partment and use suitable straps, partic­
ularly with heavy objects.
- When you transport heavy objects, al­
ways remember that a change in the cen­
ter of gravity may result in a change in
the vehicle's handling characteristics .
- Follow all warnings
q page 121, Driving
safety.
(D Tips
The tire pressure must be adjusted to the
load -see the tire pressure sticker located
on the driver's side B-pillar.

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 respons ible for the safety of the
vehicle and all of its occupants.
If your ability
to drive is impa ired, safety r isks for everybody
in the vehicle increase and yo u also become a
hazard to everyone else on the road
r:::;, &,.
Therefore:
• Do not let yourself be dis tracted by passe n­
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, traffic
and weather condit ions .
• Take frequent breaks on long trips . Do not
dr ive for more than two hours at a stretc h.
• Do NOT drive when you are t ired, under
pressure or when you are st ressed.
A WARNING
-Impaired dr iving safety increases the risk
of ser ious 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 . 109 Correct seat ing posit ion
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
following position:
.,. 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
r:::;,A .
.,. 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.
• Adj ust 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
c:::> fig. 109 . 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 .
• For adjustable head restraints: Adjust the
head restraint so the upper edge is as even
as possible with the top of your head. If that..,_

128 Driving safety
-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 121.
A 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
those fitting completely into the luggage
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 power roof",
- Open all air outlets in the instrument
panel,
- Switch off the air recirculation,
- Set the fresh air fan to the highest
speed.
A WARNING
Always make sure that the doors, all win­
dows, the power roof* 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 luggage compartment
lid left open. A child could crawl into the
vehicle through the luggage compart­
ment 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. 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.
The tire pressure label lists the recom­
mended cold tire inflation pressures for
the vehicle at its maximum capacity
weight and the tires that were on your
vehicle at the time it was manufactured.
For recommended tire pressures for nor­
mal load conditions, please see chapter
~ page 229.
Tie-downs
The luggage compartment is equipped with
four tie-downs to secure luggage and other
items.
Use the tie-downs to secure your cargo prop­
erly ~
page 12 7, Loading th e luggage com­
par tment.
In a collision, the laws of physics mean that
even smaller items that are loose in the vehi­
cle will become heavy missiles that can cause
serious injury. Items in the vehicle possess en­
ergy which vary with vehicle speed and the
weight of the item . Vehicle speed is the most
significant factor.
For example, in a frontal collision at a speed
of 30 mph (48 km/h), the forces acting on a 10-lb (4 .S kg) object are about 20 times the
normal weight of the item . This means that
the weight of the item would suddenly be about 200 lbs. (90 kg). You can imagine the
injuries that a 200 lbs. (90 kg) item flying ..,_

Make sure that the cooling system has enough
f luid .
Tire pressure
When tow ing a trai ler, inflate the t ires of your
veh icle to the cold tire pressure listed under
"Full load" on the label located on the driver's
side B-pillar (visible when the door is open) .
Inflate trailer tires to trai ler and tire manufac­
turers' specifications.
Lights
Check to make sure both veh icle and trailer
lights are working properly.
Safety chains Be sure tra iler safety cha ins are properly con­
nected from the trailer to the hitch on the ve­
hicle. Leave enough slack in the chains to per­
mit turning corners . When you install safety
chains, make sure they wi ll not drag on the
road when you are driving.
The chains should cross under the trailer
tongue to prevent it from dropping in case of
sepa ration from the hitch.
Driving instructions
Driving with a trailer always requires extra
care and consideration.
To obta in the best poss ible handling of vehicle
and trai le r, p lease note the following:
.. Do not tow a loaded tra iler when your car it ­
self is not loaded .
.. Be especially carefu l when passing other
vehicles.
.. Observe speed limits.
.. Do not drive at the maximum permissible
speed .
.. Always apply brakes early.
.. Monitor the temperature gauge.
Weight distribution
Tow ing a loaded trailer with an empty ca r re­
sults in a high ly unstable distribution of
weight . If this cannot be avoided, drive at very
Trailer towing 199
low speeds on ly to avoid the risk of losing
steering contro l.
A "balanced " rig is easier to operate and con­
trol. This means that the tow vehicle should
be loaded to the extent possible and permissi­
ble, while keeping the trailer as light as possi­
ble under the c ircumstances. Whenever poss i­
ble, transfer some cargo to the luggage com­
partment of the tow vehicle while observing
tongue load requirements and vehicle loading
considerations.
Speed
The higher the speed, the more difficu lt it be­
comes for the driver to control the rig. Do not
drive at the maximum permissible speed. Re­
duce your speed even more if load, weather or
wind conditions are unfavorable -particularly
when going downhill .
Reduce vehicle speed
immediately if the trail­
er shows the slightest sign of swaying .
Do not
try to stop the swaying by accelerating .
Observe speed limits. In some areas, speeds
for vehicles towing tra ilers are lower than for
regular veh icles .
Always apply brakes early. When driving
downhill, shift into a lower gear to use the en­ gine braking effect to slow the vehicle . Use of
the brakes alone ca n cause them to overheat
and fail.
Coolant tempe rature
The coo lant temperature gauge¢
page 12
must be observed carefully. The coolant tem­
perature can increase if you drive on long in­
cli nes in a low gear at high engine speeds . Re ­
duce your speed immediately if the LEDs in
the top part of the display turn on.

A WARNING
Anyone not properly restrained in a mov­
ing vehicle is at a much greate r risk in an
accident. Never let anyone ride in yo ur car

care products with household trash.
Car washes
T he longer that deposits such as insects, bird
droppings, tree sap or road sa lt rema in on the
veh icle, the more the surface can be dam­
aged . High tempe ratures such as those
caused by sunlight increase the cor rosive ef­
fect .
Before washing, rinse off heavy depos its with
p lenty of water .
Also, was h the underside of your ve hicle once
road salt stops be ing used for the season.
P ressure wash ers

Tires and wheels
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
veh icle, particularly considering the compara­
tively small patch of rubber on each tire that
assures that a ll- important 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 safely han­
d le, avoiding damage from road hazards and
r eg ularly inspect ing t ires for damage includ­
ing cuts, slashes irregu la r wear and overall
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 If you have to d rive over a curb or similar ob­
stacle, drive very slow ly and as close as possi ­
b le at a right angle to the curb.
A lways keep chemicals includ ing grease, o il ,
gasoline and brake fluid off the t ires .
I nspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedde d in the treads.
Storing tires Mark t ires when you remove them to indicate
the direction of rotation . T his ensures you to
be ab le to mount them correctly when you re­
i nstall them .
When removed, the whee ls or t ires should be
sto red 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 ition if
they are mounted on rims .

The 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.
H idden damage
Damage to tires and rims is ofte n not readily
visible . If you notice unusual v ib rat ion or the
vehicle pulls to one s ide, th is may ind icate
that one of the t ires has been damaged . T he
ti res m ust be chec ked immed iate ly by an au­
thorized Audi dea le r or q ua lified wor kshop .
Unidirectional tires
A un idirectional tire can be identified by ar­
rows on the sidewa ll, that po int in the direc­
tion the t ire is designed to rotate. You mus t
f ol low the specified di rection o f rotation . T his
is necessary so that these tires can develop
their optimum characteristics regarding grip, road noise, wear and hydrop laning resistance.
For more information
¢page 253.
A WARNING
New tires or t ires that are old, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
also be b roken-in. To reduce the risk of
losing control , a collision and serious
pe rsonal injuries, drive w it h special care
for the first 350 miles (560 km).
- Driving with worn or damaged tires can
lead to loss of control, sudden tire fail­
ure, including a blowout and sudden de­
fl ation, cras hes and se riou s personal in­
juries . Have wo rn or damaged t ires re­
placed immediate ly.
- Ti res age even if they are not being used
and can fai l sudden ly, especially at hig h
spee ds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith special care and at low
speed.
