No oil must be refilled.
Oil level within range
B
Oil can be refilled. Afterwards, the oil level can lie in the range
A
.
Oil level within range
C
The engine must be topped up with oil so that the oil level at least reaches the
range
B
.
The engine consumes a little oil. The oil consumption may be as much as 0.5 l/
1 000 km depending on your style of driving and the conditions under which you
operate your vehicle. Consumption may be slightly higher than this during the
first 5 000 kilometres.
The oil level must be checked at regular intervals. We recommend after each time
you refuel or prior to making a long journey.
We recommend maintaining the oil level within the range A
, but not above , if
the engine has been operating at high loads, for example, during a lengthy motor-
way trip during the summer months, towing a trailer or negotiating a high moun- tain pass.
The warning light in the instrument cluster will indicate whether the oil level is too low » page 17 ,  Engine oil . Check the oil level using the dipstick as soon as
possible. Add oil accordingly.
CAUTION
The oil level must not exceed the range A » Fig. 107 – there is a risk of damaging
the exhaust system!

›Check the level of coolant in the coolant expansion bottle
» Fig. 108. The cool-
ant level when the engine is cold must lie between the “MIN” and “MAX” mark-
ings. The level may also rise slightly above the “MAX” marking when the engine is warm.
If the coolant level in the coolant expansion tank is too low, this is indicated by
the warning light  lighting up in the instrument cluster » page 18,  Coolant .
We still recommend inspecting the coolant level directly at the reservoir from
time to time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the system. Do
not merely top up the coolant. Have the cooling system checked by a specialist
garage.

Replenishing
First read and observe the introductory information and safety warn-
ings
on page 132.
Only top up with new coolant.
›

WARNING■It is prohibited to work with naked flames or lights.■It is prohibited to smoke or carry out any activities that produce sparks.■
Never use a damaged vehicle battery – risk of explosion!
■
Never charge a frozen or thawed vehicle battery – risk of explosion and
chemical burns!
■
Replace a frozen vehicle battery.
■
Never jump-start vehicle batteries with insufficient acid levels – risk of ex-
plosion and chemical burns.
WARNING■ When you charge a battery, hydrogen is released, and a highly explosive gas
mixture is also produced. An explosion can be caused through sparkling over during unclamping or loosening of the cable plug while the ignition is on.■
Creating a bridge between the poles on the battery (e.g. with a metal object
or cable) creates a short circuit - risk of melting the lead bars, and risk of ex-
plosion, battery fire and acid splashes.
■
Avoid creating sparks when working with cables and electrical devices.
Strong sparking represents a risk of injury.
■
Before carrying out any work on the electrical system, switch off the engine,
the ignition and all of the electrical components and disconnect the negative
terminal ( ) of the battery.
CAUTION
Improper handling of the battery can lead to damage. We recommend having all
work on the vehicle battery carried out by a specialist garage.
CAUTION
■ The vehicle battery must only be disconnected if the ignition is switched off,
otherwise the vehicle's electrical system (electronic components) can be dam-
aged. When disconnecting the battery from the vehicle first disconnect the nega- tive terminal ( ) and only then the positive terminal ( ) of the battery.■
When connecting the battery to the electrical system, connect the positive ter-
minal ( ) first and then the negative terminal ( ) of the battery. Under no circum-
stances must the battery cables be connected incorrectly – risk of a cable fire.
■
Ensure that battery acid does not come into contact with the bodywork – risk of
damage to the paintwork.
■ Do not place the battery in direct daylight in order to protect the vehicle battery
housing from the effects of ultra-violet light.■
If the vehicle has not been driven for more than 3 to 4 weeks, the battery will
discharge. This is because certain electrical components consume electricity (e. g.
control units) also in idle state. The battery discharge can be prevented by discon-
necting the negative terminal ( ) of the battery or by ensuring the battery is con-
tinuously charged with very low charging current.
■
If the vehicle is frequently used for making short trips, the vehicle battery will
not have time to charge up sufficiently and may discharge.
For the sake of the environment
A vehicle battery that has been removed is a special type of hazardous waste.
These must be disposed of in accordance with national legal regulations.
Note
You should replace batteries older than 5 years.
Checking the battery electrolyte level
Fig. 110
Vehicle battery: Electrolyte level
indicator
First read and observe the introductory information and safety warn-
ings on page 134.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called
magic eye » Fig. 110 , the electrolyte level can be determined by looking at the
change in colour. 
135Inspecting and replenishing

Air bubbles can influence the colour of the indicator. For this reason carefully
knock on the indicator before carrying out the check.
› Black colour – electrolyte level is correct.
› Colourless or light yellow colour – electrolyte level too low, the battery must be
replaced.
Vehicles with a START-STOP system are fitted with a battery control unit for checking the energy level for the recurring engine start.
We recommend that you have the acid level checked regularly by a specialist ga-
rage, especially in the following cases.
› High external temperatures.
› Longer day trips.
› After each charge.
CAUTION
For technical reasons, on vehicles with the description “AGM”, the electrolyte lev-
el cannot be checked.
Note
The battery acid level is also checked regularly by a specialist garage as part of
the inspection service.
Operation in winter
First read and observe the introductory information and safety warn-
ings
on page 134.
The vehicle battery only has a proportion of the starting power in lower tempera-
tures. A discharged vehicle battery may already freeze at temperatures just be-
low 0 °C .
We therefore recommend that you have the battery checked and, if necessary, re-
charged by a specialist garage before the start of the winter.

Charging
First read and observe the introductory information and safety warn-ings
on page 134.
A properly charged vehicle battery is essential for reliably starting the engine.
› Switch off the ignition and all of the electrical components.›Only when performing a “quick-charge”, disconnect both battery cables (first
“negative”, then “positive”).›
Attach the terminal clamps of the charger to the battery terminals (red = “posi- tive”, black = “negative”).
›
Plug the mains cable of the charger into the power socket and switch on thedevice.
›
After charging has been successful: Switch off the charger and remove themains cable from the power socket.
›
Only then disconnect the charger's terminal clamps.
›
Reconnect the cables to the battery (first “positive”, then “negative”).
It is not necessary to disconnect the cables of the battery if you recharge the ve-
hicle battery using low amperages (for example from a mini-charger). Refer to the
instructions of the charger manufacturer .
A charging current of 0.1 multiple of the total vehicle battery capacity (or lower) must be used until full charging is achieved.
It is necessary to disconnect both cables before charging the battery with high
amperages, known as “ rapid charging”.
The vent plugs of the vehicle battery should not be opened for charging.
WARNING“Quick-charging” the vehicle battery is dangerous and requires a special
charger and specialist knowledge.
CAUTION
On vehicles with the START/STOP system, the pole terminal of the charger must
not be connected directly to the negative terminal of the vehicle battery, but only
to the engine earth » page 152, Jump-starting in vehicles with the START-STOP
system .
Note
We therefore recommend that vehicle batteries be rapid charged by a specialist
garage.
136General Maintenance

ReplaceFirst read and observe the introductory information and safety warn-
ings
on page 134.
When replacing a battery, the new vehicle battery must have the same capacity,
voltage, amperage and be the same size. Suitable vehicle battery types can be purchased from a specialist garage.
We recommend having the battery replaced by a specialist garage, where the
new vehicle battery will be installed properly and the original battery will be dis-
posed of in accordance with national regulations.

Disconnecting and reconnecting
First read and observe the introductory information and safety warn-
ings
on page 134.
On disconnecting and reconnecting the vehicle battery the following functions
are initially deactivated or are no longer able to operate fault-free:
OperationOperating measureEnter radio code number» Radio manualSetting the clock» page 14Data in the multifunction display are deleted.» page 13
Note
We recommend having the vehicle checked by a specialist garage in order to en-
sure full functionality of all electrical systems.
Automatic load deactivation
First read and observe the introductory information and safety warn-ings
on page 134.
The vehicle voltage control unit automatically prevents the battery from discharg-
ing when the battery is put under high levels of strain. This manifests itself by the following.
› The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
› Where necessary, large convenience consumers such as seat heaters and rear
window heaters have their power limited or are shut off completely in the event of an emergency.
CAUTION
■ Despite such intervention by the vehicle electric system management, the vehi-
cle battery may be drained. For example, when the ignition is switched on a long
time with the engine turned off or the side or parking lights are turned on during longer parking.■
Consumers that are supplied via a 12-V power socket can cause the vehicle bat-
tery to discharge when the ignition is switched off.
Note
Driving comfort is not impaired by consumers being deactivated. The driver is of-
ten not aware of it having taken place.
