What impairs driving safety?
Safe driving is directly related to the condi­
tion of the vehicle, the driver as well as the
driver's ability to concentrate on the rood
without being distracted.
The driver is responsible for the safety of the
vehicle and all of its occupants. If your ability
to drive is impaired, safety risks for everybody
in the vehicle increase and you also become a
hazard to everyone else on the road ¢
.&,.
Therefore:
• Do not let yourself be distracted by passen­
gers or by using a cellular telephone.
• NEVER drive when your dr iving 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 your speed to road, traffic
and weather conditions.
• Take frequent breaks on long trips . Do not
drive for more than two hours at a stretch .
• Do NOT drive when you are tired , under
pressure or when you are stressed.
A WARNING ,.
Impai red driving safety increases the risk
of serious personal injury and death when­
ever a vehicle is being used.
Proper occupant
seating positions
Proper seating position for the driver
The proper driver seating position is impor­
tant for safe, relaxed driving.
Fig. 99 The correct distance between driver and steer­
ing whee l
For your own safety and to reduce the risk of
injury in the event of an accident, we recom­
mend that you adjust the driver's seat to the
f o llow ing position:
• Adjust the driver's seat so that you can easi­
ly push the pedals all the way to the floo r
while keeping your knee(s) slightly bent
q &_.
• Adjust the angle of the seatback so that it is
in an upright position so that your back
comes in full contact with it when you drive.
• Adjust the steering wheel so that there is a
distance of at least 10 inches (25 cm) be­
tween the steering wheel and your breast bone¢
fig. 99 . If not possible, see your au­
thorized Audi dealersh ip about adaptive
equ ipment.
• Adjust the steering wheel so that the steer­
ing wheel and airbag cover points at your
chest and not at your face.
• Grasp the top of the steering whee l with
your elbow(s) slightly bent.
• Adjust the he ad restraint so the upper edge
is as even as possible with the top of your
head . If that is not possible, try to adjust
the head restraint so that it is as close to
this pos ition as possib le.
• Fasten and wear safety belts correctly

~ Distribute the load evenly in the luggage
compartment.
~ Always place and properly secure heavy items in the luggage compartment as far
forward as possible.
& WARNING
Improperly stored luggage or other items
can fly through the vehicle causing serious
personal injury in the event of hard brak­
ing or an accident. To help reduce the risk
of serious personal injury :
- Always put objects, for example, luggage
or other heavy items in the luggage com­
partment.
- Always secure objects in the luggage
compartment using the tie-down eyelets
and suitable straps.
& WARNING , ~
Heavy loads will influence the way your ve­
hicle handles. To help reduce the risk of a
loss of control leading to serious personal
injury:
- Always keep in mind when transporting
heavy objects, that a change in the cen­
ter of gravity can also cause changes in
vehicle handling:
- Always distribute the load as evenly as
possible.
- Place heavy objects as far forward in
the luggage compartment as possible.
- Never exceed the Gross Axle Weight Rat­
ing or the Gross Vehicle Weight Rating
specified on the safety compliance stick­
er on the left door jamb. Exceeding per­
missible weight standards can cause the
vehicle to slide and handle differently.
- Please observe information on safe driv­
ing
~ page 91.
& WARNING
To help prevent poisonous exhaust gas
from being drawn into the vehicle, always
keep the rear lid closed while driving.
- Never transport objects larger than

area because the rear lid cannot be fully
closed.
- If you absolutely must drive with the rear
lid open, observe the following notes to
reduce the risk of poisoning:
- Close all windows,
- Close the convertible top,
- Open all air outlets in the instrument
panel,
- Switch off the air recirculation,
- Set the fresh air fan to the highest
speed.
& WARNING ~
Always make sure that the doors, all win-
dows, the convertible top and the rear lid
are securely closed and locked to reduce
the risk of injury when the vehicle is not
being used.
- After closing the rear lid, always make
sure that it is properly closed and locked .
- Never leave your vehicle unattended es ­
pecially with the rear lid left open . A
child could crawl into the vehicle through
the luggage compartment and close the
rear lid becoming trapped and unable to
get out. Being trapped in a vehicle can
lead to serious personal injury.
- Never let children play in or around the
vehicle.
- Never let passengers ride in the luggage
compartment. Vehicle occupants must
always be properly restrained in one of
the vehicle's seating positions.
(D Tips
- Air circulation helps to reduce window
fogging. Stale air escapes to the outside
through vents in the trim panel, on the
left side of the luggage compartment. Be sure to keep these slots free and
open.
- The tire pressure must correspond to the
load. The tire pressure is shown on the
tire pressure label. The tire pressure la­
bel is located on the driver's side B-pillar .

Braking
General information
What affects braking efficiency?
Operating conditions and d riving habit s
The brakes on today's automob iles are st ill
subject to wea r, depend ing largely on operat­
i ng cond itions and dr iv ing habits
c:> & . On
ve hicles that a re e ithe r dr iven mostly in stop­
and-go city traffic o r a re driven ha rd , the
b rake pads should be checked by yo ur auth or­
iz ed A udi dealer more often th an specifie d in
the
Warranty & Maintenance booklet . Fail ure
to have your b ra ke pads inspected can res ult
in red uced b rake performance.
O n steep slopes, yo u sh ou ld use t he b ra ki ng
effect of the engine . This way, yo u preven t un­
necessa ry wear on the brake system . If you
must use yo ur brakes, do not ho ld the bra kes
down continuously . P u mp the brakes at inter­
va ls.
N oises may occur w hen braking depending on
the speed, bra king force and outside condi ­
tions s uch as temperature and h umidity.
Moisture or road salt
Unde r cert a in co ndi tions, for examp le, w hen
d riving through wate r or ve ry heavy rain , or
even after washing yo ur vehicle , the braking effect can be
reduced due to mois ture (or in
freez ing cond itions ice) on the brake pads. A
f ew cautio us brake applications s hou ld dry off
the brake pads or remove any ice coatings.
T he effec tiveness of the brakes can be red uce d
whe n the vehicle is d riven on a sa lt -covered
road and the b rakes are not used . Likewise,
yo u clean off acc umulated salt coat ing from
brake d iscs and pads with a few cautio us ap­
plicat ions o f th e b rake
c:> & .
Corrosion
The re may be a tendency for dirt to build up
on the brake pads and corros ion to form on
t h e d iscs if the car is not driven regu larly or
o n ly for short trips w ith litt le use of the
brakes .
If the brakes are not used frequently, or if cor­
ros ion has formed on the discs, it is adv isable
to clean off t he pads a nd d iscs by braking
firmly a few times from a moderately h igh
s p eed

Low brake fluid level
Malfunctions ca n occ ur in the bra ke system if
t h e b rake fluid level is too low. The brake flu id
level is monitored electronica lly.

154 Vehicle care and cleaning
Vehicle care and
cleaning
General information
Regular, proper care helps to maintain your
vehicle 's value. It can also be a requirement
when subm itting warranty claims for corro ­
sion damage and paint defects on the body .
The required cleaning and care products can be obtained from your authorized Audi dealer
or a qualified workshop. Read and follow the instructions for use on the packaging .
A WARNING
-Us ing cleaning and care products incor­
rectly can be dangerous to your hea lth .
- Always store cleaning and care products
out of reach of children to reduce the ris k
of poisoning.
@ For the sake of the environment
-Preferably use environmentally-friendly
products when buying cleaning agents .
- Do not d ispose of leftover cleaning and
ca re products with household trash .
Car washes
-
The longer that deposits such as insects, bird
droppings , tree sap or road salt rema in on the
vehicle, the more the surface can be dam­
aged. High temperatures such as those
caused by s unligh t increase the corrosive ef­
fect.
Before washing, wet heavy deposits with plen­
ty of water.
Also, wash the underside of your vehicle once
road salt stops be ing used for the season .
Pressure wa shers
When washing your vehicles with a pressure
washer, always follow the operating instruc­
tions provided w ith the pressure washer. Th is
is especially important in regard to the pres ­
sure and spray ing distance . Do not aim the
spray directly at seals on side w indows, doors, the
hood, the rear lid or the convertible top or
at tires, rubber hoses, insulating material
orsensors* . Keep a distance of at least 16 in ­
ches (40 cm) .
Do not remove snow and ice with a pressure
washer.
Never use rotary nozzles or high pressure noz­
zles.
The water temperature must not be above
140
°F (60 °() .
Automatic car washes
Spray off the vehicle before washing.
Make sure that the windows are closed and
the windshie ld wipers are off. Follow instruc­
tions from the car wash operator, especially if
there are accessories attached to your vehicle .
If possible, use car washes that do not have
brushes .
Washing by hand
Clean the vehicle starting from the top and
working down using a soft sponge or cleaning
brush . Use solvent-free cleaning products.
Washing vehicles with matte finish paint
by hand
To avoid damaging the paint when washing,
first remove dust and large particles from
your vehicle. Insects, grease spots and finger­
prints are best removed with a special cleaner
for matte finish paint .
Apply the product using a microfiber cloth. To
avoid damaging the paint surface, do not use
too much pressure.
Rinse the vehicle thoroughly with water. Then
clean using a neutra l shampoo and a soft mi ­
crofiber cloth.
Rinse the vehicl e thoroughly again and let it
air dry. Remove any water residue using a sham my.
Stubbo rn deposits such as bird droppings o r
tree sap are best removed with p lenty of wa-
ter and a microfiber cloth. .,.

Tires
General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . Tires are,
however, one of the most important parts of a
vehicle, particularly considering the compara­
tive ly small patch of rubber on each tire that
assures that a ll-impo rtant contact between
you, your vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry mo re weight than they can safe ly han­
d le, avoiding damage from road hazards and
reg ularly inspecting t ires for damage includ­
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separation and blowouts.
Avoiding damage I f you have to drive over a curb or similar ob­
stacle, drive very s low ly and as close as possi ­
b le at a right angle to the curb.
A lways keep chem ica ls includ ing gre ase, o il,
gasoline and b rake fluid off the ti res .
Inspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedded in the treads.
Storing tires Mark tires when you remove them to indicate
the direction of rotation . Th is ensures you to
be ab le to mount them correctly when you re­
install t hem.
When removed, the whee ls or t ires should be
stored in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims. New tire
s
New t ires have to be broken in¢&,. .
T he tread depth of new t ires may vary, accord­
ing to the type a nd make of t ire and the tread
pa tte rn .
Hidden damage
Damage to tires and r ims is ofte n not readily
vis ible . If you notice unusual v ibrat ion or the
vehicle p ulls to one side, th is may ind icate
t h at one of the t ires has been damaged . Th e
t ir es m ust be checked immed iate ly by an au ­
tho rized Aud i dea le r or q uali fied wor ks hop.
Unidirectional t ires
A un idirectional tire can be identified by ar­
rows on the sid ewa ll, that po int in the direc­
t ion the t ire is desig ned to rotate. You mus t
f ol low the specified d irection of rotation . This
is necessary so that these tires can develop
their optimum characterist ics regarding grip,
road no ise, wear and hyd rop laning resistance.

¢page 211.
A WARNING
-New tires or tires that are old, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
be broken in . To reduce the risk of losing
control, a co llision and ser ious personal
in jur ies, d rive w ith special ca re fo r the
fi rst 350 m iles (560 km).
- Driving with worn or damaged tires can
le ad to loss of control, sudden tire fail­
ure, including a blowou t and sudden de­
fl ation, c rashes and seriou s personal in­
juries . Have wo rn or damaged t ires re­
p laced immediate ly .
- T ires age even if they are not being used
an d can fai l sudden ly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith specia l care and at low
speed.
