IF THE ENGINE OVERHEATS
F050000AFD-EA
If your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine is probably too hot. If this hap-
pens, you should:
1. Pull off the road and stop as soon as it is safe to do so.
2. Place the gear selector lever in P (automatic transaxle) or neutral (manu-
al transaxle) and set the parking brake.
If the air conditioning is on, turn it off.
3. If engine coolant is running out under the car or steam is coming out from
the bonnet, stop the engine. Do notopen the bonnet until the coolant has
stopped running or the steaming has
stopped. If there is no visible loss of
engine coolant and no steam, leave
the engine running and check to be
sure the engine cooling fan is operat-
ing. If the fan is not running, turn the
engine off.
4. While engine is switched off, check to see if the water pump drive belt is
missing. If it is not missing, check to
see that it is tight. If the drive belt
seems to be satisfactory, check for
coolant leaking from the radiator,
hoses or under the car. (If the air con-
ditioning had been in use, it is normal
for cold water to be draining from it
when you stop). 5. If the water pump drive belt is broken
or engine coolant is leaking out, stop the engine immediately and call the
nearest authorised HYUNDAI dealer
for assistance. 6. If you cannot find the cause of the
overheating, wait until the engine tem-
perature has returned to normal. Then,if coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. If over-heating happens again, call an autho-
rised HYUNDAI dealer for assistance.
CAUTION
Serious loss of coolant indicates
there is a leak in the cooling systemand this should be checked as soonas possible by an authorisedHYUNDAI dealer.
WARNING
While the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out of the
opening and cause serious burns.

EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
G050100AUN Engine oil and filter 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.
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 forproper tension and adjusted as neces-
sary. G050300AFD-EA
Fuel filter (cartridge) 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 authorised HYUNDAI
dealer.
G050400AFD-EA
Fuel lines, fuel hoses and con- nections
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. Have
an authorised HYUNDAI dealer replace
any damaged or leaking parts immedi-
ately.
WARNING -
Diesel only
Never work on injection system with engine running or within 30
seconds after shutting off engine.
High pressure pump, rail, injectorsand high pressure pipes are sub-
ject to high pressure even after the
engine stopped. The fuel jet pro-
duced by fuel leaks may cause seri-
ous injury, if it touch the body.
People using pacemakers should
not move than 30cm closer to theECU or wiring harness within the
engine room while engine is run-
ning, since the high currents in the
Common Rail system produce con-
siderable magnetic fields.
