Maintenance
All specifications (sizes and pressures) can be found on a label attached to the vehicle.
TIP
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).
Checking tire inflation pressure
僅 Remove the valve cap from the tire valve stem. Press the tire gauge firmly onto the
valve to get a pressure measurement. If the pressure is low, add air until you reach the
recommended amount.
僅 If you overfill the tire, release air by pushing on the metal stem in the center of the tire
valve. Be sure to put the valve caps back on the valve stems.
WARNING
僅 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.
僅 Severe underinflation (70 kPa (10 psi) or more) can lead to severe heat build-up, caus-
ing blowouts, tread separation and other tire failures that can result in the loss of vehicle
control leading to severe injury or death. This risk is much higher on hot days and when
driving for long periods at high speeds.
僅 Inspect your tires frequently for proper inflation as well as wear and damage. Always
use a tire pressure gauge.
僅 Tires with too much or too little pressure wear unevenly causing poor handling, loss of
vehicle control, 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.
僅 Worn tires can cause accidents. Replace tires that are worn, show uneven wear, or are
damaged.
僅 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.
CAUTION
僅 Underinflation also results in excessive wear, poor handling and reduced energy
economy. Wheel deformation also is possible. Keep your tire pressures at the proper lev-
els. If a tire frequently needs refilling, have the system checked by a professional work-
shop. Kia recommends to visit an authorized Kia dealer/service partner.
僅 Overinflation produces a harsh ride, excessive wear at the center of the tire tread, and a
greater possibility of damage from road hazards.
僅 Warm tires normally exceed recommended 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 underin-
flated.
僅 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.
僅 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 (one mile) since startup.)
- Check the pressure of your spare tire each time you check the pressure of other tires.
