With all these variab les coming in to p lay, no
standard rate of oil consumption can b e es­
tablished or specif ied. There is no alternative
to regular and frequent checking of the oi l lev­
el, see
Note .
If the ye llow engin e oi l level warning symbol

Dr iving with an insuffic ient oi l level is like­
ly to ca use seve re damage to the eng ine .
{D) Tips
-The oil pressure warning display. is
not an indicator of the oil lev el. Do not
r ely on it . Instead, check the oil level in
your engine at regular intervals, pref ­
erably ea ch time you refuel , and always
befor e going on a long trip .
-If yo u have the impres sion you r engine
consumes excessive amo unts o f oi l, we
r ecommend that yo u consult your Audi
dealer to have the ca use of yo ur concern
properly diagnosed . Keep in mind that
the accurate measurement of oil con­
sumption requires great care and may
take some time . Your Audi dealer has in­
str uctions about how to measure oil con­
sumption accurate ly .

236 Tires and wheels
-Never mount used tires on yo ur 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.
Glossary of tire and loading terminology
Accessory weight
means the comb ined weight (in excess of
those standard items which may be rep laced)
of automatic transmission, power steering, power brakes, power windows, power seats,
radio, and heater, to the extent that these
items are availab le as factory -installed equip ­
ment (whether installed or not) .
Aspect ratio
means the ratio of the he ight to the w idth of
the tire in percent. Numbers of 55 or lower in­
dicate a low sidewall for improved steering re­
sponse and better overall handling on dry
pavement.
Bead
means the part of the tire that is made of
steel wires, wrapped o r reinforced by ply cords
and that is shaped to fit the r im.
Bead separation
means a breakdown of the bond between
components in the bead.
Cord
means the strands forming the plies in the
tire.
Cold tire inflation pressure
means the tire pressure recommended by the
vehicle manufacturer for a tire of a designated size that has not been driven for more than a
couple of miles (kilometers) at low speeds in
the three hour period before the tire pressure
is measured or adjusted. -
If you notice unusual vibration or if the
veh icle pulls to one side when driv ing, a l­
ways stop as soon as it is safe to do so and check the wheels and tires for dam­
age.
Curb weight
means the weight of a motor vehicle w ith
standard equipment including the maximum
capacity of fuel, oil, and coolant, air condi­
tioning and additional weight of optiona l
equipment.
Extra load tire
means a t ire design to operate at h igher loads
and at higher inflation pressures than the cor­
responding standard tire. Extra load tires may
be identified as "XL", "xl", "EXTRA LOAD", or
"R F" on the sidewall .
Gross Axle Weight Rating ( "GAWR ")
means the load-carrying capacity of a s ingle
axle system, measured at the tire-ground in­
terfaces .
Gross Vehicle Weight Rating ("GVWR")
means the maximum total loaded weight of
the vehicle.
Groove
means the space between two adjacent tread
ribs .
Load rating (code)
means the maximum load that a tire is rated
to carry for a given inflation pressure. Yo u
may not find this information on all tires be­
cause it is not required by law.
Maximum load rating
means the load rating for a tire at the maxi­
mum permissib le inflation pressure for that
tire.

The speed rating letter code (c::> page 23 7) is
on the side wall of the tire
c::> page 246.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed . Always know the maximum
speed before driving off. Never drive faster
than the speed permitted for your specific
winter tires . This will cause damage to the
tires leading to an accident and serious
personal injury to you and your passen­
gers.
A WARNING
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire failure in­ cluding a blowout and sudden deflation,
loss of control, crashes and serious per­
sonal injuries . Have worn or damaged tires
replaced immediately.
- Winter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed .
- Never drive faster than the speed for
which the winter or other tires installed
on your vehicle are rated .
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac­
celeration of the winter tires and all-wheel
drive tempt you into taking extra risks . Al­
ways remember :
- When braking, an all-wheel drive vehicle
handles in the same way as a front drive
vehicle.
- Drive carefully and reduce your speed on
icy and slippery roads, even winter tires
cannot help under black ice conditions.
@l For the sake of the environment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
-
Tires and wheels
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 0.4 inch
(10,S mm) , including the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
c::> (]) . For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
A WARNING ,..__
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different
sizes . Always make sure to follow the in­
structions provided by the snow chain manufacturer .
- When driving with snow chains never
drive faster than the speed permitted for
your specific snow chains .
- Always observe local regulations.
(D Note
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- 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
sary. Follow the instructions from the
snow chain manufacturer when doing so.
- If the Adaptive Air Suspension should
malfunction, do not mount or use snow ..,.

or ridges on the road, particularly if the tire is underinflated .
I n o rder to m inim ize the occu rrence of impact
damage to the t ires of your veh icle, we recom ­
mend that you observe the following precau­
tions :
- Always maintain recommended inflat ion
pressures. Chec k your tire pressure every
2,000 miles (3 ,000
km) and add air if neces­
sary.
- Drive carefu lly on roads with potholes, deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may a lso
cause damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Aud i dealer. Replace a damaged
t ire as soon as possible .
- Inspect your t ires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see. Damage can lead to loss of
air and underinflation, wh ich could eventu­
ally cause tire failure . If you be lieve that a
t ir e may have been damaged , replace the
t ire as soon as possible.
- T hese tires may wea r mo re qui ck ly than ot h­
ers.
- Please a lso remember that, whi le these tires
deliver respons ive handling, they may ride
l ess comfortably and make mo re noise than
othe r choices.
Reduced performance in winter /cold
season condition s
All tires are des igned for certa in pu rposes.
The low aspect ratio, ultra high performance
tires originally installed on your veh icle are in­
tended for maximum dry and wet road per­
formance and handling . They are not suitable
for cold , snowy or icy weather condit ions .
If
you dr ive under those circums tances, you
should equip your veh icle with all -season or
winter tires, which offer better traction under
those cond itions . We suggest you use the rec­
ommended snow or all-season tires specified
for your ve hicle, or their equ ivalent.

mation regard ing winter tires.
Tire pressure
monitoring system
ill General notes
Applies to veh icles: w ith t ire pressure monitoring system
Each tire, incl uding the spare (i f provided),
shou ld be checked monthly when co ld and in ­
flated to the inf lation pressure recommended
by the veh icle manufacturer on the veh icle
placard or tire inflation pressure label. (If your
vehicle ha s tires of a different size than the
s ize indicated on the vehicle placard or tire i n­
flat ion pressu re labe l, you shou ld dete rm ine
the p roper t ire inflation p ress ure fo r th ose
t ir es).
As an added safety feature , your ve hicle has
been equipped with a tire pressure mon ito ring
system ( TPMS) that illum inates a low ti re
pressure te lltale when one or more of your
tires is significant ly under -inflated . Acco rding­
l y, when the low tire pressure te lltale i llumi­
nates, you shou ld stop and check your tires as
soon as possib le, and inflate them to the
proper pressure. Driving on a sign ificantly un­
der- inflated t ire causes the tire to overheat
and can lead to tire fa ilure. Under -inflation al ­
so reduces fuel effic iency and tire tread life,
and may affect the vehicle 's hand ling and
stopp ing ability.
Please note that the TPMS is not a substitute
for proper tire ma intenance, and it is the driv­
er's respons ibility to maintain co rrect tire
pressure, even if under-inflation has not
rea ched the leve l to tr igger illum inat ion of the
T PMS low tire p ressure tellta le .
Your vehicle has also been equipped with a
T PMS ma lfunction indicator to ind icate when
the system is not operating prope rly . T he
T PMS ma lfunction indicator is combined w ith
the low tire pressure te lltale. When the sys­
tem detects a malfunction , the telltale wi ll
flash for approximate ly one min ute and then ..,_
