qReplacing a Wheel
WARNING
Using a Wrong-Sized Wheel:
Using a wrong-sized wheel is
dangerous. Braking and handling
could be affected, leading to loss of
control and an accident. Always use
wheels of the correct size on your
vehicle.
CAUTION
lA wrong-sized wheel may adversely
affect:
lTire fitlWheel and bearing lifelGround clearancelSnow-chain clearancelSpeedometer calibrationlHeadlight aimlBumper heightlTire Pressure Monitoring SystemlLimited-Slip Differential System
l(With Tire Pressure Monitoring
System)
lWhen 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.
lThe wheels equipped on your
Mazda are specially designed for
installation of the tire pressure
sensors. Do not use non-genuine
wheels, otherwise it may not be
possible to install the tire pressure
sensors.
NOTE
Be sure to install the tire pressure
sensors whenever tires or wheels are
replaced. Refer to Tires and Wheels on
page 5-30.
When replacing a wheel, make sure the
new one is the same as the original factory
wheel in diameter, rim width, and offset.
Proper tire balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tires can cause
vibration and uneven wear, such as
cupping and flat spots.

WARNING
Xenon Fusion Bulb Replacement:
Replacing 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. Do not replace the xenon
fusion bulbs yourself. Consult an
Authorized Mazda Dealer when the
replacement is necessary.
Handling Halogen Bulbs:
When a halogen bulb breaks, it is
dangerous. These bulbs contain
pressurized gas. If one is broken, it
will explode and serious injuries could
be caused by the flying glass.
If the glass portion is touched with
bare hands, body oil could cause the
bulb to overheat and explode when lit.
Never touch the glass portion of the
bulb with your bare hands and always
wear eye protection when handling or
working around halogen bulbs.
Children and Halogen Bulbs:
Playing with a halogen bulb is
dangerous. Serious injuries could be
caused by dropping a halogen bulb or
breaking it some other way.
Always keep halogen bulbs out of the
reach of children.
qReplacing a Headlight Bulb
1. Make sure the ignition switch is turned
off and the headlight switch is off.
2. Lift the hood and find the high and low
beam bulbs in the rear of the headlight
unit.
The outboard bulb is the LOW beam,
and the inboard one is the HIGH beam.
Refer to Light Bulbs on page 8-32.
3. If you are changing the right headlight
bulb, start the engine, turn the steering
wheel all the way to the right, and turn
off engine. If you are changing the left
headlight bulb, turn the steering wheel
to the left.
4. Turn the center section of the plastic
retainer counterclockwise and remove
the retainers and partially peel back the
mudguard.
