NOTElAlways check tire pressure when tires are
cold.
lWarm tires normally exceed recommended
pressures. Don't release air from warm tires
to adjust the pressure.
lUnderinflation 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.
lOverinflation 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.
qTire Rotation
To equalize tread wear, rotate the tires if
irregular wear develops. According to the
scheduled maintenance charts.Refer to
Scheduled Maintenance on page 8-3.
During rotation, inspect them for correct
balance.
Do not include (TEMPORARY USE ONLY)
spare tire in rotation.Forward
Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:
lIncorrect tire pressure
lImproper wheel alignmentlOut-of-balance wheellSevere braking
After rotation, inflate all tire pressures to
specification (page 10-8) and inspect the
lug nuts for tightness.
CAUTION
Rotate unidirectional tires and radial
tires that have an asymmetrical tread
pattern or studs only from front to
rear, not from side to side. Tire
performance will be weakened if
rotated from side to side.
qReplacing a Tire
WARNING
Always use tires that are in good
condition:
Driving with worn tires is dangerous.
Reduced braking, steering, and
traction could result in an accident.
CAUTION
(With Tire Pressure Monitoring
System)
When replacing/repairing the tires or
wheels or both, have the work done
by an Authorized Mazda Dealer, or
the tire pressure sensors may be
damaged.

To keep the fabric looking clean and
fresh, take care of it. Otherwise its color
will be affected, it can be stained easily,
and its fire-resistance may be reduced.
CAUTION
Use only recommended cleaners and
procedures. Others may affect
appearance and fire-resistance.
Piano black panelí
The following parts are fitted with panels
that have been treated with a special
coating that resists scratching.
lInstrument panel side garnishlSteering wheel (partial)
When the panel needs to be cleaned, use a
soft cloth to wipe off dirt from the surface.
NOTE
Scratches or nicks on the panels resulting from
the use of a hard brush or cloth may not be
repairable.
qCleaning the Lap/Shoulder Belt
Webbing
Clean the webbing with a mild soap
solution recommended for upholstery or
carpets. Follow instructions. Don't bleach
or dye the webbing; this may weaken it.
After cleaning the belts, thoroughly dry
the belt webbing and make sure there is
no remaining moisture before retracting
them.
WARNING
Have an Authorized Mazda Dealer
replace damaged seat belts
immediately:
Using damaged seat belts is
dangerous. In a collision, damaged
belts cannot provide adequate
protection.
qCleaning the Window Interiors
If the windows become covered with an
oily, greasy, or waxy film, clean them
with glass cleaner. Follow the directions
on the container.
CAUTION
Don't scrape or scratch the inside of
the rear window. You may damage
the rear window defroster grid.

CAUTION
Rotate unidirectional tires and radial tires that have an asymmetrical tread pattern
or studs only from front to rear, not from side to side. Tire performance will be
weakened if rotated from side to side.
(With limited-slip differential)
Don't use the following:
ØTires not of the designated size
ØTires of different sizes or types at the same time
ØTires not sufficiently inflated
If these instructions aren't followed, the rotation of the left and right wheels will be
different and will thus apply a constant load on the limited-slip differential.
This will cause a malfunction.
qReplacing a Tire
WARNING
Always use tires that are in good condition:
Driving with worn tires is dangerous. Reduced braking, steering, and traction could
result in an accident.
If a tire wears evenly, a wear indicator will appear as a solid band across the tread. Replace
the tire when this happens.
New treadTread wear indicator
Worn tread
You should replace it before the band is across the entire tread.
NOTE
Tires degrade over time, even when they are not being used on the road. It is recommended that tires
generally be replaced when they are 6 years or older. Heat caused by hot climates or frequent high
loading conditions can accelerate the aging process. You should replace the spare tire when you
replace the other road tires due to the aging of the spare tire. Regarding the manufacturing week and
year is indicated with 4 digit. Refer to The tire labeling on page 9-22.

Vehicle Loading
WARNING
Do not taw 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 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 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.
