Changing the engine coolant
We recommend that coolant be changed
by an authorised HYUNDAI according to
the Maintenance Schedule.
NOTICE
Put a thick cloth or fabric around the
radiator cap before refilling the coolant
in order to prevent the coolant from
overflowing into engine parts such as
alternator.
WARNING
Do not use engine coolant or antifreeze
in the washer fluid reservoir.
Engine coolant can severely obscure
visibility when sprayed on the
windscreen and may cause loss of
vehicle control resulting in an accident.
Engine coolant may also cause damage
to paint and body trim.

Do not allow brake/clutch fluid to come
in contact with your eyes. If brake/
clutch fluid comes in contact with
your eyes, flush your eyes with clean
water for at least 15 minutes and get
immediate medical attention.

Checking the washer fluid level
OBC3090017
Check the fluid level in the washer fluid
reservoir and add fluid if necessary.
Plain water may be used if washer fluid
is not available.
However, use washer solvent with
antifreeze characteristics in cold
climates to prevent freezing.
WARNING
To prevent serious injury or death, take
the following safety precautions when
using washer fluid:

Checking the parking brake
OBC3060005
Check the stroke of the parking brake by
counting the number of “clicks’’ heard
whilst fully applying it from the released
position.
Also, the parking brake alone should
securely hold the vehicle on a fairly
steep grade. If the stroke is more or
less than specified, we recommend that
the system be inspected by a HYUNDAI
authorised repairer.
Stroke : 5~7 “clicks’’ at a force of 20 kg
(44 lbs, 196 N).

WARNING
To prevent SERIOUS INJURY or DEATH
to you or bystanders, always follow
these precautions when working near
or handling the battery:
Always read and follow
instructions carefully when
handling a battery.
Wear eye protection designed
to protect the eyes from acid
splashes.
Keep all flames, sparks, or
smoking materials away from
the battery.
Hydrogen is always present in
battery cells, is highly
combustible, and may explode
if ignited.
% D W W H U L H V F R Q W D L Q V X O I X U L F D F L G
which is highly corrosive. Do
not allow acid to contact your
eyes, skin or clothing.
If acid gets into your eyes, flush your
eyes with clean water for at least 15
minutes and get immediate medical
attention. If acid gets on your skin,
thoroughly wash the area. If you
feel pain or a burning sensation, get
medical attention immediately.
[ When lifting a plastic-cased battery,
excessive pressure on the case may
cause battery acid to leak. Lift with a
battery carrier or with your hands on
opposite corners.
[ Do not attempt to jump start your
vehicle if your battery is frozen.
[ NEVER attempt to recharge the
battery when the vehicle’s battery
cables are connected to the battery.
[ The electrical ignition system works
with high voltage. NEVER touch these
components with the engine running
or when the Engine Start/Stop button
is in the ON position.
[ Do not allow the (+) and (-) jumper
cables to touch. It may cause sparks.
[ The battery may rupture or explode
when you jump start with a low or
frozen battery.
[ Leaked battery electrolyte due to
repeated driving on sharp curves
(e.g. on circuits) may cause safety
problem. Avoid repeated driving on
sharp curves.
NOTICE
If you connect unauthorised electronic
devices to the battery, the battery may
be discharged. Never use unauthorised
devices.

„ Blade type

„ Multi fuse
NormalBlown
NormalBlown
A vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 2 (or 3) fuse panels, one
located in the driver’s side panel bolster,
the other in the engine compartment.
If any of your vehicle’s lights,
accessories, 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 rating.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and we
recommend that all inspect a HYUNDAI
authorised repairer.

WARNING
NEVER replace a fuse with anything 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 aluminium
foil instead of the proper fuse -
even as a temporary repair. It may
cause extensive wiring damage and
possibly a fire.
NOTICE
Do not use a screwdriver or any other
metal object to remove fuses because
it may cause a short circuit and damage
the system.

1. Turn the vehicle off.
2. Turn all other switches OFF.
3. Open the fuse panel cover.
4. Refer to the label on the inside of
the fuse panel cover to locate the
suspected broken fuse location.
OBC3N091018AU
5. Pull the suspected fuse straight out.
Use the removal tool provided in the
engine compartment fuses panel.
6. Check the removed fuse; replace it if
it is blown. Spare fuses are provided in
the instrument panel fuse panels (or in
the engine compartment fuse panel).
7. Push in a new fuse of the same rating,
and make sure it fits tightly in the
clips.If it fits loosely, we recommend
that you consult with a HYUNDAI
authorised repairer.
In an emergency, if you do not have a
spare fuse, use a fuse of the same rating
from a circuit such as the cigarette
lighter fuse.
If the headlights or other electrical
components do not work and the fuses
are undamaged, check the fuse panel
in the engine compartment. If a fuse
is blown, it must be replaced with the
same rating.
