NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tires from Lexus dealers or legitimate tire
retailers.
This is because the removal and attachment of snow tires affects the operation of
the tire pressure warning valves and transmitters.
■Fitting tire chains (vehicles with front and rear tires of the same size except for
the vehicles with LDH and 19 inch tires)
The tire pressure warning valves and transmitters may not function correctly when
tire chains are fitted.
■When standing the windshield wipers up
Raise the wipers in line with the windshield. (→P. 2 8 6 )
Failure to do so may result in damage to the wipers and/or the hood.
