Emergency situations
Jump starting can be dangerous if done
incorrectly. Follow the jump starting
procedure in this section to avoid serious
injury or damage to your vehicle. If in
doubt about how to properly jump start
your vehicle, we strongly recommend
that you have a service technician or
towing service do it for you.
WARNING
To prevent SERIOUS INJURY or DEATH
to you or bystanders, always follow
these precautions when working near
or handling the battery:
Always read and follow
instructions carefully when
handling a battery.
Wear eye protection designed
to protect the eyes from acid
splashes.
Keep all flames, sparks, or
smoking materials away from
the battery.
Hydrogen is always present in
battery cells, is highly
combustible, and may explode
if ignited.
Keep batteries out of reach of
children.
Batteries contain sulfuric acid
which is highly corrosive. Do
not allow acid to contact your
eyes, skin or clothing.
If acid gets into your eyes, flush your
eyes with clean water for at least 15
minutes and get immediate medical
attention. If acid gets on your skin,
thoroughly wash the area. If you
feel pain or a burning sensation, get
medical attention immediately.

[When lifting a plastic-cased battery,
excessive pressure on the case may
cause battery acid to leak. Lift with a
battery carrier or with your hands on
opposite corners.

[Do not attempt to jump start your
vehicle if your battery is frozen.

[NEVER attempt to recharge the
battery when the vehicle’s battery
cables are connected to the battery.

[The electrical ignition system works
with high voltage. NEVER touch these
components with the engine running
or when the ignition switch is in the
ON position.

[Do not allow the (+) and (-) jumper
cables to touch. It may cause sparks.

[The battery may rupture or explode
when you jump start with a low or
frozen battery.
NOTICE
To prevent damage to your vehicle:

[Only use a 12-volt power supply
(battery or jumper system) to jump
start your vehicle.

[Do not attempt to jump start your
vehicle by push-starting.

An inappropriately disposed
battery can be harmful to the
environment and human
health. Dispose of the battery
according to your local law(s)
or regulations.
Jump starting procedure
1. Position the vehicles close enough
that the jumper cables will reach, but
do not allow the vehicles to touch.
2. Avoid fans or any moving parts in the
engine compartment at all times, even
when the vehicles are turned off.
3. Turn off all electrical devices such
as radios, lights, air conditioning,
etc. Put the vehicles in P (Park, for
automatic transmission/dual clutch
transmission vehicle) or neutral (for
manual transmission vehicle), and set
the parking brakes. Turn both vehicles
OFF.1VQA4001
4. Connect the jumper cables in
the exact sequence shown in the
illustration. First connect one jumper
cable to the red, positive (+) jumper
terminal of your vehicle (1).
5. Connect the other end of the jumper
cable to the red, positive (+) battery/
jumper terminal of the assisting
vehicle (2).
6. Connect the second jumper cable to
the black, negative (-) battery/ chassis
ground of the assisting vehicle (3).
7. Connect the other end of the second
jumper cable to the black, negative (-)
chassis ground of your vehicle (4).
Do not allow the jumper cables to
contact anything except the correct
battery or jumper terminals or the
correct ground. Do not lean over the
battery when making connections.
8. Start the engine of the assisting
vehicle and let it run at approximately
2,000rpm for a few minutes. Then
start your vehicle.
If your vehicle will not start after a
few attempts, it probably requires
servicing. In this event, please seek
qualified assistance. If the cause of your
battery discharging is not apparent, we
recommend that you have your vehicle
checked by a HYUNDAI authorised
repairer.

Emergency situations
Disconnect the jumper cables in the
exact reverse order you connected
them:
1. Disconnect the jumper cable from the
black, negative (-) chassis ground of
your vehicle (4).
2. Disconnect the other end of the
jumper cable from the black, negative
(-) battery/chassis ground of the
assisting vehicle (3).
3. Disconnect the second jumper cable
from the red, positive (+) battery/
jumper terminal of the assisting
vehicle (2).

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.

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.

Low tyre pressure
warning light
Low tyre pressure position and
tyre pressure telltale
ONX4E040019
When the tyre pressure monitoring
system warning indicators are
illuminated and a warning message
displayed on the cluster LCD display,
one or more of your tyres is significantly
under-inflated. The Low Tyre Pressure
Position Telltale will indicate which
tyre is significantly underinflated by
illuminating the corresponding position
light.
If either telltale illuminates, immediately
reduce your speed, avoid hard cornering
and anticipate increased stopping
distances. You should stop and check
your tyres as soon as possible. Inflate the
tyres to the proper pressure as indicated
on the vehicle’s placard or tyre inflation
pressure 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 15.5 mph (25
km/h)) until you have the low pressure
tyre repaired and replaced on the
vehicle.
CAUTION
In winter or cold weather, the Low Tyre
Pressure Telltale may be illuminated if
the tyre pressure was adjusted to the
recommended tyre inflation pressure
in warm weather. It does not mean
your TPMS is malfunctioning because
the decreased temperature leads to a
proportional 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.
WARNING
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 pressure
tyres can cause the tyres to overheat
and fail.

8-14
Emergency situations
TPMS (Tyre Pressure
Monitoring System)
malfunction indicator
The TPMS Malfunction Indicator
will illuminate after it blinks for
approximately one minute when there
is a problem with the Tyre Pressure
Monitoring System.
We recommend that you have the
system checked by a HYUNDAI
authorised repairer as soon as possible.
NOTICE
If there is a malfunction with the TPMS,
the Low Tyre Pressure Position Telltale
will not be displayed even though the
vehicle has an under-inflated tyre.
NOTICE
The TPMS Malfunction Indicator may
illuminate after blinking for one minute
if the vehicle is near electric power
supply cables or radio transmitters
such as police stations, government
and public offices, broadcasting
stations, military installations, airports,
transmitting towers, etc.
Additionally, the TPMS Malfunction
Indicator may illuminate if snow chains
are used or electronic devices such as
computers, chargers, remote starters,
navigation, etc. This may interfere with
normal operation of the TPMS.
Changing a tyre with TPMS
If you have a flat tyre, the Low Tyre
Pressure and Position telltales will come
on. We recommend that you have
the flat tyre repaired by a HYUNDAI
authorised repairer as soon as possible
or replace the flat tyre with the spare
tyre.
NOTICE
It is recommended that you do not
use a puncture-repairing agent not
approved by HYUNDAI dealer or the
equivalent specified for your vehicle
to repair and/or inflate a low pressure
tyre. Tyre sealant not approved by
HYUNDAI dealer or the equivalent
specified for your vehicle may damage
the tyre pressure sensor.
The spare tyre (if equipped) does not
come with a tyre pressure monitoring
sensor. When the low pressure tyre or
the flat tyre is replaced with the spare
tyre, the Low Tyre Pressure Telltale will
remain on. Also, the TPMS Malfunction
Indicator will illuminate after blinking
for one minute if the vehicle is driven
at speed above 15.5 mph (25 km/h) for
approximately 10 minutes.
Once the original wheel equipped with
a tyre pressure monitoring sensor is
reinflated to the recommended pressure
and reinstalled on the vehicle, the
Low Tyre Pressure Telltale and TPMS
Malfunction Indicator will go off within a
few minutes of driving.
❈ All vehicles sold in the EUROPE
market during below period must be
equipped with TPMS.
- New model vehicle : Nov. 1, 2012 ~
- Current model vehicle : Nov. 1, 2014~
(Based on vehicle registrations)

8-15
08
If the indicators do not extinguish after
a few minutes, it is recommended to
contact the nearest authorised HYUNDAI
dealer.
Each wheel is equipped with a tyre
pressure sensor mounted inside the tyre
behind the valve stem (except for the
spare tyre). You must use TPMS specific
wheels. It is recommended that you
always have your tyres serviced by a
HYUNDAI authorised repairer.
You may not be able to identify a tyre
with low pressure by simply looking at it.
Always use a good quality tyre pressure
gauge to measure. Please note that a
tyre that is hot (from being driven) will
have a higher pressure measurement
than a tyre that is cold.
A cold tyre means the vehicle has been
sitting for 3 hours and driven for less
than 1 mile (1.6 km) in that 3 hour period.
Allow the tyre to cool before measuring
the inflation pressure. Always be sure
the tyre is cold before inflating to the
recommended pressure.
WARNING

[The TPMS cannot alert you to severe
and sudden tyre damage caused by
external factors such as nails or road
debris.

[If you feel any vehicle instability,
immediately take your foot off
the accelerator, apply the brakes
gradually with light force, and slowly
move to a safe position off the road.
WARNING
Tampering with, modifying, or disabling
the Tyre Pressure Monitoring System
(TPMS) components may interfere
with the system’s ability to warn the
driver of low tyre pressure conditions
and/or TPMS malfunctions. Tampering
with, modifying, or disabling the Tyre
Pressure Monitoring System (TPMS)
components may void the warranty for
that portion of the vehicle.
WARNING

[Do not modify the vehicle; it may
interfere with the TPMS function.

[The wheels on the market do not
have a TPMS sensor.

[For your safety, we recommend that
you use parts for replacement from a
HYUNDAI authorised repairer.

[If you use the wheels on the market,
use a TPMS sensor approved by a
HYUNDAI dealer or the equivalent
approved for your vehicle. If your
vehicle is not equipped with a TPMS
sensor or TPMS does not work
properly, you may fail the periodic
vehicle inspection conducted in your
country.
