Cooling system
Coolant
T he engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
quires little attention .
The cooling system has been filled at the factory
with a permanent coolant which does not need to be changed . The coolant consists of a mixture of
specially conditioned water and the manufactur ­
er's glycol-based coolant additive G13 antifreeze
with anticorrosion additives (50% for USA mod­
els · 60% for Canadian models). This mixture
'
both assures the necessary frost protection and
protects metal components in the engine 's cool­
ing system from corrosion and scaling. It also
raises the boiling point of the coolant.
Do not reduce the concentration of the coolant in
the summer by adding plain water.
The propor­
tion of coolant additive must be at least 50% but not more than 60%
to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
gine cooling system .
For year-round driving, antifree ze is added at the
factory for temperatures down to:
- -31 °F ( -3 5 °C) USA
- - 40 °F ( - 40 °C) Canada.
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled water is recommended.
_& WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN-
222
INGS ~&. in Working in the engine compart­
ment on page 216.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in your
vehicle is sufficient to meet the climate con­ ditions. This is especially important if you
live in a region where the winter is extreme­
ly cold . If necessary, increase the proportion
of coolant additive to 60%.
- When adding coolant additive to your cool­
ing system, remember:
- We recommend using only coolant addi­
tive G12++ or G13 (check the label) for
your vehicle. This coolant additive is avail­
able at authorized Audi dealers. Other
types of antifreeze can significantly re­
duce corrosion protection. The resulting
corrosion can cause a loss of coolant and
serious engine damage .
- Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Adding ra ­
diator repair fluid may adversely affect the
function and performance of your cooling
system and could result in damage not cov­
ered by your New Vehicle Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.

page 216.
.,. Read the brake fluid level from the brake fluid
reservoir
¢fig. 190, ¢page 218, fig. 186. The
brake fluid level must be between the "MIN "
and "MAX" markings.
The location of the brake fluid reservoir can be
seen in the engine compartment illustration
¢page 218.
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 below
the "MIN" mark, the brake warning/indicator
light
1111 (U.S. models) ;II (Canadian models)
will come on¢
page 14. Do not continue to oper­
ate the vehicle. The complete brake system
should be thoroughly checked by an authorized
Audi dealer or other qualified facility and the
cause corrected. If the brake fluid level is too
low, the brake warning/indicator light will illumi ­
nate. Contact an authorized Audi dealer
immedi­
ately.
Checking and Filling
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs moisture from the air. If the
water content in the brake fluid is too high, cor­
rosion in the brake system may result after ape ­
riod 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 con­
forms 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 authorized
Audi
dealer. Your dealer has the correct tools, the
right brake fluid and the know-how to do this for
you.
A WARNING
- Brake fluid is poisonous. It must be stored
only in the closed original container out of
the reach of children!
- Brake failure can result from old or inappro­
priate brake fluid . Observe these precau­
tions:
- Use only brake fluid that meets SAE speci­
fication
J 1703 and conforms to Federal
Motor Vehicle Standard 116. Always check
with your authorized Audi dealer to make
sure you are using the correct brake fluid.
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 seriously affect the efficiency of
the brakes as well as your safety. This
could result in an accident.
(D Note
Brake fluid will damage the paint of your vehi-
cle.

New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au­
thorized repair facility . These fa ­
cilities have the proper knowl­
edge and are equipped with the
required tools and replacement
parts.
.,. New tires do not yet have the
optimum adhesion properties .
Drive carefully and at moderate
speeds for the first 350 miles (500 km) with new tires .
.,. Use tires of the same construc­
tion, size (rolling circumference)
and as close to the same tread pattern as poss ible on all four
wheels .
238
.,.Do not replace tires individually .
At least replace both tires on the
same axle at the same time.
.,. Audi recommends that you use
Audi Original equipment tires . If
you would like to use d ifferent
tires, please note that the tires may perform differently even if
they are the same size ¢
,&.
.,. If you would like to equip your
vehicle with a tire/rim combina ­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi dealer or authorized repair facili­
ty before making a purchase
~ & -
The spare tire* is different from
the regular tires installed on the
vehicle -for example, if winter
tires or wide tires are installed -
then only use the spare tire* tem­
porarily in case of emergency and
drive carefully while it is in use. It
should be replaced with a regular
tire as soon as possible.
On
all wheel drive vehicles, all
four wheels must be equipped
with tires that are the same brand and have the same construction
and tread pattern so tha t the
drive system is not damaged by

~ Check and correc t the seating of the snow
chains if necessary after driving a few feet. Fol­
l ow the instructions from the manufacturer .
~ Note the maximum permitted speed when driv­
ing with snow chains. Do not exceed 30 mph
(SO km/h) .
Snow chains not only improve the
driving in win­
ter road cond itions, but also the
braking.
Use of snow chains is on ly permitted with certain
rim/tire combinations due to tec hnical reasons .
Check with an authorized Audi dealer or author­ ized repair facility to see if you may use snow
cha ins.
You must remove the chains when driving on roads that are
free of snow. When roads are free
of snow, snow chains can impair handling and
damage the t ires, and the chains w ill quickly be
destroyed .
A WARNING
Using incorrect snow chains o r installing snow
chains incorrect ly can result in loss of vehicle
c ont rol, w hic h in cr eases the risk of a n acci ­
de nt.
- Snow cha ins can damage the rims/wheel
covers* if the cha ins come into d irect con­
tact wi th them . Remove the whee l cove rs*
first. Use coated snow cha ins.
- Usi ng snow chai ns tha t add more than 0.4
i nch (10.5 mm) of he igh t ca n severely dam­
age the wheel ho usings and othe r vehicle
components .
- Do no t install and use s now chains if there is
a mal funct ion in the adaptive air suspen ­
sion*, because the vehicle height wi ll be
very low. If you d rive with snow chains any­
way, the wheel ho usings and othe r vehicle
components can be severely damaged.
Low aspect ratio tires
Your Aud i is factory -equipped with low aspect ra­
tio tires . These t ires have been tho rough ly tested
and been se lected specifically for yo ur model fo r
Wheel s
their superb performance, road fee l and handling
u nder a variety of driving conditions . Ask your au­
thorized Audi dea le r fo r more detai ls.
T he low aspect rat io o f th ese tires is indicated by
a n umeral of
55 or le ss in the tire's size des igna­
tion . The numera l represents the ratio of the
t ir e's s idewall height in relation to its tread w idth
expressed in percentage. Conventiona l tires have
a he ight/width ratio of 60 or more.
The performance of low-aspect- ratio tires is par­
ticularly sen sitive to imprope r inflat ion pres­
s ure. It is the refore important that low aspect
rat io tires are inflated to the speci fied pre ssure
and that the inflation pressure i s regularly
checked and m aintain ed. Tir e pr essures should
be checked at least once a month and always
b efor e a long trip
~ page 241.
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged more eas i­
ly by impact w ith po tholes, curbs, gullies or
ridges on the road, particularly if the tire is un ­
deri nflated.
In orde r to m in imize the occurrence of impact
damage to t he tires of yo ur vehicle , we recom ­
me nd that you observe the following pre ca u­
t ions:
- Always ma intain recommended inflat ion pres­
sures. Check yo ur tir e pressure every 2,000
m iles (3 ,00 0 k m) and add air if necessary.
- Dr ive ca refully on roads w it h potholes, deep
gullies o r ridges. T he impact from dr iving
t hrough or over such obstacles can damage
your tires. Impac t wi th a curb may a lso ca use
damage to your tires.
- Afte r any impac t, immed iate ly inspect yo ur
t ires or have them inspected by the nearest au ­
thorized A udi dealer. Rep lace a damaged tire as
soon as possible.
- Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear. Damage is not a lways
easy to see. Damage can lead to loss of air and
underinflation, wh ich could eventually cause
tire fa ilure. If you believe that a tire may have
been damaged, replace the tire as soon as pos -
sible . .,.

-The spare tire is intended on ly for tempora­
ry and short-term use. It shou ld be replaced
as soon as possible with the normal wheel
and t ire.
- After mounting the compact spare tire, the
tire pressure must be checked as soon as
poss ible. The t ire pressure of the compact
spare tire m ust be 4.2 bar; otherwise, you
risk having an accident.
- Do not drive faster than SO mph (80 km/h).
You risk hav ing an accident .
-Avoid full-throttle accelerat ion, heavy brak­
ing, and fast cornering . You risk having an
acc ident.
- Never drive us ing more than one spare
wheel and tire . You risk having an acc ident.
- Normal summer or winter tires must not be
mounted on the compact spare wheel rim .
- For technical reasons, the use of tire chains
on the spare tire is not perm itted. If it is
necessary to drive with t ire chains, the spare
wheel m ust be mounted on the front axle i n
the even t of a flat in a rea r tire. The new ly
avail able front wheel m ust then be insta lled
in place of the rear wheel with the flat tire .
Installing the tire chain before mounting
the wheel and tire is recommended .
- Loose items in the passenger compartment
can cause ser ious personal injury during
hard braking or in an acc ident. Never store
the inflatable spare t ire or jack and too ls in
the passenger compartment.
