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.

Improperly positioned seat belts may
increase the risk of serious injury
in an accident. Take the following
precautions when adjusting the seat
belt:
• Position the lap portion of the seat
belt as low as possible across your
hips, not on your waist, so that it fits
snugly.
• Position one arm under the shoulder
belt and the other over the belt, as
shown in the illustration.
• Always position the shoulder belt
anchor into the locked position at the
appropriate height.
• NEVER position the shoulder belt
across your neck or face.

WARNING
To reduce the risk of serious injury or
death from an inflating curtain air bag,
take the following precautions:
• All seat occupants must wear
seat belts at all times to help keep
occupants positioned properly.
• Properly secure child restraints as far
away from the door as possible.
• Do not place any objects over the air
bag. Also, do not attach any objects
around the area the air bag inflates
such as the door, side door glass,
front and rear pillar, roof side rail.
• Do not hang other objects except
clothes, especially hard or breakable
objects. In an accident, it may cause
vehicle damage or personal injury.
• Do not allow passengers to lean their
heads or bodies onto doors, put their
arms on the doors, stretch their arms
out of the window, or place objects
between the doors and seats.
• Do not open or repair the side curtain
air bags.

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 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.
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.
• 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.

Proper seated position for OCS
If the “PASSENGER AIR BAG OFF”
indicator is on when an adult is seated
in the front passenger seat, place the
Engine Start/Stop button in the OFF
position and ask the passenger to sit
properly (sitting upright with the seat
back in an upright position, centered
on the seat cushion with their seat belt
on, legs comfortably extended and their
feet on the floor). Restart the engine and
have the person remain in that position.
This will allow the system to detect the
person and to enable the passenger air
bag. If the “PASSENGER AIR BAG OFF”
indicator is still on, ask the passenger to
move to the rear seat.
WARNING
NEVER allow an adult passenger to ride
in the front passenger seat when the
“PASSENGER AIR BAG OFF” indicator
is illuminated. During a collision, the
air bag will not inflate if the indicator
is illuminated. Have your passenger
reposition themselves in the seat. If the
“PASSENGER AIR BAG OFF” indicator
remains illuminated after the passenger
repositions themselves properly
and the vehicle is restarted, have
the passenger move to the rear seat
because the air bag will not inflate.
NOTICE
The “PASSENGER AIR BAG OFF”
indicator generally illuminates for
approximately 4 seconds after the
Engine Start/Stop button is in the ON
position or after the engine is started.
However, if the ignition switch or
Engine Start/Stop button is turned to
the ON position within 3 minutes after
ignition OFF, the indicator does not
illuminate. If the front passenger seat
is occupied, the OCS will then classify
the front passenger after several more
seconds.

Additional Safety Precautions
Passengers should not move out of
or change seats while the vehicle is
moving. A passenger who is not wearing
a seat belt during a crash or emergency
stop can be thrown against the inside of
the vehicle, against other occupants, or
be ejected from the vehicle.
Do not use any accessories on seat
belts. Devices claiming to improve
occupant comfort or reposition the seat
belt can reduce the protection provided
by the seat belt and increase the chance
of serious injury in a crash.
Do not modify the front seats.
Modification of the front seats could
interfere with the operation of the
supplemental restraint system sensing
components or side air bags.
Do not place items under the front
seats. Placing items under the front seats
could interfere with the operation of the
supplemental restraint system sensing
components and wiring harnesses.
Do not cause impact to the doors.
Impact to the doors when the Engine
Start/Stop button is in the ON position
may cause the air bags to inflate.
Modifications to accommodate
disabilities. If you require modification
to your vehicle to accommodate
a disability, contact the HYUNDAI
Customer Connect Center at 800-633-
5151.
Adding equipment to or modifying
your air bag equipped vehicle
If you modify your vehicle by changing
your vehicle’s frame, bumper system,
front end or side sheet metal or ride
height, this may affect the operation of
your vehicle’s air bag system.
Air Bag Warning Labels
OCN7030069N
Air bag warning labels, required by the
U.S. National Highway Traffic Safety
Administration (NHTSA), are attached
to alert the driver and passengers of
potential risks of the air bag system. Be
sure to read all of the information about
the air bags that are installed on your
vehicle in this Owners Manual.
