Audi side assist
150
Switching on
– Press the button ⇒page 149, fig. 165. The red indicator
lamp in the button will light up.
Switching off
– Press the button again. The indicator lamp in the button will go out.The system is designed to provide assistance on motorways and
other out-of-town roads, so it only operates at speeds above about
60 km/h.
WARNING
•
Please note that the sensors ar e not always able to detect all
vehicles which may represent a po tential hazard (accident risk).
•
Please note that the side assist is not able to give adequate
warning of vehicles approaching very fast from behind, or vehicles
that you are overtaking rapidly.
•
The radar sensor's "field of vision" can be impaired by rain,
snow or a lot of water on the road. This results in vehicles not
being reliably recognised or, in some circumstances, not being
detected at all by the side assist. Al ways give your full attention to
the position of your vehicle on the road and other nearby traffic.
•
The side assist only gives a warning of approaching vehicles
and vehicles in the blind spots when road speed is above 60 km/h.
•
Please note that the side assist does not operate in tight bends
(with a radius of less than 200 metres).
•
The side assist feature is not a su bstitute for the full concentra-
tion of the driver. The driver is al ways responsible for the safety of
lane changes and other manoeuvres. Always give your full atten-
tion to the position of your vehicle on the road and other nearby
traffic.
Caution
•
To avoid impairing the function of the side assist, do not attach
any objects (e.g. stickers or bicycle carriers) in such a way that they
might interfere with the radar sensors in the rear bumper.
•
Make sure that the warning lamps on the exterior mirrors are not
obscured by stickers or other objects.Note
•
To ensure that the side assist function works properly, do not
allow snow and ice to accumulate on the rear bumper near the radar
sensors. Please observe the additional notes on ⇒page 157 .
•
The side assist function will be switched off automatically when
the electrical connector for the trailer socket is plugged in on vehi-
cles with a factory-fitted towing bracket.
•
The side assist should be switched off manually when towing a
trailer if the vehicle is equipped with a towing bracket which was not
factory-fitted.
•
The side assist system will switch off automatically if it detects
an obstruction that impairs the function of the radar sensors.
•
The warning lamps on the exterior mirrors may not be properly
visible if tinted foil is affixed to the side windows on the driver's or
passenger's side.

WARNING
•
When applying the brakes to clean off deposits on the pads and
discs, select a clear, dry road. Be sure not to inconvenience or
endanger other road users; do not risk an accident.
•
Never let the car coast with the engine switched off (this can
cause accidents).Caution
•
Never let the brakes “drag” by leaving your foot on the pedal
when you do not really intend to brake. This overheats the brakes,
resulting in longer stopping distances and greater wear.
•
Before driving down a long, steep gradient, it is advisable to
reduce speed and move the selector lever to a lower gear. In this
way you will make use of the engine braking effect and relieve the
load on the brakes. If you still have to use the brakes, it is better to
brake firmly at intervals than to apply the brakes continuously.Note
•
If the brake servo is out of action due to a malfunction, or if the
car has to be towed, you will have to press the brake pedal consid-
erably harder to make up for the lack of servo assistance.
•
If you wish to equip the car with accessories such as a front
spoiler or wheel covers, it is impo rtant that the flow of air to the
front wheels is not obstructed, otherwise the brakes can overheat.
Power steering (servotronic)The power steering assists th e driver when turning the
steering wheel (with the engine running).The power steering assists the driver by reducing the force needed
to turn the steering wheel. The degree of power assistance is
adapted electronically , depending on the speed. If a fault should occur in the
servotronic system the power steering
will still operate. The degree of power assistance will, however, no
longer adapt to different speeds. If the electronic regulating system
is not working properly, this is most noticeable when turning the
steering wheel at low speeds (for instance when parking) – more
effort will be required than usual. The fault should be corrected by
a qualified workshop as soon as possible.
The power steering does not function when the engine is switched
off. In this case the steering wheel is very hard to turn.
If the steering is held at its turning limit when the car is stationary,
this will place an excessive load on the power steering system. In
this case, the power steering system will make noises. It will also
reduce the idling speed of the engine.
Caution
Do not keep the steering in the full-lock position for longer than
15 seconds when the engine is running – this could cause damage
to the power steering system.
Note
•
If the power steering should fail at any time or the engine is
switched off (for instance when being towed), the car can still be
steered. However, more effort will be required to turn the steering
wheel.
•
If the system is leaking or malfunctioning, please take the car to
a qualified workshop as soon as possible.
•
The power steering requires a special hydraulic fluid. The fluid
reservoir is located at the front of the engine compartment on the
left ⇒page 256 . The correct fluid level in the reservoir is important
for the power steering to function properly. The hydraulic fluid level
is checked at the Inspection Service.

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.

Technical data
WARNING
•
Do not wash the vehicle with the ignition switched on – risk of
accident.
•
Do not clean the underside of th e car or inside the wheel arches
without protecting your hands and arms. You may cut yourself on
sharp metal parts.
•
Take care when washing the car during the winter: moisture
and ice on the brakes may affect braking efficiency – this could
cause an accident.Caution
•
Do not wash the vehicle in direct sunlight – otherwise the paint
can be damaged.
•
Do not use insect sponges or ab rasive household sponges, etc.
– they can damage the surfaces.
•
The headlights should only be washed with water – do not wipe
them with a dry cloth or sponge . It is best to use soapy water.
•
Never wash tyres with a jet that sprays the water out in a direct
stream. This could damage the tyres – even if the spray is kept at a
distance and only used for a very short time.For the sake of the environment
The car should only be washed in special wash bays. This prevents
oily water from getting into the pu blic drains. In some districts,
washing vehicles anywhere else may be prohibited.Waxing and polishingWaxing
Waxing protects the paintwork. It is time to apply a good coat of wax
when water no longer forms droplets and rolls off the clean paint-
work. Even if a
wax solution is used regularly in the car wash, it is advis-
able to protect the paint with a coat of wax at least twice a year.
In the summer, you will find it is much easier to remove dead insects
(which accumulate on the bumper an d the front of the bonnet) if the
car has been waxed recently.
Polishing
Polishing is only necessary if the paint has lost its shine, and the
gloss cannot be brought back by putting on wax.
The car must be waxed after polishing if the polish used does not
contain wax compounds to seal the paint.
Caution
Matt painted and plastic parts mu st not be treated with wax or
polish.Ornamental trim and mouldingsThe metal brightwork on the body is made of aluminium rather than
chrome (for environmental reasons).
Dirt or marks on the trim mouldings should be removed with an
acid-free cleaning agent (do not use a chrome cleaner). Body polish
is also unsuitable for use on trim mouldings. The intensive cleaning
fluids often used before the car goes into a car wash may contain
alkaline substances, which can cause dull or milky patches when
they dry out.
Audi dealers carry stocks of cleaning products which have been
tested for use on your vehicle and are not harmful to the
environment.

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.

cloth or sponge and then dab th e stain with an absorbent cloth.
Treat chocolate or make-up stains with a washing paste and then
rinse off with water (using a damp sponge).
A spirit-based cleaner can be used to remove grease, oil, lipstick or
ball point pen. Then dab the dissolved grease or colour particles off
with an absorbent cloth or similar. You may also have to treat the
stain once more using washing paste and water.
If the covers or textile trim panels are badly soiled we recommend
that you have them cleaned by a professional cleaning company.
Note
Please make sure you close any velcro fasteners on your clothing, as
these could otherwise damage the upholstery.Applies to vehicles: with leather upholsteryNatural leather
Audi does everything possible to preserve the special
qualities of leather as a natural product.General notes
We have a wide selection of leathers. The main type used is nappa
in various forms, that is leather with a smooth surface in a selection
of colours.
The amount of dye used determines the appearance and properties
of leather. If the leather is left in a more natural state, it retains its
typical natural appearance and is pleasant and comfortable for the
seat occupants. Fine veins, healed scars, insect bites, wrinkles and
a subtle variation in shading remain visible; these are the character-
istic features of genuine natural leather.
Natural napped leather does not ha ve a protective surface coating
of dye. It is therefore somewhat more prone to damage. You should bear this in mind if children or pets often travel in the car, or if there
are other factors that
could lead to damage.
Types of leather with a coloured surface coating are likely to be
more resistant to damage. This has a great advantage for day-to-day
use. However, this means that the typical natural characteristics of
the surface are less apparent, though this does not affect quality.
Cleaning and care
Because of the natural properties of the specially selected hides
employed, the finished leather has a certain sensitivity to grease
and dirt, etc. so a degree of care is required in everyday use and
when looking after the leather. Dark clothing (especially if damp or
incorrectly dyed) may stain leather upholstery. Dust and grit in the
pores and seams can have an abrasive effect and damage the
surface of the leather. Therefore leather should be cleaned at
regular intervals, depending on the actual amount of use. When
they have been in use for a certain time, your car seats will acquire
a typical and distinctive patina. This is characteristic for real leather
upholstery, and is a sign of genuine quality.
To maintain the value of natural leather you should note the
following points:
Caution
•
Avoid exposing leather to direct sunlight for long periods, other-
wise it may tend to lose some of its colour. If the car is left for a
prolonged period in the bright sun, it is best to cover the leather.
•
Sharp-edged objects on clothing, such as belts, zip fasteners,
rivets or similar, can also leave permanent scratches and rough
marks on the surface of the leather.Note
•
Use a suitable impregnating cream wi th ultra-violet protection at
regular intervals and after cleaning. This cream will nourish and
moisturise the leather, keep it supple and able to breathe. In addi-
tion, it will also help to protect the surface of the leather.

Working on components in the engine compartment
Extra caution is necessary when working on components
in the engine compartment.Always be aware of the danger of injury and scalding as well as the
risk of accident or fire when working in the engine compartment
(e.g. when checking and refilling fluids). Always observe the warn-
ings listed below and follow al l normal safety precautions. The
engine compartment of any motor vehicle is a potentially
hazardous area . ⇒ .
WARNING
•
Switch off the engine.
•
Remove the ignition key.
•
Apply the parking brake.
•
Put the gear lever in neutral or selector in P.
•
Wait for the engine to cool down.
•
Keep children away from engine compartment.
•
Never spill fluids on hot engine components. These fluids can
cause a fire (e.g. radiator anti-freeze).
•
Take care not to cause short circ uits in the electrical system,
especially when working on the battery.
•
Do not touch the radiator fan when the engine is hot. The fan
may start running suddenly.
•
Do not unscrew the cap on the ex pansion tank when the engine
is hot. The cooling system is under pressure.
•
Protect face, hands and arms by covering the cap with a large,
thick rag to protect against escaping coolant and steam.
•
If any tests have to be performed with the engine running,
there is an extra safety risk from the rotating parts, such as the
drive belts, alternator and radiator fan, etc., and from the high-
voltage ignition system.
•
Vehicles with automatic gearbox: Never open the throttle inad-
vertently (for instance by hand from the engine compartment) if a
gear is engaged while the vehicle is stationary with the engine
running. The vehicle could otherwise start moving immediately
and possibly cause an accident.
•
Observe the following a dditional warnings if work on the fuel
system or the electrical system is necessary:
−Always disconnect the battery.
− Do not smoke.
− Never work near naked flames.
− Always keep an approved fire extinguisher immediately
available.Caution
When topping up fluids make sure the correct fluid is put into the
correct filler opening. This can otherwise cause serious malfunc-
tions or engine damage.
For the sake of the environment
Inspect the ground un derneath your vehicle regularly so that any
leaks are detected at an early stag e. If you find oil spots or other
fluids, have your vehicle inspected by a qualified workshop.
Note
On right-hand drive vehicles* some of the containers / reservoirs
mentioned below are located on the other side of the engine
compartment.
