Special parking situationsApplies to vehicles: with parking system advancedParking next to an obstacle
When parking next to an obstacle it is important to keep
sufficient distance at the side.When using “Parking mode 2” you can park your vehicle very close
to the kerb of the pavement ⇒page 143, fig. 157.
However, if you are parking, for example, next to a wall, you must
keep a greater distance to the side in order to avoid any collision
damage. Position the long side of the blue area marking in such a
way that there is sufficient distance to the kerb. The area marking
must NOT touch the kerb ⇒fig. 168.
You also have to steer in the opposite direction a lot earlier. This
means that the blue curve ⇒page 146, fig. 163 must not touch the
kerb - make sure there is a sufficient distance to the kerb ⇒.
WARNING
•
Please make sure you keep a sufficient distance between the
vehicle and any obstacles to make sure that the exterior mirror or
edge of the vehicle do not collide wi th the obstacle (accident risk).

Your vehicle and the environment
206safety reasons, the dip settings may only be changed by a qualified
workshop.
For further information, please consult an Audi dealer or other qual-
ified workshop.
Unleaded petrol
A car with catalytic converter must not be run with leaded petrol
⇒ page 205 . Before driving abroad make sure that unleaded petrol
is available there.How to improve economy and minimise pollutionFuel economy, environmental impact and wear on the engine,
brakes and tyres depend largely on the way you drive the vehicle. By
adopting an economical driving style and anticipating the traffic
situation ahead, you can reduce fuel consumption by 10-15%. The
following section gives you some tips on lessening the impact on
the environment and reducing your operating costs at the same
time.
Anticipate well in advance
A car uses most fuel when accelerating. If you anticipate hazards
and speed changes well in advance, you will need to brake less and
thus accelerate less. Wherever possible, let the car slow down grad-
ually with a gear engaged , for instance when you can see that the
next traffic lights are red. This takes advantage of the engine
braking effect, reducing wear on the brakes and tyres. Emissions
and fuel consumption will drop to zero due to the overrun fuel cut-
off.
Change gear early to save fuel
An effective way of saving fuel is to change up quickly through the
gears. Running the engine at high rpm in the lower gears uses an
unnecessary amount of fuel. Manual gearbox:
Shift up to second gear as soon as possible. If
possible, we recommend shifting up to the next gear at approx.
2,000 rpm.
Automatic gearbox: Press the accelerator slowly and avoid using
the “kick-down” feature.
Avoid driving at high speed
Avoid travelling at top speed. Fuel consumption, exhaust emissions
and noise levels all increase very rapidly at higher speeds. Driving at
moderate speeds will help to save fuel.
Do not let the engine idle for longer than necessary
It is worthwhile switching off the engine when waiting in a traffic
jam, at level crossings or at traffic lights with a long red phase. The
fuel saved after only 30 - 40 seconds is greater than the amount of
fuel needed to restart the engine.
The engine takes a very long time to warm up when it is running at
idling speed. Mechanical wear and pollutant emissions are also
especially high during this initial warm-up phase. It is therefore best
to drive off immediately after starting the engine. Avoid running the
engine at high speed.
Regular servicing
Regular servicing can establish a basis for good fuel economy
before you start driving. A well-serviced engine gives you the
benefit of improved fuel efficiency as well as maximum reliability
and an enhanced resale value. A badly tuned engine can consume
up to ten percent more fuel than necessary.
Avoid short trips
The engine and emission control system need to reach their proper
working temperature in order to minimise fuel consumption and
emissions.
A cold engine uses disproportionately more fuel. The engine only
reaches its working temperature after about four kilometres, when

Towing a trailer
210•
In low outside temperatures , both the towing vehicle and the
trailer should be fitted with winter tyres.
WARNING
It is essential that you adjust your speed to suit the weather, road
and traffic conditions. Do not let the trailer stabilisation system
tempt you into taking any risks wh en driving – this can cause acci-
dents.•
The ESP and trailer stabilisatio n system cannot defy the laws
of physics. This should be kept in mind, particularly on slippery
and wet roads and when towing a trailer with a light load.
•
The trailer stabilisation system is functional, regardless of
whether the trailer has a mechanical overrun brake or not.
•
The trailer stabilisation system is not always able to detect
swaying of trailers with a light load and will therefore not inter-
vene.
•
A trailer can still “jack-knife” on slippery roads with little grip,
even if the towing vehicle is eq uipped with the trailer stabilisation
system.
•
Trailers with a high centre of gravity may even tip over before
they start to sway sideways.
•
If you are not towing a trailer, but the trailer socket is being
used (e.g. for an illuminated bicycl e rack), the trailer stabilisation
system may be activated in extreme driving conditions.
•
Please note the additional information and warnings
⇒ page 210 .
Notes on towing
Driving with a trailer always requires extra care.Weight distribution
Try to avoid towing a loaded trailer with an unladen vehicle. If this
cannot be avoided, drive extra slowly to allow for the unbalanced
weight distribution.
Speed
The stability of the car and trailer is reduced with increasing speed.
For this reason it is advisable not to drive at the maximum permis-
sible top speed in unfavourable road, weather or wind conditions.
This applies especially on a downhill gradient.
You should always reduce speed immediately if the trailer shows
the slightest sign of swaying. Never try to stop the swaying by accel-
erating further.
Always brake in good time. If the trailer has an overrun brake, apply
the brakes gently at first and then firmly. This will prevent the jerking
that can be caused by the trailer wheels locking. Change down in
good time before going down a steep hill so that you can use the
engine braking effect to slow down the vehicle.
Swaying and pitching can be reduced by stabiliser aids. We recom-
mend having stabiliser aids installed when towing trailers with a
high trailer weight. They can be purchased and installed at an Audi
dealer.
Overheating
When climbing long hills in hot weather with the engine running
fast in low gear, you should keep an eye on the coolant temperature
gauge ⇒page 11 . Reduce speed immediately if the needle moves to
the top end of the scale. If the temperature warning lamp
 in the
instrument cluster should start flashing, stop the car and let the
engine cool down by running it at idling speed for a few minutes.

WARNING
•
Ensure that no oil comes into contact with hot engine compo-
nents when topping up: th is could cause a fire.
•
Wash your skin thoroughly if it comes into contact with engine
oil.Caution
•
The oil level must never be above area , as this may result in
damage to the catalytic converter or to the engine. Contact a quali-
fied workshop to extract the engine oil if necessary.
•
No additives should be used with engine oil. Any damage caused
by the use of such additives woul d not be covered by the factory
warranty.For the sake of the environment
•
Never pour oil down drains or into the ground.
•
Always observe statutory requ irements when disposing of
empty oil canisters.
Cooling systemCoolant
The purpose of the coolant is to carry heat away from the
engine. The correct amount of anti-freeze is important to
prevent the cooling system from freezing in winter.The cooling system is filled for life at the factory, so the coolant does
not need to be changed. The coolant consists of a mixture of water
and anti-freeze additive G12+. This is a glycol-based anti-freeze with
anti-corrosion additives.
Anti-freeze additive
The amount of anti-freeze additive required depends on the temper-
atures to be expected in the winter season. If the anti-freeze concen-
tration is too low the coolant can freeze, resulting in failure of the
cooling system and heater.
The cooling system is filled at the factory with the correct amount of
anti-freeze for the country concerned.
In most cases the mixture consists of 60% water and 40% additive.
This mixture gives the necessary antifreeze protection down to –
25 °C and protects the alloy part s of the cooling system against
corrosion. It also prevents scaling an d raises the boiling point of the
coolant.
Countries with warm climate
The coolant concentration must not be reduced by adding plain
water, even in the summer or in warm climates. The concentration
of the anti-freeze additive must always be at least 40%.
Countries with cold climate
If greater anti-freeze protection is required in very cold climates, the
proportion of the anti-freeze additive G12+ can be increased. A
concentration of 60% offers protection down to about -40 °C. The
concentration of the antifreeze additive must not be more than 60%,

Checking and topping up fluids
238Brake fluidChecking brake fluid level
The brake fluid level can be checked at a glance.– Check the fluid level on the brake fluid reservoir
⇒fig. 228. It should always be between the “MIN” and
“MAX” marks.In right-hand drive vehicles the brake fluid reservoir is on the other
side of the engine compartment.
The fluid level may drop slightly after a period of time due to the
automatic compensation for brake pad wear. This is quite normal.
However, if the level goes down noticeably in a short time, or drops
below the “MIN” mark, there may be a leak in the brake system. If
the fluid level in the reservoir is too low, this will be indicated by the
brake warning lamp ⇒page 31 . If this should happen, take the car
to a qualified workshop immediately and have the brake system
inspected.
Changing brake fluid
When required, the brake fluid should be changed by a
competent mechanic with the proper equipment.Brake fluid gradually absorbs moistu re 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 the safety of the car – risk of acci-
dent.Caution
Please note that brake fluid will attack the paintwork on contact.

Wheels and tyres
244
– The tyre pressures should only be checked when the tyres are cold . The slightly raised pressures of warm tyres
must not be reduced.
– The pressures must be altered to suit major changes in the load being carried.
– Avoid fast cornering and hard acceleration.
– Inspect the tyres for irregular wear from time to time.Tyre pressure and vehicle loading
The tyre pressure must be adjusted according to the load the vehicle
is carrying. We recommend adhering to the tyre pressure specifica-
tions for a maximum load. The tyre inflation pressures are listed on
a sticker on the end face of the driver's door ⇒page 243, fig. 231.
However, if you prefer an extra-smooth ride and the vehicle is not
fully loaded, you can select the tyre pressure for a normal load (no
more than three people travelling in the vehicle). However, should
you wish to drive with a full load you must increase the tyre pressure
to the specified maximum.
Under-inflation or over-inflation will reduce the life of the tyres
considerably and also impair the car's handling. Correct inflation
pressures are very important, especially at high speeds. The pres-
sures should therefore be checked at least once a month and before
starting a journey.
Do not forget the spare wheel* when checking the tyre pressures.
Keep the spare tyre inflated to the highest pressure required for the
road wheels.
Driving habits
Fast cornering, heavy acceleration and hard braking (squealing
tyres) all increase tyre wear. Wheel balancing
The wheels on new vehicles are balanced. However, various factors
encountered in normal driving can cause them to become unbal-
anced, which results in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause
excessive wear on steering, suspension and tyres. A wheel must
also be rebalanced when a new tyre is fitted or if a tyre is repaired.
Incorrect wheel alignment
Incorrect wheel alignment causes excessive tyre wear, impairing the
safety of the vehicle. If you notice excessive tyre wear, contact your
Audi dealer.
WARNING
•
Always adapt the tyre pressure
accordingly when the vehicle
load changes.
•
Under-inflated tyres flex more and can overheat at continuous
high speeds. This can cause tread separation and tyre blow-out,
which could result in an accident.For the sake of the environment
Under-inflated tyres will increase the fuel consumption.

Technical data
Tread wear indicators
The tread wear indicators show the condition of the tyre
treads.The original tyres on your vehicle have 1.6 mm high “tread wear
indicators” ⇒fig. 232 running across the tread. Depending on the
make, there will be 6 to 8 of them spaced at equal distances around
the tyre. Markings on the tyre side wall (for instance the letters “TWI”
or a triangle) indicate the positions of the tread wear indicators.
The minimum tread depth required by law in Germany is 1.6 mm
(measured in the tread grooves next to the tread wear indicators).
Other specifications may apply in export countries.
WARNING
To avoid putting safety at risk, the tyres must be replaced at the
latest when the tread is worn do wn to the tread wear indicators.•
Especially in difficult driving conditions such as wet or icy
roads, it is important that the ty res have sufficient tread depth.
The tread depth should same on the tyres of both the front and the
rear axles.
•
The decrease in drivin g safety due to insufficient tread depth is
particularly evident in vehicle handling, when there is a risk of aquaplaning in deep puddles of wa
ter and when driving through
corners. Braking is also adversely affected.
•
The speed has to be adapted accor dingly, otherwise there is a
risk of losing control over the vehicle.
Changing wheels roundTo ensure that the wear is equal on all tyres the wheels should be
changed round from time to time according to the system
⇒ fig. 233. All the tyres will then last for about the same time.Replacing wheels and tyres
It is important to use the correct wheels and tyres when
replacement is necessary.– All four wheels must be fitted with tyres of the same type,
size (rolling circumference) and preferably the same
tread pattern.
– If possible, tyres should be replaced at least in pairs and not individually (i.e. both front tyres or both rear tyres
together).

Self-help
260•
Seek professional assistance if th e repair of a tyre puncture is
not possible with the sealing compound.
•
If tyre pressure is less than 1.3 bar after driving about 10
minutes, the tyre is too badly damaged. Do not drive on. You
should obtain professional assistance.Caution
Take special care if you have to repair a tyre on a gradient.
Note
•
Do not use the compressor for longer than 6 minutes at a time,
as it could overheat. When the compressor has cooled down, you
can use it again.
•
If tyre sealant should leak out, leave it to dry and then pull it off
like foil.
•
After carrying out a tyre repair remember to buy a new tyre
sealant can at a qualified workshop. This will ensure that the Tyre
Mobility System is operative again.
•
Please observe the relevant regulations.
Changing a wheelPreparations
Some preparations are necessary before changing a
wheel.– If you have a flat tyre, stop the car well away from moving traffic. Choose a location that is as level as possible.– All passengers should
leave the car. They should wait in
a safe place (for instance behind the roadside crash
barrier).
– Apply the parking brake to stop the vehicle moving acci-
dentally.
–Engage first gear (manual gearbox) or move selector
lever to position P (automatic gearbox).
– When towing a trailer: unhitch the trailer from your vehicle.
– Take the tools ⇒ page 255 and the spare wheel*
⇒ page 256 out of the luggage compartment.
WARNING
If you have a puncture in moving traffic, switch on the hazard
warning lights and place the warning triangle in a visible location.
This is for your own safety and also warns other road users.
Caution
If you have to change the tyre on a gradient, block the wheel oppo-
site the wheel being changed by placing a stone or similar object
under it to prevent the vehicle from rolling away.
Note
Please observe the relevant regulations.How to change a wheel
Change the wheel as described below.–Pull off the hub cap . Also refer to ⇒page 261, “Hub
caps”.
