Radiator fan
The radiator fan switches on automatically by
itself
An auxiliary electric radiator fan switches on
and off depending on coolan t temperature
and other vehicle operating conditions .
After you switch the engine off, the auxiliary
fan can continue running for up to 10 minutes
- even with the ignition off. It can even switch
on again later by itself<=>.& , if
- the temperature of the engine coolant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
A WARNING
-To reduce the risk of personal injury nev­
er touch the radiator fan.
- The auxiliary electric fan is temperature
controlled and can switch on suddenly
even when the engine is not running.
- The auxiliary radiator fan switches on au­
tomatically when the engine coolant
reaches a certain temperature and will
continue to run until the coolant temper­
ature drops.

.. Read the brake fluid level from the brake
fluid reservoir <=>
fig. 165, <=> page 220,
fig. 159.
T he brake fluid level must be be­
tween the "MIN" and "MAX" markings.
The location of the brake fluid reservoir can be seen in the engine compartment illustration
<=>page 220.
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads. This is not cause for alarm.
If the brake fluid level falls considerably be­
low the "MIN" mark, the brake warning/indi­
cator light . (U.S. models)
I. (Canadian
models) will come on
c:> page 18 . Do not con­
tinue to operate the vehicle. The complete
brake system should be thoroughly checked
by an authorized Audi dealer or other quali­
fied facility and the cause corrected . If the
brake fluid level is too low, the brake warning/
indicator light will illuminate. Contact an au­
thorized Audi dealer
immediately.
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician.
Brake fluid absorbs moisture from the air . If
the water content in the brake fluid is too
high, corrosion in the brake system may result
after a period of time. The boiling point of the
brake fluid will also decrease considerably and
decrease braking performance.
Therefore, the brake fluid must be changed
every two years . Always use new brake fluid
which conforms to Federal Motor Vehicle
Standard "FMVSS 116 DOT 4".
The brake fluid reservoir can be difficult to
reach, therefore, we recommend that you
have the brake fluid changed by your author­
ized
Audi dealer. Your dealer has the correct
tools, the right brake fluid and the know-how
to do this for you.

It is important that the inflation pressu re is
regularly checked and maintained at recom­
mended levels .

What you can do to avoid tire and rim
damage
Low aspect ratio t ires can be damaged more
easi ly by impact with potho les, curbs, gu llies
or ridges on the road, part icularly if the t ire is
underinflated .
I n o rder to m inim ize the o ccu rrence of impact
damage to the tires of your vehicle, we recom­
mend that you observe the following precau­
tions:
- Always mainta in recommended inflat ion
pressures. Check your tire pressure every
2,000 miles (3,000 km) and add air if neces­
sary .
- Drive carefu lly on roads with potholes, deep
gullies or ridges. The impact from driving
thro ugh or over such obstacles can damage
your t ires. Impact with a curb may also
cause damage to your tires.
- After any impact, immediately inspect your
t ires or have them inspected by the neares t
authorized Aud i dealer . Replace a damaged
t ire as soon as possible .
- Inspect your t ires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see . Damage can lead to loss of
air and unde rinflat ion, wh ich could eventu­
ally cause t ire fail ure.
If you be lieve that a
t ire may have been damaged, replace the
tire as soon as possible.
- T hese tires may wea r more quick ly than oth­
ers.
- Please a lso remember that, whi le these t ires
deliver respons ive handling, they may ride
less comfortably and make mo re noise than
other c hoices.
Reduced performance in winter /cold

tended for maximum dry and wet road per­
formance and handling . They are not suitable
for cold, snowy or icy weather conditions. If
you drive under those c ircumstances, you
shou ld equ ip your vehicle w ith all -season or
winter tires, which offer bette r traction unde r
those conditions . We suggest you use the rec­
ommended snow o r all-season t ires specified
for yo ur vehicle , or thei r equivalent .

Tire pressure
monitoring system
ill General notes
E ach tire, including the spare ( if provided),
shou ld be checked monthly wh en co ld and in­
flated to t he inflat io n pressure recommended
by the veh icle man ufact urer on t he veh icle
placard or tire inf lation pressure labe l. (If your
vehicle has tires of a different size than the
size indicated on the vehicle placard or tire in ­
flat ion pressure labe l, you should determine
the proper t ire inflation press ure for those
t i res).
As an added safety feature, your ve hicle has
been equipped with a tire pressure monitoring
system (TPMS) that illum inates a low tire
pressure tell tale when one or more of your
t ires is s ignificantly under-inflated . According­
ly, when the low tire pressure telltale illumi­
nates, you shou ld stop and check you r tires as
soon as possib le, and inflate them to the
proper p ress ure. Driving on a sig nifican tly u n­
der -inflated t ire causes the tire to overhea t
and can lead to tire fa ilure . Under-inflation al­
so reduces fuel eff iciency and tire tread life,
and may affect the vehicle's hand ling and
stopp ing ability.
Please note that the TPMS is not a substit ute
for proper tire maintenance, and it is the driv­
er 's respons ibility to maintain correct tire
pressure, even if under-inflation has not
