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.

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.

Changing tyres
WARNING
A vehicle can slip or roll off of a jack
causing serious injury or death to you
or those nearby. Take the following
safety precautions:

[Do not get under a vehicle that is
supported by a jack.

[NEVER attempt to change a tyre in
the lane of traffic. ALWAYS move the
vehicle completely off the road on
level, firm ground away from traffic
before trying to change a tyre. If you
cannot find a level, firm place off
the road, call a towing service for
assistance.

[Be sure to use the jack provided with
the vehicle.

[ALWAYS place the jack on the
designated jacking positions on the
vehicle and NEVER on the bumpers
or any other part of the vehicle for
jacking support.

[Do not start or run the engine whilst
the vehicle is on the jack.

[Do not allow anyone to remain in the
vehicle whilst it is on the jack.

[Keep children away from the road
and the vehicle.
Follow these steps to change your
vehicle’s tyre:
1. Park on a level, firm surface.
2. Move the shift lever into P (Park, for
automatic transmission/dual clutch
transmission vehicle) or neutral
(for manual transmission vehicle),
apply the parking brake, and place
the ignition switch in the LOCK/OFF
position.
3. Press the hazard warning flasher
button.
4. Remove the wheel lug nut wrench,
jack, jack handle, and spare tyre from
the vehicle.
OBC3080005
[A] : Block
5. Block both the front and rear of the
tyre diagonally opposite of the tyre
you are changing.
OBC3080006
6. Loosen the wheel lug nuts
counterclockwise one turn each in
the order shown above, but do not
remove any lug nuts until the tyre has
been raised off of the ground.

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).

5. Insert the sealant bottle into the
housing (5) of the compressor so that
the bottle is upright.
6. Ensure that the compressor is
switched off, position 0.
OBC3080011
NOTICE
Securely install the sealant filling hose
to the valve. If not, sealant may flow
backward, possibly clogging the filling
hose.
OBC3N080005
7. Connect between compressor and the
vehicle power outlet using the cable
and connectors (4).
8. With the engine start/stop button
position on or ignition switch position
on, switch on the compressor and let
it run for approximately 5~7 minutes to
fill the sealant up to proper pressure.
(refer to immediately chapter 2).
The inflation pressure of the tyre
immediately filling is unimportant and
will be checked/corrected later.
Be careful not to overinflate the tyre
and stay away from the tyre whilst
filling it.
NOTICE
- Tyre pressure
Do not attempt to drive your vehicle
if the tyre pressure is below 29
PSI(200kpa). This could result in an
accident due to sudden tyre failure.
9. Switch off the compressor.
10. Detach the hoses from the sealant
bottle connector and from the tyre
valve.
Return the Tyre Mobility Kit to its storage
location in the vehicle.
