Driving in other
countries
Government regulations in the United States and
Canada require motor vehicles to comply with
emissions regulations and safety standards.
Therefore, vehicles that were produced for the
U.S. and Canadian markets are different from
vehicles produced for other countries.
If you plan to use your vehicle outside of the
United States or Canada, it is possible that:
— Fuel may have a significantly lower octane rat-
ing. Unsuitable fuels can cause engine damage.
— Proper maintenance and repair work may not
be possible because special service equipment,
tools, or measuring devices needed for your ve-
hicle may not be available.
— Replacement parts may not always be availa-
ble.
— Navigation systems for vehicles built for the
U.S.A. and Canada will not necessarily work in
Europe, and may not work in other countries.
() Note
Audi is not liable for damage to the vehicle re-
sulting from these country-specific differen-
ces.
Maintenance, repairs,
and technical modifi-
cations
Observe the safety precautions > page 221, Gen-
eral information and > page 264, Raising the ve-
hicle.
General information
Due to the increasing complexity of technology in
these vehicles, as well as the safety and environ-
mental standards that apply, you can only per-
form a very limited amount of repairs and modifi-
cations to the vehicle yourself.
Proof of maintenance work may be required to
submit a claim within the warranty period.
We recommend that you have your vehicle serv-
iced by an authorized Audi dealer or authorized
Audi Service Facility and that Audi Genuine Parts
and Audi Genuine Accessories are used. This
helps to ensure that your vehicle's functionality,
performance, and safety are not impaired.
Maintenance and repairs
Your vehicle was designed to help keep mainte-
nance requirements to a minimum. Some regular
maintenance is required to help ensure that your
vehicle runs in a safe, economical, and reliable
manner. Please refer to your Warranty & Mainte-
nance Booklet for more detailed information
about vehicle maintenance.
When operating the vehicle under more extreme
operating conditions, for example when outside
temperatures are very low or in very dusty envi-
ronments, certain maintenance should be per-
formed between the specified intervals.
