Concept
The system can be used to set a speed limit, for instance to prevent the vehicle from exceeding speed limits.
General information
The system can limit the speed, starting at a value of 20 mph/30 km/h. The vehicle can be driven at any speed below the set speed limit.
Overview
Buttons on the steering wheel
System on/off.
Store current speed.
Speed Limit Assist: take over suggested speed manually.
Rocker switch:
Changing the speed limit.
Operation
Switching on
Press the button on the steering
wheel.
The current speed is accepted as the speed limit.
If the system is switched on while the vehicle is stationary or driving at low speeds, 20 mph/30 km/h is set as the speed limit.
The marking in the speedometer is set to the respective speed.
When the speed limit is switched on, DSC Dynamic Stability Control and COMFORT driving mode may be switched on as well.
Switching off
Press the button on the steering
wheel.
The system switches off automatically in the following situations, for example:
The displays go out.
Interrupting
If the reverse gear is engaged or at idle, the system is interrupted when rolling backwards.
Changing the speed limit
Press the rocker switch up or down repeatedly until the desired speed limit is set.
If the set speed limit is reached or unintentionally exceeded, such as when driving downhill, the vehicle is not actively braked.
If the speed limit is set during a trip to a value below the current speed, the vehicle coasts until it drops to the set speed limit.
The current speed can also be stored by pressing a button:
Press the button on the steering
wheel.
Exceeding the speed limit
If the vehicle speed exceeds the set speed limit, a warning is issued.
The speed limit can be exceeded intentionally.
There is no warning in this case.
Press the accelerator pedal all the way down to intentionally exceed the set speed limit.
When the vehicle speed drops below the set speed limit, the limit is automatically reactivated.
Warning when the speed limit is exceeded
Visual warning
If the speed limit is exceeded:
the indicator
light in the instrument cluster flashes
while the vehicle speed is greater than
the set speed limit.
Acoustic warning
Displays in the instrument cluster
Display in the speedometer
Indicator light
Data list / active test
1. DATA LIST
HINT:
Using the DATA LIST displayed on the intelligent tester,
you can read the value of the switch, sensor, actuator,
etc. without parts removal. Reading the DATA LIST as
the first step of troubleshooting is one way to shorten the
labor time.
Connect the intelligent tester to ...
Warning function
If you leave the lane
If you leave the lane and if a lane marking has
been detected, the steering wheel vibrates in accordance
with the steering wheel vibration setting.
If the turn signal is switched on before a lane
change, a warning is not issued.
