What impairs driving safety?
Safe driving i s directly rela ted to the condi­
t ion of the vehicle , the driver as well as the
driver 's abili ty to concentrate on the road
without being distracted .
The driver is responsib le fo r the s afety of the
ve hicl e an d all of i ts occupants . If you r ability
to d rive is impai red, safety r is k s for everybody
i n the vehicle increase and yo u also become a
hazard to everyone else on the road <=>
&_.
Therefore:
• Do no t let yo urself be dist racted by passen ­
gers or by using a cellular telephone.
• NEV ER drive when yo ur dr iv ing ability is im­
paired (by medicat ions, alcohol , drugs, etc.).
• Observe all traffic laws , rules of the road
and speed limits and plain common sense .
• ALWAYS adjust you r speed to road , traff ic
and weathe r con dit ions .
• Take frequent b reaks on long t rips. Do not
dr ive for more than two hours a t a str etch .
• Do NOT drive whe n you are t ired , under
pressure or when you are stressed .
A WARNING
Impaired driving safety increases the risk
of serious personal injury and death when­
ever a veh icle is being used.
Proper occupant
seating positions
Proper seating position for the driver
The proper driver seating position is impor­
t ant for safe, relaxed driving.
Fi g. 1 95 Correc t seat ing posit ion
For yo ur own safety and to reduce the risk of
injury in the event of an accident, we recom­
mend that you adjust t he driver's seat to the
fo llow ing pos ition:
• Ad just the driver's seat so that you can easi­
ly push the pedals all the way to the floor
while keepi ng your knee(s) slightly bent
¢ &_ .
• Adjust the a ngle of the seatback so that it is
in an upr ight position so that your back
comes in full conta ct w ith it when you d rive.
• Adjust t he steer ing whee l so that there is a
d is tance of at least 1 0 inches (2 5 cm) be ­
t ween the steer ing whee l and yo ur breast
bone ~
fig. 195. If not possible, see your a u­
thorized A udi dealer about adaptive equip ­
ment.
• Adjust the steer ing whee l so that t he steer­
ing wheel and airbag cover poi nts at your
ch est and not at your face .
• Grasp the top of the s teer ing wh ee l with
your elb ow(s) slightly ben t.
• Adjust t he head rest rain t so th e up per edge
is as even as possible wi th th e top of y our
head . If that is not poss ible, try to adjust
the head restraint so that it is as close to
this pos ition as possib le .

Trailer towing weights
With a factory-installed trailer hitch, the
maximum permissible trailer weight is 6,615
l bs (3,000 kg) . Th e maximum permissible un­
braked trailer weight is 1,650 lbs (750 kg).
With an
aftermarket trailer hitch, the maxi­
m um permissible trailer weight is 5,512 lbs
(2,500 kg) . These specifications apply when
driving on roads having an incline of less than
12%.
Permissible tongue load
F or best vehicle handling under these
changed condit ions, adjust the trailer load so
that the tongue load is at the maximum al­
lowable or slightly lower . You can get an ap ­
prox imation of the tongue load w ith a bath­
room scale or you can measure the load at a
trucking company or weighing station .
With a
factory-installed trailer hitch, the
maximum permissible load on the ball h itch may not exceed 662 lbs
(300 kg). With an
af­
termarket
trailer hitch, the maximum permis­
s ib le load on the ba ll hitch may not exceed
551 lbs (250 kg). It is recommended to use
the maximum permissible load.
Trailer load distribution
Be sure the load in the trailer is held secure ly
in place to prevent it from shifting forward,
backward or sideways.
Never allow a passenger to ride in a trailer
¢&. in Driving instructions on page 243.
Ball mount
The trailer hitch may only be used w ith suita­
ble ball mount and ball¢
fig. 233. In stalla­
tion of the hitch ball must be carried out in ac­
cordance with the manufac turer's instruc­
tions. At the height dimension of 1.5 in
(38.5 mm) a tolerance of +/- 0.5 in (12. 7 mm)
is permissib le.
Engine cooling system
Towing a trailer makes the engine work ha rd­
er . It is important that the cooling system's
performance is up to the additional load .
Make sure that the cooling system has enough
fluid .
Tire pressure
When towing a trailer, infla te the tires of your
vehicle to the cold tire pressu re listed under
" Full l oad" on the tire pressure label. The tire
pressure label is located on the driver's side B­
pillar . Inflate trailer tires to trailer and tire
manufacturers' spec ificat ions .

The headlight settings shou ld be checked with
the trai ler attached before driving
off. Check
to make sure both vehicle and trailer lights
are working properly.

24 6 Cl eaning and protec tio n
Automatic car wash
The vehicle can be washed in almost any
modern automatic car wash .
The vehicle paint is so durable that the vehicle
can normally be washed without problems in
an automatic car wash. However, the effect on
the paint depends to a large extent on the de­
sign of the facility, the filtering of the wash
water, the type of wash and care mater ial , etc.
I f the pa int has a dull appearance afte r going
through the car wash or is scratched, bring
this to the attention of the operator immedi­
ately. If necessary, use a different car wash.
Before going through a car wash, be sure to
take the usual precautions such as closing the
windows and the Panoramic sliding s unroof.
Factory installed antennas must not be re­
moved.
I f you have installed additional accessories on
the vehicle - such as spoilers, roof rack, etc. -
it is best to ask the car wash operator if these
should be removed.
A WARNING
Please take note of the following po ints
before going through an automatic car
wash with your vehicle, so that you can avoid damage to your vehicle .
- Compare the track of your vehicle with the distance between the gu ide rails of
the fac ility- there is a risk of damage to
the whee ls and t ires.
- Compare the height and w idth of your
vehicle with the height and width of the
tunnel at the facility.
- Fold the exte rior mirrors flat - there is a
risk of damag ing the exte rior m irrors.
Power folding exterior mirrors* mus t not
be folded in or out by hand. Use the pow­
er function!
- Do not al low the wiper blade to fall onto
the windshield after the vehicle is dried -
there is a risk of damag ing the paint on
the hood.
- Always read and heed all WARNINGS and other information ¢
page 245.
Washing the vehicle by hand
A lot of water is needed when washing a vehi­
cle by hand .
.,. Before you start washing, make sure you
have read and understood the WARNINGS
¢ .&. in General information on page 245 .
.,. First soak all dried d irt unt il it is soft, then
r inse it off .
.,. As you clean you r vehicle , start w it h the
roof and work your way down to the bottom,
using a sponge, a sponge g love or a clean
brush.
.,. Rinse the sponge or the sponge glove often,
flushing it clean each time.
.,. Use spec ial car shampoo only for very per­
sistent d irt .
.,. Rinse the car thoroughly wit h water .
.,. Use a chamo is leather to gently w ipe the ex-
ter ior d ry.
Use a separate sponge for cleaning the
wheels, door s ills and other regions exposed
to road dirt . In this way, you will not scratch
the pa int with coarse pa rticles imbedded in
the sponge the next time you wash the car.
A WARNING ~ -
- Do not clean the underside of the chas­
sis, fenders, wheel covers , or other ha rd
to reach pa rts without protect ing your
hands and arms . You may cut yourself on
sharp-edged metal parts.
- Always read and heed a ll WARNINGS and
other information ¢
page 245.
(D Note
- Never try to remove dirt, mud or dust if
the surface of the ve hicle is dry . Never
use a dry cloth or sponge, s ince this
co uld scratch your vehicle's paint or win ­
dows .
- Never wash your car in bright s unlight.
Drops of water act as magn ifying lenses
and may damage your paint .
- When you wash your car in the winter: if you rinse your vehicle with a hose, be careful not to aim the stream of water

-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have bee n dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.

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. Tires and wheels 291

,&.
We recommend that all work on tires and
wheels be perfo rmed by an authorized Audi
dealer. They are familiar with recommended
proced ures and have the necessary spec ial
too ls and spare parts as well as the proper fa­
cilities for disposing of the old tires.
Authorized Audi dealers have the necessary information about technica l requ irements for
installing or changing tires and r ims.
Replacing tires and wheels
Tires should be rep laced at least in pairs and
not individually (for example both front tires
or both rear tires together).
Be sure to read and heed the information to
the tire pressure monitoring system
¢pa ge 298.
Always buy rep lacement radial tires that have
the same specifications as the tires approved
for your vehicle by Audi. Replacement t ires
must always have the same load rating speci­
fication as the original equipment or approved
optional tires listed in the table
c:> page 284.
Aud i-approved specification tires are specially
matched to your vehicle and its load limits,
and can contribute to the important road hold­
ing, driving characteristics, and safety of the
vehicle. The table
(<:>page 284) lists specifica­
ti ons of the tires approved for the Audi mod­
els covered by your Owner's Literature .
The tire pressure labe l located on the driver's
side B-pillar
c:> page 284, fig. 252 lists the
specif ications of the original equipment tires
installed on your vehicle at the time it was
manufactured.
Federal law requires tir e manufacturers to
place standard ized information on the s ide­
wall of all tires
c:> fig. 255. This information
id ent ifies and describes the fundamental
characterist ics, the quality grade of the tire
and also provides a tire ident ificat ion number f
or sa fety standard ce rtification and in case of

Tire specifications
Knowledge of tire specificat ions makes it eas­
ier to choose the correct tires. Radial tires
have the tire specifications marked on the
sidewa ll, for examp le:
P255 / 55 R 18 109 H XL
This co nta ins the following information:
P Indicates the tir e is for passenger cars
(where app licab le)
255 Nominal tire width in mm of the tire

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
t e d, the cor rect wheel bolts wit h the right
lengt h and correctly s haped bolt heads must
be used. This ens ures t hat w heels a re fitted

correctly.
I n ce rtain circumstances, you may not use
wheel bo lts from a d ifferent vehicle -even if it
is the s ame mode l
~page 32 7.
& WARNING
Improperly tig htened or maintained whee l
bolts can become loose ca using loss of
cont ro l, a co llision and serious persona l in­
jury.
- Always keep the w heel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­ erly t ightened.
- Never grease or oil the wheel bolts and the threads in the wheel hubs. They can
become loose w hile driving if greased or
o iled, even if tig hte ned to the specified
torq ue.
Tire s an d wheel s 297
-On ly use whee l bolts that be long to the
rim being installed.
- Never use different wheels bolts on yo ur
veh icle.
- Always maintain the correct t ightening
torque for the whee l bolts to reduce t he
risk o f a wheel loss. If the tightening tor­
que of t he wheel bolts is too low, they
can loosen and come out when t he vehi­
cle is mov ing.
If the tig hte ning torque 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
