WARNING■The following instructions must be followed at all times when working on
the engine compartment » page 137.■
Never open the end cover of the coolant expansion reservoir while the
engine is still warm. The cooling system is pressurised - risk of scalding or
injury from splashes of coolant!
■
To protect against the coolant splashing, cover the cap with a cloth when
opening.
■
Coolant and coolant fumes are harmful - avoid contact with the coolant. If
the coolant comes into contact with the eye or skin, wash the affected area
with plenty of water for several minutes, and where appropriate seek medi-
cal help.
CAUTION
Do not cover the radiator and install any parts (e.g auxiliary lights.) in front of
the air intakes - risk of the engine overheating.
Checking and refilling
Fig. 171
Coolant expansion reservoir
Read and observe and on page 141 first.
Check and refill coolant under the following conditions.
The vehicle is on a horizontal surface.
The engine is not warm (if the engine is warm the result of the check may
be wrong).
The engine is turned off.
Check the coolant level - The coolant level must lie between the marks
A
and
B
» Fig. 171. If the coolant level is below the mark
B
, top up with coolant.
Refilling
The reservoir must always contain a small amount of coolant »
.
›Place a cloth over the cap of the coolant expansion tank and
carefully un-
screw the cap.›
Always top up using coolant of the correct specification.
›
Turn the cap until it clicks into place.
The specification for the coolant is shown in the coolant expansion reservoir
» Fig. 171 .
If the specified coolant is not available, then refilling only with distilled or dem-
ineralised water, and get a specialist garage to correct the water-coolant addi-
tive mix as soon as possible.
CAUTION
■ With an empty expansion tank top up coolant. The system could aerate - risk
of engine damage! Stop driving! Switch off the engine and seek assistance
from a specialist garage.■
Do not fill the coolant above the mark
A
» Fig. 171 . The coolant could, when
heated, be expelled from the cooling system - risk of damage to the engine
parts.
■
If it is not possible to add coolant,
stop driving! Switch off the engine and
seek assistance from a specialist garage.
■
A coolant additive which does not correspond to the correct specification can
reduce the anti-corrosion effect of the cooling system - risk of damage to the
cooling system and the engine.
■
If non-distilled (non-demineralised) water has been used to top up, the cool-
ant should be replaced by a specialist garage - risk of engine damage.
■
A loss of coolant indicates leaks in the cooling system - risk of engine dam-
age. Top up with coolant and then seek assistance from a specialist garage.
Note
A coolant level which is too low is indicated in the instrument cluster by the
warning light and shown by the relevant message » page 34. We still recom-
mend inspecting the coolant level directly at the reservoir from time to time.141Inspecting and replenishing
ChargingRead and observe
and on page 142 first.
Only charge the battery when the ignition and all consumers are switched off.
Refer to the instructions of the charger manufacturer.
Charging
›
For vehicles withthe START-STOPsystem or auxiliary heater
, connect the -
terminal of the charger on the battery’s
-pole,
the -terminal of the charg-
er to the ground point of the engine » page 157.
›
For vehicles without the START-STOPsystem or auxiliary heating, connect
the charger terminals to the corresponding battery poles ( to
,
to
).
›
Plug the mains cable of the charger into the power socket and switch the
charger on.
›
Once charging is complete: Switch off the charger and remove the mains ca-
ble from the power socket.
›
Disconnect the terminals of the charger from the vehicle battery.
A charging current of 0.1 multiple of the total vehicle battery capacity (or low-
er) must be used until full charging is achieved.
WARNING■ When charging the vehicle battery, hydrogen is released - risk of explo-
sion. An explosion can be caused through sparking while unclamping or
loosening the cable plug.■
So-called“quick-charging” of the vehicle battery is dangerous and re-
quires a special charger and specialist knowledge. Therefore, have“Quick
loading” carried out by a specialist garage.
Disconnect/reconnect and change
Read and observe
and on page 142 first.
The new vehicle battery must have the same capacity, voltage, current and the
same size as the original battery.
We recommend you have the battery replaced by a specialist garage.
›
To disconnect , switch off the ignition and disconnect the negative terminal
first , then disconnect the positive terminal
.
›
When
reconnecting the battery, reconnect the positive terminal first
, then
connect the negative terminal .
After disconnecting and re-connecting the vehicle battery, the following func-
tions or devices are partially or completely inoperative.Function / deviceOperating measurePower windows» page 52Time settings» page 37
CAUTION
■ Disconnect the battery only with the ignition and consumers turned off - risk
of damaging the electrical system of the vehicle.■
Before disconnecting the battery, always close all electric windows other-
wise malfunctions of the window can occur.
■
Under no circumstances mix up the charging cables – risk of fire.
Note
After disconnecting and reconnecting the vehicle battery, we recommend hav-
ing the vehicle checked by a specialist to ensure that the full functionality of
the vehicle is guaranteed.144General Maintenance

We recommend having bulbs replaced by a specialist garage or seeking other
expert help in the event of any uncertainties.
▶ Switch off the ignition and all of the lights before replacing a bulb.
▶ Faulty bulbs must only be replaced with the same type of bulbs. The designa-
tion is located on the light socket or the glass bulb.
We recommend having the headlight settings checked by a specialist garage after replacing a bulb in the low, high or fog beam.
Visit a specialist garage if an LED diode is faulty.
