TIRE PRESSURE MONITORING
INSTRUMENTATION
Front and rear
tire pressure
monitoring,
wireless
Details and Technology
Pressure monitoring sensors on each wheel transmit radio signals to a central control unit. On vehicles
with pixel matrix instrument cluster, 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 approximately 25% at one or more
tires. Sensing is not carried out for the spare wheel.
Benefits and Arguments
• Enhanced safety
• Reduced fuel consumption
• Reduced tire wear
Under inflation results in increased tire wear and higher fuel consumption. Therefore, early detection of
pressure losses extends tire life and reduces running costs. Correct inflation pressure also optimizes
steering and braking performance.
Remarks
Tire pressure monitoring is standard on Passenger Vans and 2500 Cargo Vans.
