Finish damage repair
Deep scratches or stone chips in the
painted surface must be repaired
promptly. Exposed metal will quickly
rust and may develop into a major repair
expense.
NOTICE
If your vehicle is damaged and requires
any metal repair or replacement,
be sure the body shop applies anti-
corrosion materials to the parts
repaired or replaced.
NOTICE
Matte paint finish vehicle (if equipped)
In case of matte paint finish vehicles,
it is impossible to modify only the
damaged area and repair of the whole
part is necessary. If the vehicle is
damaged and painting is required,
we recommend that you have your
vehicle maintained and repaired by
an authorized HYUNDAI dealer. Take
extreme care, as it is difficult to restore
the quality after the repair.
Bright-metal maintenance
[To remove road tar and insects, use
a tar remover, not a scraper or other sharp object.

[ To protect the surfaces of brightmetal
parts from corrosion, apply a coating
of wax or chrome preservative and rub
to a high luster.

[ During winter weather or in coastal
areas, cover the bright metal parts
with a heavier coating of wax or
preservative. If necessary, coat the
parts with non-corrosive petroleum
jelly or other protective compound. Underbody maintenance
Corrosive materials used for ice and
snow removal and dust control may
collect on the underbody. If these
materials are not removed, accelerated
rusting can occur on underbody parts
such as the fuel lines, frame, floor pan
and exhaust system, even though they
have been treated with rust protection.
Thoroughly flush the vehicle underbody
and wheel openings with lukewarm or
cold water once a month, after off-road
driving and at the end of each winter. Pay
special attention to these areas because
it is difficult to see all the mud and dirt.
It will do more harm than good to wet
down the road grime without removing
it. The lower edges of doors, rocker
panels, and frame members have drain
holes that should not be allowed to clog
with dirt; trapped water in these areas
can cause rusting.
WARNING
After washing the vehicle, test the
brakes while driving slowly to see if
they have been affected by water. If
braking performance is impaired, dry
the brakes by applying them lightly
while maintaining a slow forward speed.
Aluminum wheel maintenance
The aluminum wheels are coated with a
clear protective finish.

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

3. Exhaust Emission Control System
The Exhaust Emission Control System is
a highly effective system which controls
exhaust emissions while maintaining
good vehicle performance.
When the engine starts or fails to start,
excessive attempts to restart the engine
may cause damage to the emission
system.
Engine exhaust (carbon monoxide)
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 windows
fully open. Have your vehicle checked
and repaired immediately.
WARNING
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 poisoning.
[ Do not operate the engine in confined
or closed areas (such as garages) any
more than what is necessary to move
the vehicle in or out of the area.

[ When the vehicle is stopped in an
open area for more than a short time
with the engine running, adjust the
ventilation system (as needed) to draw
outside air into the vehicle.

[ Never sit in a parked or stopped
vehicle for any extended time with the engine running.

[ When the engine stalls or fails to
start, excessive attempts to restart
the engine may cause damage to the
emission control system. Operating precautions for catalytic
converters (if equipped)
WARNING
The exhaust system and catalytic
converter are very hot during and
immediately after the engine has been
running. To avoid SERIOUS INJURY or
DEATH:
[ Do not park, idle, or drive the vehicle
over or near flammable objects, such
as grass, vegetation, paper, leaves,
etc. A hot exhaust system can ignite
flammable items under your vehicle.

[ Keep away from the exhaust system
and catalytic converter or you may
get burned.
Also, Do not remove the heat sink
around the exhaust system, do not
seal the bottom of the vehicle, and
do not coat the vehicle for corrosion
control. It may present a fire risk under certain conditions.
Your vehicle is equipped with a catalytic
converter emission control device.
To prevent damage to the catalytic
converter and to your vehicle, take the
following precautions:
[ Use only UNLEADED FUEL for gasoline engines.

[ Do not operate the vehicle when
there are signs of engine malfunction,
such as misfire or a noticeable loss of
performance.

[ Do not misuse or abuse the engine.
Examples of misuse are coasting with
the hybrid system off and descending
steep grades in gear with the hybrid
system off.

[ Do not operate the engine at high
idle speed for extended periods (5
minutes or more).

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.
