The manufacturer is unable to guarantee
that all tire punctures can be repaired with
the tire repair kit, in particular cuts or
perforations larger than approximately
0.16 in (4 mm) or away from the tire's tread.
The manufacturer is not liable for damage
sustained through improper use of the tire
repair kit.>Drive to the nearest authorized smart cen

ter, to have the damaged tire replaced.
>Contact an authorized smart center as soon
as possible to obtain a new filler hose

>Bring used tire sealant materials to an
authorized smart center for proper dispos

al.
>Replace your tire sealant container every
4 years. Replacement containers are avail

able at any authorized smart center.
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).
