262 STARTING AND OPERATING WARNING! (Continued) • Failure to equip your vehicle with tires having adequate speed capability can result in sudden tire failure and loss of vehicle control. CAUTION! Damage to the vehicle may result if tire chains are used. SNOW TIRES Some areas of the country require the use of snow tires during Winter. Standard tires are of the all-season type and satisfy this requirement as indicated by the M+S designation on the tire sidewall. If you need snow tires, select tires equivalent in size and type to the original equipment tires. Use snow tires only in sets of four; failure to do so may adversely affect the safety and handling of your vehicle. Snow tires generally have lower speed ratings than what was originally equipped with your vehicle and should not be operated at sustained speeds over 75 mph (120 km/h). CAUTION! Replacing original tires with tires of a different size may result in false speedometer and odometer readings. TIRE CHAINS Due to limited clearance, tire chains are not recommended.
