1-Runflat tires do not come equipped with a spare wheel and tire. All Season tires are suitable for most weather conditions. Staggered tires indicate a difference in width from front to back. 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 performance 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.

2-Active Guard is not a substitute for the driver's own responsibility in maintaining safe control of the vehicle. Lane Keeping Assistant requires clearly definable lane markings that are not obscured by rain, snow, etc.
