Failure to do so may result in the vehicle being unable to be driven safely, and
may cause death or serious injury.

Do not drive in excess of the speed limit specified for the tire chains being
used, or 50 km/h (30 mph), whichever is lower.

Avoid driving on bumpy road surfaces or over potholes.

Avoid sudden acceleration, abrupt steering, sudden braking and shifting oper-

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 (except vehicles with 18-inch tires)
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.
