Maintenance when Trailer
Towing
The vehicle needs service more
often when pulling a trailer. See
the Maintenance Schedule for
more information. Things that
are especially important in trailer
operation are automatic
transmission fluid, engine oil,
axle lubricant, belts, cooling system
and brake system. 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 10 ‑ 24 .
Trailer Towing
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?
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.
