The HOLD function is deactivated automatically if:
• you accelerate and the transmission is in position D or R.
• you shift the transmission to position P.
• you apply the brakes again with a certain amount of pressure until HOLD disappears from the multifunction display.
• you activate DISTRONIC PLUS.

WARNING
Never get out of the vehicle when the HOLD function is activated.
The HOLD function must never be operated or deactivated by a passenger or from outside the vehicle.
The HOLD function does not replace the parking brake and must not be used for parking.
The braking effect of the HOLD function is canceled and the vehicle could roll away if:
• the HOLD function is deactivated by depressing the accelerator pedal or the brake pedal.
• there is a malfunction in the system or an interruption in the power supply, e.g. battery failure.
• the electrical system in the engine compartment, the battery or the fuses are tampered with.
• the battery is disconnected.
If you leave the vehicle or park it, deactivate the HOLD function and secure the vehicle against rolling away.

You will see a warning message in the multifunction display if the HOLD function is activated and:
• the driver's door is open and the driver's seat belt is unfastened.
• the engine is switched off.
• the hood is opened.

Shift to 'P'

Move the selector lever to P to prevent the vehicle from rolling away.
The HOLD function is deactivated. The warning message in the multifunction display disappears.

A horn will also sound at regular intervals if the HOLD function is activated and you:
• switch the engine off, open the driver's door and take off your seat belt
• open the hood

The sounding of the horn alerts you to the fact that the vehicle has been parked while the HOLD function is still activated. If you attempt to lock the vehicle, the tone becomes louder.

The vehicle is not locked until the HOLD function is deactivated.

If the engine has been switched off, it cannot be started again until the HOLD function has been deactivated.

If there is a malfunction in the system or power supply while the HOLD function is activated, the Brake immediately message is shown in the multifunction display.

Immediately depress the brake firmly until the warning message in the multifunction display goes out.

You can also shift the transmission to position P. This deactivates the HOLD function.
