WARNING
The tire replacement indicator is not a
substitute for regular tire checks, includ-
ing tire pressure checks. For additional
information, refer to “Changing wheels
and tires” in the “Do-it-yourself” section of
this manual. Many factors including tire
inflation, alignment, driving habits and
road conditions affect tire wear and when
tires should be replaced. Setting the tire
replacement indicator for a certain drivingdistance does not mean your tires will last
that long. Use the tire replacement indica-
tor as a guide only and always perform
regular tire checks. Failure to perform
regular tire checks, including tire pressure
checks could result in tire failure. Serious
vehicle damage could occur and may lead
to a collision, which could result in serious
personal injury or death.
