Initialization/Operation

Initialization/Operation





The system must be initialized when the tire inflation pressures are changed or when the wheels/tires are replaced.
The RPA switch (1) in the center console switching center must be pressed to start initialization (as follows on the next page).





With KL15 on, press the RPA switch until the RPA indicator light in the Instrument Cluster illuminates in yellow.
After a a short drive (approximately 13 minutes), from a vehicle speed > 10 mph, the system learns the new wheel speed sensor reference values and the RPA indicator light (yellow) goes out.
When an inflation pressure loss is determined, the RPA indicator light illuminates in red. The driver is informed of a RPA system failure by the yellow illuminated RPA indicator light.
