Use only a Mazda-genuine tire valve
cap:
Use of a non-genuine part is
dangerous as the correct tire air
pressure cannot be maintained if the
tire valve becomes damaged. If the
vehicle is driven under this condition,
the tire air pressure will decrease
which could result in a serious
accident. Do not use any part for the
tire valve cap that is not a
Mazda-genuine part.
Inspect all tire pressures monthly
(including the spare) when the tires are
cold. Maintain recommended
pressures for the best ride, handling ,
and minimum tire wear.
Refer to the specification charts (page
9-7).
NOTE
Always check tire pressure when tires
are cold.
Warm tires normally exceed
recommended pressures. Do not
release air from warm tires to adjust
the pressure.
Underinflation can cause reduced
fuel economy, uneven and
accelerated tire wear, and poor
sealing of the tire bead, which will
deform the wheel and cause
separation of tire from rim.
Overinflation can produce a harsh
ride, uneven and accelerated tire
wear, and a greater possibility of
damage from road hazards.
Keep your tire pressure at the correct
levels. If one frequently needs
inflating, have it inspected.
▼ Tire Rotation
WARNING
Rotate tires periodically:
Irregular tire wear is dangerous. To
equalize tread wear for maintaining
good performance in handling and
braking, rotate the tires periodically or
sooner if irregular wear develops.
Please refer to Scheduled maintenance
for your tire rotation interval.
During rotation, inspect them for
correct balance.
1. Forward
Do not include (TEMPORARY USE
ONLY) spare tire in rotation.
Also, inspect them for uneven wear
and damage. Abnormal wear is usually
caused by one or a combination of the
following:
Incorrect tire pressureImproper wheel alignmentOut-of-balance wheelSevere braking
After rotation, inflate all tire pressures
to specification (page 9-7) and
inspect the lug nuts for tightness.

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 or the antenna.
Otherwise, you could dent the
vehicle or damage the antenna.
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.
To help protect the finish from rust and
deterioration, wash your Mazda
thoroughly and frequently, at least
once a month, with lukewarm or cold
water.
If the vehicle is washed improperly, the
paint surface could be scratched. Here
are some examples of how scratching
could occur.
Scratches occur on the paint surface
when:
The vehicle is washed without first
rinsing off dirt and other foreign
matter.
The vehicle is washed with a rough,
dry, or dirty cloth.
The vehicle is washed at a car wash
that uses brushes that are dirty or too stiff.
Cleansers or wax containing
abrasives are used.
NOTE
Mazda is not responsible for
scratches caused by automatic car
washes or improper washing.
Scratches are more noticeable on
vehicles with darker paint finishes.
To minimize scratches on the vehicle's
paint finish:
Rinse off any dirt or other foreign
matter using lukewarm or cold water
before washing.
Use plenty of lukewarm or cold
water and a soft cloth when washing
the vehicle. Do not use a nylon cloth.
Rub gently when washing or drying
the vehicle.
Take your vehicle only to a car wash
that keeps its brushes well
maintained.
Do not use abrasive cleansers or wax
that contain abrasives.
CAUTION
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.
Pay special attention to removing salt,
dirt, mud, and other foreign material
from the underside of the fenders, and
make sure the drain holes in the lower
edges of the doors and rocker panels
are clean.
Insects, tar, tree sap, bird droppings,
industrial fallout, and similar deposits
can damage the finish if not removed
immediately. When prompt washing

WARNING
Do not tow a trailer with this vehicle:
Towing a trailer with this vehicle is
dangerous because it has not been
designed to tow a trailer and doing so
will
affect the drive system which could
result in vehicle damage.
This section will guide you in the
proper loading of your vehicle, to keep
your loaded vehicle weight within its
design rating capability. 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, 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 safety. Too much weight on
a vehicle's suspension system can
cause spring or shock 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
vehicle including a full tank of fuel
and all standard equipment. It does
not include passengers, cargo, or
optional equipment.
Vehicle Curb Weight is the weight of
your new vehicle when you picked it
up from your dealer plus any
aftermarket equipment.
PAY LOA D
Pay l o a d is the combination weight of
cargo and passengers that the vehicle
is designed to carry. The maximum
payload for your vehicle can be found
on the Tire and Load Information label
on the driver's door frame or door
pillar. Look for “THE COMBINATION
WEIGHT OF OCCUPANTS AND
CARGO SHOULD NEVER EXCEED XXX
kg or XXX lbs” for your maximum
payload. The payload listed on the tire
label is the maximum payload for the
vehicle as built by the assembly plant.
If any aftermarket or dealer installed
equipment has been installed on the
vehicle, the weight of the equipment
must be subtracted from the payload
