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 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 922

Trailer Towing
(2.4L L4 Engine)
Vehicles with a four cylinder engine
are neither designed nor intended to
tow a trailer.
Trailer Towing (3.0L and
3.6L V6 Engines)
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 your
vehicle's tires.
Weight of the Trailer
How heavy can a trailer safely be?
For a vehicle with a V6 engine, it
should never weigh more than
454 kg (1,000 lbs). 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.
