Checking the Brake 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 fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-
ination. If the level is low, add the specified
brake fluid to the MAX level. The level
will fall with accumulated mileage.
This is a normal condition associated
with the wear of the brake linings. If
the fluid level is excessively low, have
the brake system checked by an
authorized HYUNDAI dealer.
Do not allow brake fluid to con-
tact the vehicle’s body paint, as
paint damage will result.
Brake 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 fluid. A few drops of min-
eral based oil, such as engine
oil, in your brake system can
damage brake system parts.
Information
Use only the specified brake fluid
(refer to "Recommended Lubricants
and Capacities" in chapter 8).
i
NOTICE
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 fluid to come
in contact with your eyes. If
brake 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
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
Foot type
Check whether the stroke is within
specification when the parking brake
pedal is depressed with 44 lb (20 kg,
196 N) of force. 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 : 3 notch

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. Replace the air cleaner filter. 5. Pull up the lever (1) to the LOCK position.
6. Rise up the cover (2) until the hooks on the cover are securely
fastened into the latches (3).
7. Check if the cover is firmly installed.
Information
If the vehicle is operated in extremely
dusty or sandy areas, replace the air
cleaner filter more often than the
usual recommended 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.

Filter Inspection
The climate control air filter should
be replaced according to the
Maintenance Schedule. If the vehicle
is operated in severely air-polluted
cities or on dusty rough roads for a
long period, it should be inspected
more frequently and replaced earlier.
When you replace the climate control
air filter, replace it performing the fol-
lowing procedure, and be careful to
avoid damaging other components.
1. With the glove box open, removethe stoppers on both sides to
allow the glove box to hang freely
on the hinges. 2. Remove the support rod (1).

3. Remove the climate control air fil- ter case while pressing the lock on
the right side of the cover. 4. Replace the climate control air fil-
ter.
5. Reassemble in the reverse order of disassembly. Install a new climate control air fil-
ter in the correct direction with the
arrow symbol (

wards. Otherwise, the climate con-
trol effects may decrease, possi-
bly with a noise.

Blade Inspection
Contamination of either the wind-
shield or the wiper blades with for-
eign matter can reduce the effective-
ness of the windshield wiper func-
tionality. Common sources of con-
tamination are insects, tree sap, and
hot wax treatments used by some
commercial car washes. If the blades
are not wiping properly, clean both
the window and the blades with a
clean cloth dampened with washer
fluid. To prevent damage to the wiper
blades, arms or other compo-
nents, do not:
Use gasoline, kerosene, paint
thinner, or other solvents on or
near them.
Attempt to move the wipers manually.
Use non-specified wiper blades.
Information
Commercial hot waxes applied by auto-
matic car washes have been known to
make the windshield difficult to clean.
Blade Replacement
When the wipers no longer clean
adequately, the blades may be worn
or cracked, and require replacement.
To prevent damage to the wiper
arms or other components, do not
attempt to move the wipers manu-
ally.
The use of a non-specified wiper
blade could result in wiper mal-
function and failure.
In order to prevent damage to the hood and the wiper arms, the
wiper arms should only be lifted
when in the top wiping position.
Always return the wiper arms to the windshield before driving.
