KEYS AND DOORS NOTICE D When the snow tires must be repaired, have them repaired by Lexus dealer or authorized tire dealer. The tire pressure sensor will be affected by the installation or removal of snow tires. D When the snow tires must be replaced, replace the grommets for air pressure sensors as well. D Do not attempt to use a tire chain on the compact spare tire, as it may result in damage to the vehicle as well as the tire. D When driving with chains installed, be sure to drive carefully. Slow down before entering the curves to avoid losing control of the vehicle. Otherwise an accident may occur. REPLACING WHEELS As you might have difficulty in locating a flat or deflated tire, a tire pressure warning system should be provided on the tires of this vehicle. When replacing the wheels, be sure to install air pressure sensors on the wheels. There are 2 ways to set up the air pressure sensors. a. Remove the sensor from the old wheel and install it to the new wheel. b. Use a new wheel and sensor. You have to register an ID code for a new sensor. Up to 2 sets of codes can be registered. As one ID for the originally installed sensor is registered at "MAIN" of the selector switch, use the "2nd" position to register an ID for the new sensor. You do not need to re-register the ID code for any other replacements. For the use of the originally installed tires, put the selector switch at "MAIN" and for the use of tires purchased later, put the switch at "2nd". For the sensor selector switch, see page 224. INFORMATION If the chains are installed, the air pressure warning system may not operate properly. CAUTION D Do not exceed 50 km/h (30 mph) or the chain manufacturer's recommended speed limit, whichever is lower. D Drive carefully avoiding bumps, holes, and sharp turns, which may cause the vehicle to bounce. D Avoid sharp turns or locked-wheel braking, as use of chains may adversely affect vehicle handling. 311 SC430 through December 2001 Production
