Maintenance
9-12
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.
HSG (Hybrid Starter & Generator) Belt
The HSG belt should be changed at the
intervals specified in the maintenance schedule.
Fuel Lines, Fuel Hoses and Connections
Check the fuel lines, fuel hoses and
connections for leakage and damage.
We recommend an authorized HYUNDAI
dealer replace any damaged or leaking
parts immediately.
Fuel Filter
A clogged filter can limit the speed
at which the vehicle may be driven,
damage the emission system and cause
multiple issues such as hard starting. If
an excessive amount of foreign matter
accumulates in the fuel tank, the
filter may require replacement more
frequently. After installing a new filter,
run the engine for several minutes,
and check for leaks at the connections.
Fuel filters should be installed by an
authorized HYUNDAI dealer.
Vapor Hose and Fuel Filler Cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
a new vapor hose or fuel filler cap is
correctly replaced.
Air Cleaner Filter
A genuine HYUNDAI air cleaner filter
is recommended when the filter is
replaced.
Spark Plugs
Make sure to install new spark plugs of
the correct heat range.
When assembling parts, be sure to
wipe the inside and outside of the boot
bottom of the ignition coil and the
insulator of the spark plug with a soft
cloth to prevent contamination of the
spark plug insulator.
Cooling System
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Engine Coolant/Inverter Coolant
The coolant should be changed at the
intervals specified in the maintenance schedule.
Automatic Transmission Fluid
Automatic transmission fluid should
not be checked under normal usage conditions.
We recommend that the automatic
transmission fluid is changed by an
authorized HYUNDAI dealer according to
the maintenance schedule.
Engine Clutch Actuator Fluid
The engine clutch actuator fluid level
should be inspected or replaced to the
intervals specified in the maintenance schedule.
EXPLANATION OF SCHEDULED MAINTENANCE ITEMS

Maintenance
9-74
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Service
Passport in your vehicle.
Your vehicle is equipped with an
emission control system to meet all
applicable emission regulations. There
are three emission control systems, as
follows.
(1) Crankcase emission control system
(2) Evaporative emission control system
(3) Exhaust emission control system
In order to ensure the proper function
of the emission control systems, it
is recommended that you have your
vehicle inspected and maintained
by an authorized HYUNDAI dealer in
accordance with the maintenance schedule in this manual.
NOTICE
For the Inspection and Maintenance
Test (with Electronic Stability Control
(ESC) system)
[To prevent the vehicle from misfiring
during dynamometer testing, turn
the Electronic Stability Control
(ESC) system off by pressing the ESC
switch (ESC OFF light illuminated).

[ After dynamometer testing is
completed, turn the ESC system back
on by pressing the ESC switch again.
1. Crankcase Emission Control
System
The positive crankcase ventilation system
is employed to prevent air pollution
caused by blow-by gases being emitted
from the crankcase. This system supplies
fresh filtered air to the crankcase through
the air intake hose. Inside the crankcase,
the fresh air mixes with blow-by gases,
which then pass through the PCV valve
into the induction system.
2. Evaporative Emission Control System
The Evaporative Emission Control System
is designed to prevent fuel vapors from
escaping into the atmosphere.
Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in the
canister are drawn into the surge tank
through the purge control solenoid valve.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve
is controlled by the Engine Control
Module (ECM); when the engine coolant
temperature is low during idling, the
PCSV closes so that evaporated fuel
is not taken into the engine. After the
engine warms-up during ordinary
driving, the PCSV opens to introduce
evaporated fuel to the engine.
EMISSION CONTROL SYSTEM

Maintenance
9-76

[
Do not modify or tamper with any
part of the engine or emission control
system. We recommend that all
inspections and adjustments are
made by an authorized HYUNDAI
dealer.

[ Avoid driving with an extremely low
fuel level.
Running out of fuel could cause the
engine to misfire, damaging the
catalytic converter.
Gasoline Particulate Filter (GPF) (if equipped)
The Gasoline Particulate Filter (GPF)
system removes the soot in the exhaust gas.
The GPF system automatically burns
(or oxidizes) the accumulated soot in
accordance with driving situations,
unlike a disposable air filter.
In other words, the accumulated soot is
automatically purged out by the engine
control system and by the high exhaust-
gas temperature at normal/high driving speeds.
However, when the vehicle is continually
driven at repeated short distances or
driven at low speed for a long time,
the accumulated soot may not be
automatically removed because of low
exhaust gas temperature. In this case,
the accumulated soot may reach a
certain amount regardless of the soot
oxidization process, then the GPF lamp (
) will illuminate.
The Gasoline Particulate Filter (GPF)
Lamp stops illuminating, when the
driving speed exceeds 80 km/h (50 mph)
with engine rpm 1,500 ~ 4,000 and the
gear in the 3rd position or above for
approximately 30 minutes. When the GPF lamp starts to blink or
the warning message “Check exhaust
system” pops up even though the
vehicle was driven as mentioned above,
we recommend that you have the
GPF system checked by an authorized
HYUNDAI dealer.
With GPF lamp blinking for an extended
period of time, it may damage the GPF
system and lower the fuel economy.
CAUTION
We recommend you to use only the
regulated gasoline fuels, when your
vehicle is equipped with the GPF
system.
When you use other gasoline fuels
which contain unspecified additives,
they may damage the GPF system and
cause exhaust emission problems.
