Tire Pressure Control Indicator, Performing Basic Setting

Tire Pressure Monitoring System, Performing Basic Setting

NOTE: Basic setting of Tire Pressure Monitoring Display Indicator Lamp K220 should always only be performed, "after" tire inflation pressure values have first been corrected to the proper values.
If no pressure loss and no tire damage is detected after a tire pressure warning, the erroneous warning can be eliminated by a basic setting.

Tire Pressure Monitory System display is a component of ABS Control Module -J104- software.

ABS Control Module compares speed and rolling circumference of individual wheels with help of ABS sensors. If rolling circumference of a wheel changes, this is displayed via tire pressure control indicator. Rolling circumference of tire may be change if:
- Tire inflation pressure is too low.
- Tires have structural damage.
- Vehicle is loaded on one side.
- Wheels of one axle are loaded higher (e.g. when towing trailer or driving uphill and downhill).
- Snow chains are installed.
- Spare wheel is installed.
- One wheel per axle was replaced.






Tire Pressure Monitoring Display Indicator Lamp K220 has a yellow indicator light in instrument cluster -arrow-.
- "BLINKING LIGHT" means that no "INITIAL BASIC SETTING" was performed yet.
- "STEADY LIGHT" , in conjunction with warning buzzer, means "WARNING", a loss of pressure was detected, check tire inflation pressures, perform system basic setting.

Performing "INITIAL" basic setting
- Switch ignition on.






- Simultaneously press the ESP -1- button and SET -2- button in the center console for longer than 2 seconds.
If ESP is not installed, press the button for ASR.

Beginning of basic setting is confirm by a notifying tone.

On next new ignition start, warning does not appear.





Performing basic setting
- Switch ignition on.
- After changing tire pressures or changing one or more tires, tire pressure display SET button, item -2- in illustration, must be pressed until a confirmation tone is heard.
Warning will no longer appear next time engine is switched on.
