Maintenance
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.
Cooling System
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Intelligent Variable
Transmission (IVT) Fluid
(if equipped)
Intelligent Variable Transmission
(IVT) Fluid should not be checked
under normal usage conditions. But,
the Intelligent Variable Transmission
(IVT) Fluid should be changed under
severe usage conditions. We recom-
mend that the Intelligent Variable
Transmission (IVT) Fluid changed by
an authorized HYUNDAI dealer
according to the maintenance sched-
ule.
(Refer to "Maintenance Under
Severe Usage Conditions" in this
chapter.)
Intelligent variable transmission
(IVT) fluid color is basically light
amber.
As the vehicle is driven, the intelli-
gent variable transmission (IVT)
fluid will begin to look darker. This
is a normal condition and you
should not judge the need to
replace the fluid based upon the
changed color.
NOTICE
The use of non-specified fluid
(even marked as compatible
with genuine) could result in
shift quality deterioration and
vibrations, eventually, the trans-
mission failure.
Use only specified Intelligent
Variable Transmission (IVT)
fluid. (Refer to "Recommended
lubricants and capacities" in
chapter 8.)

Maintenance
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 sole-
noid 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 evap-
orated 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.
3. Exhaust Emission Control
System
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
while maintaining good vehicle per-
formance.
When the engine starts or fails to
start, excessive attempts to restart
the engine may cause damage to the
emission system.
Engine exhaust (carbon monox-
ide) precautions
Carbon monoxide can be present
with other exhaust fumes. If you
smell exhaust fumes of any kind in
your vehicle, drive with all the win-
dows fully open. Have your vehicle
checked and repaired immediately.
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
on this page to avoid CO poi-
soning.
