___ T_ r _a_ il_e _r_ t_ o_ vv_ in__... g,_ __________________________________________________ _
Observe speed limits. In some areas, speeds for vehicles towing
trailers are lower than for regular vehicles.
Always apply brakes early. When driving downhill, shift into a lower gear to use the engine braking effect to slow the vehicle. Use of the
brakes a lone can cause them to overheat and fail.
Coolant temperature
The coolant temperature gauge=> page 8 must be observed care­
ful ly . If the needle moves close to the upper end of the scale, reduce
speed immediately and/or turn off the air conditioner .
If the coolant temperature warning light in the instrument cluster
starts flashing
-F- , pul l off the road, stop and let the engine idle for
about two minutes to prevent heat build-up .
& WARNING
Anyone not properly restrained in a moving vehicle is at a much
greater risk in an accident. Never let anyone ride in your car who
is not properly wearing the restraints provided by Audi . •
Trailer towing tips
Important to know
----------------
Your vehicle handles differently when towing a trailer because of
the additional weight and different weight distribution. Safety,
performance and economy will great ly depend on how careful ly you
load your trailer and operate your rig.
Before you actual ly tow your trailer, pract ice turning, stopping and
backing up in an area away from traffic. Keep practicing unti l you
have become completely familiar with the way your vehicle -trailer
combination behaves and responds . Backing
up is difficult and requires practice . Backing up with a
t rai ler genera lly requires steering action opposite to that when
backing up your vehicle without a trailer .
Maintain a greater distance between your vehicle and the one in
front of you. You will need more room to stop . To compensate for
the trai ler, you wi ll need a larger than norma l turning radius.
When passing, remember that you cannot accelerate as fast as you
normally would because of the added load. Make sure you have
enough room to pass. After passing, al low plenty of room for your
trai ler before changing lanes again .
Avoid jerky starts, sharp turns or rapid lane changes.
[ i ] Tips
• Do not tow a trailer during the break -in period of your vehicle.
• If you tow a trailer, your Audi may require more frequent mainte­
nance due to the extra load=>
page 339. •
Parking on a s•ope
Do not pork on a slope with a trailer. If it cannot be
avoided, do so only ofter doing the following:
When parking:
Apply the foot brake.
- Have someone p lace chocks under both the vehicle and
the trailer wheels.
With chocks in place, slow ly release the brakes until the
wheel chocks absorb the load.
- Turn the wheels towards the curb.
- Apply the parking brake.

Cleaning and protection
General information
Regular ca re p rese rves vehicle value .
Any automobile is exposed to industrial fumes, corrosive road salt ,
muddy dog feet, e tc. A wel l cared fo r Audi can look l ike new many
years after purchase . Regu lar and correct care will contribute to
maintaining the beauty and va lue of your Audi .
Fu rthe rmo re , g ood care ma y be a conditi on for sub sta ntiating a
warr anty cla im should corro sion damage or paint defect s occur .
Your authorized Audi dealer has a var iety of dedi cat ed vehicle -care
product s
and can advise which ones to use for cleaning the exterior
and interio r of your vehicle.
Whether you use products recommended by Audi or other commer ­
cially availab le cleaning agen ts, please make su re you apply them
correctly .
& WARNING
• Cleaning agents m ay be poi sonou s. Keep them out of the re ach
of childr en.
• Heed all cau tion label s.
• Alway s read direction s on the container before u sing any
produ ct. Follo w the dire ction s carefull y.
• Most chemi cal cle aner s are concentr ated and h ave to be
d iluted .
• Use spot remo ving fl uid s onl y
in well ventila ted are as.
• Do not use gasoline , kero sene , diesel fuel , nail poli sh remover
or other vol atil e fluid s. They may be to xic , fl ammab le or h azardou s
in other wa ys. Do not wa sh , wax or dry the vehicle w ith the igni ­
tion on or the engine ru nning .
& WARNING (continued )
• Do not clean the unders ide s of cha ssi s, fenders , wheel cover s,
et c. without pr ote cting y our hands and arm s. You may cut your self
on sh arp-edged metal part s.
• Moisture and i ce on brakes may impair br aking eff icien cy
~ page 237, "General information ". Test the brake s carefully each
time you wash the vehicle .
'£> For the sake of the environment
Select only environmenta lly friend ly c leaning products. Leftover
clean ing products should not disposed of in the household waste .•
Care of exterior
Washing
F requent washing protects the vehicle.
The best protection against environmental influences is frequent
washing a nd waxing. How often this is required depends on :
• How much the vehicle is used
• Where the vehic le is pa rked (garage, in the open under trees,
etc.I
• The seasonal and weather cond itions
• Environmental influences
The longer bird dropp ings, insects, tree resin, road and industrial
grime, tar, soot, road salt and other materials remain on the vehicle
b ody, the more lasting their destructive effects will be. High temper ­
atures caused by exposure to intense sunlight intensify the corro -
sive effect, particularly when humidity is high as wel l. .,

Cast (light) alloy wheels
Cast (light) alloy w heels require special care.
- Wash the wheels with a sponge or hose brush every
o th er week .
- For deep cleaning afte rwards, use only a dedicated
acid ­
free
cast a lloy wheel c leaner.
- Rub a coat of
liquid wa x onto the rims every t hree month.
Be sure to reac h and treat all parts of the rim.
To preserve the decorative appearance of the cast alloy wheels,
some special care is necessary. In add ition to road dirt and salt,
brake dust is also corrosive . If left on for too long, brake dust can
cause p itting.
Use on ly spec ial
acid -free cleaners formu lated for a lloy rims . Safe
products are available at your authorized Audi dealer. Never leave
t he cleaner on the rims longer than specif ied on the label. If not
rinsed off promptly, the acid contained in some cleaners can attack
t he threads on t he wheel bolts.
Never use abrasive or metal po lishing c leaning agents . If the protec ­
t ive coating has been chipped, e.g . by kicked up road dirt, touch it
up as soon as possible.

& WARNING (continued)
crashes and serious personal injuries . Have worn or damaged tires
replaced immediately.
• 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
low speed.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in excess of those standard items
which may be replaced) of automatic transmission, power steering,
power brakes, power windows, power seats, radio, and heater, to
the extent that these items are available as factory-installed equip­

& WARNING
Overloading a vehicle can cause loss of vehicle control , a crash or
other accident, serious personal injury , and even death.
• Carrying more weight than your vehicle was designed to carry
will prevent the vehicle from handling properly and increase the
ri sk of the loss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle with in a safe distance .
• Tires on a vehicle that has been overloaded can fail suddenly ,
in cluding a blowout and sudden deflation , causing loss of control
and a crash .
• Always make sure that the total load being transported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehi cle heavier than the
vehicle's Gross Vehicle Weight Rating. •
Determining correct load limit
Use the example below to calculate the
total weight of the passengers and luggage or other things that you plan to
transport so that you can make sure that
your vehicle will not be overloaded.
Steps for Determining Correct Load Limit
1. Locate the statement "THE COMBINED
WEIGHT OF OCCUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX
LBS "on your vehicle's pla card (tire infla ­
tion pressure label)=> page 291, fig. 229.
2. Determine the combined weight of the driver and passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from
"XXX" kilo­
grams or
"XXX" pounds shown on the
sticker =>
page 291, fig. 229. ~

& WARNING
• Using incorrect or unm atched t ires and / or wheels o r improper
tire and wheel combinations can lead to lo ss of control , collision
and se rious per sonal injury .
• Always use tires , rim s and wheel bolts that meet the specifica ­
t ions of original f actory -installed tire s or other combinations that
have been spe cifically approved by the vehicle manufacturer .
• T ires age even if they are not being used and can fail suddenly ,
especially at high speeds . Tires that are more than 6 years old c an
only be used in an emergen cy and then with spec ial care and at
lower speeds .
• Never mount used tires on your vehi cle if you are not sure of
their "previou s history." Old used tires may have been damaged
e ven though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
• All four wheels must be fitted w ith radial tires of the same type ,
size (rolling circumference ) and the same tread pattern . Driving
with different tires reduces veh icle handling and can lead to a loss
of control.
• If the spare t ire is not the same as the tires that are mounted
on the vehicle -for example with winter tires -only use the spare
tire for a short period of time and drive with e xtra care . Refit the
normal road wheel as soon as safely possible.
• Never drive faster than the ma ximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Overloading tires cause heat build -up , sudden tire failure,
in cluding a blowout and sudden deflation and lo ss of control.
• Tempe rature grades apply to tires that are properly inflated and
not over or under inflated .
• For technical reasons it i s not always po ssible to use wheel s
from other veh icles - in some cases not even wheels from the
same vehicle model .
& WARNING (continued )
• If you install wheel trim discs on the vehicle wheels, make sure
that the air flow to the brakes is not blocked . Reduced airflow to
the brakes can them to overheat , increasing stopping distances
and causing a collision .
• Run flat tires may only be used on vehicles that were equipped
with them at the factory . The vehicle must have a cha ssis designed
for run flat tires and a fa ctory-installed tire pressure monitoring
system* that indicates a loss of tire pressure. Incorrect use of run
flat tires can lead to vehicle damage or acc idents . Check with an
authorized Audi dealer or tire specialist to see if your vehicle can
be equ ipped with run f lat tires . If run flat t ires are used , they must
be installed on all four wheels . Mixing tire types is not permitted.
0 Note
• For technical r eas ons, it is not gen erally possible t o us e the
whee l rims from other veh icles . ihis can ho ld true for whee ls of the
same veh ic le type.
• I f the spare tire is different from the tires that you have mounted
o n yo ur vehicl e (f or example wi nter tires or wide p rofile t ires), then
use the spare tire for a short period of time on ly and drive with extra
care . Rep lace the flat tire wi th the ti re m atchi ng t he o thers on you r
vehic le as soon as possib le.
• I f you should put diff ere nt w heels and tires o n your v ehicle (e. g.
winter wheels and tires), you must be certain that the wheels and
t ires are c ompatib le wi th the tire p ressu re monitoring system* .
Otherwise the system will register a malfunction and a fau lt
mes sage will be displayed . For more info rmation, contact your
author ized Aud i dea ler.
