256 STARTING AND OPERATING WARNING! Overloading of your tires is dangerous. Overloading can cause tire failure, affect vehicle handling, and increase your stopping distance. Use tires of the recommended load capacity for your vehicle. Never overload them. TIRES - GENERAL INFORMATION Run Flat Tires This vehicle is equipped with run flat tires. Although the tires are designed with a "run flat" feature that allows the vehicle to be driven about 50 miles (80 km) at 55 mph (88 km/h), immediate service should be obtained. WARNING! Do not exceed 55 mph (88 km/h) if the "Tire Pressure Monitoring Telltale Light" is illuminated. Vehicle handling and braking may be reduced. You could have an accident and be severely or fatally injured. NOTE: The "run flat" feature eliminates the need for a spare tire or jack. This vehicle is not equipped with either a spare tire or jack.
