maintenance KIA OPTIMA PLUG-IN HYBRID 2017 User Guide

Please note that the TPMS is not a
substitute for proper tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped
with a TPMS malfunction indicator to indicate when the system is not oper‐
ating properly. The TPMS malfunction
indicator is combined with the low tire pressure telltale. When the system de‐
tects a malfunction, the telltale will
flash for approximately 1 minute and then remain continuously illuminated.
This sequence will continue upon sub‐
sequent vehicle start-ups as long as the malfunction exists. When the TPMS
malfunction indicator remains illumina‐
ted after blinking for approximately 1 minute, the system may not be able to
detect or signal low tire pressure as in‐
tended. TPMS malfunctions may occur for a va‐
riety of reasons, including the installa‐
tion of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more tires or wheels on your vehicle to en‐
sure that the replacement or alternate
tires and wheels allow the TPMS to continue to function properly.
NOTICE
If any of the below happens, we rec‐
ommend that the system be
checked by an authorized Kia dealer.
1.The low tire pressure telltale/
TPMS malfunction indicator do
not illuminate for 3 seconds
when the ignition switch is
turned to the ON position or en‐
gine is running.
2.The TPMS malfunction indicator
remains illuminated after blink‐
ing for approximately 1 minute.
3.The Low tire pressure position
telltale remains illuminated.

NORMAL MAINTENANCE SCHEDULE - FOR GASOLINE ENGINE [FOR EUROPE (EXCEPT RUSSIA)]
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 determined by whichever occurs first.
NO.ITEMREMARK
*1 Coolant (Engine / Inverter) 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
coolant mixture can result in serious malfunction or engine damage.
*2 Engine oil and engine oil filter Check the engine oil level and leak every 500 km (350 miles) or before start‐ing a long trip.
*3 Fuel additives (Gasoline) Kia recommends that you use unleaded gasoline which has an octane rating
of RON (Research Octane Number) 95 / AKI (Antiknock Index) 91 or higher
(for Europe) or Octane Rating of RON (Research Octane Number) 91 / AKI(Antiknock Index) 87 or higher (except Europe).
For customers who do not use good quality gasolines including fuel additives
regularly, and have problems starting or the engine does not run smoothly,
one bottle of additives added to the fuel tank at every 15,000 km (for Eu‐rope, Australia and New Zealand)/10,000 km (except Europe, Australia andNew Zealand).
Additives are available from your authorized Kia dealer along with informa‐
tion on how to use them. Do not mix other additives.
*4 HSG (Hybrid Starter & Generator) belt Inspect HSG belt for evidence of cuts, crocks, excessive wear or oil saturation
and replace if necessary. If drive belt noise occurred, readjust drive belt ten‐
sion before replace.
*5 Spark plug For your convenience, it can be replaced prior to it's interval when you domaintenance of other items.
