What to do in an emergency
36 6
Checking the tire inflation
pressure
1. After driving approximately 7 ~ 10
km (4 ~ 6 miles or about 10 min),
stop at a safe location.
2. Connect the filling hose (3) of the
compressor (clip mounted side)
directly and then connect the fill
ing hose (3) (opposite side) 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 cold tire recommended pres-
sure as indicated on the vehicle’s
placard or tire inflation pressure
label located on the driver’s side
center pillar outer panel. (Refer to
“Tires and wheels” in chapter 8.)
- To increase the inflation pres-
sure :Switch on the compres-
sor, position I. To check the cur-
rent inflation pressure setting,
briefly switch off the compressor.
✽ ✽
NOTICE
The pressure gauge may show high-
er than actual reading when the
compressor is running. To get an
accurate tire reading, the compres-
sor needs to be turned off.CAUTION
When you use the Tire Mobility
Kit, the tire pressure sensors
and wheel may be stained by
sealant. Therefore, remove the
tire pressure sensors and wheel
stained by sealant and have
your vehicle inspected by an
authorized Kia dealer.
WARNING
Do not let the compressor run
for more than 10 minutes; other-
wise, the device may overheat
and be damaged.

What to do in an emergency
- To reduce the inflation pres-
sure:Press the button (9) on the
compressor.
CAUTION - Tire pressure
sensor
When you use the Tire Mobility
Kit with sealant not approved by
Kia, the tire pressure sensors
may be damaged by sealant. The
sealant on the tire pressure sen-
sor and wheel should be
removed when you replace the
tire with a new one and inspect
the tire pressure sensors at an
authorized dealer.

TIRES AND WHEELS
Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
Recommended cold tire infla-
tion pressures
All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold Tires” means the
vehicle has not been driven for at
least three hours or driven less than
1.6 km (1 mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure
refer to “Tires and wheels” in chapter
8.All specifications (sizes and pres-
sures) can be found on a label
attached to the driver’s side center
pillar.
WARNING - Tire underin-
flation
Inflate your tires consistent with
the instructions provided in this
manual. Severe underinflation
(70 kPa (10 psi) or more) can
lead to severe heat build-up,
causing blowouts, tread separa-
tion and other tire failures that
can result in the loss of vehicle
control. This risk is much higher
on hot days and when driving
for long periods at high speeds.

Maintenance
Underinflation also results in
excessive wear, poor handling and
reduced fuel economy. Wheel
deformation also is possible. Keep
your tire pressures at the proper
levels. If a tire frequently needs
refilling, have it checked by an
authorized Kia dealer.
Overinflation produces a harsh
ride, excessive wear at the center
of the tire tread, and a greater pos-
sibility of damage from road haz-
ards.
Warm tires normally exceed rec-
ommended cold tire pressures by
28 to 41 kPa (4 to 6 psi). Do not
release air from warm tires to
adjust the pressure or the tires will
be underinflated.
Be sure to reinstall the tire inflation
valve caps. Without the valve cap,
dirt or moisture could get into the
valve core and cause air leakage. If
a valve cap is missing, install a
new one as soon as possible.Tire pressure
Always observe the following:
Check tire pressure when the tires
are cold. (After vehicle has been
parked for at least three hours or
hasn't been driven more than 1.6
km (1 mile) since startup.)
Check the pressure of your spare
tire each time you check the pres-
sure of other tires.
Never overload your vehicle. Be
careful not to overload a vehicle
luggage rack if your vehicle is
equipped with one.
Checking tire inflation pres-
sure
Check your tires once a month or
more.
Also, check the tire pressure of the
spare tire.
How to check
Use a good quality gauge to check
tire pressure. You cannot tell if your
tires are properly inflated simply by
looking at them. Radial tires may
look properly inflated even when
they're underinflated.
Check the tire's inflation pressure
when the tires are cold. - "Cold"
means your vehicle has been sitting
for at least three hours or driven no
more than 1.6 km (1 mile).
WARNING - Tire Inflation
Overinflation or underinflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure. This
could result in loss of vehicle
control and potential injury.

Maintenance
44 7
Remove the valve cap from the tire
valve stem. Press the tire gauge firm-
ly onto the valve to get a pressure
measurement. If the cold tire inflation
pressure matches the recommended
pressure on the tire and loading
information label, no further adjust-
ment is necessary. If the pressure is
low, add air until you reach the rec-
ommended amount.
If you overfill the tire, release air by
pushing on the metal stem in the
center of the tire valve. Recheck the
tire pressure with the tire gauge. Be
sure to put the valve caps back on
the valve stems. They help prevent
leaks by keeping out dirt and mois-
ture. Inspect your tires frequently for
proper inflation as well as wear and
damage. Always use a tire pres-
sure gauge.
Tires with too much or too little
pressure wear unevenly causing
poor handling, loss of vehicle con-
trol, and sudden tire failure leading
to accidents, injuries, and even
death. The recommended cold tire
pressure for your vehicle can be
found in this manual and on the tire
label located on the driver's side
center pillar.
Remember to check the pressure
of your spare tire. Kia recommends
that you check the spare every
time you check the pressure of the
other tires on your vehicle.Tire rotation
To equalize tread wear, it is recom-
mended that the tires be rotated
every 12,000 km (7,500 miles) or
sooner if irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out-
of-balance wheels, severe braking or
severe cornering. Look for bumps or
bulges in the tread or side of tire.
Replace the tire if you find either of
these conditions. Replace the tire if
fabric or cord is visible. After rotation,
be sure to bring the front and rear tire
pressures to specification and check
lug nut tightness.
Refer to “Tires and wheels” in chap-
ter 8.

Maintenance
Tire traction
Tire traction can be reduced if you
drive on worn tires, tires that are
improperly inflated or on slippery
road surfaces. Tires should be
replaced when tread wear indicators
appear. Slow down whenever there
is rain, snow or ice on the road, to
reduce the possibility of losing con-
trol of the vehicle.
Tire maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease
tire wear. If you find a tire is worn
unevenly, have your dealer check the
wheel alignment.
When you have new tires installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tire life. Additionally, a tire should
always be rebalanced if it is removed
from the wheel.
Tire sidewall labeling
This information identifies and
describes the fundamental charac-
teristics of the tire and also provides
the tire identification number (TIN)
for safety standard certification. The
TIN can be used to identify the tire in
case of a recall.

CAUTION - Wheel
Wheels that do not meet Kia's
specifications may fit poorly
and result in damage to the
vehicle or unusual handling and
poor vehicle control.
