Using liquid sealants can damage
the tire valves and tire pressure
monitor sensors in the run-flat

by the vehicle warranty. Do not
use liquid sealants in run-flat

Summer Tires

This vehicle may come with high
performance summer tires. These
tires have a special tread and
compound that are optimized for
maximum dry and wet road
performance. This special tread and
compound will have decreased
performance in cold climates, and
on ice and snow. We recommend
installing winter tires on the vehicle
if frequent driving at temperatures
below approximately 5°C (40°F) or
on ice or snow covered roads is
expected. See Winter Tires on
page 10-41.
