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 electrical 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
protection.
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 six seconds when the
Engine Start/Stop button is in the ON position.
• The light stays on after illuminating
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 conditions occur. During a frontal collision, sensors will
detect the vehicle’s deceleration. If the
rate of deceleration is high enough, the
control unit will inflate the front air bags.
The front air bags help protect the driver
and front passenger by responding to
frontal impacts in which seat belts alone
cannot provide adequate restraint. When
needed, the side air bags help provide
protection in the event of a side impact
or rollover. •
Air bags are activated (able to inflate
if necessary) when the Engine Start/
Stop button is in the ON position or
approximately within 3 minutes after
ignition off.
• Air bags inflate in the event of certain
frontal or side collisions to help
protect the occupants from serious
physical injury.
• Generally, air bags are designed to
inflate based upon the severity of
a collision, its direction, etc. These
two factors determine whether
the sensors produce an electronic
deployment/inflation signal.
• The front air bags will completely
inflate and deflate in an instant. It is
virtually impossible for you to see the
air bags inflate during an accident. It is
much more likely that you will simply
see the deflated air bags hanging out
of their storage compartments after the collision.

Seats & Safety System
3-44
•
In addition to inflating in certain side
collisions, vehicles equipped with a
rollover sensor, side and curtain air
bags will inflate if the sensing system
detects a rollover.
When a rollover is detected, side and
curtain air bags will remain inflated
longer to help provide protection
from ejection, especially when used in
conjunction with the seat belts.
• To help provide protection, the air
bags must inflate rapidly. The speed
of air bag inflation is a consequence
of extremely short time in which
to inflate the air bag between the
occupant and the vehicle structures
before the occupant impacts those
structures. This speed of inflation
reduces the risk of serious or life-
threatening injuries and is thus a
necessary part of air bag design.
However, the rapid air bag inflation can also cause injuries which can
include facial abrasions, bruises and
broken bones because the inflation
speed also causes the air bags to
expand with a great deal of force.
• There are even circumstances under
which contact with the air bag can
cause fatal injuries, especially if the
occupant is positioned excessively
close to the air bag.
You can take steps to help reduce the
risk of being injured by an inflating air
bag. The greatest risk is sitting too close
to the air bag. An air bag needs space to
inflate. It is recommended that drivers sit
as far as possible between the center of
the steering wheel and the chest while
still maintaining control of the vehicle.
WARNING
To reduce the risk of serious injury or
death from an inflating air bag, take the
following precautions: • NEVER place a child restraint in the
front passenger seat.
Always properly restrain children
under age 13 in the rear seats of the
vehicle.
• Adjust the front passenger’s and
driver’s seats as far to the rear as
possible while allowing you to
maintain full control of the vehicle.
• Hold the steering wheel with
hands at the 9 o’clock and 3 o’clock positions.
• NEVER place anything or anyone
between the air bag and the seat
occupant.
• Do not allow the front passenger
to place their feet or legs on the
dashboard.

“Limp Home” Mode and Related
Procedures
If the immobilizer warning indicator
blinks for five seconds when the ignition
key is turned to the “ON” position,
this indicates the immobilizer system
requires service. The engine cannot be
started without using the procedure
below.
The following procedure describes
how to start the engine using the limp
home function (0, 1, 2, 3 as a sample
password).
NOTICE
You can get a limp home password
when the vehicle is first delivered to
you. If you do not have a password,
consult your authorized HYUNDAI
dealer.
1. To activate the password, turn the ignition key “ON” and “OFF“
according to the digit numbers. The
immobilizer indicator will blink along
with the operation of the ignition
key. For example, turn the ignition
key once for digit number “1”, and
twice for “2”, and so on. For the digit
number “0”, you must cycle the
ignition key 10 times.
2. Wait for 3~10 seconds.
3. You may set the remaining number of digits by following steps 1 and 2.
4. If all of the four password digits have
been successfully entered, turn the
ignition key “ON” and check that the
immobilizer indicator illuminates.
From this time, you have to start your
engine within 30 seconds. If you try
to start your engine after 30 seconds,
your engine will not start.
NOTICE
If the engine stalls while driving in the
“limp home” mode, you can start your
engine within 3 seconds without re-
entering the password.
If the immobilizer indicator blinks for
five seconds, you must re-enter the
password (steps 1~4).
After performing the limp home
activation procedure, consult with your
authorized HYUNDAI dealer as soon as possible.
CAUTION
• If the password is entered incorrectly
three consecutive times, wait for
about one hour to perform the limp
home activation procedure again.

Information
In cold and wet climates, trunk lock and
trunk mechanisms may not work properly
due to freezing conditions.
WARNING
Always be careful to open and close the trunk.
• To prevent serious injury and damage, you should check and keep
your body parts such as hands or
head away from the path of the trunk while closing or opening the trunk.
• Your body parts or an object might be damaged by sharp edges so you
should be careful while opening/closing the trunk or taking the thing
out from the trunk. Especially, a child
can hit the face or head around the
trunk so you should be cautious all the time.
Emergency Trunk Safety Release
Inside the trunk
ODN8059044L
Your vehicle is equipped with an
Emergency Trunk Safety Release lever
located inside the trunk. When someone
is inadvertently locked in the trunk, the
trunk can be opened by moving the lever
in the direction of the arrow and pushing the trunk open.
WARNING
• You and your passengers must be aware of the location of the
Emergency Trunk Safety Release
lever in this vehicle and how to open
the trunk in case you are accidentally
locked in the trunk.
• NEVER allow anyone to occupy the trunk of the vehicle at any time. If the
trunk is partially or totally latched
and the person is unable to get out,
serious injury or death could occur
due to lack of ventilation, exhaust
fumes and rapid heat build-up, or
because of exposure to cold weather
conditions. The trunk is also a highly
dangerous location in the event of a
crash because it is not a protected
occupant space but is a part of the
vehicle’s crush zone.
• Your vehicle should be kept locked and the Smart Key should be kept
out of the reach of children. Parents
should teach their children about the
dangers of playing in trunks.
• Use the release lever for emergencies only.

If the fuel filler door does not open
because ice has formed around it, tap
lightly or push on the door to break the
ice and release the door. Do not pry on the
door. If necessary, spray around the door
with an approved deicer fluid (do not use
radiator antifreeze) or move the vehicle to a warm place and allow the ice to melt. Closing the fuel filler door
1. To install the fuel tank cap, turn it clockwise until it “clicks” one time.
2. Close the fuel filler door until it is latched securely.
WARNING
Gasoline is highly flammable and
explosive. Failure to follow these
guidelines may result in SERIOUS
INJURY or DEATH: • Read and follow all warnings posted
at the gas station.
• Before refueling, note the location of
the Emergency Gasoline Shut-Off, if
available, at the gas station.
• Before touching the fuel nozzle, you
should eliminate the potential build-
up of static electricity by touching
a metal part of the vehicle, a safe
distance away from the fuel filler
neck, nozzle, or other gas source,
with your bare hand.
• Do not use cellular phones while
refueling. Electric current and/or
electronic interference from cellular
phones can potentially ignite fuel
vapors and cause a fire. •
Do not get back into a vehicle
once you have begun refueling.
You can generate a buildup of
static electricity by touching,
rubbing or sliding against any item
or fabric capable of producing
static electricity. Static electricity
discharge can ignite fuel vapors
causing a fire. If you must re-enter
the vehicle, you should once again
eliminate potentially dangerous
static electricity discharge by
touching a metal part of the vehicle,
away from the fuel filler neck, nozzle
or other gasoline source, with your
bare hand.
• When using an approved portable
fuel container, be sure to place the
container on the ground prior to
refueling. Static electricity discharge
from the container can ignite fuel
vapors causing a fire.
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 button to the P (Park) position
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.
• Do not over-fill or top-off your
vehicle tank, which can cause gasoline spillage.
