CHASSIS Regulations regarding the use of tire chains vary according to location or type of road. Always check local regulations before installing chains. D When driving with chains installed, be sure to drive carefully. Slow down before entering curves to avoid losing control of the vehicle. Otherwise an accident may occur. D Vehicles with electronically modulated air suspension: When installing the tire chains, be sure to turn off the height control and stop the engine. Otherwise, the vehicle height may change in the automatic leveling function, resulting in an unexpected accident. For details, see page 445. If the chains are installed, the tire pressure warning system may not operate properly. See "Tire pressure warning system" on page 462. NOTICE If the wrong combination of tire and chain is used, the chains could damage the vehicle body. Chain installation Install the chains on the front tires as tightly as possible.
