Multi-Purpose Display and Instruments Setting tire sealant/sealing set
fInflate tires according to the displayed
pressure differences.
A warning appears on the multi-purpose display if
the speed limit of 50 mph (80 km/h) is exceeded.
The reminder SPARE WHEEL/SEALING SET
OPERATION? appears each time the ignition is
switched on.
For information on spare wheel/sealing set opera-
tion: Please see the chapter “NOTE ON SPARE
WHEEL/SEALING SET OPERATION” on Page 140.
Warning!
Risk of accident, resulting in serious
personal injury or death if a tire repaired with
tire sealant is in use.
fAvoid hard acceleration and high cornering
speeds.
fDo not exceed maximum speed of 50 mph
(80 km/h).
fPlease observe the safety and operating
instructions on the tire compressor.
fUse tires repaired with sealant only over short
distances.
For information on handling and filling the
sealant: Please see the chapter “USING TIRE SEALANT” on Page 296.
Note on spare wheel/sealing set operationEach time the ignition is switched on,
the reminder SPARE WHEEL/SEALING SET
OPERATION? appears for approx. 10 seconds if a
spare wheel type (spare wheel, collapsible spare
wheel or sealing set) has been set.

3.Confirm selection.
The display automatically returns to the TYRE
PRESSURE sub-menu (filling information). 1.Select YES or NO:
- YES if a spare wheel, collapsible spare wheel
or tire sealant is still being used.
- NO if the spare wheel, collapsible spare
wheel or tire sealant has been removed.
2.Confirm selection.
The selected item is then accepted.
The current settings are displayed if NO is

Note on operation
The reminder SPARE WHEEL/SEALING SET
OPERATION? goes out automatically after approx.
10 seconds if no selection is made during this
time. The original selection “YES” is then
maintained.In the event of faults, Tire Pressure Monitoring
cannot monitor the tire pressure. A distinction is
made between partial monitoring and inactive
system.
In the case of partial monitoring, the tire pressure
warning light on the speedometer flashes about
60 seconds and lights up thereafter permanently.
No message is output on the multi-purpose
display.
If Tire Pressure Monitoring is not active, the tire
pressure warning light on the speedometer
flashes about 60 seconds and lights up thereafter
permanently. A corresponding message is output
on the multi-purpose display.
The warning light goes out as soon as all faults
have been remedied.
Tire Pressure Monitoring switches to partial
monitoring if:
– there are up to two wheel transmitters not
present or faulty (e.g. a spare wheel or collap-
sible spare wheel is fitted that does not have a
wheel transmitter).
In the event of partial monitoring, the value “_” is
displayed in the sub-menu TYRE PRESSURE (filling
information) at the position of the faulty or missing
wheel transmitter.
Tire Pressure Monitoring is not active in the
following cases:
– Tire Pressure Monitoring is faulty,– at least three wheel transmitters for Tire
Pressure Monitoring are faulty or not present,
– temporarily after changing a wheel,
– too many wheel transmitters have been
detected,
– there is external interference by other radio
sources, e.g. wireless headphones,
– tire temperatures are too high.
fFor information on messages on the multi-
purpose display:
Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on Page 149.
Notes on tire pressurePressure increase as the result of tempera-
ture increase
In accordance with physical principles, the tire
pressure changes as the temperature changes.
The tire pressure increases or decreases by
around 1.5 psi (0.1 bar) for every 18 °F (10 °C)
change in temperature.
Tire pressure specifications
The tire pressure must match the prescribed value
(required pressure).
You can find information on the tire pressure for
cold tires 68 °F (20 °C):

Multi-Purpose Display and Instruments – in the sub-menu TYRE PRESSURE (filling infor-
mation):
as a required pressure for each axle if Tire
Pressure Monitoring has not yet been taught
the corresponding values,
– in the front left door aperture for each wheel,
– in the Technical Data chapter in this Owner’s
Manual: Please see the chapter “TIRE
PRESSURES, COLD (68 °F/20 °C)” on
Page 354.
If Tire Pressure Monitoring has been taught the
corresponding values, the deviations from the
required pressure are shown in the sub-menu
TYRE PRESSURE (filling information) indepen-
dently of the tire temperature. The correct tire
pressure adjustment can be made for a wheel on
the basis of this display information even if the
tires are warm.
Insufficient tire filling pressure can cause tires to
overheat when driving and thus be damaged –
even invisibly.
Hidden tire damage is not eliminated by subse-
quently correcting the tire pressure.
fFor this reason, always make sure that the tire
pressure is correct.
fFor further information on maintenance and
care of tires and wheels:
Please see the chapter “TIRES/WHEELS” on
Page 281.
Switching off passenger compart-
ment monitoring on the multi-
purpose displayThe passenger compartment monitoring system
can be temporarily deactivated in the ALARM sub-
menu.
When the doors are locked again, the ultrasound
passenger compartment monitoring system is
activated once more.

topic can be found in a separate chapter:
