chains, make sure they will not drag on the
road when you are driving.
The cha ins shou ld cross under the trai le r
tongue to prevent it from dropping in case of
separation from the hitch.
(D Note
If you are going to tow a trailer, you must
activate the trailer operation mode
¢page 159, Towing a trailer.
Driving instructions
Driving with a trailer always requires extra
core and consideration.
To obtain the best poss ible handling of vehicle
and traile r, p lease note the following:
.,. Do not tow a loaded tra iler whe n your car it­
self is not loaded.
.,. Be especially careful when passing other
vehicles .
.. Observe speed limits.
.. Do not d rive at the maximum permissible
speed.
.. Always apply brakes early.
.. Monitor the temperature gauge.
Weight distribution
Tow ing a loaded trai ler with an empty ca r re­
sults in a high ly unstable distribution of
weight. If this cannot be avoided, drive at very
l ow speeds only to avoid the risk of losing
steering control.
A "balanced" rig is easier to operate and con ­
trol. This means that the tow vehicle should
be loaded to the extent possible and permiss i­
ble, while keeping the trailer as light as possi­
ble under the circumstances. Whenever possi­
ble, transfer some cargo to the luggage com­
partment of the tow vehicle wh ile observing
tongue load requirements and vehicle loading
considerations .
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig . Do not
drive at the maximum permissible speed. Re-
Trailer towing 243
duce your speed even more if load, weather or
wind conditions are unfavorable - particularly
when going downhill.
Red uce veh icle speed
immediately if the trail­
er shows the slightest sign of sway ing.
Do not
try to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds
f or vehicles towing trailers are lower than for
regular vehicles.
Always apply brakes early. When driving
downh ill, shift into a lowe r gear to use the en­
gine braking effect to slow the vehicle. Use of
the brakes alone can cause them to overheat
and fail.
Coolant temperature
The coolant temperature gauge¢ page 10
must be observed carefully. If the need le
moves close to the upper end of the scale, re­
duce speed immediately and/or turn off the
air conditioner.
If the coolant temperature warning light in
the instrument cluster starts flashing ., pull
off the road, stop and let the engine
idle for
about two minutes to prevent heat build -up .
A WARNING
Anyone not properly restrained in a mov­
ing vehicle is at a much greater risk in an
accident. Never let anyone ride in your car
who is not properly wearing the restraints
prov ided by Audi .
Trailer towing tips
Important to know
-
Your vehicle handles differently when towing
a trai ler because of the additional weight and
different weight distr ibution. Safety, perform­
ance and economy will great ly depend on how
carefully you load your trailer and operate
your rig.
Before you actua lly tow your tra iler, practice
turning, stopping and backing up in an area
away from traffic. Keep practicing until you
•
•

244 Trailer towing
have become comp lete ly familiar with the way
your vehicle-trailer combination behaves and responds.
Backing up is difficult and requires practice.
Backing up with a trai ler genera lly requires
steering action opposite to that when backing
up your veh icle without a trailer .
Maintain a greater distance be tween your ve­
hicle and the one in front of you. You will need
more room to stop. To compensate for the
trailer, you will need a larger than normal
turning radius.
When passing, remember that you cannot ac­
celerate as fast as you normally would be­
cause of the added load. Make sure you have
enough room to pass . After passing, allow
plenty of room for your trailer before chang­
ing lanes again .
Avoid jerky starts, sharp turns or rapid lane
changes.
- Do not tow a trailer during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re­
quire more freq uent maintenance due to
the extra load
c> page 325.
Parking on a slope
Do not pork on a slope with a trailer. If it can­
not be avoided, do so only after doing the fol ­
lowing:
When parking:
.. Apply the foot brake .
.. Have someone place chocks under both the
vehicle and the trai ler wheels .
.. With chocks in p lace, slowly re lease the
brakes until the wheel chocks absorb the
load .
.. Turn the wheels towards the curb .
.. Apply the parking brake .
.. Move the selector lever to
P.
When restarting after parking:
.. Apply the foot brake. ..
Start the engine.
.. Move the se lector lever to
D.
.. Release the parking brake and s low ly pull
out and away from the wheel chocks.
.. Stop and have someone retr ieve the wheel
chocks .
(D Tips
If you move the selector lever of the auto­
matic transmission to
P before applying
the parking brake and before blocking the
wheels, you may have to use more fo rce
l ater to move the lever out of the
P posi­
tion.

Cleaning and protect ion
General information
Regular core preserves vehicle value.
Any automobile is exposed to industrial
fumes , corrosive road salt, etc. A well cared
for Audi can look like new many years after purchase . Regu lar and correct care w ill con­
tr ibute to maintaining the beauty and value of
your Aud i.

Your authorized Audi dealer has a variety of
dedic ated veh icle-car e products and can ad ­
vise which ones to use for cleaning the exter i­
or and interior of your vehicle.
Whether you use products recommended by
Aud i or other commercially available clean ing
agents, please make sure you apply them cor­
rectly .
.&, WARNING
-Cleaning agents may be poisonous. Keep
them out of the reach of children.
- Heed all caut ion labels.
- Always read directions on the container
before using any product. Follow the di­
rect ions carefu lly.
- Most chemical cleaners are concentrated
and have to be diluted .
- Use spot removing fluids only in well
ventilated areas.
- Do not use gasoline, kerosene, d iesel
fuel, nail polish remover or other volatile
fluids. They may be toxic, flammab le or
haza rdous in other ways. Do not wash,
wax or dry the vehicle with the ign it ion
on or the engine running .
- Do not clean the undersides of chassis,
fenders, wheel covers, e tc. w ithout pro­
tecting your hands and arms. You may c u t yourself on sharp -edged metal parts .
Cleaning and protec tion 245
- Moisture and ice on brakes may impair
brak ing effic iency¢
page 228, General
information.
Test the brakes carefully
each time you wash the vehicle.
@) For the sake of the environment
Select on ly environmentally friend ly clean­
i ng products . Leftover cleaning products
should not d isposed of in the household
waste.
Care of exterior
Washing
Frequent washing protects the vehicle .
The best protection against environmental i n­
fluences is
frequent washing and waxing . How
often t his is required depends on:
- How much the veh icle is used
- Where the veh icle is parked (garage, in the
open under trees, etc.)
- The seasona l and weather conditions
- Environmental infl uences
T he longer b ird droppings, insects, tree resin,
road and indus tria l gr ime, ta r, soot, road salt
and other materials remain on the vehicle body, the more lasting their destructive ef­
fects wi ll be . High temperatures caused by ex­
posure to intense sun light intens ify the corro­
s ive effect, particularly when humid ity is high
as well.
Under certain circumstances,
weekl y washing
may be necessary. Under other cond itions, a
monthly washing and waxing may be ade­
quate .
After the winter, the underside of the vehicle
should be thoroughly washed, preferab ly in a
professional car wash .

directly at locks, or at door or hatch
openings -they can freeze shut.
- Never use sponges designed to remove
insects , or any kitchen scouring sponges
or similar products. They can damage
your paint finish .
- You should remove debris (such as in­
sects) from the headlight lenses on a
regular basis, for example when refuel­
ing your vehicle. Never use a dry cloth or
sponge to clean the headlights . Only use
wet cloths or sponges to prevent
scratches . It is best to use soapy water .
@) For the sake of the environment
In the interest of the environment, the ve­
hicle should only be washed in special
wash bays .
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 observ e a few simple rules.
" Before using the power washer , make sure
you have read and understood the WARN­
INGS ~.&.
in General information on
page 245.
" Always follow the operating instructions for
the pow er wash er.
" Make su re that the jet on the spray hose
produces a "fan shaped spr ay" .
" Do
not hold the spray nozzle too close to
soft materials .
When cleaning the vehicle with a power wash­
er
always follow the operating ins truc tions.
T his applies particularly to the
operating
pressure
and the spraying distance. Maintain
a sufficient distance to soft materials such as
rubber hoses and sound/vibration deadening
materials (particularly on the underside of the
engine hood). Do not use a jet which sprays
water in a
direct stream or one that has a ro­
tating
jet.
Water temperature should not exceed 140 °F
(60 °().
Cleaning and protection 247
A WARNING
Never wash tires with a jet that sprays wa­
ter in a direct stream . This could cause in­
visible damage to the tires and weaken
them, even if the spray is from a relatively
long distance and for a short time . Dam­
aged and weakened tires can fail and cause
accidents and personal injury.
(D Note
To avoid damaging your vehicle, always make sure that there is sufficient distance
between the spray head and soft materials
like rubber hoses, plastic parts and sound­
deadening materials. Never aim the spray
head at the same point for a long time.
This also applies to cleaning headlights
and painted bumpers. Remember : the
closer the nozzle is to the surface of the
material, the greater the stress on the ma­
terial.
Sensors and camera lenses
- Remove snow with a hand brush and remove
ice with a de-icing spray that does not con­
tain solvents.
- Clean the sensors (adaptive cruise control*,
parking system*) with a cleaning solution
that does not contain solvents and a soft
cloth.
- Dampen the camera lens with a household
alcohol-based glass cleaner, and then wipe
the lens clean with a dry cloth.
(D Note
- If you wash your vehicle with a pressure
washer,
- make sure there is enough distance to
sensors in the rear bumper .
- do not clean the camera lenses and the
area around them with the pressure
washer .
- Never use warm or hot water to remove
snow or ice from the camera lens. This
could cause the lens to crack .

Engine compartment
Be especially careful when cleaning the en­
gine compartment.
Al ways s witch off the ign ition befor e clean ­
ing the eng in e
c:> & .
Plenum panel
Remove leaves from the plenum pane l in front
of the windshield under the engine hood. This
prevents the water drain holes from becoming
blocked, and it prevents debris from entering
the vehicle interior through the heating and
ventilation ducts .
Corrosion protecti on
The engine compartment and transmission
have been corrosion-protected at the factory.
Good anti-corrosion treatment is very impor ­
tant, particular ly in the winter . If the vehicle
is frequent ly driven on salt treated roads, the
entire engine compartment and plenum panel
should be thoroughly cleaned at the end of
winter and retreated to prevent sa lt damage.
At the same time, the underside of the vehicle
should be washed as we ll.
If the engine compartment is cleaned at any
time with grease removing solut ions
1>, or if
you have the engine washed, the anti-corro­
sion treatment is a lmost always removed as
well.
It is therefore essential to have a long­
lasting co rrosion protection reapp lied to a ll
surfaces, seams, joints and components in the
engine compartment.
A WARNING
Be aware: The engine compa rtment of any
motor vehicle is a potentially hazardous
area.
- Before working in the engine compart­
ment, be s ure to read the in format ion
c:> page 264.
- Before reaching into the front plenum
pane l, always remove the ignition key.
l) Use only the correct cleaning sol utions. Never use gas­
oline or diesel fuel.
Cleaning and protec tion 255
Otherwise, the windshield wiper system
could un intentionally be switched on,
possibly caus ing personal injury from the
mov ing wiper linkage.
- Never reach into the area around or
touch the radiator fan. The aux iliary fan
is temperature controlled and can sw itch
on suddenly - even when the ignition is
off.
- Do not wash, wax or dry the eng ine with
the engine running. Moving or hot parts could injure you.
- Do not clean the underside of the chas­
sis, fenders, wheel covers, or other ha rd
to reach pa rts without protect ing your
hands and arms. You may cut yourself on
sharp-edged metal parts .
- Always read and heed all WARNINGS and

- If you experience a loss of fuel economy
or driveability and performance prob­ l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
Applies to vehicles : wit h gasoli ne e ng in e
A majo r concern among many auto manufac­
ture rs is carbon deposit build-up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another , they have certain
things in common. All gasoline g rades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline
Fuel supply and filling your fuel tank 257
brands include additives to keep engine and
fuel systems clean, they are not equally effec­
tive .
Audi recommends using TOP TIER Detergent
Gasoline . For more information on TOP TIER
Detergent Gasoline, please go to the official
webs ite (www.toptiergas.com).
After an extended per iod of using inadeq uate
fuels, carbon deposit build-ups can rob your
engine of peak performance.
(D Note
Damage or malf unct ion due to poor fuel
quality is not covered by the Audi New Ve­
hicle Limited Warranty.
Diesel fuel
Applies to veh icles: w ith diesel engine
Always use ULSD (Ultra Low Sulfur Diesel) sul­
fur content 15 ppm or less.
The ULSD (U ltra Low Sulfur Diesel) meets the
ASTM-D-97S (grade 2).
Die sel fuel with a higher concentration than
ULSD-Die sel No. 2 ASTM D975 and Bio-die­
sel with a higher concentration than 5
% like
Bl 1 , B20 or B100 are strictly prohibited.
Service station fue l pumps are labeled with
the correct fuel information for easy recogni­
tion by the user. If the diesel fuel pump is not
labeled ask the station operator what fuel is
being dispensed before filling up your vehicle.
Serv ice stations offering Diesel fuel are gener ­
ally located on truck routes or major high­
ways . Directories of Diesel fuel stations are
usually available at Diese l fuel stations.
Some states in the USA require permits to
purchase Diesel fuel. Check with your State

Winter operation
At temperatures below 20° F (-7° C), Diesel
fuel No.
2 loses its fluidity due to wax separa­
tion, which may clog the fuel filter or tank fil­
ter and keep the engine from running .
To help the filter from being clogged by wax,
the fue l filter in your vehicle is automatically
preheated. Preheating the fuel filter makes
operation of your vehicle possible with Diesel
fuel No. 2 down to -10° F (-24° C).
If you expect temperatures below
5° F
(-15° C)
ask your fuel dealer whether their
Diese l fuel No.
2 is sufficiently winterized for
the prevailing and expected temperatures.
If not winterized or insufficiently winterized
Diesel fuel has already thickened to the extent
that the engine will not start, warm the vehi­
cle up by leaving it in a heated garage.
It is normal that the engine noise leve l (die­
seling) is louder during the warm-up period in
winter. It is also norma l when whitish-blue
smoke comes out of the tailpipe after starting
and during warm-up . The amount of smoke
depends on the outs ide temperature.
Do not let your Diese l engine idle unnecessari ­
ly after a cold start. Driving off slowly will
shorten the warm-up period.
A WARNING
- Never use "starting assist fluids." They
may be potent ially explosive or cause a
"run-away" engine condition. This could
result in ser ious engine damage and per­
sonal injur y.
- Never use fuel line anti-freeze offered for
gasoline engines.
(D Note
- Your Diesel engine has been specifically designed to operate only on Ultra Low
Sulfur Diesel fuel. Therefore, never use
home heating oil or regular gasoline. The
properties of these fuels may cause seri­
ous damage to the fuel injection system
and to the engine. Using these fuels can
-
cause expensive engine repairs and will
also adversely affect your New Vehicle
Limited Warranty.
- If Diesel fuel sho uld get on any rubber
hose, it must be wiped off immediately.
Then wash the contaminated hose por­
tion with soap and warm water. Do not allow D iesel fuel to remain on connect­
ing hoses . They may develop leaks and
cause serious damage.
