í
qInspecting Automatic Transaxle
Fluid Level
The automatic transaxle fluid level should
be inspected regularly. Measure it as
described below.
5AT
CAUTION
lAlways check the automatic
transaxle fluid level according to the
following procedure. If the
procedure is not done correctly, the
automatic transaxle fluid level
cannot be measured accurately
which could lead to automatic
transaxle damage.
lA low fluid level can cause transaxle
slippage. Overfilling can cause
foaming, loss of fluid, and transaxle
malfunction.
lUse only the specified fluid. A non-
specified fluid could result in
transaxle malfunction and failure.
1. Park on a level surface and set the
parking brake firmly.
2. Make sure there is no ATF leakage
from the ATF hose or the housing.
3. Shift the shift lever to the park position
(P), start the engine and warm it up.

WARNING
Do not replace the xenon fusion bulbs
yourself:
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. 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 Exterior Light Bulbs
Replacing a headlight bulb
(Without turbocharger)
1. Make sure the ignition switch is turned
off and the headlight switch is off.
2. Lift the hood.
3. Turn the screws counterclockwise and
remove them and the cover when
replacing the left headlight bulb.
Cover
4. 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 8-41.
(With turbocharger)
1. Make sure the ignition switch is turned
off and the headlight switch is off.
