Power window system initialization
procedure
If the battery was disconnected during
vehicle maintenance, or for other reasons
(such as a switch continues to be operated
after the window is fully open/closed), the
window will not fully open and close
automatically. Carry out the following
procedure to resume operation:
1. Switch the ignition ON.
2. Press the switch and fully open thewindow.
3. Pull up the switch to fully close the window and continue holding the
switch for about 2 seconds after the
window fully closes.
Jam-safe window
If a person's hands, head or an object
blocks the window during the auto-
closing operation, the window will stop
and open halfway.
WARNING
Make sure nothing blocks the window
just before it reaches the fully closed
position or while holding up the power
window switch: Blocking the power window just
before it reaches the fully closed
position or while holding up the
power window switch is dangerous.
In this case, the jam-safe function
cannot prevent the window from
closing all the way. If fingers are
caught, serious injuries could occur. NOTE
Depending on driving conditions, a closing
power window could stop and start opening
when the window feels a shock that is similar
to something blocking it.
In the event the jam-safe function activates and
the power window cannot be closed
automatically, pull and hold the switch and the
window will close.
Engine-off power window operation
The power window can be operated for
about 45 seconds after the ignition is
switched from ON to ACC or OFF with
all doors closed. If any door is opened, the
power window will be inoperable.
NOTE
For engine-off operation of the power window,
the switch must be held up firmly throughout
window closure because the auto-closing
function will be inoperable.

Turbocharger Informationí
The turbocharger greatly enhances engine power. Its advanced design provides improved
operation and requires minimum additional maintenance. To get maximum performance
from your turbocharged engine, take note of the following tips:
lThe turbocharged engine is designed for optimal operation with premium unleaded
gasoline (page 4-2). Do not use fuel with a lower octane rating. Extra fuel additives are
NOT recommended.
lChange the engine oil and filter using the turbo engine interval outlined in the
maintenance schedule (for your driving condition).
lUse only the recommended engine oil (page 8-19). Extra oil additives are NOT
recommended.
lAfter driving at freeway speeds or up a long hill, idle the engine at least 30 seconds to
cool the turbo before turning off the engine. Avoid simply shutting the engine off
abruptly after a hard or long drive. Damage to the turbocharger may result.
lDo not race or over-rev the engine when starting. This should not be done with ANY
engine, especially not with one that's turbocharged.
lDo not add any aftermarket devices to alter the engine's ignition timing, fuel delivery, or
turbo boost pressure. This may lead to serious engine damage and may void your
warranty.

CAUTION
ØEach tire, including the spare (if provided), should be checked monthly when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer
on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard or tire inflation
pressure label, you should determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure
monitoring system (TPMS) that illuminates a low tire pressure telltale when one
or more of your tires is significantly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and may affect the vehicle's
handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it
is the driver's responsibility to maintain correct tire pressure, even if under-
inflation has not reached the level to trigger illumination of the TPMS low tire
pressure telltale.
Ø Your vehicle has also been equipped with a TPMS malfunction indicator to
indicate when the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale will flash for approximately
one minute and then remain continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may not be able to
detect or signal low tire pressure as intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
Ø To avoid false readings, the system samples for a little while before indicating a
problem. As a result it will not instantaneously register a rapid tire deflation or
blow out.
NOTE
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.

Operating Tips
qOperating the Climate Control
System
Operate the climate control system with
the engine running.
NOTE
To prevent the battery from being discharged,
do not leave the fan control dial on for a long
period of time with the ignition switched ON
when the engine is not running.
qClearing the Air Inlet
Clear all obstructions such as leaves,
snow and ice from the hood and the air
inlet in the cowl grille to improve the
system efficiency.
qFoggy Windows
The windows may fog up easily in humid
weather. Use the climate control system to
defog the windows.
To help defog the windows, operate the
air conditioner to dehumidify the air.
NOTE
The air conditioner may be used along with the
heater to dehumidify the air.
qParking in Direct Sunlight
If the vehicle has been parked in direct
sunlight during hot weather, open the
windows to let warm air escape, then run
the climate control system.
qNot Using for a Long Period
Run the air conditioner about 10 minutes
at least once a month to keep internal
parts lubricated.
qCheck the Refrigerant before the
Weather Gets Hot
Have the air conditioner checked before
the weather gets hot. Lack of refrigerant
may make the air conditioner less
efficient. Consult an Authorized Mazda
Dealer for refrigerant inspection.
The air conditioner is filled with
HFC134a (R134a), a refrigerant that will
not damage the ozone layer.
If the air conditioner is low on refrigerant
or has a malfunction, consult an
Authorized Mazda Dealer.
qReplacement of the Cabin Air
Filterí
Your vehicle is equipped with an air filter
for the air conditioner. It is necessary to
change the filter periodically as indicated
in scheduled maintenance (page 8-3).
Consult an Authorized Mazda Dealer for
replacement of the cabin air filter.
