Dispose of the 12-volt vehicle battery in accordance with the regulations. 12-volt vehicle
batteries may contain toxic substances such as sulphuric acid and lead.
Electrolyte can pollute the environment. Clean up any service fluid leakages and dispose of
them properly.

First read and observe the introductoryinformation and safety warnings⇒
Introduction
12-volt vehicle battery
Fault in the alternator. Go to a qualified workshop. Have the electrical system checked. Switch
off any electrical consumers that are not required. The 12-volt vehicle battery will not be charged by
the alternator while the vehicle is in motion. The start/stop system cannot start the engine.

Introduction
This chapter contains information on the followingsubjects:
⇒ Types of tyre monitoring systems
⇒ Tyre Pressure Loss Indicator
⇒ Tyre Pressure Monitoring System
⇒ Troubleshooting for the Tyre Pressure Loss Indicator
⇒ Troubleshooting for the Tyre Pressure Monitoring System
The tyre monitoring system warns the
driver when the tyre pressures get too
low.
Incorrectly securing the battery and using incorrect 12-volt vehicle batteries can cause
short circuits, fire and serious injuries.
•Always use maintenance-free and leak-proof 12-volt vehicle batteries that have the
same properties, specifications and dimensions as the factory-fitted 12-volt vehicle
battery.
•In vehicles with the 12-volt vehicle battery in the luggage compartment, ensure that the
breather hose is connected properly to the 12-volt vehicle battery. Make sure that no
open gas discharge openings are located in the area around the positive battery
terminal. If there is an open breather opening in this area, it must be closed off with a
sealing plug. The breather hose must be connected to the open breather opening in the
area of the negative terminal.
WARNING
A highly explosive mixture of gases is given off when the 12-volt vehicle battery is being
charged.
•12-volt vehicle batteries should only be charged in well-ventilated spaces.
•Never charge a 12-volt vehicle battery that is frozen or that has thawed. Discharged 12-
volt vehicle batteries can already freeze at temperatures of around 0°C (+32°Fyf.
•The 12-volt vehicle battery must be replaced if it has ever been frozen.
•Incorrectly connected cables can cause a short circuit. First connect the positive cable
and then the negative cable.
WARNING
•Never connect or disconnect 12-volt vehicle batteries if the ignition is switched on or
the engine is running. Never use a 12-volt vehicle battery that does not correspond with
the vehicle's specifications. This can damage the electrical system or electronic
components, which can cause electrical faults.
•Never connect equipment that supplies electric power, such as solar panels or a
battery charger, to the 12-volt socket or to the cigarette lighter to charge the 12-volt
vehicle battery. This can damage the vehicle electrical system.
NOTICE

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.
With a DSG® dual clutch gearbox, move the selector lever to position P DSG® dual clutch
gearbox.

First read and observe the introductoryinformation and safety warnings⇒
Introduction
The caps protect the wheel bolts and should be placed fully back in position after changing the
wheel.
Removing and fitting the caps
•Removing: take the wire hook from the vehicle tool kit ⇒ Vehicle toolkit.
•Insert the wire hook through the opening in the cap ⇒ Fig. 243 and pull off in the direction of
the arrow.
•Fitting: press the caps on the bolts as far as they will go.
The anti-theft wheel bolt has a separate cap. It only fits onto the anti-theft wheel bolts and not
onto conventional wheel bolts.
Changing a wheel
Introduction
This chapter contains information on the followingsubjects:
⇒ Preparations for changing a wheel
⇒ Wheel bolts
⇒ Lifting the vehicle with the jack
⇒ Changing a wheel
⇒ After changing a wheel
Some models are delivered from the factory without a jack or box spanner. If this is the case, the
wheel should be changed by a qualified workshop.
The vehicle jack supplied with the vehicle is only designed for changing a wheel when one vehicle
tyre is damaged and has to be replaced. If both tyres on one side of the vehicle, both tyres on one
axle, or all tyres are damaged, seek expert assistance.
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 ⇒:
Changing a wheel can be dangerous, especially when carried out at the side of a road.
Please note the following steps in order to reduce the risk of serious injuries:
•Stop the vehicle as soon as it is possible and safe to do so. Park the vehicle at a safe
distance from moving traffic in order to carry out the wheel change.
•All passengers and children in particular must be at a safe distance and away from
your area of work during the wheel change.
•Switch on the hazard warning lights to warn other road users.
•Check that the surface the vehicle is parked on is level and firm. If necessary use a
large, strong board or similar support for the vehicle jack.
•Only change the wheel yourself if you feel confident carrying out the procedure. If not,
seek expert assistance.
•Always use suitable and undamaged tools to change the wheel.
•Always switch off the engine, switch on the electronic parking brake and move the
selector lever to the position P or select a gear on a manual gearbox in order to reduce
the risk of unintended vehicle movement.
•The wheel bolt tightening torque should be checked with a torque wrench immediately
after changing a wheel.
•In the case of vehicles with a Tyre Pressure Loss Indicator, the system must be re-
synchronised immediately after new tyres are fitted ⇒ Tyre monitoring systems.
WARNING

Crank the jack further until the wheel is just clear of the ground.
Changing a wheel

First read and observe the introductoryinformation and safety warnings⇒
Introduction
Removing the wheel
•Observe the checklist ⇒ Preparations for changing a wheel.
•Loosen the wheel bolts ⇒ Wheel bolts.
•Jack up the vehicle ⇒ Lifting the vehicle with the jack.
•Using the hexagon socket in the screwdriver handle ⇒ Fig. 248, completely unscrew the
loosened wheel bolts and place them on a clean surface.
•Remove the wheel.
Fitting the spare wheel or temporary spare wheel
Note the tyre direction of rotation ⇒ Tyre lettering and tyre type.
•Put the wheel in place.
•Screw in the anti-theft wheel bolt using the adapter at position ⇒ Fig. 245② or ③ and tighten it
slightly in a clockwise direction.
•Screw in all the other wheel bolts in clockwise direction and tighten them slightly.
•Lower the vehicle with the jack.
•Use the box spanner to tighten all the wheel bolts securely in a clockwise direction ⇒. Do
not tighten the bolts in clockwise or anticlockwise sequence. Tighten them in diagonal
sequence.
•Fit the caps, wheel centre trim or wheel cover ⇒ Hubcaps.
Incorrect use of the vehicle jack can cause the vehicle to slip off the jack, which can lead
to severe injuries. Please note the following to help reduce the risk of injuries:
•Only use vehicle jacks that have been approved by Volkswagen for your vehicle type.
Other vehicle jacks could slip out of position – this includes vehicle jacks supplied
with other Volkswagen models.
•The ground must be firm and level. Soft ground or surfaces at an incline under the
vehicle jack may cause the vehicle to slip off the jack. If necessary use a large, strong
board or similar support for the vehicle jack.
•On a hard, slippery surface (such as tilesyfXVHDUXEEHUPDWRUVLPLODUWRSUHYHQWWKH

•Fit the vehicle jack only at the points described. The jack claw must securely grip the
vertical rib under the side member ⇒ Fig. 247.
•Never place any part of your body (e.g. an arm or legyfXQGHUQHDWKWKHYHKLFOHLIWKH
latter is only supported by the vehicle jack.
•If you have to work underneath the vehicle, use suitable stands to provide extra
support for the vehicle.
•Never lift the vehicle when the engine is running, or if the vehicle is tilted to the side or
on a gradient.
•Never start the engine when the vehicle is raised on a vehicle jack. Engine vibrations
can cause the vehicle to fall off the vehicle jack.
