Hybrid Battery Cooling Duct
The hybrid battery cooling duct is
located on the left side of the rear
seats. The cooling duct cools down
the hybrid battery. When the hybrid
battery cooling duct is blocked, the
hybrid battery may be overheated.Do not obstruct the cooling duct with
any other objects.
Information
Clean the cooling duct for the hybrid bat-
tery with a dry cloth on a regular basis.
i
(Continued)

Do not put any objects into
the cooling duct of the hybrid
battery. Doing so may cause
loss of cooling duct volume to
the hybrid battery. When the
cooling duct is blocked with
any objects, immediately con-
tact your HYUNDAI dealer.
Never place a container of liq-
uid on or near the cooling
duct. If the liquid spills, the
hybrid battery located in the
luggage compartment may be
damaged.
Secure all loads in the lug-
gage compartment to pre vent
them from being tossed about
before driving. When a sharp
or heavy load strike with a
strong impact or pierce the
interior luggage compartment
wall, the hybrid battery sys-
tem may be damaged, deterio-
rating its performance.
Never clean the cooling duct
of the hybrid battery with a
wet cloth. If any water enters
in the cooling duct of the
hybrid battery, the hybrid bat-
tery may cause an electric
shock, resulting in a serious
damage, an injury or a death.
The hybrid battery is com-
posed of lithium-ion polymer.
If the hybrid battery is improp-
erly handled, it is dangerous
to the environment. Also it
may cause electrical shock
and severe burns, resulting in
a serious injury or a death.
Do not spill liquid over the
cooling duct of the hybrid bat-
tery. Doing so is very danger-
ous. It may cause electric
shock or serious injury.
Do not cover the cooling duct
with objects.

Introduction
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 perform-
ance 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 min-
imise exhaust emissions and spark
plug fouling.NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental to
the catalytic converter and will
damage the engine control sys-
tem’s oxygen sensor and affect
emission control.
Never add any fuel system clean-
ing agents to the fuel tank other
than what has been specified (We
recommend that you consult a
HYUNDAI authorised repairer for
details.)

5. To use the rear seat, lift and push the seatback rearward.
Push the seatback firmly until it
clicks into place. Make sure the
seatback is locked in place.
OAE036066L
Do not place objects in the rear
seats, since they cannot be
properly secured and may hit
vehicle occupants in a collision
causing serious injury or death.
WARNING
When returning the rear seat-
back from a folded to an upright
position, hold the seatback and
return it slowly. Ensure that the
seatback is completely locked
into its upright position by
pushing on the top of the seat-
back. In an accident or sudden
stop, the unlocked seatback
could allow cargo to move for-
ward with great force and enter
the passenger compartment,
which could result in serious
injury or death.

Safety system of your vehicle
This section describes how to use the
seat belts properly. It also describes
some of the things not to do when
using seat belts.
Seat belt safety precautions
Always fasten your seat belt and
make sure all passengers have fas-
tened their seat belts before starting
any trip. Air bags (if equipped) are
designed to supplement the seat belt
as an additional safety device, but
they are not a substitute. Most coun-
tries require all occupants of a vehicle
to wear seat belts.

Seat belts must be used by ALL
passengers whenever the vehi-
cle is moving. Take the following
precautions when adjusting and
wearing seat belts:
Children under the age of 13
should be properly restrained
in the rear seats.
Never allow children to ride in the front passenger seat,
unless the air bag is deacti-
vated. If a child is seated in
the front passenger seat,
move the seat as far back as
possible and properly restrain
them in the seat.
NEVER allow an infant or child
to be carried on an occupant’s
lap.
NEVER ride with the seatback
reclined when the vehicle is
moving.
Do not allow children to share
a seat or seat belt.
(Continued)
WARNING (Continued)
Do not wear the shoulder belt
under your arm or behind your
back.
Never wear a seat belt over
fragile objects. If there is a sud-
den stop or impact, the seat
belt can damage it.
Do not use the seat belt if it is
twisted. A twisted seat belt
will not protect you properly
in an accident.
Do not use a seat belt if the
webbing or hardware is dam-
aged.
Do not latch the seat belt into
the buckles of other seats.
NEVER unfasten the seat belt
whilst driving. This may cause
loss of vehicle control result-
ing in an accident.
Make sure there is nothing in
the buckle interfering with the
seat belt latch mechanism.
This may prevent the seat belt
from fastening securely.(Continued)

Larger children
Children under age 13 and who are
too large for a booster seat should
always occupy the rear seat and use
the available lap/shoulder belts. A
seat belt should lie across the upper
thighs and be snug across the shoul-
der and chest to restrain the child
safely. Check belt fit periodically. A
child's squirming could put the belt
out of position. In the event of an acci-
dent, children are afforded the best
safety restrained by a proper Child
Restraint System in the rear seats.
If a larger child over age 13 must be
seated in the front seat, the child
must be securely restrained by the
available lap/shoulder belt and the
seat should be placed in the rear-
most position.
If the shoulder belt portion slightly
touches the child’s neck or face, try
placing the child closer to the centre
of the vehicle. If the shoulder belt still
touches their face or neck, they need
to be returned to an appropriate
booster seat in the rear seat.
Seat belt use and injured people
A seat belt should be used when an
injured person is being transported.
Consult a physician for specific rec-
ommendations.
One person per belt
Two people (including children) should
never attempt to use a single seat belt.
This could increase the severity of
injuries in case of an accident.
Do not lie down
Sitting in a reclined position when
the vehicle is in motion can be dan-
gerous. Even when buckled up, the
protections of your restraint system
(seat belts and/or air bags) is greatly
reduced by reclining your seatback.
Seat belts must be snug against your
hips and chest to work properly.
During an accident, you could be
thrown into the seat belt, causing
neck or other injuries.
Always make sure larger chil-
dren’s seat belts are worn and
properly adjusted.
NEVER allow the shoulder
belt to contact the child’s
neck or face.
Do not allow more than one
child to use a single seat belt.
WARNING

Safety system of your vehicle
Our recommendation:
Children always in the rear
Children under age 13 should always
ride in the rear seats and must
always be properly restrained to min-
imise the risk of injury in an accident,
sudden stop or sudden manoeuvre.
According to accident statistics, chil-
dren are safer when properly restrained
in the rear seats than in the front
seat. Children too large for a Child
Restraint System must use the seat
belts provided.Most countries have regulations which
require children to travel in approved
Child Restraint Systems.
The laws governing the age or
height/weight restrictions at which seat
belts can be used instead of Child
Restraint System differs among coun-
tries, so you should be aware of the
specific requirements in your country,
and where you are travelling.
Child Restraint Systems must be
properly installed in the vehicle seat.
Always use a commercially available
Child Restraint System that meets the
requirements of your country.
Child Restraint System (CRS)
Infants and younger children must be
restrained in an appropriate rearward-
facing or forward-facing CRS that has
first been properly secured to the seat
of the vehicle. Read and comply with
the instructions for installation and use
provided by the manufacturer of the
Child Restraint System.

Booster seats
A booster seat is a Child Restraint
System designed to improve the fit of
the vehicle’s seat belt system. A boost-
er seat positions the seat belt so that it
fits properly over the stronger parts of
your child’s body. Keep your children in
booster seats until they are big
enough to fit in a seat belt properly.
For a seat belt to fit properly, the lap
belt must lie comfortable across the
upper thighs, not the stomach. The
shoulder belt should lie comfortable
across the shoulder and chest and
not across the neck or face. Children
under age 13 must always be proper-
ly restrained to minimise the risk of
injury in an accident, sudden stop or
sudden manoeuvre.
Installing a Child Restraint
System (CRS)After selecting a proper Child Restraint
System for your child and checking
that the Child Restraint System fits
properly on the seating position, there
are three general steps for a proper
installation:
Properly secure the Child Restraint
System to the vehicle.
All Child
Restraint Systems must be secured
to the vehicle with the lap belt or lap
part of a lap/shoulder belt or with
the ISOFIX top-tether and/or ISOFIX
anchorage and/or with the support
leg.
Make sure the Child Restraint
System is firmly secured. After
installing a Child Restraint System
to the vehicle, push and pull the
seat forward and from side-to-side
to verify that it is securely attached
to the seat. A Child Restraint
System secured with a seat belt
should be installed as firmly as
possible. However, some side-to-
side movement can be expected.
Before installing your Child
Restraint System always:
Read and follow the instructions
provided by the manufacturer of
the Child Restraint System.
Failure to follow all warnings
and instructions could increase
the risk of the SERIOUS INJURY
or DEATH if an accident occurs.
WARNING
If the vehicle head restraint pre-
vents proper installation of a
Child Restraint System, the
head restraint of the respective
seating position shall be read-
justed or entirely removed.
