Downloaded from www.Manualslib.com manuals search engine Parking on Hills
You really should not park your vehicle, with a trailer
attached,
on a hill. If something goes wrong, your rig
could start
to move. People can be injured, and both
your vehicle and
the trailer can be damaged.
But if you ever have
to park your rig on a hill, here’s
how to do
it:
1. Apply your regular brakes, but don’t shift into
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 regular brakes. Then apply your parking
brake, and shift to
PARK (P).
5. Release the regular brakes.
PARK (P) yet.
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while
you:
0 Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
:ks.
3. Drive slowly until the trailer is clear of the choc
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belt, cooling system
and brake adjustment. Each
of these is covered in this
manual, and the Index will help
you find them quickly.
If you’re trailering, it’s a good idea
to review these
sections before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.

This vehicle has a clutched engine cooling fan. When
the clutch is engaged, the fan spins faster to provide
more air to cool the engine. In most everyday driving
conditions, the clutch is not
fully engaged. This
improves fuel economy and reduces fan noise. Under
heavy vehicle loading, trailer towing andor high
outside temperatures, the fan speed increases when the
clutch engages.
So you may hear an increase in fan
noise. This is normal and should not be mistaken
as the
transmission slipping or making extra shifts. It is merely
the cooling system functioning properly. The fan will
slow down when additional cooling
is not required and
the clutch disengages.
You may also hear this fan noise when you start the
engine. It will go away
as the fan clutch disengages.
If a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re driving,
especially
if you maintain your tires properly. If air goes
out of
a tire, it’s much more likely to leak out slowly.
But
if you should ever have a “blowout,” here are a few
tips about what to expect and what
to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot off
the
accelerator pedal and grip the steering wheel firmly.
Steer
to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to
a stop -- well off the road if possible.
If
a tire goes flat, the next part shows how to use your
jacking equipment to change a flat tire safely.
