Maintenance

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.

TIRES AND WHEELS

Tire care
For proper maintenance, safety, and
maximum fuel economy, you must al‐
ways maintain recommended tire infla‐ tion pressures and stay within the load
limits and weight distribution recom‐
mended for your vehicle.
Recommended cold tire inflation
pressures
All tire pressures (including the spare)
should be checked when the tires are cold. L
