Remote start (ERS)*

Updated 7/23/2018

Remote start (ERS – Engine Remote Start) means that the car's engine can be started remotely using the remote control key or the PCC key. This is so that the passenger compartment can be warmed up/cooled down before departure.

The climate control system and audio system start with the same settings that were in use when the car was parked.

An ERS-started engine is activated for a maximum of 15 minutes, then it is switched off. After two ERS-activations the engine must be started in the normal way before ERS can be re-used.

The ERS option is available on most cars with automatic gearbox.

Note

The service life of the remote control key's battery is affected by the ERS function. In the event of frequent use of ERS the battery should therefore be changed once per year, see Remote control key/PCC - replacing the battery.

Note

Follow local/national rules/regulations on idling.

Warning

To remote-start the engine, the following criteria must be met:

  • The car must be supervised.
  • There must be no people or animals inside the car.
  • The car must not be parked in a closed, unventilated area - the exhaust gases may seriously injure humans and animals.
