Maintenance
Vacuum crankcase ventilation hoses
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. Particular attention
should be paid to examine those hose
surfaces nearest to high heat sources,
such as the exhaust manifold. Inspect the hose routing to assure that the hoses do not come in contact with
any heat source, sharp edges or movingcomponent which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.
Air cleaner filter
A Genuine HYUNDAI air cleaner filter isrecommended when the filter is replaced.
Spark plugs
Make sure to install new spark plugs of
the correct heat range.
Valve clearance
Inspect for excessive valve noise and/or
engine vibration and adjust if necessary.
An authorized HYUNDAI dealer should
perform the operation.
Cooling system
Check for cooling system components,
such as radiator, coolant reservoir, hoses
and connections for leakage and dam-
age. Replace any damaged parts.
Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Manual transaxle fluid (if equipped)
Inspect the manual transaxle fluid
according to the maintenance schedule.
Automatic transaxle fluid (if equipped)
Automatic transaxle fluid should not be
checked under normal usage conditions.
But in severe conditions, the fluid should
be changed at an authorized HYUNDAIdealer in accordance to the scheduledmaintenance at the beginning of this
chapter.
✽✽NOTICE
Automatic transaxle fluid color is basi-
cally red.
As the vehicle is driven, the automatic
transaxle fluid will begin to look darker.
It is normal condition and you should
not judge the need to replace the fluid
based upon the changed color.

Maintenance
Checking the parking brake
Type A
Check whether the stroke is within spec-
ification 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 fair-
ly steep grade. If the stroke is more or
less than specified, have the parking
brake adjusted by an authorized
HYUNDAI dealer.
Stroke : 4 notch
Type B
Check the stroke of the parking brake by
counting the number of “clicks’’ heardwhile fully applying it from the released
position. Also, the parking brake alone
should securely hold the vehicle on a fair-
ly 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).
