12-volt vehicle battery
Introduction
This chapter contains information on the followingsubjects:
⇒ Checking the electrolyte level of the 12-volt vehicle battery 
⇒ Charging, replacing, disconnecting and connecting the 12-volt vehicle battery 
⇒ Troubleshooting 
The 12-volt vehicle battery is a component of the electrical system and serves to supply power in the
vehicle.

-volt vehicle battery. Discharged 12-volt vehicle batteries can already freeze
at temperatures of around 0°C (+32°F). Frozen 12-volt vehicle batteries must be renewed
immediately.

NOTICE
Do not expose the 12-volt vehicle battery to direct daylight for an extended time.


NOTICE
Protect the 12-volt vehicle battery against frost if the vehicle is left standing for extended periods.
-volt vehicle battery can freeze and be destroyed as a result.

When you start the engine after the 12-volt battery has been totally discharged or after jump
starting, you may find that system settings (time, date, personal convenience settings and
programming) have been changed or deleted. Check and correct the settings as necessary once the
12-volt vehicle battery has been sufficiently charged.

Charging, replacing, disconnecting and connecting the 12-volt vehicle battery
First read and observe the introductoryinformation and safety warnings⇒Introduction 
If you suspect that the 12-volt vehicle battery is damaged or faulty, go to a qualified workshop and
have the 12-volt vehicle battery checked.
Charging the 12-volt vehicle battery
The 12-volt vehicle battery should be charged by a qualified workshop, as the technology used in
factory-fitted 12-volt vehicle batteries requires voltage-limited charging ⇒ . Volkswagen
recommends using a Volkswagen dealership for this purpose.
Replacing the 12-volt vehicle battery
The 12-volt vehicle battery has been developed to suit the conditions of its installation location and
has special safety features. If a 12-volt vehicle battery has to be replaced, find out about the
electromagnetic compatibility, size and necessary maintenance, power and safety requirements for
the new 12-volt vehicle battery at a Volkswagen dealership before purchase. The ventilation opening
of the vehicle battery must always be on the negative terminal side: the ventilation opening on the
positive terminal side must always be sealed.
Only maintenance-free vehicle batteries compliant with the standards TL 825 06 and VW 7 50 73
should be used. These standards must be dated October 2014 or later.
Always have the 12-volt vehicle battery replaced by a qualified workshop, as the vehicle electronics
must be adapted as part of the replacement process. Only qualified workshops have the technology
required to carry out this adjustment correctly. Volkswagen recommends that the 12-volt vehicle
battery is replaced by a Volkswagen dealership.
Disconnecting the 12-volt vehicle battery
Please observe the following if the 12-volt vehicle battery has to be disconnected from the electrical
system in the vehicle:

Handling wheels and tyres

First read and observe the introductoryinformation and safety warnings⇒Introduction 

The tyres and wheel rims approved by Volkswagen have been carefully selected.
Rotating wheels
Regularly rotating the wheels as shown in the illustration ⇒ Fig. 193  is recommended to help ensure
that tyres wear evenly. All the tyres will then last for about the same time.
Volkswagen recommends having the wheels changed by a qualified workshop.

Tyres that are older than 6 years
Tyres age through physical and chemical processes that can impair their function. Tyres that have
been stored unused for an extended period of time age more quickly than tyres that are used all the
time.
Volkswagen recommends replacing tyres that are older than 6 years with new tyres. This also applies
to tyres which appear to still be in good condition and whose tread depth has not yet reached the
minimum value stipulated by legislation ⇒ .
Winter and all-year tyres also largely lose their effectiveness through ageing – regardless of the
remaining tread depth.
The age of each tyre can be determined using the manufacturing date ⇒ Tyre lettering and tyre

Preparations for changing a wheel
First read and observe the introductoryinformation and safety warnings⇒Introduction 
Checklist
The following actions must always be carried out in the given order in preparation for changing the
wheel ⇒ :

If your vehicle has a flat tyre, park the vehicle on a firm and level surface at a safe distance from
moving traffic.

Switch on the electronic parking brake Parking and manoeuvring.

Switch off the engine and remove the key from the ignition.

On wheels with a wheel cover, the anti-theft wheel bolt must be screwed into position
⇒ Fig. 204②  or ③ according to the position of the tyre valve ①. The wheel cover can otherwise
not be fitted.
Tightening torque of wheel bolts
Specified tightening torque for wheel bolts for steel or alloy wheels:
Nm
If the wheel bolts are corroded and difficult to turn, they must be replaced before the tightening
torque is checked and the wheel hub threads cleaned.
Never grease or oil the wheel bolts or the threads of the wheel hub.
The tightening torque should be checked with a properly functioning torque wrench immediately
after changing a wheel.

WARNING
Incorrectly tightened wheel bolts can loosen while the vehicle is in motion and cause accidents,
serious injury, and loss of control of the vehicle.
