Checking and Filling
"' Place a thick rag over th e coolant expansion
tank and
carefully turn the cap counter-clock­
wise
¢ ,& .
"'Read the engine coolant level inside the coolan t
expansion tank
¢ fig . 164, ¢page 189,
fig. 16 1.
With a cold engine , the coolant level
should be between the ' 'MIN" and "MAX " mark­
ings
¢ fig . 165 -arrows- . When the engine is
warm, the level may be slightly above the
"MAX" marking.
"'Add coolant mixed in the correct ratio, if neces­
sary ¢
page 192 . Coolant may be a maximum
of 1 mm above the MAX marking.
"' Twist the cap on again
tightly .
The location of the coolant expansion tank can be
seen in the engine compartment illustration
¢ page 189.
To obtain an accurate reading , the engine must
be switched off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System¢
page 17 will
blink until you add coolant and the level has been
restored to normal. Even though there is an elec­
tric coolant level sensor, we still recommend you
check the coolant level from time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolant loss, the cooling
system should be inspected immediately by your
authorized Audi dealer. It is not enough merely
to add coolant.
In a
sealed system, losses can occur only if the
boiling point of the coolant is exceeded as a re­
sult of overheating.
Adding coolant
Replacement engine coolant must conform to ex­
act specifications ¢
page 192, Coolant.
We recommend using only coolant additive Gl2+
+ , G l3
or in an emergency Gl2+ . Do not use a
different additive . In an emergency use plain wa­
ter until you can get the correct additive and can
194
restore the correct ratio. This should be done as
soon as possible.
If you have lost a considerable amount of cool­
ant, then you should add cold antifreeze and cold
water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Excess
coolant will be forced out through the pressure
relief valve in the cap when the engine becomes
hot.
,&_ WARNING
- The cooling system is under pressure and
can get very hot. Reduce the risk of scalding
from hot coolant by following these steps.
- Turn off the engine and allow it to cool
down .
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag .
- Turn the cap slowly and very carefully in a
counter-clockwise direction while applying
light, downward pressure on the top of
the cap .
- To avoid being burned, do not spill anti ­
freeze or coolant on the exhaust system or
hot engine parts. Under certain condi­
tions, the ethylene glycol in engine cool­
ant can catch fire.
- Antifreeze is poisonous. Always store anti­
freeze in its original container and well out
of the reach of children.
- If you drain the coolant, it must be caught
and safely stored in a proper container
clearly marked "poison".
(D Note
- 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.
- Coolant pollutes the environment and could
-
cause an engine fire. Excess coolant will be .,.

Winter tires
W inter tires sign ificantly improve t he vehicle's
h andling when drivi ng in winter condit ions. Be­
cause of the ir construction (width, compound,
tread pattern), summer t ires p rov ide less t ract ion
on ice and snow.
.. Use w in ter t ires on all four wheels.
.. Only use winter tires that are approved for your
vehicle .
" Please note that the maximum permitted
speed may be lower w it h w inter tir es ~,&. .
You r authorized Audi dea le r or a uthorized re­
pair facility can in form you about the maximum
permitted speed fo r yo ur tires.
.. Check the tire pressure after insta lling wheels
~ page 206.
The effectiveness of winte r tires is reduced great ­
l y when the tread is worn dow n to a depth of
0 .157 inch (4 mm). The characteristics of w inter
tires also decrease greatly as the tire ages, re­
gardless of the remai ning tread .
A WARNING
-Never drive faster than the maximum per ­
mitted speed for your t ires. This could cause
the tires to heat up too much . This increases
the risk of an ac cident be cause it can cause
the tire to b urst.
- Always adapt you r driv ing to the road and
t raff ic conditions. Dr ive ca refully and re duce
yo ur speed on icy or slippery roads. Even
w inter tires can lose tract ion on black ice.
@ For the sake of the environment
Reinstall summer tires at the approp riate
t ime, because they prov ide be tter h and ling
when roads a re free of snow and ice. S ummer
tires ca use less road no ise, tire wea r and fuel
consumption.

{!) Tips
You can also use a ll season tires instead of
winter tires. P lease note that in some coun­
tries where w inter tires are required, only win­
ter tires w ith the
& symbol may be permit­
ted.
Snow chains
Snow chains improve traction in the snow .
.. On ly install snow chains on the front wheels .
T his applies a lso to vehicles with a ll whee l
drive .
.. Check and correct the seating of the snow
chains if necessary after driving a few feet . Fol ­
low the instructions from the manufactu rer .
.. Note the maximum permitted speed when dr iv­
ing wit h snow chains . Do not exceed 30 mph
(SO km/h).
Snow c ha ins not only improve the
driving in w in­
te r road cond itions , but also the
braking .
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons .
Check with an authorized Audi dea ler or author­
ized repa ir fac ility to see if you may use snow
chains.
Use
fine-mesh snow chains. They must not add
more than 0 .41 inch (10 .5 mm) in he ight, includ­
i ng the cha in lock.
You must remove the chains when driving on roads that are
free of snow . When roads are free
of snow, snow cha ins can impair handl ing and
damage the tires, and the chains wi ll quickly be
dest royed.
A WARNING
Using incor re ct snow chains o r insta lli ng snow
cha ins incorrect ly can result in loss of ve hicle
control, which increases the risk of an acci­
dent .
(D Note
Snow ch ains can damage the rims/wheel cov­
ers * if the chains come into direct contact

Bulbs
Replacing bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you .
It is becoming increasingly more and more diffi­
cult to replace vehicle light bulbs since in many
cases , other parts of the car must first be re­
moved before you are ab le to get to the bulb .
This applies especially to the light bulbs in the
front of you r ca r which you can only reach
through the engine compartment .
Sheet metal and bulb holders can have sharp
edges that can cause ser ious cuts, parts must be
Fuses and bulbs
correct ly taken apart and then properly put back
together to help prevent breakage of parts and
long term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend that you have
your authorized Audi dea ler replace any bulbs for
you, since your dealer has the proper tools, the
correct bulbs and the expertise.
Gas discharge lamp s (Xenon lights)*:
Due to the high electr ical voltage, have the bulbs
replaced by a qualified technician . Head lights
with Xenon light are identified by the high volt­
age sticker.
A WARNING
Changing Xenon lamps without the necessary
equipment can cause serious personal injury.
- Bulbs are pressurized and can explode when
being changed . Potential risk of injury!
- On vehicles equipped with gas discharge
bu lbs (Xenon light) * life -threatening injuries
can result from improper handling of the
high -vo ltage portions of such lamps!
-On ly your authorized Audi dealer or quali­
fied workshop shou ld change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the
bulb holders that can cause serious cuts . If
you are uncertain about what to do, have
the wor k performed by an autho rized Audi
dealer or qualified workshop. Serious per­
sonal injury may result from improperly per­
formed work .
(D Tips
-If you st ill prefer to replace the light bulbs
yourself, be aware that the eng ine compart­
ment is a hazardous area to work
inq page 187 q &..
-It is best to ask your authorized Audi dealer
whenever you want to change a bulb.
