Petrol engine
Unleaded
For the optimal vehicle performance, we recommend you use unleaded petrol which
has an octane rating of RON (Research Octane Number) 95 / AKI (Anti Knock Index)
91 or higher. You may use unleaded petrol with an octane rating of RON 91-94 / AKI
87-90 but it may result in slight performance reduction of the vehicle. (Do not use
methanol blended fuels)
Your new vehicle is designed to obtain maximum performance with UNLEADED FUEL,
as well as minimise exhaust emissions and spark plug fouling.
CAUTION
NEVER USE LEADED FUEL. The use of leaded fuel is detrimental to the catalytic
converter and will damage the engine control system’s oxygen sensor and affect
emission control.
Never add any fuel system cleaning agents to the fuel tank other than what has
been specified (We recommend that you consult a HYUNDAI authorised repairer for
details.)
WARNING

[Do not “top off” after the nozzle automatically shuts off when refuelling.

[Always check that the fuel cap is installed securely to prevent fuel spillage in the
event of an accident.

Seat belts
Always fasten your seat belt before
starting any trip.
At all times, passengers should sit
upright and be properly restrained.
Infants and small children must be
restrained in appropriate Child Restraint
Systems. Children who have outgrown
a booster seat and adults must be
restrained using the seat belts.
WARNING
Take the following precautions when
adjusting your seat belt:

[NEVER use one seat belt for more
than one occupant.

[Always position the seatback upright
with the lap portion of the seat belt
snug and low across the hips.

[NEVER allow children or small infants
to ride in a passenger’s lap.

[Do not route the seat belt across your
neck, across sharp edges, or reroute
the shoulder strap away from your
body.

[Do not allow the seat belt to become
caught or jammed.
Front seats
The front seat can be adjusted by using
the control lever or switches located on
the outside of the seat cushion. Before
driving, adjust the seat to the proper
position so that you can easily control
the steering wheel, foot pedals and
controls on the instrument panel.
WARNING
Take the following precautions when
adjusting your seat:

[NEVER attempt to adjust the seat
whilst the vehicle is moving. The
seat could respond with unexpected
movement and may cause loss
of vehicle control resulting in an
accident.

[Do not place anything under the front
seats. Loose objects in the driver’s
foot area could interfere with the
operation of the foot pedals, causing
an accident.

[Do not allow anything to interfere
with the normal position and proper
locking of the seatback.

[Do not place a cigarette lighter on
the floor or seat. When you operate
the seat, gas may exit out of the
lighter causing a fire.

[Use extreme caution when picking
small objects trapped under the seats
or between the seat and the centre
console. Your hands might be cut or
injured by the sharp edges of the seat
mechanism.

Seatback angle
OBC3030003R
To recline the seatback:
1. Lean forward slightly and lift up the
seatback lever.
2. Carefully lean back on the seat and
adjust the seatback to the position you
desire.
3. Release the lever and make sure the
seatback is locked in place. (The lever
MUST return to its original position for
the seatback to lock.)Reclining seatback
Sitting in a reclined position when the
vehicle is in motion can be dangerous.
Even when buckled up, the protections
of your restraint system (seat belts
and/or air bags) is greatly reduced by
reclining your seatback.
WARNING
NEVER ride with a reclined seatback
when the vehicle is moving.
Riding with a reclined seatback
increases your chance of serious or
fatal injuries in the event of a collision
or sudden stop.
Drivers and passengers should ALWAYS
sit well back in their seats, properly
belted, and with the seatbacks upright.
Seat belts must be snug against your
hips and chest to work properly. When
the seatback is reclined, the shoulder
belt cannot do its job because it will not
be snug against your chest. Instead, it
will be in front of you.
During an accident, you could be twined
around the seat belt, causing neck or
other injuries.
The more the seatback is reclined,
the greater chance the passenger’s
hips will slide under the lap belt or the
passenger’s neck will strike the shoulder
belt.
