7. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.

Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after
a time. The wheel could come
off and cause an accident. When
you change a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle. In an
emergency,
you can use a cloth or a paper towel
to do this; but be sure to use
a scraper or wire
brush later, if you need to, to get all the rust or
dirt off.

Never use oil or grease on studs or nuts. If you
do, the nuts might come loose.
Your wheel could
fall
off, causing a serious accident.
8. Place the spare on the wheel mounting surface.
9. Replace the wheel nuts
with the rounded end
of
the nuts toward the
wheel. Tighten each nut

Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become loose
and even come
off. This could lead to an accident.
Be sure to use the correct wheel nuts. If you have
to replace them, be sure to get the right kind.
Stop somewhere
as soon as you can and have the’
nuts tightened with
a torque wrench to 100 lb-ft
(140 N-m).
NOTICE:
Improperly tightened wheel nuts can lead to
brake pulsation and rotor damage.
To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque specification.
12. Then replace the wheel cover. Be sure to position
the alignment pin on the cover with the notch in the
wheel. Apply pressure around the edge of the cap to
snap
it in place.
Don’t
try to put the wheel cover on the compact
spare tire.
It won’t fit. Store the wheel cover in the
trunk until you have replaced the compact spare tire
with
a regular tire.
1 NOTICE:
Wheel covers won’t fit on your compact spare. If
you try to put a wheel cover on your compact
spare,
you could damage the cover or the spare.

Storing the Flat Tire and Tools
Storing a jack, a tire or other equipment in the
passenger compartment
of the vehicle could
cause injury. In
a sudden stop or collision, loose
equipment could strike someone. Store all these
in the proper place.
'I
Store the flat tire as far forward in the trunk as possible.
Store the jack and wheel wrench
in their compartment in
the trunk.

Storing the Spare Tire and Tools
The compact spare tire is for temporary use only.
Replace the compact spare tire with a full-size tire as
soon as you can. See “Compact Spare Tire” later in this
section. See the storage instructions label to replace your
compact spare into your trunk properly.
Compact Spare Tire
Although the compact spare tire was fully inflated when
your vehicle was new, it can lose air after a time. Check
the inflation pressure regularly. It should be
60 psi
(420 Pa).
After installing the compact spare on your vehicle, you
should stop as soon as possible and make sure your
spare tire is correctly inflated. The compact spare is
made to perform well at posted speed limits for
distances up to
3,000 miles (5 000 krn), so you can
finish your trip and have your full-size tire repaired or
replaced where you want. Of course, it’s best
to replace
your spare with a full-size tire as
soon as you can. Your
spare will
last longer and be in good shape in case you
need it again.
NOTICE: -
When the compact spare is installed, don’t take
your vehicle through an automatic car wash with
guide rails. The compact spare can get caught on
the rails. That can damage the tire and wheel,
and maybe other parts
of your vehicle.
ProCarManuals.com

Don’t use your compact spare on other vehicles.
And don’t mix your compact spare tire
or wheel with
other wheels or tires. They won’t fit. Keep your spare
tire and its wheel together.
ITICE:
~
Tire chains won’t fit your compact spare. Using
them can damage your vehicle and can damage
the chains too. Don’t use tire chains on your
compact spare.
If You’re Stuck: In Sand, Mud,
Ice or Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels too fast. The method known as
“rocking” can help you get out when you’re stuck, but
you must use caution.
If you let your tires spin at high speed, they can
explode, and you or others could be injured. And,
the transaxle or other parts
of the vehicle can
overheat. That could cause an engine
compartment fire or other damage. When you’re
stuck, spin the wheels
as little as possible. Don’t
spin the wheels above
35 mph (55 km/h) as shown
on the speedometer.
ProCarManuals.com

NOTICE:
Spinning your wheels can destroy parts of your
vehicle as well
as the tires. If you spin the wheels
too fast while shifting your transaxle back and
forth, you can destroy your transaxle.
For information about using tire chains on your vehicle,
see “Tire Chains” in the Index.
Rocking your vehicle to get it out:
First, turn your steering wheel left and right. That will
clear the area around your front wheels. You should turn
your traction control system off. (See “Traction Control
System” in the Index.) Then shift back and forth
between REVERSE
(R) and a forward gear, spinning the
wheels as little
as possible. Release the accelerator pedal
while you shift, and press lightly on the accelerator
pedal when the transaxle is in gear. If that doesn’t get
you out after
a few tries, you may need to be towed out.
If you do need to be towed out, see “Towing Your
Vehicle” in the Index.

An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing and tools away from any
underhood electric fan.

Things that burn can L on hot engine parts and
start
a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber.
You or others

things that will burn onto
a hot engine.

The following sections tell you how to check fluids,
lubricants and important parts underhood.
Hood Release
To open the hood, first pull
the hood release handle
inside the vehicle, located to

NOTICE:
a
a Using the wrong fluid can badly damage
brake system parts. For example, just
a few
drops of mineral-based oil, such
as engine
oil, in your brake system can damage brake
system parts
so badly that they’ll have to be
replaced. Don’t let someone put in the
wrong kind of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on your vehicle.
If you do, wash it off
immediately. See “Appearance Care” in
the Index.
Brake Wear
Your Aurora has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make a
high-pitched warning sound when the brake pads are worn
and new pads
are needed. The sound may come and go or
be heard all the time your vehicle is
moving (except when
you are pushing on
the brake pedal firmly).
The brake wear warning sound means that sooner
or later your brakes won’t work well. That could
lead to an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
ProCarManuals.com

Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(10
000 to 13 000 km) for any signs of unusual wear.
If unusual wear is present, rotate your tires as soon as
possible and check wheel alignment. Also check for
damaged tires or wheels. See “When It’s Time for New
Tires” and “Wheel Replacement” later in this section for
more information.
The purpose
of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See “Scheduled
Maintenance Services” in
the Index for scheduled
rotation intervals. When rotating your tires, always use the correct rotation
pattern shown here.
Don’t include the compact spare tire in your tire
rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire-Loading
Information label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque”
in the
Index.
Rust or dirt on
a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after
a time. The wheel could come off and cause
an accident. When you change
a wheel, remove
any rust or dirt from places where the wheel
attaches
to the vehicle. In an emergency, you can
use
a cloth or a paper towel to do this; but be
sure to use
a scraper or wire brush later, if you
need to, to get all the rust or dirt off. (See
“Changing
a Flat Tire” in the Index.)
