WARNING
The tire replacement indicator is not a
substitute for regular tire checks, in-
cluding tire pressure checks. For addi-
tional information, refer to “Changing
wheels and tires” in the “Do-it-yourself ”
section of this manual. Many factors in-
cluding tire inflation, alignment, driving
habits and road conditions affect tire
wear and when tires should be re-
placed. Setting the tire replacement in-
dicator for a certain driving distancedoes not mean your tires will last that
long. Use the tire replacement indicator
as a guide only and always perform
regular tire checks. Failure to perform
regular tire checks, including tire pres-
sure 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.
