206 Driving and en vir onm ent
Driving through water
on roads
Note the following to avoid vehicle damage
when driving thro ugh water, for example on
flooded roads:
- The wate r must not be any higher than the
bottom of t he vehicle body.
- Do not drive faster than wa lking speed.
A WARNING
After driving through wate r, mud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
sto re the full braking effect.
@) Note
- Vehicle components such as the eng ine,
transmission, suspension or electr ical
system can be severely damaged by driv­ i ng th rough water.
- Always switc h off the Start-Stop-System
when driving through water~
page 80 .
(1) Tips
-Check the depth of the water before dr iv­
i ng th rough it.
- Do not stop the ve hicle, dr ive in reverse
or switch the engine off whe n driving
t hr ough water .
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep fo r you r vehi­
cl e to drive th rough safely.
- Avoid dr iving through salt water because
i t can cause corrosion.
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels.
Fuel economy, environmenta l impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal driving style
- oper ating conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economica lly, you can easily cut your
fuel consumpt ion by 10-15 percent . This sec­
t ion w ill give you some tips on how you can
help the env ironment and your pocketbook.
@ Tips
The consumption estimates as published
by ENVIRON MEN TAL PROTEC TION AG ENCY
( EP A) and Transpo rt Canada may no t corre­
spond to your actual consump tion on the
r oad, which will va ry depending upon vehi ­
cle load and speed, road and weather con ­
ditions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.,. Avoid unnecessary accelerating and braking.
Vehicles use the mos t fu el when they are ac­
ce le rat ing. If yo u ant icipate what is going to
happen next, you will need to brake less and,
t hu s, acce le rate less . Let the vehicle coast
whenever possible -for examp le when you see
t h at the next traff ic light is red.

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
ing your vehicle. Never clean the head­
lights w ith a dry cloth or sponge. Use a
wet cloth or sponge. It is best to use
soapy water .
@ For the sake of the environment
Only wash the vehicle in facilit ies specially
designed for that purpose. Th is w ill reduce
the risk of d irty water contaminated with
oil from entering the sewer system . In
some areas, washing veh icles outs ide of
t hese facilit ies 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 .
.,. Befo re using the power washe r, make sure
you have read and understood the WARN­ INGS ¢
A. in General information on
page 213.
.,. Always fo llow the operating instructions for
the power washer .
.,. Make sure that the jet on the spray hose
produces a "fan shaped spray" .
.,. Do
not ho ld the spray no zzle too close to
soft mate ria ls .
Keep a d istance from soft materials such as
rubber hoses or insulat ing mater ial as we ll as
sensors and camera lenses .
When clean ing the vehicle w it h a power wash­
er
always follow the operating instructions.
This applies particularly to the operating pres­
sure and the spraying distance . Do not po int
the spray directly at t he sea ls around the side
windows, aro und the doors, o n the rea r lid or
on the sunroof *. L ikew ise, do not point it di­
rectly at tires, r ubber hoses, ins ulation mate­
rial or sensors ¢
page 216. Hold the spray
Cleaning and protec tion 215
nozzle at least 1.3 ft (0.4 m) away from the
vehicle.
Do no t use a high-p ressure power w asher to
remove snow and ice .
Do not use a jet which sprays wate r in a d irect
stream o r one that has a rotating jet.
Water temperature should not exceed 140 °F
(60 °() .
A WARNING
Neve r wash t ires with a jet that sprays wa­
ter in a direct stream . Thi s could cause in­
v isible damage to the t ires and we aken
them, even if the spray is from a re lative ly
l ong dis tance and for a short time. Dam ­
aged and wea kened tires can fail and cause
accidents and personal in jury.
(D Note
To avoid damaging yo ur vehicle, a lways
make sure tha t the re is sufficien t distance
between the s pray head and soft materia ls
lik e rubber hoses, plastic parts and sound­
deaden ing mater ia ls as well as sensors
and camera lenses. Never a im t he spray
head at the same point for a long time .
This also applies to cleaning headlights
and paint ed bumpers. Remembe r: the
closer the no zzle is to the surfa ce of the
m at eria l, the gre ater the s tress on the m a­
terial.
Caring for vehicles with matte finish
paint
App lies to vehicles : wit h matte finish paint
Vehicles with matte finish paint require spe ­
cial care due to the characteristics of the
paint.
Washing by hand
T o avoid d amaging the pain t when washing,
first remove dust and la rge particles from
your vehicle . Insects, grease spots and finger­
prints are best removed with a
special cleane r
for matte fin ish paint .

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 all -important contact between
you, your vehicle and the road.
Maintaining the correct tire pressure, making
sure that your vehicle and its tires do not have
to carry more 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 overall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separation and blowouts.
A vo idin g dama ge
I f you have to drive over a curb or similar ob­
stacle, drive very slow ly and as close as possi ­
ble at a right angle to the curb.
A lways keep chem icals including grease, oil,
gasoline and b rake fluid off the tires.
Inspect the tires regularly for damage (cuts,
cracks or bl isters, etc.). Remove any foreign
bod ies embedded in the treads.
St orin g tire s
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 them.
When removed, the wheels or tires should be
stored in a cool, dry and preferably dark place .
Store tires in a vertical position if they are not mounted on rims, in a horizontal position if
they are mounted on rims. N
ew tir es
New t ires have to be broken in¢&,. .
The tread depth of new t ires may vary, accord­
ing to the type and make of t ire and the tread
pattern .
Hidden damag e
Damage to tires and r ims is often not readily
vis ible . If you notice unusual vibrat 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
t ir es must be checked immed iate ly by an au­
tho rized Aud i dea le r or q ualified wor kshop.
Unidirecti onal t ires
A un idirectional tire can be identified by ar­
rows on the sidewall, that po int in the direc­
t ion the t ire is designed to rotate. You must
fol low the specified direction of rotation . This
is necessary so that these tires can develop
their optimum characteristics regarding grip, road noise, wear and hydrop laning resistance.
For more information
¢ page 274.
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 collision and ser ious personal
injuries, drive w ith special ca re for the
fi rst 350 m iles (560 km).
- Driving with worn or damaged tires can lead to loss of control, sudden tire fail­
ure, including a blowou t and sudden de­
flation, c rashes and serious personal in­
juries . Have worn or damaged tires re­
p laced immediate ly .
- Tires age even if they are not being used
and 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 special 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 .

was manufactured, and the last four numbers
represent the week and year of manufacture.
For example,
DOT ... 2212 ...
means that the tire was produced in the 22nd

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.
Fi g. 196 Tire pressure label: located on drive r's si de 8 -
pilla r
Tire pressure gene ra lly refers to the amo unt
of air i n a tir e th at i t needs it to do its job and
s a fe ly c arry the combined load of the entire
ve hicl e and its contents . Tire pressure is
measured in kilopasca ls (kPa), the i nterna ­
tional measuring unit and in pounds per
squa re inc h (PSI). Tire pressure is based in
part o n the vehicle's design and load limit -
the greatest amount of we ight that the vehi ­
cle can car ry safely an d the t ire s ize. The prop­
e r tire p ressu re is freq uen tly referred to as the
"recommende d cold tire inf lation pressure."
A ir in the tires exp ands when the ti re heats up
beca use of in ter nal fri ct ion when i t flexes in
use. The tire p ress ure is higher when the tire
has warmed up tha n when it is "cold." It is the
inflat ion pressure in a "cold" tire that counts.
Therefore, you sho uld never let air out of a
warm tire to match "cold ti re inflation pres­
sure" recommendations. The t ires wo uld the n
be underinflated a nd could fail suddenly .
Maintaining proper t ire p ressure is one of the
most important things you can do to he lp
avoid sudden tire failure. Underinflated t ires

Tire pres­
sures are particularly important when the
vehicle i s being dr iven at higher speeds, and
then especially when heavily loaded even
within the permissible load-carrying capaci ­
ties approved for your vehicle .
The recommende d tire pressures for your Audi
depen d on t he kind of tires o n your vehicle
and the number of passengers and/or amount
of luggage you w ill be transporti ng.
T he tire pressure label is located on the d riv­

the recommended cold t ire inflat ion pressures
fo r the vehicle at its maxim um capac ity
weight and tires t hat were on your veh icle at
t h e time it was ma nufactured.
If you wish to improve comfort when operat­
ing the vehicle at normal load (up to 2 /3*
occupants ), you can adjust t ire pressures to
those specified for normal vehicle load. Be·
fore operating the vehicle at maximum load,
you mu st increase the tire pres sures to those
specified for maximum vehicle load
