Air bag inflation conditions
ODN8039048L
Front air bags
Front air bags are designed to inflate
in a frontal collision depending on the
severity of impact of the front collision.
ODN8H030049N
ODN8039050
Side and curtain air bags
Side and curtain air bags are designed
to inflate when an impact is detected by
side collision sensors depending on the
severity of impact resulting from a side
impact collision.
Although the driver’s and front
passenger’s air bags are designed to
inflate only in frontal collisions, they also
may inflate in other types of collisions
if the front impact sensors detect a
sufficient impact. Side and curtain air
bags are designed to inflate only in side
impact collisions or rollover situations,
but they may inflate in other collisions
if the side impact sensors detect a
sufficient impact.
If the vehicle chassis is impacted by
bumps or objects on unimproved roads,
the air bags may deploy. Drive carefully
on unimproved roads or on surfaces not
designed for vehicle traffic to prevent
unintended air bag deployment.
Air bag non-inflation conditions
ODN8039051L
In certain low-speed collisions the air
bags may not deploy. The air bags are
designed not to deploy in such cases
because they may not provide benefits
beyond the protection of the seat belts.

Safety System
3-56
ODN8039052L
Front air bags are not designed to inflate
in rear collisions, because occupants
are moved backward by the force of the
impact. In this case, inflated air bags
would not provide any additional benefit.
ODN8H030053N
Front air bags may not inflate in side
impact collisions, because occupants
move in the direction of the collision,
and thus in side impacts, front air bag
deployment would not provide additional
occupant protection.
However, side and curtain air bags may
inflate depending on the severity of
impact.
ODN8039059
In an angled collision, the force of impact
may direct the occupants in a direction
where the air bags would not be able to
provide any additional benefit, and thus
the sensors may not deploy any air bags.
ODN8039054
Just before impact, drivers often brake
heavily. Such heavy braking lowers the
front portion of the vehicle causing it
to “ride” under a vehicle with a higher
ground clearance. Air bags may not
inflate in this “underride” situation
because deceleration forces that are
detected by sensors may be significantly
reduced by such “underride” collisions.

03
3-57
ODN8A039088
Front air bags may not inflate in rollover
accidents because air bag deployment
may not provide protection to the
occupants.
However, side and curtain air bags may
inflate when the vehicle is rolled over by
a side impact collision.
ODN8H030055N
Air bags may not inflate if the vehicle
collides with objects such as utility poles
or trees, where the point of impact is
concentrated and the collision energy is
absorbed by the vehicle structure.
SRS Care
The SRS is virtually maintenance-free
and there are no parts you can safely
service by yourself. If the SRS air bag
warning light does not illuminate when
the ignition switch is in the ON position,
or continuously remains on, have your
vehicle immediately inspected by an
authorized HYUNDAI dealer.
Any work on the SRS system, such as
removing, installing, repairing, or any
work on the steering wheel, the front
passenger’s panel, front seats and roof
rails must be performed by an authorized
HYUNDAI dealer. Improper handling of
the SRS system may result in serious
personal injury.
WARNING
To reduce the risk of serious injury or
death, take the following precautions:
• Do not attempt to modify or
disconnect the SRS components or
wiring, including the addition of any
kind of badges to the pad covers or
modifications to the body structure.
• Do not place objects over or near
the air bag modules on the steering
wheel, instrument panel, or the front
passenger’s panel above the glove box.
• Clean the air bag pad covers with
a soft cloth moistened with plain
water. Solvents or cleaners could
adversely affect the air bag covers
and proper deployment of the
system.
• Always have inflated air bags
replaced by an authorized HYUNDAI
dealer.
• If components of the air bag system
must be discarded, or if the vehicle
must be scrapped, certain safety
precautions must be observed.
Consult an authorized HYUNDAI
dealer for the necessary information.
Failure to follow these precautions
could increase the risk of personal
injury.

Safety System
3-58
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
ODN8A039057
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.

Instrument Cluster Control
Adjusting instrument cluster
illumination
ODN8A059337
When the vehicle's parking lamps or
headlamps are on, press the illumination
control button to adjust the brightness of
the instrument panel illumination.
When pressing the illumination control
button, the interior switch illumination
ntensity is also adjustable.
• The brightness of the instrument
panel illumination is displayed.
• If the brightness reaches the
maximum or minimum level, a chime
will sound.
WARNING
Never adjust the instrument cluster
while driving. Doing so could lead to
driver distraction which may cause an
accident and lead to vehicle damage,
serious injury, or death.
Gauges and Meters
Speedometer
„„Type A, B„„Type C
OLX2048102LODN8049004L
The speedometer indicates the speed of
the vehicle and is calibrated in miles per
hour (MPH) and/or kilometers per hour
(km/h).
Power gauge
„„Type A, B„„Type C
ODN8H049032ODN8H040033N
The power gauge indicates whether the
current driving condition is fuel efficient
or not.
• CHARGE : Shows that the energy
made by the vehicle is being
converted to electrical energy.
(Regenerated energy)
• ECO : Shows that the vehicle is being
driven in an Eco-friendly manner.
• POWER : Shows that the vehicle is
exceeding the Eco-friendly range.

Information
Accordance to the power gauge area
the“EV” indicator comes on or off.
-“EV” indicator ON : Vehicle is driven
using the electric motor or the gasoline
engine is stopped.
-“EV” indicator OFF : Vehicle is driven
using the gasoline engine.
Hybrid battery SOC (State of Charge)
gauge
„„Type A, B„„Type C
ODN8H049034ODN8H040035N
This gauge indicates the remaining
hybrid battery power. If the SOC is near
the “0 or L (Low)” level, the vehicle
automatically operates the engine to
charge the battery.
However, if the Service Indicator (
)
and Malfunction Indicator Lamp (MIL)
(
) turn on when the SOC gauge is near
the “0 or L (Low)” level, we recommend
the vehicle be checked by an authorized
HYUNDAI dealer.
NOTICE
Never try to start the vehicle if the fuel
tank is empty. In this condition, the
engine cannot charge the high voltage
battery of the hybrid system. If you
try to start the vehicle when the fuel
is empty, the high voltage battery will
become discharged and be damaged.
Fuel gauge
„„Type A, B
ODN8A049040
„„Type C
ODN8A049007This gauge indicates the approximate
amount of fuel remaining in the fuel tank.
