Safety system
How does the air bags system
operate?
OBC3030023R
The SRS consists of the following
components:
(1) Driver’s front air bag module
(2) Passenger’s front air bag module*
(3) Side air bag modules*
(4) Curtain air bag modules*
(5) Retractor pre-tensioner assemblies*
(6) Air bag warning light
(7) SRS control module (SRSCM)
(8) Front impact sensors
(9) Side impact sensors*
(10) Side pressure sensors*
(11) Passenger’s front air bag OFF
indicator (front passenger’s seat
only) *
(12) Passenger’s front air bag ON/OFF
switch *
* : if equipped
The SRSCM continually monitors SRS
components whilst the ignition switch
is in the ON position to determine if a
crash impact is severe enough to require
air bag deployment or pre-tensioner seat
belt deployment.
SRS warning light
The SRS (Supplement Restraint System)
air bag warning light on the instrument
panel displays the air bag symbol
depicted in the illustration. The system
checks the air bag electrical system for
malfunctions. The light indicates that
there is a potential problem with your air
bag system.
WARNING
If your SRS malfunctions, the air bag
may not inflate properly during an
accident increasing the risk of serious
injury or death.
If any of the following conditions occur,
your SRS is malfunctioning:

[The light does not turn on for
approximately six seconds when the
ignition switch is in the ON position.

[The light stays on after illuminating
for approximately six seconds.

[The light comes on whilst the vehicle
is in motion.

[The light blinks when the engine is
running.
We recommend that a HYUNDAI
authorised repairer inspect the SRS
as soon as possible if any of these
conditions occur.

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).

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.

Do not leave your vehicle running in
a poorly ventilated area for extended
periods of time.
Carbon monoxide poisoning and
suffocation can occur.
Distributing the sealant
11. Immediately drive approximately
4~6miles (7~10km or, about 10 mins)
to evenly distribute the sealant in the
tyre.
Do not exceed a speed of 50 mph (80
km/h). If possible, do not fall below a
speed of 12 mph (20 km/h).
Whilst driving, if you experience any
unusual vibration, ride disturbance or
noise, reduce your speed and drive with
caution until you can safely pull off the
vehicle on the side of the road.
Call for road side service or towing.
When you use the Tyre Mobility Kit, the
tyre pressure valve and wheel may be
damaged by sealant, remove the sealant
stained. We recommend that the tyre
pressure valve and wheel be inspected
by an authorized HYUNDAI dealer.

Checking the tyre inflation
pressure
1. After driving approximately 4 ~6miles
(7~10km or about 10min), stop at a
safety location.
2. Connect connection hose (10) of the
compressor directly to the tyre valve.
3. Plug the compressor power cord into
the vehicle power outlet.
4. Adjust the tyre inflation pressure to
the recommended tyre inflation.
With the ignition switched on, proceed
as follows.
- To increase the inflation pressure :
Switch on the compressor, position
I. To check the current inflation
pressure setting, briefly switch off
the compressor.
i Information
The pressure gauge may show higher than
actual reading when the compressor is
running. To get an accurate tyre pressure,
the compressor needs to be turned off.
NOTICE
- Tyre pressure valve
We recommend that you use the
sealant of tyre mobility kit from a
HYUNDAI authorised repairer. The
sealant on the tyre pressure valve and
wheel should be removed when you
replace the tyre with a new one and
we recommend that the tyre pressure
valve be inspected by an authorized
HYUNDAI dealer.
