Parc fermé following the first qualifying pratice session
All cars which complete a flying lap during the first qualifying practice session will be stopped in the weighing area and weighed. Some cars, selected at random, will be detained for further checks and released as soon as possible after the end of the session. Whilst the cars are being detained three appropriate members from each Team will be permitted in the FIA’s central parc fermé at any one time for the purpose of :
- fitting cooling devices;
- fitting a fuel breather;
- checking tyre pressures;
- connecting a jump battery under the supervision of the FIA;
- downloading data by physical connection to the car under the supervision of the FIA;
- fitting water heaters;
- engine oil may be drained;
- changing tyres before the car is pushed back to the Team’s garage;
- carrying out any work required by the FIA Technical Delegate;
- removing, refitting or checking on board cameras, timing transponders and any associated equipment.

Once any such work has been carried out the Team personnel must leave the central parc fermé immediately. No other work of any kind will be permitted at this time unless deemed absolutely necessary by the FIA Technical Delegate.

Parc fermé following the second qualifying practice session
General :
The parc fermé procedure has two purposes. First, to check the cars for general conformity with the Technical and Sporting Regulations and, secondly, to ensure that in each case the car which is scrutineered, qualified and raced is one and the same.
Every car which took part in the second qualifying session, or was intended for use during the session (in the event of a driver failing to leave the pits), will be required in parc fermé. Any car which failed to leave the pits during the session must be taken to the parc fermé immediately. If a car is damaged during the session the FIA Technical Delegate may make alternative arrangements according to the level of damage and any other circumstances he deems relevant. Accordingly, each car will be deemed to be in parc fermé from the time at which the pit exit light turns green for the start of its qualifying run on Saturday until the green lights are illuminated at the start of the formation lap which immediately precedes the first start of the race.

Between these times Teams may carry out the following work :
- cooling devices may be fitted;
- changes to improve the drivers comfort. In this context anything other than addition or removal of padding (or similar material) and adjustment of mirrors and pedals may only be carried out with the specific permission of the FIA Technical Delegate;
- a fuel breather may be fitted;
- bodywork (excluding radiators) may be removed and / or cleaned;
- cosmetic changes may be made to the bodywork;
- any part of the car may be cleaned;
- any parts which are removed from the car in order to carry out any work specifically permitted below must remain close to it and, at all times, be visible to the scrutineer assigned to the relevant car;
- fluids used for replenishment must conform to the same specification as the original fluid;
- on board cameras, timing transponders and any associated equipment may be removed, refitted or checked.

For safety reasons, no fuel may be added to or removed from the car between the second qualifying session and the race. This will avoid the danger that in a search for extra performance during qualifying, the car could be assembled in a manner which, while optimum for qualifying with a minimal fuel load, might be unsuitable or even dangerous at the start of the race.

Immediately after entering the pits :
All cars which take part in the second qualifying practice session will be stopped in the weighing area, weighed and then held in the central parc fermé until the session is finished. The weight of the car at this time (without driver) will be used as a reference in the event of a driver using another race car and for comparison with the weight of the car immediately before the pit lane opens for the race.

Whilst the cars are being held we will allow three appropriate members from each Team (not three per car) to be in the FIA’s central parc fermé at any one time for the purpose of:
- checking tyre pressures;
- connecting a jump battery under the supervision of the FIA;
- downloading data by physical connection to the car under the supervision of the FIA;
- fitting water heaters;
- engine oil may be drained;
- changing tyres before the car is pushed back to the Team’s garage. These, or any other tyres, may be used when the car is returned to the central parc fermé the same evening and back to the Team’s garage on Sunday morning. The wheels and tyres used for qualifying will be marked and / or sealed by the scrutineers before being released to the Team;
- carrying out any work required by the FIA Technical Delegate.

Once any such work has been carried out the Team personnel must leave the central parc fermé immediately.

No other work of any kind will be permitted at this time unless deemed absolutely necessary by the FIA Technical Delegate.

Saturday afternoon :
Once the session has finished, and all preliminary checks have been carried out by the FIA, the cars held in the central parc fermé will be released simultaneously and Teams will be permitted to push them back to their garages. Cars will remain under parc fermé conditions throughout. From this point, and until 18.30, Teams will be permitted to carry out the following work under supervision of the scrutineers :
- wheels may be removed;
- removal of any parts genuinely necessary to carry out essential safety checks;
- removal of spark plugs to carry out an internal engine inspection and cylinder compression checks;
- engines may be started (an external fuel pressurising system may be used if necessary but only fuel on board the car may be used for running the engine);
- with the exception of fuel, fluids with a specific gravity less than 1.1 may be drained and/or replenished;
- draining and / or addition of compressed gases;
- heating devices may be fitted;
- on board electrical units may be freely accessed via a physical connection to the car;
- repair of bona fide accident damage;

No other work will be permitted during this time unless the FIA Technical Delegate is satisfied that it is absolutely necessary and has specifically authorised it. At some time before 18.30 all cars used during the qualifying session (or which were intended for use but failed to leave the pits) must be taken back to the central parc fermé, with all parts used for qualifying re-fitted (other than wheels and tyres, which if they are not fitted to the car, must be taken separately), where they will remain secure until the following day. Whilst cars are in the central parc fermé they may be covered and fitted with devices to keep them warm, no Team personnel will be permitted there unless specifically authorised by the FIA Technical Delegate.
