    1-Non-run-flat tires come equipped with a Mobility Kit. Driving over rough or damaged road surfaces, as well as debris, curbs and other obstacles, can cause serious damage to wheels, tires and suspension parts. This is more likely to occur with low-profile tires, which provide less cushioning between the wheel and the road. Be careful to avoid road hazards and reduce your speed, especially if your vehicle is equipped with low-profile tires. Performance tires are not recommended for driving in ice and snow conditions.

    2-Cruise control is not a substitute for the driver's own responsibility in adjusting speed and otherwise controlling the vehicle. After evaluating the road, traffic and visibility conditions, the driver must decide whether and how the system is to be used.

    3-Active Guard is not a substitute for the driver's own responsibility in maintaining safe control of the vehicle.
