Tire Pressure Monitor Lamp
Details & Technology
Pressure-monitoring sensors on each wheel transmit radio signals to a central control unit.
On vehicles with pixel matrix instrument cluster (Code JK3) an automatic warning is displayed
if the pressure in any tire falls below a set minimum value. The critical tire is indicated in the
display. On vehicles with standard instrument cluster, a warning light comes on in the event
of a pressure loss of approx. 25% at one or more tires.
Sensing is not carried out for the spare wheel.
Benefits & Arguments
• Enhanced safety
• Lower fuel consumption
• Reduced tire wear
Underinflation results in increased tire wear and higher fuel consumption. Early detection of
pressure losses therefore extends tire life and reduces running costs. Correct inflation
pressures also optimise steering and braking performance.
