minerals will concentrate and harden to
form white rings. The rings can damage
your vehicle's finish.
Prevention
It is necessary to wash and wax your
vehicle to preserve its finish according to
the instructions in this section. These steps
should be taken immediately after you find
water marks on your vehicle's finish.
Paint Chipping
Occurrence
Paint chipping occurs when gravel thrown
in the air by another vehicle's tires hits
your vehicle.
How to avoid paint chipping
Keeping a safe distance between you and
the vehicle ahead reduces the chances of
having your paint chipped by flying
gravel.
NOTE
The paint chipping zone varies with the
speed of the vehicle. For example, when
traveling at 90 km/h (56 mph), the paint
chipping zone is 50 m (164 ft).
In low temperatures a vehicle's finish
hardens. This increases the chance of
paint chipping.
Chipped paint can lead to rust forming
on your Mazda. Before this happens,
repair the damage by using Mazda
touch-up paint according to the
instructions in this section. Failure to
repair the affected area could lead to
serious rusting and expensive repairs.

Follow all label and container directions
when using a chemical cleaner or polish.
Read all warnings and cautions.
▼ Maintaining the Finish
Wa s h i n g
CAUTION

When the wiper lever is in the AUTO
position and the ignition is switched ON,
the wipers may move automatically in
the following cases:
 If the windshield above the rain sensor
is touched or wiped with a cloth.
 If the windshield is struck with a hand
or other object from either outside or
inside the vehicle.
Keep hands and scrapers clear of the
windshield when the wiper lever is in the
AUTO position and the ignition is
switched ON as fingers could be pinched
or the wipers and wiper blades damaged
when the wipers activate automatically.
If you are going to clean the windshield,
be sure the wipers are turned off
completely (when it is most likely that the
engine is left running) this is particularly
important when clearing ice and snow.

Make sure the moving parts are kept
free from dirt or rust.
Make sure the screw thread is
adequately lubricated.
▼Spare Tire
Your Mazda has a temporary spare tire.
The temporary spare tire is lighter and
smaller than a conventional tire, and is
designed only for emergency use and
should be used only for VERY short
periods. Temporary spare tires should
NEVER be used for long drives or
extended periods.
WA R N I N G
Do not install the temporary spare tire on
the front wheels (driving wheels):
Driving with the temporary spare tire on
one of the front driving wheels is
dangerous. Handling will be affected. You
could lose control of the vehicle, especially
on ice or snow bound roads, and have an
accident. Move a regular tire to the front
wheel and install the temporary spare tire
to the rear.
CAUTION

When using the temporary spare tire,
driving stability may decrease compared
to when using only the conventional tire.
Drive carefully.
 To avoid damage to the temporary spare
tire or to the vehicle, observe the
following precautions:
 Do not exceed 80 km/h (50 mph).
Avoid driving over obstacles. Also, do
not drive through an automatic car
wash. This tire's diameter is smaller
than a conventional tire, so the ground
clearance is reduced.
 Do not use a tire chain on this tire
because it will not fit properly.
 Do not use your temporary spare tire
on any other vehicle, it has been
designed only for your Mazda.
 Use only one temporary spare tire on
your vehicle at the same time.
To remove the spare tire

Make sure the mounting surfaces of the
wheel, hub and lug nuts are clean
before changing or replacing tires:
When changing or replacing a tire, not
removing dirt and grime from the
mounting surfaces of the wheel, hub
and hub bolts is dangerous. The lug
nuts could loosen while driving and
cause the tire to come off, resulting in
an accident.
2. Mount the spare tire.
3. Install the lug nuts with the beveled edge inward; tighten them by hand.

WA R N I N G
Do not apply oil or grease to lug nuts
and bolts and do not tighten the lug
nuts beyond the recommended
tightening torque:
Applying oil or grease to lug nuts and
bolts is dangerous. The lug nuts could
loosen while driving and cause the tire
to come off, resulting in an accident. In
addition, lug nuts and bolts could be
damaged if tightened more than
necessary.
4. Turn the lug wrench counterclockwise and lower the vehicle.
5. Use the lug wrench to tighten the nuts in the order shown.

If you are unsure of how tight the nuts
should be, have them inspected at an
Authorized Mazda Dealer.

CAUTION
Tuck a cloth between the flat tire and
the vehicle trim. If the flat tire directly
contacts the vehicle trim, the trim may
be damaged.
9. Slowly close the liftgate while making sure that the liftgate trim does not
contact the flat tire.
NOTE
If the liftgate trim contacts the flat tire,
adjust the position of the flat tire.
10. Make sure that the liftgate closes
securely.
11. Check the tire inflation pressure. Refer to the spec ification charts on
page 9-7.
12. Have the flat tire repaired or replaced
as soon as possible.
WA R N I N G
Do not drive with any tires that have
incorrect air pressure:
Driving on tires with incorrect air pressure
is dangerous. Tires with incorrect pressure
could affect handling and result in an
accident. When you check the regular tires'
air pressure, check the spare tire, too.
NOTE
To prevent the jack and tool from rattling,
store them properly.

Wa r n i n g
When the warning light illumina tes, and the warning beep sound is heard when tire pressure is too low in one or
more tires.
WA R N I N G
If the tire pressure monitoring system warning light illuminates or flashes, or the tire pressure warning beep sound
is heard, decrease vehicle speed immediately and avoid sudden maneuvering and braking:
If the tire pressure monitoring system warning light illumin ates or flashes, or the tire pressure warning beep sound
is heard, it is dangerous to drive the vehicle at high speeds, or perform sudden maneuvering or braking. Vehicle
drivability could worsen and result in an accident.
To determine if you have a slow leak or a flat, pull over to a safe position where you can check the visual condition
of the tire and determine if you have enough air to proceed to a place where air may be added and the system
monitored again by an Authorized Mazda Dealer or a tire repair station.
Do not ignore the TPMS Warning Light:
Ignoring the TPMS warning light is da ngerous, even if you know why it is illuminated. Have the problem taken
care of as soon as possible before it develops into a more serious situation that could lead to tire failure and a
dangerous accident.

Action to be taken
Inspect the tires and adjust to the sp ecified inflation pressure (page 6-34).
CAUTION
When replacing/repairing the tires or wheels or both, have the work done by an Authorized Mazda Dealer, or the
tire pressure sens ors may be damaged.
NOTE
Perform tire pressure adjustment when the tires are cold . Tire pressure will vary according to the tire temper‐
ature, therefore let the vehicle stand for 1 hour or only drive it 1.6 km (1 mile) or less before adjusting the
tire pressures. When pressure is adjusted on hot tires to the cold inflation pressure, the TPMS warning light/
beep may turn on after the tires cool and pressure drops below specification.
Also, an illuminated TPMS warning light, resulting from the tire air pressure dropping due to cold ambient
temperature, may turn off if the ambient temperature rises. In this case, it will also be necessary to adjust the
tire air pressures. If the TPMS warnin g light illuminates due to a drop in tire air pressure, make sure to check
and adjust the tire air pressures.
After adjusting the tire air pressures, it may require some time for the TPMS warning light to turn off. If the
TPMS warning light remains illuminate d, drive the vehicle at a speed of at least 25 km/h (16 mph) for 10
minutes, and then verify that it turns off.
Tires lose air naturally over time and the TPMS cannot tell if the tires are getting too soft over time or you
have a flat. However, when you find one low tire in a set of four-that is an indication of trouble; you should
have someone drive the vehicle slowly forward so you can inspect any low tire for cuts and any metal objects
sticking through tread or sidewall. Put a few drops of water in the valve stem to see if it bubbles indicating a
bad valve. Leaks need to be addr essed by more than simply refilling the trouble tire as leaks are dangerous
― take it to an Authorized Mazda Dealer which has all the equipment to fix tires, TPMS systems and order
the best replacement tire for your vehicle.
If the warning light illuminates again even after the tire pressures are adjusted, there may be a tire puncture.

Uniform Tire Quality Grading System (UTQGS)
This information relates to the tire grading system developed by the U.S. National Highway
Traffic Safety Administration for grading t ires by tread wear, traction, and temperature
performance.
▼ Tr e a d We a r
The tread wear grade is a comparative rating based on the wear rate of the tire when tested
under controlled conditions on a
specified government test course.
For example, a tire graded 150 would wear on e-and-a-half times as well on the government
course as a tire graded 100.

The relative performance of tires depends upon the actual conditions of their use, however,
and may depart significantly from the norm because of variations in driving habits, service
practices and differences in road characteristics and climate.
▼ Traction-AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B, and C. These grades represent the
tire's ability to stop on wet pavement as meas
ured under controlled conditions on specified
government test surfaces of asphalt and conc rete. A tire marked C may have poor traction
performance.
WARNING
The traction grade assigned to this tire is based on braking (straight ahead) traction tests and
does not include acceleration cornering (turning), hydroplaning, or peak traction
characteristics.
▼ Te m p e r a t u r e - A , B , C
The temperature grades A (the highest), B, and C, represent the tire's resistance to the
generation of heat and its abili
ty to dissipate heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire
life, and excessive temperatures can lead to sudden tire failure.

Grade C corresponds to a level of performance which all passenger vehicle tires must meet
under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher
levels of performance on the laboratory test wheel than the minimum required by law.

WA R N I N G
Keep your vehicle's tires properly inflated and not overloaded:
Driving with improperly inflated or overl oaded tires is dangerous. Excessive speed,
underinflation, or excessive loading, either separately or in combination, can cause heat
buildup and possible tire failure. The temperatur e grade for this tire is established for a tire
that is properly inflated and not overloaded.

These grades will be added to the sidewalls of passenger vehicle tires over the next several
years according to a schedule established by the NHTSA and the tire manufacturers.

The grade of tires available as standard or optional equipment on Mazda vehicles may vary
with respect to grade.

ALL PASSENGER VEHICLE TIRES MUST CONFORM TO THESE GRADES AND TO
ALL OTHER FEDERAL TIRE-SAFETY REQUIREMENTS.
▼ UNIFORM TIRE QUALITY GRADING
Quality grades can be found where applicable on the tire sidewall between tread shoulder
and maximum section width.
