How does the air bag system
operate
• Air bags are activated (able to
inflate if necessary) only when the
ignition switch is placed to the ON
or START position.
• Air bags inflate instantly in the event of serious frontal or side col
lision in order to help protect the
occupants from serious physical
injury.
• There is no single speed at which the air bags will inflate.
Generally, air bags are designed to
inflate based upon the severity of a
collision and its direction. These
two factors determine whether the
sensors produce an electronic
deployment\f inflation signal.
• Air bag deployment depends on a number of factors including vehicle
speed, angles of impact and the
density and stiffness of the vehi
cles or objects which your vehicle
hits in the collision. The determin
ing, factors are not limited to those
mentioned above. • The front air bags will completely
inflate and deflate in an instant.
It is virtually impossible for you to
see the air bags inflate during an
accident.
It is much more likely that you will
simply see the deflated air bags
hanging out of their storage com
partments after the collision.
• In order to help provide protection in a severe collision, the air bags
must inflate rapidly. The speed of
air bag inflation is a consequence
of extremely short time in which a
collision occurs and the need to
get the air bag between the occu
pant and the vehicle structures
before the occupant impacts those
structures. This speed of inflation
reduces the risk of serious or life
threatening injuries in a severe col
lision and is thus a necessary part
of air bag design.
However, air bag inflation can also
cause injuries which can include
facial abrasions, bruises and bro
ken bones because the inflation
speed also causes the air bags to
expand with a great deal of force.•Even in vehicles with air bags,
you and your passengers must
always wear the safety belts pro
vided in order to minimize the risk
and severity of injury in the event
of a collision or rollover.
•SRS and pretensioners contain
explosive chemicals.
If scraping a vehicle without
removing SRS and pretensioners
from a vehicle, it may cause fire.
Before scraping a vehicle, we
recommend that you contact an
authorized HYUNDAI dealer.
•Keep the SRS parts and wirings
away from water or any liquid. If
the SRS components are inoper
ative due to exposure to water or
liquids, it may cause fire or severe
injury.

(Continued)
•Front and side impact air bags
can injure occupants improperly
positioned in the front seats.
•Move your seat as far back as
practical from the front air bags,
while still maintaining control of
the vehicle.
•You and your passengers
should never sit or lean unnec
essarily close to the air bags.
Improperly positioned drivers
and passengers can be severe
ly injured by inflating air bags.
•Never lean against the door or
center console – always sit in an
upright position.
(Continued)
Always use seat belts and child
restraints – every trip, every time,
everyone! Air bags inflate with
considerable force and in the blink
of an eye. Seat belts help keep
occupants in proper position to
obtain maximum benefit from the
air bag. Even with air bags,
improperly and unbelted occu
pants can be severely injured
when the air bag inflates. Always
follow the precautions about seat
belts, air bags and occupant safe
t

y contained in this manual.
To reduce the chance of serious
or fatal injuries and receive the
maximum safety benefit from your
restraint system:
•Never place a child in any child
or booster seat in the front seat.
•ABC – Always Buckle Children in
the back seat. It is the safest
place for children of any age to
ride. (Continued)
WARNING (Continued)
•No objects (such as crash pad
cover, cellular phone holder, cup
holder, perfume or stickers)
should be placed over or near
the air bag modules on the
steering wheel, instrument
panel, windshield glass, and the
front passenger's panel above
the glove box. Such objects
could cause harm if the vehicle
is in a crash severe enough to
cause the air bags to deploy.
•Do not attach any objects on the
front windshield and inside mir
r
or.
•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 deployment of the air
bags or by rendering the SRS
inoperative.
•If the SRS air bag warning light
remains illuminated while the
vehicle is being driven, we rec
ommend that the system be
inspected by an authorized
HYUNDAI dealer.

•Modification to SRS compo
nents or wiring, including the
addition of any kind of badges to
the pad covers or modifications
to the body structure, can
adversely affect SRS perform
ance and lead to possible injury.
•For cleaning the air bag pad
covers, use only a soft, dry cloth
or one which has been mois
tened with plain water. Solvents
or cleaners could adversely
affect the air bag covers and
proper deployment of the sys
t

em.
•No objects should be placed
over or near the air bag modules
on the steering wheel, instru
ment panel, and the front pas
senger'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)
WARNING •If the air bags inflate, we recom
mend that the system be replaced
by an authorized HYUNDAI deal
er.
•Do not tamper with or discon
nect SRS wiring, or other com
ponents of the SRS system.
Doing so could result in injury,
due to accidental inflation of the
air bags or by rendering the
SRS inoperative.
•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 authorized
HYUNDAI dealer kn

ows these
precautions and can give you
the necessary information.
Failure to follow these precau
tions and procedures could
increase the risk of personal
injury.

•If your car was flooded and has
soaked carpeting or water on
the flooring, you shouldn't try to
start the engine; we recommend
that you contact an authorized
HYUNDAI dealer.


"&t%'s%st&'!"'%!'&&
Additional safety precautions
• Never let passengers ride in the
cargo area or on top of a folded
down back seat.
All occupants
should sit upright, fully back in their
seats with their seat belts on and
their feet on the floor.
• Passengers should not move out
of or change seats while the vehi
cle is moving.
A passenger who is
not wearing a seat belt during a
crash or emergency stop can be
thrown against the inside of the
vehicle, against other occupants,
or out of the vehicle.
• Each seat belt is designed to
restrain one occupant.
If more than
one person uses the same seat
belt, they could be seriously injured
or killed in a collision.
• Do not use any accessories on
seat belts.
Devices claiming to
improve occupant comfort or repo
sition the seat belt can reduce the
protection provided by the seat belt
and increase the chance of serious
injury in a crash. •
Passengers should not place hard
or sharp objects between them
selves and the air bags.
Carrying
hard or sharp objects on your lap
or in your mouth can result in
injuries if an air bag inflates.
• Keep occupants away from the air
bag
covers.
All
occupants should
sit upright, fully back in their seats
with their seat belts on and their
feet on the floor. If occupants are
too close to the air bag covers,
they could be injured if the air bags
inflate.
• Do not attach or place objects on
or near the air bag covers.
Any
object attached to or placed on the
front or side impact air bag covers
could interfere with the proper
operation of the air bags.
• Do not modify the front seats.
Modification of the front seats
could interfere with the operation of
the supplemental restraint system
sensing components or side impact air bags. •
Do not place items under the front
seats.
Placing items under the
front seats could interfere with the
operation of the supplemental
restraint system sensing compo
nents and wiring harnesses.
• Never hold an infant or child on your
lap.
The infant or child could be seri
ously injured or killed in the event of
a crash. All infants and children
should be properly restrained in
appropriate child safety seats or
seat belts in the rear seat.
•Sitting improperly or out of posi
tion can cause occupants to be
shifted too close to a deploying
air bag, strike the interior struc
ture or be thrown from the vehi
cle resulting in serious injury or
death.
•Always sit upright with the seat
back in an upright position, cen
tered on the seat cushion with
your seat belt on, legs comfort
ably extended and your feet on
the floor.
WARNING

When using tire chains:
• Wrong size chains or improperlyinstalled chains can damage your
vehicle's brake lines\b suspension\b
body and wheels.
• Use SAE “S” class or wire chains.
• If you hear noise caused by chains contacting the body\b retighten the
chain to prevent contact with the
vehicle body.
• To prevent body damage\b retighten the chains after driving \f.5~1.\f km
(\f.3~\f.6 miles).
• Do not use tire chains on vehic
les
equipped with aluminum wheels. If
unavoidable\b use a wire type
chain.
• Use wire chains less than 15 mm (\f.59 in) wide to prevent damage
to the chain’s connection.
Winter precautions
Use high quality ethylene glycolcoolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool
ing system\b lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 7. Before winter\b
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 7. The level of charge in
your battery can be checked by an
authorized HYUNDAI dealer or a
service station.
Change to "winter weight" oil if necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 8 for recommendations. If
you aren't sure what weight oil you
should use\b we recommend that you
consult with an authorized HYUNDAI
dealer.
Check spark plugs and ignition system
Inspect your spark plugs as
described in chapter 7 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked\b worn or
damaged in any way.

Diesel Engine
Never work on injection system
with engine running or within 30
seconds after shutting of f engine.
High-pressure pump, rail, injectors
and high-pressure pipes are sub-
ject to high pressure eve n after
the engine stopped. The fuel jet
produced by fuel leaks may cause
serious injury, if it touches the
body. People using pacemakers
should not move more than 30cm
closer to the ECU or wiring har-
ness wi thin the engine room while
engine is running, since the high
currents in the electronic engine
control s ystem produce consider-
able magnetic fields.
WARNING

• When you remove the interior trim cover with a flat head (-) driver, be
careful not to dama ge the cover.
• Be careful when you replace and clean bulbs to avoid burns or elec-
trical shock.
Engine compartment precautions
(Diesel engine)• The injector operates at high volt-
age (maximum 200v). Therefore,
the following accidents may occur.
- Direct contact with the injector orinjector wiring may cause electric
shock or damage your muscle or
nerve system.
- The electromagnetic wave from the operating injector may cause
the artificial heart pacemaker to
malfunction.
• Follow the safety tips provided below, when you are checking the
engine room while the engine is
running.
- Do not touch the injector, injectorwirings, and the engine computer
while the engine is running.
- Do not remove the injector con- nector while the engine is run-
ning.
- People using pacemakers must not go near the engine while the
engine is starting or running.

changed at the intervals specified in
the maintenance schedule. If the car
is being driven in severe conditions,
more frequent oil and filter changes
are required.Drive beltsInspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.When you are inspecting the belt,
place the ignition switch in the
LOCK/OFF or ACC position.
Fuel filterA clogged filter can limit the speed at
which the vehicle may be driven,
damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently.
After installing a new filter, run the
engine for several minutes, and
check for leaks at the connections.
We recommend that the fuel filter be
replaced by an authorized HYUNDAI
dealer.
Fuel lines, fuel hoses and con-
nectionsCheck the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend that the fuel
lines, fuel hoses and connections be
replaced by an authorized HYUNDAI
dealer.

A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 fuse panels, one
located in the driver’s side panel bol-
ster, the other in the engine compart-
ment near the battery.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside the
fuse will be melted.
If the electrical system does not
work, first check the driver’s side
fuse panel.
Before replacing a blown fuse, dis-
connect the negative battery cable.
Always replace a blown fuse with
one of the same rating.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized
HYUNDAI dealer.Three kinds of fuses are used: blade type for lower amperage rating, slowblow type and multi fuse for higheramperage ratings.
Do not use a screwdriver or any
other metal object to remove fuses
because it may cause a short circuit
and damage the system.
