Maintenance
Wrinkles or abrasions which appear naturally from usage are
not covered by warranty.
Belts with metallic accessories, zippers or keys inside the back
pocket may damage the seat
fabric.
Make sure not to wet the seat. It may change the nature of natu-
ral leather.
Jeans or clothes which could bleach may contaminate the sur-
face of the seat covering fabric. Caring for the leather seats
- Vacuum the seat periodically toremove dust and sand on the
seat. It will prevent abrasion or
damage of the leather and main-
tain its quality.
- Wipe the natural leather seat cover often with dry or soft cloth.
- Use of a proper leather protector may prevent abrasion of the
cover and helps maintain the
colour. Be sure to read the
instructions and consult a spe-
cialist when using leather coating
or protective agents.
- Light coloured (beige, cream beige) leather is easily contami-
nated and the stain is noticeable.
Clean the seats frequently.
- Avoid wiping with wet cloth. It may cause the surface to crack. Cleaning the leather seats
- Remove all contaminationsinstantly. Refer to instructions
below for removal of each con-
taminant.
- Cosmetic products (sunscreen, foundation, etc.)
Apply cleansing cream on a cloth
and wipe the contaminated spot.
Wipe off the cream with a wet
cloth and remove water with a dry
cloth.
- Beverages(coffee, soft drink, etc.) Apply a small amount of neutral
detergent and wipe until contami-
nations do not smear.
- Oil Remove oil instantly with
absorbable cloth and wipe with
stain remover used only for natu-
ral leather.
- Chewing gum Harden the gum with ice and
remove gradually.

Cleaning the seat belt webbing
Clean the belt webbing with any mild
soap solution recommended for
cleaning upholstery or carpet. Follow
the instructions provided with the
soap. Do not bleach or re-dye the
webbing because this may weaken
the seat belt.
Cleaning the interior windowglass
If the interior glass surfaces of the
vehicle become fogged (that is, cov-
ered with an oily, greasy or waxy
film), they should be cleaned with
glass cleaner. Follow the directions
on the glass cleaner container.
Do not scrape or scratch the
inside of the rear window. This
may result in damage to the rear
window defroster grid. The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the
Warranty Booklet 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 sys-
tem
(2) Evaporative emission control sys- tem
(3) Exhaust emission control system
In order to ensure the proper func-
tion of the emission control systems,
it is recommended that you have
your vehicle inspected and main-
tained by a HYUNDAI authorised
repairer in accordance with the main-
tenance schedule. For the Inspection and Maintenance
Test (with Electronic Stability
Control (ESC) system)
To prevent the vehicle from mis-
firing during dynamometer test-
ing, 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.

Maintenance
1. Crankcase emission controlsystem
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 controlsystem
The Evaporative Emission Control
System is designed to prevent fuel
vapours from escaping into the
atmosphere.
Canister
Fuel vapours generated inside the
fuel tank are absorbed and stored in
the onboard canister. When the
engine is running, the fuel vapours
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 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
whilst 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 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 win-
dows fully open. Have your vehicle
checked and repaired immediately.
Engine exhaust gases contain
carbon monoxide (CO). Though
colourless and odourless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
on this page to avoid CO poi-
soning.
WARNING

Maintenance
Do not operate the engine in con-fined 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 cat-alytic converters (if equipped)Your vehicle is equipped with a cat-
alytic converter emission control
device.
To prevent damage to the catalytic
converter and to your vehicle, take
the following precautions:
Use only UNLEADED FUEL for
petrol engines.
Do not operate the vehicle when there are signs of engine malfunc-
tion, 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).
The exhaust system and cat-
alytic 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 flamma-
ble 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 convert-
er or you may get burned.
Also, Do not remove the heat
sink around the exhaust sys-
tem, do not seal the bottom of
the vehicle, and do not coat
the vehicle for corrosion con-
trol. It may present a fire risk
under certain conditions.
WARNING

Do not modify or tamper with anypart of the engine or emission con-
trol system. All inspections and
adjustments must be made by a
HYUNDAI authorised repairer.
Avoid driving with an extremely low fuel level.
Running out of fuel could cause
the engine to misfire, damaging
the catalytic converter.
Gasoline (Petrol) ParticulateFilter (GPF) (if equipped)
The Gasoline (Petrol) Particulate
Filter (GPF) system removes the
soot in the exhaust gas.
The GPF system automatically burns
(or oxidises) 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 nor-
mal/ high driving speeds. However, when the vehicle is contin-
ually driven at repeated short dis-
tances or driven at low speed for a
long time, the accumulated soot may
not be automatically removed
because of low exhaust gas temper-
ature. In this case, the accumulated
soot is out of the detection range, the
soot oxidization process does not
occur, and the Gasoline (Petrol)
Particulate Filter (GPF) Lamp ( )
Illuminates.
The Gasoline (Petrol) Particulate
Filter (GPF) Lamp stops illuminating,
when the driving speed exceeds 50
mph (80km/h) with engine rpm 1,500
~ 4,000 and the gear in the 3rd posi-
tion or above for approximately 30
minutes.
When the GPF Lamp continuously
blinks or the warning message
“Check exhaust system” illuminates in
the above cases, we recommend that
you have the GPF system checked by
a HYUNDAI authorised repairer.
When the vehicle is continuously
driven with the GPF Lamp flashing
for an extended period of time, it may
damage the GPF system and lower
the fuel economy.
Lean NOx Trap (if equipped)
The Lean NOx Trap (LNT) system
removes the nitrogen oxide from the
exhaust gas. A smell can occur in the
exhaust gas depending on the quali-
ty of the fuel, and it can degrade NOx
reduction performance. Please use
the regulated automotive diesel fuel.
Maintenance

Gasoline (Petrol) Fuel
(if equipped with GPF)
We recommend you to use only
the regulated petrol fuels, when
your vehicle is equipped with
the GPF system.
When you use other petrol fuels
which contain unspecified addi-
tives, they may damage the GPF
system and cause exhaust
emission problems.
