Outside the United States
Government regulations in the United States require that automobiles meet specific
emission regulations and safety standards. Therefore, vehicles built for use in the United
States may differ from those sold in other countries.
The differences may make it difficult or even impossible for your vehicle to receive
satisfactory servicing in other countries. We strongly recommend that you NOT take your
Mazda outside the United States. However, in the event that you are moving to Canada
permanently, Mazda vehicles built for use in the United States could be eligible for
exportation to Canada with specific vehicle modifications to comply with the Canadian
Motor Vehicle Safety requirements (CMVSS).
NOTE
The above is applicable for a permanent import/export situation and not related to
travelers on vacation.
You may have the following problems if you do take your vehicle outside of the United
States:
lRecommended fuel may be unavailable. Any kind of leaded fuel or low-octane fuel will
affect vehicle performance and damage the emission controls and engine.
lProper repair facilities, tools, testing equipment, and replacement parts may not be
available.
Please refer to your Manufacturer's Warranty Booklet for more information.

Add-On Non-Genuine Parts and Accessories
Non-genuine parts and accessories for Mazda vehicles can be found in stores.
These may fit your vehicle, but they are not approved by Mazda for use with Mazda
vehicles. When you install non-genuine parts or accessories, they could affect your
vehicle's performance or safety system; the Mazda warranty doesn't cover this. Before you
install any non-genuine parts or accessories, consult an Authorized Mazda Dealer.
WARNING
Installation of Non-Genuine Parts or Accessories:
Installation of non-genuine parts or accessories is dangerous. Improperly designed
parts or accessories could seriously affect your vehicle's performance or safety system.
This could cause you to have an accident or increase your chances of injuries in an
accident. Always consult an Authorized Mazda Dealer before you install non-genuine
parts or accessories.
Add-On Electrical and Electronic Equipment:
Incorrectly choosing or installing improper add-on equipment or choosing an
improper installer is dangerous. Essential systems could be damaged, causing engine
stalling, air-bag (SRS) activation, ABS inactivation, or a fire in the vehicle.
Be very careful in choosing and installing add-on electrical equipment, such as mobile
telephones, two-way radios, stereo systems, and car alarm systems.
Mazda assumes no responsibility for death, injury, or expenses that may result from the
installation of add-on non-genuine parts or accessories.
