part of the powertrain.

3.4.3. "Peripheral devices" means any energy consuming, converting, storing or supplying devices, where the energy is not directly or indirectly used for the purpose of vehicle propulsion but which are essential to the operation of the powertrain and are therefore considered to be part of the powertrain.
              3.4.4. "Drivetrain" means the connected elements of the powertrain for transmission of the mechanical energy between the propulsion energy converter(s) and the wheels.

              3.4.5. "Manual transmission" means a transmission where gears can only be shifted by action of the driver.

              3.5. General

              3.5.1. "Criteria emissions" means those emission compounds for which limits are set in this Regulation.

              3.5.2. (Reserved)

              3.5.3. (Reserved)

              3.5.4. (Reserved)

              3.5.5. (Reserved)

              3.5.6. "Cycle energy demand" means the calculated positive energy required by the vehicle to drive the prescribed cycle.

              3.5.7. "Defeat device" means any element of design which senses temperature, vehicle speed, engine speed (RPM), transmission gear, manifold vacuum or any other parameter for the purpose of activating, modulating, delaying or deactivating the operation of any part of the emission control system, that reduces the effectiveness of the emission control system under conditions which may reasonably be expected to be encountered in normal vehicle operation and use.

              3.5.8. "Driver-selectable mode" means a distinct driver-selectable condition which could affect emissions, or fuel and/or energy consumption.

              3.5.9. "Predominant mode" for the purpose of this Regulation means a single driver-selectable mode that is always selected when the vehicle is switched on, regardless of the driver-selectable mode in operation when the vehicle was previously shut down, and which cannot be redefined to another mode. After the vehicle is switched on, the predominant mode can only be switched to another driver-selectable mode by an intentional action of the driver.

              3.5.10. "Reference conditions (with regards to calculating mass emissions)" means the conditions upon which gas densities are based, namely 101.325 kPa and 273.15 K (0 °C).

              3.5.11. "Exhaust emissions" means the emission of gaseous, solid and liquid compounds from the tailpipe.

              3.5.12. "Configurable start mode" for the purpose of this Regulation means a driver-selectable mode that can be set by the driver as a mode which is automatically selected when the vehicle is switched on. After the vehicle is switched on, the configurable start mode can only be switched to another mode by an intentional action of the driver.

              3.6. PM/PN

              The term "particle" is conventionally used for the matter being characterised (measured) in the airborne phase (suspended matter), and the term "particulate" for the deposited matter.

              3.6.1. "Particle number emissions" (PN) means the total number of solid particles emitted from the vehicle exhaust quantified according to the dilution, sampling and measurement methods as specified in this Regulation.

              3.6.2. "Particulate matter
