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 vehicle is
being driven in severe conditions, more
frequent oil and filter changes are
required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil satu-
ration and replace if necessary. Drive
belts should be checked periodically for
proper tension and adjusted as neces-
sary.
CAUTION
When you are inspecting the belt, place
the ignition switch in the LOCK/OFF or
ACC position.
Fuel filter cartridge (for diesel
engine)
A clogged filter can limit the speed at
which the vehicle may be driven, dam-
age the emission system and cause mul-
tiple issues such as hard starting. If an
excessive amount of foreign matter
accumulates in the fuel tank, the filter
may require replacement more fre-
quently.
After installing a new filter, run the
engine for several minutes, and check
for leaks at the connections. Have the
fuel filter replaced by a professional
workshop. Kia recommends to visit an
authorised Kia dealer/service partner.
Vapour hose and fuel filler cap
(for petrol engine)

Explanation of scheduled maintenance items

Fuel filter (for petrol engine)
Kia petrol vehicles are equipped a life-
time fuel filter that integrated with the
fuel tank. Regular maintenance or
replacement is not needed but depends
on fuel quality. If there are some import-
ant safety matters like fuel flow restric-
tion, surging, loss of power, hard starting
problem etc, fuel filter inspection or
replace is needed.
Have the fuel filter inspected or replaced
by a professional workshop. Kia recom-
mends to visit an authorised Kia dealer/
service partner.
Fuel lines, fuel hoses and connec-
tions
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. Have
the fuel lines, fuel hoses and connec-
tions replaced by a professional work-
shop. Kia recommends to visit an
authorised Kia dealer/service partner.
WARNING
Diesel only
Never work on the injection system with
the engine running or within 30 seconds
after shutting off the engine. High pres-
sure pump, rail, injectors and high pres-
sure pipes are subject to high pressure
even after the engine stops. The fuel jet
produced by fuel leaks may cause seri-
ous injury, if it touches the body. People
wearing a cardiac pacemaker should
maintain a distance of at least 30 cm
from the ECU or wiring harness within
the engine room whilst the engine is run-
ning, since the high currents in the Com-
mon Rail system produce considerable
magnetic fields.
The vapour hose and fuel filler cap
should be inspected at those intervals
