Maintenance
Cleaning the lap/shoulder beltwebbing
Clean the belt webbing with any mild
soap solution recommended for clean-
ing upholstery or carpet. Follow the
instructions provided with the soap. Do
not bleach or re-dye the webbing
because this may weaken it.
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 function
of the emission control systems, it is
recommended that you have your
vehicle inspected and maintained by
a HYUNDAI authorised repairer in
accordance with the maintenance
schedule.

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 con-trol system
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 con-
trols exhaust emissions whilst main-
taining good vehicle performance.

Maintenance
Engine exhaust gas precautions (carbon monoxide)
Carbon monoxide can be present
with other exhaust fumes. Therefore,
if you smell exhaust fumes of any
kind inside your vehicle, have it
inspected and repaired immediately.
If you ever suspect exhaust fumes
are coming into your vehicle, drive it
only with all the windows fully open.
Have your vehicle checked and
repaired immediately. 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)
Engine exhaust gases contain
carbon monoxide (CO). Though
colourless and odourless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
following to avoid CO poisoning.
WARNING
A hot exhaust system can
ignite flammable items under
your vehicle. Do not park, idle,
or drive the vehicle over or
near flammable objects, such
as dry grass, paper, leaves, etc.
The exhaust system and cat-
alytic system are very hot
whilst the engine is running or
immediately after the engine
is turned off. Keep away from
the exhaust system and cat-
alytic converter as 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 control. It
may present a fire risk under
certain conditions.

Maintenance
Your vehicle is equipped with a cat-
alytic converter emission control
device.
Therefore, the following precautions
must be observed:
Use only UNLEADED FUEL forpetrol 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 engine off and
descending steep grades in gear
with the engine off.
Do not operate the engine at high idle speed for extended periods (5
minutes or more). Do not modify or tamper with any
part of the engine or emission con-
trol system. All inspections and
adjustments must be made by a
HYUNDAI authorised repairer.
Avoid driving with a very low fuel level. If you run out of petrol, it
could cause the engine to misfire
and result in excessive loading of
the catalytic converter.
Failure to observe these precautions
could result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void
your warranties.Gasoline (Petrol) Particulate Filter (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 normal/
high driving speeds.
However, when the vehicle is continu-
ally 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 is out of the
detection range, the soot oxidization
process does not occur, and the
Gasoline (Petrol) Par ticulate Filter
(GPF) Lamp ( ) Illuminates.
Page 501 of 526

The Gasoline Particulate Filter
(GPF) Lamp stops illuminating, when
the driving speed exceeds 50 mph
(80 km/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.Diesel particulate filter (DPF) (if equipped)
The Diesel Particulate Filter (DPF)
system removes the soot in the
exhaust gas.
The DPF 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 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 Diesel Particulate
Filter (DPF) Lamp ( )
Illuminates.

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.
CAUTION
Page 502 of 526

The Diesel Particulate Filter (DPF)
Lamp stops illuminating, when the
driving speed exceeds 37mph (60
km/h), or when the engine rpm is
between 1,500 and 2,500 with the
gear in the 2nd position or above for
approximately 25 minutes.
When the DPF Lamp continuously
blinks or the warning message
“Check exhaust system” illuminates
in the above cases, we recommend
that you have the DPF system
checked by a HYUNDAI authorised
repairer.
When the vehicle is continuously
driven with the DPF Lamp flashing
for an extended period of time, it may
damage the DPF 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
Diesel Fuel
(if equipped with DPF)
We recommend you to use only
the regulated diesel fuels, when
your vehicle is equipped with
the DPF system.
When you use other diesel
fuels, which are high in sulfurs
(above 50 ppm) or that contain
unspecified additives, they may
damage the DPF system and
cause white smoke emissions.
CAUTION

Selective Catalytic Reduction
(if equipped)
The Selective Catalytic Reduction
(SCR) system is to catalytically con-
vert NOx to Nitrogen and Water by
using the reduction agent, the urea
solution.
Urea gauge (if equipped)
The urea solution gauge indicates
the approximate amount of remain-
ing urea solution inside the urea
solution tank.

The lack warning messages of Urea
appear below Urea 5.4 liter. When
the warning message "Low Urea" is
displayed with SCR warning lamp
( ), the urea tank needs to be
refilled. If not refilled for a consider-
able mileage, visual warning system
will escalate the intensity by display-
ing the message "Refill Urea" with
SCR warning lamp ( ).
In this case, the tank soon needs to
be refilled. The remaining urea in the
tank approaches to too low level the
warning message "Refill Urea tank
or vehicle will not start" with SCR
warning lamp ( ). "xxx km(mile)"
represents the remaining travel dis-
tance allowed, so do not continue
driving to the limit of the remaining
travel distance without refilling.Otherwise, the vehicle can't be
restarted once the engine is turned
off by ignition key. Based on the driv-
ing pattern, environmental condition
and road profile, the deducted
remaining mileage may differ from
the actual travel distance.
When "Low Urea" or "Refill Urea"
message is displayed, add enough
urea. When "Refill Urea tank or vehi-
cle will not start" message is dis-
played, fill up enough urea. When
"Refill Urea tank or vehicle will not
start" message is displayed with
SCR warning lamp ( ), the vehicle
can't be restarted once the engine is
turned off by ignition key. For the
above cases, full replenishment is
always recommended.
