Gr II (Speed Control II): Notes

INTRODUCTION:

GRII was introduced for the first time on the E38 740L GR II is a speed control system for vehicles not equipped with EML. It is similar in operation to the former system (FGR) found on older models. It offers improved control electronics to ensure that the set speed is reached and maintained without the sensation of fast acceleration or deviations of more than 1 MPH from the set speed.

The GR II offers the following advantages:

Fatigue-free driving over long distances with a set speed.
The constant travel speed results in lower fuel consumption.
By setting a speed, speed limits are observed automatically.

Like most of the other systems in the E38/E39, the GR II utilizes digital signal processing. This eliminates the amount of wiring required to achieve system operation and improves the reliability of cruise control operation.

The driver's request for cruise control functions is activated by the button pads of the MFL.

An ON / OFF main switch ensures that the cruise control system is not inadvertently engaged while driving the vehicle.
