EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in the maintenance schedule. If the vehi‐
cle is being driven in severe conditions,
more frequent oil and filter changes are required.
HSG (hybrid starter &
generator) belt
The HSG belt should be changed at the
intervals specified in the maintenance schedule.
Fuel filter (for gasoline)
Kia gasoline vehicle is equipped a life‐
time fuel filter that integrated with the fuel tank. Regular maintenance or re‐
placement is not needed but depends
on fuel quality. If there are some im‐ portant safety matters like fuel flow
restriction, surging, loss of power, hard
starting problem etc, fuel filter inspec‐ tion or replace is needed.
We recommend that the fuel filter be
Inspected or replaced by an authorized
Kia dealer.
Fuel lines, fuel hoses and
connections
Check the fuel lines, fuel hoses and
connections for leakage and damage. We recommend that the fuel lines, fuel
hoses and connections be replaced by
an authorized Kia dealer.
Vapor hose (for gasoline engine)
and fuel filler cap
The vapor hose and fuel filler cap
should be inspected at those intervals
specified in the maintenance schedule.
Make sure that a new vapor hose or
fuel filler cap is correctly replaced.
Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evi‐
dence of heat and/or mechanical dam‐ age. Hard and brittle rubber, cracking,
tears, cuts, abrasions, and excessive
swelling indicate deterioration. Particu‐ lar attention should be paid to examine
those hose surfaces nearest to high
heat sources, such as the exhaust manifold. Inspect the hose routing to assure that
the hoses do not come in contact with
any heat source, sharp edges or mov‐ ing component which might cause heat
damage or mechanical wear. Inspect all
hose connections, such as clamps and couplings, to make sure they are se‐
cure, and that no leaks are present. Ho‐
ses should be replaced immediately if there is any evidence of deterioration
or damage.
Air cleaner filter
We recommend that the air cleaner fil‐
ter be replaced by an authorized Kia dealer.
Spark plugs (for gasoline engine)
Make sure to install new spark plugs of
the correct heat range.
WARNING
Do not disconnect and inspect sparkplugs when the engine is hot. Youmay burn yourself.

this section for additional
information.
Wheel size designation
Wheels are also marked with important
information that you need if you ever have to replace one. The following ex‐
plains what the letters and numbers in
the wheel size designation mean. Example wheel size designation:
7.5JX19
7.5 - Rim width in inches.
J - Rim contour designation.
19 - Rim diameter in inches.
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 designa‐ tion on the sidewall of the tire. This
symbol corresponds to that tire's de‐
signed maximum safe operating speed.
SpeedRatingSymbolMaximum 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)
SpeedRatingSymbolMaximum Speed
Z Above 240 km/h (149
mph)
3. Checking tire life (TIN: Tire
Identification Number)
Any tires that are over 6 years old,
based on the manufacturing date, (in‐ cluding the spare tire) should be re‐
placed 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 numbers on a tire consist‐ ing of numbers and English letters. The
manufacturing 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 numbers indi‐ cate week and year manufactured.
For example:
DOT XXXX XXXX 1616 represents that
the tire was produced in the 16th week
of 2016.
WARNING
nTire age
Tires degrade over time, even whenthey are not being used.Regardless of the remaining tread,we recommend that tires be re‐placed after approximately six (6)years of normal service. Heat causedby hot climates or frequent highloading conditions can accelerate theaging process. Failure to follow thiswarning can result in sudden tirefailure, which could lead to a loss ofcontrol and an accident involving se‐rious injury or death.
4. Tire ply composition and material
The number of layers or plies of rub‐
ber-coated fabric in the tire. Tire man‐ ufacturers also must indicate the ma‐
terials in the tire, which include steel,
nylon, polyester, and others. The letter "R" means radial ply construction; the
letter "D" means diagonal or bias ply
construction; and the letter "B" means belted-bias ply construction.

Maintenance

Don't neglect the interior
Moisture can collect under the floor
mats and carpeting and cause corro‐
sion. Check under the mats periodically to be sure the carpeting is dry. Use
particular care if you carry fertilizers,
cleaning materials or chemicals in the vehicle.
These should be carried only in proper
containers and any spills or leaks
should be cleaned up, flushed with clean water and thoroughly dried.
Interior care
Interior general precautions
Prevent chemicals such as perfume,
cosmetic oil, sun cream, hand cleaner, and air freshener from contacting the
interior parts because they may cause
damage or discoloration. If they do con‐ tact the interior parts, wipe them off
immediately. If necessary, use a vinyle
cleaner, see instructions for correct us‐ age.
CAUTION
Never allow water or other liquids tocome in contact with electrical/elec‐
(Continued)
(Continued)
tronic components inside the vehicleas this may damage them.
CAUTION
When cleaning leather products(steering wheel, seats etc.), useneutral detergents or low alcoholcontent solutions. If you use high al‐cohol content solutions or acid/alka‐line detergents, the color of theleather may fade or the surface mayget stripped off.
Cleaning the upholstery and
interior trim
Vinyl
Remove dust and loose dirt from vinyl
with a whisk broom or vacuum cleaner. Clean vinyl surfaces with a vinyl clean‐
er.
Fabric
Remove dust and loose dirt from fabric
with a whisk broom or vacuum cleaner. Clean with a mild soap solution recom‐
mended for upholstery or carpets. Re‐
move fresh spots immediately with a fabric spot cleaner. If fresh spots do
not receive immediate attention, fabric
can be stained and its color can be af‐ fected. Also, its fire-resistant proper‐
ties can be reduced if the material is
not properly maintained.
CAUTION
Using anything but recommendedcleaners and procedures may affectthe fabric’s appearance and fire-re‐sistant properties.
Cleaning the lap/shoulder belt
webbing
Clean the belt webbing with any mild
soap solution recommended for clean‐ ing upholstery or carpet. Follow the in‐
structions provided with the soap. Do
not bleach or re-dye the webbing be‐ cause this may weaken it.
