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 respons ible for the safety of the
vehicle 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
c:> .&,..
Therefore:
.. Do not let yoursel f be distracted by passen
gers or by using a cellular telephone .
.. NEVER drive when your driving ability is im
paired (by medications, alcohol, drugs, etc.).
.. Observe all traffic laws, rules of the road
and speed limits and plain common sense .
.,. ALWAYS adjust your speed to road, traff ic
and weather cond it ions .
.. Take frequent breaks on long t rips. Do not
drive for more than two hours at a stretc h.
.. Do NOT drive when 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.

mend that you adjust the driver's seat to the
follow ing pos ition:
.. Adjust the driver's seat so that you can easi
ly push the pedals all the way to the floor
wh ile keeping your knee(s) slightly bent
c:> .&,. .
.. Adjust the angle of the seatback so that it is
in an upr ight position so that your back
comes in full contact with it when you drive .
.. Adjust the steering wheel so that th ere is a
distance of at least 10 inches (25 cm) be
tween the steering wheel and yo ur breast
bone ~

thorized Audi dealer about adaptive equip
ment .
.. 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 steer ing whee l with
your elbow(s) slightly bent.
.. Adjust the head rest raint 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 .

to the backrest on the vehicle seat. Ad
just or remove the rear seat head restraint if it is difficult to install the
child seat with the head restraint in place
<=> page 78 . Install the head restraint
again immediately once the child seat is
removed. Driving without head restraints
or with head restraints that are not prop erly adjusted increases the risk of serious
or fatal neck injury dramatically.
- Always read and heed all WARNINGS
whenever using a child restrained in ave
hicle is being used<=>
page 174, Safety
belts,
<=> page 183, Airbag system and
i=> page 204, Important things to know.
A WARNING
If exceptional circumstances require the
use of a forward-facing child restraint on
the front passenger's seat, the child's safe
ty and well-being require that the follow ing special precautions be taken:
- Make sure the forward-facing seat has
been designed and certified by its manu
facturer for use on a front seat with a passenger front and side airbag.
-A lways follow the manufacturer's in
structions provided with the child safety
seat or infant carrier.
- Always move the front passenger seat in
to the rearmost position of the passen
ger seat's fore and aft adjustment range, and as far away from the airbag as possi
ble before installing the child restraint.
- Always make sure that nothing prevents
the front passenger's seat from being
moved to the rearmost position in its
fore and aft adjustment range.
- Always make sure the backrest is in an
upright position.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched
on.
- If the light does not stay on, perform the
checks
<=> page 194, Monitoring the Ad
vanced Airbag System.

Booster seats and safety belts
Properly used booster seats can help protect
children weighing between about 40 lbs. and
80 lbs. (18 kg and 36 kg) who are less than 4
ft.
9 in . (57 inches/1 .45 meters) tall.

Fig. 219 Rear seat: c hild properly restrained in a boos
te r seat
The vehicle 's safety belts alone will not fit
most children until they are at least 4 ft. 9 in .
(57 inches/1.45 meters) tall and weigh about
80 lbs. (36 kg). Booster seats raise these chil
dren up so that the safety belt will pass prop
erly over the stronger parts of their bodies
and the safety belt can help protect them in a
crash.
.,. Do not use the convertible locking retractor
when using the vehicle's safety belt to re
strain a child on a booster seat.
.. The shoulder belt must lie as close to the
center of the child's collar bone as possible
and must lie flat and snug on the upper
body. It must never lie across the throat or
neck . The lap be lt must lie across the pelvis
and never across the stomach or abdomen .
Make sure the belt lies flat and snug. Pull on
the belt to tighten if necessary .
.,. If you must transport an older child in a
booster seat on the front passenger seat,
you can use the safety belt height adjust
ment to help adjust the shoulder portion
properly.

Weight Rating will also change the per
formance and handling characteristics of
your vehicle, which could cause a crash resulting in serious injury or death .
- The Gross Vehicle Weight Rating for your
vehicle would be exceeded if your vehicle
is simultaneously equipped with Panor
amic sliding sunroof; third-row seating;
trailer towing equipment (factory or
dealer-installed), and running boards
(dealer-installed) . UNDER NO CIRCUM
STANCES MAY ALL SUCH ITEMS BE IN
STALLED ON THE SAME VEHICLE.

mum 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
For best vehicle handling under these
changed cond itions, adjust the trailer load so
that the tongue load is at the maximum al
lowable or slightly lower. You can get an ap
proximation of the tongue load with 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 hitch Trailer towing 241
may not exceed 662 lbs (300 kg). With an
af
termarket

the distance between the guide rails of
the facility -there is a risk of damage to
the wheels and tires .
- Compare the height and width of your
vehicle with the he ight and width of the
tunnel at the fac ility. -
To prevent paint damage, do not wash
the vehicle in direct sunlight.
- T o reduce the r isk o f damage to the sur
face, do not use insect removing spong
es, kitchen sponges or similar items.
- Matte finish painted vehicle compo nents:

284 Tires and wheels
All-wheel drive
Vehicles with quattro must always have tires
of the same size , construction and tread type.
For details see Qpage 228.
~ WARNING
Sudden tire failure can lead to loss of con
trol, a crash and serious persona l 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 tires .
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires 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 a re 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.
New tires and replacing tires and wheels
New tires and wheels have to be broken in .

snow cha in manufacturer when doing so .
- If the Adaptive Air Suspension* should
malfunction, do not mount or use snow
chains because the vehicle will be ex
tremely low. If you do dr ive with snow
chains on while the vehicle is at this lev
el, the snow chains might severely dam

the veh icle.
(!) Tips
Where snow cha ins are mandatory oncer
tain roads, this normally also applies to
veh icles with all-whee l dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the
factory installed r ims. If different rims are fit
ted, the correct wheel bolts with the r ight
l ength and correctly shaped bolt heads must
be used. This ensures t hat wheels a re fitted
secure ly and that the brake system f unctions
correctly .
I n ce rtain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same mode l
<=?page 318.
.&_ WARNING
Improperly tightened o r maintained wheel
bolts can become loose ca using loss of
contro l, a co llision and serious persona l in
jury.
- Always keep the wheel 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 bo lts and
the threads in the wheel hubs. They can
become loose w hile driving if greased or
oiled, even if tightened to the specified
torque. -
On ly use wheel bolts that be long to the
rim being installed .
- Never use different wheels bolts on yo ur
veh icle.
- Always maintain the correct tightening
torque for the whee l bolts to reduce the
risk of a whee l loss. If the tightening tor
que of the wheel bolts is too low, they
can loosen and come out when the vehi
cle is mov ing. If the tightening torque is
too high, the wheel bolts a nd threads
can be damaged and the whee l can be
come loose.
(D Note
The specified torque for the wheel bolts is 120 ft lb ( 160 Nm) with a to le rance of
± 7,4 ft lb( ± 10 Nm) . T orque wheel bolts
