“ Comfort pressure Reduce speed “ warning
If the maximum speed of the preset comfort
pressure is exceeded and the tire pressure is
below a critical limit, a warning message appears
on the multi-function display.
Driving at excessive speeds when the comfort
pressure is active will destroy the tires.
f
Reduce speed to below the displayed
maximum speed.
f
Always inflate the tires to the standard tire
pressure when driving at higher speeds.
System learning
Tire Pressure Monitoring System begins to “learn”
the tires after a wheel change, wheel transmitter
replacement or update of the tire settings. During
this process, TPMS recognizes the wheels and
their locations.
The message “ No tire pressure monitoring
System is learning
” appears on the multi-
function display.
The wheel learning process takes place
exclusively when the vehicle is being driven
(vehicle speed above 16 mph (25 km/h)).
TPMS requires a certain amount of time to learn
the wheels. During this time, the current tire
pressures are not available on the multi-function
display:
– The tire pressure warning light stays on until all
wheels have been learned.
– Lines (-.-) appear on the display of the “ TPMS ”
function.
– The required pressures for cold tires (68 °F/
20 °C) are shown under “
Fill info
” in the
“ TPMS ” main menu.
Position and pressure information is displayed as
soon as TPMS has assigned the wheels
recognized as belonging to the vehicle to the
correct wheel positions.
f
Check the tire pressure for all wheels under
“ Fill info ”.
f
Correct the tire pressure to the required
pressure if necessary (differential pressure
value “0.0” ).
Tire pressure warnings
The tire pressure warning light on the instrument
panel and a corresponding message on the multi-
function display warn about loss of pressure in two
stages (yellow and red), depending on the amount
of pressure loss.
Driving at excessive
speeds when the
comfort pressure is
