking brake and
shift into P (Park). For vehicles with a manual
transmission, apply the parking brake, place the
transmission in 1 (First) and turn the ignition to
OFF/LOCK.
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal while you:
Start the engine
Shift into a gear
Release the parking brake
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
The vehicle needs service more often when pulling a
trailer. See this manual’s Maintenance Schedule or Index
for more information. Things that are especially important
in trailer operation are automatic transmission uid,
engine oil, axle lubricant, belts, cooling system and brake
system. It is a good idea to inspect these before and
during the trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
The cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating on
page 5-37.
