Engine Fan Noise
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 engaged. This improves
fuel economy and reduces fan noise. Under heavy
vehicle loading, trailer towing and/or 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 fa11 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. I f air goes
o u t of a tire,
it's
much Inore likely to leak out slowly.
But
if you should ever have
; I
"blowout." here are a few
tips
about what to expect and what
to do:
If
a
front tire fails. the flat tire w i l l 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. I n any rear blowout. remove your foot from the
xcelerator pedal.
Get the
\,chicle
under
control by
steering the
way
you want
the
vehicle to go.
It
may be
\.cry
bunlpy and noisy.
but
you can still steer. Gently
brake to
a
stop -- well
off
the road if possible.
