Read an d follo wing the WARNINGS before
checking anything in the engine compartment
r::;,page 198.
Checking the engine coolant level
.. Park your vehicle on a level surface.
.. switch the ignition off.
.. Read the coolant level on the coolant expansion
tank
r::;, fig . 162 . The coolant level must be be ­
tween the mark ings when the engine in cold .
When the engine is warm it can be slightly
above the upper marking .
Adding coolant
Requirement: there must be a residual amount of
coolant in the expans ion tank
c> Q).
.. Let the engine cool down.
.. Place a cloth over the coolant expansion tank
cap and unscrew the cap counterclockwise
<=>& .
.,. Add coolant mixed in the correct ratio
r::;, page 205 up to the upper marking .
.. Make sure that the fluid level rema ins stable.
Add more coolant if necessary.
.. Close the cap secure ly.
A coolant loss s uggests a leak. Immediate ly drive
your veh icle to an authorized A udi dealer or au­
thor ized Audi Service Facility and have the cool­
ing system inspected.
If the cooling system is not
leaking, a loss can come from the coolant boiling
206
thro ugh ove rheating and being pushed out o f the
cooling system.
A WARNING
The cooling system is pressurized and can be­
come very hot. To reduce the risk of burns
from hot coolant:
- Do not open the coolant expansion tank cap
w ith the engine hot. There is a risk of burns .
- Stop the eng ine and a llow it to cool.
- Protect your face, hands and arms from es-
caping coolant and steam by covering the
coo lant tank cap with a large, thick cloth.
- Turn the coolant tank cap counterclockwise
slowly and keep light pressure on the cap.
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto the e x­
haust system or hot engine components.
The ethy lene glycol in engine coola nt can
catch fire under certa in circumstances.
- The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the o riginal container
away from ch ildren . The re is a risk of poison­
ing .
- W hen working in the engine compartment,
remember that the rad iator fa n can switch
on ev en if the ignition is switched off, wh ich
increases the risk of pe rsonal injury.
@ Note
Do not add coolant if the expans ion tank is
empty . Air cou ld enter the cooling system and
damage the eng ine. If this is the case, do not
continue driving. See an author ized Audi deal ­
er or a uth ori zed Audi Service Facility for a ssis­
ta nce .
. Radiator fan
The radiator fan switches on automatically by it­
self
An a uxiliary electric radiato r fan switches on and
off depending on coolan t temperature and other
vehicle ope rat ing cond itions .
After yo u sw itch the engine off, the aux ilia ry fan
can continue running for up to 10 m inutes -even .,,.

Checking and F ill in g
sure you are using the correct brake f luid .
The correct type of brake fluid is also indi­
cated on the brake fluid reservoir .
- The brake fluid must be new. Heavy use of
the brakes can cause a vapor lock if the
brake fluid is left in the system too long.
This can ser iously affect the effic iency of
the brakes as well as your safety . This
could res ult in an accident.
(D Note
Brake flu id will damage the paint of your vehi­
cle .
@ For the sake of the environment
Because of the problem of proper d isposa l of
brake fluid as well as the spec ia l tools re-
quired and the necessary expertise, we rec ­
ommend tha t you have the b rake fluid
changed by your author ized Audi dealer.
Battery
General information
The battery in yo ur Audi does not need any ma in­
tenance under normal operating conditions. Aud i
recommends having the electro lyte level check by
an author ized Audi dealer or author ized Audi
Service Fac ility when the re a re
high outside tem­
pe ratu res or when dr iv ing a ll day. The electroly te
leve l sho uld also be checked ea ch t ime the bat ­
t ery is charged
9 page 210 .
Have the battery checked when you br ing you r ve­
hicle in fo r an inspec tio n. It is a good idea to re­
p la ce the batte ry if i t is more than 5 ye ars old .
During certai n types of a irbag dep loyments, the
battery is disconnect ed from the vehicle electr i­
cal system fo r safety reasons
9 .&. in Repair, care
and disposal of the airbags on page 163.
Disconnecting the battery terminals
Some veh icle functions (such as power windows)
are not ava ilable when the batte ry is disco nnect­
ed. These functions must be programmed after
the ba ttery is reconnec ted. To avoid havi ng to do
t his , on ly disconnect the b attery from the veh icle
208
electrica l sys tem when that is necessa ry to pe r­
form repairs.
To reprogram the func tion s, proceed as fo llows:

Not running the vehicle for long periods of
time
If you do not d rive yo ur vehicle for several days or
weeks, e lectr ica l components are gradua lly re­
duced or switched off. Th is red uces energy con­
s u mption and maintains the vehicle's ability to
start over a long per iod of t ime ¢
page 128.
Some conven ience functions , such as inter ior
li ght ing or power seats* may not wo rk . These
convenienc e functions w ill be availabl e agai n
o nce you swi tch the ig nition on and sta rt the en ­
gine.
Winter operation Du ring the winter months , it is common for the
batte ry capaci ty to dec rease as the tempe rat ur es
become lower . This is because more powe r is
needed to start the vehicle and componen ts such
as the he ad lights and the rear window defogger
are used more frequent ly.
Avoid using powe r unnecessar ily, especially in
c ity dr iv ing o r o n short trips . H ave yo ur au thor­
iz ed Audi de aler or author ized A udi Se rv ice Facili­
ty check the ba ttery capacity before the start of
winter ¢
page 210. A well-charged battery will
not only reduce starting problems in co ld weath­
er, but it will a lso last longer .

Tires and wheel s
-Always adapt your driving to the road and
traff ic conditions. Dr ive carefully and red uce
yo ur speed on icy or slippery roads. Even
winter tires can lose tract io n on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow a nd ice. Summer
tires cause less road noise, tire wear and fuel
consumptio n.
(D Tips
You can also use all season tires instead of
w inte r tires. Please note that in some coun­
t ries w here winter tires are requ ired, on ly win­
t er tire s wi th the .& symbol may be pe rm it­
t ed.
Snow chains
Snow chains improve traction in the snow .
.,. Only install snow chains on the front wheels.
Th is applies also to veh icles with all wheel
drive* .
.,. Ch eck and correct the seating of th e snow
c h ains if necessa ry afte r dri ving a few feet. Fo l­
l ow the ins tructions from the manuf acturer.
.,. Note t he max imum permit ted speed w hen driv ­
ing with snow chains . Do not exceed 30 mph
(SO km/h).
Snow chains not only improve the
driving in win ­
ter road conditions, but a lso t he
braking .
Use of s now chai ns is o nly pe rm itted with certa in
r im/t ire comb ina tion s due to techn ica l reason s.
Chec k w ith an au thori zed A udi d ealer or au tho r­
ized A udi Service Facility to see if yo u may use
snow cha ins.
Use
fine -mesh snow chain s. They mus t not add
mo re th an 0 .5 3 inch ( 13.S mm) in height, in clu d­
ing the chain lock.
You must remove the chai ns when dr iv ing on
roads tha t are
free of snow. W hen r oads are free
of snow, snow chains can imp air handling an d
230
'
damage the tires, and the chains wi ll quick ly be
dest royed.
A WARNING
Using incorrect snow chains o r insta lling snow
cha ins incor rectly can res ult in loss of veh icle
c o ntrol, which increases the risk of an acc i­
dent.
(D Note
- Snow chains can damage the rims/wheel
cove rs* if the c hains come into direct c on­
tact with them. Remove the wheel covers*
first . Use coa ted snow cha ins.
Low aspect ratio tires
Your A udi is fac to ry-eq uipped w ith low aspect ra­
t io t ires. These t ires have been thoroug hly tes ted
a nd been sele cted specifi ca lly f or your mode l for
the ir su perb pe rformance, r oad fee l and h andlin g
u nder a var iety of dr iv ing con ditions. As k your au ­
t h orized Aud i dea le r fo r more details .
The low aspe ct ratio of these tires is ind icated by
a n umer al of
55 or less in the t ire's s ize design a­
tion . The nume ral represents the ratio of the
ti re's si dewall height in relatio n to its tread width
expressed i n pe rcentage. Conventional tires have
a height/width rat io o f 60 o r more .
The performance of low-aspect-ratio tire s is par­
ticularly sensitive to imprope r inflation pres­
sure. It is therefore important that low aspect ratio tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained. Tire pressures should be checked at least once a month and always
b efor e a long trip
Q page 224 .
What you can do to avoid tire and rim
damage
Low aspect rat io tires can be damaged mo re eas i­
l y by impact w ith potho les, c urbs , g ull ies o r
r idges on t he road, pa rti cularly if th e tire is un ­
der i nflated.

Emergency assistance
-When mounting tires with unidirectional
tread design
make sure the tread pattern is
pointed the right way¢
page 245 .
-The wheel bolts shou ld be clean and easy to
t ur n. Check for dirt and corrosion on the
mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be­
fore remounting the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the
right direction .
U sing a spare tire with a tread pattern
intended for use in a specific direction
When using a spare t ire with a tread pattern in­
tended for use in a specific direction, please note
the following:
- The direct ion of rotation is marked by an arrow
on the side of the tire.
- If the spare tire has to be insta lled in the incor­
rect direction, use the spare tire only tempora­
r ily since the tire w ill not be able to achieve its
optimum performance characteristics with re­
gard to aquaplaning, noise and wear .
- We recommend that you pay part icular atten­
tion to th is fact during wet weather and that
you adjust your speed to match road condi­
tions.
- Replace the flat tire with a new one and have it
installed on your veh icle as soon as possible to
restore the handling advantages of a unidirec­
tional tire.
Notes on wheel changing
Please read the information ¢ page 221 if you
are going to use a spare tire which is different
from the tires on your vehicle.
After yo u change a tire:
-Check the tire pressure on the spare immedi-
ately after installation.
