fuel consumption will return to a normal level. This is the reason
why we recommend avoiding short trips wherever possible.
Maintain the correct tyre pressures
Always make sure the tyres are inflated to the correct pressures
⇒
page 243 to save fuel. If the tyre pressures are just 0.5 bar too low,
this can increase the fuel consumption by as much as 5 %. Due to
the greater rolling resistance, under-inflation also increases tyre
wear and impairs handling.
Do not use winter tyres all through the year; they will increase fuel
consumption by up to 10 %.
Avoid carrying unneccessary loads
Every kilo of extra weight will increase the fuel consumption, so it is
worth checking the luggage compartment occasionally to make
sure that no unnecessary loads are being transported.
A roof carrier is often left in place for the sake of convenience, even
when it is no longer needed. At a speed of 100-120 km/h your car will
use about 12 % more fuel as a result of the extra wind resistance
caused by the roof carrier - even when it is empty.
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*.

Choice of materials
•
Nearly all materials used can be recycled
•
Similar types of plastics grouped together for easy recycling
•
Recycled materials used in manufacture
•
Reduced vapour emissions from plastics
•

Wheels and tyresWheelsGeneral notes–When driving with new tyres , be especially careful during
the first 500 km.
– If you have to drive over a kerb or similar obstacle, drive very slowly and as near as possible at a right angle to the
kerb.
– Inspect the tyres regularly for damage (cuts, cracks or blisters, etc.). Remove any foreign bodies embedded in
the treads.
– Damaged wheels and tyres must be replaced immedi- ately.
– Keep grease, oil and fuel off the tyres.
– Replace any missing valve caps as soon as possible.
– Mark the wheels before taking them off so that they rotate in the same direction when put back.
– When removed, the wheels or tyres should be stored in a cool, dry and preferably dark place.New tyres
New tyres do not give maximum grip straight away and should
therefore be “run in” by driving carefully and at moderate speeds for
about the first 500 km. This will al so help to make the tyres last
longer.
The tread depth of new tyres may vary, according to the type and
make of tyre and the tread pattern. Concealed damage
Damage to tyres and rims is often not readily visible. If you notice
unusual
vibration or the car pulling to one side , this may indicate
that one of the tyres is damaged. Reduce speed immediately if there
is any reason to suspect that damage may have occurred. Inspect
the tyres for damage. If no external damage is visible, drive slowly
and carefully to the nearest qualified workshop and have the car
inspected.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the direction of rotation on
tyres with directional tread. Always note the direction of rotation
indicated when mounting the wheel. This guarantees optimum grip
and helps to avoid aquaplaning, excessive noise and wear.
Tyre service life
Correct inflation pressures and sensible driving habits
will increase the service life of your tyres.– Check the tyre pressures at least once a month.

– 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.

–Loosen the wheel bolts ⇒ page 261 .
– Raise the car with the jack* ⇒page 262 .
– Ta k e o f f the wheel with the flat tyre and then put on the
spare wheel* ⇒page 263 .
– Lower the vehicle to the ground.
– Tighten the wheel bolts firmly i n d i a g o n a l s e qu e n c e w i t h
the box spanner ⇒page 261 .
–Fit the hub cap back on.After changing a wheel
What you must do after changing a wheel.– Place the wheel with the defective tyre in the spare wheel
well and secure it.
– Put the tools and the jack* back in the luggage compart- ment.
–The inflation pressure of the newly fitted spare tyre must
be checked as soon as possible.
–Have the tightening torque of the wheel bolts checked as
soon as possible with a torque wrench. The correct tight-
ening torque is 120 Nm.
– Have the flat tyre replaced as quickly as possible.
Note•
If you notice that the wheel bolts are corroded and difficult to
turn when changing a wheel, they must be replaced before having
the tightening torque checked.
•
In the interest of safety, drive at moderate speeds until the tight-
ening torque of the wheel bolts has been checked.
Hub caps
The hub caps must be remo ved for access to the wheel
bolts.Removing
– Insert the hook (provided in the vehicle's tool kit) in the
hole in the hub cap.
–Pull off the hub cap ⇒fig. 241.Loosening and tighten ing the wheel bolts
The wheel bolts must be loosened before raising the
vehicle.
