Remote control key

The remote control key locks and unlocks the doors, tailgate and fuel filler flap. The remote control key needs to be inside the car for it to be started.

Remote control key1 or key tag (Key Tag)*.

The remote control key is not physically used when starting since the car is equipped with support for keyless starting (Passive Start) as standard. You simply need to have the key in the front part of the passenger compartment.

For cars equipped with keyless locking and unlocking (Passive Entry)* the key can be anywhere in the car to start the car. In this case, a slightly smaller, lighter key tag (Key Tag) is also supplied.

The remote control keys can be linked to different driver profiles to save personal preferences in the car.

 Warning

The remote control key contains a button cell battery. Keep new and used batteries out of the reach of children. If someone swallows a battery it may cause serious injury.

If damage is discovered, e.g. if the battery cover cannot be closed properly, then the product should not be used. Keep defective products out of the reach of children.

 Warning

If anyone is left in the car, make sure the power windows and panoramic roof* are de-energised by always taking the remote control key with you when you leave the car.

 Note

Be aware of the risk of locking the remote control key in the car.

  • A remote control key or key tag left in the car will be deactivated when the car is locked and the alarm is armed using another valid key. The "Double lock" function is also deactivated. The key left behind is reactivated when the car is unlocked.

Button-less key (Key Tag)*

The key tag provided with the keyless locking and unlocking function works in the same way as the standard remote control key as regards keyless starting and locking and unlocking. The key is waterproof to a depth of approx. 10 metres (30 feet) for up to 60 minutes. It has no detachable key blade and the battery cannot be replaced.

Interference

Remote control key functions for keyless starting and keyless locking and unlocking* can be disrupted by electromagnetic fields and screening.

 Note

Avoid storing the remote control key close to metal objects or electronic apparatus, e.g. mobile phones, tablets, laptops or chargers - preferably no closer than 10-15 cm (4-6 inches).

If there is still interference - use the remote control key's detachable key blade to unlock and then place the key in the backup reader in the storage compartment to disarm the car and allow the car to be started.

 Note

When the remote control key is positioned in the backup reader in the storage compartment, make sure that there are no car keys, metal objects or electronic apparatus nearby (e.g. mobile phones, tablets, laptops or chargers). Several car keys close to one another in the storage compartment may cause interference with each other.
