Maintenance
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 bright-
metal parts from corrosion, apply a
coating of wax or chrome preser-
vative 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, acceler-
ated 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 under-
body and wheel openings with luke-
warm 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.After washing the vehicle, test
the brakes whilst driving slowly
to see if they have been affected
by water. If braking performance
is impaired, dry the brakes by
applying them lightly whilst
maintaining a slow forward
speed.WARNING

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.
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.
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.

Maintenance
Operating precautions for cat-
alytic converters (if equipped)Your vehicle is equipped with a cat-
alytic converter emission control
device.
Therefore, the following precautions
must be observed:
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 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 an
authorised HYUNDAI dealer.
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.
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 catalytic
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
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 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 oxidisation
process does not occur, and the
Diesel Particulate Filter (DPF) Lamp
( ) Illuminates.The DPF Lamp stops illuminating,
when the driving speed exceeds 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 an
authorised HYUNDAI dealer.
When the vehicle is continuously driv-
en with the DPF Lamp flashing for an
extended period of time, it may dam-
age the DPF system and lower the
fuel economy.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 unspeci-
fied additives, they may damage
the DPF system and cause white
smoke emissions.
