inside. In this case the child wo
uld be unable to get out of the
vehicle without help. This could have fatal consequences.
•
Never allow children to play in or around the vehicle. Always
close and lock the boot lid and all the doors when you leave the
vehicle.
•
Never let passengers ride in the luggage compartment. All
occupants must be properly restrained by the seat belts at all
times ⇒page 194 .Note
•
Air circulation in the vehicle helps reduce fogging of the
windows. Used air escapes through ventilation slots in the rear of
the vehicle. Make sure that these ventilation slots are not
obstructed.
•
Suitable belts for securing loads to the fastening rings* are
commercially available.
Applies to vehicles: with fastening ringsFastening rings
Unsecured loads are a hazard to all vehicle occupants.There are fastening rings in the luggage compartment
which can be used to secure luggage and other objects
⇒ page 79 .
– Use the fastening rings to secure items safely in the luggage compartment ⇒ in “Loading the luggage
compartment” on page 79.During a collision or an accident, even small and light objects can
possess so much energy that they can cause very severe injuries.
The amount of this “kinetic energy” depends on the speed of the vehicle and the weight of the object. The most significant factor,
however, is the speed of the vehicle.
An example: An object weighing 4.5 kg is lying unsecured in the
vehicle. During a frontal collision at a speed of 50 km/h, this object
generates a force corresponding to 20 times its weight. That means
that the effective weight of the object increases to about 90 kg. You
can imagine the severity of the injuries which might be sustained if
this “projectile” strikes an occupant as it flies through the
passenger compartment.
WARNING
If items of luggage or other obje
cts are secured to the fastening
rings with inappropriate or da maged retaining cords, injuries
could result in the event of sudden braking or a collision.•
To prevent pieces of luggage or other objects from flying
forward, always use appropriate retaining cords which are prop-
erly secured to the fastening rings.
•
Never secure a child seat on the fastening rings.

Head-protection airbags (sideguard)Description of head-protection airbags
The head-protection airbags work together with the side
airbag system to give extra protection in a side impact.The head-protection airbags are loca ted above the doors on the left
and right sides of the vehicle ⇒page 207, fig. 220. The locations of
the airbags are marked with the word “AIRBAG”.
In conjunction with the three-point seat belts and side airbags, the
head-protection airbags give the occupants additional protection
against head and neck injuries in a severe side collision ⇒ in
“Important safety notes on the head-protection airbags” on
page 208 .
Together with other design features (including cross-braces in the
seats and the overall strength of the body structure), the sideguard
system offers an effective further improvement to occupant protec-
tion in side impacts.
How the head-protection airbags work
When fully inflated, the airbags reduce the risk of head or
chest injury in a side collision.In certain types of side collisions the head-protection airbag is trig-
gered together with the side airbag on the impact side of the vehicle
⇒ fig. 221.
When the system is triggered, the airbag fills with a propellant gas
and covers the entire area in front of the side windows, including
the door pillars. In this way the system is able to protect both the
front and the rear occupants on the side of the vehicle where the
impact occurs. The head-protection airbag inflates to soften the
impact if an occupant strikes parts of the interior or objects outside
the vehicle with their head. By reducing the head impact and
restraining uncontrolled movement of the head, the airbag also
reduces the forces acting on the neck. In addition, since it covers the
front door pillar when fully inflat ed, the head-protection airbag also
gives extra protection if the car shou ld collide with an obstacle at an
oblique angle.
The front airbags, side airbags and head-protection airbags may be
triggered together in certain types of accident.
In order to provide the desired extra protection in an accident, the
airbags have to inflate extremely rapidly (within fractions of a

208second). The airbag releases a fine dust when it inflates. This is quite
normal and does not mean there is a fire in the vehicle.Important safety notes on the head-protection airbags
There are a number of safety points concerning the airbag
system which you should remember. This will help to
reduce the risk of injury in an accident.
WARNING
•
It is important to ensure that the area around the openings for
the head-protection airbags remains unobstructed at all times, so
that the airbags can in flate properly if needed.
•
The built-in coat hooks should only be used for lightweight
clothing. Do not leave any heavy or sharp-edged objects in the
pockets. When using the coat hooks, do not hang the clothes on
coat hangers.
•
The space between the passenge rs and the head-protection
airbags must never be occupied by children, other passengers or
pets. Passengers should never lean out or put a hand or arm out of
the window while the vehicle is in motion.
•
Do not move the sun visors out to cover the side windows if
there is anything attached to th em (such as pens or a remote
control for the garage door). These objects could cause injury if the
head-protection airbag is triggered.
•
The sensors for the airbags are lo cated in the front doors. You
must therefore not make any modifications to the doors or door
trim (e.g. retrofitting loudspeakers ), as this could impair the func-
tion of the side airbags. Any dama ge to the front doors could lead
to faults in the system. Repairs or any other work on the front
doors must therefore always be carried out by a qualified work-
shop.
•
Where sun blinds are fitted on th e rear doors, these must not
obstruct or impair th e airbags in any way.
•
If unsuitable accessories are installed near the head-protection
airbag, the protection afforded by the airbag can be seriously
impaired if the system is trigge red. When the head-protection
airbag opens, parts of these acce ssories could be thrown into the
vehicle and injure passengers ⇒page 277 .
•
Any work involving the head-protection airbags, or removal
and installation of the airbag components for other repairs (such
as repairs to the roof liner), mu st always be performed by a quali-
fied workshop. Otherwise the airbag system may fail to work
properly.
Applies to vehicles: with key-operated switch for front passenger's airbagDeactivating the front passenger's airbag via the key-operated switchIf an airbag has been deactivated, it should be reactivated
as soon as possible so that it can continue to give the
required protection.

Intelligent technology
228With the engine switched off
If you listen to the radio or us e the other MMI functions when the
engine is not running, this will discharge the battery.
The MMI display will show this warn ing message before the battery
power drops to a level where the starting ability is impaired.
Please start engine, otherwise system will switch off
in 3 minutes.
This message warns you that the system you are using will be
switched off automatically after 3 minutes. You should therefore
start the engine if you wish to continue using the system.
When the engine is running
Although the alternator generates electrical power, the battery can
still become discharged while the vehicle is being driven. This can
occur when a lot of power is being consumed but only a small
amount supplied, especially if the battery is not fully charged
initially.
To restore the necessary energy balance, the system will then
temporarily shut off the electrical components that are using a lot
of power, or reduce the current they are consuming. Heating
systems in particular use a large am ount of electrical power. If you
notice, for instance, that the seat heating* or the rear window
heater is not working, they may have been temporarily switched off
or regulated to a lower heat output. These systems will be available
again as soon as sufficient electrical power is available.
You may also notice that the engine runs at a slightly faster idling
speed. This is quite normal, and no cause for concern. The increased
idling speed allows the alternator to meet the greater power
requirement and charge the battery at the same time.
Driver message in the instrument cluster displayIf battery power drops to a level at which you may encounter prob-
lems when starting the engine, the following message will appear
in the instrument cluster display:
 Low battery charge: Battery will be charged while driving
This message reminds you that the starting reliability may be
impaired. The message will disappear as soon as you set off and the
battery is charged.
Message comes on and goes out again
If the message appears in the display after the ignition is switched
on or while driving, and goes out again after a period of time, the
battery has been charged up again sufficiently while the vehicle was
being driven.
Message comes on and does not go out
If the message appears in the display after the ignition is switched
on or while driving, and does not go out again, the battery is not
being maintained at the proper power level. Starting reliability may
be impaired. You should have the battery checked by a qualified
workshop as soon as possible.

Save electrical energy
The engine drives the alternator to generate electricity. This means
that fuel consumption rises when more power is required for elec-
trical equipment. Switch off electrical equipment when it is not
needed. Electrical equipment which uses a lot of electricity includes
the blower (at a high se
tting), the rear window heating and the seat
heating*.

Care of vehicle and cleaning
244Care of vehicle and cleaningGeneral notesRegular care helps to maintain the value of the vehicle.Regular and careful care helps to maintain the value of the vehicle.
This may also be one of the requirements for upholding any
warranty claims in the event of corrosion or paint defects.
Audi dealers and specialist retailers carry stocks of suitable car care
products . Please follow the instructions for use on the packaging.
WARNING
•
Cleaning products and other materials used for car care can
damage health if misused.
•
Car care products can contain toxic substances and must
always be kept in a safe plac e out of reach of children.For the sake of the environment
•
When purchasing car care products, try to select ones which are
not harmful to the environment.
•
Surplus cleaning materials should not be disposed of together
with ordinary household waste.
Care of exteriorWa s hi ng t he ve hi c l eThe longer substances like insects, bird droppings, resinous tree
sap, road dirt, industrial deposits, tar, soot or road salt and other
aggressive materials remain on the vehicle, the more damage they do to the paintwork. High temper
atures (for instance in strong
sunlight) further intensify the corrosive effect.
After the period when salt is put on the roads it is important to have
the underside of the vehicle washed thoroughly.
Automatic car washes
Before going through a car wash, be sure to take the usual precau-
tions such as closing the windows and sunroof. If the vehicle has
special accessories such as spoilers or a roof carrier or two-way
radio aerial, etc., it is advisable to consult the car wash operator.
It is best to use a car wash without revolving bristles if possible.
Washing your car with a high-pressure cleaner
When cleaning the vehicle with a high-pressure cleaner, always
follow the operating instructions for the equipment. This applies
particularly to the operating pressure and the spraying distance . Do
not hold the spray nozzle too close to soft materials, such as rubber
hoses or seals.
Do not use a nozzle that sp rays the water out in a direct stream or
one that has a rotating jet for forcing off dirt.
Washing the car by hand
When washing the car by hand, use plenty of water to soften the dirt
first, and rinse off as well as possible.
Then clean the vehicle with a soft sponge, glove or brush , using only
slight pressure. You should start on the roof and work down. Special
car shampoo should only be used for very persistent dirt.
Rinse the sponge or glov e thoroughly and often.
Wheels, sills and similar should be cleaned last. Use a second
sponge for this.

Care of vehicle and cleaning
246Plastic partsPlastic parts will come clean with regular washing. If this is not suffi-
cient, plastic parts should only be treated with a special solvent-free
plastic cleaning agent . Do not use paint cleaners, polishes or wax on
plastic parts.Paint damageMinor damage to the paint, such as scratches or stone chips, should
be touched up without delay before the metal starts to corrode. Suit-
able touch-up brushes or sprays for your car can be obtained from
an Audi dealer.
The number of the original paint finish on the vehicle is given on the
data sticker ⇒page 321 .
If corrosion is already visible it must be thoroughly removed by a
qualified workshop.Windows
Clear vision is an es sential safety factor.The windscreen must not be cleaned with insect remover or wax,
otherwise the windscreen wipers will not function properly
(juddering).
Traces of rubber, oil, grease or silicone can be removed with a
window cleaning solution or a silicone remover . Wax residue can
only be removed with a special cleaner. Your Audi dealer will be able
to provide you with more detailed information.
The windows should also be cleaned on the inside at regular inter-
vals.
Use a separate cloth or chamois to dry the windows. Cloths used for
waxing and polishing contain residues that will cause smears on the
glass.
WARNING
Do not use water-repellent coatings on the windscreen. In bad visi-
bility conditions such as light rain, low sun or when driving at
night these coatings can cause increased dazzle, which is a
serious safety hazard. Such coat ings can also cause the wiper
blades to judder.
Caution
•
Remove snow and ice from windows and mirrors with a plastic
scraper only. To avoid scratches caused by dirt on the glass, the
scraper should only be pushed in one direction and not moved to
and fro.
•
The heating element for the rear window is located on the inner
side of the window. To avoid damaging the heating element, do not
put stickers on the inner side of the window.
•
Never use warm or hot water to remove snow and ice from
windows and mirrors. This could cause the glass to crack!
Rubber seals (weatherstrips)The weatherstrips will remain pliable and last longer if they are
occasionally treated with a suitable care product (for example sili-
cone spray). This will also preve nt premature ageing and leaks. The
doors will be easier to open as well. If they are kept pliable, the door
seals will be less likely to freeze up in the winter.WheelsThe wheels require regular attention to preserve their appearance.
It is important to remove road salt and brake dust by washing the
wheels at regular intervals, otherwise the finish will be impaired.

Technical data
Changing brake fluid
When required, the brake fluid should be changed by a
competent mechanic with the proper equipment.Brake fluid gradually absorbs moisture from the atmosphere. If the
water content in the brake fluid is too high, this may cause corrosion
in the brake system over time. In addition, the boiling point of the
brake fluid will be considerably reduced. This could adversely affect
the braking ability in certain circumstances.
For this reason the brake fluid must be changed periodically.
Your vehicle's Service Schedule will tell you when the brake fluid has
to be changed.
It is advisable to have the brake fluid changed as part of a regular
Inspection Service at your Audi workshop. They are familiar with the
procedure and have the necessary special tools and spare parts as
well as the proper facilities for disposing of the old fluid.
Use only the genuine brake fluid specified by the factory Qualified
workshops know that the brake fluid “DOT 4” is approved by Audi.
The brake fluid must be fresh and unused.
WARNING
•
Brake fluid is poisonous; store it in the sealed original container
in a safe place out of reach of children.
•
Heavy use of the brakes may caus e a vapour lock if the brake
fluid is left in the system for too long. This would seriously affect
the efficiency of the brakes and th e safety of the car – risk of acci-
dent.Caution
Please note that brake fluid will attack the paintwork on contact.
For the sake of the environment
If the fluid has to be drained out of the brake system, use an appro-
priate container to catch the used brake fluid and dispose of it in the
proper manner.BatteryGeneral notes
All work on batteries requires specialist knowledge.The battery is virtually maintenance-free. It is checked as part of the
Inspection Service.
We recommend that you replace a ba ttery once it is older than 5
years.
When an airbag is triggered, the battery will, under certain circum-
stances, be disconnected from the on-board power supply for
safety reasons ⇒ in “General notes on airbag system” on
page 201 .
Disconnecting the battery
If the battery is disconnected, some of the vehicle's functions will
become inoperative (e.g. electric windows). These functions will
require resetting after the battery is reconnected. For this reason,
the battery should only be disconnected from the vehicle's electrical
system when absolutely necessary.
If the vehicle is not used for long periods
If you do not drive your vehicle for a period of several days or weeks,
the power management will gr adually shut off the on-board
systems one by one, or reduce the amount of current they are using.
This limits the amount of power consumed and helps to ensure reli-
able starting even after a long period ⇒page 226 .
