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 com-
ply with the general applicable safety rules as well as the warning instruc-
tions outlined below.■
Keep the vehicle battery away from people who are not completely inde-
pendent, especially children.
■
Do not tilt the battery otherwise battery electrolyte may flow out of the
battery 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 conjunctivi-
tis 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.
■
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
immediately!
■
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■ The use of open flames and light should be avoided.■Smoking and radio triggering activities should be avoided.■
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
explosion and chemical burns.
CAUTION
■ Improper handling of the vehicle battery may cause damage.■Ensure that battery acid does not come into contact with the bodywork – risk
of damage to the paintwork.■ If the vehicle has not been driven for more than 3-4 weeks, the battery will
discharge. Prevent the battery from discharging by disconnecting the battery's
negative terminal
or continuously charging the battery with a very low
charging current.■
Do not place the battery in direct daylight in order to protect the vehicle bat-
tery housing from the effects of ultra-violet light.
■
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.
Therefore these must be disposed of in accordance with national legal regula-
tions.
Note
■ We recommend having all work on the vehicle battery carried out by a spe-
cialist garage.■
You should replace batteries older than 5 years.

149Inspecting and replenishing
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 metal ob-
jects - cables) creates a short circuit - risk of damage to the battery, explo-
sion and burning of the battery, jets of acid spurting out.
■
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 en-
gine, the ignition and all electrical consumers and disconnect the negative
terminal
.
■
“Quick-charging” the vehicle battery is dangerous and requires a special
charger and specialist knowledge.
■
We therefore recommend that vehicle batteries be “rapidly charged” by a
specialist garage.
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 167, Jump-starting using the battery from
another vehicle .
Replacing
Read and observe
and on page 149 first.
The new vehicle battery must have the same capacity, voltage, current and
size as the original battery. 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
disposed of in accordance with national regulations.
Disconnecting and reconnecting
Read and observe
and on page 149 first.
Disconnecting
›
Switch off the ignition.
›First, disconnect the negative terminal
first, then the positive terminal
of the battery.
Connecting›
First, connect the positive
first, then the negative

system user manualTime settings» page 33
CAUTION
■ Disconnect the vehicle battery only with the ignition turned off - there is a
risk of damaging the electrical system of the vehicle.■
Under no circumstances must the battery cables be connected incorrectly –
risk of a cable fire.
Note
■ After disconnecting and re-connecting the vehicle battery, we recommend
having the vehicle checked by a specialist to ensure that the full functionality
of all electrical systems is guaranteed.■
The data of the multi-function display will be reset.
Automatic load deactivation
Read and observe
and on page 149 first.
The vehicle voltage control unit automatically prevents the battery from dis-
charging when the battery is put under high levels of strain. This manifests it-
self 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.
151Inspecting and replenishing
The battery of another vehicle can be used to jump-start your vehicle if the en-
gine will not start because the battery is flat.WARNING■ Pay attention to the warning instructions relating to working in the en-
gine compartment » page 141.■
A discharged vehicle battery may already freeze at temperatures just be-
low 0 °C. If the battery is frozen, do not jump start with the battery of an-
other vehicle – there is a risk of explosion!
■
Keep any sources of ignition (naked flame, smouldering cigarettes, etc.)
away from the battery – risk of explosion!
■
Never jump-start vehicle batteries with insufficient acid levels – risk of
explosion and chemical burns.
■
The vent screws of the battery cells must be tightened firmly.
Note
We recommend you buy jump-start cables from a car battery specialist.

to a solid metal component firmly connected to the en-
gine block or to the engine block itself.
Starting engine
›
Start the engine on the vehicle providing the power and allow it to idle.
›
Start the engine of the vehicle with the discharged battery.
›
If the engine does not start, halt the attempt to start the engine after 10 sec-
onds and wait for thirty seconds before repeating the process.
›
Remove the jumper cables exactly in the reverse sequence as for clamping.
On vehicles with the START-STOP system, the jump-start cable of the charger
must never be connected directly to the negative pole of the vehicle battery,
but only to the engine earth.
› 1.2 l/63 kW TSI and 1.2 l/77 kW TSI engines
» Fig. 147 -
› 1.4 l./90 kW engine
» Fig. 147 -
› 1.6 l./77 kW TDI CR engine
» Fig. 147 -
Both batteries must have a rated voltage of 12 V. The capacity (Ah) of the bat-
tery supplying the power must not be significantly less than the capacity of
the discharged battery in your vehicle.
Jump-start cables
Only use jump-start cables which have an adequately large cross-section and
insulated terminal clamps. Observe the instructions of the jumper lead manu-
facturer.
Positive cable – colour coding in the majority of cases is red.
Negative cable – colour coding in the majority of cases is black.
167Emergency equipment and self-help
WARNING■Do not clamp the jump-start cable to the negative terminal of the dis-
charged battery. There is the risk of detonating gas seeping out of the bat-
tery being ignited by the strong spark resulting from the engine being star-
ted.■
The non-insulated parts of the terminal clamps must never touch each
other – there is a risk of short circuit!
■
The jump-start cable connected to the positive terminal of the battery
must not come into contact with electrically conducting parts of the vehicle
– there is a risk of short circuit!
■
Route the jump-start cables so that they cannot be caught by any rotat-
ing parts in the engine compartment.
■
There must not be any contact between the two vehicles, otherwise cur-
rent may flow as soon as the negative terminals are connected.
Towing the vehicle

For towing a braided tow rope is to be used » Fig. 148-
.
When towing, the following guidelines must be observed.
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 the rear, the au-
tomatic gearbox will be damaged!
Driver of the tow vehicle›
Engage the clutch gently when starting off or depress the accelerator partic-
ularly gently if the vehicle is fitted with an automatic gearbox.
›
Only then, approach correctly when the rope is taut.
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, 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
vehicle is fitted with an automatic gearbox.
Please note that the brake servo unit and power steering only operate if the
engine is running. If the engine is not running, significantly more physical force
is required to depress the brake pedal and steer the vehicle.
If using a tow rope, ensure that it is always kept taught.
Both drivers should be familiar with the problems which might possibly occur while a vehicle is being towed. Unskilled drivers should not attempt to tow an-
other vehicle or to be towed in one.
The vehicle must be transported on a special breakdown vehicle or trailer if it
is not possible to tow the vehicle in the way described or if the towing dis-
tance is greater than 50 km.
WARNING■ When towing, respect the national legal provisions, especially those
which relate to the identification of the towing vehicle and the vehicle be- ing towed.■
When towing, exercise increased caution.
■
For towing no spiral tow rope is to be used » Fig. 148-
, the towing eye
may unscrew out of the vehicle - there is a risk of accidents.
■
The tow rope should not be twisted - there is a risk of accidents.
