Most/all cars come with a service book which lays out what needs to be done every so many ,000 miles. Can't be that difficult to have a look and see when your aircon needs attention?
Yes - I have checked the owners manual (since coming home this evening) and it doesnt mention any specific time schedule for re-filling the air conditioning.
Doesn't seem that responsible when taking the car out onto the public highway and you injure an innocent passerby.
I doubt very much if any passer by has ever been or ever will be injured because a car didnt have fully functioning air-con.
I am properly maintaining my car as demonstrated by the fact that I take it for annual services at the required times to a proper Toyota dealership and that I accepted the recommendation today to have the brake fluid renewed.
Quite specifically, the only thing I am querying is whether the air con needs refilling on the basis of them saying this year (and not last year or any of the previous 3 years) that it is something they recommend doing routinely every two years.
Good thread, lets have the next imbecilic comment, please

Let's not.
