Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Influence on the dynamics in conjunction with a navigation system
If the Active Cruise Control is coupled with a navigation system, this may have an influence on the dynamics. (Only possible in combination of CCC with the Professional navigation system option 609.)
Navigation systems provide additional information, such as the course of the road and the road category.
The road category is split up as follows:
- Motorways and well finished fast roads
(faster acceleration)
- Main roads and highways
(average acceleration)
- Urban driving
(reduced acceleration)
On motorways and well finished fast roads, Active Cruise Control is expected to be highly dynamic. In other words, faster acceleration if the driving mode changes from following a car ahead to clear road ahead. The set speed is adjusted quickly.
On main roads and highways, Active Cruise Control is expected to be averagely dynamic. In other words, comfortable acceleration if the driving mode changes from following a car ahead to clear road ahead. The set speed is adjusted with an average acceleration behavior.
During urban driving, a reserved dynamic is expected of the Active Cruise Control. In other words, reduced acceleration behavior if the driving mode changes from following a car ahead to clear road ahead. The set speed is adjusted moderately.
The often difficult traffic situations during urban driving make reduced acceleration behavior necessary.
In addition, the number of bends on the road ahead is analyzed and the dynamic of the Active Cruise Control adjusted accordingly.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
