Changing the engine oil
We recommend that have your oil changed by
an authorized Audi dealer or a qualified serv­
ice station .
Before you check anything in the engine com­
partment,
always read and heed all WARN·
INGS
¢ .&. in Working in the engine comport·
menton page 178 .
The engine oil must be changed according to
the intervals specified in your Warranty
&
Maintenance book let . T his is very important
because the l ubricating prope rties of oil di­
minish gradua lly dur ing no rmal veh icle use .
Under some circumstances the engine o il
should be changed more frequently . Change
oil more often if you drive most ly short dis­
tances , ope rate the vehicle in dusty areas or
u nder predominantly stop -and-go t raffi c con­
d itions, or have your veh icle w here tempe ra ­
tures rema in below free zin g fo r ex tended pe­
riods .
D ete rge nt add it ives in the o il w ill ma ke fresh
oil look dark after the eng ine has been run­
n ing fo r a shor t time. This is no rm al and is not a
reason to change t he oil more often than
recommended.
B ecau se of the p rob lem of p roper dispos al,
along wi th the specia l tools and necessa ry ex ­
pert ise req uired, we st rongly recommend tha t
yo u have your oil changed by an a uthorized
Audi dealer or a qualified service station.
If you choo se to change your oil your self ,
please note the fo llowing important info rma ­
tion:
A WARNING
-To reduce the risk of pe rsonal in jury if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot en-
g ine oil, let the engine cool down to the
touch.
- When removing the o il dra in p lug with
your fingers, stay as far away as possib le.
Always keep your forearm parallel to the
ground to help prevent hot oil from run·
n ing down your arm.
- Dra in the oil into a container designed
for this purpose, one la rge enough to
hold a t least the tota l amount of oi l in
your e ng in e.
- Engine oil is poisonous . Keep it we ll out
of the reach of childre n.
- Continu ous contact wit h used eng ine o il
is harmful to yo ur s kin. Always protec t
your skin by washing oil off tho ro ughly
wit h soap an d wate r.
(D Note
Never mix oil additives with your engine
o il. These additives can damage your e n·
gin e and adversely affect your Audi Limit­
ed New Veh icle Warranty.
@ For the sake of the environment
-Befo re changi ng your oil, first make s ure
you know where you can prope rly dispose
of t he used oil.
- Always dispose of used eng ine oi l proper -
ly. Do not dump it on garden soil,
IJJ,-

wooded areas, into open streams or
down sewage drains.
- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service station.
Engine cooling system
Coolant
T he engine coolan t performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
quires little attention .
T he cooling system has been filled at the fac­
tory with a permanent coolant which does not
need to be changed . The coolan t consis ts of a
mixture of water and the manufacturer 's gly ­
col-basedcoolant additive G12 ++ antifreeze
with anticorrosion additives (50% for USA
models; 60% for Canad ian models). This mix­
ture both assures the necessary frost protec­
tion and protects metal components in the
engine 's cooling system from corrosion and
scaling. It also raises th e boiling point of the
c oolant.
Do not reduce the concentration of the coo l­
ant in the summer by adding plain water .
The
proportion of coolant additive must be at
least 50% but not more than 60%
to main­
tain antifree ze protection and cooling efficien­
cy . If the coolant frost protection is too low,
the coolant could freeze and damage the veh i­
cle heating and eng ine cooling system .
For year-round driving, an tifree ze is added at
the factory for temperatures down to:
- -31 ° F ( - 3 5 °C) USA
- -40 °F ( -40 °C) Canada.
You can mix the G12 ++ coolant addit ive with
other additives (G12+ or G12) . Always check
with your authorized Audi dealer.
& WARNING
Before you check anything in the engine
compartment, always read and heed all
-
Checkin g and fillin g 185
WARNINGS c:::> .& in Working in the engine
compartment on page 178.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
mate conditions. This is especially impor­
tant if you live in a region where the win­
ter is extreme ly cold . If necessary, in­
crease the proportion of coo lant add itive
to 60% .
- Whe n adding coolant additive to your
cooling system, remember :
- We recommend using only coo lant ad­
ditive G12++ (check the labe l) for your
vehicle . This coolant additive is avai la­
ble at authorized Audi dealers. Other
types of ant ifreeze can significantly re­
duce corrosion protection . The result­
ing corrosion can cause a loss of cool ­
ant and ser ious eng ine damage.
- Do not add any type of rad iator leak seal ­
ant to yo ur vehicle's engine coolant .
Add ing radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could resu lt in
damage not covered by your New Vehicle
Limited Warranty .
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance.

186 Checking and filling
Before you check anything in the engine com­
partment,
alwa ys r ea d and heed all WARN­
INGS ¢ A in Working in the engine
comportment on page 178.
• Switch the ignition off .
• Read the coo lant level at the coolant expan­
s ion tank ¢
fig. 141 . With a co ld engine, it
must be above the "min" mark. W ith a hot
engine, it can be a little above the indicated
range.
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration .
To obtain an accurate reading , the engine
must be switched
off.
The expansion tank in you r vehicle is equipped
with an e lectric coolant level sensor .
When the coolant level is too low, the warning light in the Auto- Check System ¢
page 31 will
blink until you add coo lant and the level has
been restored to no rma l. Even though there is
an electric coolant level sen sor, we still rec­
ommend you check the coolant leve l from
time to time.
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 A udi 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.
@ Note
Do not add any type of ra diator leak seal­
ant to yo ur vehicle's eng ine coolant. Add ­
ing radiator repair f luid 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 anyth ing in the engine com­
partment,
always read and heed all WARN­
INGS ¢ A in Working in the engine comport­
ment on page 178 .
•Turnoff the engine.
• Let the eng ine cool down.
• Place a thick rag ove r the coolant expansion
tank
¢ page 185, fig . 141 and carefully
tw ist the cap counter-clockwise ¢&_ .
• Add coolant.
• Twis t the cap o n aga in
tightly.
Replacement engine coolant must conform to
exact spec ificat ions
¢ page 185, Coolant.
E ven in a n emerge ncy, if coo lant addi -
t ive G1 2++, G12+ or G12 is not ava ilable , do
not use a d ifferen t addit ive. Use plain water
instead unti l you can get the cor rect additive
and can restore the correct ratio . This sho uld
be done as soon as possible .
If you have los t a considerab le amo unt o f
coolant , then you sho uld add cold ant ifreeze
and co ld wate r on ly w hen the engine is cold.
Always use
new engine coo la nt whe n refilling .
Do not fill coola nt above the "MAX" mark. Ex­
cess coo la nt wi ll be fo rced o ut through the
pressure relief valve in t he cap w hen the en­
gine becomes hot.
,&. WARNING ~ -
- T he cooling system is under pressure and
can get very hot. Reduce the risk of
scalding from hot coolant by followi ng
these steps.
- T urn
off the engine and allow it to coo l
down.
- Protect you r face, hands and a rms from
esca ping fluid and steam by covering
the cap w ith a large, t hick rag.
- T urn the cap slowly a nd ve ry carefully
in a counter-clo ckwise direction while
applying light, downward pres sure on
the top o f the cap.

202 Tires and wheels
@ For the sake of the environment
Underinflated tires will a lso increase the
fue l consumption.
Tires and vehicle load limits
There are limits to the amount of load or
weight that any vehicle and any t ire can carry.
A vehicle that is overloaded w ill not handle
well and is more difficult to stop. Overload ing
can not only lead to loss of vehicle control,
but can also damage important pa rts of the
vehicle and can lead to s udden tire failure, in­
cluding a blowout and sudden deflation that
can cause the vehicle to crash.
Your safety and that of your passengers a lso
depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the vehicle. These
l oad limits are technically referred to as the
vehicle's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of fuel, oil, coo lant and other fluids plus
maximum load. The maximum load includes
the number of passengers that the vehicle is
intended to carry ("seating capacity") with an
assumed weight of 150 lbs (68 kg) for each
passenger at a designated seat ing pos ition
and the total weight of any l uggage in the ve­
h icle.
The
Gross Axle Weight Rating ("GAWR") is
the maximum load that can be app lied at each
of the vehicle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance stick er labe l located on the
driver 's side 8-p illar. Your Audi has 2 seat ing
positions. Each seating pos ition has a safety
be lt ¢
page 107, Safety belts.
The fact that the re is an upper limit to your
vehicle's Gross Vehicle Weight Rating means
that the tota l weight of whatever is being car­
ried in the vehicle is limited. The more passen­
gers in the vehicle or passengers who are heavier
than the standard weights assumed
mean that less weight can be carried as lug­
gage.
T he tire pressure label on your Audi also lists
the maximum combined weight of a ll of the
occupants and luggage or other cargo that
the vehicle can carry. For the location of the
label ¢
page 198, fig. 146.
A WARNING
Overloading a vehicle can cause loss of ve­
h icle control, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more we ight than your veh icle
was des igned to carry will prevent the
veh icle from handling properly and in­
crease the risk of the loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle w ithin a safe distance .
- Tires on a vehicle that has been overload­
ed can fail suddenly, including a blowout
and 5udden deflation, cau5ing lo55 of
control and a crash.
Determining correct load limit
Use the example below to cal­
culate the total weight of the passengers and luggage or oth­
er things that you plan to trans­
port so that you can make sure
that your vehicle will not be
overloaded.
Steps for Determining
Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF QC­
CU PANTS AND CARGO
SHOULD NEVER EXCEED XXX .,..

204 Tires and wheels
c::>fig . 148 running across the tread. Depend­
ing on the make, there will be six to eight of
them evenly placed around the tire. Marks on
the tire sidewall (for example "TWI" or other
symbols) indicate the positions of the tread
wear ind icators . Worn tires must be replaced .
Different figures may apply in other countries
c::> ,& .
Tire pressure
Incorrect tire pressure causes premature wear
and can cause sudden tire blow-out . For this
reason, tire pressure must be checked at least
once a month
c::> page 200.
Driving style
Driving fast around curves, heavy acceleration
and hard braking increase tire wear.
Rotating tires for more even wear
For a ll four tires on your vehicle to have the
same service life, we recommend that the
front and rear tires are rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­
ing:
- Tire rotation interva ls may differ from the
vehicle serv ice intervals outlined in your
Warranty
& Maintenance Booklet.
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points; therefore, we recommend that you
follow the tire manufacture r's suggested
t ir e rotation intervals .
- Vehicles with front-wheel drive experience
more tread wear on the front wheels com ­
pared to all-wheel drive (quatt ro ® ).
- Please rotate t ires as shown
c::> fig . 149.
-Extra care must be taken when rotating di-
rect ion-specific tires
c::> page 226.
Wheel balancing
The whee ls on new vehicles are balanced.
However, various situations during everyday
driving can cause them to become unbal­
anced, resulting in vibrations you can usually
feel through the steering wheel. Unbalanced
wheels must be rebalanced to
avoid excessive wear on steering, suspension
and t ires . A whee l must also be reba lanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect wheel alignment can cause exces­
sive tire wear, impairing the safety of the vehi ­
cle. If tires show excessive wear, have the
whee l alignment checked by an authorized
Audi dealer or qualified workshop.
All Wheel Drive
Vehicles with quattro ® must a lways have tires
of the same size, construction and tread type .
For details see c::>page
154.
A WARNING
-Sudden tire fai lure can lead to loss of con-
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard, they do not grip well on wet roads and increase
your r isk of "hydroplaning" and loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from tires.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith special care and at lower
speeds.
- Never mount used tires on your vehicle if
you are not sure of their "previous histo­
ry." O ld used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire fai lure
and loss of vehicle control.

210 Tir es and whe els
Snow chains
Snow chains may be fitted only to the front
wheels, and only to certain tire sizes. Ask your
authorized Audi dealer on which tire sizes
snow chains can be used.
If you are going to use snow chains , then you
must install them on the front wheels at
least.
The snow chains must have low-profile links
and must not be thicker than 0.53 inch
(13.S mm), including the lock .
Remove wheel center covers and tr im discs
before putting snow cha ins on your vehicle
¢ Q) . For safety reasons cover caps must the n
be fitted over the whee l bolts. These are avai l­
ab le from authorized Audi dea lers.
A WARNING
Using the wrong snow chains for yo ur vehi ­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
ser ious personal inj ury.
- Snow chains are ava ilable in different
sizes. Always make sure to follow the in­
struct ions provided by the snow chain
manufacturer .
- When driving w ith snow chains never
dr ive faster than the speed permitted for
your specific snow cha ins.
- Always observe local regulat ions.
([) Note
-Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wear ing the snow
chains down unnecessar ily.
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered. Check
the position of the snow chains after
driving a few yards and correct if neces­
sa ry. Follow the i nstructions from the
snow cha in manufacture r when doing so.
(D Tips
Where snow chains are mandatory on cer­
tain roads, th is normally a lso applies to ve­
hicles with All Whee l Dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
T he design of wheel bo lts is matched to the
factory installed rims. If different rims are fit­
ted, the correct whee l bolts with the right
l ength and correctly shaped bolt heads must
be used. Th is ensures that wheels are fitted
securely and that the brake system functions correctly.
In certa in circumstances, you may not use
whee l bolts from a different vehicle -even if it
is the same model
¢page 243.
A WARNING
-Imp roperly t ightened or ma inta ined wheel
bo lts can become loose causing loss of
control, a coll is ion and serious pe rsonal in­
jury.
- Always keep t he wheel bo lts and the
threads in the wheel hubs clean so the
wheel bo lts can turn easily and be prop­
erly tightened.
- Never grease or oil the wheel bolts and
the threads in the whee l hubs . They can
become loose while driving if g reased or
oiled, even if tightened to the specified
torque.
- Onl y use whee l bolts that belong to the
rim being installed.
- Never use different wheels bo lts on yo ur
vehicle .
- Always maintain the correct tightening
torque for the whee l bolts to reduce the
risk of a whee l loss. If the tightening tor­
que of the whee l bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tightening torque is
too high, the wheel bolts a nd threads
