Trailer mode notes
Important to know
Your vehicle handles different ly when tow ing a
trailer because of the additional weight and d if­
ferent weight distr ibution. Safety, perfo rmance
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 traffic. Keep practicing until you have be­
come completely familiar with the way your vehi­
cle-trailer combination behaves and responds.
Backing up is difficult and requires pract ice.
Backing up with a trailer generally requires steer­
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 pass ing, remember that you cannot accel­
erate as fast as you normally would because of
the added load. Make sure you have enough room
to pass. After passing, allow plenty of room for
your trai ler before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in peri­
od of your vehicle.
- 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.
0 ~ .. Have someone place chocks under both the ve-
~ hicle and the trailer wheels. Lil ,...., v:, ,....,
Trailer mode
.. With chocks in place, slowly release the brakes
until the wheel chocks absorb the load.
.. Turn the wheels towards the curb .
.. Apply the parking brake.
.. Place an automatic transmission* in P, respec­
tively a manual transmission in first or reverse
gear .
When restarting after parking:
.. App ly the foot brake.
.. Start the engine .
.. Move the selector lever to D/S, respectively a
manual transmission in first gear .
.. Release the parking brake and slowly pull out
and away from the wheel chocks.
.. Stop and have someone retrieve the wheel
chocks.
(D Tips
If you move the selector leve r of the automat­
ic transmission* to P before applying the
parking brake and before blocking the wheels,
you may have to use more force later to move
the lever out of the P position.

dents.
- To reduce the risk of cuts, protect yourself
from sharp metal components when wash­
ing the underbody or the inside of the wheel
housings .
- After washing the vehicle, the brak ing effect
may be delayed due to mo isture on the
brake rotors or ice in the w inter . The brakes
must be dried first w ith a few careful brake
applica tions .
- If you wash the vehicle in an automatic car
wash, yo u m ust fold the exterior m irrors i n
to reduce the risk of damage to the mirrors.
Power folding exte rior m irrors* must on ly
be fo lded in a nd out using the power folding
funct ion.
- To p revent paint damage, do not wash the
vehicle i n direct sunlight.
- To reduce the risk of damage to the surface,
do no t use insect remov ing s ponges, kit chen
spo nge s or similar i tems .
- M atte fi nish pa inted vehicle components :
- To red uce the risk of damage to the s ur-
face, do not use polishing agents or hard
wax.
- Never use protect ive wax .
It can dest roy
the matte finish effect.
- Do not place any stickers o r magnet ic
signs on vehicle pa rts pa inted with matte
fin is h pa int. The paint could be damaged
when the stickers or magnets are re­ moved .
@ For the sake of the environment
Only wash the vehicle in facilities specially de­
signed for that purpose. This will reduce the r isk of dirty water contaminated with oil from
entering the sewer system .

Check ing and F illing
The brake fluid rese rvoir is located at the rear
partition of the engine compartment on the l eft
side
c!,> pag e 193 .
The fl uid level may drop slightly after some time
due to the automatic adjustment of the brake
pads . This is not cause for alarm.
If th e b rake fl uid level fa lls considerably be low
the "M IN" mark, the b rake warning/ind icator
lig ht ( U.S. mode ls :
1111 , Canadian models:. )
will come on
c!,> page 15 . Do not contin ue to oper ­
ate the vehicle . T he comp lete brake system
should be thoroughly checked by an authori zed
Aud i dealer or qualified workshop and the cause
corrected . If the brake flu id level is too low, the
b rake warning/indicator light will i llum inate.
Contact a n author ized Audi dealer
immediately .
{D) Tips
The brake fluid reservoir is located under­
neath the cover .
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs mo isture from the air. If the
water content in the b rake fluid is too high, cor­
rosion in the brake system may resu lt afte r ape ­
riod of t ime. The boiling poi nt of the brake flu id
will also decrease cons iderably and decrease
b raking perfo rman ce.
Therefore, the brake fluid must be changed
every
two year s.
Always use new brake fluid wh ic h con­
forms to Fede ral Motor Veh icle Standard "FMVSS
1 16 DO T 4".
The brake fluid reservoir can be diff icult to reach,
therefore, we recommend that yo u have the
brake fl uid changed by yo ur autho rized
Audi
dealer .
Your dealer has t he corre ct tools, t he
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 orig inal container out of
the reach of chi ldren!
200
- Bra ke fa ilure ca n result from old or inapp ro­
priate brake fluid . Observe these precau­
tions:
- Use only brake fluid t hat meets SA E speci­
fi ca ti on
J 170 3 and con forms to Federa l
Motor Ve hicle Standard 116 . Always check
wi th yo ur autho rized Audi dea le r to make
s ur e yo u are using the correct brake fluid .
The correct type of brake flu id is also ind i­
cated on the b rake fluid reservo ir .
- The brake fluid m ust be new . Heavy use of
the brakes can cause a vapo r lock if the
brake fluid is left in the system too long .
This can se riously affect the efficiency of
the b rakes as well as your safety . This
could resu lt in an accident .
(D Note
Brake fluid will damage the paint of your veh i­
cle.
@ For the sake of the environment
Because of the problem o f proper d isposa l o f
brake fluid as well as the spec ial too ls re­
q ui red a nd the necessary expertise, we rec­
omme nd that you have the bra ke f luid
changed by yo ur autho rized Aud i dea le r.
Battery
, General information
U nder normal operating condit ions, the battery
i n your Audi does not need any maintenance.
With
high outside temperatures or long daily
drives we recommend that you have the elect ro ­
lyte level c hecked by an au thorized Aud i dealer o r
qualified workshop. The electro lyte level shou ld
a lso be che cked each time the battery is c ha rged
c:!,> page 202.
Have the batte ry chec ked when you take yo ur ve­
hicle in for service. You are we ll adv ised to re­
pla ce a battery tha t is older than 5 yea rs.
With certain types of airbag deployment, t he
batte ry is d iscon nected from the ve hicle electri­
ca l system for safety reasons

(b) Accessory weight
(c) Vehicle capacity weight, and
(d) Production options we ight
Ma ximum (permissible)
inflation pressure
means the maximum cold infla­
tion pressure to which a t ire may
be inflated. Also called "maxi ­
mum inflation pressure."
Normal occupant weight
means 150 lbs. (68 kilograms)
times the number of occupants
seated in the veh icle up to the to­
tal seating capacity of your vehi­ c le.
Occupant distribution
means distribution of occupants
in a vehicle.
Outer diameter
means the overall diameter of an
inflated new tire.
Overall width
means the linear distance be­
tween the exteriors of the side­
walls of an inflated tire, including elevations due to labeling, deco ­
rations, or protective bands or
ribs .
Wheels
Ply
means a layer of rubber-coated
parallel cords .
Production options weight
means the combined weight of
those installed regular production
options weighing over 5 lbs. (2.3 kg) in excess of those standard
items which they replace, not pre­
viously considered in curb weight
or accessory weight, including heavy duty brakes , ride levelers,
roof rack, heavy duty battery, and
special trim .
Radial ply tire
means a pneumatic tire in which
the ply cords that extend to the beads are laid at substantially 90
degrees to the centerline of the
tread.

Wheels
plus maximum load . The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seat ing capaci­
ty") with an assumed weight of
150 lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any luggage in the vehicle. If you tow
a trailer , the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load .
The
Gross Axle Weight Rating
( " GAWR") is the maximum load
that can be applied at each of the
vehicle 's two axles.
The fact that there is an upper limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited . The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as
luggage.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating
218
are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar
~ page 215,
fig . 169 .
& WARNING ~ -
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to
carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance .
-Tires on a vehicle that has been overloaded can fail sud ­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash .
-Always make sure that the to­ tal load being transported -
including the weight of a trail­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle 's
Gross Vehicle Weight Rating.
