Driving your vehicle
Check battery and cables
The winter temperature increases
the battery consumption. Inspect
the battery and cables, as speci-
fied in the chapter 7. The battery
charging level can be checked by an
authorized HYUNDAI dealer or in a
service station.
Change to "winter weight" oil if
necessary
In some regions during winter, it is
recommended to use the "winter
weight" oil with lower viscosity. For
further information, refer to the chap-
ter 8. When you are not sure about a
type of winter weight oil, consult an
authorized HYUNDAI dealer. Check spark plugs and ignition
system
Inspect the spark plugs, as speci-
fied in the chapter 7.
If necessary,
replace them. Also check all ignition
wirings and components for any
cracks, wear-out, and damage.
To prevent locks from freezing
To prevent the locks from being
frozen, spray approved de-icing fluid
or glycerin into key holes. When a
lock opening is already covered with
ice, spray approved de-icing fluid
over the ice to remove it. When an
internal part of a lock freezes, try to
thaw it with a heated key. Carefully
use the heated key to avoid an injury. Use approved window washer
anti-freeze solution in system
To prevent the window washer from
being frozen, add authorized window
washer anti-freeze solution, as spec-
ified on the window washer contain-
er. Window washer anti-freeze solu-
tion is available from an authorized
HYUNDAI dealer, and so are the
most vehicle accessory outlets. Do
not use engine coolant or other types
of anti-freeze solution to prevent any
damage to the vehicle paint.

If any of the below happens, have
the system checked by an author-
ized HYUNDAI dealer.
1. The Low Tire Pressure Telltale/TPMS Malfunction Indicator
does not illuminate for 3 sec-
onds when the ignition switch
is placed to the ON position or
engine is running.
2. The TPMS Malfunction Indicator remains illuminated after blink-
ing for approximately 1 minute.
3. The Low Tire Pressure Position Telltale remains illuminated.
Low Tire Pressure
Telltale
Low Tire Pressure
Position and Tire
Pressure Telltale
When the tire pressure monitoring
system warning indicators are illumi-
nated and warning message dis-
played on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The Low Tire
Pressure Position Telltale will indi-
cate which tire 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 tires as soon as pos-
sible. Inflate the tires to the proper
pressure as indicated on the vehi-
cle's placard or tire inflation pressure
label located on the driver's side cen-
ter pillar outer panel. If you cannot reach a service station
or if the tire cannot hold the newly
added air, replace the low pressure
tire with the spare tire.
The Low Tire 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
20 minutes at speed above 15.5 mph
(25 km/h)) until you have the low
pressure tire repaired and replaced
on the vehicle.
Information
The spare tire is not equipped with a
tire pressure sensor.

7. Plug the compressor power cord(3) into the vehicle power outlet.
8. With the ignition switch 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
Tire and Wheels, chapter 8). The
inflation pressure of the tire after
filling is unimportant and will be
checked/corrected later.
Be careful not to overinflate the
tire and stay away from the tire
when filling it. 9. Switch off the compressor.
10. Detach the hoses from the
sealant bottle connector and
from the tire valve.
Return the Tire Mobility Kit to its stor-
age location in the vehicle.
Distributing the sealant
11. Immediately drive approximately 4~6miles (7~10km or about 10
minutes) to evenly distribute the
sealant in the tire.
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).
While 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.
What to do in an emergency
Never use a puncture-repairing
agent not approved by HYUNDAI
dealer to repair and/or inflate a
low pressure tire. Tire sealant
not approved by HYUNDAI deal-
er may damage the tire pressure
sensor.
CAUTION
Do not attempt to drive your
vehicle if the tire pressure is
below 29 psi (200kpa). This
could result in an accident due
to sudden tire failure.
CAUTION
Do not leave your vehicle run-
ning in a poorly ventilated area
for extended periods of time.
Carbon monoxide poisoning
and suffocation can occur.
