Snow chains
Snow chains may be fitted on ly to the front
wheels, and only to certain tire sizes. Ask your
authorized Audi dealer on whic h tire sizes
snow chains can be used.
If you are going to use snow chains , then you
must install them on the front wheels at
least.
The snow chains must have low-profile links
and must not be thicker than 0.53 inch
(13.S mm), including the lock .
Remove wheel center covers and tr im discs
before putting snow cha ins on your vehicle
¢ Q). For safety reasons cover caps must the n
be fitted over the whee l bolts. These are ava il-
ab le from authorized Audi dea lers.
A
WARNING
Using the wrong snow chains for your vehi -
cle or installing them incorrectly can in-
crease the risk of loss of control leading to
ser ious personal injury.
- Snow chains are ava ilable in different
sizes. Always make sure to follow the in-
struct ions provided by the snow chain
manufacturer .
- When driving with snow chains never
dr ive faster than the speed permitted for
your specific snow cha ins.
- Always observe local regulat ions.

Note
- Remove snow cha ins before driving on
roads not covered with snow to avoid
damaging t ires and wear ing the snow
chains down unnecessar ily.
- Snow chains, wh ich come into d irect con-
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitab ly covered. Check
the position of the snow chains after
driving a few yards and correct if neces-
sa ry. Follow the instructions from t he
snow cha in manufacture r when doing so.

Tips
Where snow chains are mandatory on cer-
tain roads, th is normally a lso applies to ve-
hicles with all-whee l drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of wheel bo lts is matched to the
factory installed rims. If different rims are fit-
ted, the correct whee l bolts with the right
length and correct ly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly.
In certa in circumstances, you may not use
wheel bolts from a different vehicle - even if it
is the same model¢

A
WARNING
-
Improperly t ightened or ma inta ined wheel
bo lts ca n become loose causing loss of
control, a coll is ion and serio us pe rsonal in-
ju ry.
- Always keep t he wheel bo lts and the
threads in the wheel hubs clean so the
wheel bo lt s can t urn easily and be prop-
erly tightened.
- Never grease or oil the wheel bolts and
the threads in the whee l hubs . They can
become loose while driving if g reased or
oiled, even if tightened to the specified
torque.
- Only use whee l bolts that belong to the
rim being installed.
- Never use different wheels bo lts on yo ur
vehicle .
- Always maintain the correct t ightening
torque for the whee l bolts to reduce the
risk of a whee l loss. If the tightening tor-
que of the whee l bolts is too low, they
can loosen and come out when the vehi-
cle is mov ing. If the tightening torque is
too high, the wheel bolts a nd threads
