*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.

OLMB033104•
NEVER lean on the door or center console or sit on
one side of the front passenger seat.
ODH035900K •
Do not sit on the passenger seat wearing heavily
padded clothes such as ski wear and hip protector.
ODH035901K •
Do not use car seat accessories such as thick blankets
and cushions which cover up the car seat surface.
OHI038161 •
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
satellite radios which use inverter chargers.
OHI038162 •
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.

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.
ODN8A039055
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.

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.
WARNING
Running out of fuel can expose vehicle
occupants to danger.
You must stop and obtain additional
fuel as soon as possible after the
warning light comes on or when the
gauge indicator comes close to the "E
(Empty)" level.
NOTICE
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire and damage
the catalytic converter. Outside temperature gauge

This gauge indicates the current outside
air temperature by 1°C (1°F).
Temperature range: 40°C ~ 60°C (-40°F ~ 140°F )
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 °C to °F or °F to °C 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 3 seconds
Both the temperature unit on the cluster
LCD display and climate control screen will change.

Warning and Indicator Lights
Information
Make sure that all warning lights are OFF
after starting the engine. If any light is still ON, this indicates a situation that needs attention.
Air Bag Warning Light
This warning light illuminates:
• When you place the ignition switch to the ON position.
- The air bag warning light illuminates for about 6 seconds and then turns
off when all checks have been
performed
• The air bag warning light will remain
illuminated if there is a malfunction
with the Safety Restraint System (SRS)
air bag operation.
In this case, have the vehicle
inspected by an authorized HYUNDAI
dealer.
Seat Belt Warning Light
This warning light informs the driver that
the seat belt is not fastened.
For more information, refer to “Seat
Belts” in chapter 3. Parking Brake & Brake Fluid
Warning Light
This warning light illuminates:
•
When you place the ignition switch to the ON position.
- The parking brake light illuminates for about 3 seconds and will then
turn off once the parking brake is
released.
• Whenever the parking brake is applied.
• Whenever the brake fluid level in the
reservoir is low.
- If the warning light illuminates with the parking brake released, it
indicates that the brake fluid level in
the reservoir is low.
If the brake fluid level in the reservoir is low:
1. Drive carefully to the nearest safe location and stop your vehicle.
2. With the engine stopped, check the brake fluid level immediately
and add fluid as required (For more
information, refer to "Brake Fluid" in
chapter 8) . After adding brake fluid,
check all brake components for fluid
leaks. If a brake fluid leak is found, or
if the warning light remains on, or if
the brakes do not operate properly, do
not drive the vehicle. Have the vehicle
inspected by an authorized HYUNDAI
dealer.
