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.

Service information is made available as soon as  
possible after a model is introduced and can be

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.  
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.  
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  
305  
Accessories and technical changes  
manner. Please refer to your Warranty & Mainte-  
nance Booklet for more detailed information  
about vehicle maintenance.  
There is the risk of an accident if work on the  
vehicle is performed incorrectly. Serious in-  
juries may result. Having the vehicle serv-  
iced by an authorized Audi dealer or author-  
ized Audi Service Facility is recommended.  
Please refer to the engine compartment  
safety precautions described in ðpage 237.  
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.  
Note  
Maintenance and repair work generally requires  
special tools, measuring devices, and other  
equipment that is available to trained vehicle  
technicians in order to help ensure that your vehi-  
cle and all of its systems operate correctly, relia-  
bly, and safely. Performing work on the vehicle  
incorrectly can impair the operation and reliabili-  
ty of your vehicle and may void one or more of  
your vehicle's warranties.  
Maintenance work, repairs, technical modi-  
fications to the vehicle (such as installing  
additional equipment), or paint work that is  
not performed correctly can cause vehicle  
damage.  
The New Vehicle Limited Warranty does not  
cover damage or malfunctions if the recom-  
mended intended use of the vehicle and  
maintenance measures listed in the Audi  
Owner's Manual and the Warranty & Main-  
tenance Booklet were not followed.  
If emergency repairs must be performed,  
take your vehicle to an authorized Audi deal-  
er or authorized Audi Service Facility as soon  
as possible.  
Technical Modifications  
Interference with electronic components, their  
software, the wiring, and data transfer may cause  
malfunctions. Because of the way electronic com-  
ponents are interconnected, such malfunctions  
can also impair systems that are not directly in-  
volved. This means that you risk both a substan-  
tial reduction in the operational safety of your ve-  
hicle and increased wear of vehicle components.  
Audi is not liable for damage to the vehicle  
resulting from failure to comply with these  
guidelines.  
Some convenience functions, such as the conven-  
ience turn signal function, individual door open-  
ing function, and displays, can be reprogrammed  
using special workshop equipment. If functions  
are reprogrammed, the information and descrip-  
tions about these functions in this Owner's Man-  
ual may no longer apply to the changed func-  
tions. Audi recommends that an authorized Audi  
dealer or authorized Audi Service Facility perform  
and verify any reprogramming procedures.  
For the sake of the environment  
Regular maintenance can help protect the  
environment.  
Technical modifications to the vehicle can  
have a negative impact on fuel consumption  
and vehicle emissions.  
Tips  
Because of your vehicle's aluminum body de-  
sign, all service and repair procedures affect-  
ing the body should be performed by an au-  
thorized Audi dealer or authorized Audi Serv-  
ice Facility, who will perform the work accord-  
ing to Audi factory specifications. Only Audi  
Genuine Parts are used when Audi experts  
perform repair or service procedures. Failure

work are not performed correctly. The func-  
tionality of the airbags, the driver assistance  
systems, and the vehicle may be impaired.

Accessories and parts  
Introduction  
Consult with an authorized Audi dealer or author-  
ized Audi Service Facility before purchasing ac-  
cessories or replacement parts.  
Audi recommends using Audi Genuine Parts and  
Audi Genuine Accessories. Audi does not evaluate  
the reliability and suitability of products that are  
not Audi Genuine Parts or endorse them, even if  
the product is approved by a certified testing  
agency or government agency.  
Have all work performed by an authorized Audi  
dealer or authorized Service Facility. Audi recom-  
mends having all work performed by an author-  
ized Audi dealer or authorized Audi Service Facili-  
ty.  
Radio communications equipment  
A correctly-installed exterior antenna is required  
for operating radio equipment in the vehicle.  
Otherwise, the increased electromagnetic waves  
can cause malfunctions in the vehicle. Observe  
the regulations in the country where the vehicle  
is being operated and the instructions from the  
radio equipment manufacturer.  
An authorized Audi dealer or authorized Audi  
Service Facility can inform you about installation  
options and radio communications equipment.  
WARNING  
Installing unapproved accessories or incor-  
rect replacement parts can cause vehicle  
damage and can increase the risk of an acci-  
dent.  
Never attach accessories, such as phone  
holders or cup holders, to the airbag covers  
or within the airbag deployment zone, be-  
cause this increases the risk of injury if the  
airbag deploys.  
On vehicles that have factory-installed li-  
cense plate brackets on the front of the ve-  
hicle, the brackets may only be replaced  
with ones that are the same size and made
