Safety system of your vehicle
Air bags may not inflate if the vehicle collides with objects such as utility
poles or trees, where the point of
impact is concentrated and the colli-
sion energy is absorbed by the vehi-
cle structure.
SRS Care
The SRS is virtually maintenance-
free and there are no parts you can
safely service by yourself. If the SRS
air bag warning light does not illumi-
nate when the ignition switch or the
Engine Start/Stop button is in the ON
position, or continuously remains on,
have your vehicle immediately
inspected by an authorized
HYUNDAI dealer.
Any work on the SRS system, such
as removing, installing, repairing, or
any work on the steering wheel, thefront passenger's panel, front seats
and roof rails must be performed by
an authorized HYUNDAI dealer.Improper handling of the SRS sys-
tem may result in serious personal
injury.To reduce the risk of serious
injury or death, take the follow-ing precautions:
Do not attempt to modify or disconnect the SRS compo-
nents or wiring, including the
addition of any kind of badges
to the pad covers or modifica-
tions to the body structure.
Do not place objects over or
near the air bag modules on
the steering wheel, instrument
panel, or the front passen-
ger’s panel above the glove
box.
Clean the air bag pad covers
with a soft cloth moistened
with plain water. Solvents or
cleaners could adversely
affect the air bag covers and
proper deployment of the sys-tem.
Always have inflated air bags
replaced by an authorized
HYUNDAI dealer.

Additional Safety Precautions
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 vehi-
cle, against other occupants, or be
ejected from the vehicle.
Do not use any accessories on seat belts. Devices claiming to
improve occupant comfort or reposi-tion the seat belt can reduce the pro-
tection provided by the seat belt and
increase the chance of serious injury
in a crash
Do not modify the front seats. Modification of the front seats could
interfere with the operation of the
supplemental restraint system sens-
ing components or side air bags.
Do not place items under the front seats. Placing items under the front
seats could interfere with the opera-
tion of the supplemental restraintsystem sensing components and
wiring harnesses. Do not cause impact to the doors.Impact to the doors when the ignition
switch or the Engine Start/Stop but-
ton is in the ON position may cause
the air bags to inflate. Modifications to accommodate dis- abilities.
If you require modification to your
vehicle to accommodate a disability,
contact the HYUNDAI Auto Canadaat 1-888-216-2626.
Adding equipment to or modify-
ing your air bag equipped vehi- cle
If you modify your vehicle by chang-
ing your vehicle's frame, bumper sys-tem, front end or side sheet metal or
ride height, this may affect the oper-
ation of your vehicle's air bag sys-tem.
(Continued)
If components of the air bag
system must be discarded, or
if the vehicle must be
scrapped, certain safety pre-
cautions must be observed.
Consult an authorized
HYUNDAI dealer for the nec-
essary information. Failure to
follow these precautionscould increase the risk of per-
sonal injury.

Winter Precautions
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 ofcoolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolantin accordance with the maintenance
schedule in section 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.Check battery and cables
The winter temperature increases
the battery consumption.
Inspect
the battery and cables, as speci-
fied in the chapter 7. The battery
charging level can be checked by an
authorized HYUNDAI dealer or in a
service station.
Change to "winter weight" oil if
necessary
In some regions during winter, it is recommended to use the "winter
weight" oil with lower viscosity. For
further information, refer to the chap-
ter 8. When you are not sure about a
type of winter weight oil, consult an
authorized HYUNDAI dealer. Check spark plugs and ignitionsystem
Inspect the spark plugs, as speci-
fied in the chapter 7.
If necessary,
replace them. Also check all ignition
wirings and components for any
cracks, wear-out, and damage.
To prevent locks from freezing
To prevent the locks from being
frozen, spray approved de-icing fluid
or glycerin into key holes. When a
lock opening is already covered with
ice, spray approved de-icing fluid
over the ice to remove it. When an
internal part of a lock freezes, try to
thaw it with a heated key. Carefully
use the heated key to avoid an injury.

Maintenance
FFUU SSEE SS
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver’s side panel
bolster, the other in the engine com-
partment 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 or broken.
If the electrical system does not
work, first check the driver’s side
fuse panel. Before replacing a blown
fuse, turn the engine and all switches
off, and then disconnect the negative
battery cable. Always replace a
blown fuse with one of the same rat-ing.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized
HYUNDAI dealer. Information
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and fusible link for higher
amperage ratings.i

OLF074075 NEVER replace a fuse with any-
thing but another fuse of thesame rating.
A higher capacity fuse could
cause damage and possibly
cause a fire.
Do not install a wire or alu-
minum foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
possibly a fire.
