Gasoline engine
Unleaded
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)
Your new vehicle is designed to obtain maximum performance with UNLEADED FUEL,
as well as minimize exhaust emissions and spark plug fouling.
NOTICE
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.
WARNING

[Do not “top off” after the nozzle automatically shuts off when refueling.

[ Always check that the fuel cap is installed securely to prevent fuel spillage in the
event of an accident.
Gasoline containing alcohol and methanol
Gasohol, a mixture of gasoline and ethanol (also known as grain alcohol) are being
marketed along with or instead of leaded or unleaded gasoline. 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 damage to the fuel system, engine control system and emission control system.
Discontinue using gasohol of any kind if drivability problems occur.
“E85” fuel is an alternative fuel comprised of 85 percent ethanol and 15 percent
gasoline, and is manufactured exclusively for use in Flexible Fuel Vehicles. “E85” is
not compatible with your vehicle. Use of “E85” may result in poor engine performance
and damage to your vehicle’s engine and fuel system. HYUNDAI recommends that
customers do not use fuel with an ethanol content exceeding 15 percent.
NOTICE
To prevent damage to your vehicle’s engine and fuel system:

[Never use gasohol which contains methanol.

[ Never use gasohol containing more than 15% ethanol.

[ Never use leaded fuel or leaded gasohol.

[ Never use “E85” fuel.
Your New Vehicle Limited Warranty does not cover damage to the fuel system or any
performance problems caused by the use of “E85” fuel.

Vehicle Information, Consumer Information and Reporting Safety Defects2-14
Recommended SAE viscosity number
CAUTION
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 damaged.
Engine oil viscosity (thickness) has an effect on fuel economy and cold weather
operating (engine start and engine oil flowability). Lower viscosity engine oils can
provide better fuel economy and cold weather performance, however, higher viscosity
engine oils are required for satisfactory 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 recommended oil viscosity from
the chart.

the engine oil and engine oil filter must be replaced at every 5,000 miles.
An engine oil displaying this API Certification Mark conforms to
the international Lubricant Specification Advisory Committee
(ILSAC). It is recommended to only use engine oils that uphold
this API Certification Mark.

How does the air bags system
operate?
OTMH030008N
The SRS consists of the following
components:
(1) Driver's front air bag module
(2) Passenger's front air bag module
(3) Side air bag modules
(4) Curtain air bag modules
(5) Retractor pre-tensioner
(6) Air bag warning light
(7) SRS control module (SRSCM)/ Rollover sensor
(8) Front impact sensors
(9) Side impact sensors
(10) Side pressure sensors
(11) Seat belt buckle sensor
(12) Emergency fastening device system
(13) Occupant classification system
The SRSCM continually monitors all SRS
components while the ignition switch
is ON to determine if a crash impact
is severe enough to require air bag
deployment or pre-tensioner seat belt
deployment.
SRS warning light
The SRS (Supplemental Restraint System)
air bag w
arning light on the instrument
panel displays the air bag symbol
depicted in the illustration. The system
checks the air bag electrical system for
malfunctions. The light indicates that
there is a potential problem with your
air bag system, which could include
your side and/or curtain air bags used
for rollover protection (if equipped with
rollover sensor).
WARNING
If your SRS malfunctions, the air bag
may not inflate properly during an
accident, increasing the risk of serious
injury or death.
If any of the following conditions occur,
your SRS is malfunctioning:

[ The light does not turn on for
approximately three to six seconds
when the Engine Start/Stop button is
in the ON position.

[ The light stays on after illuminating
for approximately three to six
seconds.

[ The light comes on while the vehicle
is in motion.

[ The light blinks when the engine is
running.
Have an authorized HYUNDAI dealer
inspect the SRS as soon as possible if
any of these conditions occur.

on may cause engine failure.
Information
When engine oil pressure decreases due to
insufficient engine oil, etc., the Engine Oil
Pressure warning light will illuminate. In
addition, the enhanced engine protection
system which limits engine power will
be activated. If the engine oil pressure is
restored, the Engine Oil Pressure warning
light and the enhanced engine protection
system will turn off. However, for gasoline
2.5 turbo engine and 2.5 gdi engine, when
the engine oil pressure is restored, the
warning light and the enhanced engine
protection system will turn off after the
engine is restarted.
NOTICE
