What to do in an emergency
If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be over-
heating. 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)
and set the parking brake3. Make sure that there is no hot
steam gushing out of the engine
compartment. When it is safe to
do so, open the engine compart-
ment, and check the water-pump
connector. When the water-pump
connector is disconnected, stop
the engine, re-connect the water-
pump connector, and then re-start
the engine.
4. Set the temperature and the air
flow to the maximum, and turn ON
the air conditioner.5. When the Service warning light
( ) illuminates on the instru-
ment cluster, immediately stop the
engine, and contact an authorised
HYUNDAI dealer. When the
engine warning light ( ) illumi-
nates, or when the coolant or hot
steams gush out of the engine
compartment, leave the engine
compartment opened, whilst run-
ning the engine. This is to ventilate
the engine compartment and to
cool down the engine.
6. Check the coolant temperature
gauge on the instrument cluster to
make sure the coolant temperature
is sufficiently cooled down. Check
the coolant level. When it is insuffi-
cient, check its connection with the
radiator, the heater hose, and the
water pump for any leakage. When
there is no leakage, add the
coolant. However, if the problems
persists, such as the illumination of
the warning lights, leakages, or the
cooling-fan malfunction, which may
overheat the engine, immediately
stop the engine, and have your
vehicle checked by an authorised
HYUNDAI dealer.

7. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. 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.
8. Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
we recommend that you call an
authorised HYUNDAI dealer for
assistance.
Serious loss of coolant indi-
cates a leak in the cooling
system and we recommend
the system be checked by an
authorised HYUNDAI dealer.
When the engine overheats
from low engine coolant, sud-
denly adding engine coolant
may cause cracks in the
engine. To prevent damage,
add engine coolant slowly in
small quantities.
CAUTION
Never remove the
engine coolant cap
and/or inverter coolant
cap or the drain plug
whilst the engine and
radiator are hot. Hot coolant and
steam may blow out under pres-
sure, causing serious injury.
Turn the hybrid system off and
wait until the engine cools down.
Use extreme care when remov-
ing the engine coolant cap
and/or inverter coolant cap.
Wrap a thick towel around it, and
turn it anticlockwise 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 anticlockwise to remove
it.

What to do in an emergency
Tyre pressure monitoring sys-
tem
Each tyre, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard 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 pres-
sure 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 sig-
nificantly under-inflated tyre causes
the tyre to overheat and can lead to
tyre failure.
Under-inflation also reduces fuel effi-
ciency 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 mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tyre pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion 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 mal-
function indicator is combined with
the low tyre pressure telltale. When
the system detects a malfunction,
the telltale will flash for approximate-
ly one minute and then remain con-
tinuously illuminated. This sequence
will continue upon subsequent vehi-
cle start-ups as long as the malfunc-
tion exists.
When the malfunction indicator is illu-
minated, the system may not be able
to detect or signal low tyre pressure
as intended. TPMS malfunctions may
occur for a variety of reasons, includ-
ing the installation of replacement or
alternate tyres or wheels on the vehi-
cle that prevent the TPMS from func-
tioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tyres or wheels on your vehicle to
ensure that the replacement or alter-
nate tyres and wheels allow the
TPMS to continue to function proper-
ly.
6
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 con-
trol resulting in an accident.
WARNING

6-16
If any of the below happens, have
the system checked by an autho-
rised HYUNDAI dealer.
1. The Low Tyre Pressure Telltale/
TPMS Malfunction Indicator
does not illuminate for 3 sec-
onds when the ignition switch
is placed to the ON position or
engine is running.
2. The TPMS Malfunction Indicator
remains illuminated after blink-
ing for approximately 1 minute.
3. The Low Tyre Pressure Position
Telltale remains illuminated.
Low tyre pressure
telltale
Low tyre pressure position and
tyre pressure telltale
When the tyre pressure monitoring
system warning indicators are illumi-
nated and a warning message dis-
played on the cluster LCD display,
one or more of your tyres is signifi-
cantly under-inflated. The Low Tyre
Pressure Position Telltale will indi-
cate which tyre is significantly under-
inflated by illuminating the corre-
sponding position light.If either telltale illuminates, immedi-
ately reduce your speed, avoid hard
cornering and anticipate increased
stopping distances. You should stop
and check your tyres as soon as pos-
sible. Inflate the tyres to the proper
pressure as indicated on the vehi-
cle’s placard or tyre inflation pres-
sure label located on the driver’s side
centre pillar outer panel.
If you cannot reach a service station
or if the tyre cannot hold the newly
added air, replace the low pressure
tyre with the spare tyre.
The Low Tyre Pressure Telltale will
remain on and the TPMS Malfunction
Indicator may blink for one minute
and then remain illuminated (when
the vehicle is driven approximately
10 minutes at speed above 25 km/h
(15.5 mph)) until you have the low
pressure tyre repaired and replaced
on the vehicle.

TPMS (Tyre Pressure
Monitoring System)
malfunction indicator
The TPMS Malfunction Indicator will
illuminate after it blinks for approxi-
mately one minute when there is a
problem with the Tyre Pressure
Monitoring System.
We recommend that the system be
checked by an authorised HYUNDAI
dealer as soon as possible.
If there is a malfunction with the
TPMS, the Low Tyre Pressure
Position Telltale will not be dis-
played even though the vehicle
has an under-inflated tyre.
NOTICE
6
In winter or cold weather, the
Low Tyre Pressure Telltale may
be illuminated if the tyre pres-
sure was adjusted to the recom-
mended tyre inflation pressure
in warm weather. It does not
mean your TPMS is malfunc-
tioning because the decreased
temperature leads to a propor-
tional lowering of tyre pressure.
When you drive your vehicle
from a warm area to a cold area
or from a cold area to a warm
area, or the outside temperature
is greatly higher or lower, you
should check the tyre inflation
pressure and adjust the tyres to
the recommended tyre inflation
pressure.
CAUTION
Low pressure damage
Significantly low tyre pressure
makes the vehicle unstable and
can contribute to loss of vehicle
control and increased braking
distances.
Continued driving on low pres-
sure tyres can cause the tyres
to overheat and fail.
