NOTICE indicates a situation
which, if not avoided, could result
in vehicle damage. Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as mini-
mize exhaust emissions and spark
plug fouling.
Your new vehicle is designed to use
only unleaded fuel having an octane
number ((R+M)/2) of 87 (Research
Octane Number 91) or higher. (Do not
use methanol blended fuels)
To prevent damage to the engine
and engine components, never
add any fuel system cleaning
agents to the fuel tank other than
what has been specified.
Consult an authorized HYUNDAI
dealer for additional information.
Gasoline containing alcohol or
methanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alco-
hol) are being marketed along with or
instead of leaded or unleaded gaso-
line. For example, "E15" is a gasohol
comprised of 15% ethanol and 85%
gasoline.
Do not use gasohol containing more
than 15% ethanol, and do not use
gasoline or gasohol containing any
methanol. Either of these fuels may
cause drivability problems and dam-
age to the fuel system, engine con-
trol system and emission control sys-
tem.
Discontinue using gasohol of any
kind if drivability problems occur.
NOTICE
NOTICE
CAUTION indicates a hazardous
situation which, if not avoided,
could result in minor or moder-
ate injury.
CAUTION
•Do not "top off" after the noz-
zle automatically shuts off
when refueling.
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
WARNING
Page 526 of 557
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Owner’s
Handbook & Warranty Information
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 func-
tion of the emission control systems,
it is recommended that you have
your vehicle inspected and main-
tained by an authorized HYUNDAI
dealer in accordance with the main-
tenance schedule in this manual. For the Inspection and
Maintenance Test (with Electronic
Stability Control (ESC) system)
To prevent the vehicle from mis-
firing during dynamometer test-
ing, turn the Electronic Stability
Control (ESC) system off by
pressing the ESC switch (ESC
OFF light illuminated).
After dynamometer testing is 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 ControlSystem Including Onboard
Refueling Vapor Recovery
(ORVR)
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere. The ORVR system is
designed to allow the vapors from
the fuel tank to be loaded into a can-
ister while refueling at the gas sta-
tion, preventing the escape of fuel
vapors into the atmosphere.

Canister
Fuel 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.
3. Exhaust Emission Control System
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
while maintaining good vehicle per-
formance.
When the engine starts or fails to
start, excessive attempts to restart
the engine may cause damage to the
emission system.
Engine exhaust (carbon monox-
ide) precautions
Carbon monoxide can be present
with other exhaust fumes. If you
smell exhaust fumes of any kind in
your vehicle, drive with all the win-
dows fully open. Have your vehicle
checked and repaired immediate-
ly.
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
on this page to avoid CO poi-
soning.
