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.

9. Then fill the coolant recovery tank to the
FULL COLD mark.

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.

5-20
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.

The equipment you'll need is located in the storage
compartment at the rear of the vehicle, on the

Removing the Spare Tire (Vehicles without the
Rear Convenience/Cargo Tray)

2. Attach the folding wrench into the hoist shaft.
3. Turn the folding wrench counterclockwise to lower
the spare tire to the ground. Continue turning the
wrench until the spare tire can be pulled out from
under the vehicle.
4. To remove the spare tire from the cable, tilt the
retainer and slip it through the wheel opening.

5-23
5. After removing the spare tire, turn the wrench
clockwise to raise the cable back up.
Do not store a full
-size or a flat road tire under the
vehicle. See ªStoring a Flat or Spare Tire and Toolsº
later in this section.
To continue changing the flat tire see ªRemoving the Flat
Tire and Installing the Spare Tireº later in this section.
If the spare tire will not lower, the secondary latch may
be engaged and causing the tire not to lower.Do the following to check the cable:
1. Check under the vehicle to see if the cable is visible.
2. If not visible, see ªSecondary Latch Systemº
later in this section.
If visible, first try to tighten the cable by turning
the folding wrench clockwise until you hear two
clicks or feel it skip twice. You can not overtighten
the cable.
3. Loosen the cable by turning the wrench
counterclockwise three or four turns.
4. Repeat this procedure at least two times.
5. If you still cannot lower the spare tire to the ground,
see ªSecondary Latch Systemº later in this section.
6. If the spare tire did lower to the ground, continue with
Step 4 under ªRemoving the Spare Tire (Vehicles
