Wheel bolts
W heel b olts mus t al wa ys be tigh te n ed to t he cor rect
to rqu e.
The design of wheel bolts is matched to the factory instal led rims . If
d ifferen t rims are fitted, the co rrect w heel bo lts wit h th e rig ht length
and correctly shaped bolt heads m ust be used. This ensures that
w hee ls are fitt ed s ecure ly a nd th at t he brake sys te m funct ions
correctly .
I n certain circums tances, yo u may no t use w heel b olts fr om a
differ ent vehicle -even if it is the same model::::;,
page 296.
&_ WARNING
Improperly tightened or maintained wheel bolts can become loose
causing loss of control , a collision and serious personal injury.
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolts can turn easily and be properly tightened.
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while driving if greased or oiled,
even if tightened to the specified torque .
• Only use wheel bolts that belong to the rim being installed.
• Never use different wheels bolts on your vehicle.
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss. If the tightening torque of
the wheel bolts is too low , they can loosen and come out when the
vehicle is moving . If the tightening torque is too high, the wheel
bolts and th reads can be damaged and the wheel can become
loose .
0 Note
The specified torque for the wheel bolts is 90 ft lb (120 Nm) with a
t ole ranc e of ± 7,4 ft lb(± 1 0 Nm). To rque whee l bolts diag onally.
After changing a wheel, the torque must be checked as soon as possible with a to
rque wrench -preferab ly by an authorized Audi
dea ler o r qu alif ied wo rksh op.•
Low aspect ratio tires
Yo ur Audi is fac tory-equip ped wi th l ow asp ect rati o tires. Th ese tires
have been thorough ly tested and been selected specifically for your
mod el for thei r su per b p erfo rma nce, road feel an d handl in g u nder
a variety of driving conditions . Ask your author ized Aud i dea ler for
mo re deta ils.
T he low aspec t ra tio o f th ese t ires is ind icate d by a numera l o f 55 or
less in the t ire's size designation. The numera l represents the ratio
of the ti re's s idewa ll height in re la ti on to its tread w idth e xpress ed
in percentage. Conventiona l tires have a height/width ratio of 60 or
mo re .
The performan ce of low -aspect -ratio t ires is part icularly 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 alway s before a
long trip::::;,
page 244, "Checking tire p ressure".
What you can do to a void tire and rim damage
L ow a spect ratio tires can be damaged more easi ly by impact with
potho les, curbs, gull ies or ridges on the road, particularly if the t ire
is underinflated.
In orde r to minimi ze the occurrence o f im pact da mage to th e tire s
of your vehicle, we recommend that you observe the fo llowing
p reca utions:
• Always ma intain reco mm ende d inflat io n pressu res . C heck your
tire p ressure every 2, 000 miles (3 ,000 km) and add ai r if neces sary .
• D rive car eful ly on roads with potholes, deep gullies or ridges.
Th e impact from d riving th ro ugh o r ove r such o bstac les can
dama ge you r tires . Impact w ith a curb may also cause da mage to
your tires . .,_

The various electrical circuits are protected by fuses . The fuses are
clustered in a central ized unit. The unit is located behind the face
panel at the end of the instrument panel.
Two spare fuses and a sticker identifying the fuses are located on
the inside of the fuse box cover.
You are wel l advised to keep a supply of spare fuses in your vehicle .
Fuses with the proper ampere ratings are availab le at your autho­
rized Audi dealer .
& 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 for the repeated short circuit or overload tracked and
fixed. •

Bulbs
Replacing light bulbs
For your safety, we recommend that you have your autho­
rized Audi dealer replace burned out bulbs for you.
It is becoming increasingly more and more difficult to replace
vehicle light bulbs since in many cases, other parts of the car must
first be removed before you are able to get to the bulb. This applies
especially to the light bulbs in the front of your car which you can
only reach through the engin e compartment .
Sheet metal and bulb holders can have sharp edges that can cause
serious cuts, and parts must be correctly taken apart and then prop­
erly put back together to help prevent breakage of parts and long
term damage from wa ter that can enter housings that have not
been properly resealed.
For your safety , we recommend that you have your authorized Audi
dealer replace any bulbs for you, since your dealer has the proper
tools, the correct bulbs and the expertise.
Gas discharge lamps (Xenon lights)*:
•
Due to the high electrical voltage, have the bulbs replaced by a qual­
ified technician. Headlights with Xenon light can be identified by the
high voltage sticker.
& WARNING
Contact with high-voltage components of the electrical system
and improper replacement of gas discharge (Xenon) headlight
bulbs can cause serious personal injury and death.
• Xenon bulbs are pressurized and can explode when being
changed.
• Changing Xenon lamps requires the special training, instruc­
tions and equipment .
• Only an authorized Audi dealer or other qualified workshop
should change the bulbs in gas discharge lamps.
& WARNING
There are parts with sharp edges on the openings and on the bulb holders that can cause serious cuts.
• If you are uncertain about what to do, have the work performed
by an authorized Audi dealer or other qualified workshop. Serious
personal injury may result from improperly performed work.
[ i] Tips
• If you must replace the light bulbs yourself, always remember
that the engine compar tment of any vehicle is a hazardous area to
work in. Always read and heed all WARNINGS =>
page 212, "Engine
compartment"=> &.
• It is best to ask your authorized Audi dealer whenever you need
to change a bulb. •

& 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 283, fig. 188 and
~ page 283, fig. 189.
- 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
• Be aware of the following points before lifting the vehicle:
- 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. •

Weights
Gross Vehicle Weight Rating
The Gross Vehicle Weight Rating (GVWR), and the Gross Axle Weight
Rating (GAWR) for front and rear are listed on a sticker on the left
door jamb.
Controls and equip­ ment Safety first Vehicle operation
The
Gross Vehicle Weight Rating includes the weight of the basic
vehicle plus full fuel tank, oil and coolant, plus maximum load,
which includes passenger weight (150 lbs/68 kg per designated
seating position) and luggage weight.
Gross Axle Weight Rating
The Gross Axle Weight Rating is the maximum load that can be
applied at each axle of the vehicle~&.
Vehicle capacity weight
The vehicle capacity weight (max. load) is listed either on the
driver's side 8 -pillar or inside the fuel filler flap.
& WARNING
• The actual Gross Axle Weight Rating at the front and rear axles
should not exceed the permissible weights, and their combination
must not exceed the Gross Vehicle Weight Rating.
• Exceeding permissible weight ratings can result in vehicle
damage, accidents and personal injury.
0 Note
• The vehicle capacity weight figures apply when the load is
distributed evenly in the vehicle (passengers and luggage). When
transporting a heavy load in the luggage compartment, carry the
load as near to the rear axle as possible so that the vehicle's
handling is not impaired.
• Do not exceed the maximum permissible axle loads or the
maximum gross vehicle weight. Always remember that the vehicle's
handling will be affected by the extra load. Therefore, adjust your
speed accordingly.
• Always observe local regulations. •

standards. Therefore, vehicles built for the U.S .A. and Canada differ
from vehicles sold in other countries.
If you plan to take your vehicle outside the continental limits of the
United States or Canada, there is the possibility that
• unleaded fuels for vehicles with catalytic converter may not be
available;
• fuel may have a considerably lower octane rating. Improper fuel
may cause engine damage;
• service may be inadequate due to lack of proper service facilities,
tools or testing equipment;
• replacement parts may not be readily available .
• Navigation systems for vehicles built for the U.S.A. and Canada
will not necessarily work in Europe , and may not work in other coun­
tries outside of North America.

Maintenance
General
Your vehicle has been designed to help keep maintenance require­
ments to a minimum. However, a certain amount of regular mainte­
nance is still necessary to assure your vehicle 's safety, economy and
reliability. For detailed vehicle maintenance consult your Mainte­
nance & Warranty booklet .
Under difficult operating conditions, for example at extremely low
outside temperatures, in very dusty regions, etc., some service work
should be performed between the intervals specified . This applies
particularly to:
• oil changes , and
• cleaning or replacing the air filter.
~ For the sake of the environment
By regularly maintaining your vehicle, you help make sure that emis ­
sion standards are maintained, thus minimizing adverse effects on
the environment. •
Important considerations for you and your
vehicle
The increasing use of electronics, sophisticated fuel injection and
emission control systems, and the generally increasing technical
complexity of today's automobiles, have steadily reduced the scope
of maintenance and repairs which can be carried out by vehicle
owners. Also, safety and environmental concerns place very strict
limits on the nature of repairs and adjustments to engine and trans­
mission parts which an owner can perform.
Maintenance, adjustments and repairs usually require special tools,
testing devices and other equipment available to specially trained .,_
