Inspecting the Brake Fluid
WARNING
If the brake fluid level is low, have the
brakes inspected.
A low brake fluid level is dangerous. A
low level could indicate brake lining
wear or a brake system leak which
could cause the brakes to fail and lead
to an accident.
Inspect the fluid level in the reservoir
regularly. It should be kept between
the MAX and MIN lines.
The level normally drops with
accumulated distance, a condition
associated with wear of brake linings. If
it is excessively low, have the brake
system inspected by an Authorized
Mazda Dealer.

Before inspecting the brake fluid,
remove the hole cover.

Brake fluid reservoirReplenishing WindshieldWasher Fluid
WARNING
Use only windshield washer fluid or
plain water in the reservoir.
Using radiator antifreeze as washer
fluid is dangerous. If sprayed on the
windshield, it will dirty the windshield,
affect your visibility, and could result in
an accident.
Using Washer Fluid Without
Anti-freeze Protection in Cold
Weather:
Operating your vehicle in temperatures
below 4 ℃ (40 °F) using washer fluid
without anti-freeze protection is
dangerous as it could cause impaired
windshield vision and result in an
accident. In cold weather, always use
washer fluid with anti-freeze
protection.
CAUTION
Do not use soapy water or engine
antifreeze in the reservoir as it could
cause paint discoloration or pump
damage.
NOTE
State or local regulations may restrict
the use of volatile organic
compounds (VOCs), which are
commonly used as anti-freeze agents
in washer fluid. A washer fluid with
limited VOC content should be used
only if it provides adequate freeze
resistance for all regions and climates
in which the vehicle will be
operated.

Exterior Maintenance
WARNING
Dry off brakes that have become wet
by driving slowly, releasing the
accelerator pedal and lightly applying
the brakes several times until the
brake performance returns to normal.
Driving with wet brakes is dangerous.
Increased stopping distance or the
vehicle pulling to one side when
braking could result in a serious
accident. Light braking will indicate
whether the brakes have been
affected.
CAUTION
Before lifting the windshield wiper
blades off the windshield, always
follow the procedure for moving the
windshield wiper blades. Otherwise,
a wiper blade, wiper arm, or the
hood could be damaged.
Refer to the Replacing Windshield
Wiper Blade Rubbers section (page
9-23) for the procedure on how to
move the windshield wiper blades to
the service position.
 When the vehicle power is switched
ON and the wiper lever is in the
AUTO position, the windshield
wipers may operate automatically in
the following cases:
The area of the windshield above the
rain sensor is touched or wiped with
a cloth.
The windshield or the rain sensor
area in the cabin is hit.
When the vehicle power is switched
ON and the wiper lever is in the
AUTO position, do not touch the
windshield or the windshield wipers
Otherwise, the windshield wipers
will operate automatically which
could catch your fingers or damage
the windshield wipers.
When removing ice or snow, or
cleaning the windshield, always
make sure the wiper lever is in the
OFF position.
 Do not spray water in the engine
compartment. Otherwise, it could
result in engine-starting problems or
damage to electrical parts.
 When washing and waxing the
vehicle, be careful not to apply
excessive force to any single area of
the vehicle roof. Otherwise, you
could dent the vehicle.
 Make sure that the fuel-filler lid is
closed and lock the doors.
Otherwise, the fuel-filler lid may be
forcefully opened by water pressure
causing damage to the vehicle or
fuel-filler lid.
 (Vehicles with hands-free liftgate)
When washing or waxing the vehicle,
turn off the hands-free liftgate using
the Mazda Connect or do not bring
the transmitter into the area around
the liftgate. Otherwise, the liftgate
could open unexpectedly resulting in
an accident. Refer to Power Liftgate
section (page 4-21).
 Do not use steel wool, abrasive
cleaners, or strong detergents
containing highly alkaline or caustic
agents on chrome-plated or
anodized aluminum parts. This may
damage the protective coating; also,
cleaners and detergents may discolor
or deteriorate the paint.

Glossary of Terms
Tire Placard: A label indicating the OE
tire sizes, recommended inflation
pressure, and the maximum weight the

providing information about the tire
brand and manufacturing plant, tire
size, and date of manufacture.
Inflation Pressure:
A measure of the
amount of air in a tire.
kPa: Kilopascal, the metric unit for air
pressure.
psi: Pounds per square inch, the
English unit for air pressure.
B-pillar: The structural member at the
side of the vehicle behind the front
door.
Original Equipment (OE): Describes
components originally equipped on
the vehicle.
Vehicle Load Limit: The maximum
value of the combination weight of
occupants and cargo.
Bead Area of the Tire: Area of the tire

Ve h i c l e L o a d i n g
This section will guide you in the proper loading of your vehicle and/or trailer, to
keep your loaded vehicle weight within its design rating capability, with or without a
trailer. Properly loading your vehicle will provide maximum return of vehicle design
performance. Before loading your vehicle, familiarize yourself with the following
terms for determining your vehicle's weight ratings, with or without a trailer, from
the vehicle's Safety Certification Label and Tire and Load Information Label:
WARNING
Overloaded Vehicle.
Overloading a vehicle is dangerous. The results of overloading can have serious
consequences in terms of passenger sa fety. Too much weight on a vehicle's
suspension system can cause spring or shoc k absorber failure, brake failure, handling
or steering problems, irregular tire wear, tire failure or other damage.
Overloading makes a vehicle harder to drive and control. It also increases the
distance required for stopping. In cases of serious overloading , brakes can fail
completely, particularly on steep grades. The load a tire will carry safely is a
combination of the size of the tire, its load range, and corresponding inflation
pressure.
Never overload the vehicle and always observe the vehicle's weight ratings from the
vehicle's Safety Certification and Tire and Load Information labels.
Base Curb Weight is the weight of the ve hicle including a full tank of fuel and all
standard equipment. It does not include passengers, cargo, or optional
equipment.

Ve h i c l e C u r b We i g h t is the weight of your new vehicle when you picked it up from
your dealer plus any aftermarket equipment.

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

GCWR (Gross Combination Weight Rating) is the maximum allowable weight of
the vehicle and the loaded trailer - incl uding all cargo and passengers - that the
vehicle can handle without risking damage. (Important: The towing vehicle's braking
system is rated for operation at GVWR, not at GCWR. Separate functional brakes
should be used for safe control of towed vehicles and for trailers weighing more than
1,500 lbs). The GCW must never exceed the GCWR.

Maximum Loaded Trailer Weight is the highest possible weight of a fully loaded
trailer the vehicle can tow. It assumes a vehicle with only mandatory options, no
cargo (internal or external), a tongue load of 10 －15% (conventional trailer) or king
pin weight of 15 －25% (fifth-wheel trailer), and driver only (150 lbs). Consult your
dealership (or the RV and Trailer Towing Guide provided by your dealership) for
more detailed information.
Tongue Load or Fifth-Wheel King Pin Weight refers to the amount of the weight that
a trailer pushes down on a trailer hitch.

Examples: For a 5000 lb conventional trailer, multiply 5000 by 0.10 and 0.15 to
obtain a proper tongue load range of 500 to 750 lbs. For an 11,500 lb fifth-wheel
trailer, multiply by 0.15 and 0.25 to obt ain a proper king pin load range of 1,725 to
2,875 lbs.
WARNING
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 lo ad carrying capacities than the originals
because they may lower the vehicle's GVWR and GAWR limitations. Replacement
tires with a higher limit than the orig inals do not increase the GVWR and GAWR
limitations.
Never exceed the GVWR or the GAWR specified on the certification label.
