The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration

been restored to norma l. Even t hough the re is
an e lec tric coolant level sensor, we s till rec ­
ommend you check the coolant leve l from
time to time .
Coolant loss
Coolant loss may indi cate a leak in the coo ling
sys tem. In the event of coolant loss, the cool­
ing system should be inspected immedia tely
by your authorized A udi dealer. It is not
enough merely to add coolant.
I n a
s ealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
A WARNING
The cooling system is unde r press ure and
can get ve ry hot. Reduce the risk of sca ld­
ing from hot coolant by following these
steps.
- Turn off the engine and allow it to coo l
down.
- Protect yo ur face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and very carefu lly in
a counter-clockwise direction wh ile ap­
plying light, downward pressure on the
t op of the cap .
- To avoid being bu rned, do not spill ant i­

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.
Tires and wheels 251
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 .,.. •

2 7 4 Emergency situations
This might happen, for e xamp le, when
h eavy components such as the engine
b lock or transmiss io n are removed.
- When removing heavy components li ke
these, ancho r vehicle to ho ist o r add cor­
responding weig hts to ma inta in the cen ­

(D Note
- Be awa re of the fo llowing points befo re
li fting the veh icl e:
- The vehicle should never be lifted or
jacked up from underneath the engine oil pan, the transmission housing , the
front or rear axle or the body side members. This could lead to serious
damage.
- To avoid damage to the underbody or
chassis frame, a rubber pad must be
inserted between the floor jack and
the lift points .
-Before driving over a workshop hoist,
check that the vehicle weight does not
exceed the permissible lifting capacity
of the hoist .
- Before driving over a workshop hoist,
ensure that there is sufficient clear­ ance between the hoist and low parts
of the vehicle.

28 2 Con sum er Inf ormation
-Always make sure the transmission se­
lector lever (automatic transmiss ion) is
in "P" (Park position) or Neutral (manual
transmission) and the park brake is firm­
ly applied.
@) For the s ake of the environment
-Changing the engine settings will ad­
versely affect emission levels. This is det­
rimental to the environment and increas­
es fuel consumption .
- Always observe environmental regula­
tions when disposing of old engine oil,
used brake fluid, dirty engine coolant,
spent batteries or worn out tires.
- Undeployed airbag modules and preten­
s ioners might be classified as Perchlo­
rate Material -spec ial handling may ap­
ply, see www.dtsc.ca .gov/hazardous­
waste/perch lorate. When the veh icle or
parts of the restraint system including
airbag modules safety belts with preten­
sioners are scrapped, all app licable laws
and regulations must be observed . Your
authorized Audi dealer is familiar with
these requirements and we recommend
that you have your dealer perform this
