Ciallaíonn ‘modh luasmhoillithe saor-rothlaithe feithicle’córas oibriúcháin lenar féidir ualach friotaíochta bóthair a chinneadh ar bhealach cruinn in-athdhéanta agus socrú cruinn raoin rollaigh a dhéanamh.
"Vehicle coastdown mode" means a system of operation enabling an accurate and repeatable determination of road load and an accurate dynamometer setting.

Is é an t-údarás freagrach a thabharfaidh formheas do mhodh luasmhoillithe saor-rothlaithe na feithicle, agus déanfar a úsáid a thaifeadadh.
The vehicle coastdown mode shall be approved and its use shall be recorded by the responsible authority.

Má tá feithicil feistithe le modh luasmhoillithe saor-rothlaithe feithicle, beidh sí oibrithe le linn chinneadh an ualaigh friotaíochta bóthair agus ar an raon rollach araon.
If a vehicle is equipped with a vehicle coastdown mode, it shall be engaged both during road load determination and on the chassis dynamometer.

Mura féidir cinneadh na socruithe dinimiméadair na critéir a thuairiscítear i míreanna 8.1.3. nó 8.2.3. den iarscríbhinn seo a chomhlíonadh de bharr fhórsaí neamh-intáirgthe, beidh an fheithicil feistithe le modh luasmhoillithe saor-rothlaithe feithicle.
If the determination of dynamometer settings cannot meet the criteria described in paragraphs 8.1.3. or 8.2.3. of this annex due to non-reproducible forces, the vehicle shall be equipped with a vehicle coastdown mode.

Mura féidir leis an gcinneadh maidir leis na socruithe dinimiméadair na critéir a thuairiscítear i mír 8.1.3. den iarscríbhinn seo a chomhlíonadh de bharr fhórsaí neamh-intáirgthe, beidh an fheithicil feistithe le modh luasmhoillithe saor-rothlaithe feithicle.
If the determination of dynamometer settings cannot meet the criteria described in paragraph 8.1.3. of this annex due to non-reproducible forces, the vehicle shall be equipped with a vehicle coastdown mode.

Mura ndéanann an fheithicil luasmhoilliú saor-rothlaithe ar bhealach in-athdhéanta agus nach bhfuil modh luasmhoillithe saor-rothlaithe feithicle de réir mhír 4.2.1.8.5. den iarscríbhinn seo indéanta, ríomhfar na comhéifeachtaí, f0, f1 agus f2 sa chothromóid ualaigh friotaíochta bóthair ag úsáid na gcothromóidí i mír 8.2.4.1.1. den iarscríbhinn seo.
If the vehicle does not coast down in a repeatable manner and a vehicle coastdown mode according to paragraph 4.2.1.8.5. of this annex is not feasible, the coefficients f0, f1 and f2 in the road load equation shall be calculated using the equations in paragraph 8.2.4.1.1. of this annex.

Má thástáiltear an fheithicil tástála ar dhinimiméadar ceithre roth in oibríocht dhá roth, féadfaidh na rothaí ar an acastóir neamhthiomána rothlú le linn na tástála ar choinníoll go dtacaíonn modh oibriúcháin dhinimiméadar na feithicle agus mód luasmhoillithe saor-rothlaithe feithicle leis an mbealach oibríochta sin.
If the test vehicle is tested on a 4WD dynamometer in 2WD operation the wheels on the non-powered axle may rotate during the test, provided that the vehicle dynamometer operation mode and vehicle coastdown mode support this way of operation.
