僅 As it is normal for engine oil to be consumed during driving, the engine oil
level should be checked on regular basis.
僅 The engine oil change interval for normal operating conditions is based on
the use of the recommended engine specification.
If the recommended engine oil specification is not used, then replace the
engine oil according to the maintenance schedule under severe operating
conditions.
僅 Never add any additives to the engine oil. Engine oil additives can change the
properties of engine oil and may cause serious engine failure.
僅 The engine oil level should be checked regularly and maintained properly.
Operating with an insufficient amount oil can damage the engine, and such
damage is not covered by warranty.
僅 This maintenance schedule depends on fuel quality. It is applicable only
when using a qualified fuel <"EN590 or equivalent">. If the diesel fuel specifi-
cations don't meet the EN590, it must be replaced according to the severe
maintenance schedule.
僅 Never add any additives to the engine oil. Engine oil additives can change the
properties of engine oil and may cause serious engine failure.
When adding coolant, use only deionized water or soft water for your vehicle
and never mix hard water in the coolant filled at the factory. An improper cool-
ant mixture can result in serious malfunction or engine damage.
僅 Adjust alternator, water pump and air conditioner drive belt. Inspect and if
necessary repair or replace.
僅 Inspect drive belt tensioner, idler and alternator pulley and if necessary cor-
rect or replace.
For your convenience, it can be replaced prior to it's interval when you do main-
tenance of other items.
Transfer case oil should be changed anytime it has been submerged in water.
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 more frequently. Kia recommend
"every 7,500 km (5,000 miles) inspection, every 15,000 km (10,000 miles)
replacement". If there are some important safety matters like fuel flow restric-
tion, surging, loss of power, hard starting problem etc, replace the fuel filter
immediately regardless of maintenance schedule and consult a professional
workshop. Kia recommends to consult an authorised Kia dealer/service partner.
