Tire Monitoring System: Service and Repair
The Tire Pressure Monitoring begins to "learn" the wheels after a wheel change, wheel transmitter replacement or update of the tire settings. During this
process, the Tire Pressure Monitoring recognizes the tires and their locations. The on-board computer displays the message "TPM is learning,
monitoring not act.".
The Tire Pressure Monitoring requires a certain amount of time to learn the wheels. During this time, the current tire pressures are not available on the
The tire pressure warning light remains lit until all wheels have been learned.
The display of the tire pressure function of the on-board computer shows lines.
The required pressures for cold tires at 68 °F (20 °C) are indicated in the Info pressure display in the tire pressure menu.
Position and pressure information is displayed as soon as the Tire Pressure Monitoring has assigned the wheels identified as belonging to the vehicle to
the correct wheel positions. The wheel learning process takes place exclusively when the vehicle is being driven (vehicle speed above 25 km/h (16 mph)
Check the tire pressure for all wheels on the "Info pressure" display.
Correct the tire pressure to the required pressure if necessary.
Changing a wheel and replacing tires
New wheels must be fitted with radio transmitters for the Tire Pressure Monitoring. Before tires are changed, the battery charge state of the wheel
transmitters should be checked.
Switch the ignition off when changing a wheel. The tire settings on the on-board computer must be updated after changing a wheel. If the tire
settings are not updated, the message "Wheel change? Input new TPM settings!" is displayed on the on-board computer.
Update the on-board computer settings when the vehicle is stationary the next time.
Your vehicle has also been equipped with a Tire Pressure Monitoring (TPM) malfunction indicator when the system is not operating properly.
The TPM malfunction indicator is combined with a low tire pressure telltale.
When the system detects a malfunction, the telltale will flash for approx. one minute and then remain continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended.
TPM malfuntions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the
TPM from functioning properly. Always check the TPM malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that
the replacement or alternate tires and wheels allow the TPM to continue to function properly.
The warning light in the speedometer lights up:
When a loss in pressure has been detected.
When learning newly mounted wheels/wheel sensors, as long as the vehicle's own wheels have not yet been recognized.
In the event of a defect in Tire Pressure Monitoring or a temporary fault, the warning light in the speedometer flashes for approx. one minute and then
remains continuously illuminated.
The tire pressure warning light in the instrument panel goes out only when the cause of the fault has been rectified.
Monitoring of the other wheels is continued if there is a fault in one or two wheel transmitters.
The tire pressure warning light lights up.
The message "TPM partial monitoring" is displayed on the on-board computer.
No tire pressures are displayed on the onboard computer for wheels with faulty wheel transmitters.
