The system’s availability is electronically governed – it can be used at any time in practice and qualifying (unless a driver is on wet-weather tyres), but during the race can only be activated when a driver is less than one second behind another car at pre-determined points on the track. The system is then deactivated once the driver brakes.
ECU – electronic control unit, or the brain of the engine which controls all of its functions Engine mapping – the setting which dictates how an engine behaves. Drivers can adjust the settings during a race, often to alter strategy
Flags – Marshals at various points around the circuit are issued with a number of standard flags, all used to communicate vital messages to the drivers as they race around the track. A special display in each driver’s cockpit – known as a GPS marshalling system – also lights up with the relevant flag colour, as the driver passes the affected section of track.
Chequered Flag – Indicates to drivers that the session has ended. During practice and qualifying sessions it is waved at the allotted time, during the race it is shown first to the winner and then to every car that crosses the line behind him.
Yellow Flag – Indicates danger, such as a stranded car, ahead. A single waved yellow flag warns drivers to slow down, while two waved yellow flags at the same post means that drivers must slow down and be prepared to stop if necessary. Overtaking is prohibited.

Traction Control – similar to a road car, a system which detects if a rear wheel is spinning and transfers more power to the one that has grip. This system was banned in F1 cars from the 2008 season onwards
Tire Warmer – An electric blanket that is wrapped around the tyre, before they are fitted to the car, in order to keep them as close to optimum temperature as possible
Warm-up – what drivers use the green flag lap to bring the components of their car up to operating temperature, often weaving to warm tires and braking heavily to warm the brakes
