2013 AUDI A4 Links

Snow chains
Snow chains may be fitted only to the front
wheels, and only to certain tire sizes. Ask your
authorized Audi dealer on which tire sizes
snow chains can be used.
The snow chains must have low-profile links
and must not be thicker than 0.53 inch
(13.5 mm), including the lock .
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
~ 0. For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
~ 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
serious personal injury.
- Snow chains are available in different sizes. Always make sure to follow the in­
structions provided by the snow chain
manufacturer .
- When driving with snow chains never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
(D Note
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or
damage it . Therefore, make sure that the
snow chains are suitably covered . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
(j) Tips
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
vehicles with all wheel drive.

Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of wheel bolts is ma tched to the
factory inst alled rims. If diffe ren t rims are fit­
ted, the correct wheel bolts with the right length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly.
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model~
page 282 .
&_ WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control , a collision and serious personal in­
jury.
- Always keep the wheel bolts and the threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­
erly tightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can become loose while driving if greased or
oiled, even if tightened to the specified
torque .
- Only use wheel bolts that belong to the
rim being installed .
- Never use different wheels bolts on your
vehicle.
-Always maintain the correct tightening torque for the wheel bolts to reduce the risk of a wheel loss. If the tightening tor­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cle is moving.
If the tightening torque is
too high, the wheel bolts and threads
can be damaged and the wheel can be­
come loose.
(I} Note
The specified torque for the wheel bolts is
90 ft lbs. (120 Nm) with a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque wheel bolts .,.. •

have the ma lfunction corrected.
A WARNING
- If the tire pressure indicator appears in
the instrument cl uster display, one or
more of your tires is significantly under­
inflated. Reduce your speed immediately
and avoid any hard stee ring or braki ng
maneuvers. Stop as soon as possible and
check the t ires and the ir pressures. In­
flate the tire pres sure to the proper p res­
s u re as in dic ated on the vehicle 's t ire
pressure label ¢
page 238. Driving on a
significantly under-inf lated tire ca uses the tire to overheat and can
lead to tire
fa ilure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regu larly .
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­ paved roads), the pressure monitor indi ­
cato r may be delayed .
-Ask your authorized Aud i dea ler if run­
flat t ires may be used on you r vehicle.
Your vehicle registration becomes invalid
if you use these t ires when not perm it­
ted. Damage to your vehicle or accidents
could a lso result.
(D Tips
- The tire pressure mon itoring system
stops work ing whe n there is an ESC/ABS
m alfu nction.
- Us ing snow chains may result in a system
ma lf u nction.
- The tire pressure mon itoring system on
your Audi was deve loped using tires with
t he "AO" or "R O" ident ifi cat ion on the
tire s idewa ll
c> page 246 . We recom ­
mend using these tires.
Reset tire pressure monitoring system
Appl ies to vehicles: wit h tire p ressu re mo nito rin g system
If the tire pressure is adjusted, wheels are ro ­

radio or MMI*.
.. Before resett ing the TPMS, the current pres ­
sures of a ll four tires must correspond to
the specified values . Ad just the tire p ressu re
