become quite hot. Therefore, do not touch them while the engine is running or
immediately after turning the engine off.
When washing the vehicle, be careful not to touch the exhaust pipes and rear
bumper exhaust diffusers until they have cooled sufficiently, as touching hot exhaust
pipes and diffusers can cause burns.
