Warning symbols on the vehicle battery
SymbolMeaningAlways wear eye protection.Battery acid is severely caustic. Always wear gloves and eye protec- tion.Keep fire, sparks, open flames and lit cigarettes well clear of the ve-
hicle battery.SymbolMeaningWhen charging the vehicle battery, a highly explosive gas mixture is produced.Keep children away from the vehicle battery.WARNINGThere is risk of injuries, poisoning, chemical burns, explosions or fire when
working on the battery and on the electrical system. It is essential to comply
with the generally applicable rules of safety as well as the warning instruc-
tions outlined below.■
Keep children away from the vehicle battery.
■
Do not tilt the battery otherwise battery electrolyte may flow out of the bat-
tery vent openings. Protect your eyes by wearing safety goggles or a face
shield – risk of blindness!
■
Always wear protective gloves, eye and skin protection when handling the
vehicle battery.
■
The battery acid is strongly corrosive and must, therefore, be handled with
the greatest of care.
■
Corrosive fumes in the air irritate the air passages and lead to conjunctivitis
and inflammation of the air passages in the lungs.
■
Battery acid corrodes dental enamel and, if it comes into contact with the
skin, causes deep wounds that take a long time to heal. Repeated contact
with diluted acids causes skin diseases (inflammations, ulcers, slin cracks).
■
If any battery acid comes into contact with your eyes, rinse the affected eye
immediately with clean water for several minutes and consult a doctor imme-
diately!
■
Splashes of acid on your skin or clothes should be neutralised as soon as
possible using soap suds and then rinsed with plenty of water. If you swallow
battery acid, consult a doctor immediately!
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! 
168General Maintenance

WARNING (Continued)■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 electrical consumers and disconnect the negative termi-
nal ( ) 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's electrical system, first
disconnect the negative terminal ( ), then the positive terminal ( ).■
When connecting the battery to the vehicle's electrical system first connect the
positive terminal ( ), and only then the negative terminal ( ) of the battery. Un-
der no circumstances 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. Battery discharge can be prevented by discon- necting the negative terminal ( ) of the battery or by continuously charging the
battery 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 electrolyte levelFig. 134
Vehicle battery: Electrolyte level
indicator
First read and observe the introductory information and safety warn-
ings on page 168.
We recommend that you have the acid level checked regularly by a specialist ga-
rage, especially in the following cases.
› High outside temperatures.
› Long daily drives
› After each charge
» page 170.
On vehicles with a vehicle battery fitted with a colour indicator, known as the
magic eye » Fig. 134, the electrolyte level can be determined by looking at the
change in colour.
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.
Note
■ The battery acid level is also checked regularly by a specialist garage as part of
the inspection service.■
For technical reasons, on vehicles with the description “AGM”, the electrolyte
level cannot be checked.
■
Vehicles with a START-STOP system are fitted with a battery control unit for
checking the energy level for the recurring engine start.

Operation in winter
First read and observe the introductory information and safety warn-
ings
on page 168.
The vehicle battery only has some of its starting power at low temperatures. A
discharged vehicle battery may freeze at temperatures just below 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 168.
A properly charged vehicle battery is essential for reliably starting the engine.
›
Switch off the ignition and all of the electrical components.
›
Disconnect both battery cables (“negative” first, then “positive”) only when
“rapid charging” the battery.
›
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 thecharger on.
›
Once charging is complete: Switch off the charger and remove the mains 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 battery cables if you are recharging the vehi-
cle battery using low amperages (for example from a mini-charger). Refer to the
charger manufacturer's instructions .
A charging current of 0.1 multiple of the total vehicle battery capacity (or lower)
must be used until full charging is achieved.
Both cables must be disconnected before charging the battery with high amper-
ages, known as “ rapid charging”.
The vent plugs of the vehicle battery should not be opened for charging. 
170General Maintenance

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 188, Jump-starting in vehicles with the START-STOP
system .
Note
We therefore recommend that vehicle batteries be rapid charged by a specialist
garage.
Disconnecting or reconnecting
First read and observe the introductory information and safety warn-ings
on page 168.

Note
We recommend having the vehicle checked by a specialist garage in order to en-
sure full functionality of all electrical systems.
Replacing
First read and observe the introductory information and safety warn-
ings
on page 168.
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.

Automatic load deactivation
First read and observe the introductory information and safety warn-ings
on page 168.
The vehicle voltage control unit automatically prevents the battery from discharg-
ing when the battery is put under high levels of strain. This may be noticed from
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.

Towing the vehicle

Introduction
This chapter contains information on the following subjects:
Front towing eye
189
Rear towing eye
189
Vehicles with a tow hitch
189
Vehicles with manual transmission may be towed in with a tow bar or a tow rope
or with the front or rear wheels raised.
Vehicles with automatic transmission may be towed in with a tow bar or a tow
rope or with the front wheels raised. If the vehicle is raised at rear, the automatic
gearbox is damaged!
A tow bar is the safest way of towing a vehicle and also minimises any shocks.
Only use a tow rope if a suitable tow bar is not available.
The following guidelines must be observed when towing.
Driver of the tow vehicle›Release the clutch particularly gently when starting off or depress the accelera-
tor particularly gently if the vehicle is fitted with an automatic gearbox.›
On vehicles with a manual transmission, only push down on the accelerator pedal once the rope is taught.
The maximum towing speed is 50 km/h.
Driver of the towed vehicle
›
Switch on the ignition so that the steering wheel is not locked and so that the turn signal lights, horn, windscreen wipers and windscreen washer system can
be used.
›
Take the vehicle out of gear or move the selector lever into position N if the ve-
hicle is fitted with an automatic gearbox.
Please note that the brake servo unit and power steering only operate if the en-
gine is running. If the engine is not running, significantly more physical force is re-
quired to depress the brake pedal and steer the vehicle.
If using a tow rope, ensure that it is always kept taught.
CAUTION
■ Do not tow start the engine – there is a risk of damaging the engine and the
catalytic converter. The battery from another vehicle can be used as a jump-start
aid » page 186 , Jump-starting .■
If the gearbox no longer contains any oil because of a defect, your vehicle must
only be towed with the driven wheels raised clear of the ground or on a special
breakdown vehicle or trailer.
■
The vehicle must be transported on a special breakdown vehicle or trailer if it is
not possible to tow in the vehicle in the way described or if the towing distance is greater than 50 km.
■
To protect both vehicles when tow-starting or towing, the tow rope should be
elastic. Thus one should only use plastic fibre rope or a rope made out of a simi-
larly elastic material.
■
While towing, take care to avoid impermissibly high tensile forces or jerky loads.
There is always a risk of excessive stresses and damage resulting at the points to
which you attach the tow rope or tow bar when you attempt to tow a vehicle
which is not standing on a paved road.
