Restarting the tire pressure monitor
When you restart the tire pressure monitor, allexisting warning messages are deleted and thewarning lamps go out. The monitor uses the cur-rently set tire pressures as the reference valuesfor monitoring. In most cases, the tire pressuremonitor will automatically detect the new refer-ence values after you have changed the tirepressure. However, you can also set referencevalues manually as described here. The tirepressure monitor then monitors the new tirepressure values.
XSet the tire pressure to the value recommen-ded for the corresponding driving situation onthe Tire and Loading Information placard onthe driver's side B-pillar (Ypage 293).
You can find more tire pressure values forvarious operating conditions in the tire pres-sure table inside the fuel filler flap(Ypage 141).
XMake sure that the tire pressure is correct onall four wheels.
