Owner maintenance precau-
tions
Improper or incomplete service may
result in problems. This section gives
instructions only for the maintenance
items that are easy to perform.
As explained earlier in this section,
several procedures can be done only
by an authorized Kia dealer with spe-
cial tools.
✽ ✽NOTICE
Improper owner maintenance dur-
ing the warranty period may affect
warranty coverage. For details, read
the separate Warranty & Consumer
Information manual provided with
the vehicle. If you're unsure about
any servicing or maintenance proce-
dure, have it done by an authorized
Kia dealer.
WARNING- Maintenance
work
Do not wear jewelry or loose
clothing while working under
the hood of your vehicle with
the engine running. These can
become entangled in moving
parts, if you must run the
engine while working under the
hood, make certain that you
remove all jewelry (especially
rings, bracelets, watches, and
necklaces) and all neckties,
scarves, and similar loose
clothing before getting near the
engine or cooling fans.

2. Tire size designation
A tire’s sidewall is marked with a tire
size designation. You will need this
information when selecting replace-
ment tires for your car. The following
explains what the letters and num-
bers in the tire size designation
mean.
Example tire size designation:
(These numbers are provided as an
example only; your tire size designa-
tor could vary depending on your
vehicle.)
P205/55R16 89H
P - Applicable vehicle type (tiresmarked with the prefix “P’’ are
intended for use on passenger
vehicles or light trucks; however,
not all tires have this marking).
205 - Tire width in millimeters.
55 - Aspect ratio. The tire’s section height as a percentage of its
width.
R - Tire construction code (Radial).
16 - Rim diameter in inches. 89 - Load Index, a numerical code
associated with the maximum
load the tire can carry.
H - Speed Rating Symbol. See the speed rating chart in this section
for additional information.
Wheel size designation
Wheels are also marked with impor-
tant information that you need if you
ever have to replace one. The follow-
ing explains what the letters and
numbers in the wheel size designa-
tion mean.
Example wheel size designation:
6.0JX16
6.0 - Rim width in inches.
J - Rim contour designation.
16 - Rim diameter in inches. Tire speed ratings
The chart below lists many of the dif-
ferent speed ratings currently being
used for passenger vehicles. 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.
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 240 km/h (Above 149 mph)

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 440
TRACTION A
TEMPERATURE A
Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate of
the 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.Tires degrade over time, even when
they are not being used. Regardless
of the remaining tread, we recom-
mend that tires be replaced after
approximately six (6) years of nor-
mal service. Heat caused by hot cli-
mates or frequent high loading con-
ditions can accelerate the aging
process.
These grades are molded on the
side-walls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicles
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 tires ability to
stop on wet pavement as measured
under controlled conditions on spec-
ified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perform-
ance.
The traction grade assigned to this
tire is based on straight-ahead brak-
ing traction tests, and does not
include acceleration, cornering,
hydroplaning, or peak traction char-
acteristics.

Maintenance
LIGHT BULBS
Use only the bulbs of the specifiedwattage.
If you don’t have necessary tools, the
correct bulbs and the expertise, con-
sult an authorized Kia dealer. In
many cases, it is difficult to replace
vehicle light bulbs because other
parts of the vehicle must be removed
before you can get to the bulb. This is
especially true if you have to remove
the headlight assembly to get to the
bulb(s). Removing/installing the
headlight assembly can result in
damage to the vehicle.Headlight, position light, turn
signal light, side marker light,
and front fog light bulb
replacementWARNING - Lights
Prior to working on the light,
firmly apply the parking brake,
ensure that the ignition switch
is turned to the “LOCK” position
and turn off the lights to avoid
burning your fingers or receiv-
ing an electric shock.
CAUTION - Light replacement
Be sure to replace the burned-out bulb with one of the samewattage rating. Otherwise, itmay cause damage to the fuseor electric wiring system.OTF074027N

Specifications & Consumer information
Recommended SAE viscosity
number
Always be sure to clean the area
around any filler plug, drain plug, or
dipstick before checking or draining
any lubricant. This is especially
important in dusty or sandy areas
and when the vehicle is used on
unpaved roads. Cleaning the plug
and dipstick areas will prevent dirt
and grit from entering the engine and
other mechanisms that could be
damaged.Engine oil viscosity (thickness) has
an effect on fuel economy and cold
weather operation (engine start and
engine oil flowability). Lower viscosi-
ty engine oils can provide better fuel
economy and cold weather perform-
ance, however, higher viscosity
engine oils are required for satisfac-
tory lubrication in hot weather.
Using oils of any viscosity other than
those recommended could result in
engine damage.
When choosing an oil, consider the
range of temperature your vehicle will
be operated in before the next oil
change. Proceed to select the recom-
mended oil viscosity from the chart.

*1. For better fuel economy, it is recommended to use the engine oil of
a viscosity grade SAE 5W-20 (API SM / ILSAC GF-4). However, if
the engine oil is not available in your country, select the proper
engine oil using the engine oil viscosity chart.
