WARNING
Radiator hose
Be very careful not to touch the
radiator hose when checking or adding
the engine oil as it may be hot enough
to burn you.
CAUTION
• Do not overfill the engine oil. It may
damage the engine.
• Do not spill engine oil, when adding
or changing engine oil. If you drop
the engine oil on the engine room,
wipe it off immediately.
• When you wipe the oil level gauge,
you should wipe it with a clean cloth.
When mixed with debris, it can cause
engine damage.
• Oil consumption may increase while
you break in a new vehicle and it will
be stabilized after driving 6,000 km.
• The engine oil consumption can be
affected by driving habits, climate
conditions, traffic conditions,
oil quality, etc. Therefore, it is
recommended that you inspect the
engine oil level regularly and refill it if
necessary.
• The engine oil change interval is
set for the purpose of preventing
oil deterioration, and is not related
the amount of oil consumption; so,
check and refill the amount of the oil
regularly.

FigureRequired action
Range (A)Recommend to contact
an authorized HYUNDAI
dealer.
Range (B)Do not refill engine oil.
Range (C)You may add engine oil
as long as the oil level
does not go above the C
range.
Range (D)You must add oil and
make sure that the oil
level is in the C Range.
1. Be sure the vehicle is on level ground.
2. Start the engine and allow it to reach
normal operating temperature.
3. Turn the engine off and wait for a few
minutes (about 5 minutes) for the oil
to return to the oil pan.
4. Pull the dipstick out, wipe it clean, and
re-insert it fully.
5. Pull the dipstick out again and check
the level.
6. The level should be in the C range. If
the level is in the D range, add enough
engine oil to bring the level up to the
C range.

If it is near or at L, add enough oil to
bring the level to F. Do not overfill.
Use only the specified engine oil.
• If exceeding the maintenance
schedule for replacement of engine
oil, the engine oil performance
may deteriorate and the engine
condition may be affected. Therefore,
the replacement cycle should be
observed.
• If not using the recommended oil,
replace it according to the severe
usage maintenance conditions.
(Refer to “Recommended lubricants
and capacities” in chapter 2.)

Changing the engine oil and
filter
We recommend that the engine oil
and filter be replaced by an authorized
HYUNDAI dealer.
WARNING
Used engine oil may cause skin
irritation or cancer if left in contact

WARNING
Brake/clutch fluid
When changing and adding brake/
clutch fluid, handle it carefully. Do not
let it come in contact with your eyes.
If brake/clutch fluid come in contact
with your eyes, immediately flush them
with a large quantity of fresh tap water.
Have your eyes examined by a doctor
as soon as possible.
NOTICE
Do not allow brake/clutch fluid to
contact the vehicle’s body paint, as
paint damage will result.
Brake/clutch fluid, which has been
exposed to open air for an extended
time should never be used as its quality
cannot be guaranteed. It should be
properly disposed. Don’t put in the
wrong kind of fluid. A few drops of
mineral-based oil, such as engine oil, in
your brake/clutch system can damage
brake/clutch system parts.

Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged in a
short time (because, for example, the
headlights or interior lights were left
on while the vehicle was not in use),
recharge it by slow charging (trickle)
for 10 hours.
• If the battery gradually discharges
because of high electric load while the
vehicle is being used, recharge it at
20-30A for two hours.
WARNING
Recharging battery
When recharging the battery, observe
the following precautions:
• The battery must be removed from
the vehicle and placed in an area with
good ventilation.
• Do not allow cigarettes, sparks, or
flame near the battery.
• Watch the battery during charging,
and stop or reduce the charging
rate if the battery cells begin
gassing (boiling) violently or if the
temperature of the electrolyte of any
cell exceeds 49°C (120°F).
• Wear eye protection when checking
the battery during charging.
• Disconnect the battery charger in the
following order.
1. Turn off the battery charger main
switch.
2. Unhook the negative clamp from the
negative battery terminal.
3. Unhook the positive clamp from the
positive battery terminal.

A vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 2 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 an
authorized HYUNDAI dealer.
i Information
Three kinds of fuses are used: blade type
for lower amperage rating, cartridge
type, and multi fuse for higher amperage
ratings.
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 aluminum
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.
