To immobilise the vehicle
With the vehicle stationary, to apply the parking brake whether the engine is running or off, pull on control A.
The application of the park-ing brake is confi rmed by :
- the lighting of the warning lamp on control A and of warning lamp P on the instrument panel,
- the display of a message “park-ing brake applied” on the multi-function display.
When the driver’s door is opened with the engine running, a beep is heard and a message displayed if the parking brake has not been applied.
MAXIMUM APPLICATION
If necessary, you can utilise maxi-mum application of the parking brake. It is obtained by means of a long pull on control A, until you see the message “parking brake applied” and a beep is heard.
Maximum application is indispensable :
- in the case of a vehicle towing a caravan or a trailer, if the au-tomatic functions are activated but you are applying the parking brake manually,
- when the gradient you are parked on is variable in its effect (e.g. on a ferry, in a lorry, during towing).
Note :
- In the case of towing, a loaded vehicle or parking on a gradient, turn the front wheels towards the pavement and engage a gear when you park.
- After a maximum application, the release time will be longer.
PARTICULAR SITUATIONS
In certain situations (starting the engine ...), the parking brake can automatically alter its force. This is normal operation.
To advance your vehicle a few centimetres without starting the engine, but with the ignition on, press on the brake pedal and re-lease the parking brake by pull-ing then releasing control A. The full release of the parking brake is confi rmed by the extinction of warning lamp P (red) on the instru-ment panel and the display of a message “parking brake released” on the multifunction display.
If the parking brake malfunctionswhile applied or if the battery runs fl at, an emergency release is always possible (see paragraph “Emergency unlocking”).
