engine MAZDA MODEL 6 2020 Owner's Manual (in English)

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, th ey could affect your vehicle's
performance or safety systems; the Mazda warranty doesn't cover this. Before you install
any non-genuine parts or accessories, consult an Authorized Mazda Dealer.
WA R N I N G
Always consult an Authorized Mazda Dealer before you install non-genuine parts or
accessories:
Improperly designed parts or accessories coul d seriously affect your vehicle's performance or
safety systems. This could cause you to have an accident or increase your chances of injuries
in an accident.
Be very careful in choosing and installing add-on electrical equipment, such as mobile
telephones, two-way radios, stereo systems, and car alarm systems:
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/TCS/DSC inactivation, or a fire in the vehicle.
Mazda assumes no responsibility for death, injury, or expenses that may result from the
installation of add- on non-genuine parts or accessories.

WA R N I N G
Never Exceed Axle Weight Rating Limits:
Exceeding the Safety Certification Label axle weight rating limits is dangerous and could
result in death or serious injury as a result of substandard vehicle handling, performance,
engine, transmission and/or structural damage , serious damage to the vehicle, or loss of
control.
Always keep the vehicle within the axle weight rating limits.

GCW
GCW (Gross Combination Weight) is the weight of the loaded vehicle (GVW).

GCWR (Gross Combination Weight Rating) is the maximum allowable weight of the
vehicle - including all cargo and passengers - that the vehicle can handle without risking
damage. The GCW must never exceed the GCWR.

WA R N I N G
Never Exceed GVWR or GAWR Specifications:
Exceeding the GVWR or the GAWR specified on the
certification label is dangerous. Exceeding
any vehicle rating limitation could result in a serious accident, injury, or damage to the
vehicle.
Do not use replacement tires with lower load carrying capacities than the originals because
they may lower the vehicle's GVWR and GAWR limitations. Replacement tires with a higher
limit than the originals do not increase the GVWR and GAWR limitations.
Never exceed the GVWR or the GAWR specified on the certification label.
