dure yourself.

The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance. Refer
to the “Maintenance Plan” for further information.

10,000 miles (16,000 km), 12 months or 350 hours of engine
run time, whichever comes first. The 350 hours of engine run
or idle time is generally only a concern for fleet customers.

Tread Wear Indicators
Tread wear indicators are in the original equipment tires to
help you in determining when your tires should be replaced.Tire Tread These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes a 1/16 of an inch (1.6 mm). When the tread is worn
to the tread wear indicators, the tire should be replaced.
Refer to “Replacement Tires” in this section for further infor
-
mation.
Life Of Tire
The service life of a tire is dependent upon varying factors
including, but not limited to:
• Driving style
• Tire pressure - Improper cold tire inflation pressures can cause uneven wear patterns to develop across the tire
tread. These abnormal wear patterns will reduce tread life,
resulting in the need for earlier tire replacement
• Distance driven
• Performance tires, tires with a speed rating of V or higher, and Summer tires typically have a reduced tread life. Rota -
tion of these tires per the vehicle scheduled maintenance is
highly recommended
