As exhaust gases cause the exhaust pipes to become quite hot, do not touch the
exhaust pipes while the engine is running or immediately after the engine is turned off.
When washing the vehicle, be careful not to touch the exhaust pipes until they have
cooled sufficiently, as touching hot exhaust pipes can cause burns.
■Precaution regarding the rear bumper with Blind Spot Monitor (if equipped)
If the paint of the rear bumper is chipped or scratched, the system may malfunction. If
this occurs, consult your Lexus dealer.
