CD Note
-Check the oil level in the Infotainment sys­
tem. If the message
II Please reduce oil
level
appears, contact an authorized Audi
dealer or authorized Audi Service Fac ility to
have excess oil extracted if necessary.
- Do not mix any additional lubricants into
the engine o il. Damage caused by such addi­
tives is not covered by the warranty .
@ For the sake of the environment
-Oil should never enter the sewer system or
come into contact with the ground.
- Pay attention to legal requirements when
dispos ing of empty oil containers.
Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta­
tion.
Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS c> A
in Working in the engine compartment on
page 304 .
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
nance booklet. This is very important because the
lubricating properties of oil diminish gradually
during normal vehicle use.
Under some circumstances the engine oil should
be changed more frequently . Change oil more of­
ten if you drive mostly short distances, operate
the vehicle in dusty areas or under predominantly
stop-and-go traffic cond it ions, or have your vehi­
cle whe re temperatures remain below freezing
for extended pe riods.
Detergent additives in the oil will make fresh oil
look dark after the engine has been running for a
short time. This is no rmal and is not a reason to
change the oil more often than recommended.
Because of the problem of proper disposal, along
with the special tools and necessary expertise re­
qu ired, we strong ly recommend that you have
Checking and Filling
your oi l changed by an authorized Audi dealer or
a qualified service station .
If you choose to change your oil yourself, please
note the following important info rmation:
A WARNING ~
To reduce the risk of persona l injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
-
-To reduce the risk of burns from hot engine
oil, let the engine cool down to the touch.
- When remov ing the oil drain plug with your
fingers, stay as far away as possible. Always
keep your forearm parallel to the ground to
help prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one large enough to hold at
least the tota l amount of oil in your engine.
- Engine oil is poisonous. Keep it well out of
the reach of children.
- Continuous contact with used engine oil is
harmful to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water.
CD Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adverse ly affect your Audi Limited New Vehi­
cle Warranty.
@ For the sake of the environment
-Before changing your oi l, first make sure
you know where you can properly dispose of
the used oil.
- Always dispose of used engine o il properly.
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle used engine o il by tak ing it to a used
eng ine oil collection fac ility in your area, or
contact a service station .

Checking and Filling
Cooling system
Coolant
The engine coo ling system is filled with a mixture
of pur ified water and coolan t addit ive at the fa c­
tory. This coo lant must not be not changed.
The coolant leve l is monito red throug h the . in­
dicator light~
page 31. Howeve r, we do recom­
mend occasionally check ing the coo lan t level
manually.
I f you must add coolant, use a m ixture of water
and coolant additive. M ixing the coolant additive
with d istilled wate r is recommended.
Coolant additive
The coolant additive is made of anti-freezing a nd
corros ion protection agents. Only use the fo llow­
ing coo lant add it ives. These additives may be
m ixed w ith each other.
Coolant additive Specification

G12++ TL 774 G
The amount of coo lant add itive that needs to be
mixed w it h water depends on the climate where
the vehicle will be operated. If the coolant addi­
tive percentage is too low, the coolant can freeze
and damage the engine.
Coolant Freeze protec-
additive tion

(D Note
- Befo re the start of winter, have your author­
i zed Audi dealer or authorized A udi Service
Fac ility check if the coolant additive in yo ur
vehicle matc hes the percentage approp riate
fo r the climate. Th is is especially important
when driving in co lde r climates.
- If the appropriate coolant additive is not
available in an emergency, do not add any
other additive. You cou ld damage the en-
310
gine . If this happens, only use water and re ­
store the correct m ixt ure ratio with the
specified coo lant add itive as soon as poss i­
ble.
- On ly ref ill with new coolant .
- Rad iator sealant mus t not be mixed wi th
the coolant.

Coolant loss usually ind icates there is a leak. Im­
med iate ly dr ive your vehicle to an author ized
Audi dealer or authorized A udi 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 overheating and being pushed out of the cooling system.
A WARNING
- The cooling system is under pressure. Do
not open the coolant expansion tank cap
when the engine is hot. This increases the
risk of burns .
- The coolant add itive and the coolant can be
dangerous to your health. For this 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. There may be a ir in the cooling sys­
tem, which increases the risk of engine dam­
age . If this is the case, do not continue driv­
ing . See an authorized Audi dealer or author­
ized Audi Service Facility for assistance.

" Read the brake fluid level from the brake fluid
reservoir
c::> fig. 250, c::> page 306, fig. 247. The
brake fluid level must be between the "MIN"
and "MAX" markings.
The brake flu id reservoir is located at the rear
partition of the engine compartment on the left
side
~ page 306 .
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/indicato r
light (USA models:
11111 , Canada models : II>
will come on c::> page 29. Do not continue to oper­
ate the vehicle. The complete brake system
should be thoroughly checked by an authorized
Audi dealer or qualified workshop and the cause
corrected . If the brake fluid level is too low, the
brake warning/indicator light will illuminate .
Contact an authorized Audi dealer
immediately .
@ Tips
The brake fluid reservoir is located under­
neath the cover.
Changing brake fluid
Hove the broke fluid changed by on 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 orig inal container out of
the reach of chi ldren!
- B rake failure can resu lt from old or inappro­
pr iate brake flu id. Observe these precau­
t ions:
- Use on ly brake fluid that mee ts SA E speci ­
fi cation) 17 0 3 and confo rms to Fede ral
Motor Ve hicle Standard 116. Always check
wit h your authorized Audi dealer to make
sure you are using the correct brake fluid.
The cor rect type o f brake fluid is a lso 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 flu id is left in the system too long.
This ca n ser iously affect t he efficiency of
the bra kes as well as your safety. This
could result in an acc ident.

Battery
General information
Unde r normal operating conditions, the battery
i n your Audi does not need any maintenance.
W ith
high outs ide temperat ures o r long da ily
d rives we recommend that you have the electro­
lyte leve l checked by an a uth orized Audi dea le r or
qua lified wor kshop. The e lectroly te leve l should
a lso be checked each time the batte ry is ch a rged
¢ page 314.

Have t he battery chec ke d when yo u take yo ur ve ­
hicle in for service . You are we ll advised to re­
place a battery that is o lder than 5 yea rs .
With ce rta in types o f airbag deployment, t he
b atte ry is disconnected from the veh icle elect ri­
ca l system for safety reasons ¢.&
in Repair, care
and disposal of the airbags on page 268.
Disconnecting the battery terminals
Some ve hicl e fu nctions (power window regula ­
tors, for examp le) are lost if the batte ry te rm i­
nals a re disconnected . These f unc tions have to be
relearned after the battery term inals are con­
nected again . To p revent this, the battery should
o nl y be disconnected from the vehicle electrical
system when absolute ly necessary for repairs.
Vehicles not driven for long periods
If you do not d rive yo ur vehicle ove r a period of
severa l days o r weeks, electr ica l components are
grad ua lly cut back or switched of f. T his reduces
energy consumpt ion and maintains start ing ca­
pability over a longer period ¢
page 138.
Some of the convenience functions may not oper­
ate, such as the inter ior lights or the power seat
adjustment . The convenience functions will be
available again w hen you turn on the ignit io n and
start the eng ine .
Winter operation
Dur ing the winte r months, battery capacity tends
to decrease as tempe ratures drop. This is be ­
ca use more power is also consumed while start­
i ng, and t he headlights, rear w indow defogger,
etc ., are used more often.
Avo id unnecessary powe r consumption, partic u­
l a rly in city traffic or when traveling o nly short
distances . Let your author ized Audi dealer check
the capacity of the vehicle battery before win ter
sets in ¢

- Following the se rvice interva ls is cr itical to
ma inta ining the se rvice l ife and val ue of
yo ur vehicle, especially the engine. Even if
the mileage on the vehi cle is low, do not ex ­
ceed the time for the next service .
- Calc ulat ing the time to the next oil change
is interrupted when the vehicle battery is
disconnected.
If the vehicle is not driven for
a long period of time, check the mainte­
nance schedule so that you can fo llow the
maintenance intervals .

Wheels
-The tire must flex more if the tire pressure is too low or if
the vehicle speed or load are
too high . This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in­ creases tire wear and has a
negative effect on driving and
braking behavior, which in­
creases the risk of an accident.
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
Tire pressure table
Please note that the information
contained in the following table
was correct at the time of print­
ing, and the information is sub­
ject to change. If there are differ­
ences between this information
and the tire pressures specified
on the label on the driver's side 8-pillar, always follow the specifica­
tion on the 8-pillar label
¢ page 327, fig. 255.
328
(i} For the sake of the environment
-Tire pressure that is too low
increases fuel consumption.
-Fuel consumption may also in­
crease when driving with the
comfort tire pressure is se­
lected .
(D Tips
Audi recommends using the
tire pressure specified for a
normal load
¢ table on
page 329
or for a full load
when the vehicle is partially loaded.
Make sure that the tire designa­
tion on your tire matches the des­ ignation on the tire pressure label
and the tire pressure table.
The following table lists recom­ mended tire pressures in cold
tires according to the load and
the size of the tires installed.
