2023 HYUNDAI I20 engine overheat

8-9
08
If your temperature gauge indicates
overheating, you experience a loss of
power, or hear loud pinging or knocking,
the engine may be overheating. If this
happens, you should:
1. Pull off the road and stop as soon as it
is safe to do so.
2. Place the shift lever in P (Park, for
automatic transmission/dual clutch
transmission vehicle) or neutral (for
manual transmission/dual clutch
transmission vehicle) and set the
parking brake. If the air conditioning is
ON, turn it OFF.
3. If engine coolant is running out under
the vehicle 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
operating. If the fan is not running,
turn the engine off.
WARNING
Whilst the engine is
running, keep hands,
clothing and tools away
from the moving parts such
as the cooling fan and drive
belt to prevent serious
injury.4. Check for coolant leaking from the
radiator, hoses or under the vehicle. (If
the air conditioning had been in use, it
is normal for cold water to be draining
from it when you stop.)
5. If engine coolant is leaking out, stop
the engine immediately and we
recommend that you call a HYUNDAI
authorised repairer for assistance.
WARNING
NEVER remove the radiator
cap or the drain plug whilst
the engine and radiator are
hot. Hot coolant and steam
may blow out under
pressure, causing serious injury.
Turn the engine off and wait until the
engine 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.

Emergency situations
6. If you cannot find the cause of the
overheating, wait until the engine
temperature 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 overheating happens again, we
recommend that you call a HYUNDAI
authorised repairer for assistance.

add engine coolant slowly in small
quantities.

Emergency situations
Tyre pressure monitoring
system
WARNING
Over-inflation or under-inflation can
reduce tyre life, adversely affect
vehicle handling, and lead to sudden
tyre failure that may cause loss of
vehicle control resulting in an accident.
Each tyre, including the spare (if
provided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
or tyre inflation pressure label. (If your
vehicle has tyres of a different size
than the size indicated on the vehicle
placard or tyre inflation pressure label,
you should determine the proper tyre
inflation pressure for those tyres.)
As an added safety feature, your
vehicle has been equipped with a tyre
pressure monitoring system (TPMS)
that illuminates a low tyre pressure
telltale when one or more of your
tyres is significantly under-inflated.
Accordingly, when the low tyre pressure
telltale illuminates, you should stop and
check your tyres as soon as possible,
and inflate them to the proper pressure.
Driving on a significantly under-inflated
tyre causes the tyre to overheat and can
lead to tyre failure.
Under-inflation also reduces fuel
efficiency and tyre tread life, and
may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tyre maintenance,
and it is the driver’s responsibility to
maintain correct tyre pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low
tyre pressure telltale.
Your vehicle has also been equipped
with a TPMS malfunction indicator
to indicate when the system is
not operating properly. The TPMS
malfunction indicator is combined with
the low tyre pressure telltale. When
the system detects a malfunction, the
telltale will flash for approximately one
minute and then remain continuously
illuminated. This sequence will continue
upon subsequent vehicle start-ups as
long as the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tyre pressure as
intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tyres or wheels on the vehicle that
prevent the TPMS from functioning
properly.
Always check the TPMS malfunction
telltale after replacing one or more tyres
or wheels on your vehicle to ensure that
the replacement or alternate tyres and
wheels allow the TPMS to continue to
function properly.
NOTICE
If any of the below happens, we
recommend that you have the system
checked by a HYUNDAI authorised
repairer.
1. The Low Tyre Pressure Telltale/
TPMS Malfunction Indicator does not
illuminate for 3 seconds when the
Engine Start/Stop button is pressed
to the ON position or when the
engine is running.
2. The TPMS Malfunction Indicator
remains illuminated after blinking for
approximately 1 minute.
3. The Low Tyre Pressure Position
Telltale remains illuminated.

Notes on the safe use of the
Tyre Mobility Kit

[Park your car at the side of the road
so that you can work with the Tyre
Mobility Kit away from moving traffic.

[To be sure your vehicle does not
move, even when you're on fairly level
ground, always set your parking brake.

[Only use the Tyre Mobility Kit for
sealing/inflation passenger car tyres.
Only punctured areas located within
the tread region of the tyre can be
sealed using the tyre mobility kit.

[Do not use on motorcycles, bicycles or
any other type of tyres.

[When the tyre and wheel are
damaged, do not use Tyre Mobility Kit
for your safety.

[Use of the Tyre Mobility Kit may not be
effective for tyre damage larger than
approximately 0.24 in (6 mm).
We recommend that you contact a
HYUNDAI authorised repairer.
[Do not use the Tyre Mobility Kit
if a tyre is severely damaged by
driving run flat or with insufficient air
pressure.

[Do not remove any foreign objects
such as nails or screws that have
penetrated the tyre.

[Provided the car is outdoors, leave the
engine running. Otherwise operating
the compressor may eventually drain
the car battery.

[Never leave the Tyre Mobility Kit
unattended whilst it is being used.

[Do not leave the compressor running
for more than 10 min. at a time or it
may overheat.

[Do not use the Tyre Mobility Kit if the
ambient temperature is below -22°F
(-30°C).
