Thanks again and sorry for bothering you.I read some parts of the User s Guide when I bought the car but concentrated on the part concerning the instrument pannel,mirrors,air condition,lights,trip computer....etc.if i shared in writing this subject it would be in English ,as if i m just copying,so it s useless not because i don t write Arabic but it s easier for me to use the English letters on the keyboardand i hate writing arabic in English letters,when i find somebody doing that i actually don t read what he wrote .
