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 rating.

    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 vehicle may not be available.
  • Replacement parts may not always be available.
  • 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 resulting from these country-specific differences.

Maintenance, repairs, and technical modifications

General information

Due to the increasing complexity of technology in these vehicles, as well as the safety and environmental standards that apply, you can only perform a very limited amount of repairs and modifications 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 serviced 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 maintenance 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 & Maintenance 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 environments, certain maintenance should be performed between the specified intervals.

Usually maintenance and repair work requires special tools, measuring devices, and other equipment that is available to trained vehicle technicians in order to help ensure that your vehicle and all of its systems operate correctly, reliably, and safely. Performing work on the vehicle incorrectly can impair the operation and reliability of your vehicle and may void one or more of your vehicle's warranties.

Technical Modifications

Interference with electronic components, their software, the wiring, and data transfer may cause malfunctions. Because of the way electronic components are interconnected, such malfunctions can also impair systems that are not directly involved.

This means that you risk both a substantial reduction in the operational safety of your vehicle and increased wear of vehicle components.

Some convenience functions, such as the convenience turn signal function, individual door opening function, and displays, can be reprogrammed using special workshop equipment. If functions are reprogrammed, the information and descriptions about these functions in this Owner's Manual may no longer apply to the changed functions.

Audi recommends that an authorized Audi dealer or authorized Audi Service Facility perform and verify any reprogramming procedures.

WARNING

Maintenance work, repairs, or technical modifications to the vehicle (such as installing additional equipment) that is not performed correctly can cause serious injuries and increase the risk of an accident.

WARNING

The motor compartment in any motor vehicle is a potentially dangerous area and can cause serious personal injury.

  • Always use extreme caution when doing any work in the motor compartment. Always follow commonly accepted safety practices and use common sense. Never risk personal injury.
  • Never perform any work in the motor compartment unless you know exactly how to carry out the job and have the correct technical information and the correct tools.
  • If you are uncertain about what to do, have the work performed by an authorized Audi dealer, an authorized Audi Service Facility, or another qualified workshop. Serious personal injury may result from improperly performed work.

Note

  • Maintenance work, repairs, or technical modifications to the vehicle (such as installing additional equipment) that is not performed correctly can cause vehicle damage.
  • The New Vehicle Limited Warranty does not cover damage or malfunctions if the recommended intended use of the vehicle and maintenance measures listed in the Audi Owner's Manual and the Warranty & Maintenance Booklet were not followed.
  • If emergency repairs must be performed, take your vehicle to an authorized Audi dealer or authorized Audi Service Facility as soon as possible.
  • Audi is not liable for damage to the vehicle resulting from failure to comply with these guidelines.

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.

For the sake of the environment

Certain components in your vehicle such as undeployed airbag modules, pretensioners and remote control batteries may contain Perchlorate Material - special handling may apply, See www.dtsc.ca.gov/hazardouswaste/ perchlorate. When the vehicle or parts of the restraint system including airbag modules and safety belts with pretensioners are scrapped, all applicable laws and regulations must be observed. Your authorized Audi dealer is familiar with these requirements and we recommend that you have your dealer perform this service for you.

Tips

Because of your vehicle's aluminum body design, all service and repair procedures affecting the body should be performed by an authorized Audi dealer or authorized Audi Service Facility, who will perform the work according to Audi factory specifications. Only Audi Genuine Parts are used when Audi experts perform repair or service procedures. Failure to use Audi Genuine Parts or Audi Genuine Accessories or performing repairs incorrectly may result in severe vehicle damage, such as corrosion.

Accessories and parts

Consult with an authorized Audi dealer or authorized Audi Service Facility before purchasing accessories or replacement parts. Audi recommends having your vehicle serviced by an authorized Audi dealer or authorized Audi Service Facility and using Audi Genuine Parts and Audi Genuine Accessories.

Audi does not endorse the use of products and accessories that it has not evaluated, even if the product is approved by a certified testing agency or government agency.

WARNING

  • Installing unapproved accessories or incorrect replacement parts can cause vehicle damage and can increase the risk of an accident.
  • Never attach accessories, such as telephone holders or cup holders, to the airbag covers or within the airbag deployment zone, because this increases the risk of injury if the airbag deploys.
  • On vehicles that have factory-installed license plate brackets on the front of the vehicle, the brackets may only be replaced with ones that are the same size and made of the same material. Do not install any license plate brackets on the front of vehicles that do not have factory-installed brackets.

    Otherwise, the function of the system could be impaired.

Note

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.
