in NEUTRAL (N). If you have a
four-wheel-drive vehicle with a manual transfer case
shift lever, be sure
the transfer case is not in
NEUTRAL (Nj.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the ci, wsette
lighter, or accessory power outlets,

Engine Fan Noise If a Tire Goes Flat
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 fan will
slow down when additional cooling is not required and
the clutch disengages.
You
may also hear this fan noise when you start he
engine.
It will go away as the fan clutch disengages. 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 muc11 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 ~naintain 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 yo~~r foot from the
accelerator pedal. Get the c.ehicle under control
by
steering the way ~OLI 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.

Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your hazard
warning flashers.
A CAUTION:
Changing a tire can cause an injury. The vehicle
can slip off the jack and roll over you or other
people. You and they could be badly injured.
Find a level place to change your tire.
To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put an automatic transmission shift
lever in PARK
(P) or shift a manual
transmission to FIRST
(1) or
REVERSE (R).
CAUTIQN: iContinued) .~
3. If you have a four-wheel-drive vehicle
with a manual transfer case shift lever,
be sure the transfer case is in a drive
gear
-- not in NEUTRAL (N).
4. Turn off the engine.
5. Put the wheel blocks at the front and
rear
of the tire farthest away from the
one being changed. That would be the
tire on the other side of the vehicle,
at
the opposite end.
