First read and observe the introductoryinformation and safety warnings⇒
Introduction
The jack may be positioned only at the reinforcements on the underbody, which are located behind
the markings on the body ⇒ Fig. 246. Always use the jacking point closest to the wheel you are
working on ⇒.
Checklist
For your own safety, carry out the following points in the specified order ⇒:
Incorrectly tightened wheel bolts can loosen while the vehicle is in motion and cause
accidents, serious injury, and loss of control of the vehicle.
•Only use wheel bolts that belong to the wheel.
•Never use different wheel bolts.
•The wheel bolts and threads of the wheel hubs must be clean, free from oil and grease,
and turn easily.
•Always use the box spanner placed in the vehicle at the factory to loosen and tighten
the wheel bolts.
•Only loosen the wheel bolts by approximately one turn before raising the vehicle with
the vehicle jack.
•Never grease or lubricate the wheel bolts or the threads of the wheel hub. This could
cause them to loosen while the vehicle is in motion, even if the required torque setting
is used.
•Never remove the bolts on rims with bolted-on rings.
•If the tightening torque of the wheel bolts is too low, the wheel bolts and rims can
loosen while the vehicle is in motion. The wheel bolts and threads can be damaged if
the tightening torque is too high.
WARNING

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

Vehicle care
Notes on vehicle care
Regular and expert care helps to maintain the value of the vehicle.
Leaving stains, dirt and other deposits on the surface of vehicle components and cloth seat covers
for a long time can make it difficult to clean and treat them. Stains, dirt and deposits may become
impossible to remove, particularly if left for a long time.
For proper cleaning and care, Volkswagen recommends using Genuine care products that have
been matched to your vehicle. Consult a qualified workshop if you have any specific questions or if
vehicle parts are not listed.
1yf
Incorrect care and cleaning of vehicle parts can impair the safety features of the vehicle
and cause serious injury.
•Vehicle parts must be cleaned according to the manufacturer's instructions.
•Always use approved or recommended cleaning products.
•Do not use solvent-based cleaning products. Solvents can cause irreparable damage
to the airbag modules.
•Protect your hands and arms against parts with sharp edges, e.g. when cleaning the
underbody or the insides of the wheel housings.
WARNING
Dirty, misted or iced over windows reduce visibility and increase the risk of accidents and
severe injuries. This could impair the safety equipment of the vehicle.
•Only drive when you have a clear view through all windows.
•Do not treat the windscreen with water-repellent window coating agents. In
unfavourable conditions, they can cause increased dazzle.
