Safety features of your vehicle
The purpose of the SRS is to provide the
vehicle's driver and/or the front passen-ger with additional protection than that
offered by the seat belt system alone incase of a frontal impact of sufficient
severity.
OYF039031R
Passenger’s front air bag
WARNING
Always use seat belts and child
restraints – every trip, every time,
everyone! Air bags inflate with con-
siderable force and in the blink of
an eye. Seat belts help keep occu-
pants in proper position to obtain
maximum benefit from the air bag.
Even with air bags, improperly belt-ed and unbelted occupants can be
severely injured when the air bag
inflates. Always follow the precau-
tions about seat belts, air bags and
occupant safety contained in this
manual.
To reduce the chance of serious or fatal injuries and receive the maxi-
mum safety benefit from yourrestraint 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.
Front and side air bags can injure occupants improperly positioned
in the front seats.
(Continued)(Continued)
Move your seat as far back aspractical from the front air bags,
whilst still maintaining control of
the vehicle.
You and your passengers should never sit or lean unnecessarily
close to the air bags. Improperly
positioned drivers and passen-
gers can be severely injured by
inflating air bags.
Never lean against the door or centre console – always sit in an upright position.
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 deploy.
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 inopera-
tive.

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
when you turn the ignition ON, or if it 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, the frontpassenger's panel, front seats and roof
rails must be performed by an authorised
HYUNDAI dealer. 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 must be 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 the
flooring, you shouldn't try to start
the engine; have the car towed to
an authorised HYUNDAI dealer.

Safety features of your vehicle
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 whilst the vehicle is
moving. A passenger who is not wear-
ing a seat belt during a crash or emer-
gency stop can be thrown against the
inside of the vehicle, against other
occupants, or out of the vehicle.
Each seat belt is designed torestrain one occupant. If more than
one person uses the same seat belt,
they could be seriously injured or killedin a collision.
Do not use any accessories on seatbelts. Devices claiming to improve
occupant comfort or reposition 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 hardor 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 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 sup-
plemental restraint system sensing
components or side air bags.
Do not place items under the frontseats. Placing items under the front
seats could interfere with the operation
of the supplemental restraint system
sensing components and wiring har-
nesses.
Never hold an infant or child on yourlap. 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 therear seat. Adding equipment to or modifying
your air bag-equipped vehicle
If you modify your vehicle by changing
your vehicle's frame, bumper system,
front end or side sheet metal or ride
height, this may affect the operation of
your vehicle's air bag system.
WARNING
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 vehicle
resulting in serious injury ordeath.
Always sit upright with the seat- back in an upright position, cen-tred on the seat cushion with
your seat belt on, legs comfort-
ably extended and your feet on
the floor.

KEYS
WARNING
- Ignition key
Leaving children unattended in a
vehicle with the ignition key is dan-
gerous even if the key is not in the
ignition switch. Children copy
adults and they could place the key
in the ignition switch. The ignition
key would enable children to oper-
ate power windows or other con-
trols, or even make the vehicle
move, which could result in serious
bodily injury or even death. Never
leave the keys in your vehicle with
unsupervised children.
WARNING
Use only HYUNDAI original parts
for the ignition key in your vehicle.
If an aftermarket key is used, the
ignition switch may not return to
ON after START. If this happens,
the starter will continue to operate
causing damage to the starter
motor and possible fire due to
excessive current in the wiring.

Use high quality ethylene glycol coolant
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 cooling system, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with themaintenance schedule in section 7.
Before winter, have your coolant tested toassure 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 bat-
tery and cables as described in section
7. The level of charge in your battery can
be checked by an authorised 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 section 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorised HYUNDAI dealer.
Check spark plugs and ignition system
Inspect your spark plugs as described in
section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
WARNING
- Tyre chains
The use of chains may adversely affect vehicle handling.
Do not exceed 30 km/h (20 mph) or the chain manufacturer’s rec-
ommended speed limit, whichev-
er is lower.
Drive carefully and avoid bumps, holes, sharp turns, and other
road hazards, which may cause
the vehicle to bounce.
Avoid sharp turns or locked- wheel braking.
CAUTION
Chains that are the wrong size or
improperly installed can damage
your vehicle's brake lines, sus-pension, body and wheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.

Driving your vehicle
Turn signals when towing a trailer
When you tow a trailer, your vehicle has
to have a different turn signal flasher and
extra wiring. The green arrows on your
instrument panel will flash whenever you
signal a turn or lane change. Properly
connected, the trailer lights will also flash
to alert other drivers you’re about to turn,
change lanes, or stop.
When towing a trailer, the green arrows
on your instrument panel will flash for
turns even if the bulbs on the trailer are
burned out. Thus, you may think drivers
behind you are seeing your signals
when, in fact, they are not. It’s important
to check occasionally to be sure the trail-
er bulbs are still working. You must also
check the lights every time you discon-
nect and then reconnect the wires.
Do not connect a trailer lighting system
directly to your vehicle’s lighting system.
Use only an approved trailer wiring har-
ness.
An authorised HYUNDAI dealer can
assist you in installing the wiring harness.
Driving on grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes so much
that they would get hot and no longer
operate efficiently.
On a long uphill grade, shift down and
reduce your speed to around 70 km/h (45mph) to reduce the possibility of engine
and transaxle overheating.
If your trailer weighs more than the max-
imum trailer weight without trailer brakes
and you have an automatic transaxle,
you should drive in D (Drive) when tow-
ing a trailer.
Operating your vehicle in D (Drive) when
towing a trailer will minimise heat build up
and extend the life of your transaxle.WARNING
Failure to use an approved trailer wiring harness could result in dam-
age to the vehicle electrical system
and/or personal injury.

FUSES
A vehicle’s electrical system is protected
from electrical overload damage by
fuses. This vehicle has 2 fuse panels, one locat-
ed in the driver’s side panel bolster,
another is in the engine compartment.
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 bemelted.
If the electrical system does not work,
first check the driver’s side fuse panel.
Always replace a blown fuse with one of
the same rating.
If the replacement fuse blows, this indi-
cates an electrical problem. Avoid using
the system involved and immediately
consult an authorised HYUNDAI dealer.
Three kinds of fuses are used: blade type
for lower amperage rating, cartridge type,
and multi fuse for higher amperage rat- ings.
WARNING - Fuse replace-
ment
Never replace a fuse with any- thing but another fuse of the same rating.
A higher capacity fuse could cause damage and possibly a
fire.
Never install a wire or aluminum foil instead of the proper fuse -
even as a temporary repair. It may
cause extensive wiring damage
and a possible fire.
CAUTION
Do not use a screwdriver or any
other metal object to remove fuses because it may cause a short circuit
and damage the system.

LIGHT BULBS
Use only the bulbs of the specifiedwattage.
All bulbs are available from yourHYUNDAI dealers Parts Department.
✽✽ NOTICE
After heavy, driving rain or washing,
headlight and taillight lenses could
appear frosty. This condition is caused by
the temperature difference between the
lamp inside and outside. This is similar
to the condensation on your windows
inside your vehicle during the rain and
doesn’t indicate a problem with your
vehicle. If the water leaks into the lamp
bulb circuitry, have the vehicle checked
by an authorised HYUNDAI dealer.
