Automatic car wash
The vehicle can be washed in almost any modern auto­
matic car wash.
The vehicle paint is so durable that the vehicle can normally be
washed without problems in an automatic car wash . However , the
effect on the paint depends to a large extent on the design of the
facility, the filtering of the wash water, the type of wash and care
material, etc. If the paint has a dull appearance after going through
the car wash or is scratched, bring this to the attention of the oper­
ator immediately . If necessary, use a different car wash .
The power top does not require specia l precautions before passing
through a car wash.
However, the car must not be treated with hot
wax after the wash cycle!
The wax could adversely affect the power
top and even damage the fabric over a period of time.
The power top do es not have to be washed every time you use a car
wash . The power top can be spared if the car wash facility is
equipped with manually adjustable roof brushes or rollers.
Before going through a car wash, be sure to take the usua l precau ­
tions such as closing the windows. Remove antenna if applicable . If
you have installed additional accessories on the vehicle -such as
spoilers, etc. -it is best to ask the car wash operator if these should
be removed.
& WARNING
Always read and heed all WARNINGS and the information
=> page 200. •
Washing the vehicle by hand
A lot of water is needed when washing a vehicle by hand.
-Before you start washing, make sure you have read and
understood the WARNINGS ::}
& in "General informa­
tion" on
page 200.
-First soak all dried dirt until it is soft, then rinse it off.
- As you clean your vehicle, start with the roof and work
your way down to the bottom, using a sponge, a sponge
glove or a clean brush.
- Rinse the sponge or the sponge glove often, flushing it
clean each time.
- Use special car shampoo only for very persistent dirt .
- Rinse the car thoroughly with water.
- Use a chamois leather to gently wipe the exterior dry.
Use a separate sponge for cleaning the wheels, door si lls and other
regions exposed to road dirt. In this way, you will not scratch the
paint with coarse particles imbedded in the sponge the next time
you wash the car . .,,

At the time of printing, engine oils available in the U.S . and Canada
t hat meet the exacting specifications of Audi oil standard VW 502 00
are synthetic engine oils . This does not mean, however, that every
synthetic engine oil will meet Audi oil standard VW 502 00. So
always be sure that you use an approved oil.
To help prevent the formation of harmful deposits use only oil with
the follow ing spec ifica tions pr inted on the oil container:
Au di oi l stan dar d VW 502 00
Oil container labels may carry the specification singly or in combi­
nation with other designations and o il quality standards.
V isc osit y
Engine oils are graded according to their viscosity . The proper
viscosity grade oi l for your engine depends on climactic or seasona l
conditions where you drive . You can use oil with a v iscosity grade of
SAE 5W40 across all temperature ranges for normal driving condi ­
tions.
However, if eng ine oil viscosity grade SAE 5W40 is not available, you
can a lso use viscosity grade SAE 5W-30 or SAE 0W-40 as long as it
meets Audi oil qua lity standard VW 502 00 specifications .
Because engine oil that meets the Audi oil standard may not be
available everywhere when you need it, we s trong ly recommend
that you a lways carry with you an extra quart ( liter) of oil that
expressly conforms to the VW 502 00 specification, in case you have
to top off the o il while on the road.
On ly if the level of the oil is at or below the minimum mark on the
oi l dipstick -and no oil that express ly conforms to Audi oi l standa rd
VW 502 00 specifications is available -may you top off with a high
qual ity engine oi l, preferably synthetic -based, t hat meets ACEA A3,
ACEA A5 or ACEA 85, API SL or ILSAC GF -3 specifications, but even
then, only in viscosity grades SAE 5W -40, SAE 5W -30, or SAE 0W -40.
However, dur ing the entire time between oi l change intervals, never
top off w ith more than a total of 0.5 qt/liter engine oil that does not
confo rm to Audi oil specificat ion VW 502 00. For more information about engine oil that has been approved for
your vehicle, p lease con tac t ei the r your authorized Audi dea ler or
Aud i Customer Relations at 1 (800) 822-2834 or visit our web site at
www .audiusa .com or www .audicanada.ca. Here you will a lso find a
current list of oils (manufacturers, brand names etc.l that conform
to Audi oi l standard VW 502 00 .
Changing the engine oil
The engine oil and oil filter must be changed according to the
mi leage (k ilometers) and time intervals specified in your vehic le's
Maintenance
& Warranty booklet. Do not exceed these intervals -
harmfu l deposits from old engine oil can reduce engine perfor­
mance and can lead to expens ive eng ine repairs.
Changing the oil at the recommended interva ls is so very important
because the lub ricating properties of oi l decrease gradua lly during
normal vehicle use. If you are not sure when you have your oil
changed, ask you r authorized Audi Service Advisor .
Under some circumstances the engine oil should even be changed
more frequently. Change oi l mo re often if you drive mostly short
distances, operate the vehicle in dusty areas o r mostly under stop­
and -go traffic conditions, or when you use your vehicle where
temperatures stay below freezing point for long per iods.
Detergent additives in the oil will make fresh oi l look dark after the
engine has been running for a sho rt time. Th is is normal and is not
a reason to change the oil more often than recommended.
D amag e or malfun ctions due to la ck of mai nten ance
It is essential that you change your oi l at the recommended interva ls
using on ly engine oil that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle War ranty does not cover
damage or malfunctions due to failure to fol low recommended
maintenance and use requirements as set forth in the Audi Owner's
Manual and Maintenance
& Warranty booklet . Your dealer wi ll have
to deny warranty coverage unless you present to the dealer proof in
the form of Service or Repair Orders that all scheduled maintenance
was performed in a timely manner. •
