This display helps to save fuel.Use the gear display to save fuel. If you are driving in the correct gear, a dot
will be shown next to the gear display. If you are not in the correct gear, an
arrow will appear next to the gear display indicating whether you should
change up or down.Odometer or flexible service interval displayOdometer
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
Ve hi cle s wi th Service intervals dependent on time/distance travelled
already
have certain service intervals set. The intervals are calculated individually 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 Service
or brake fluid change, appear in the sticker on the door pillar or in the Main-
tenance 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]
km
or
[XXXX]
days
The service message will disappear approximately 20 seconds after the igni-
tion 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 pressing
the button on the steering wheel controls.
With the ignition on, you can check the current service message at any
moment 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.

charge. Never short the battery terminals. High-energy sparks can cause
injury.
•A highly explosive mixture of gases is released when the battery is
under charge. The batteries should be charged in a well-ventilated room
only.•Keep children away from acid and batteries.•Before working on the electrical system, you must switch off the
engine, the ignition and all consumers. The negative cable on the battery
must be disconnected. When a light bulb is changed, you need only switch
off the light.•Deactivate the anti-theft alarm by unlocking the vehicle before you
disconnect the battery! The alarm will otherwise be triggered.•When disconnecting the battery from the vehicle electrical system,
disconnect first the negative cable and then the positive cable.•Switch off all electrical consumers before reconnecting the battery.
Reconnect first the positive cable and then the negative cable. Never
reverse the polarity of the connections. This could cause an electrical fire.•Never charge a frozen battery, or one which has thawed. This could
result in explosions and chemical burns. Always replace a battery which
has frozen. A flat battery can freeze at temperatures around 0 °C.•Ensure that the vent hose is always connected to the battery.•Never use a defective battery. This could cause an explosion. Replace a
damaged battery immediately.Caution
•Never disconnect the battery if the ignition is switched on or if the engine
is running. This could damage the electrical system or electronic compo-
nents.•Do not expose the battery to direct sunlight over a long period of time, as
the intense ultraviolet radiation can damage the battery housing.
•If the vehicle is left standing in cold conditions for a long period, protect
the battery from freezing. If it freezes it will be damaged.Checking the electrolyte level
The electrolyte level should be checked regularly in high-
mileage vehicles, in hot countries and in older batteries.– Open the engine bonnet and the battery cover ⇒ in “Safety
instructions on working in the engine compartment” on
page 221 ⇒ in “Warnings on handling the battery” on
page 234.
– Check the colour display in the "magic eye" on the top of the battery.
– If there are air bubbles in the window, tap the window gently until they disperse.The position of the battery is shown in the corresponding engine compart-
ment diagram ⇒page 277.
The “magic eye” indicator, located on the top of the battery changes colour,
depending on the charge state and electrolyte level of the battery.
There are two different colours:•Black: correct charge status.•Transparent/clear yellow: the battery must be replaced. Contact a special-
ised workshop.
