9-54 Driving and Operating
Maintenance When Trailer
Towing
The vehicle needs service
more often when pulling a trailer.
See Maintenance Schedule on
page 11‑2. 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 10‑18.
Trailer Towing
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?
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.
Use the following chart to determine
how much the vehicle can weigh,
based upon the vehicle model and
options.
