Instruments and controls107On Uplevel display select Info Menu
by pressing p on steering wheel.
Press P to select Remaining Oil
Life page.
Remaining oil life duration is indicated
in percentage.
Reset On Midlevel display press SET/CLR
on turn signal lever for several
seconds to reset. The ignition must be
switched on but engine not running.
On Uplevel display press > on
steering wheel to open the subfolder. Select Reset and confirm by pressing
9 for several seconds. The ignition
must be switched on but engine not
running.
The system must be reset every time
the engine oil is changed to allow
proper functionality. Seek the
assistance of a workshop.
Next service A message appears in the Driver
Information Centre, when
maintenance of the vehicle is
required. Have maintenance workcarried out by a workshop within one week or 300 miles, whichever occursfirst.

Control indicators The control indicators described are
not present in all vehicles. The
description applies to all instrument
versions. Depending on the
equipment, the position of the control
indicators may vary. When the
ignition is switched on, most control
indicators will illuminate briefly as a functionality test.

Have the cause of the fault
remedied immediately by a
workshop.
Antilock brake system
(ABS)
u illuminates yellow.
Illuminates for a few seconds after the ignition is switched on. The system is
ready for operation when the control
indicator extinguishes.
If the control indicator does not go out after a few seconds, or if it illuminates while driving, there is a fault in the
ABS. The brake system remains
operational but without ABS
regulation.

Gear shifting R or S with the number of a higher or
lower gear is indicated, when up- or
downshifting is recommended for fuel
saving reasons.

A fault in the system is present.
Continued driving is possible. Driving
stability, however, may deterioratedepending on road surface
conditions.
Driving and operating167A warning message appears when
exhaust filter is full. Start cleaning
process as soon as possible.
A warning message also appears
when exhaust filter has reached the
maximum filling level. Start cleaning
process immediately to avoid
damage to the engine.
Activate self-cleaning process
To activate cleaning process,
continue driving, keep engine speed
above 2000 rpm. Shift down if
necessary. Exhaust filter cleaning is
then started.
Cleaning process is completed more
quickly at high engine speeds and
loads.
Keep on driving until self-cleaning
operation is complete and the display
message disappears.Caution
If possible, do not interrupt
cleaning process. Drive until
cleaning is completed to avoid the need for service or repair by a
workshop.
Cleaning process not possible
If cleaning is not possible for anyreason, control indicator Z
illuminates and a warning message
appears in the Driver Information
Centre. Engine power may be
reduced. Seek the assistance of a
workshop immediately.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.
Caution
Fuel grades other than those listed on pages 3 218, 3 286 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
Vehicle care257Uplevel display:
Select the Tyre pressure page under
the Info Menu in the Driver
Information Centre 3 114.
System status and pressure warnings
are displayed by a message
indicating the corresponding tyre in
the Driver Information Centre.
The system considers the tyre
temperature for the warnings.
Temperature dependency 3 255.
A detected low tyre pressure
condition is indicated by the control
indicator w 3 111.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 294.
If w flashes for 60-90 seconds then
illuminates continuously, there is a
fault in the system. Consult a
workshop.
After inflating, some driving may be
required to update the tyre pressure
values in the Driver Information
Centre. During this time w may
illuminate.
If w illuminates at lower temperatures
and extinguishes after driving, this
could be an indicator for approaching
a low tyre pressure condition. Check
tyre pressure.
Vehicle messages 3 122.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w
illuminates continuously.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. The tyre pressure
monitoring system is not operational
for these tyres. Control indicator w
illuminates. For the further three
tyres, the system remains
operational.
The use of commercially-available liquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.
Operating electronic devices or being close to facilities using similar wave
frequencies could disrupt the tyre
pressure monitoring system.
Each time the tyres are replaced, tyre
pressure monitoring system sensors
must be dismounted and serviced.
For the screwed sensor, replace
valve core and sealing ring. For the
clipped sensor, replace complete
valve stem.
