ENGINE 272 in MODEL 221 with CODE (219) Distronic (DTR) up to Model Year 8
ENGINE 273 in MODEL 221 with CODE (219) Distronic (DTR) up to Model Year 8
Variable Speed Limiter activated
The Variable Speed Limiter (also known as the Limiter) is an additional function of DISTRONIC and is integrated in the ESP control unit (N47-5).
Using the Variable Speed Limiter, the driver set a maximum speed for himself ranging from 30 km/h up to the maximum vehicle speed. If the vehicle approaches the set maximum speed, the set maximum speed is maintained by engine intervention and if necessary by intervention by the brake system.
The CC [TPM] switch can be moved up or down (S40/4) to increase or decrease the maximum speed in 1 km/h or 10 km/h increments (two settings).
Function requirements
By pressing the CC [TPM] switch, a switchover must place from the DISTRONIC position to the Variable Speed Limiter position. The LIM indicator lamp in the CC [TPM] switch is illuminated.
By pressing the CC [TPM] switch, a switchover to the Variable Speed Limiter takes place and DISTRONIC is deactivated simultaneously.
Activation
Pulling or moving the CC [TPM] switch up or down will activate the Variable Speed Limiter.
- By up the CC [TPM] switch, the Variable Speed Limiter is activated with the last saved target speed provided that a target speed has already been saved since the last engine start (set). If no target speed is stored, the current vehicle speed is set as the target speed.
- By moving the CC [TPM] switch up or down, the Variable Speed Limiter is activated with the current vehicle speed as the target speed.
If the Variable Speed Limiter is activated, the segments in the speedometer rim are lit from the start of the scale through to the set maximum speed. The set maximum speed is marked with an orange-colored triangle.
Deactivation
The Variable Speed Limiter is deactivated when:
- The CC [TPM] switch is pushed in
- By pressing the CC [TPM] switch, a switchover to the DISTRONIC position takes place (LIM indicator lamp off)
- Kickdown (accelerator pedal depressed >90 %) is activated and the vehicle speed is less than 20 km/h away from the set maximum speed
The Variable Speed Limiter and Permanent Speed Limiter have the sales designation "SPEEDTRONIC".
