The following maintenance services must be performed to ensure good emission control and performance. Keep receipts for all
vehicle emission services to protect your warranty. Where both mileage and time are shown, the frequency of service is deter-
mined by whichever occurs first.
*

: Check the engine oil level and leak every 500 km (350
miles) or before starting a long trip.
*
2
: This maintenance schedule depends on fuel quality. It is
applicable only when using a qualified fuel <"EN590 or
equivalent">. If the diesel fuel specifications don't meet the
EN590, it must be replaced according to the severe mainte-
nance schedule.

: If the recommended oil is not available, replace engine oil
and engine oil filter every 20,000 km or 12 months.

tained properly. Operating with an insufficient amount oil
can damage the engine, and such damage is not covered
by warranty.

: This maintenance schedule depends on fuel quality. It is
applicable only when using a qualified fuel <"EN590 or

EN590, it must be replaced more frequently. If there are
some important matters like fuel flow restriction, surging,
loss of power, hard starting problem etc, replace the fuel fil-
ter immediately regardless of maintenance schedule and
we recommend that you consult an authorised Kia dealer for
details.

coolant filled at the factory. An improper coolant mixture can
result in serious malfunction or engine damage.
