Maintenance
High-pressure washing
• When using high-pressure washers,make sure to maintain sufficient dis-
tance from the vehicle.
Insufficient clearance or excessive
pressure can lead to component
damage or water penetration.
• Do not spray the camera, sensors or its surrounding area directly with a
high pressure washer. Shock
applied from high pressure water
may cause the device to not operate
normally.
• Do not bring the nozzle tip close to boots (rubber or plastic covers) or
connectors as they may be dam-
aged if they come into contact with
high pressure water. • Water washing in the engine com-
partment including high pressure
water washing may cause the fail-
ure of electrical circuits located in
the engine compartment.
• Never allow water or other liquids to come in contact with electri-
cal/electronic components inside
the vehicle as this may damage
them.
Waxing
Wax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle
before waxing. Use a good quality
liquid or paste wax, and follow the
manufacturer’s instructions. Wax all
metal trim to protect it and to main-
tain its luster. Removing oil, tar, and
similar materials with a spot remover
will usually strip the wax from the fin-
ish. Be sure to re-wax these areas
even if the rest of the vehicle does
not yet need waxing.
• Wiping dust or dirt off the bodywith a dry cloth will scratch the
finish.
• Do not use steel wool, abrasive cleaners, or strong detergents
containing highly alkaline or
caustic agents on chrome-plated
or anodized aluminium parts.
This may result in damage to the
protective coating and cause dis-
colouration or paint deteriora-
tion.

Maintenance
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.
Vehicle modifications
This vehicle should not be modified.
Modification of your vehicle could
affect its performance, safety or
durability and may even violate gov-
ernmental safety and emissions reg-
ulations.
In addition, damage or performance
problems resulting from any modifi-
cation may not be covered under
warranty.
• If you use unauthorised electronic
devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorised
electronic devices.
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.

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)
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, you may get burned.
Also, do not remove the heat
sink around the exhaust sys-
tem, do not seal the bottom of
the vehicle or 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:Failure to observe these precautions
could result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void
your warranties.
• Use only UNLEADED FUEL
for petrol engine.
• 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 engine
off and descending steep
grades in gear with the engine
off.
(Continued)(Continued)
•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 control 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 cat-
alytic converter.

Diesel particulate filter (DPF) (if equipped)
The Diesel Particulate Filter (DPF)
system removes the soot in the
exhaust gas. Unlike a disposable air
filter, the DPF system automatically
burns (oxidizes) and removes the
accumulated soot according to the
driving condition. In order words, the
active burning by engine control sys-
tem and high exhaust gas tempera-
ture caused by normal/high diving
condition burns and removes the
accumulated soot.
However, if the vehicle continues to
be driven at repeated short distance
or driven at low speed for a long
time, the accumulated soot may not
be automatically removed because
of low exhaust gas temperature.
More than a certain amount of soot
deposited, the malfunction indicator
light ( ) illuminates.
When the malfunction indicator light
illuminates, it may turn-off after driv-
ing the vehicle at more than 60km/h
(37 mph) or at more than second
gear with 1500~2500 engine rpm for
a certain time (for about 25 minutes). If the malfunction indicator light
( ) continues to be blinked or the
warning massage “Check exhaust
system” illuminates in spite of the
procedure, visit a professional work-
shop and check the DPF system.
HYUNDAI
recommends to visit a
HYUNDAI authorised repairer/serv-
ice partner.
If you continue to drive with the mal-
function indicator light blinking for a
long time, the DPF system can be
damaged and fuel consumption can
be worsen and the engine durability
can be worsen by oil dilution.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 is high in sulfurs
(above 50 ppm) or contains
unspecified additives, it may
damage the DPF system and
cause the white smoke emis-
sion.

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 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. The Gasoline (P
etrol) 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 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 driv-
en with the GPF Lamp flashing for an
extended period of time, it may dam-
age the GPF system and lower the
fuel economy.

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.

Low urea warning message
(if equipped)The lack warning messages of Urea
appear below Urea 5.4 litre. 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 in
000km or vehicle will not start" with
SCR warning lamp ( ). "xxx
km(mile)" represents the remaining
travel distance 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 at least 4
litres of urea. When "Refill Urea in
000km or vehicle will not start" mes-
sage is displayed, fill up urea at least
6 litres. When "Refill Urea tank or
vehicle will not start" message is dis-
played with SCR warning lamp ( ),
the vehicle can't be restarted once
the engine is turned off by ignition
key. For the above cases, full replen-
ishment is always recommended.
