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 brake 3. 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 a HYUNDAI
authorised repairer. 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 a HYUNDAI
authorised repairer.

Whilst the engine is
running, keep hands,
clothing and tools
away from the mov-
ing parts such as the
cooling fan and drive
belt to prevent seri-
ous injury.

7. If you cannot find the cause of theoverheating, 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 a
HYUNDAI authorised repairer for
assistance.
Serious loss of coolant indi-
cates a leak in the cooling
system and we recommend
the system be checked by a
HYUNDAI authorised repairer.
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 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.

The Tyre Mobility Kit is not designed
or intended as a permanent tyre
repair method and is to be used for
one tyre only.
This instruction shows you step by
step how to temporarily seal the
puncture simply and reliably.
Read the section "Notes on the safe
use of the Tyre Mobility Kit".Notes on the safe use of theTyre 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 will not move, even when you’re on fairly
level ground, always set your park-
ing 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, bicy- cles or any other type of tyres.
When the tyre and wheel are dam- aged, 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 6 mm (0.24 inch).
Please contact the nearest
HYUNDAI dealership if the tyre
cannot be made roadworthy with
the Tyre Mobility Kit.
Do not use the Tyre Mobility Kit if a tyre is severely damaged by driving
run flat or with insufficient air pres-
sure. 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 run- ning for more than 10 minutes at a
time or it may overheat.
Do not use the Tyre Mobility Kit if the ambient temperature is below
-30°C (-22°F).
In case of skin contact with the sealant, wash the area thoroughly
with plenty of water. If the irritation
persists, seek medical attention.
In case of eye contact with the sealant, flush your eyes for at least
15 minutes. If the irritation persists,
seek medical attention.
In case of swallowing the sealant, rinse the mouth and drink plenty of
water. However, never give anything
to an unconscious person and seek
medical attention immediately.
Long time exposure to the sealant may cause damage to bodily tissue
such as kidney, etc.
Do not use the TMK if a tyre is
severely damaged by driving
run flat or with insufficient air
pressure.
Only punctured areas located
within the tread region of the
tyre can be sealed using the
TMK.

MaintenanceThe electric motor for the cooling fan
is controlled by engine coolant tem-
perature, refrigerant pressure and
vehicle speed. As the engine coolant
temperature decreases, the electric
motor will automatically shut off. This
is a normal condition. If your vehicle
is equipped with GDI, the electric
motor for the cooling fan may begin
to operate at any time and continue
to operate until you disconnect the
negative battery cable.The electric motor for
the cooling fan may
continue to operate
or start up when the
engine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan blades
of the cooling fan.
WARNING
Make sure the coolant cap is
properly closed after refilling
coolant. Otherwise the engine
could be overheated whilst
driving.
1. Check if the coolant cap label is straight In front.

Checking the hybrid starter &
generator (HSG) belt
We recommend that you have the
hybrid starter & generator (HSG)
belt inspected or replaced according
to the Maintenance Schedule by a
HYUNDAI authorised repairer.
Checking the brake fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap
and adding brake fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-
ination.
Turn the vehicle off whilst you
inspect the engine or hybrid
starter & generator(HSG) belt.
Otherwise it may result in
serious injury.
Keep hands, clothing etc.
away from the hybrid starter &
generator (HSG) belt.
WARNING
When the HSG belt is worn out or
damaged, replace the belt.
Otherwise, it may cause engine
overheating or battery discharge.
