NOTICE TO OWNERS WITH 20 INCH WHEELS AND TIRES
When equipped with 20 inch wheels and tires the vehicle is designed for
on-road use only and not off-road use.
Note:When first driving the vehicle after it has been parked for a period
of time, you may experience a temporary ride disturbance. This is a
characteristic of the tires and should be no reason for concern. The
condition should correct itself within 5-15 miles (8-25 km) of driving. If
the disturbance persists, have the tires serviced by an authorized dealer.
Correct tire pressure is important to payload and proper ride and
handling attributes. Check your vehicle’s Safety Compliance Certification
Label or Tire Label for the proper tire pressure levels.
