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.

(%*

1. Be sure the vehicle is on levelground.
2. Start the engine and allow it to reach normal operating tempera‐
ture.
3. Turn the engine off and wait for a few minutes (about 5 minutes) for
the oil to return to the oil pan.
4. Pull the dipstick out, wipe it clean, and re-insert it fully.
WARNING
nRadiator hose
Be very careful not to touch the ra‐diator hose when checking or addingthe engine oil as it may be hotenough to burn you.
5. Pull the dipstick out again andcheck the level. The level should be
between F (Full) and L (Low).
CAUTION
•Do not overfill the engine oil. Itmay damage the engine
•Do not spill engine oil, when addingor changing engine oil. If you dropthe engine oil on the engine room,wipe it off immediately.
•When you wipe the oil level gauge,you should wipe it with a cleancloth. When mixed with debris, itcan cause engine damage.

If it is near or at L (Low), add enough oil
to bring the level to F (Full). Do notoverfill.Use a funnel to help prevent oil frombeing spilled on engine components.
Use only the specified engine oil. (Refer
to L

WARNING
Used engine oil may cause skin irri‐tation or cancer if left in contactwith the skin for prolonged periodsof time. Used engine oil containschemicals that have caused cancer inlaboratory animals. Always protectyour skin by washing your handsthoroughly with soap and warm wa‐ter as soon as possible after han‐dling used oil.

Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery. • If the battery becomes discharged in a short time (because, for example,the headlights or interior lights were
left on while the vehicle was not in
use), recharge it by slow charging
(trickle) for 10 hours.
• If the battery gradually discharges because of high electric load while
the vehicle is being used, recharge it
at 20-30A for two hours.
WARNING
nRecharging battery
When recharging the battery, ob‐serve the following precautions:•The battery must be removedfrom the vehicle and placed in anarea with good ventilation.
•Do not allow cigarettes, sparks, orflame near the battery.
•Watch the battery during charg‐ing, and stop or reduce the charg‐ing rate if the battery cells begingassing (boiling) violently or if thetemperature of the electrolyte ofany cell exceeds 49°C (120°F).
•Wear eye protection when check‐ing the battery during charging.
•Disconnect the battery charger inthe following order.1.Turn off the battery chargermain switch.
2.Unhook the negative clampfrom the negative battery ter‐minal.
3.Unhook the positive clamp fromthe positive battery terminal.
WARNING
•Before performing maintenance orrecharging the battery, turn off allaccessories and stop the engine.
•The negative battery cable mustbe removed first and installed lastwhen the battery is disconnected.
•Operation related to the battery isrecommended to an authorized Kiadealer.
CAUTION
•Keep the battery away from wa‐ter or any liquid.
•For your safety, we recommendthat you use parts for replace‐ment from an authorized Kia deal‐er.
Reset items
Items should be reset after the battery
has been discharged or the battery has been disconnected. • Auto up/down window (if equipped)
• Sunroof (if equipped)

❈Left side: Normal Right side: Blown
A vehicle’s electrical system is protec‐
ted from electrical overload damage by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver’s side panel
bolster, the others in the engine com‐ partment near the battery.
If any of your vehicle’s lights, accesso‐
ries, or controls do not work, check the
appropriate circuit fuse. If a fuse has blown, the element inside the fuse will
melt.
If the electrical system does not work,
first check the driver’s side fuse panel.
Before replacing a blown fuse, discon‐ nect the negative battery cable.
Always replace a blown fuse with one
of the same rating.
If the replacement fuse blows, this indi‐
cates an electrical problem. Avoid using the system involved and immediately
consult an authorized Kia dealer.
Three kinds of fuses are used: blade
type for lower amperage rating, car‐ tridge type, and multi fuse for higher
amperage ratings.
WARNING
nFuse replacement
•Never replace a fuse with anythingbut another fuse of the same rat‐ing.
•A higher capacity fuse could causedamage and possibly a fire.
•Never install a wire or aluminumfoil instead of the proper fuseeven as a temporary repair. It maycause extensive wiring damageand a possible fire.
•Do not arbitrarily modify or add-on electric wiring of the vehicle.
CAUTION
Do not use a screwdriver or any oth‐er metal object to remove fuses be‐cause it may cause a short circuitand damage the system.
