General recommendations
Why is your seat adjustment so important?
The safety belts and the airbag system can only provide
maximum protection if the front seats are correctly
adjusted.
There are various ways of adjusting the front seats to provide safe and comfortable support for the driver and the front passenger.
Adjust your seat properly so that:
• you can easily and quickly reach all the switches and controls in
the instrument panel
• your body is properly supported thus reducing physical stress
and fatigue
• the safety belts and airbag system can offer maximum protec ­
tion=> page 218.
In the following sections, you will see exactly how you can best
adjust your seats.
There are special regulations and instructions for installing a child seat on the front passenger's seat. Always follow the information
regarding child safety provided
in=> page 243, "Child Safety".
& WARNING
Incorrect seating position of the driver and all other passengers
can result in serious personal injury.
• Always keep your feet on the floor when the vehicle is in motion
- never put your feet on top of the instrument panel, out of the
window or on top of the seat cushion. This applies especially to
the passengers. If your seating position is incorrect, you increase
the risk of injury in the case of sudden braking or an accident. If
& WARNING (continued)
the airbag inflates and the seating position is incorrect, this could
result in personal injury or even death.
• It is important for both the driver and front passenger to keep
a distance of at least 10 inches (25 cml between themselves and
the steering wheel and/or instrument panel. If you're sitting any
closer than this, the airbag system cannot protect you properly. In
addition, the front seats and head restraints must be adjusted to
your body height so that they can give you maximum protection.
• Always try to keep as much distance as possible between your­
self and the steering wheel or instrument panel.
• Do not adjust the driver's or front passenger's seat while the
vehicle is moving. Your seat may move unexpectedly, causing
sudden loss of vehicle control and personal injury. If you adjust
your seat while the vehicle is moving, you are out of position. •
Driver's seat
The correct seat position is important for safe and relaxed
driving.
We recommend that you adjust the driver's seat in the
following manner:
- Adjust the seat in fore and aft direction so that you can
easily push the pedals to the floor while keeping your knees slightly
bent => & in "Why is your seat adjustment
so important?".
- Adjust the seatback so that when you sit with your back
against the seatback, you can still grasp the top of the
steering wheel.

Roof rack
First things first
A roof rack can be fitted to carry additional luggage on
the roof.
- Always read and follow the instructions provided by the
roof rack manufacturer when the roof rack system must
be installed.
If a roof rack or similar luggage carrying equipment is to be
installed, please note the following:
• To enhance the vehicle's streamlined design, rain gutters have
been molded into the roof. It is not possible to use normal roof
racks. Only install a roof rack specifically designed for your model
A8. Contact the nearest Audi dealer for information on approved modular roof racks for your vehicle.
Controls and equip­
ment
• These approved roof racks are the basis for a complete roof rack
system. Additional attachments for the basic roof rack are neces ­
sary to safely transport luggage, bicycles, surf boards, skis or small
boats. All necessary hardware for these systems is available at your
authorized Audi dealer.
• We recommend that you keep the installation instructions for
your roof rack system together with your Owner's l iterature in the
vehicle.
When should the roof rack be removed?
• Before going through an automatic car wash (it is best to ask the
car wash operator for advice)
• When not in use, to reduce fuel consumption, wind noise and to
guard against theft.
& WARNING
• Use of an unapproved roof rack or incorrect mounting of an
approved roof rack can cause the roof rack or the items attached
to it to fall off the roof onto the road.
• Objects falling from the roof of a vehicle can cause a crash and
personal injury.
• Only mount the system between the markings shown in
~ page 104, fig. 109.
• The roof rack system must be installed exactly according to the
instructions provided.
(D Note
• Your vehicle warranty does not cover any damages to the vehicle
caused by using roof racks or mounting struc tures not approved by
Audi for your vehicle. The same applies to damage resulting from
incorrect roof rack installation.
• Always check the roof rack mountings and hardware before each
trip and during a trip to make sure everything is securely tightened.
