Maintenance
EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
Fuel filter
Vapor hose and fuel filler cap
The   engine   oil  and   filter   should   be
changed at the  intervals specified in  the
maintenance schedule. If the car is being
driven  in  severe   conditions,  more  fre-
quent oil and filter changes are required.
A  clogged  filter  can limit  the  speed  at
which the vehicle may be driven, damage
the emission system  and cause multiple
issues such as hard starting. If an exces-
sive  amount of  foreign  matter  accumu-
lates  in   the  fuel   tank,  the   filter  may
require replacement more frequently.
After installing a new filter, run the engine
for several  minutes, and check  for leaks
at the connections. Fuel filters should  be
installed   by  an   authorized   HYUNDAI
dealer.
The vapor hose and fuel filler cap should
be inspected at  those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler  cap is
correctly replaced.
Drive belts
Vacuum crankcase ventilation
hoses
Inspect  all  drive  belts   for  evidence  of
cuts, cracks,  excessive wear or  oil satu-
ration  and  replace   if  necessary.  Drive
belts should  be checked  periodically for
proper  tension and  adjusted  as  neces-
sary.
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 moving
component 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.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and con-
nections for  leakage and damage.  Have
an authorized  HYUNDAI  dealer replace
any  damaged or  leaking  parts  immedi-
ately.
