WARNING
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.



WARNING
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.

Nut tightening torque
N·m (kgf·m, ft·lbf) 108—147 (12—14, 80—108)

WARNING
Always securely and correctly tighten
the lug nuts:
Improperly or loosely tightened lug
nuts are dangerous. The wheel could
wobble or come off . This could result
in loss of vehicle control and cause a
serious accident.

Be sure to reinstall the same nuts you
removed or replace them with metric
nuts of the same confi guration:
Because the wheel studs and lug nuts
on your Mazda have metric threads,
using a non-metric nut is dangerous.
On a metric stud, it would not secure
the wheel and would damage the stud,
which could cause the wheel to slip off
and cause an accident.

Warning/Indicator Lights and Warning Sounds
Contact Authorized Mazda Dealer and Have Vehicle Inspected
If any of the following warning lights or the indicator light turns on/À ashes, the system may
have a malfunction. Contact an Authorized Mazda Dealer to have your vehicle inspected.

Signal Warning


Master Warning
Light (Vehicles with type B audio)
The light turns on when the system has a malfunction.
Operate the center display and verify the content.
Refer to If a Warning Light Turns On or Flashes on page 7-27 .
(Vehicles without type B audio)
The light illuminates continuously if any one of the following occurs. Consult an
Authorized Mazda Dealer.
y There is a malfunction in the battery management system.
y There is a malfunction in the brake switch.


ABS Warning Light If the ABS warning light stays on while you're driving, the ABS control unit has detected a
system malfunction. If this occurs, your brakes will function normally as if the vehicle had
no ABS.
Should this happen, consult an Authorized Mazda Dealer as soon as possible. N O T E
y When the engine is jump-started to charge the battery, uneven rpm occurs and the ABS
warning light may illuminate. If this occurs, it is the result of the weak battery and does not
indicate an ABS malfunction.
Recharge the battery.
y The brake assist system does not operate while the ABS warning light is illuminated.


Check Engine Light If this light illuminates while driving, the vehicle may have a problem. It is important to
note the driving conditions when the light illuminated and consult an Authorized Mazda
Dealer.
The check engine light may illuminate in the following cases:
y The fuel tank level being very low or approaching empty.
y The engine's electrical system has a problem.
y The emission control system has a problem.
y The fuel-¿ ller cap is missing or not tightened securely.
If the check engine light remains on, or it À ashes continuously , do not drive at high speeds
and consult an Authorized Mazda Dealer as soon as possible.


Automatic
Transaxle Warning
Light The light illuminates when the transaxle has a problem. CAUTION
If the automatic transaxle warning light illuminates, the transaxle has an electrical

*Some models.
Signal Warning Action to be taken


Door-Ajar
Warning Light The light turns on if any door is not closed
securely. Close the door securely.

Low Washer
Fluid Level
Warning Light
* This warning light indicates that little washer À uid
remains. Add washer À uid (page 6-32 ).

(Illuminate)
Tire Pressure
Monitoring
System Warning
Light
* When the warning light illuminates, and the
warning beep sound is heard (about 3 seconds),
tire pressure is too low in one or more tires.
WARNING
If the tire pressure monitoring system warning
light illuminates or fl ashes, 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 illuminates or fl ashes, 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
fl at, 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
dangerous, 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. Inspect the tires and adjust to the
speci¿ ed inÀ ation pressure (page 6-42 ).
N O T E
y Perform 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 inÀ ation pressure, the TPMS
warning light/beep may turn on after
the tires cool and pressure drops below
speci¿ cation.
Also, an illuminated TPMS warning
light, resulting from the tire air
pressure dropping due to cold ambient
temperature will remain illuminated
even 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.
y Tires lose air naturally over time and
the TPMS cannot tell if the tires are
getting too soft over time or you have
a À at. However, when you ¿ nd 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 reinÀ ating the tire
as leaks are dangerous — take it to an
Authorized Mazda Dealer.
