10. Remove the lug nuts by turning them
counterclockwise, then remove the
wheel.
11. Mount the spare tire into position and
tighten the nuts by hand. Install the
lug nuts with the beveled edge
inward.
12. Turn the jack handle counterclockwise
and lower the vehicle until it touches
the ground.
Tighten the lug nuts firmly in an “X”
pattern.Once the lug nuts have been tightened,
lower the vehicle fully to the ground and
continue to tighten the lug nuts until they
are completely secured.
If you are unsure of the tightness of the
wheel lug nuts, have them checked at the
nearest service station. The specified
tightening torque is 76 ft. lb (103 N·m).

CAUTION
Your vehicle has metric threads on
the wheel studs and nuts. During
wheel removal, make certain that
the same nuts removed are
reinstalled - or, if replaced, that
nuts with metric threads and the
same configuration are used.
Installation of a non-metric thread
nut on a metric stud or vice-versa
will not secure the wheel to the hub
properly and will damage the stud
so that it must be replaced. Note
that most U.S. lug nuts do not have
metric threads. Be sure to use
extreme care in checking for thread
style before installing aftermarket
lug nuts or wheels. If in doubt,
consult an Authorized Kia Dealer.
Damaged studs may result in wheel
loss and personal injury.

6-25 To prevent the jack, jack handle, wheel
lug nut, wrench and spare tire from
rattling while the vehicle is in motion,
store them properly.
✻
NOTICE
Check the inflation pressures as
soon as possible after installing the
spare tire. Adjust it to the specified
pressure, if necessary.
Standard Tire : 210 kPa(30 psi)
Compact Spare Tire : 420 kPa(60
psi)
WARNING - Wheel Studs
If the studs are damaged, they
may lose their ability to retain
the wheel. This could lead to
the loss of the wheel and a
collision.

TIRES AND WHEELSTIRE CAREFor proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within the
load limits and weight distribution
recommended for your vehicle.INFLATION PRESSURESCheck all tire pressures (including the
spare) monthly when the tires are cold.
“Cold tires” means the car has not been
driven for at least three hours or driven
less than one mile (1.6 km).
Recommended pressures must be
maintained to ensure ride quality, vehicle
handling, and minimum tire wear.
Watch the battery during
charging, and stop or reduce
the charging rate if the battery
cells begin gasing (boiling)
violently or if the temperature
of the electrolyte of any cell
exceeds 120°F (49°C).
Wear eye protection when
checking the battery during
charging.
Disconnect the battery
charger in the following
order.
1. Turn off the battery
charger main switch.
2. Unhook the negative
clamp from the negative
battery terminal.
3. Unhook the positive clamp
from the positive battery
terminal.
✻
NOTICE
• Before performing battery
maintenance or recharging, turn
OFF all accessories and stop the
engine.
• When remounted battery,
disconnect the negative (-)
battery cable first. When re-
installing the battery, reconnect
the negative (-) battery cable
last.
MS-CNA-Eng 7.QXD 7/25/2005 5:09 PM Page 25

This can be found on the driver side
door.
The correct tire pressure is 210 kPa (30
psi). The compact spare should be at
420kPa (60 psi).

✻
NOTICE
• Warm tires normally exceed
recommended cold tire
pressures by 28 to 41 kPa(4 to 6
psi). Do not release air from
warm tires to adjust the
pressure. The tires will become
underinflated when cold.
• Underinflation results in
excessive wear, poor handling,
reduced fuel economy, and the
possibility of blowouts from
overheated tires. Also, low tire
pressure can cause poor sealing
of the tire bead. If the tire
pressure is excessively low,
wheel deformation and/or tire
separation are possible.
Keep tire pressures at the
proper levels. If a tire frequently
needs refilling, have it checked
by an Authorized Kia Dealer or
a tire shop.
• Overinflation produces a harsh
ride, handling problems,
excessive wear at the center of
the tire tread, and a greater
possibility of damage from road
hazards.
WARNING -
Tire Inflation
Overinflation or underinflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure. This
could result in loss of vehicle
control.
MS-CNA-Eng 7.QXD 7/25/2005 5:09 PM Page 26

7-27
TIRE ROTATIONTo equalize tread wear, it is
recommended that the tires be rotated
every 12,000km (7,500 miles) or sooner
if irregular wear develops.
During tire rotation, check the tires for
correct balance.
Check for uneven wear and damage.
Abnormal wear is usually caused by
incorrect tire pressure, improper wheel
alignment, an out-of-balance condition,
severe braking or severe cornering.Look for bumps or bulges in the tread or
side of tire. Replace the tire if you find
either of these conditions. Also, replace
the tire if you can see fabric or cord.
After rotation, be sure to bring the front
and rear tire pressures to specification
and check lug nut tightness.
Disc brake pads should be inspected for
wear whenever tires are rotated.
TIRE REPLACEMENTIf the tire is worn evenly, a tread wear
indicator will appear as a solid band,
12.7mm wide (1/2 inch) across the
tread. This shows there is less than
1.6mm (1/16 inch) of tread remaining on
the tire. Replace the tire when this
happens.
Do not wait for this band to appear
across the entire tread before replacing
the tire.

MAINTENANCE
7-28COMPACT SPARE TIRE
REPLACEMENTA compact spare tire has a shorter tread
life than a regular size tire. Replace it
when you can see the tread wear indicator
bars on the tire. The replacement compact
spare tire should be the same size and
design tire as the one provided with your
new Kia and should be mounted on the
same compact spare tire wheel. The
compact spare tire is not designed to be
mounted on a regular size wheel, and the
compact spare tire wheel is not designed
for mounting a regular size tire.
WHEEL ALIGNMENT AND
TIRE BALANCEIn addition to proper tire inflation,
correct wheel alignment helps to
minmize tire wear. Your vehicle’s
alignment should be checked every 12
months or 24,000 km (15,000 miles).
Your tires were properly balanced at the
factory, but they may need to be
rebalanced before they wear out. If you
notice a consistent vibration when
driving, have your Kia Dealer inspect
your tires. A tire should always be
rebalanced if it has been removed from
the wheel.

TIRE SIZE DESIGNATIONA tire’s sidewall is marked with a tire
size designation. You will need this
information when selecting replacement
tires for your car. The following explains
what the letters and numbers in the tire
size designation mean.
Example tire size designation :
P205/60R15 82T
P- Applicable vehicle type (tires marked
with the prefix “P” are intended for use
on passenger cars; however, not all tires
have this marking).
205- Tire width in millimeters.
60- Aspect Ratio. The tire’s section
height as a percentage of tire width.
R- Tire construction code (radial).
15- Rim diameter in inches.
82- Load Index: A numerical code
associated with the maximum load the
tire can carry.
T- Speed Rating symbol. See the speed
rating chart in this section for additional
information.
✻
NOTICE
• When replacing tires, never mix
radial, bias-belted, and bias-type
tires. All four tires should be of
the same size, design and
construction. Use only the tire
sizes listed on the Tire Label
attached to the passenger’s door.
Make sure that all tires and
wheels are the same size and
have the same load-carrying
capacity. Use only tire and wheel
combinations recommended on
the Tire Label or by an
Authorized Kia Dealer. Failure
to follow these precautions can
adversely affect the safety and
handling of your vehicle.
• The use of any other tire size or
type may seriously affect ride,
handling, ground clearance, tire
clearance, and speedometer
alibration.
• Driving on worn-out tires is very
hazardous and will reduce
braking effectiveness, steering
accuracy, and raction.
• It is best to replace all four tires
on your vehicle at the same time.
If that is not possible, then
replace the two front or two rear
tires as a pair.
Replacing just one tire can
seriously affect vehicle handling.

7-30WHEEL SIZE DESIGNATIONWheels are also marked with important
information that you need if you ever
need to replace one. The following
explains what the letters and numbers in
the wheel size designation mean.
Example wheel size designation: 15 X 6J
15 - Rim diameter in inches.
6 - Rim width in inches.
J - Rim contour designation.TIRE SPEED RATINGSThe following chart below shows many
of the different speed ratings currently
used for passenger car tires. The speed
rating symbol is part of the tire size
designation on the sidewall of the tire.
This symbol corresponds to that tire’s
designed maximum safe operating speed.
UNIFORM TIRE QUALITY
GRADINGThe following information relates to the
tire grading system developed by the
Canadian Motor Vehicle Safety Standard
(CMVSS) for grading tires by tread wear,
