can add the proper coolant mix directly to the radiator, but be sure the
cooling
system is cool before you do it.
I CAUTION

A
Steam and scalding liquids from a hot cooling system can blow out
and burn you badly. They are under pressure, and
if you turn the
radiator pressure cap-even a little-they can come out at high
speed. Never
turn the pressure cap when the cooling system,
including the radiator pressure cap, is hot. Wait
for the cooling
system and radiator pressure cap
to cool if you ever have to turn
the pressure cap.

How to Add Coolant to the Radiator

1. You can remove the radiator pressure cap when the cooling system,
including the radiator pressure cap
and upper radiator hose, is no longer
hot. Turn the pressure cap slowly to the left until it
first stops. (Don't
press down while turning the pressure cap.)
If YOU hear a hiss, wait for that to stop. A hiss means there is Still SOt-t~e
pressure left.
2. Then keep turning the pressure cap, but now push down as you turn it.

Engine Fan Noise
This vehicle has a clutched engine cooling fan. When the clutc\
h is engaged,
the fan spins faster
to provide more air to cool the engine. In most every day
driving conditions, the clutch is not engaged. This improves fu\
el economy and
reduces fan noise. Under heavy vehicle loading, trailer towing \
andlor high
outside temperatures, the fan speed increases when the clutch e\
ngages.
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 whe\
n 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 Tim 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, 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 co\
ntrol 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 your tire goes flat, the next part shows how to use your jacking equipment
to change a flat tire safely.

If a tire goes flat, avoid further tire and wheel damage by driving slowly to a
level place. Turn on your hazard warning flashers.
I CAUTION
4
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 the shift lever in P (Park).
3. Turn off the engine.
To be even more certain the vehicle won’t move, you can put chocks
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.

Attach the ratchet, with the DOWN side facing you, to the extension. The
extension has a socket end and a flat (screwdriver shaped) end. Put the flat
end of the extension on an angle through the hole in the rear door \
frame,
above the bumper. Be sure the flat end connects into the hoist shaft.
Turn the ratchet counterclockwise to lower the spare tire to t\
he ground. Keep
turning the ratchet until the spare tire can be pulled out from under the
vehicle.
