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.
Catalytic converter
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.
WARNING
• Because of the high temperatures which can occur in the cata-
lytic converter, do not park the vehicle where the catalytic
converter 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. 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 work-
shop.
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 195. Before driving abroad make sure that unleaded petrol
is available there.
