Remote control
Description
- The remote control allows you to lock and unlock the vehicle remotely.
You can perform the following functions:
- Locking and unlocking the vehicle
- Unlocking the tailgate
Locking and unlocking of the vehicle are indicated by the turn signals. In addition, the interior lights switch on or off automatically if their control is set to the door contact switch position.
The transmitter with the battery is located in the ring of the remote control key.
The receiver is located in the passenger compartment. The maximum operating range of the remote control depends on various factors.
As the battery power decreases, the range of the remote control is reduced.
The key of the remote control has a folding bit that can be used to lock and unlock the vehicle manually as well as to start the engine.
If you need to replace a key or if the receiver needs to be repaired or replaced, a specialist workshop must initialize the system. Only then can the remote control be used again.
The remote control meets all approval criteria and has been approved by the Federal Approvals Office for Telecommunications of the Federal Republic of Germany. All components are marked in accordance with the currently applicable directives. The approval granted serves as the basis for approval in other countries.
Note
- The remote control is automatically deactivated when the ignition is switched on.
- System operation may be disrupted by transmitters operating on the same frequency range (e.g. mobile phone, television transmitter) located near the vehicle.
