$$!!"#"#$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 sys-
tem
(2) Evaporative emission control sys- tem
(3) Exhaust emission control system
In order to assure the proper function
of the emission control systems, it is
recommended that you have your
car inspected and maintained by an
authorized HYUNDAI dealer in
accordance with the maintenance
schedule in this manual.
1. Crankcase emission control systemThe 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 controlsystemThe Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.CanisterFuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in
the canister are drawn into the surge
tank through the purge control sole-
noid 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.

OOperating precautions for catalytic
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 engine.
• 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 ignition off and
descending steep grades in gear
with the ignition 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
authorized HYUNDAI dealer. • Avoid driving with a extremely low
fuel level. Running out of fuel could
cause the engine to misfire, dam-
aging the catalytic converter.
Failure to observe these precautions
could result in damage to the catalyt-
ic converter and to your vehicle.
Additionally, such actions could void
your warranties.
Fire•
A hot exhaust system can ignite
flammable items under your
vehicle. Do not park, idle, or
drive the veh icle over or near
flammable objects, such as
grass, vegetation, paper,
leaves, etc.
•
The exhaust system and catalyt-
ic system are very hot while the
engine is running or immediate-
ly afte r the engine is turned off.
Keep away from the exhaust
system and catalytic, you may
get burned. Also, do not remove
the heat sink around the
exhaust system, do not seal the
bottom of the vehicle or do not
coa t the vehicle for corrosion
control. It may present a fire risk
under certain conditions.

To help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality.
The correct lubricants also help promote engine efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.

*\f : Refer to the recommended SAE viscosity numbers on the next page.
*2: Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel economy by reducing
the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure in everyday driving, but in a year’s
time, they can offer significant cost and energy savings.
*3 : If the recommended engine oil is not available in your country, you are able to use API SL/ / ILSAC GF\b3 or ACEA A3.
*4 : If the recommended engine oil is not available in your country, you are able to use engine oil above API CH\b4.
*5: We recommend that you use the engine oils approved by HYUNDAI Motor India Ltd. We recommend that you consult an authorized HYUNDAI
dealer for details

Recommended SAE viscosity
numberEngine oil viscosity (thickness) has
an effect on fuel economy and cold
weather operating (engine start and
engine oil flowability). Lower viscosi\b
ty engine oils can provide better fuel
economy and cold weather perform\b
ance, however, higher viscosity
engine oils are required for satisfac\b
tory lubrication in hot weather. Using oils of any viscosity other than
those recommended could result in
engine damage.
When choosing an oil, consider the
range of temperature your vehicle
will be operated in before the next oil
change. Proceed to select the rec\b
ommended oil viscosity from the
chart.
Always be sure to clean the area
around any filler plug, drain plug,
or dipstick before checking or
draining any lubricant. This is
especially important in dusty or
sandy areas and when the vehicle
is used on unpaved roads.
Cleaning the plug and dipstick
areas will prevent dirt and grit from
entering the engine and other
mechanisms that could be dam\b
aged.
