    On my Renault Master there is a button marked Kg & when I press it the speedo display lights up'Kg'. The manual says:>

    Load position
    When the vehicle is driven laden, press the switch on the dashboard. The indicator light will
    light up Kg on the instrument panel. Load mode is deselected every time the engine is switched off. It will be necessary to select it again. Load mode may be used to equal
    effect in both automatic andmanual modes.

    BUT what does it do :Confused::Confused: Tried it on & off but can't tell any differnece.

    maybe alters the power output via the ecu.

    same as chipping but only temporary.

    Probably an input into the braking/stability system to give it advance notice that the vehicle is loaded so adjusts the appropriate settings.

    Depending on the weight of your MH - if it is close to gross weight - it probably should be pushed every time you start the engine

    Found this in http://j46pays.renault-trucks.com/J46PAYS/web/ImageServlet?imageCode=125029&codeSite=J46CORPO&etat=1

    The new Master is also provided with additional equipment as standard features or
    on option depending on the version and country:
    - ESP specially designed for LCVs. It incorporates a load sensing unit that adjusts
    brake power to the payload

    Another enhancement relative to the previous generation is adaptive ESP for the new
    Master. This system, specially designed for light commercial vehicles, includes a load
    detection unit which adapts system response to vehicle load to ensure the driver of
    sound vehicle behaviour in all conditions of use.

    Could the control that you are talking about be the input to the ESP system.

    Got this reply from Renault:
    'I can confirm that the KG button on your Renault Master motor home is used to alter the gear box settings when you add additional weight to your vehicle. Therefore when you add any additional weight to the vehicle you must use the KG button.'

    I can understand that it could be used to change how my gearbox performs as it is an automatic, but the handbook says
    'Load mode may be used to equal effect in both automatic andmanual modes.'
    I don't see how it would change any setting on a manual gearbox :RollEyes:

    Tried it on & off & I can't tell any noticable difference does anybody else with a Renault use it?

    a long shot, but there may be a reduction gear on the input or output shaft of the gearbox.

    similar to the old fashioned overdrive gear on manual boxes but reducing gearing slightly instead of increasing it.

    this would also work on an autobox.

    you could check by noting revs to speedo in a given gear...say 3rd...Stop, then flick the switch on and set off again checking revs against speed in 3rd again.


    only thing i can think of.:thumb:
