If the coolant is within the specified range, the increased temperature may
be caused by an operating problem at the coolant fan. Check the fuse for
the coolant fan, replace it if necessary
⇒page 260, “Replacing fuses”.
Do not continue driving if the warning light does not go off although the
fluid is at the correct level and also the fuse of the fan is in proper order.
Contact a specialist garage to obtain assistance.
Please also refer to the additional instructions ⇒page 226, “Replenishing

COOLANT! OWNER'S MANUAL)
WARNING
•If you must stop for technical reasons, then park the vehicle at
a safe distance from the traffic and switch off the engine and switch
on the hazard warning light system ⇒page 60.
•Take care when opening the co olant expansion bottle. If the
engine is hot, the cooling system is pressurized - risk of scalding!
It is best to allow the engine to cool down before removing the cap.
•Do not touch the coolant fan! The coolant fan may switch on
automatically even if the ignition is off.

3 peeps sound as an additional warning signal.
Do not continue your journey if for some reason it is not possible under
the conditions prevailing to top up with oil. Keep the engine switched off
and obtain professional assistance from a specialist garage, otherwise it
could lead to severe engine damage.
Do not drive any further if the warning light remains on even if the oil is
at the correct level. Do not run the engine not at idling speed either.
Contact the nearest specialist garage to obtain professional assistance.
The following text will be displayed in the information display*:
STOP! OIL PRESS. STOP MOTOR! SERVICE MANUAL (STOP! OIL
PRESSURE STOP ENGINE! OWNER'S MANUAL)
lights up yellow* (quantity of oil too low)
If the warning light lights up yellow, there is not the correct quantity of oil
in the engine. Check as soon as possible the oil level or top up
⇒ page 223 with engine oil.
A peep sounds as an additional warning signal.
The following text will be displayed in the information display*: CHECK OIL LEVEL
The warning light will go out if the bonnet is left open for more than 30

WARNING
•If you must stop for technical reasons, then park the vehicle at
a safe distance from the traffic and switch off the engine and switch
on the hazard warning light system ⇒page 60.
•The red oil pressure light is not an oil level indicator! One
should therefore check the oil level at regular intervals, preferably
after every refueling stop.

Inspecting and Replenishing223
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
The warning light in the instrument cluster will indicate whether the oil
level is too low
⇒page 33, “Engine oil ”. In this case, check the oil level
as soon as possible. Top up with an appropriate quantity of oil.
WARNING
Read and observe the warning notes ⇒page 219, “Working in the
engine compartment” before working in the engine compartment.
Caution
•The oil level must on no account extend beyond the range . Danger
of damaging the catalytic converter.
•Do not continue your journey if for some reason it is not possible
under the conditions prevailing to top up with oil. Switch the engine off
and obtain professional assistance from a specialist garage, otherwise it
could lead to severe engine damage.
Replenishing engine oil
– Inspect the oil level ⇒page 222.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres ⇒page 221, “Engine oil specifications”.
– Inspect the oil level ⇒page 222.
– Carefully screw on the cap of the filler opening and push the dipstick in fully.
WARNING
•Avoid dripping oil onto hot parts of the engine when topping up
will oil - a risk of fire!
•Read and observe the warning notes ⇒page 219, “Working in
the engine compartment” before working in the engine compart-
ment.
For the sake of the environment
The oil level must on no account be above the range ⇒page 222,
fig. 171 . Oil will otherwise be drawn in through the crankcase ventilation
and may pass through the exhaust system to atmosphere. The oil may
combust in the catalytic converter and damage it.
Changing engine oil
The engine oil must be changed at the intervals stated in the Service
schedule or according to the service interval indicator ⇒page 16.
WARNING
•Only carry out the engine oil change, if you have the required
professional knowledge!
•Read and observe the warning notes ⇒page 219, “Working in
the engine compartment” before working in the engine compart-
ment.
•Let the engine cool down - risk of burning from hot oil.
•Wear an eye protection - risk of caustic burns due to oil
splashes.

Inspecting and Replenishing
230
•Do not place the battery in direct daylight in order to protect the battery
housing from the effects of ultra-violet light.
For the sake of the environment
A removed battery is a special type of waste which is harmful to the envi-
ronment - contact your specialist garage regarding disposing of the
battery.
Note
Please also refer to the guidelines ⇒page 233, “Disconnecting and
reconnecting the battery”, also after connecting the battery.
Battery with a charge level indicator, the so-called
magic eye
There is a so-called magic eye ⇒fig. 175 located on the top of the battery.
The “magic eye” changes its colour in line with the charge state of and
electrolyte level in the battery.
Air bubbles can influence the colour of the “magic eye”. For this reason
carefully knock on the “magic eye” before carrying out the check.
•Green colour - the battery is adequately charged.
•Dark colour - the battery has to be charged
•Colourless or yellow colour - have the battery checked by a specialist
garage.
Batteries, which are more than 5 years old, must be replaced. We recom-
mend you have the electrolyte level inspected and adjusted to the correct
level or the battery replaced if necessary by a specialist garage.
Caution
If the vehicle has not been driven for more than 3 to 4 weeks, the battery
will discharge because certain electrical components consume electricity
(e.g. control units) also in idle state. You can prevent the discharging of
the battery by disconnecting the negative terminal or charging the battery
constantly with a very low charging current. Please also refer to the notes
when working on the battery ⇒page 228, “Working on the battery”.
Inspecting the electrolyte level
The battery is practically maintenance-free under normal operating
conditions. We do, however, recommend that you have the electrolyte
level inspected from time to time by a specialist garage when outside
temperatures are high or when driving on long trips. You should also
check the electrolyte level ⇒page 231 each time the battery is charged.
The battery acid level will also be checked as part of the Inspection
Service.
