Your vehicle and the environment

Running in

A new vehicle should be run in over a distance of 1,500 km. For the

first 1,000 km the engine speed should not exceed 2/3 of the

maximum permissible engine speed – do not use full throttle and do

not tow a trailer or caravan. From 1,000 to 1,500 km you can gradu-

ally increase the engine rpm and road speed.

During its first few hours of running, the internal friction in the

engine is greater than later on when all the moving parts have

bedded down.

How the vehicle is driven for the first 1,500 km also influences the

engine quality. After the first 1,500 km you should continue driving

at moderate engine speeds, in particular when the engine is cold.

This helps to reduce wear and tear on the engine and increases the

potential mileage which can be covered by the engine.

You should also avoid driving with the engine speed too low.

Change down to a lower gear when the engine no longer runs

“smoothly”. Excessively high engine speeds are prevented by an

automatic rev limiter.

Emission control systems

Catalytic converter

Applies to vehicles with petrol engine: The vehicle must only be

used with unleaded petrol, otherwise the catalytic converter will be

destroyed.

Never run the tank completely dry. The irregular fuel supply can

cause misfiring, which would allow unburnt fuel to enter the

exhaust system, which could cause overheating and damage the

catalytic converter.

Diesel particulate filter

Applies to vehicles with diesel engine: The diesel particulate filter

can filter out almost all soot particles contained in the exhaust gas.

In normal driving conditions the filter is self-cleaning. Should the

self-cleaning function of the filter not be able to operate, e.g. when

the vehicle is continuously used only for short trips, the filter

becomes obstructed with soot and the symbol  for the diesel

particulate filter lights up ⇒ page 37.

WARNING

• Because of the high temperatures which can occur in the emis-

sion control system (catalytic converter or diesel particulate

filter), do not park the vehicle where the exhaust can come into

contact with flammable materials under the car (e.g. on grass or

at the forest edge). - Fire hazard!

• Do not apply any underseal agents in the area around the

exhaust system - fire hazard!

Driving abroad

Changing over headlight dip settings

The asymmetric low beams of the headlights are designed to light

up the near side of the road more intensely. If you drive in a country

where traffic drives on the opposite side of the road to the home

country, this will dazzle oncoming traffic.

Headlights with halogen bulbs: To avoid dazzling oncoming traffic

you can apply opaque stickers to certain parts of the headlight

lenses.

Headlights with xenon gas-discharge bulbs*: The headlight dip

settings must be changed to avoid dazzling oncoming traffic. For

safety 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 pollution

Fuel 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

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 setting), the rear window heating and the seat

heating*.

Environmental compatibility

Environmental protection is a top priority in the design, choice of

materials and production of your new Audi.

Design measures for economical recycling

• Joints and connections designed for ease of dismantling

• Modular construction to facilitate dismantling

• Increased use of single-grade materials

• Plastic parts and elastomers are labelled in accordance with ISO

1043, ISO 11469 and ISO 1629

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

• CFC-free refrigerant in air conditioner

Compliance with the laws prohibiting the use of: Cadmium,

asbestos, lead, mercury and chrome VI.

Manufacturing methods

• Using recycling material for manufacturing plastic parts

• Solvent-free cavity sealing

• Solvent-free wax for protecting the vehicles in transit

• Solvent-free adhesives

• No CFCs used in production

• Surplus materials used extensively for energy conversion and

building materials

• Overall water consumption reduced

• Heat recovery systems

• Water-soluble paint
