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 is in the
ON position, or continuously remains
on, we recommend that the system
be immediately inspected by an
authorised HYUNDAI dealer.
We recommend any work on the SRS
system, such as removing, installing,
repairing, or any work on the steering
wheel, the front passenger's panel,
front seats and roof rails be performed
by an authorised HYUNDAI dealer.
Improper handling of the SRS system
may result in serious personal injury.
OAE038056
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, and the front passenger'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 system.
We recommend that inflated
air bags be replaced by an
authorised HYUNDAI dealer.

Additional safety precautions
Passengers should not move out of
or change seats whilst the vehicle
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 be ejected
from the vehicle.
Do not use any accessories on seat
belts.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.
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 front
seats.Placing items under the front
seats could interfere with the opera-
tion of the supplemental restraint sys-
tem sensing components and wiring
harnesses.
Do not cause impact to the doors.
Impact to the doors when the ignition
switch is in the ON position may cause
the air bags to inflate. (Continued)If components of the air bag
system must be discarded, or if
the vehicle must be scrapped,
certain safety precautions must
be observed. Consult an autho-
rised HYUNDAI dealer for the
necess
ary information. Failure
to follow these precautions
could increase the risk of per-
sonal injury.

Driving your vehicle
Check battery and cables
Winter temperatures affect battery
performance.Inspect the battery
and cables, as specified in the
chapter 7.The battery charging level
can be checked by an authorised
HYUNDAI dealer or in a service sta-
tion.
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
authorised HYUNDAI dealer.Check spark plugs and ignition
system
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.Use approved window washer
anti-freeze solution in system
To prevent the window washer from
being frozen, add authorised window
washer anti-freeze solution, as spec-
ified on the window washer contain-
er. Window washer anti-freeze solu-
tion is available from an authorised
HYUNDAI dealer, and most vehicle
accessory outlets. Do not use engine
coolant or other types of anti-freeze
solution, to prevent any damage to
the vehicle paint.

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.
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 indi-
cates an electrical problem. Avoid
using the system involved and immedi-
ately consult an authorised HYUNDAI
dealer.Information
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and multi fuse for higher
amperage ratings.
Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage the sys-
tem.

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

Consult an authorised HYUNDAI
dealer to replace most vehicle light
bulbs. It is difficult to replace vehicle
light bulbs because other parts of the
vehicle must be removed before you
can get to the bulb. This is especially
true for removing the headlamp
assembly to get to the bulb(s).
Removing/installing the headlamp
assembly can result in damage to
the vehicle.Be sure to replace the burned-out
bulb with one of the same wattage
rating. Otherwise, it may cause
damage to the fuse or electric
wiring system.
Information
The headlamp and tail lamp lenses
could appear frosty if the vehicle is
washed after driving or the vehicle is
driven at night in wet weather. This
condition is caused by temperature dif-
ference between the lamp inside and
outside and, it does not indicate a prob-
lem with your vehicle. When moisture
condenses in the lamp, it will be
removed after driving with the head-
lamp on. The removable level may dif-
fer depending on lamp size, lamp posi-
tion and environmental condition.
However, if moisture is not removed,
we recommend that your vehicle is
inspected by an authorised HYUNDAI
dealer.
Information
• A normally functioning lamp may
flicker momentarily to stabilize the
vehicle’s electrical control system.
However, if the lamp goes out after
flickering momentarily, or contin-
ues to flicker, we recommend the
system be checked by an authorised
HYUNDAI dealer.
• The position lamp may not turn on
when the position lamp switch is
turned on, but the position lamp and
headlamp switch may turn on when
the headlamp switch is turned on.
This may be caused by network fail-
ure or vehicle electrical control sys-
tem malfunction. If this occurs, we
recommend the system be checked
by an authorised HYUNDAI dealer.

ment of the vehicle and burning
your fingers or receiving an elec-
tric shock.
