monitor automatically recognizes new wheels

or new sensors. As long as a clear allocation

of the tire pressure values to the individual

wheels is not possible, the Tire Pressure

instead of the tire pressure display. The tire

pressures are already being monitored.

If a spare wheel/emergency spare wheel

is mounted, the system may continue to

show the tire pressure of the wheel that has

been removed for a few minutes. If this

occurs, note that the value displayed for

the position where the spare tire is

mounted is not the same as the spare

wheel/emergency spare wheel's current

tire pressure.

significant pressure loss on one or more tires,

a warning message is shown in the

multifunction display. Awarning tone also

are displayed for the correctpositions.

Restarting the tire pressure monitor

When you restart the tire pressure monitor,

all existing warning messages are deleted and

the warning lamps go out. The monitor uses

the currently set tire pressures as the

reference values for monitoring. In most

cases, the tire pressure monitoring system

recognizes the new reference values

automatically.

However, you can also define reference

values manually as described here:

X

Set the tire pressure to the value

recommended for the corresponding

driving situation on the vehicle's Tire and

Loading Information placard on the driver's

side B-pillar(Y page 297).

Additional tire pressure values for driving

at high speeds or with heavy loads can be
