Tire replacement
If the tire is worn evenly, a tread wear indicator will appear as a solid band
across the tread. This shows there isless than 1.6 mm (1/16 in.) of tread
left on the tire. Replace the tire when
this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tire.
OEN076053
Tread wear indicatorWARNING - Replacing
tires
To reduce the chance of serious
or fatal injuries from an acci-
dent caused by tire failure or
loss of vehicle control:
Replace tires that are worn, show uneven wear, or are
damaged. Worn tires can
cause loss of braking effec-
tiveness, steering control, andtraction.
Do not drive your vehicle with too little or too much pressure
in your tires. This can lead to
uneven wear and tire failure.
When replacing tires, never mix radial and bias-ply tires
on the same car. You must
replace all tires (including the
spare) if moving from radial to
bias-ply tires.
(Continued)(Continued)
Using tires and wheels otherthan the recommended sizes
could cause unusual handling
characteristics and poor vehi-
cle control, resulting in a seri-ous accident.
Wheels that do not meet KIA’s specifications may fit poorly
and result in damage to the
vehicle or unusual handling
and poor vehicle control.
The ABS works by comparing the speed of the wheels. The
tire size affects wheel speed.
When replacing tires, all 4
tires must use the same size
originally supplied with the
vehicle. Using tires of a differ-
ent size can cause the
ABS(Anti-lock Brake System)
and ESP(Electronic Stability
Program) to work irregularly.

Tire speed ratings
The chart below lists many of the dif-
ferent speed ratings currently being
used for passenger car tires. The
speed rating is part of the tire size
designation on the sidewall of the
tire. This symbol corresponds to that
tire's designed maximum safe oper-ating speed.3. Checking tire life (TIN : Tire
Identification Number)
Any tires that are over 6 years old,
based on the manufacturing date,(including the spare tire) should be
replaced by new ones. You can find
the manufacturing date on the tire
sidewall (possibly on the inside of the
wheel), displaying the DOT Code.
The DOT Code is a series of num-
bers on a tire consisting of numbers
and English letters. The manufactur-
ing date is designated by the last four
digits (characters) of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT means a
plant code number, tire size and
tread pattern and the last four num-
bers indicate week and year manu-
factured.
For example:
DOT XXXX XXXX 1609 represents
that the tire was produced in the 16th
week of 2009.
4. Tire ply composition and material
The number of layers or plies of rub-
ber-coated fabric in the tire. Tire
manufacturers also must indicate the
materials in the tire, which include
steel, nylon, polyester, and others.
The letter "R" means radial ply con-
struction; the letter "D" means diago-
nal or bias ply construction; and theletter "B" means belted-bias ply con-
struction.
S 180 km/h (112 mph)
T 190 km/h (118 mph)
H 210 km/h (130 mph) V 240 km/h (149 mph)
Z Above 240 km/h (149 mph)

WARNING - Tire age
Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, we recommend that tires
be replaced after approximately
six (6) years of normal service.
Heat caused by hot climates orfrequent high loading condi-
tions can accelerate the aging
process. Failure to follow this
warning can result in sudden
tire failure, which could lead to
a loss of control and an acci-
dent involving serious injury ordeath.

5. Maximum permissible inflationpressure
This number is the greatest amount of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tire and Loading Information
label for recommended inflation
pressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.
7. Uniform tire quality grading
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and maxi-
mum section width.
For example:
TREADWEAR 200
TRACTION AA
TEMPERATURE A
Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate ofthe tire when tested under controlled
conditions on a specified govern-
ment test course. For example, a tire
graded 150 would wear one-and-a-
half times (1½) as well on the gov-
ernment course as a tire graded 100.
The relative performance of tires depends upon the actual conditions
of their use, however, and may
depart significantly from the norm
due to variations in driving habits,
service practices and differences in
road characteristics and climate. These grades are molded on the
side-walls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicle
may vary with respect to grade.
Traction - AA, A, B & C
The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tire’s ability to
stop on wet pavement as measuredunder controlled conditions on spec-
ified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perform-
ance.
WARNING
The traction grade assigned to this tire is based on straight-ahead braking traction tests,
and does not include accelera-
tion, cornering, hydroplaning,
or peak traction characteristics.

LIGHT BULBS
Use only the bulbs of the specifiedwattage.
✽✽ NOTICE
After driving in heavy rain or washing,
headlight and taillight lenses could
appear frosty. This condition is caused by
the temperature difference between the
lamp inside and outside. This is similar
to the condensation on your windows
inside your vehicle during the rain and
doesn’t indicate a problem with your
vehicle. If the water leaks into the lamp
bulb circuitry, have the vehicle checked
by an authorized KIA dealer.

(4) Front fog light (if equipped)
WARNING - Working on
the lights
Prior to working on the light, firmly
apply the parking brake, ensure
that the ignition switch is turned tothe LOCK position and turn off the
lights to avoid sudden movement
of the vehicle and burning your fin-
gers or receiving an electric shock.
WARNING
Be sure to replace the burned-out
bulb with one of the same wattage
rating. Otherwise, it may cause
extensive wiring damage and pos-
sible fire.
CAUTION
If you don’t have necessary tools, the correct bulbs and the expertise,
consult an authorized KIA dealer. Inmany cases, it is difficult to replacevehicle light bulbs because other parts of the vehicle must be
removed before you can get to thebulb. This is especially true if youhave to remove the headlight
assembly to
get to the bulb(s).
Removing/installingthe headlight
assembly can result in damage to the vehicle.OXM079029

Exterior care
Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning andcaution statements that appear on thelabel.
Finish maintenance
Washing
To help protect your vehicle’s finish from
rust and deterioration, wash it thoroughlyand frequently at least once a month with
lukewarm or cold water.
If you use your vehicle for off-road driv-
ing, you should wash it after each off-
road trip. Pay special attention to the
removal of any accumulation of salt, dirt,
mud, and other foreign materials. Make
sure the drain holes in the lower edges of
the doors and rocker panels are keptclear and clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar deposits
can damage your vehicle’s finish if not
removed immediately.
Even prompt washing with plain water
may not completely remove all these
deposits. A mild soap, safe for use on
painted surfaces, may be used. After washing, rinse the vehicle thor-
oughly with lukewarm or cold water. Do
not allow soap to dry on the finish.
APPEARANCE CARE
WARNING -
Wet brakes
After washing the vehicle, test the
brakes while driving slowly to see if
they have been affected by water. If
braking performance is impaired,
dry the brakes by applying them
lightly while maintaining a slow for-
ward speed.
CAUTION
Water washing in the engine com- partment including high pressure
water washing may cause the fail-ure of electrical circuits located inthe engine compartment.
Never allow water or other liquids to come in contact with electri-cal/electronic components insidethe vehicle as this may damage them.
OJB037800
CAUTION
Do not use strong soap, chemical detergents or hot water, and donot wash the vehicle in direct
sunlight or when the body of thevehicle is warm.
Be careful when washing the side windows of your vehicle.
Especially, with high-pressurewater, water may leak through thewindows and wet the interior.
To prevent damage to the plastic parts, do not clean with chemicalsolvents or strong detergents.

EMISSION CONTROL SYSTEM (IF EQUIPPED)
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty infor-
mation contained in the Warr anty &
Maintenance book in y our vehicle.
Your vehicle is equipped with an emis-
sion control system to meet all applicable
emission regulations. There are three emission control sys-
tems, as follows.
(1) Crankcase emission control system
(2) Evaporative emission control system(3) Exhaust emission control system In order to assure the proper function of
the emission control systems, it is rec-
ommended that you have your vehicle
inspected and maintained by an author-
ized KIA dealer in accordance with the
maintenance schedule in this manual. Caution for the Inspection and
Maintenance Test (With Electronic
Stability Program (ESP) system)
To prevent the vehicle from misfir-
ing during dynamometer testing,
turn the Electronic Stability
Program (ESP) system off by press-
ing the ESP switch.
After dynamometer testing is com- pleted, turn the ESP system back on
by pressing the ESP switch again. 1. Crankcase emission control
system
The positive crankcase ventilation sys-
tem is employed to prevent air pollution
caused by blow-by gases being emitted
from the crankcase. This system supplies
fresh filtered air to the crankcase through
the air intake hose. Inside the crankcase,
the fresh air mixes with blow-by gases,
which then pass through the PCV valveinto the induction system.
2. Evaporative emission control
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.
