The left-hand counter in the display registers the total amount of distance
covered by the vehicle. The right-hand counter registers the short journeys. The last digit indicates
steps of 100 metres. The trip recorder counter may be reset by holding
down the reset button for a few seconds.
Service interval display
Vehicles with
Service intervals dependent on time/distance travelled al-
ready have certain service intervals set. The intervals are calculated individ-
ually in vehicles with LongLife service.
The service interval display only indicates the dates of services that include
engine oil change. The dates of all other services, such as Inspection Serv-
ice or brake fluid change, appear in the sticker on the door pillar or in the
Maintenance Programme.
A Service pre-warning will appear in the odometer if a service is due soon. A
“spanner” symbol appears and the display “km” with the distance that can
be driven until the next service appointment is due. The display will change
after approximately 10 seconds. A “clock symbol” appears and the number
of days until the service appointment should be carried out. The following
message is shown in the instrument panel display*: Service in
[XXXX]
kmor
[XXXX]
days
The service message will disappear approximately 20 seconds after the ig-
nition is switched on or the engine is running. The normal display can be
resumed by briefly pressing the reset button on the trip counter or by press-
ing the OK
button on the steering wheel controls.
With the ignition on, you can check the current service message at any mo-
ment in the Vehicle status menu or turning the reset button to access the
service display.
An overdue service is indicated by a minus sign in front of the mileage or
day information. 

Coolant level* / temperature  (red)
The warning lamp lights up if the coolant temperature is too
high or if the coolant level is too low.
There is a fault if:
● The warning symbol does not go out again after a few seconds.
● The warning lamp lights up or flashes while the vehicle is moving, and
three acoustic warning signals ⇒ 
are emitted.
This means that either the coolant level is too low or the coolant tempera-
ture is too high.
Coolant temperature too high
The instrument panel displays the following message 1)
: CHECK COOLANT IN-
STRUCTION MANUAL ⇒  page 224.
First look at the coolant temperature gauge. The coolant temperature is too
high if the needle is over the warning area on the dial. Stop the vehicle,
switch the engine off and wait for it to cool down. Check the coolant level.
If the coolant level is correct, the overheating may be caused by a malfunc-
tion of the radiator fan. Check the radiator fan fuse and have it replaced if
necessary ⇒ page 250.
If the warning lamp lights up again after driving on for a short distance,
stop the vehicle and switch the engine off . Contact an Authorised Service
Centre or a specialised workshop.
Coolant level too low
The instrument panel displays the following message 1)
: STOP CHECK COOL-
ANT INSTRUCTION MANUAL.
First look at the coolant temperature gauge. If the needle is in the normal
range, top up with coolant at the earliest opportunity ⇒
