soiling, etc.I, you will need to be somewhat careful with these
leathers, and a certain type of care is required. For example, dark
clothing materials can discolor leather seats (especially if such
clothing is damp and was not dyed correctly). Dust and dirt particles
in pores, folds, and seams can have an abrasive effect and can
damage the leather surface as well as weaken seams.
The leather shou ld be c leaned regularly as needed. After having
been used for a relatively long time, your leather seats will acquire
a rich aged finish . This is a characteristic of natural leather and a
sign of true quality.
In order to maintain the value of this natural product over the life of
your vehic le , you should fo llow the recommendations below:
0 Note
• To keep your leather from bleaching out, do not allow it to be
exposed to bright sunlight for long periods of time. If you have to
leave the vehicle parked outside for long periods, cover the leather
to protect it from direct exposure to sunlight.
• Sharp objects on c lothing, such as zippers, rivets or sharp pieces
on belts can leave permanent scratches or scrape marks on the
surface of the leather.
[ i ] Tips
• After each time you clean the leather and at regu lar intervals, use
a leather preservative creme that contains UV -blockers and that
works into the leather. This creme wil l nourish and moisturize the
leather, helping it to breathe and stay supple . It also helps to build
up a protective coating on the surface .
• Clean the leather every 2 -3 months, and clean any areas that get
soiled.
• Remove fresh marks made by ballpoint pens, ink, lipstick, shoe
polish, etc . as soon as possible.
• Preserve the color of the leather as needed by using a special
colored leather care creme to touch up areas of uneven color .•

Cleaning and caring for leather upholstery
and trim
Natural leather requires special care and attention.
Normal cleaning
-Clean soiled areas with a slightly moistened cotton or
woolen cloth.
More stubborn dirt
-More stubborn dirt can be removed using a cloth satu­
rated with a mild soap solution (2 tablespoons mild
liquid soap).
-Never allow the soap solution to saturate the leather, and
make certain that no water soaks into the seams.
Wipe off the soap solution with a soft, dry cloth .
Cleaning spots
-Remove fresh water-based spots (such as coffee, tea,
juices, blood) with an absorbent cloth or paper towel.
-Remove fresh grease or oil-based spots (such as butter,
mayonnaise, chocolate) with an absorbent cloth or paper
towel, or use the cleaner from the leather care kit if the
spot has not yet penetrated into the surface of the
leather.
-Use an oil/grease dissolving spray, if oil/grease spots
have dried on.
-Remove specific kinds of spots (ballpoint pen, felt
marker, fingernail polish, water-based paint, shoe polish,
etc.) with a spot remover specifically formulated for
leather. _.,

f lu id rese rvoi r
Before you check a nything in the e ngine compartment,
alway s re ad and he ed all WARNINGS ~ & in "Working in
the engi ne com partment" on
page 273.
- Pull the rubber st rip @ up partially and lift the cover @
slightly~ fig. 212 .
- Read the brake fluid level from the brake fluid reservoi r
@. The brake fluid level must be between the "MIN" and
"MAX" markings.
The brake fluid reservoir is located at the rear partition of the engine
compartment on the le ft side
~ page 275.
The fluid level may drop slightly after some time due to the auto ­
matic adjustment of the brake pads. This is not cause for alarm.
If the brake fluid level fal ls
considerably below the "MIN" mark, the
brake warning/indicator light (U .S . models :
BRAKE, Canadian models:
0) will come on=> page 23 and~ page 31 . Do not continue to
opera te the vehicle. The complete brake system should be thor ­
oughly checked by an authorized Audi dealer or qua lified workshop
and the cause corrected. If the brake fluid level is too low, the brake
warning/indicator light will illuminate . Contact an authorized Audi
dea ler
immedi atel y.•
Changing brake fluid
H ave the brake fluid changed by an experienced techni ­
cian.
Brake fluid absorbs mo isture from the air . If the water content in the
brake fluid is too high, corrosion in the brake system may result
after a period of time. The bo iling point of the brake fluid wil l a lso
decrease considerably and decrease braking performance.
Therefore, the brake fluid must be changed
e ver y tw o year s. Always
use new brake fluid which conforms to Federal Motor Vehic le Stan­
dard "FMVSS 116 DOT
4".
The brake fluid rese rvo ir can be difficult to reach, therefore, we
recommend that you have the brake fluid changed by your autho­
rized
Audi dealer . Your dealer has the correct tools, the right brake
fl uid and the know-how to do this for you.
& WARNING

J 1703 and
