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 road
without being distracted.
The driver is responsible for the safety of the
veh icle and a ll 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 us ing a cellular telephone.
.. NEVER drive when your driv 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 your speed to road, traffic
and weather condit ions .
.. 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
Impaired driving safety increases the risk
of serious personal injury and death when­
ever a vehicle is being used .
Driving Safely 91
Proper occupant
seating positions
Proper seating position for the driver
The proper driver seating position is impor­
tant for safe, relaxed driving.
Fig. 91 The correct d istance between d river a nd stee r­
in g 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
foll owing pos ition:
.,. Adjust the driver's seat so that you can easi­
ly push the pedals all the way to the floor
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. 91. If not possible, see your au­
thorized Audi dealership about adaptive
equ ipment .
.. Adjust the steer ing 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 wheel with
your elbow(s) slightly bent .
.. Adjust the head restraint so the upper edge
is as even as possible with the top of your
head . If that is not poss ible, try to adjust
the head restraint so that it is as close to
this position as possible .
.. Fasten and wear safety belts correctly
qpage 104.

A WARNING ,~
Heavy loads will influence the way your ve­
hicle handles. To help reduce the r isk of a
loss of control leading to ser ious personal
injury:
-Always keep in m ind when transporting
heavy objects, that a change in the cen­
ter of g ravity can also cause changes in
vehicle handling:
- Always distribute the load as even ly as
possible.
- Place heavy objects as far forward in
the luggage compartment as possible.
- Never exceed the Gross Ax le Weight Rat­
ing or the Gross Vehicle Weight Rating
specified on the safety compliance stick­
er on the left door jamb. Exceeding per­ missible we ight standards can cause the
vehicle to slide and handle differently .
- Please observe information on safe driv­
ing
i:> page 90.
A WARNING
To help prevent poisonous exhaust gas
from be ing drawn into the veh icle, always
keep the rear lid closed while dr iving.
- Never transport objects larger than those fitting completely into the luggage
area because the rear lid cannot be fully
cl osed.
- If you absolutely must drive with the rear
lid open, observe the follow ing notes to
reduce the risk of poisoning:
- Close all windows,
- Open all air outlets in the instrument
panel,
- Sw itch off the air recircu lation,
- Set the fresh ai r fan to the h ighes t
speed .
A WARNING
Always make sure that the doors, all win­
dows and the rear lid are securely closed
and locked to reduce the risk of injury
when the veh icle is not being used.
Dr iving S afel y 97
-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 o ut. Being trapped in a vehicle can
lead to serious personal injury.
- Never let ch ildren play i n or around the
veh icle .
- Never let passengers ride in the luggage
compartment. Vehicle occupants must
always be prope rly restra ined in one of
the vehicle 's seating pos it ions .
(D Tips
- Air circulation helps to reduce window
fogging. Stale a ir escapes to the outside
through vents in the trim panel, on the
left side of the luggage compartment. Be sure to keep these s lots free and
open.
- The tire pressure m ust 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.
The tire pressure label lists the recom­
mended co ld tire inflation pressures for
the vehicle at its maximum capacity
we ight and the tires that were on your
vehicle at the t ime it was manufactured .
For recommended tire pressures for nor­
ma l load cond itions, please see chapter
i=>page 200.
Tie-downs
The luggage compartment is equipped with
four tie-downs to secure luggage and other
items.
Use the t ie-downs to secure your cargo prop­
erly

partment .
In a collision, the laws of physics mean that
even smaller items that are loose in the vehi-
cle w ill become heavy missiles that can cause .,.

166 Cleaning and protection
sponges to prevent scratches. It is best
to use soapy water .
- You should remove debris (such as in­
sects) from the headlight lenses on a
regular basis, for example when refuel­
li ng your vehicle.
@ For the sake of the environment
On ly wash the vehicle in facilit ies specially
designed for that purpose. This w ill reduce
the risk of d irty water contaminated with
oil from entering the sewer system. In
some areas, washing vehicles outs ide of
these facilities is prohib ited.
Washing your vehicle with a power
washer
Cleaning the exterior of your car with a high­
pressure power washer is safe as long as you
observe a few simple rules.
• Before using the power washe r, make sure
you have read and understood the WARN­
I N GS 9 .&. in General information on
page 1 64.
• Always fo llow the opera ting ins truc tions for
the power washer.
• Make sure that the jet on the spray hose
produces a "fan shaped spray" .
• Do
no t ho ld the spray no zzle too close to
soft materia ls.
Keep a distance from soft materials such as
rubber hoses or insulat ing mater ial as we ll as
sensors and camera lenses.
When clea ning the vehicle wit h a power wash ­
er
always f o llow the operating instructions .
This applies particularly to the operating pres­
sure and the spraying distance. Do not po int
the spray directly at the sea ls around the s ide
windows, a round t he doors, on the rear lid or
on the su nroof* . Likew ise, do not point it di­
r e ctly at t ires, r ubber hoses, insul ation mate ­
rial or sensors. Hold t he sp ray noz zle at least
1.3 ft ( 0.4 m) away from the vehicle.
D o not use a h igh-pressure powe r washer to
r emove snow and i ce. D
o not use a jet which sprays water in a d irect
stream o r one that has a rotating jet .
Water temper ature sho uld n ot ex ceed 140 °F
(6 0 °C).
A WARNING ~ -
N eve r wash t ires wi th a jet that sprays wa­
ter i n a direct stream. This could cause in ­
v is ib le damage to the t ires and weaken
them, even if the spray is from a re lative ly
l ong distance and for a short time. Dam­
aged and weakened tires can fail a nd cause
a ccidents and pe rsonal i njury.
([) Note
To avoid damaging your vehicle, a lways
make sure that there is suffic ient d istance
between the spray head and soft materia ls
like rubber hoses, plast ic pa rts and sound­
deade ning ma ter ia ls as w ell as s ensors
and camera lenses. Neve r aim t he sp ray
head a t the same point fo r a long time.
This also applies to cleaning headligh ts
and painted bumpers. Remembe r: the
closer the nozzle is to the surface of the
materia l, the greater the stress on the ma ­
terial.
Caring for vehicles with matte finish
paint
Applies to vehicles: with matte finish paint
Vehicles with ma tte finish paint require spe­
cial care due to the characteristics of the
paint.
Wa shing by hand
To avoid damaging the paint when washing,
first remove dust and large par ticles from
your vehicle. Insects, grease spots and fi nger­
pri nts are best removed w ith a
special cleaner
for matte finish paint .
Apply the product us ing a microfiber cloth . To
avo id damag ing the pa int surface , do not use
too much pressure . ..,.

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.
For more information
¢page 227.
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.

-Never mount used tires on yo ur vehicle if
yo u 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.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .
