BMW 7 Series: Introduction
Keyless Vehicle Access
Using Comfort Access, the customer can unlock and open the vehicle without active use of the ID transmitter.
Access to the vehicle can be gained from any point. It is important that the ID transmitter be located in the vehicle's immediate vicinity (approximately 5 feet). It is sufficient to have the ID transmitter somewhere on your person.
Comfort Access was first introduced on the E65 (03/2002). The system was then gradually introduced on different BMW models. There were the 1 Series, 3 Series, 5 Series, 6 Series, X5 and X6.
The F01/F02 will have Comfort Access from the start of series production in 09/2008. Comfort Access can be ordered as an option.
The benefits of Comfort Access are:
- High level of convenience when unlocking and locking the vehicle
- Convenient and fast access to the vehicle
- Simple engine start/stop procedure
- Maximum comfort for the driver
- No more annoying hunting for keys.
The Comfort Access in the F01/F02 is based on predecessor systems and is adapted to the F01/F02. However, the entire function is now located in the Car Access System 4. For this reason, there is no separate control unit for Comfort Access in the F01/F02, in contrast to previous systems.
The vehicle is unlocked when you place your hand into the handle recess on the outside of the door and opened when you pull the door handle.
You can lock the vehicle again by subsequently pressing on the sensitive surface of the outside door handle.
For vehicles fitted with Soft Close Automatic, the Soft Close Automatic drive fully closes the vehicle door. You can then lock the vehicle again by subsequently pressing on the sensitive surface of the outside door handle.
The ID transmitter must be located in the vehicle interior in order for the engine to be started. The engine can now be started by pressing the START-STOP button and the vehicle is ready to be driven.
NOTE: In vehicles with automatic transmission, the brake pedal must be depressed in order for the engine to be started.
In vehicles with manual transmission, the clutch pedal must be depressed in order for the engine to be started.
