Do not use a solution that contains more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of the
solution.
For mixing percentage, refer to the
following table:
Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of
- 31°F and higher.

Checking the Brake/Clutch
Fluid Level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap
and adding brake/clutch fluid, clean
the area around the reservoir cap
thoroughly to prevent brake/clutch
fluid contamination. If the level is low, add the specified
brake/clutch fluid to the MAX level.
The level will fall with accumulated
mileage. This is a normal condition
associated with the wear of the
brake/clutch linings. If the fluid level
is excessively low, have the brake/
clutch system checked by an author-
ized HYUNDAI dealer.
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 dis-
posed of properly.
Do not use the wrong kind of brake/clutch fluid. A few drops
of mineral based oil, such as
engine oil, in your brake/clutch
system can damage brake/
clutch system parts.
Information
Use only the specified brake/clutch
fluid (refer to "Recommended
Lubricants and Capacities" in chap-
ter 8).

Maintenance
If the brake system requires fre-
quent additions of fluid this
could indicate a leak in the
brake system. Have the vehicle
inspected by an authorized
HYUNDAI dealer.
WARNING
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 imme-
diate medical attention.

Checking the Washer Fluid
Level
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary. Plain water may be used if
washer fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.
Checking the Parking Brake
Check the stroke of the parking
brake by counting the number of
"clicks" heard while 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, have the parking
brake adjusted by an authorized
HYUNDAI dealer.
Stroke : 6 clicks at a force of 44
lbs (20 kg, 196 N)
To prevent serious injury or
death, take the following safety
precautions when using washer
fluid:

Do not use engine coolant or
antifreeze in the washer fluid
reservoir.
Engine coolant can severely
obscure visibility when
sprayed on the windshield
and may cause loss of vehicle
control resulting in an acci-
dent or damage to paint and
body trim.
Do not allow sparks or flame
to contact the washer fluid or
the washer fluid reservoir.
Washer fluid may contain
alcohol and can be flamma-
ble.
Do not drink washer fluid and
avoid contact with skin.
Washer fluid is harmful to
humans and animals.
Keep washer fluid away from
children and animals.

4. Insert the air cleaner cover in the hinge and engage the clamp after
closing the cover.
5. Check that the cover is firmly installed.
Information
If the vehicle is operated in extremely
dusty or sandy areas, replace the ele-
ment more often than the usual rec-
ommended intervals (refer to
"Maintenance Under Severe Usage
Conditions" in this chapter).
Do not drive with the air cleanerfilter removed. This will result in
excessive engine wear.
When removing the air cleaner filter, be careful that dust or dirt
does not enter the air intake, or
damage may result.
Use HYUNDAI genuine parts, use of non-genuine parts could
damage the air flow sensor.

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
Four kinds of fuses are used : blade
type for lower amperage rating, car-
tridge type/Multi fuse/Battery fuse
terminal 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.
NOTICE
i
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-
minum foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
possibly a fire.

Maintenance
Instrument Panel Fuse
Replacement
1. Turn the engine off.
2. Turn all other switches OFF.
3. Open the fuse panel cover.
4. Refer to the label on the inside ofthe fuse panel cover to locate the
suspected fuse location. 5. Pull the suspected fuse straight
out. Use the removal tool provided
in the engine compartment fuse
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 com-
partment 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, consult
an authorized HYUNDAI dealer. In an emergency, if you do not have
a spare fuse, use a fuse of the same
rating from a circuit you may not
need for operating the vehicle.
If the headlamps or other electrical
components do not work and the
fuses are OK, check the fuse panel
in the engine compartment. If a fuse
is blown, it must be replaced with the
same rating.

Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in
the canister are drawn into the surge
tank through the purge control sole-
noid valve.
Purge Control Solenoid Valve(PCSV)
The purge control solenoid valve is
controlled by the Engine Control
Module (ECM); when the engine
coolant temperature is low during
idling, the PCSV closes so that evap-
orated fuel is not taken into the
engine. After the engine warms-up
during ordinary driving, the PCSV
opens to introduce evaporated fuel to
the engine.
3. Exhaust Emission Control System
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
while maintaining good vehicle per-
formance.
When the engine starts or fails to
start, excessive attempts to restart
the engine may cause damage to the
emission system.
Engine exhaust (carbon monox-
ide) precautions
Carbon monoxide can be present
with other exhaust fumes. If you
smell exhaust fumes of any kind in
your vehicle, drive with all the win-
dows fully open. Have your vehicle
checked and repaired immediately.
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
on this page to avoid CO poi-
soning.

Specifications, Consumer information and Reporting safety defects
Recommended SAE viscosity
number Engine oil viscosity (thickness) has
an effect on fuel economy and cold
weather operating (engine start and
engine oil flowability). Lower viscosi-
ty engine oils can provide better fuel
economy and cold weather perform-
ance, however, higher viscosity
engine oils are required for satisfac-
tory lubrication in hot weather.Using oils of any viscosity other than
those recommended could result in
engine damage.
When choosing an oil, consider the
range of temperature your vehicle
will be operated in before the next oil
change. Proceed to select the rec-
ommended oil viscosity from the
chart.
Always be sure to clean the area
around any filler plug, drain
plug, or dipstick before check-
ing or draining any lubricant.
This is especially important in
dusty or sandy areas and when
the vehicle is used on unpaved
roads. Cleaning the plug and
dipstick areas will prevent dirt
and grit from entering the
engine and other mechanisms
that could be damaged.
