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 transmission) or neutral
(manual transmission) 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 not
open 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. Whilst 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 we recom-
mend that you call an authorised
HYUNDAI dealer.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, we recom-
mend that you call an authorised
HYUNDAI dealer.
CAUTION
• Serious loss of coolant indicates
there is a leak in the cooling sys-
tem and we recommend that the
system be checked by an autho-
rised HYUNDAI dealer.
• When the engine overheats from
low engine coolant, suddenly
adding engine coolant may cause
cracks in the engine. To prevent
damage, add engine coolant
slowly in small quantities.
WARNING
Whilst 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.

WARNING- Maintenance
work
• Performing maintenance work on
a vehicle can be dangerous. You
can be seriously injured whilst
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, we recommend that the
system be servied by an autho-
rised HYUNDAI dealer.
• Working under the bonnet with
the engine running is dangerous.
It becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine whilst work-
ing under the bonnet, make cer-
tain that you remove all jewelry
(especially rings, bracelets,
watches, and necklaces) and all
neckties, scarves, and similar
loose clothing before getting
near the engine or cooling fans.WARNING- Diesel Engine
Never work on injection system
with engine running or within 30
seconds after shutting off engine.
High-pressure pump, rail, injectors
and 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 touches the body.
People using pacemakers should
not move than 30cm closer to the
ECU or wiring harness within the
engine room whilst engine is run-
ning, since the high currents in the
electronic engine control system
produce considerable magnetic
fields.
CAUTION
• Do not put heavy objects or apply
excessive force on top of the
engine cover (if equipped) or fuel
related parts.
• When you inspect the fuel system
(fuel lines and fuel injection
devices), we recommend that you
contact an authorised HYUNDAI
dealer.
• Do not drive long time with the
engine cover(if equipped)
removed.
• When checking the engine room,
do not go near fire. Fuel, washer
fluid, etc. are flammable oils that
may cause fire.
• Before touching the battery, igni-
tion cables and electrical wiring,
you should disconnect the bat-
tery "-" terminal. You may get an
electric shock from the electric
current.
• When you remove the interior
trim cover with a flat head (-) driv-
er, be careful not to damage the
cover.
• Be careful when you replace and
clean bulbs to avoid burns or
electrical shock.

If the diesel fuel specifications don't meet the EN590, it must be replaced more frequently. HYUNDAI recommends "every
7,500km inspection, every 15,000km replacement". If there are some important safety matters like fuel flow restriction, surging,
loss of power, hard starting problem etc., replace the fuel filter immediately regardless of maintenance schedule and consult an
authorised HYUNDAI dealer for details.
*
5: The fuel filter is considered to be maintenance free but periodic inspection is recommended for this maintenance schedule
depends on fuel quality. If there are some important safety matters like fuel flow restriction, surging, loss of power, hard start-
ing problem etc, replace the fuel filter immediately regardless of maintenance schedule and consult an authorised HYUNDAI
dealer for details.
*
6: When adding coolant, use only deionized water or soft water for your vehicle and never mix hard water in the coolant filled at
the factory. An improper coolant mixture can result in serious malfunction or engine damage.

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.

WARNING
Used engine oil may cause irrita-
tion or cancer of the skin if left in
contact with the skin for prolonged
periods of time. Used engine oil
contains chemicals that have
caused cancer in laboratory ani-
mals. Always protect your skin by
washing your hands thoroughly
with soap and warm water as soon
as possible after handling used oil.

WARNING
Removing radiator
cap
• Never attempt to remove the radi-
ator cap whilst the engine is
operating or hot. Doing so might
lead to cooling system and
engine damage and could result
in serious personal injury from
escaping hot coolant or steam.
• Turn the engine off and wait until
it cools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop. Step back whilst
the pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the cap,
using a thick towel, and continue
turning counterclockwise to
remove it.
(Continued)CAUTION
• Do not drive with no engine
coolant. It may cause water pump
failure and engine seizure, etc.
• When the engine overheats from
low engine coolant, suddenly
adding engine coolant may cause
cracks in the engine. To prevent
damage, add engine coolant
slowly in small quantities.

Maintenance
Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F and L marks on the side of the
coolant reservoir when the engine is
cool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F, but do not overfill. If frequent
additions are required, we recommend
that the system be inspected by an
authorised HYUNDAI dealer.
G070101BUN-EA
Recommended engine coolant
• When adding coolant, use only deion-
ized water or soft water for your vehicle
and never mix hard water in the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
• The engine in your vehicle has alu-
minium engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-
ing.
• DO NOT USE alcohol or methanol
coolant or mix them with the specified
coolant.
• Do not use a solution that contains
more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.
For mixture percentage, refer to the fol-
lowing table.
OTQ077004
(Continued)
• Even if the engine is not operat-
ing, do not remove the radiator
cap or the drain plug whilst the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.
WARNING
The electric motor (cool-
ing fan) is controlled by
engine coolant tempera-
ture, refrigerant pres-
sure and vehicle speed.
It may sometimes operate even
when the engine is not running.
Use extreme caution when working
near the blades of the cooling fan
so that you are not injured by a
rotating fan blades. As the engine
coolant temperature decreases, the
electric motor will automatically
shut off. This is a normal condition.
