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.
