Maintenance
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 a HYUNDAI
authorised repairer. Take extreme care,
as it is difficult to restore the quality
after the repair.

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 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.

Corrosion protection
3URWHFWLQJ\RXUYHKLFOHIURPFRUUR
VLRQ
By using the most advanced design
and construction practices to combat
corrosion, we produces vehicles of the
highest quality. However, this is only
part of the job. To achieve the long-term
corrosion resistance your vehicle can
deliver, the owner’s cooperation and
assistance is also required.
&RPPRQFDXVHVRIFRUURVLRQ
The most common causes of corrosion
on your vehicle are:

[Road salt, dirt and moisture that is
allowed to accumulate underneath the
vehicle.

[Removal of paint or protective
coatings; by stones, gravel, abrasion
or minor scrapes and dents which
leave unprotected metal exposed to
corrosion.
+LJKFRUURVLRQDUHDV
If you live in an area where your vehicle
is regularly exposed to corrosive
materials, corrosion protection is
particularly important. Some of the
common causes of accelerated
corrosion are road salts, dust control
chemicals, ocean air and industrial
pollution.

9-84
Maintenance
0RLVWXUHEUHHGVFRUURVLRQ
Moisture creates the conditions in
which corrosion is most likely to occur.
For example, corrosion is accelerated
by high humidity, particularly when
temperatures are just above freezing. In
such conditions, the corrosive material is
kept in contact with the vehicle surfaces
by moisture that is slow to evaporate.
Mud is particularly corrosive because
it is slow to dry and holds moisture in
contact with the vehicle. Although the
mud appears to be dry, it can still retain
moisture and promote corrosion.
High temperatures can also accelerate
corrosion of parts that are not properly
ventilated so the moisture can be
dispersed. For all these reasons, it is
particularly important to keep your
vehicle clean and free of mud or
accumulations of other materials. This
applies not only to the visible surfaces
but particularly to the underside of the
vehicle.
7RKHOSSUHYHQWFRUURVLRQ
You can help prevent corrosion from
getting started by observing the
following:
Keep your vehicle clean
The best way to prevent corrosion is
to keep your vehicle clean and free of
corrosive materials. Attention to the
underside of the vehicle is particularly
important.

[If you live in a high-corrosion area —
where road salts are used, near the
ocean, areas with industrial pollution,
acid rain, etc.—, you should take extra
care to prevent corrosion. In winter,
hose off the underside of your vehicle
at least once a month and be sure to
clean the underside thoroughly when
winter is over.

[When cleaning underneath the
vehicle, give particular attention to the
components under the fenders and
other areas that are hidden from view.
Do a thorough job; just dampening the
accumulated mud rather than washing
it away will accelerate corrosion rather
than prevent it. Water under high
pressure and steam are particularly
effective in removing accumulated
mud and corrosive materials.

[When cleaning lower door panels,
rocker panels and frame members, be
sure that drain holes are kept open so
that moisture can escape and not be
trapped inside to accelerate corrosion.

Keep your garage dry
Don’t park your vehicle in a damp,
poorly ventilated garage. This creates
a favorable environment for corrosion.
This is particularly true if you wash your
vehicle in the garage or drive it into the
garage when it is still wet or covered
with snow, ice or mud. Even a heated
garage can contribute to corrosion
unless it is well ventilated so moisture is
dispersed.
Keep paint and trim in good condition
Scratches or chips in the finish should
be covered with “touch-up” paint as
soon as possible to reduce the possibility
of corrosion. If bare metal is showing
through, the attention of a qualified
body and paint shop is recommended.
Bird droppings : Bird droppings are
highly corrosive and may damage
painted surfaces in just a few hours.
Always remove bird droppings as soon
as possible.
Don’t neglect the interior
Moisture can collect under the floor
mats and carpeting to cause corrosion.
Check under the mats periodically to be
sure the carpeting is dry. Use particular
care if you carry fertilizers, cleaning
materials or chemicals in the vehicle.
These should be carried only in proper
containers and any spills or leaks should
be cleaned up, flushed with clean water
and thoroughly dried.
Interior care
Interior general precautions
Prevent chemicals such as perfume,
cosmetic oil, sun cream, hand cleaner
and air freshener from contacting the
interior parts because they may cause
damage or discolouration. If they do
contact the interior parts, wipe them off
immediately.
See the instructions that follow for the
proper way to clean vinyl.
NOTICE
Never allow water or other liquids
to come in contact with electrical/
electronic components inside the
vehicle as this may damage them.
NOTICE
When cleaning leather products
(steering wheel, seats etc.), use neutral
detergents or low alcohol content
solutions. If you use high alcohol
content solutions or acid/alkaline
detergents, the colour of the leather
may fade or the surface may get
stripped off.

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 it.
Cleaning the interior window glass
If the interior glass surfaces of the
vehicle become fogged (that is, covered
with an oily, greasy or waxy film), they
should be cleaned with glass cleaner.
Follow the directions on the glass
cleaner container.

Maintenance
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
emission regulations.
There are three emission control systems
which are 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 car
inspected and maintained by a HYUNDAI
authorised repairer in accordance
with the maintenance schedule in this
manual.
NOTICE

(ESC) system off by pressing the ESC
switch.

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
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 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.

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.
Petrol Particulate Filter (GPF)
(if equipped)
The Petrol 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 Petrol Particulate Filter (GPF) Lamp
stops illuminating, when the driving
speed exceeds 80 km/h (50 mph) with
the engine at 1,500- 4,000 rpm and the
gear in the 3rd position or above for
approximately 30 minutes.When the GPF lamp starts to blink or
the waning 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 a HYUNDAI
authorised repairer.
With the GPF lamp blinking for an
extended period of time, it may damage
the GPF system and lower the fuel
economy.
WARNING
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 additives, they
may damage the GPF system and cause
exhaust emission problems.
