NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts. So
use the recommended coolant.
CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot
enough. Don't spill coolant on a hot engine.
1. You can remove the coolant surge tank pressure cap
when the cooling system, including the coolant surge
tank pressure cap and upper radiator hose, is no
longer hot. Turn the pressure cap slowly
counterclockwise (left) about two or two and
one
-half turns. If you hear a hiss, wait for that to
stop. This will allow any pressure still left to be
vented out the discharge hose; wait for that to stop.

2. Then keep turning the pressure cap slowly, and
remove it.3. Then fill the coolant surge tank with the proper
mixture, to the FULL COLD mark or just above the
small cylinder at the base of the opening.

4. With the coolant surge tank pressure cap off, start the
engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the engine
cooling fans.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower, add
more of the proper mixture to the coolant surge tank
until the level reaches the FULL COLD mark, or just
above the small cylinder at the base of the opening.5. Then replace the pressure cap. Be sure the pressure
cap is hand
-tight.
Check the level in the surge tank when the cooling
system has cooled down. If the coolant isn't at the
proper level, repeat Steps 1 to 3 and reinstall the
pressure cap or see your dealer.

If a Tire Goes Flat
It's unusual for a tire to ªblow outº 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 ªblowout,º 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.
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.
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 the shift lever in PARK (P).
3. Turn off the engine.
To be even more certain the vehicle won't move,
you can put 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.

The following steps will tell you how to use the jack and
change a tire.
Removing the Spare Tire and Tools
The equipment you'll need
is in the trunk. Pull the
carpeting from the floor of
the trunk. Turn the center
retainer nut on the
compact spare cover
counterclockwise to
remove it.
Lift and remove the cover. See ªCompact Spare Tireº
later in this section for more information about the
compact spare.

Turn the wing nut
counterclockwise and
remove it. Then lift off the
spacer and remove the
spare tire.
Remove the jack and wheel wrench from the trunk. Your
vehicle's jack and wheel wrench are stored in a foam
tray. Remove the band around the jack.
The tools you'll be using include the jack (A) and wheel
wrench (B).

5-21 Removing the Flat Tire and Installing the
Spare Tire
1. Remove the wheel nut caps (you may need to use the
wheel wrench to loosen and remove them, if your
fingers do not fit into this small area).
2. Then use the wheel wrench to loosen all the wheel
nuts. Don't remove them yet.
3. Position the jack and raise the jack head until it fits
firmly into the notch in the vehicle's frame nearest
the flat tire. Put the compact spare tire near you.

CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack, you
could be badly injured or killed. Never get under
a vehicle when it is supported only by a jack.
CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to fit the jack
lift head into the proper location before raising
the vehicle.4. Raise the vehicle by rotating the wheel wrench
clockwise. Raise the vehicle far enough off the
ground so there is enough room for the spare
tire to fit.
5. Remove all of the wheel nuts.
6. Remove the flat tire.
