Checking the Tire Inflation
Pressure
ODN8H070009N
1. After driving approximately 4~6 miles
(7~10 km or about 10 min), stop at a
safety location.
2. Connect the filling hose (10) of the
compressor directly to the tire valve.
3. Connect between compressor and the
vehicle power outlet using the cable
and connectors.
4. Adjust the tire inflation pressure to the
recommended tire inflation.
With the vehicle in the ready (
)
mode, proceed as follows.
- To increase the inflation pressure:
Switch on the compressor.
To check the current inflation
pressure setting, briefly switch off
the compressor.
- To reduce the inflation pressure:
Press the button (9) on the
compressor.
NOTICE
Do not let the compressor run for more
than 10 minutes, otherwise the device
will overheat and may be damaged.
Information
The pressure gauge may show higher than
actual reading when the compressor is
running. To get an accurate tire pressure,
the compressor needs to be turned off.
CAUTION
If the inflation pressure is not
maintained, drive the vehicle a second
time, refer to Distributing the sealant.
Then repeat steps 1 to 4.
Use of the TMK may be ineffectual for
tire damage larger than approximately
4 mm (0.16 in).
Contact an authorized HYUNDAI dealer
if the tire cannot be made roadworthy
with the Tire Mobility Kit.
WARNING
The tire inflation pressure must be at
least 220 kPa (32 psi). If it is not, do not
continue driving.
Call for road side service or towing.
CAUTION
Tire pressure sensor
The sealant on the tire pressure sensor
and wheel should be removed when
you replace the tire with a new one and
inspect the tire pressure sensors at an
authorized dealer.
Information
When reinstalling the repaired or replaced
tire and wheel on the vehicle, tighten
the wheel lug nut to 79~94 lbf·ft (11~13
kgf·m).

Outward Facing Sidewall
An asymmetrical tire has a particular
side that faces outward when
mounted on a vehicle. The outward
facing sidewall bears white lettering
or bears manufacturer, brand, and/or
model name molding that is higher
or deeper than the same moldings
on the inner facing sidewall.
Passenger (P-Metric) tire
A tire used on passenger cars
and some light duty trucks and
multipurpose vehicles.
Ply
A layer of rubber-coated parallel
cords.
Pneumatic tire
A mechanical device made of rubber,
chemicals, fabric and steel or other
materials, that, when mounted on
an automotive wheel provides the
traction and contains the gas or fluid
that sustains the load.
Pneumatic options weight
The combined weight of installed
regular production options weighing
over 5 lb. (2.3 kg) in excess of the
standard items which they replace,
not previously considered in
curb weight or accessory weight,
including heavy duty breaks, ride
levelers, roof rack, heavy duty
battery, and special trim.
Recommended Inflation Pressure
Vehicle manufacturer’s
recommended tire inflation pressure
as shown on the tire placard.Radial Ply Tire
A pneumatic tire in which the ply
cords that extend to the beads are
laid at 90 degrees to the centerline
of the tread.
Rim
A metal support for a tire and upon
which the tire beads are seated.
Sidewall
The portion of a tire between the
tread and the bead.
Speed Rating
An alphanumeric code assigned to a
tire indicating the maximum speed
at which a tire can operate.
Traction
The friction between the tire and
the road surface. The amount of grip
provided.
Tread
The portion of a tire that comes into
contact with the road.
Treadwear Indicators
Narrow bands, sometimes called
“wear bars”, that show across the
tread of a tire when only 1/16 inch of
tread remains.
UTQGS
Uniform Tire Quality Grading
Standards is a tire information
system that provides consumers
with ratings for a tire’s traction,
temperature and treadwear.
Ratings are determined by tire
manufacturers using government
testing procedures. The ratings are
molded into the sidewall of the tire.

Vehicle Capacity Weight
The number of designated seating
positions multiplied by 150 lbs. (68
kg) plus the rated cargo and luggage
load.
Vehicle Maximum Load on the Tire
Load on an individual tire due to curb
and accessory weight plus maximum
occupant and cargo weight.
Vehicle Normal Load on the Tire
Load on an individual tire that is
determined by distributing to each
axle its share of the curb weight,
accessory weight, and normal
occupant weight and dividing by 2.
Vehicle Placard
A label permanently attached
to a vehicle showing the
original equipment tire size and
recommended inflation pressure.
All Season Tires
HYUNDAI specifies all season
tires on some models to provide
good performance for use all year
round, including snowy and icy
road conditions. All season tires
are identified by ALL SEASON and/
or M+S (Mud and Snow) on the tire
sidewall. Snow tires have better
snow traction than all season tires
and may be more appropriate in
some areas.
Summer Tires
HYUNDAI specifies summer tires on
some models to provide superior
performance on dry roads. Summer
tire performance is substantially
reduced in snow and ice. Summer
tires do not have the tire traction
rating M+S (Mud and Snow) on
the tire side wall. If you plan to
operate your vehicle in snowy or icy
conditions, HYUNDAI recommends
the use of snow tires or all season
tires on all four wheels.
Snow Tires
If you equip your car with snow
tires, they should be the same size
and have the same load capacity as
the original tires. Snow tires should
be installed on all four wheels;
otherwise, poor handling may result.
Snow tires should carry 4 psi (28 kPa)
more air pressure than the pressure
recommended for the standard
tires on the tire label on the driver’s
side of the center pillar, or up to the
maximum pressure shown on the tire
sidewall, whichever is less. Do not
drive faster than 75 mph (120 km/h)
when your vehicle is equipped with
snow tires.
Radial-Ply Tires
Radial-ply tires provide improved
tread life, road hazard resistance
and smoother high speed ride. The
radial-ply tires used on this vehicle
are of belted construction, and are
selected to complement the ride
and handling characteristics of your
vehicle.
