EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
G050100AHM
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in the
maintenance schedule. If the vehicle is
being driven in severe conditions, more
frequent oil and filter changes are
required.
G050200AUN
Drive belts
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.
G050300AFD
Fuel filter (cartridge)
A clogged filter can limit the speed at
which the vehicle may be driven, dam-
age the emission system and cause mul-
tiple issues such as hard starting. If an
excessive amount of foreign matter
accumulates in the fuel tank, the filter
may require replacement more frequent-
ly.
After installing a new filter, run the engine
for several minutes, and check for leaks
at the connections. We recommend that
the fuel filter be replaced by an author-
ized HYUNDAI dealer.
Maintenance
G050400APB
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. We
recommend that the fuel lines, fuel hoses
and connectionsr be replaced by an
authorized HYUNDAI dealer.
WARNING -
Diesel only
Never work on the injection system
with the engine running or within
30 seconds after shutting off the
engine. High pressure pump, rail,
injectors and high pressure pipes
are subject to high pressure even
after the engine stops. The fuel jet
produced by fuel leaks may cause
serious injury, if it touches the
body. People using pacemakers
should not move more than 30cm
closer to the ECU or wiring harness
within the engine room while the
engine is running, since the high
currents in the Common Rail sys-
tem produce considerable magnet-
ic fields.
