Diesel particulate filter
Applies to vehicles: with diesel engine
The diesel particulate fi lter fi lters nearly all of
the soot particles out of the exhaust. The fi lter
cleans itself automatically under normal driving
conditions.
If the filter cannot clean itself (for ex­
ample, because you are only driving short distan­
ces), the filter becomes clogged w ith soot and

_& WARNING
-Do not park you r vehicle over flammable
materials such as grass or leaves because
the high temperature of the diese l particu­
late fi lter could start a fire .
-
-Do not apply an underbody protectant in the
exhaust system area or a fire could start.
Placing your vehicle out
of service
If you would like to take your vehicle out of serv­
ice for a longer time, contact your authorized
Audi dealer or qualified repair facility. They will
adv ise you of important measures, such as corro­
sion protection, maintenance and storage proce­
dures. A lso follow the information about the bat­

Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels .
Fuel economy, environmental impact, and wear
on your engine, brakes and tires largely depend
on three factors :
-your personal driving style
- operating conditions
196
- technical limitations
If you ant icipate what you need to do next and
drive economically, you can easily cut your fuel
consumption by 10-15 percent. This sect ion will
give you some tips on how you can help the envi ­
ronment and your pocketbook.
(D Tips
'
The consumption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehicle
load and speed, road and weather conditions,
trip length, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
.. Avoid unnecessary accelerat ing and braking .
Vehicles use the most fuel when they are acceler­
ating. If you anticipate what is going to happen
next, you will need to brake less and, thus, accel­
erate less. Let the vehicle coast whenever possi­
ble -for example when you see that the next traf­
fic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage.
.. Try and keep well below your car's maximum
speed.
Acce lerating gently reduces fuel consumption,
engine wear, and does not disturb the environ­
ment .
Fuel consumption, exhaust emissions and engine
noise increase disproportionate ly at high speeds.
If you drive at approximately three quarters of
top speed, fuel consumption will be reduced by
one half. Never drive faster than the posted
speed limit and weather conditions permit.

Trailer mode Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation .
If you plan to tow a trailer, please remember that
the additional load will affect durability, econo­
my and performance.
T railer tow ing not only p laces more stress on the
vehicle, it a lso calls for more concentration from
the dr iver.
F or this reason, always follow the operating and
driving instructions provided and use common
sense.
(D Note
If you are going to tow a trailer, you must ac­
tivate the trai ler operation mode
¢ page 199, Operating instructions.
Technical requirements
Tr ailer hitch
Use a weight -carrying hitch conforming to the
gross tra iler weight. The h itch must be suitab le
for your vehicle and tra ile r and must be mo unted
securely on the vehicle's chassis at a
technically
sound
location . Use on ly a trailer hitch with a re­
movable ba ll mou nt. Always che ck wit h the t rail­
e r hitch manufac turer to make s ure that you a re
usi ng the co rrect hitch .
Do not use a bumper hitch .
The hitch must be installed in such a way that it
does not interfere with the impact -absorbing
bumper system . No mod ifica tions should be
made to the vehicle exhaust and brake systems .
Fr om time to time, chec k that all hitch mo un ting
bo lts rem ain securely fastened.
W hen you are not tow ing a trailer,
remove the
tra iler hitch ba ll mount . This prevents the hitch
from ca u sing damage s hou ld your veh icle be
struck from behind

Trailer brakes
If your traile r i s equ ipped with a b raking sys tem,
c h ec k t o be sure that it con forms to a ll regu la ­
tions.
T he tra ile r h ydr aulic bra ke sy stem must not be
directly con nected to the vehicle's hydr aulic
brake sy stem.
Safety chains
Always use safety chains between your vehicle
and the tra iler .
Trailer lights
Trailer lights must meet all regulations. Be sure
to check w it h your Aud i dealer for correct wir ing,
swi tches and relays .
Mirrors
If you are unab le to see the traffic behind you us­
ing the regular outside mirrors, then you
must in­
stall extended mirrors . It is important that you
always have clear vision to the rear .
A WARNING
--
After remov ing the tra ile r hi tch, do not sto re
i t in yo ur vehicle. In case of sudde n brak ing,
t he hitch could fly fo rwa rd and injure you or
your passengers.
Operating instructions
Maximum trailer weight
A traile r for yo ur vehicle is lim ited to a typical
cla ss 1 or class 2 trailer.
Trailer load distribut ion
Be sure the load in the tra iler is held secure ly in
place to p reve nt it from shifting forward, back­
ward o r sideways.
Ne ver allow a passenger to ride in a trailer¢.&.
in Driving instructions on page 201 .
Engine cooling system
Towing a tra ile r makes the engine wor k harder. It
is important that the cooling system's perform­
ance is up to the additional load. Make sure that
the cool ing system has enoug h fluid . .,..

Tire pr essure
When tow ing a tra iler, inflate the tires of you r
veh icle to the cold tire pressure listed under "Fu ll
load" on the label located on the driver's side B ­
pillar (visib le when the door is open) . Inflate
trai ler tires to trailer and tire manufacturers'
specifications.
Light s
Check to make sure both vehicle and trailer lights
are working proper ly.
Safet y chains
Be sure t railer safety chains are properly connect­
ed from the trailer to the h itch on the veh icle.
L eave enough slack in the chains to permit turn­
ing corners . When yo u install safety chains, make
sure they wi ll not drag on the road when you are
driving.
The chains shou ld cross under the trailer tongue
to prevent it from dropping in case of separation
from the hitch .

· Driving instructions
Driving with a trailer always requires extra care
and consideration .
To obtain the best possible hand ling of veh icle
and trailer, please note the following:
.,. Do not tow a loaded trailer when your car itself
is not loaded .
.,. Be especially careful when passing other
vehicles .
.,. Observe speed limits .
.,. Do not dr ive at the maximum permissible
speed.
.,. Always app ly brakes ea rly.
.,. Monitor the temperat ure gauge.
Weight distribution
Towing a loaded trai ler with an empty car results
i n a h ighly unstab le distribution of weight . If this
cannot be avoided, drive at very low speeds only
to avoid the risk of losing steer ing contro l.
A "balanced" rig is easier to operate and control.
This means that the tow vehicle shou ld be loaded
to the extent possible and permissib le, wh ile
k eeping the trailer as l ight as poss ible under the
c ircu mstances . Wheneve r possib le, transfer
some ca rgo to the luggage compartment of the
tow vehicle while observing tongue load require­
ments and vehicle loading considerations.
Speed
The higher the speed, the mo re diff icu lt i t be ­
comes fo r the driver to con trol the r ig . Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or wind
cond itions are unfavorab le -particularly when
go ing downh ill.
Reduce vehicle speed
i mmed iatel y if the trailer
shows the slightest sign of swaying.
Do not tr y
to stop the swaying by accelerating.
Observe speed limits . In some areas, speeds for
vehicles towing trailers are lower than for regular
vehicles .
Always apply bra kes early. Whe n driving down -
hill, shift into a lower gear to use the engine .,..

braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fail.
Air suspension*
When driving with a tra ile r, activate the trailer
mode of the air suspension. Switch the air sus ­
pension trailer mode on when you are towing a
trailer. This will limit the regulation by the air
suspension while driving. Select in the MMI :
ICARI function button > (Car)* systems control
button>
Vehicle settings> Air susp.: towing>
On.
Coolant temperature
The coolant temperature gauge¢ page 10 must
be observed carefully . The coolant temperature
can increase if you drive on long inclines in a low
gear at high engine speeds. Reduce your speed immediately if the LEDs in the top part of the dis­
play turn on .
For more information about ind icator lights, re­
fer to. ¢
page 15.
A WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent. Never let anyone ride in your car who is
not p roperly wearing the restraints p rovided
by Audi.
Trailer mode notes
Important to know -
Your vehicle handles differently when towing a
trailer because of the additional weight and dif­
ferent weight distribution. Safety, performance
and
economy will greatly depend on how careful­
ly you load your trailer and operate your rig .
Before you actually tow your trailer, practice
turning, stopping and backing up in an area away
from traff ic. Keep practicing until you have be­
come comp letely fami liar with the way your vehi­
cle-trailer comb inat ion behaves and responds.
Backing up is difficult and requires practice.
Backing up with a trailer generally requires steer-
Trailer mode
ing 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 trailer, you
will need a larger than normal turning radius .
When passing, remember that you cannot accel­
erate as fast as you normally wo uld because of
the added load . Make sure you have enough room
to pass. After passing, allow p lenty of room for
your trailer before changing lanes again .
Avo id jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in peri­
od of your veh icle.
-If you tow a trailer, your Audi may require
more frequent maintenance due to the ex­
tra load ¢

Parking on a slope
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 place chocks under both the ve­
hicle and the trailer wheels.
"W ith chocks in place, slowly release the brakes
until the wheel chocks absorb the load.
" Turn the whee ls towards the curb.
" App ly the parking brake.
" Select the P selector lever position.
When restarting after parking:
"App ly the foot brake.
" Start the engine .
"S elect the D/S se lector lever position.
" Release the parking brake and slowly pull out
and away from the wheel chocks.
" Stop and have someone retrieve the wheel
chocks.

Care and cleaning
-To reduce the risk of cuts, protect yourself
from sharp metal components when was h­
ing the underbody or the inside of the wheel
housings .
- After washing the vehicle, the braking effect
may be delayed due to mo isture on the
brake rotors or ice in the winter . The brakes
must be d ried first w ith a few careful b rake
applications.
(D Note
- If you wash the vehicle in an automatic car
wash, you must fold the exte rior m irrors in
to reduce the risk of damage to the mirrors.
Power folding exte rior m irrors* must on ly
be fo lded in and out us ing the powe r folding
f u nct ion.
- To p revent paint damage , do not wash the
vehicle in di rect sunlight.
- To reduce the risk of damage to the surface,
do not use insec t remov ing sponges, kit chen
sponges or similar items. - Matte finish painted vehicle components:
-To reduce the r isk of damage to the sur-
face, do not use polis hing agents or hard
wax.
- Never use protective wax. It can destroy
the matte finish effect .
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint. The paint could be damaged
when the stickers or magnets are re­
moved.
@ For the sake of the environment
Only wash t he ve hicle in facilities spec ially de­
signed for that pu rpose . This will reduce the
r isk of dirty wate r contaminated with o il from
ente ring the sewe r system.

-N ,::
~
Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS
¢ A in Working in the engine compartment on
page 216.
.,. Read the brake fluid level from the brake fluid
reservoir
¢fig. 190, ¢page 218, fig. 186. The
brake fluid level must be between the "MIN "
and "MAX" markings.
The location of the brake fluid reservoir can be
seen in the engine compartment illustration
¢page 218.
The fluid level may drop slightly after some time
due to the automatic adjustment of the brake
pads. This is not cause for alarm.
If the brake fluid level falls
considerably below
the "MIN" mark, the brake warning/indicator
light
1111 (U.S. models) ;II (Canadian models)
will come on¢
page 14. Do not continue to oper­
ate the vehicle. The complete brake system
should be thoroughly checked by an authorized
Audi dealer or other qualified facility and the
cause corrected. If the brake fluid level is too
low, the brake warning/indicator light will illumi ­
nate. Contact an authorized Audi dealer
immedi­
ately.
Checking and Filling
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs moisture from the air. If the
water content in the brake fluid is too high, cor­
rosion in the brake system may result after ape ­
riod of time . The boiling point of the brake fluid
will also decrease considerably and decrease
braking performance.
Therefore, the brake fluid must be changed
every
two years . Always use new brake fluid which con­
forms to Federal Motor Vehicle Standard "FMVSS
116 DOT 4" .
The brake fluid reservoir can be difficult to reach,
therefore, we recommend that you have the
brake fluid changed by your authorized
Audi
dealer. Your dealer has the correct tools, the
right brake fluid and the know-how to do this for
you.
A WARNING
- Brake fluid is poisonous. It must be stored
only in the closed original container out of
the reach of children!
- Brake failure can result from old or inappro­
priate brake fluid . Observe these precau­
tions:
- Use only brake fluid that meets SAE speci­
fication
J 1703 and conforms to Federal
Motor Vehicle Standard 116. Always check
with your authorized Audi dealer to make
sure you are using the correct brake fluid.
The correct type of brake fluid is also indi­
cated on the brake fluid reservoir.
- The brake fluid must be new. Heavy use of
the brakes can cause a vapor lock if the
brake fluid is left in the system too long.
This can seriously affect the efficiency of
the brakes as well as your safety. This
could result in an accident.
(D Note
Brake fluid will damage the paint of your vehi-
cle.
