Division 6.1 In cases where a vehicle is provided with a spare unit, it shall be one of the following:

A standard spare unit in the same size as the tyres actually fitted to the vehicle.

A temporary-use spare unit of a type suitable for use on the vehicle, however, vehicles of categories other than M₁ or N₁ shall not be equipped or fitted with a temporary-use spare unit.

1. 6.1.2.1.

   If specific precautions have to be taken in order to fit a temporary-use spare unit to the vehicle (e.g. temporary-use spare unit is only to be fitted on the front axle and therefore a front standard unit must first be fitted on the rear axle in order to address a malfunction of a rear standard unit) this shall be stated clearly in the vehicle owner’s handbook and compliance with the appropriate aspects of paragraph 2.3 of this Annex shall be verified.
