186 Checking and filling
on the hot engine and exhaust system
when the engine is running -fire hazard!
- If your skin has come in contact with the
engine oil, you must subsequently
cleanse it thoroughly .
(D Note
- The oil level must not be above range 0
-danger of converter or engine damage!
Contact an authorized Audi dealer to
draw off oil, if necessary.
- Audi does not recommend the use of oil
additives. They may damage the engine
and adversely affect your New Vehicle
Warranty.
@ For the sake of the environment
- Under no circumstances can the oil come
in contact with the sewage network or
the soil.
- Observe and follow legal regulations
when disposing of empty oil containers.
Changing the engine oil
We recommend that have your oil changed by
an authori zed 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 compart
ment on page 180 .
The engine oil must be changed according to
the intervals specified in your Warranty &
Maintenance booklet. This is very important
because the lubricating properties of oil di
minish gradually during normal vehicle use .
Under some circumstances the engine oil
should be changed more frequently . Change
oil more often if you drive mostly short dis
tances , operate the vehicle in dusty areas or
under predominantly stop-and-go traffic con
ditions, or have your vehicle where tempera
tures remain below freezing for extended pe riods. Detergent
additives in the oil will make fresh
oil look dark after the engine has been run
ning for a short time. This is normal 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 ex
pertise required, we strongly recommend that
you have your oil changed by an authorized
Audi dealer or a qualified service station .
If you choose to change your oil yourself,
please note the following important informa
tion:
A WARNING
=
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot en-
gine oil, let the engine cool down to the
touch.
- When removing 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 run
ning down your arm.
- Drain the oil into a container designed
for this purpose, one large enough to
hold at least the total 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.
(D Note
Never mix oil additives with your engine
oil. These additives can damage your en
gine and adversely affect your Audi Limit
ed New Vehicle Warranty.
@ For the sake of the environment
- Before changing your oil, first make sure
you know where you can properly dispose of the used oil.
- Always dispose of used engine oil proper
l y. Do not dump it on garden soi l, wood
ed 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
The engine coolant performs two functions: it
keeps the engine from overheating and it pro
tects the engine from freezing in the winter.
The cooling system is sea led and generally re
qu ires little at tention.
The cooling system has been filled at the fac
tory with a permanent coolant which does not n eed to be changed. The coolant consists of a
mixture of wa ter and the man ufacturer's g ly
col-based coolan t addi tive Gl3 ant ifree ze
with ant icorrosion add itives (50% for USA
models; 60% for Canadian 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 the boiling po int of the
coolant.
Do not reduce the concentration of the coo l
ant in the summer by adding plain water.
The
proportion of coolant add itive must be at
lea st 50°/4 but not more than 60°/4
to ma in
tain antifreeze protection and cooling efficien cy. If the coolant frost pro tect io n is too low,
the coolant cou ld freeze and dam age the veh i
cle heating and eng ine cooling system.
For year-round driving, antifreeze is added at
the facto ry for temperatures down to:
- -31°F( -35°C)USA
- -40 °F ( -40 °C) Canada.
Checkin g and fillin g 187
A WARNING
Before you c heck anything in the engine
compartment, always read and heed all
W ARNI NGS~ &.
in Working in the engine
comportment on page 180.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your v ehicle is sufficient to meet the cli
mate conditions. This is especia lly impo r
t an t if you live in a region where t he win
t er is ex treme ly cold. If ne cessary, in
cr ease t he p ro portion of coo lant add itive
to 60%.
- Whe n adding cool ant additive to yo ur
c ooling sys tem, remember:
- We recommend us ing on ly coolant ad
d itive Gl2++ or Gl3 (check the labe l)
for your veh icle. This coolant additive is
ava ilable at autho rized Aud i dea le rs.
Othe r types of antifree ze can sig nifi
cantly reduce cor ros io n protec tion. The
res ulting co rrosion can cause a loss of
coolant an d serio us en gine damage.
- Do not add any type of rad iator le ak seal
ant to yo ur vehicle 's eng ine coolant .
Adding radiator repair flu id may adverse
ly affect the function and performance of
your cooling system and co uld resu lt in
damage not covered by you r New Ve hicle

Checking the engine coolant level
The engine coolant level con be checked with
a quick glance.

188 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 compart
ment on page 180.
• Park your vehicle on a level surface.
• Switch the ignition off.
• Read the coolant level at the coolant expan
s ion tank ¢
page 182, fig . 134. With a cold
engine, it must be above the "min" mark .
With a hot engine, it ca n be a little above
the indicated range .
The location of the coolant expans ion tank
can be seen in the engine compartment illus
tration
¢ page 182.
To obtain an accurate read ing, the engine
must be switched off.
The expansion tank in yo ur vehicle is equipped
with an e lectric coolant level sensor .
When the coo lant level is too low, the warning
light in the A uto- Check System ¢
page 16 will
illuminate until yo u add coo lant and the level
has been restored to normal. Even though
there is an electric coo lant level sensor, we
still recommend 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 author ized 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 overheat ing.
(D Note
Do not add any type of radiator lea k seal
ant to your 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 res ult 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 compart
ment on page 180 .
• Turn off the engine.
• Let the engine cool down.
• Place a thick rag over t he coo lant expansion
tank
¢ page 187, fig . 138 a nd carefully
tw ist the cap counter-clockwise ¢&_ .
• Add coo la nt.
• Twis t the cap on aga in
t ightly.
Replacement engine coolant must conform to
exact spec ificat ions ¢
page 18 7, Coolant.
Even in a n emerge ncy, if coolant add i-
t ive G1 2++, G12+ or G12 is not ava ilable , do
not use a d iffe ren 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 amount o f
coolant , then you sho uld add cold ant ifreeze
and co ld wate r on ly w hen the engine is cold.

,&. 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 yo ur face, hands and arms from
escaping fluid and steam by covering
the cap w ith a large, t hick rag.
- T urn the cap s lowly a nd ve ry carefully
in a counter-clo ckwise direction while
applying light, downward pres sure on
the top of the cap.
A WARNING
Sudden tire failure 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 risk of "hydroplaning " and loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from t ires.
- Tires age even if they are not be ing used
and can fail suddenly, especially at high
speeds . Tir es that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used tires on your vehicle if
you are not sure of their" previous histo
ry ." Old used tires may have been dam
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.

by Audi are spec ially matched to the charac
teristics of the vehicle and can make a major
contribution to good road holding and safe .,.
•
snow c hains are suitably cove red . Check
the position of the snow chains after
driving a few yards and correct if neces
sary. Follow the instructions from the
snow cha in manufacturer when doing so.
Where snow cha ins are mandatory oncer
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
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
ted, the correct wheel bo lts with the right
length and correctly shaped bolt heads must
be used. This ensures t hat wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -even if it
i s the same model
¢ page 245.
A WARNING
Imprope rly tig htened or maintained wh eel
bolts can become loose ca using loss of
con trol, a collision and serious person al in
jury.
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
wheel bolts can tu rn easily and be p rop
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose w hile d riving if greased or
o iled, even if tig htened to the specif ied
torque.
- Only use whee l bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintai n the co rrect tig htening
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss. If the tightening tor-
Tire s an d wheel s 213
que of t he whee l bolts is too low, they
can loosen and come out when the vehi
cle is mov ing. If the tig htening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torq ue whee l bolts diago
nally. After changing a whee l, the tor que
must be checked as soon as possible with a
torq ue w rench -prefe rably by an au thor
iz ed A udi de aler or qu alified workshop .
Low aspect ratio tires
Your Audi is factory -eq uipped w ith low aspect
r atio tires . These tires have been tho roughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handli ng under a var iety of driving condi
tions . Ask your authorized Audi dealer for
more d etails.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numeral represents the ratio
of the t ire's sidewa ll height in relation to its
t read width exp ressed in pe rce ntage. Conven
t iona l tires have a he ight/w idth rat io of 60 or
more.
The performanc e of low-a spect-ratio tire s is
particularly sensitive to impr oper inflation
pre ssure .
It is therefore important that low
a spect ratio tire s are inflated to the specified
pres sure and that the inflation pressure is
regularly checked and maintained. Tire pre s
sures should be checked at least once a month and always befo re a long trip
¢ page 202, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w it h potholes, curbs, gul lies ..,.
