range of
O mi (0 km) was displayed in the
instrument cluster, switch the ignition on
for about 15 seconds before starting the en­ gine.
_& WARNING
Ad Blue can irritate the skin, eyes and res­piratory 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 di­lute it with water .
- Do not add Ad Blue to the diesel tank or
add diesel fuel to the Ad Blue tank. Mix­
ing can lead to damage to the engine
and the Ad Blue tank system. Warranty
does not cover damage caused by this.
- AdBlue attacks surfaces such as painted
vehicle components, plastic and carpet.
Remove the fluid as quickly as possible
with a damp cloth and plenty of cold wa­
ter. If the Ad Blue has already crystal­ lized, use warm water and a sponge .
AdBlue residue that is not removed will
crystallize and can damage the affected
surface .
- Do not store the refill bottle in the vehi­ cle. If it leaks, the escaping Ad Blue could
damage the vehicle interior.
- Do not allow AdBlue to come into con­
tact with clothing . If there is contact
with the fluid, flush immediately with
plenty of water.
@ Tips
- You can obtain refill bottles from an au­
thorized Audi dealer or authorized Audi
Service Facility.
- Follow the AdBlue manufacturer's in­
structions for use and storage.
Checking and Filling 217
Hood
Working in the engine compartment
Special care is required if you are working in
the engine compartment
For work in the engine compartment such as
checking and filling fluids, there is a risk of
injury, scalding, accidents, and burns. For
this reason, follow all the following listed
warnings and general safety precautions.
The engine compartment is a dangerous
area.
c::> .&. .
_8 WARNING
To reduce the risk of injuries, complete the
following steps before opening the hood:
- Turn the engine off.
- Switch the ignition off.
- Set the parking brake.
- Place the selector lever in the P position.
- Let the engine cool down.
- Never open the hood when you see that
steam or coolant drips from the engine
compartment- there is a danger of burns! Wait until no steam or coolant
flows out .
- Keep children away from the engine com­
partment.
- Never spill fluids on a hot engine . These
fluids (such as the freeze protection con­
tained in the coolant) can catch fire .
- Avoid short circuits in the electrical sys­
tem, especially the battery .
- When working in the engine compart­
ment, remember that the radiator fan
can switch on even if the ignition is
switched off, which increases the risk of
personal injury.
- Never open the cap on the coolant ex­
pansion tank when the engine is warm.
The cooling system is under pressure.
- To protect your face, hands, and arms
from hot steam or coolant, cover the cap
with a large cloth when opening.

218 Check ing and F illin g
- Do not remove the engine cover under
any circumstances. Th is increases the
risk of burns.
- If tests need to be performed with the
engine running, there is additional dan­
ger due to moving components (such as
the ribbed belt, generator and radiator
fan) and from the high voltage ign ition
system .
- Never reach into the rad iator fan . The
electric auxiliary fan is controlled by
tempe ratu re and can sw itch on suddenly.
- Pay attention to the following warn ings
listed wh en work on the fue l system or
on the electrical equipment is required.
- Always disconnect the vehicle battery
from the vehicle electrical system
- Do not smoke
- Never work near open flames
- Always have a working fire extinguisher
nearby
- To reduce the r isk of electric sho ck a nd
injury, never touch the following compo­
nents when the engine is running or is
being started:
- Ignition cable
- Other components in the electronic
h igh voltage ignition system
- If you must check or perform work on
the engine while it is running:
- Set the parking brake and place these­
lector lever in the P (park) posit ion
first.
- Always proceed with ext reme caut ion
so that clothing, jewelry or long hair do not become ca ugh t in the radiator fan,
fan belt o r other moving components
or do not come into contact with hot
components . Tie back long hair before
beginning work and do not wear cloth­
ing that can hang down into the en­
g ine.
- Limit your exposure to exhaust and
chemica ls to as short a time as poss ible
~ .&. -
A WARNING
Ca lifornia Proposition 6S Warning:
- Engine exhaust, some of its constituents,
and certain vehicle components contain
or emit chemicals known to the State of
California to cause cancer and birth de­
fects and reproductive harm. In addition,
certa in flu ids contained i n veh icles and
certain products o f componen t wear con­
tain or emit chemic als known to t he
State of California to ca use cancer and
birth defects or other reproductive ha rm .
- Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive harms. Wash hands after handling.
(D Note
When filling fluids, be sure not to mix the
fl ui ds up . Otherwise severe ma lf u nctions
and engine damage w ill occur.
@ For the sake of the environment
You sho uld reg ularly chec k the ground un­
der your vehicle in order to detect leaks
quick ly. If there are visib le spots from oil
or other fluids, br ing your vehicle to an au­
thorized Audi dealer or qua lified repair fa­
cility to be checked .

226 Checking and Fill in g
- Do not add any type of radiator leak sea l­
ant to your ve hicle's engine coolant.
Adding rad iator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in damage not covered by your New Vehicle
Limited Warranty.
Adding coolant
Fig . 164 Engine co mpa rtment: mark in gs on the coo l­
ant expans ion tank
R ea d a nd f ollow ing th e W ARNING S before
checking anything in the eng ine compartment
¢ page 217.
Ch eck ing t he e ngi ne coolant level
"Park your vehicle on a level surface .
.. Switch the ign ition off .
" Read the coo lant level on the coolant expan­
s ion tank ¢
fig. 164. The coo lant level must
be between the markings when the eng ine
in cold. When the engine is warm it can be
sl ightly above the upper marking .
Adding coolan t
Requirement : There must be a residual
amount of coolant in the expansion tank ¢(D .
.. Let the engine cool down.
" Place a cloth over the coolant expansion
tank cap and unscrew the cap counterclock­
wise ¢&_ .
.. Add coolant mixed in the correct ratio
¢ page 225 up to the upper marking.
.. Make sure that the fluid level remains sta­
ble. Add more coolant if necessary.
" Clove the cap securely. A coolant loss suggests a
leak. Immediately
drive your vehicle to an authorized repair fa­
c ility and have the cooling system inspected.
If the cooling system is not leaking, a loss can
come from the coolant boiling through over­
heating and being pushed out of the cooling
system.
A WARNING
The cooling system is press urized and can
become very hot. To reduce the r isk of
b urns from hot coolant:
- Do not open the coolant expansion tank
cap with the engine ho t. T here is a risk of
burns.
- Stop the eng ine and a llow it to cool.
- Protect your face, hands and arms from
escaping coolant and steam by covering
the coolant tan k cap with a large, th ick
cloth.
- Turn the coolan t tank cap counterclock­
wise 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
exhaust system or hot engine compo ­
nents. The ethy lene g lycol in engine
coo lant can catch fire under certain cir­
cumstances.
- The coolant additive and the coolant can
be dangerous to your health . For this
reason, keep the coo lant in the origina l
container away from ch ildren . There is a
risk of poisoning.
- When working in the engine compart­
ment, remember that the rad iator fan
can switch on even if the ignition is
sw itched off, which increases the risk of
pe rsonal injury.
(D Note
Do not add coolant if the expansion tank is
empty . Air could enter the cooling system
and damage the eng ine .
If this is the case,
do no t continue dr iving. See a n author ized

Radiator fan
The radiator fan switches on automatically by
itself
An auxiliary electric radiator fan switches on
and off depending on coolan t temperature
and other vehicle operating conditions .
After you switch the engine off, the auxiliary
fan can continue running for up to 10 minutes
- even with the ignition off. It can even switch
on again later by itself<=>.& , if
- the temperature of the engine coolant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
A WARNING
-To reduce the risk of personal injury nev­
er touch the radiator fan.
- The auxiliary electric fan is temperature
controlled and can switch on suddenly
even when the engine is not running.
- The auxiliary radiator fan switches on au­
tomatically when the engine coolant
reaches a certain temperature and will
continue to run until the coolant temper­
ature drops.

Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS r::;, page 217 .
Checking and Filling 22 7
.. Read the brake fluid level from the brake
fluid reservoir <=>
fig. 165, <=> page 220,
fig. 159.
T he brake fluid level must be be­
tween the "MIN" and "MAX" markings.
The location of the brake fluid reservoir can be seen in the engine compartment illustration
<=>page 220.
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 be­
low the "MIN" mark, the brake warning/indi­
cator light . (U.S. models)
I. (Canadian
models) will come on
c:> page 18 . Do not con­
tinue to operate the vehicle. The complete
brake system should be thoroughly checked
by an authorized Audi dealer or other quali­
fied facility and the cause corrected . If the
brake fluid level is too low, the brake warning/
indicator light will illuminate. Contact an au­
thorized Audi dealer
immediately.
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician.
Brake fluid absorbs moisture from the air . If
the water content in the brake fluid is too
high, corrosion in the brake system may result
after a period 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 conforms 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 author­
ized
Audi dealer. Your dealer has the correct
tools, the right brake fluid and the know-how
to do this for you.

230 Checking and Filling
-Do not expose the battery to an open
flame, electric sparks or an open light.
- Do not smoke.
- Do not interchange the positive and neg-
ative cables.
- When working on the battery, be sure
not to short-circuit the terminals with
tools or other metal objects. This would
cause the battery to heat up very quickly,
which could lead to damage or explosion
and personal injury.
- When a battery is charged, it produces
hydrogen gas which is explosive and
could cause personal injury.
- Always keep the battery well out of the
reach of children.
- Before work is done on the electrical sys­
tem, disconnect the negative ground ca­ ble.
- Before performing any work on the elec­
trical system, switch off the engine and ignition as well as any electrical equip ­
ment . The negative cable on the battery
must be disconnected . If you are just go­
ing to replace a light bulb, then it is
enough to switch off the lights.
- Before disconnecting the battery, switch
off the anti-theft alarm system! Other­
wise you will set off the alarm.
- When disconnecting the battery, first
disconnect the negative cable and then
the positive cable .
- Before reconnecting the battery, make
sure all electrical consumers are switch­
ed off. Reconnect the positive cable first
and then the negative cable. Never inter­
change the cables -this could start a fire!
- Never charge a frozen or a thawed-out
battery. It could explode! If a battery has
frozen, then it must be replaced. A dead battery can free ze over at 32°F (O°C).
- Make sure the vent hose is always attach­
ed to the opening on the side of the bat­
tery.
- Never use batteries which are damaged.
There is the danger of an explosion! Al­
ways replace a damaged battery . A WARNING
-California Proposition 65 Warning:
- Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive problems . Wash hands after han­
dling.
(D Note
- Do not disconnect the vehicle battery
when the ignition is on or when the en ­
gine is running, otherwise, you will dam­
age electronic components in the electri­
cal system.
- If your vehicle is going to stand for a
long period of time without being driven,
protect the battery from "freezing", oth­
erwise it will be damaged and will then
have to be replaced.
Battery charging
Starting the engine requires a well charged
battery.

TPMS low tire pressure telltale.
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indica te when
the system is not operating properly . The
TPMS malfunction indicator is combined with
the low tire pressure tellta le . When the sys­
tem detects a malfunct ion, the telltale will
flash for approximately one minute and then
remain cont inuous ly illuminated. This se ­
quence will continue upon subsequent vehicle
start-ups as long as the ma lfunction ex ists .
When the malfunct ion indicator is illuminat­
ed, the system may not be able to detect or
sig nal low t ire pressure as intended . TPMS
malfunct ions may occur for a variety of rea­
sons, including the installa tio n of replace­
ment or a lternate tires or whee ls on the veh i­
cle that prevent the TPMS from funct ion ing
properly. Always check the TPMS malfunction
tellta le after replacing one or more tires or
wheels on your veh icle to ensure that the re­
placement or alternate tires and wheels allow
the
TPMS to continue to function properly.

266 Tire s and wheels
& WARNING
-If the tire pressure warning light ti] in
the instrument cluster turns on, the
pressure in one or more tires is too low.
Reduce the vehicle speed immediately
and avoid any hard steering or braking
maneuvers . Stop as soon as possible,
check the t ire and inflate the tire to the
correct pressure, which is specified on
the tire pressu re label on the veh icle
¢ page 240. Driving with a t ire with low
pressure causes the tire to overheat and
can result in failure of the tire . Low pres ­
sure can a lso have a negative effect on
the driving and braking behavior of the
vehicle.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the t ire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor ind i­
cator may be delayed .
- Ask your author ized dealer if run-flat
t ires may be used on your vehicle.
- The tire pressure monitoring system can
also stop work ing when there is an ESC
malfunction.
- Using snow chains may result in a system
malfunction.
- The tires with the identification "AO" or
"RO" ¢ page 254 have been matched
with your Audi tire pressure monitoring
system. We recommend that you use
these tires.
- The tire pressure monitoring system can
only mon itor the t ire pressure of the
driving tires . Check the tire pressure of
the spare wheel in the luggage compart­ ment so that if necessary it is ready for
us e.

29 0 Con sum er Inf ormation
comp lexity of today's automobi les, have
steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners.
Also, s afety an d e nvir onm ent al con­
cerns place very strict limits on the nature of
repairs and adjustments to engine and trans ­
miss ion pa rts which an owner can perform .
Maintenance, adjustments and repa irs usua lly
require special tools, testing devices and oth­
er equipment avai lab le to specially trained
workshop personnel in order to assure proper
performance, reliab ility and safety of the vehi­
cle and its many systems .
Improper ma intenance, adjustments and re ­
pa irs can impair the operation and reliab ility
of your vehicle and even void your vehicle war­ ranty. Therefo re , proof of servic ing in accord­
ance w it h the ma intenance sched ule may be a
condition for upholding a poss ible warranty
claim made within the warran ty period.
Above all, operational safety can be adve rsely
affected, creating unnecessary risks for you
and your passengers.
If in doubt about any serv icing, have it done
by your author ized Audi dealer or any other
p roperly equipped and qualified workshop .
We strong ly urge you to give your authorized
Audi dealer the opportunity to perform all
schedu led maintenance and necessary repairs .
Your dea ler has the facilities, or iginal parts
and tra ined spec ialists to keep your vehicle
running properly .
Performing lim it e d m aint en anc e y ourself
The fo llowing pages describe a limited num­
ber of procedures which can be performed on
you r vehicle with ordinary too ls, shou ld the
need arise and trained personnel be unavaila­
ble. Before performing any of these proce­
dures, always thoroughly read all of the app li­
cable text and ca refully follow the instruc­
tions given. Always rigorously obse rve the
WARNINGS p rovided .
Before you ch eck anything in th e engin e
compartme nt, alway s read an d heed all
WARNINGS ~
& and ~page 217 .
_& WARNING
-Ser ious personal injury may occur as a re­
sult of improperly performed mainte­
nance, adjustments or repa irs .
- Always be extremely careful when work­
ing on the vehicle . Always follow com­
monly accepted safety pract ices and gen­
eral common sense. Never r is k personal
in ju ry.
- Do not attempt any of the maintenance ,
checks or repairs descr ibed on the fol­
lowing pages if you are not fu lly fam iliar
with these or other procedures with re­
spect to the vehicle, or are uncertain how
to proceed .
- Do not do any work without the proper
too ls and equipment. Have the necessa ry
work done by your author ized A udi deal­
er or another proper ly equipped and
qualified workshop.
- The engine compartment of any motor
veh icle is a potentially hazardous area.
Never reach into the area around or
touch the rad iator fan. It is temperature
controlled and can sw itch on suddenly -
even when the engine is off . The radiator
fan switches on automatical ly when the
coo lant re aches a certain temperature
and will cont inue to run until the coo lant
temperature drops .
- Always sw itch off the ignition before any­
one gets under the vehicle.
- Always support your veh icle with safety
stands if it is necessary to work under­
neath the vehicle. The jack s upplied with
the vehicle is not adequate for this pu r­
