Dear Sir Volvo Bus Corporation's (manufacturer of the relevant chassis) response to Mr: Brown'$ Regulation 28 Report dated December 13,2018 [sic] (the "Report") Before commenting further we would like to take this opportunity to extend our sincerest condolences to Mr Wrightson's family and those affected by this tragic accident: We have read and considered the Report_ We have also consulted with appropriate specialist technical expert teams both in the UK and Sweden, thank ou for your forbearance during this period as we are sure you will understand, it is important for Us that our response is well founded. It is our understanding that you are specifically seeking a response to your concern that the lack of information contained in the vehicle manual may lead to a lack of understanding or uncertainty, more specifically in respect of the correct use of the automated manual gearbox during a descent and the claim that use of the automated manual gearbox may exacerbate brake fade on a descent such as Alp D'Huez. We believe that it is primarily these concerns that we are asked to comment_ As a preliminary point we would like to point out that there are a number of systems on the vehicle that can assist a driver in these circumstances. It is important to ensure that all are working correctly and used in the correct manner; of particular importance are the retarders_ Having investigated your concerns thoroughly we do not support a general statement that the use of automatic gear mode is likely to exacerbate brake fade in long descents. It is true that the automatic mode and manual mode both have characteristics which can be different to each other. However these differences can be both positive and negative depending on the characteristic and the circumstance: On balance we do not feel that the differences are sufficient to issue a recommendation in the vehicle manual in favour of one gearbox mode over the other: The correct use of the retarder is much more important than the selection of manual or automatic mode on the gearbox when driving down hills and this is highlighted on page 56 of the current manual which states "Use the retarder function when driving down hills and for slow braking" wwwvolvoco.uk Volvo Group UK Ltd: Telephone Fax Registration No. Registered Office Wedgnock Lane 01926 401777 01926 490991 2190944 Wedgnock Lane Warwick England Warwick CV34 SYA Cv34 5YA Tony Tony long long
