G
Warning!
Follow recommended tire inflation
pressures.
Do not overinflate tires. Overinflated
tires can adversely affect handling and
ride comfort, wear unevenly, increase
stopping distance, and result in sudden
deflation (blowout) because they are
more likely to become punctured or
damaged by road debris, potholes etc.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and fuel econ

omy, and are more likely to fail from being
overheated.
Do not overload the tires by exceeding
the specified load limit as indicated on
the Tire and Loading Information placard
on the driver’s door B
pillar. Overload

ing the tires can overheat them, possibly
causing a blowout. Overloading the tires
can also result in handling or steering
problems, or brake failure.
G
Warning!
After changing a tire, contact a smart
center to make sure that the bolts holding
the wheel to the car are tight enough.
Otherwise, the wheels could come off.
Each bolt should be tightened to a torque
of 81 lb
ft (110 Nm).
