Fig. 124 In the stowage compartment on the front passenger side: button for the Tyre Pressure Loss Indicator
The Tyre Pressure Loss Indicator uses data from the ABS sensors and other functions to check the speed of rotation and the rolling circumference of the individual wheels. Any change in the rolling circumference of one or more wheels is shown by the Tyre Pressure Loss Indicator in the instrument cluster.
Changes in the rolling circumference
The rolling circumference of a tyre can change:
In certain circumstances, the Tyre Pressure Loss Indicator
may become slow or may not display
anything, e.g. with a sporty driving style, in winter driving conditions, on unpaved
roads, or when driving with snow chains.
Calibrating the Tyre Pressure Loss Indicator
The Tyre Pressure Loss Indicator will have to be re-synchronised after changing the tyre pressure, or after changing one or more wheels. This also applies when wheels are swapped, e.g. from the front to the rear.
During normal vehicle operation, the system calibrates itself independently to the fitted tyres and the tyre pressures filled by the driver. The calibrated values are stored and monitored after a long journey at various speeds.
If the wheels are loaded more heavily than normal, e.g. if the vehicle is carrying heavy payload, the tyre pressure must be raised to the recommended full-load tyre pressure before synchronisation .
WARNING
A/C Evaporator Temperature Switch -E33
Function:
The A/C Evaporator Temperature Switch -E33- determines the
temperature between the evaporator cooling fans. It prevents the
possibility of ice building up between the evaporator cooling
fans because the current entry to the con ...
Single Wire Seal Assembly Tools
Assembly tools serve the purpose of allowing the single wire
seals to be slid without damage into terminal housing up to
stop, this achieves a complete seal between single wire and
