●Park the vehicle and move the shift lever to P without setting the parking 
brake. The parking brake may freeze up,  preventing it from being released. If 
the vehicle is parked without setting the parking brake, make sure to block the
wheels. 
Failure to do so may be dangerous because it may cause the vehicle to move 
unexpectedly, possibly leading to an accident.
●If the vehicle is parked without setting  the parking brake, confirm that the shift 
lever cannot be moved out of P*.
*: The shift lever will be locked if it is atte mpted to be shifted from P to any other posi- 
tion without depressing the brake pedal. If the shift lever can be shifted from P,
there may be a problem with the shift lock system. Have the vehicle inspected by
your authorized Lexus reta iler or Lexus authorized repairer, or any reliable 
repairer immediately.
Except vehicles with 18-inch tires 
Use the correct tire chain size when mounting the tire chains.  
Chain size is regulated for each tire size.
