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.
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.
Do not use gasohol containing more
than 10% 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.
Discontinue using gasohol of any
kind if drivability problems occur.
"E85" fuel is an alternative fuel com-
prised of 85 percent ethanol and 15
percent gasoline, and is manufac-
tured exclusively for use in Flexible
Fuel Vehicles. “E85” is not compati-
ble with your vehicle. Use of “E85”
may result in poor engine perform-
ance and damage to your vehicle's
engine and fuel system. HYUNDAI
recommends that customers do not
use fuel with an ethanol content
exceeding 10 percent.
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.

The SRSCM continually monitors all
SRS components while the Engine

tion 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 (Supplement Restraint
System) air bag warning light on the
instrument panel displays the air bag
symbol depicted in the illustration.
The system checks the air bag elec-
trical system for malfunctions. The
light indicates that there is a potential
malfunction with your air bag system,
which could include your side and
curtain air bags used for rollover pro-
tection.
If your SRS malfunctions, the air
bag may not inflate properly dur-
ing an accident increasing the
risk of serious injury or death.
If any of the following condi-
tions occur, your SRS is mal-
functioning:
The light does not turn on for
approximately six seconds
when the ignition switch is in
the ON position.
The light stays on after illumi-
nating for approximately 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 con-
ditions occur.

sound and the hazard warning lights
will blink continuously if any of the
following occurs:
- A door is opened without using theremote key or smart key.
- The trunk is opened without using the remote key or smart key.
- The engine hood is opened.
The alarm continues for 30 seconds, then the system resets. To turn off

smart key will cause the alarm to
activate.

the hood, the trunk, or any door is
not fully closed. If the system will not
set, check the hood, the trunk, or the
doors are fully closed.
Do not attempt to alter this system or
add other devices to it.Information

sengers have left the vehicle. If the
remaining passenger leaves the
vehicle when the system is armed,
the alarm will be activated.

doors by using the mechanical key
and place the ignition switch in the
ON position (for remote key) or start
the engine (for smart key) by direct-
ly pressing the ignition switch with
