*1 : The system judges a person of adult size as an adult. When a smaller adult sits in the
front passenger seat, the system may recognize him/her as a child depending on his/her
physique and posture.
*2 : Do not allow children to ride in the front passenger seat. When a larger child who has
outgrown a child restraint system sits in the front passenger seat, the system may
recognize him/her as an adult depending upon his/her physique or sitting position.
*3 : Never install a child restraint system on the front passenger seat.
*4 : The PASSENGER AIR BAG “OFF” indicator may turn on or off when a child above 12
months to 12 years old (with or without child restraint system) sits in the front passenger
seat. This is a normal condition.

• Do not place electronic devices such as laptops, DVD
player, or conductive materials such as water bottles
on the passenger seat.
• Do not use electronic devices such as laptops and

OHI038162OHI038162
• If large quantity of liquid has been spilled on the
passenger seat, the air bag warning light may
illuminate or malfunction.
Therefore, make sure the seat has been completely
dried before driving the vehicle.
• Do not place sharp objects on the front passenger seat. These may damage the
occupant detection system, if they puncture the seat cushion.
• Do not place any items under the front passenger seat.
• When changing or replacing the seat or seat cover, use original items only.
The OCS has been developed based on using original HYUNDAI car seats only.
Altering or changing the authentic parts may result in system malfunction and
increase risk of injury when in collision. Any of the above could interfere with the
proper operation of the OCS sensor thereby increasing the risk of an injury in an
accident.

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.
ODN8A039055ODN8A039055
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.

Engine coolant temperature gauge
ODN8A049041ODN8A049041
ODN8A049006ODN8A049006This gauge indicates the temperature
of the engine coolant when the ignition
switch is in the ON position.
NOTICE
If the gauge pointer moves beyond
the normal range area toward the "H"
position, it indicates overheating that
may damage the engine.
Do not continue driving with an
overheated engine. If your engine
overheats, refer to "If the Engine
Overheats" in chapter 7.
WARNING
Never remove the radiator cap or
reservoir cap when the engine is hot.
The engine coolant is under pressure
and could severely burn. Wait until the
engine is cool before adding coolant to
the reservoir.
Fuel gauge
ODN8A049040ODN8A049040
ODN8A049007ODN8A049007This gauge indicates the approximate
amount of fuel remaining in the fuel tank.
Information
• The fuel tank capacity is given in
chapter 2.
• The fuel gauge is supplemented by
a low fuel warning light, which will
illuminate when the fuel tank is nearly
empty.
• On inclines or curves, the fuel gauge
pointer may fluctuate or the low fuel
warning light may come on earlier than
usual due to the movement of fuel in
the tank.

Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire and damage
the catalytic converter.

Note that the temperature indicated
on the LCD display may not change
as quickly as the outside temperature
(there may be a slight delay before the
temperature changes.) You can change the temperature unit
from °F to °C or °C to °F in the User
Settings mode in the cluster:
- Go to User Settings Mode → Other → Temperature Unit.
For vehicles equipped with Automatic
Climate Control, you can also:
- Press and hold the AUTO and OFF buttons on the climate control unit for
