Adjust the tire pressure to the correct tire
pressure. Refer to the specification charts
(page 10-11).
CAUTION
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.NOTE
lPerform tire pressure adjustment when the
tires are cold. Tire pressure will vary
according to the tire temperature, 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 warning
light illuminates due to a drop in tire air
pressure, make sure to check and adjust the
tire air pressures.
lAfter adjusting the tire air pressures, it may
require some time for the TPMS warning
light to turn off. If the TPMS warning light
remains illuminated, drive the vehicle at a
speed of at least 25 km/h (16 mph) for 10
minutes, and then verify that it turns off.
lTires 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
addressed 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.

NOTElThe headlights, other exterior lights and dashboard illumination may not turn off immediately
even if the surrounding area becomes well-lit because the light sensor determines that it is
nighttime if the surrounding area is continuously dark for several minutes such as inside long
tunnels, traffic jams inside tunnels, or in indoor parking lots.
In this case, the light turns off if the light switch is turned to the OFF position.
lThe dashboard illumination can be adjusted by rotating the knob in the instrument cluster. Also,
the day/night mode can be changed by pressing the knob. To adjust the brightness of the
dashboard illumination: Refer to Dashboard Illumination on page 5-45.
lWhen the headlight switch is in the AUTO position and the ignition is switched to ACC or the
ignition is switched off, the headlights, other exterior lights and dashboard illumination will turn
off.
lThe sensitivity of the AUTO lights may be changed by an Authorized Mazda Dealer. Refer to
Personalization Features on page 10-12.
Xenon fusion headlight bulbsí
The low-beam bulbs of the headlights have xenon fusion bulbs that produce a bright white
beam over a wide area.
WARNING
Do not replace the xenon fusion bulbs yourselfReplacing the xenon fusion bulbs yourself is dangerous. Because the xenon fusion
bulbs require high voltage, you could receive an electric shock if the bulbs are
handled incorrectly. Consult an Authorized Mazda Dealer when the replacement is
necessary.
NOTE
If the headlights flicker, or the brightness weakens, the bulb-life may be depleted and a replacement is
necessary. Consult an Authorized Mazda Dealer.

ØWhen the wiper lever is in the
AUTO position and the ignition is
switched ON, the wipers may
move automatically in the
following cases:
ØIf the windshield above the rain
sensor is touched or wiped with
a cloth.
ØIf 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 ―this is
particularly important when
clearing ice and snow ―when it is
most likely that the engine is left
running. NOTE
lSwitching the auto-wiper lever from the
OFF to the AUTO position while driving
activates the windshield wipers once, after
which they operate according to the rainfall
amount.
lThe auto-wiper control may not operate
when the rain sensor temperature is about
_
10 °C (14 °F) or lower, or about 85 °C
(185 °F) or higher.
lIf the windshield is coated with water
repellent, the rain sensor may not be able to
sense the amount of rainfall correctly and
auto-wiper control may not operate
properly.
lIf dirt or foreign matter (Such as ice or
matter containing salt water) adheres to the
windshield above the rain sensor or if the
windshield is iced, it could cause the wipers
to move automatically. However, if the
wipers cannot remove this ice, dirt or
foreign matter, the auto-wiper control will
stop operation. In this case, set the wiper
lever to the low speed position or high
speed position for manual operation, or
remove the ice, dirt or foreign matter by
hand to restore the auto-wiper operation.
lIf the auto-wiper lever is left in the AUTO
position, the wipers could operate
automatically from the effect of strong light
sources, electromagnetic waves, or infrared
light because the rain sensor uses an
optical sensor. It is recommended that the
auto-wiper lever be switched to the OFF
position other than when driving the vehicle
under rainy conditions.

CAUTION
ØWhen using the temporary spare
tire, driving stability may decrease
compared to when using only the
conventional tire. Drive carefully.
Ø To avoid damage to the temporary
spare tire or to the vehicle, observe
the following precautions:
ØDo not exceed 80 km/h (50
mph).
ØAvoid 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 about
10 mm (0.4 in).
ØDo not use a tire chain on this
tire because it will not fit
properly.
ØDo not use your temporary
spare tire on any other vehicle,
it has been designed only for
your Mazda.
ØUse only one temporary spare
tire on your vehicle at the same
time.
Ø (With limited slip differential)
When using the temporary spare
tire on the front axle, replace it
with a standard tire as soon as
possible. The size difference
between the spare and the
standard tire will cause the limited
slip differential to malfunction.
NOTE
(With Tire Pressure Monitoring System)
A tire pressure sensor is not installed to the
temporary spare tire. The warning light will
flash continuously while the temporary spare
tire is being used (page 5-33).
To remove the spare tire
