([) Note
- Before the start of winter, have an author­
ized Audi dealer or authorized Audi Service
Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate. This is especially important
when driving in colder climates.
- If the appropriate coolant additive is not
available in an emergency, do not add any
other additive. You could damage the en­
gine. If this happens, only use water and re­ store the correct mixture ratio with the
spec ified coolant additive as soon as possi­
ble.
- Only refill with new coo lant.
- Radiator sealant must not be mixed w ith
the coo lant .
Adding coolant
F ig. 181 Engine compartment: coolant expans ion tank
cover
Observe the safety precautions~ page 189,
Working in the engine compartment .
Checking the engine coolant level
• Park the vehicle on a leve l surface .
• Switch the ignition off.
• Read the coolan t leve l on the coo la nt expansion
tank~ page 192, fig . 179. The coolant level
must be between the MIN and MAX markings
196
when the engine in cold. When the engine is
warm it can be slightly above the MAX marking .
Adding coolant Requirement: there must be a residual amount of
coolan t in the expansion tan k
~CD -
• Let the engine cool down .
• Place a cloth over the coolant expansion tank
cap and unscrew the cap counterclockw ise
~ & -
... Add coo lant m ixed in the cor rect ratio
~ page 195 up to the MAX marking.
• Make sure that the fluid level remains stab le .
Add more coolant if necessary .
• Close the cap securely.
Coolant loss usually ind icates there is a leak . Im­
mediate ly drive your vehicle to an authorized
Audi dealer or authorized Audi Service Fac ility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheat ing
and being pushed out of the cooling system .
A WARNING
- The cooling system is under pressure. Do
not open the coo lant expansion ta nk cap
when the engine is hot. This increases the
risk o f bur ns.
- The coolan t addi tive and the coolant can be
dangerous to your health. For t his reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
(D Note
Do not add coolant if the expansion tank is
empty. A ir cou ld enter the cooling system and
damage the engine. If this is the case, do not
continue driving. See an authorized Audi deal­
er or authorized Audi Serv ice Facility for assis­
tance.

The winds hield washer reservoir O contains the
cleaning solution for the windshield and the
headlight washer system*
c::;,page 192 , fig . 179.
The reservoir capacity can be found in
c::;, page 245 .
To reduce the risk of lime sca le deposits on the
spray nozzles, use clean water w ith low amounts
of calc ium . Always add window cleaner to the wa­
ter . When the outs ide temperatures are cold, an
anti-freez ing agent should be added to the water
so that it does not freeze.
0 Note
- The concentration of anti-freezing agent
must be adjusted to the vehicle operating
cond itions in the respect ive climate. A con­
centration that is too high can lead to vehi­
cl e damage.
Checking and Filling
- Never add radiato r anti -freeze or other addi­
tives to the washer fluid .
- Do not use a glass cleaner that contains
paint solvents, because this could damage
the paint.
Service interval display
The service interval display detects when your ve ­
hicle is due for service .
The service interval display works in two stages:
-Inspection or oil change reminder : after a cer-
tain distance driven, a message appears in the
instrument cluster display each time the igni­
tion is switched on or off. The remaining dis­
tance or time is disp layed briefly.
-Inspection or oil change due: if your vehicle
has reached an inspection or oil change interval
or both intervals at the same time, the mes­
sage
Inspection due! or Oil change due! or Oil
change and inspection due!
appears briefly af­
ter switching the ignition on/off .
Checking service intervals
You can check the remaining distance or time un ­
til the next oi l change or next inspection in the
Car menu. To do this, select: the
I CAR I function
button

Wheels and Tires
General information
.,,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,,.Have faulty tires or rims re­
placed immediately.
.,,.Protect your tires from oil,
grease and fuel.
.,,.Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
.,,.Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
&_ WARNING -
-Never drive faster than the
maximum permitted speed
for your tires. This could cause the tires to heat up too much.
This increases the risk of an
accident because it can cause
the tire to burst.
-Always adapt your driving to the road and traffic condi-
Wheels
tions. Drive carefully and re­
duce your speed on icy or slip­
pery roads. Even winter tires
can lose traction on black ice .
@ Note
-Please note that summer and
winter tires are designed for
the conditions that are typical
in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires , which affects traction
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be
used in winter driving condi­
tions. The surface of the rims does not have sufficient corro­
sion protection for this and
could be permanently dam­
aged by road salt or similar
substances.
