When the SRSCM detects a suffi-
ciently severe impact to the front of
the vehicle, it will automatically
deploy the front air bags.Upon deployment, tear seams mold-
ed directly into the pad covers will
separate under pressure from the
expansion of the air bags. Further
opening of the covers allows full
inflation of the air bags.
A fully inflated air bag, in combina-
tion with a properly worn seat belt,
slows the driver's or the front pas-
senger's forward motion, reducing
the risk of head and chest injury.
After complete inflation, the air bag
immediately starts deflating, enabling
the driver to maintain forward visibili-
ty and the ability to steer or operate
other controls.

Driving your vehicle
If you believe your brakes may be wet, apply them lightly whilst driv-
ing until normal braking operation
returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the
water. The best advice is SLOW
DOWN when the road is wet.
The risk of hydroplaning increas-
es as the depth of tyre tread
decreases, refer to "Tyre Tread" in
chapter 7.
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
reduced.
After driving through water, dry the
brakes by gently applying them sev-
eral times whilst the vehicle is mov-
ing slowly.
Highway driving
Tyres
Adjust the tyre inflation, as specified.
Under-inflation may overheat or
damage the tyres.
Do not install worn-out or damaged
tyres, which may reduce traction or
fail the braking operation.
Information
Never over-inflate your tyres above
the maximum inflation pressure, as
specified on your tyres.
Coolant and high voltage bat-tery
Be sure to check both the coolant
level and the high voltage battery
level before driving.

What to do in an emergency
Tyre pressure monitoring sys-
tem
Each tyre should be checked month-
ly when cold and inflated to the infla-
tion 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 infla-
tion pressure label, you should deter-
mine the proper tyre inflation pres-
sure 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.
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

If any of the below happens, have
the system checked by a
HYUNDAI authorised repairer.
1. The Low Tyre Pressure Telltale/TPMS Malfunction Indicator
does not illuminate for 3 sec-
onds when the vehicle is ON.
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 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 15.5 mph
(25 km/h)) until you have the low
pressure tyre repaired and replaced
on the vehicle.

What to do in an emergency
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 a HYUNDAI authorised
repairer 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
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.
WARNING

6-13
What to do in an emergency
6
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, charg-
ers, 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 the
flat tyre be repaired by a HYUNDAI
authorised repairer as soon as pos-
sible or replace the flat tyre with the
spare tyre.Once the original tyre equipped with
a tyre pressure monitoring sensor is
reinflated to the recommended pres-
sure and reinstalled on the vehicle,
the Low Tyre Pressure Telltale and
TPMS Malfunction Indicator will go
off within a few minutes of driving.
If the indicators do not extinguish
after a few minutes, please visit a
HYUNDAI authorised repairer.
Each wheel is equipped with a tyre
pressure sensor mounted inside the
tyre behind the valve stem. You must
use TPMS specific wheels. It is rec-
ommended 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 pres-
sure 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 measur-
ing the inflation pressure. Always be
sure the tyre is cold before inflating
to the recommended pressure.
NOTICE
It is recommended that you do
not use a puncture-repairing
agent not approved by a
HYUNDAI dealer to repair and/or
inflate a low pressure tyre. Tyre
sealant not approved by a
HYUNDAI dealer may damage
the tyre pressure sensor.
CAUTION

6-16
What to do in an emergency
It is possible that some tyres, espe-
cially with larger punctures or dam-
age to the sidewall, cannot be sealed
completely.
Air pressure loss in the tyre may
adversely affect tyre performance.
For this reason, you should avoid
abrupt steering or other driving
manoeuvres, especially if the vehicle
is heavily loaded or if a trailer is in
use.
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 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 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 locat-
ed 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 0.24 inch (6 mm).
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 vehicle ON ( indicator ON).
Otherwise operating the compres-
sor 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 any-
thing to an unconscious person
and seek medical attention imme-
diately.
Long time exposure to the sealant may cause damage to bodily tissue
such as kidney, etc.

What to do in an emergency
7. Plug the compressor power cord (3) into the vehicle power outlet.
8. With the POWER button in the ON position, switch on the compres-
sor and let it run for approximately
5~7 minutes to fill the sealant up
to proper pressure. (Refer to the
Tyre and Wheels, chapter 8).
The inflation pressure of the tyre
after filling is unimportant and will
be checked/corrected later.
Be careful not to overinflate the
tyre and stay away from the tyre
when filling it. 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.
Distributing the sealant
11. Immediately drive approximately 4~6 miles (7~10 km or about 10
minutes) 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 of the side of the road.
Call for road side service or towing.
Do not attempt to drive your
vehicle if the tyre pressure is
below 29 psi (200 kpa). This
could result in an accident due
to sudden tyre failure.

Checking the tyre inflation pres-
sure
1. After driving approximately 4~6miles (7~10 km or about 10 min-
utes), stop at a safe location.
2. Connect the filling hose (2) 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 POWER button ON, pro- ceed as follows.
- To increase the inflation pres- sure:
Switch on the compressor, posi-
tion to "I". To check the current
inflation pressure setting, briefly
switch off the compressor.
- To reduce the inflation pres- sure:
Press the button (8) on the com-
pressor.
Information
The pressure gauge may show higher
than actual reading when the com-
pressor is running. To get an accurate
tyre pressure, the compressor needs to
be turned off.
Information
When reinstalling the repaired or
replaced tyre and wheel on the vehi-
cle, tighten the wheel lug nut to 11~13
kgf·m (79~94 lbf·ft).

Tyre pressure sensor
(if equipped with TPMS)
When you use the Tyre Mobility
Kit including sealant not
approved by HYUNDAI, the tyre
pressure sensors may be dam-
aged by sealant. The sealant on
the tyre pressure sensor and
wheel should be removed when
you replace the tyre with a new
one and inspect the tyre pressure
sensors at an authorised repairer.
