3. Fill the radiator with the proper DEX-COOL

coolant mixture, up to the base of the filler neck. See
ªEngine Coolantº in the Index for more information
about the proper coolant mixture.
4. Then fill the coolant
recovery tank to the
FULL COLD mark.
5. Put the cap back on the coolant recovery tank, but
leave the radiator pressure cap off.

6. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine cooling fans.
7. By this time, the coolant level inside the radiator
filler neck may be lower. If the level is lower, add
more of the proper DEX
-COOL
coolant mixture
through the filler neck until the level reaches the
base of the filler neck.8. Then replace the pressure cap. At any time during
this procedure if coolant begins to flow out of the
filler neck, reinstall the pressure cap.
Be sure the arrows on
the pressure cap line
up like this.

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.
1. Pull the carpeting from the floor of the trunk.
2. Lift and remove the cover.
3. Remove the spare tire. See ªCompact Spare Tireº
later in this section for more information about the
compact spare.

5-20
4. Unscrew the wing nuts to remove the container that
holds the wrench and jack.
5. Remove the wheel wrench, jack and the spare tire
from the trunk.
The tools you'll be using include the jack (A) and the
wheel wrench (B).
Removing Wheel Covers and Wheel
Nut Caps
1. If your vehicle has an aluminum wheel with a center
cover that hides the wheel nuts, remove the center
cover by using the flat end of the wheel wrench to
pry it off.
If your vehicle has a wheel cover, remove it by using
the flat end of the wheel wrench.
Pry along the edge of the wheel cover until it comes off.

5-21
2. If your vehicle has this
aluminum wheel, it may
have plastic wheel nut
caps. Use the wheel nut
wrench to remove the
wheel nut caps and to
loosen the wheel nuts.
3. When reinstalling the decorative nut caps, tighten the
caps snugly with the wheel wrench, then continue
one
-quarter turn to secure plastic caps.
When reinstalling the wheel cover, carefully line up the
tire valve stem and the notch in the wheel cover.
Removing the Flat Tire and Installing the
Spare Tire
1. Use the wheel wrench to loosen the wheel nuts, but
don't remove them yet.
2. The jack has a bolt at the end. Attach the wheel
wrench to the bolt to create a jack handle.

5-22
3. Turn the wheel wrench counterclockwise to lower
the jack head until it fits under the vehicle.
4. Put the jack into a notch in the frame which is
located near each wheel well. The front notch is
eight inches (20 cm) back from the front wheel well.
The rear notch is three inches (8 cm) forward from
the rear wheel well. The notches are accessible
through openings in the plastic trim at the bottom of
the vehicle.
Position the jack and raise the jack head until it fits
firmly on the ridge in the vehicle's frame nearest the
flat tire. Do not raise the vehicle yet. Put the compact
spare tire near you.

5-23
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.5. Raise the vehicle by turning the wheel wrench
clockwise in the jack. Raise the vehicle far enough
so there's enough room for the spare tire to fit under
the wheel well.
6. Remove all the wheel nuts and take off the flat tire.
