gine .
.&_ WARNING
Ad Blue can irritate the skin, eyes and res­
piratory system. If there is contact with
the fluid, flush immediately with plenty of
water . Consult a physician if necessary .
(D Note
-Only use Ad Blue that conforms to the
standard ISO 22241-1. Do not mix any
additives with the Ad Blue and do not di­
lute it with water .
- Ad Blue is not a diesel additive. Do not
add it to the diesel tank. If Ad Blue is
mixed w ith diesel fuel, it can lead to
damage to the eng ine and the Ad Blue
tank system . The Limited New Vehicle
Warranty does not cover such damage.
- AdBlue attacks surfaces such as painted
vehicle components, plast ic and carpet.
Remove the fluid as quick ly as possible
with a damp cloth and plenty of cold wa­
ter . If the AdBlue has already crystal­
lized, use warm water and a sponge.
AdBlue residue that is not removed w ill
crystall ize and can damage the affected
surface .

Coolant loss
Coolant loss may indicate a leak in the cooling
system . In the event of coolant loss, the cool­
ing 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 result of overheating.
A WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing 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 ap­
plying 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.
(D Note
Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant. Add­
ing radiator repair fluid may adversely af­
fect the function and performance of your
cooling system and could result in damage
not covered by your New Vehicle Limited
Warranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS c:;, A in Working in the engine compart­
ment on page 264.
Checking and filling 273
.. Turn off the engine .
.. Let the engine cool down.
.. Place a thick rag over the coolant expansion
tank
c:;, page 2 72, fig. 247 and carefully
twist the cap counter-clockwise c:;, &, .
.. Add coolant .
.. Twist the cap on again
tightly.
Replacement engine coolant must conform to
exact specificat ions
c:;, page 2 71, Coolant. We
recommend using only coolant additive G12+
+, G13 or in an emergency G12 +. Do
not use a
different additive. In an emergency use plain
water until you can get the correct additive
and can restore the correct ratio. This should
be done as soon as possible.
If you have lost a considerable amount of
coolant, 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. Ex­
cess coolant will be forced out through the
pressure relief valve in the cap when the en ­
gine becomes hot.
A 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 an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certain
conditions, the ethylene glycol in en­
gine coolant can catch fire.
- Antifreeze is poisonous. Always store an­
tifreeze in its original container and well
out of the reach of children. .,.

e lectrical system when absolutely necessary
for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a pe riod
of several days or weeks, electrical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and main ­
tains starting capab ility over a longer period
<=> page 231.
Take into consideration that when you un lock
your vehicle, some convenience functions, such as the interior lights or the power seat
adjustment, may not be available. The con­
venience functions will be available again
when you turn on the ignition and start the
engine .
Winter operation
During the winter months, battery capacity
tends to decrease as temperatures drop . This
is because more power is also consumed while
starting, and the headlights, rear window de ­
fogger, etc., are used more often .
Avoid unnecessary power consumption, par­
ticularly in city traffic or when traveling only
short d istances . Let your authorized Audi
dealer check the capacity of the vehicle bat­
tery before w inte r sets in
<=> page 277. A well
cha rged battery w ill not only prevent starting
p rob lems when the weather is cold, but will
a lso last longer.
(D Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the
vehicle battery should be removed and
stored where it will not freeze . This wi ll
prevent it from being damaged and having
to be replaced.

tire inflatio n pressures for the vehicle at its
maximum capacity we ight a nd the tires that
were on your vehicle at the time it was man ­
ufactured . For recommended t ire pressures
for normal load condit ions, please see chap ­
ter ~
page 284 .
-Turn the valve stem cap counter-clockwise
to remove it from the tire valve .
- Place the air pressure gauge on the valve.
- The tire pressures should only be checked
and adjusted when the tires are cold . The
s light ly raised pressures of warm tires must
not be reduced .
- Adjust the tire pressure to the load you are
carrying.
- Re insta ll the va lve stem cap on the valve .
When should I check the tire pressure ?
The correct tire pressure is especially impor ­
tant at high speeds . The pressure sho uld
therefo re be checked at least once a month
and a lways before start ing a journey. Do not
forget to check the tire pressure for the spare
wheel.
When should I adju st the tire pre ssures?
Ad just the tire pressure to the load you are
carrying. After changing a wheel
or replacing
wheels you have to adjust the tire pressures
on all wheels. In addition, you must then
store the new tire pressures i n the t ire pres­
sure mon itor ing system
~ page 300.
A WARNING
Incorrect tire pressures and/or unde rinfla­
tion ca n lead sudden tire failure, loss of
cont ro l, col lision, ser ious persona l inju ry
or even death.
- Whe n the wa rning symbo l
[ti] appears in
the instrume nt cl uster, s top and inspect
the tires.
- Incorrect tire pressure and/or underinfl a­
t ion can ca use inc reased t ire wear and
can affect the handling o f the veh icle and

- The driver is responsi ble for the co rrect
tire pressures for all tires on the veh icle.
The applicable pressure values are locat­
ed on a sticker o n the dr iver's s ide B-pil­
lar .
- Onl y when all tires on the vehicle are fil­
led to the correct pressure, the t ire pres­
sure mon itor ing system can work cor­
rectly .
- The use of incorrect tire pressure va lues
can lead to acc idents or other damage .
Therefore it is ess ential that th e drive r
observe t he spec ified t ire p ress ure val ues
for the tires and the cor rect pressures for
the func tion of the t i re p ress ure moni to r­
ing system.
- Always in flate tires to the recommen ded
a nd correct t ire p ress ure be fore dr iv ing

- D riving with unde rinf lated tires bend
mo re, letting them get too hot resulting
in tread separation, s udden tire failure
and loss of control.
- Excessive speed and/overloading can
cause heat b uild- up, sudden tire failure
and loss of control.
- If the tire pressure is too low or too high,
the t ires will wear premat urely and the
veh icle w ill not handle well.
- If the tire is not flat and you do not have
to change a wheel immediately, d rive at
red uced speed to the nearest service sta­
tion to check the t ire press ure and add
air as requ ired .
(D Note
Driving w ithout valve stem caps can cause
damage to the tire valves. To prevent this,
a lways make sure that factory installed
valve s tem caps o n all whee ls are sec urely
mounted o n the valve .

Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of whee l bolts is matched to the
factory insta lled r ims. If different rims are fit­
t e d, the cor rect wheel bolts wit h the right
lengt h and correctly s haped bolt heads must
be used. This ens ures t hat w heels a re fitted

I n ce rtain circumstances, you may not use
wheel bo lts from a d ifferent vehicle -even if it
is the s ame mode l
~page 32 7.
& WARNING
Improperly tig htened or maintained whee l
bolts can become loose ca using loss of
cont ro l, a co llision and serious persona l in­
jury.
- Always keep the w heel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­ erly t ightened.
- Never grease or oil the wheel bolts and the threads in the wheel hubs. They can
become loose w hile driving if greased or
o iled, even if tig hte ned to the specified
torq ue.
Tire s an d wheel s 297
-On ly use whee l bolts that be long to the
rim being installed.
- Never use different wheels bolts on yo ur
veh icle.
- Always maintain the correct t ightening
torque for the whee l bolts to reduce t he
risk o f a wheel loss. If the tightening tor­
que of t he wheel bolts is too low, they
can loosen and come out when t he vehi­
cle is mov ing.
If the tig hte ning torque is
too high, the wheel bolts and threads can be damaged and the whee l can be­
come loose.

Low aspect ratio tires
Your Audi is factory-equ ipped with tow aspect
ratio tires. These tires have been thoroughly
tested and been se lected specifically for your
model for their superb perfo rmance, road feel
and handli ng under a var iety of drivi ng condi­
tions. As k your au thori zed A udi dealer for
more de tails.
The low asp ect ratio of these tires is ind icated
by a nu mera l of
55 or l ess in the tire's s ize
designation. The n ume ra l rep resen ts the ra tio
of the tire's sidew all height in rel ation to its
tread width exp ressed in percentage . Conven ­
tiona l tires have a he ight/width ratio of 60 or
more.
The performance of low-aspect-ratio tire s is
particularly sensitive to improper inflation
pre ssure. It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the inflation pressure is
regularly checked and mainta ined. Tire pres-
sures should be checked at least once a .,..
