Check and adjustment conditions

WARNING: This page does not describe the selected car, but rather 15 other vehicles, including the 2008 Audi S4, 2008 Audi RS 4, 2008 Audi A4, 2007 Audi S4, and 2007 Audi RS 4. However, it is still accessible from the selected car via links, so may be relevant.

Tire pressure OK.
Lenses must not be damaged or dirty.
Reflectors and bulbs OK.
Vehicle must be properly loaded.

Load: Vehicle must be loaded with one person on the drivers seat, weighing 75 kg, otherwise vehicle must be empty (curb weight).

The curb weight is the weight of the vehicle ready for operation with completely filled fuel tank (at least 90%), including the weight of all equipment items carried for operation (e.g. spare wheel, tool, vehicle jack, fire extinguisher etc.).

If the fuel tank is not at least 90% full, adjust the weight as follows:

Read fuel level from fuel gauge. Calculate additional weight needed using the following table. Place extra weight in luggage compartment.

Tank filling

Fuel level according to fuel gauge	Additional weight in kg
1/4	52
1/2	35
3/4	17
Full	0

Example:

If the fuel tank is half full, place a weight of 35 kg in the luggage compartment.

NOTE:

For additional weight use containers filled with water. A container filled with 5 liters of water weighs approx. 5kg.

Vehicle must be rolled for several meters or the front and rear suspension must be bounced several times so that the springs settle.

Vehicle and headlamp adjuster must be on a level surface operating instructions for headlamp adjuster.
Vehicle and headlamp adjuster must be aligned.

Ensure headlight adjuster is about 30 cm in front of headlight.

Inclination must be set.

Inclination measurements are stamped in "%" at top of headlamp. The headlamps must be adjusted according to these measurements. Percentage information is based on a projection distance of 10 meters. For example: inclination of 1.0 % converts to approx. 10 cm.
