The cruise control with braking function is included as part of the G30's standard equipment. The system is also known as "Dynamic Cruise Control" (DCC). Dynamic Cruise Control (DCC) supports the driver on roads with less traffic by keeping the speed constant irrespective of rolling resistances (incline, downhill driving and vehicle load). In spite of the support, the driver remains responsible for control of the vehicle. It is possible to override the DCC function at any time by braking or accelerating the vehicle.
Operation
The driver has the option of adjusting the set speed in small or large increments, which is then set and maintained by the system by controlling the drive and brakes. It can be changed using the left- hand switch block on the multifunction steering wheel (MFL). The speed is increased or reduced by 1 mph by tapping the rocker switch. Each time the rocker button is pressed beyond the pressure point, the speed increases or reduces by 5 mph. The DCC steadily maintains a selected speed from approximately 20 mph (30 km/h).
The set speed is indicated in the instrument cluster in the familiar way; by a mark that moves round the speed reading. Notes are added to the displays in the instrument cluster, if necessary.
If the vehicle's own deceleration is not sufficient to maintain the preset speed, the brake is activated accordingly.
If ECO PRO or SPORT mode is activated, cruise control is also set to a fuel-efficient or sporty driving style. Due to the fuel-efficient driving style in ECO PRO driving mode, in some situations the vehicle's speed may exceed or drop below the set speed, for example on downhill gradients or inclines.
