Tread wear
The tr ead wear grade is a comp arati ve ra ting based o n the wear rat e
o f the tire when teste d un der co ntro ll ed conditions on a specifie d
governme nt test co urse.
For examp le, a tire graded
1 50 would wear one and one half (1 1/2)

due to var iat io ns in d riv in g ha bits, se rvice prac tices and differences in
road characterist ics and climate .
Traction
The trac tion gra des, from highes t to lowest, are AA, A, Band C. Those
grades represent the t ire's ab ility to s top o n wet pav ement as

& WARNING
The traction grade assigned to this tire is based on straight-ahead
braking traction tests, and does not include acceleration,
cornering, hydroplaning or peak traction characteristics.
& WARNING
The temperature grade for this tire is established for a tire that is
properly inflated and not overloaded . Excessive speed, underinfla­
tion , or excessive loading , either separately or in combination, can
cause heat buildup and possible tire failure. •
Winter tires
Winter tires can improve veh icle h andlin g on s now and
i c e. At t emper atures belo w 45 °F (7 °C) we re com mend
c h anging to winter tires.
In some heavy snow areas, loca l gover nments may require true
wi nte r or "s n ow" t ires, th ose wi th very dee ply cut t read . Th ese tire s
should only be used in pairs and be i nstalled on all four wheels . Mak e
s u re you purchase snow tires tha t are the same si ze and constr uction

After changing a wheel, the torque must be checked as soon as
possible with a torque wrench -preferably by an authorized Audi
dealer or qualified workshop. •
Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires. These tires
have been thoroughly tested and been selected specifically for your
model for their superb performance, road feel and handling under a
variety of driving conditions. Ask your authorized Audi dealer for
more details.
The low aspect ratio of these tires is indicated by a numeral of
55 or
less
in the tire's size designation. The numeral represents the ratio of
the tire's sidewall height in relation to its tread width expressed in
percentage. Conventional tires have a height/width ratio of 60 or
more.
The performance of low-aspect-ratio tires is particularly sensitive to
improper inflation pressure. It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pressure is regularly checked and maintained. Tire pres­
sures should be checked at least once a month and always before a
long trip=>
page 302, "Checking tire pressure" .
What you can do to avoid tire and rim damage
Low aspect ratio tires can be damaged more easily by impact with
potholes, curbs, gullies or ridges on the road, particularly if the tire is
underinflated.
In order to minimize the occurrence of impact damage to the tires of
your vehicle, we recommend that you observe the following precau­
tions:
• Always maintain recommended inflation pressures. Check your
tire pressure every 2,000 miles (3,000 km) and add air if necessary.
• Drive carefully 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 also cause damage to your tires. •
After any impact, immediately inspect your tires or have them
inspected by the nearest authorized Audi dealer. Replace a damaged
tire as soon as possible.
• Inspect your tires every 2,000 miles (3,000 km) for damage and
wear . Damage is not always easy to see. Damage can lead to loss of
air and underinflation, which could eventually cause tire failure. If
you believe that a tire may have been damaged, replace the tire as
soon as possible.
• These tires may wear more quickly than others.
• Please also remember that, while these tires deliver responsive
handling, they may ride less comfortably and make more noise than
other choices.
Reduced performance in winter/cold season
conditions
All tires are designed for certain purposes. The low aspect ratio, ultra
high performance tires originally installed on your vehicle are
intended for maximum dry and wet road performance and handling.
They are not suitable for cold, snowy or icy weather conditions. If you
drive under those circumstances, you should equip your vehicle with
all-season or winter tires, which offer better traction under those
conditions. We suggest you use the recommended snow or all-season
tires specified for your vehicle, or their equivalent.
Refer to=>
page 311 for more detailed information regarding winter
tires. •
Tire pressure monitoring system
Applies to veh icles: w ith tire pressure monitoring system
General notes '
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure recom­
mended by the vehicle manufacturer on the vehicle placard or tire
inflation pressure label. (If your vehicle has tires of a different size .,

Tires and wheels Ill _______________ _____.
than the size indicated on the vehicle placard or tire inflation pressure
label , you sho uld determine the proper tire infla tion pressure fo r
those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressu re monitoring sys tem (TPMS) that illuminates a low tire pres ­
sure telltale when one o r more of your t ires is s ignificantly under­
inflated. Accord ingly, when the low tire pressure tellta le illumi nates,
you should stop and check your tires as soon as possib le, and inflate
them to the proper p ress ure. D riving on a sign ificantly under-inflated
tire causes the tire to overheat and can lead to tire fa ilure . Under­
inflation also reduces f uel efficiency and tire tread life, and may
affect the vehicle's handling and stopping ability .
Please note that the TPMS is not a substitute for proper tire mainte­
nance, and it is the d river's responsibility to mainta in correct tire
pressure, even if under-inflation has not reached the level to trigger
ill umination of the TPMS low tire press ure te lltale.
Your vehicle has also been equipped w ith a TPMS malfunction indi­
cato r to indica te when the system is not operating properly . The
TP MS ma lf u nction indicator is combined with the low tire p ress ure
telltale. When the system detects a malfunct ion, the telltale will
fl ash for approximate ly one minute and then rema in continuously
illuminated. This sequence will continue upon subsequent vehicle
sta rt-ups as long as the malfunction exists.
When the ma lfunction indicator is illum inated, the system may not
be able to de tect or signa l low ti re pressure as intended . TPMS
ma lfunctions may occur fo r a var iety of reaso ns, includ ing the instal­
lation of replacement o r alternate tires or wheels on the vehi cle that
prevent the T PMS from functioning properly . Always check the TPMS
ma lfunction tellta le after replacing one or more tires or whee ls on
yo ur vehicle to ensure that the replacement o r alte rnate t ires and
wheels allow the TPMS to continue to funct ion proper ly .•

& WARNING
• If the tir e pres sure indicator appears in the instrument cluster
display, one or more of your tires i s significantly under-inflated.
Reduce your speed immediately and avoid any hard steering or
braking maneuvers. Stop as soon a s possible and check the tires
and their pressures . Inflate the tire pressure to the proper pres­
sure as indicated on the vehicle 's tire pressure label=>
page 300.
Driving on a significantly under -inflated tire causes the tire to
overheat and can lead to tire failure. Under -inflation also is likely
to impair the vehicle's handling and stopping ability.
& WARNING (co ntinued )
• The driver is re sponsible for maintaining the correct tire pres­
sures . You must check the tire pres sures regularly .
• Under certain conditions (such as a sporty driving style , winter
conditions or unpaved roads) , the pressure monitor indicator may
be delayed.
• Ask your authorized Audi dealer if run-flat tires may be used on
your vehicle . Your vehicle registration becomes invalid if you u se
the se tires when not permitted. Damage to your vehicle or acci­
dents could also result.

Replacing a fuse
A problem in the electrical system may be caused by a
blown fuse.
Fig. 244 Instrument
panel left: Face cover
- Locate the fuse which belongs to the component which
failed.
- Switch off the ignition and the electrical component affected.
- Carefully pry the face cover
off the instrument panel using
a screwdriver => fig. 244 .
- Remove the plastic clip from its retainer in the face cover,
place it over the questionable fuse and remove the fuse.
- Replace a blown fuse (recognizable by the melted metal
strip inside) with a fuse of the
same amperage.
The individual circuits are protected by fuses. The fuse panels with
the fuses are located on the left and right front faces of the instru-
Vehicle OP-eration
ment panel behind a cover and in the right storage area in the
luggage compartment.
There is a plastic clip in the cover on the left side of the instrument
panel, which can be used to remove the fuses. You will also find a
label on both covers in the instrument panel with the fuse layout for
the corresponding fuse panel.
& WARNING
Never replace a fuse with one that has a higher amperage rating.
• A fuse with a too high amperage could damage the electrical
part and cause a fire.
0 Note
• On no account should fuses be repaired (e.g. patched up with tin
foil or wire) as this may cause serious damage elsewhere in the elec­
trical circuit or cause fire .
• If a fuse blows repeatedly, do not keep replacing it. Instead, have
the cause of the repeated short circuit or overload located and fixed.
Ii] Tips
You are well advised to keep a supply of spare fuses in your vehicle .
Fuses with the proper ampere ratings are available at your authorized
Audi dealer. •

Bulbs
Replacing bulbs
F or your safety, we recommend that you have your autho­
ri zed Audi dealer replace any bulbs for you.
It is becoming increasingly more and more diff icult to rep lace vehicle
ligh t bulbs since in many cases, other parts o f the car must fi rst be
removed before yo u are able to get to the bulb . This applies especially
to the light bu lbs in the front of your car which you can on ly reach
throug h the engi ne compartment .
Sheet meta l and bu lb holders can have sharp edges that can ca use
ser ious cuts, parts must be co rrectly t aken ap art and the n properly
put back together to he lp prevent breakage of parts and long term
d am age fro m water t hat c an enter housings that have no t been p rop­
erly resea led.
For your safety, we recommend that you have you r authorized Audi
dealer replace any bulbs fo r you, since yo ur dealer has t he p roper
too ls, the correct bu lbs and the expertise.

& WARNING
• To reduce the risk of serious injury and vehicle damage.
-Always lift the vehicle only at the special workshop hoist and
floor jack lift points illustrated=>
page 338, fig. 254 and
=> page 338, fig. 255.
- Failure to lift the vehicle at these points could cause the
vehicle to tilt or fall from a lift if there is a change in vehicle
weight distribution and balance. This might happen, for
example, when heavy components such as the engine block or
transmission are removed .
• When removing heavy components like these, anchor vehicle
to hoist or add corresponding weights to maintain the center of
gravity. Otherwise , the vehicle might tilt or slip off the hoist ,
causing serious personal injury.
0 Note
• B e aw are of the following poi nts b efo re li fting the ve hicl e:
- The vehicle should never be lifted or jacked up from under­
neath the engine oil pan, the transmission housing , the front or
rear axle or the body side members . This could lead to serious
damage.
- To avoid damage to the underbody or chassis frame, a rubber
pad must be inserted between the floor jack and the lift points.
- Before driving over a workshop hoist, check that the vehicle
weight does not exceed the permissible lifting capacity of the hoist.
- Before driving over a workshop hoist, ensure that there is
sufficient clearance between the hoist and low parts of the
vehicle. •
