Lexus IS 350C 2014 Pds Manual page 4

As part of the PDS road test, the vehicle must be driven over a rough road surface or over Bott Dots in order
to check for squeeks and rattles. If a rough surface is not available for this road test, Bott Dots should be installed
on the dealership property where vehicles can be safely driven 5 to 10 mph. (See Bott Dots installation
instructions below, as recommended and provided by TMC Quality Division.) Bott Dots are commonly available
at industrial supply outlets.
