Housing Bypass Tube
3. After the engine cools, open the coolant air
bleed valves.
There are two bleed valves. One is located on the
thermostat housing. The other is located on the
thermostat bypass tube.
4. 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.
If you see a stream of coolant coming from an air
bleed valve, close the valve. Otherwise, close the
valves after the radiator is filled.
5. Rinse or wipe any spilled coolant from the engine
and the compartment.

5-19
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.

5-20
9. Then fill the coolant recovery tank to the FULL
COLD mark.
10. Put the cap back on the coolant recovery tank.
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.

5-21
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.

5-22 Removing the Spare Tire and Tools
The tools you'll need are
located in the storage
compartment at the rear of
the vehicle, on the
passenger's side.
To remove the tools, do the following:
1. Remove the side convenience net.
2. Open the jack storage compartment by lifting up the
tab and pulling the cover off.
A. Jack
B. Strap
C. Bracket
D. Wing NutE. Jacking Instructions
F. Bag and Tools
G. Tire Bag and Cable
(AWD only)
3. Remove the jack and jacking tools by loosening the
wing nut and bracket.
4. Separate the plastic pouch from the jack and remove
the jacking tools (folding wrench and extension)
from the pouch.

5-23
The tools you'll be using include the jack (A),
extension (B) and folding wrench (C).
The compact spare tire is located under the vehicle,
ahead of the rear bumper. See ªCompact Spare Tireº
later in this section for more information about the
compact spare. To remove the compact spare tire,
do the following:A. Hoist Shaft
B. Hoist Assembly
C. Retainer
D. Compact Spare TireE. Extension
(Chisel End)
F. Folding Wrench
1. Attach the folding wrench to the extension and insert
the chisel end on an angle through the hole in the
rear bumper and into the hoist shaft.
2. Turn the folding wrench counterclockwise to lower
the spare tire to the ground. Continue to turn the
wrench so the compact spare tire can be pulled out
from under the vehicle.

5-24
3. To remove the compact spare tire from the cable, tilt
the retainer at the end of the cable so it can be pulled
up through the wheel opening.4. If your vehicle is an all
-wheel-drive vehicle, after
removing the compact spare tire turn the wrench
clockwise to raise the cable back up.
On and AWD vehicle, you can not store a full
-size
tire under the vehicle. It should be stowed inside
the vehicle by the cable provided. See ªStoring the
Flat Tire on an All
-Wheel-Drive Vehicleº later in
this section.
If you have a front
-wheel-drive vehicle, the hoist is
used to store a full
-size or a flat road tire under the
vehicle. See ªStoring the Spare Tire and Toolsº and
ªStoring the Flat Tire on a Front
-Wheel-Drive
Vehicleº later in this section.
If the compact spare tire will not lower, check under the
vehicle to see if the tire is hanging loose and the cable
end and spring under the wheel plate are missing. If so
the secondary latch system is engaged. See ªSecondary
Latch Systemº later in this section.
To continue changing the flat tire see ªRemoving
the Flat Tire and Installing the Spare Tireº later in
this section.

5-25 Removing the Wheel Covers
If your vehicle has
aluminum wheels, use the
handle of the folding
wrench to pry the large
center cap.
Then, with the other end of the folding wrench, loosen
the nuts.
If your vehicle has the plastic ªbolt-onº wheel covers,
loosen the bolts completely using the folding wrench,
and remove the wheel cover.

5-26 Secondary Latch System (If Equipped)
Your vehicle may have an underbody mounted tire hoist
assembly equipped with a secondary latch system. It's
designed to stop a tire from suddenly falling off your
vehicle if the cable holding the spare tire is damaged.
For the secondary latch to work, the tire must be stowed
with the valve stem pointing down.
Front
-wheel-drive vehicles use the underbody tire hoist
assembly to store either the compact spare or a flat road
tire. See ªStoring a Flat or Spare Tire and Toolsº in the
Index for instruction on storing the spare or flat
tire correctly.
If your vehicle is equipped with all
-wheel-drive, the
underbody tire hoist assembly stores only the compact
spare tire. See ªStoring the Spare Tire and Toolsº in the
Index for instructions. To store a flat full±size tire
correctly, see ªStoring the Flat Tire on an
All
-Wheel-Drive Vehicleº in the Index.
CAUTION:
Before beginning this procedure read all the
instructions. Failure to read and follow the
instructions could damage the hoist assembly and
you and others could get hurt. Read and follow
the instructions listed below.
To release the spare tire from the secondary latch, do
the following:
CAUTION:
Someone standing too close during the procedure
could be injured by the jack. If the spare tire does
not slide off the jack completely, make sure no
one is behind you or on either side of you as you
pull the jack out from under the spare.

5-27
1. Place the jack under the vehicle, ahead of the rear
bumper. Position the center lift point of the jack
under the center of the compact spare tire.
2. Turn the folding wrench clockwise to raise the jack
until it lifts the secondary latch devise under the
wheel plate.
3. Keep raising the jack until the compact spare tire
stops moving upward and is held firmly in place, this
lets you know that the secondary latch has released.
4. Lower the jack by turning the folding wrench
counterclockwise. Keep lowering the jack until the
compact spare tire is resting on the folding wrench.5. Grasp the compact spare tire with both hands and
pull it out from under the vehicle.
6. Reach under the vehicle and remove the folding
wrench and jack.
Have the hoist assembly inspected as soon as you can.
You will not be able to store a spare or flat tire using the
hoist assembly until it has been repaired or replaced.
