The following information relates to the tire grading system developed by the
National Highway Traffic Safety
Administration (NHTSA), which grades tires by tread wear, traction and
temperature performance. Tires that have
deep tread, and winter tires, are exempt from these marking requirements.
NOTE: Easily adjust your climate preferences, such as turning on the seat
heater or changing the cabin temperature,
hands-free by using voice commands (see Voice Commands).
NOTE: For one-touch access to seat heaters and defrosters, you can add
these controls to My Apps. See
