TIRE PRESSURE CONTROL INDICATOR, PERFORMING BASIC SETTINGNOTE:
- 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.
