8-62 Driving and Operating
Maintenance When Trailer
Towing
The vehicle needs service more
often when pulling a trailer.
See Maintenance Schedule on
page 10‑2. Things that are
especially important in trailer
operation are automatic
transmission fluid, 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. See Engine Overheating
on page 9‑22.
Trailer Towing
(CTS-V and Coupe)
The vehicle is neither designed nor
intended to tow a trailer.
Trailer Towing (Except
CTS-V and Coupe)
Before pulling a trailer, there are
three important considerations that
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?
Speed, altitude, road grades,
outside temperature, special
equipment, and the amount of
tongue weight the vehicle can carry
must be considered. 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 for our trailering
information or advice.
