A020201AUN-EADiesel fuel
Diesel engine must be operated only on
commercially available diesel fuel that
complies with EN 590 or comparable
standard. (EN stands for "European
Norm"). Do not use marine diesel fuel,
heating oils, or non-approved fuel addi-
tives, as this will increase wear andcause damage to the engine and fuel
system. The use of non-approved fuels
and / or fuel additives will result in a limi-
tation of your warranty rights. Diesel fuel of 52 to 54 cetane is used in
your vehicle. If two types of diesel fuel

Biodiesel
Commercially supplied biodiesel blends of no more than 5% biodiesel, commonly
known as "B5 biodiesel" may be used in
your vehicle if it meets EN 14214 or
equivalent specifications. (EN stands for
"European Norm"). The use of biofuels
made from rapeseed methyl ester
(RME), fatty acid methyl ester (FAME),
vegetable oil methyl ester (VME) etc. ormixing diesel with biodiesel will cause
increased wear or damage to the engine
and fuel system. Repair or replacement
of worn or damaged components due to
the use of non approved fuels will not be
covered by the manufactures warranty.A030000AUN-EA
No special run-in period is needed. By
following a few simple precautions for the
first 1,000 km (600 miles) you may add to
the performance, economy and life of
your vehicle.
Do not race the engine.
While driving, keep your engine speed
(rpm, or revolutions per minute)
between 2,000 rpm and 4,000 rpm.
Do not maintain a single speed for long periods of time, either fast or slow.
Varying engine speed is needed to
properly run-in the engine.
Avoid hard stops, except in emergen- cies, to allow the brakes to seat prop-
erly.
Don't let the engine idle longer than 3 minutes at one time.
Don't tow a trailer during the first 2,000 km (1,200 miles) of operation.
CAUTION
Do not let any petrol or water
enter the tank. This would make itnecessary to drain it out and tobleed the lines to avoid jamming
the injection pump and damagingthe engine.
In winter, in order to cut down incidents due to freezing, paraffinoil may be added to the fuel if the
temperature drops to below - 10°C(50°F). Never use more than20% paraffin oil.
CAUTION
Never use any fuel, whether diesel or B5 biodiesel that fails tomeet the latest petroleum indus-
try specification.
Never use any fuel additives or treatments that are not recom-mended or approved by the vehi-cle manufacturer.

C020100AUN-EA Seat belt restraint system
The use of seat belts reduces the risk of
accident injury by avoiding collision with
the interior of the car and by preventing
the occupants from being thrown out of
the car. This makes them the most impor-
tant safety feature available for you and
your passengers. Adequate protection is
afforded only when the belt is worn cor-
rectly. You should always fasten and
adjust your seatbelts before the car is put
in motion and encourage your passen-
gers to do the same.
WARNING - Cargo loading
Make sure the engine is off, the transaxle is in P and the parking
brake is applied whenever loading
or unloading cargo. Failure to take
these steps may allow the vehicle
to move if shift lever is inadvertent-
ly moved to another position.
WARNING - Cargo
Cargo should always be secured to
prevent it from being thrown about
the vehicle in a collision and caus-
ing injury to the vehicle occupants.Special care should be taken ofobjects placed in the rear seats,
since those may hit the front seat
occupants in a frontal collision.
SEAT BELTS
WARNING
For maximum restraint system protection, the seat belts must
always be used whenever the car
is moving.
Seat belts are most effective when seatbacks are in theupright position.
Children age 12 and younger must always be properly
restrained in the rear seat. Never
allow children to ride in the front
passenger seat. If a child over 12
must be seated in the front seat,
he/she must be properly belted
and the seat should be moved as
far back as possible.
Never wear the shoulder belt under your arm or behind your
back. An improperly positionedshoulder belt can cause serious
injuries in a crash. The shoulder
belt should be positioned midway
over your shoulder across your
collarbone.

Driver's and passenger's front air
bag (if equipped)
Your vehicle is equipped with a
Supplemental Restraint (Air Bag) System
and lap/shoulder belts at both the driver
and passenger seating positions. Theindications of the system's presence are
the letters "SRS AIR BAG" embossed on
the air bag pad cover in the steeringwheel and the passenger's side front
panel pad above the glove box. The SRS consists of air bags installed
under the pad covers in the centre of the
steering wheel and the passenger's side
front panel above the glove box.
WARNING
If an air bag deploys, there may be a loud noise followed by a fine
dust released in the vehicle.These conditions are normal and
are not hazardous - the air bags
are packed in this fine powder.
The dust generated during air
bag deployment may cause skin
or eye irritation as well as aggra-
vate asthma for some persons.
Always wash all exposed skin
areas thoroughly with lukewarmwater and a mild soap after an
accident in which the air bags
were deployed.
(Continued)(Continued)
The SRS can function only whenthe ignition key is in the "ON"
position. If the SRS air bag warn-
ing light does not illuminate, or
continuously remains on after
illuminating for about 6 seconds
when the ignition key is turned to
the ON position, or after the
engine is started, comes on while
driving, the SRS is not working
properly. If this occurs, have your
vehicle immediately inspected by
an authorised HYUNDAI dealer.
Before you replace a fuse or dis- connect a battery terminal, turn
the ignition switch to the LOCK
position and remove the ignition
key. Never remove or replace the
air bag related fuse(s) when the
ignition switch is in the ON posi-
tion. Failure to heed this warning
will cause the SRS air bag warn-
ing light to illuminate.

Curtain air bag (if equipped)
Curtain air bags are located along both
sides of the roof rails above the front and
rear doors.
They are designed to help protect the heads of the front seat occupants andthe rear outboard seat occupants in cer-
tain side impact collisions.The curtain air bags are designed to
deploy only during certain side impact
collisions, depending on the crash sever-
ity, angle, speed and impact. The curtain
air bags are not designed to deploy in all
side impact situations, collisions from the
front or rear of the vehicle or in most
rollover situations.
Important safety notes for curtain
airbag systems
Following is a number of safety points
concerning this system which should
always be observed to ensure risk of
injury is reduced in an accident.
WARNING
Before installing child restraints, always refer to "Child Restraint System" to ensure correct instal-
lation and occupant protection ismaximised.
Make sure that the occupant does not have any body parts
(head, arms & legs) protruding
outside the restraining system. If
an inflating airbag was to strike
an infant child on the head, it may
cause serious injury.
(Continued)
(Continued)
Ensure the opening for theCurtain Airbag System remains
unobstructed at all times, so that
the airbags can inflate properly ifneeded.
The built in coat hooks should only be used for light weight
clothing, ensure that pockets are
free of any heavy or sharp
objects. When using coat hooks,
do not hang clothes on coat
hangers.
The space between the occupant and the curtain airbag must never
be occupied by children, passen-
gers or pets. Occupants should
never lean out or have any parts
of their body protruding from the
window whilst the engine is run-ning.
Do not move the sun visor out to cover the side window if there is
an item attached to it such as
garage door remote control,
pens, air fresheners or the like.
These objects may cause injury if
the Curtain Airbag is deployed.

C041100AFD-EA SRS Care
The SRS is virtually maintenance-free
and so there are no parts you can safely
service by yourself. If the SRS air bag
warning light does not illuminate, or con-
tinuously remains on, have your vehicle
immediately inspected by an authorised
HYUNDAI dealer.
Any work on the SRS system, such as
removing, installing, repairing, or any
work on the steering wheel must be per-
formed by an authorised HYUNDAI deal-
er. Improper handling of the SRS system
may result in serious personal injury.
WARNING
Modification to SRS components or wiring, including the addition
of any kind of badges to the pad
covers or modifications to the
body structure, can adversely
affect SRS performance and lead
to possible injury.
For cleaning the air bag pad cov- ers, use only a soft, dry cloth or
one which has been moistened
with plain water. Solvents or
cleaners could adversely affect
the air bag covers and proper
deployment of the system.
No objects should be placed over or near the air bag modules on
the steering wheel, instrument
panel, and the front passenger's
panel above the glove box,
because any such object could
cause harm if the vehicle is in a
crash severe enough to cause
the air bags to inflate.
(Continued)(Continued)
If the air bags inflate, they mustbe replaced by an authorised
HYUNDAI dealer.
Do not tamper with or disconnect SRS wiring, or other components
of the SRS system. Doing so
could result in injury, due to acci-
dental inflation of the air bags or
by rendering the SRS inopera-
tive.
If components of the air bag sys- tem must be discarded, or if the
vehicle must be scrapped, certain
safety precautions must be
observed. An authorised
HYUNDAI dealer knows these
precautions and can give you the
necessary information. Failure to
follow these precautions and pro-cedures could increase the risk
of personal injury.
If your car was flooded and has soaked carpeting or water on
flooring, you shouldn't try to start
the engine; have the car towed to
an authorised HYUNDAI dealer.
