Child safety seats
Infant seats
Babies and infants up to about one year old and 22 lbs or
10 kg need special rearward-facing child restraints that
support the back, neck and head in a crash.

-Push the child safety seat down with your full weight to
get the safety belt really tight so that the seat cannot
move forward or sideways more than one inch (2.5 cm).
Infants up to about one year (22 lbs. or 10 kg) are best protected in
special infant carriers and child safety seats designed for their age
group. Many experts believe that infants and small children should
ride only in special restraints in which the child faces the back of the
vehicle. These infant seats support the baby's back, neck and head
in a crash.

Child Safety
& WARNING
Not using a child safety seat, using the wrong child safety seat or
improperly installing a child restraint increases the risk of serious
personal injury and death in a crash .
• Never install a rear-facing child restraint in the forward-facing
direction. Such restraints are designed for the special needs of
infants and very small children and cannot protect them properly
if the seat is forward-facing.
• Never install a rearward facing child safety seat on the front
passenger seat unless the PASSENGER AIR BAG OFF light comes
on and stays on. If the PASSENGER AIR BAG OFF light does not
come on and stay on the inflating airbag will hit the child safety
seat or infant carrier with great force and will smash the child
safety seat and child against the backrest, door or roof. Have the
airbag system inspected immediately by your Audi dealer.
• Always read and heed all WARNINGS whenever using a child
restrained in a vehicle is being used~

get the safety belt really tight so that the seat cannot move forward or sideways more than one inch (2.5 cm)
~ page 177.
A toddler or child is usually too large for an infant restraint if it is
more than one year old and weighs more than 22 lbs. (1 0 kg).
Toddlers and children who are older than one year up to about 4
years old and weigh more than 22 lbs (10 kg) up to 40 lbs. (18 kg) should be properly restrained in a child safety seat certified for their
size and weight=> fig. 139 .
The airbag on the passenger side makes the front seat a potentially dangerous place for a child to ride. The front seat is not the safest place for a child in a forward -facing child safety seat. It is a very dangerous place for an infant or a
larger child in a rearward-facing
seat.
& WARNING
Not using a child safety seat, using the wrong child safety seat or
improperly installing a child restraint increases the risk of serious
personal injury and death in a collision or other emergency situa­
tion.
• Children on the front seat of any car, even with Advanced
Airbags, can be seriously injured or even killed when an airbag
inflates. A child in a rearward-facing child safety seat installed on
the front passenger seat will be seriously injured and can be killed
if the front airbag inflates -even with an Advanced Airbag System.
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, door or roof.
• Never install a rearward facing child safety seat on the front
passenger seat unless the PASSENGER AIR BAG OFF light comes
on and stays on. If the PASSENGER AIR BAG OFF light does not
come on and stay on have the airbag system inspected immedi­
ately by your Audi dealer.

& WARNING
If exceptional circumstances require the use of a forward-facing
child restraint on the front passenger's seat, the child's safety and
well-being require that the following special precautions be taken:
• Make sure the forward-facing seat has been designed and certi­
fied by its manufacturer for use on a front seat with a passenger
front and side airbag . .,

Child Safety
& WARNING
Using wrong child restraints or improperly installed child
restraints can cause serious personal injury or death in a crash.
• Failure to properly route safety belts over a child's body will
cause severe injuries in a crash. The lap belt portion of the three
point belt must always pass as low as possible across the pelvis,
never over the stomach or abdomen.
• An improperly worn safety belt will not provide the best protec­
tion in a crash and may cause serious personal injury. Always
make sure that children and other vehicle occupants properly
wear available restraint systems. Carefully follow the instructions provided by the manufacturers of child restraints. •
Installing a child safety seat
Securing a child safety seat using a safety
belt
Safety belts for the front passenger can be locked with the
convertible locking retractor to properly secure child
safety seats.
The safety belts emergency locking retractors for the front
passenger's seat safety belt have a convertible locking retractor for
child restraints. The safety belt must be locked so that belt webbing
cannot unreel. The retractor can be activated to lock the safety belt
and prevent the safety belt webbing from loosening up during
normal driving. A child safety seat can only be properly installed
when the safety belt is locked so that the child and child safety seat
will stay in place.
Always remember: Even though your vehicle is equipped with an
Advanced Airbag system, a child should always ride in the seat properly restrained for its age and size. .,_

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

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. •
