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.

9. Side pressure sensors
10. Emergency Fastening DeviceSystem
11. Occupant classification system
The SRSCM (Supplemental Restraint
System Control Module) continually
monitors all SRS components while
the ignition switch is in the ON position
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 Engine Start/Stop
button 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.

Electric Power Steering (EPS)
The system assists you with steering
the vehicle. If the vehicle is turned off
or if the power steering system
becomes inoperative, you may still
steer the vehicle, but it will require
increased steering effort.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the system
checked by an authorized HYUNDAI
dealer.
Information
The following symptoms may occur dur-
ing normal vehicle operation:
• The steering effort may be high imme-
diately after placing the ignition switch
in the ON position.
This happens as the system performs
the EPS system diagnostics. When the
diagnostics are completed, the steering
wheel will return to its normal condi-
tion.
• A click noise may be heard from the EPS relay after the ignition switch is in
the ON or LOCK/OFF position.
• Motor noise may be heard when the vehicle is at a stop or at a low driving
speed.
• When you operate the steering wheel in low temperatures, abnormal noise
may occur. If the temperature rises,
the noise will disappear. This is a nor-
mal condition.
• When an error is detected from the EPS, the steering effort assist function
will not be activated in order to pre-
vent fatal accidents. Instrument clus-
ter warning lights may be on or the
steering effort may be high. When the
following symptoms occur, immediate-
ly drive the vehicle to a safe area and
check it.
i
If the Electric Power Steering
System does not operate nor-
mally, the warning light ( ) will
illuminate on the instrument
cluster. You may steer the vehi-
cle, but it will require increased
steering efforts. Take your vehi-
cle to an authorized HYUNDAI
dealer and have the system
checked as soon as possible.
CAUTION
The Theft Alarm System will not set if
the hood, the liftgate, or any door is
not fully closed. If the system will not
set, check the hood, the liftgate, or the
doors are fully closed.
Do not attempt to alter this system or
add other devices to it.
Information
• Do not lock the doors until all pas-
sengers have left the vehicle. If the
remaining passenger leaves the
vehicle when the system is armed,
the alarm will be activated.
• If the vehicle is not disarmed with the remote key or smart key, open
the 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
directly pressing the ignition switch
with the smart key.
• If the system is disarmed by unlock- ing the vehicle, but neither a door or
the liftgate is opened within 30 sec-
onds, the doors will relock and the
system will rearm automatically.

Information
Make sure to refuel your vehicle
according to the "Fuel Requirements"
suggested in the Introduction chapter.
Do not spill fuel on the exteriorsurfaces of the vehicle. Any type
of fuel spilled on painted sur-
faces may damage the paint.
If the fuel filler cap requires replacement, use only a genuine
HYUNDAI cap or the equivalent
specified for your vehicle. An
incorrect fuel filler cap can
result in a serious malfunction
of the fuel system or emission
control system.
NOTICE
i(Continued)
Once refueling has begun,
contact between your bare
hand and the vehicle should
be maintained until the filling
is complete.
Use only approved portable
plastic fuel containers designed
to carry and store gasoline.
When refueling, always move
the shift lever to the P (Park)
position (for automatic transmis-
sion/
dual clutch transmission)
or first gear or R (Reverse, for
manual transmission), set the
parking brake, and place the
ignition switch to the LOCK/OFF
position. Sparks produced by
electrical components related to
the engine can ignite fuel vapors
causing a fire.
Do not use matches or a
lighter and do not smoke or
leave a lit cigarette in your
vehicle while at a gas station,
especially during refueling.
(Continued)
(Continued)
Do not over-fill or top-off your
vehicle tank, which can cause
gasoline spillage.
If a fire breaks out during refu-
eling, leave the vicinity of the
vehicle, and immediately con-
tact the manager of the gas
station and then contact the
local fire department. Follow
any safety instructions they
provide.
If pressurized fuel sprays out,
it can cover your clothes or
skin and thus subject you to
the risk of fire and burns.
Always remove the fuel cap
carefully and slowly. If the cap
is venting fuel or if you hear a
hissing sound, wait until the
condition stops before com-
pletely removing the cap.
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
