Security System
The optional immobilizer system allows
the engine to start only with a key the
system recognizes.
If someone attempts to start the engine
with an unrecognized key, the engine will
not start, thereby helping to prevent the
theft of your vehicle.
Immobilizer System*
•Changes or modifications not
expressly approved by the party
responsible for compliance could
void the user
’s authority to operate
the equipment.
• To avoid damage to the key, do not:

Drop the key.
 Get the key wet.
 Expose the key to any kind of
magnetic field.
 Expose the key to high
temperatures on places such as
the dashboard or hood, under
direct sunlight.
CAUTION
•When starting the engine do not
allow the following, as the engine
may not start due to the electronic
signal from the ignition key not
being transmitted correctly.

A key ring rests on the key grip.
 Metal parts of other keys or
metal objects touch the key grip.
 Spare keys or keys for other
vehicles equipped with an
immobilizer system touch or

Maintenance
If you have a problem with the
immobilizer system or the key, consult an
Authorized Mazda Dealer.

Modification and Add-On
Equipment
Mazda cannot guarantee the immobilizer
system
’s operation if the system has been
modified or if any add-on equipment has
been installed to it.
NOTE
• If the warning light comes on and
stays on when the ignition switch is
turned to the ON position, the
engine will not start.
• Signals from a TV or radio station,
or from a transceiver or a mobile
telephone, could interfere with your
immobilizer system. If you are
using the proper key and your
engine fails to start, check the
warning light. If it is flashing,
remove the ignition key and wait 2
seconds or more, then reinsert it and
try starting the engine again. If it
doesn
’t start after 3 or more tries,
contact an Authorized Mazda
Dealer.
• If the warning light flashes
continuously while you are driving,
don’
t shut off the engine. Go to an
Authorized Mazda Dealer and have
it checked. If you shut off the
engine while the light is flashing
you won ’t be able to restart it.
NOTE
• The keys carry a unique electronic
code. For this reason, and to assure
your safety, replacement keys
require some waiting time to obtain.
They are only available through an
Authorized Mazda Dealer.
• Always keep a replacement key, in
case one is lost. If a key is lost,
contact an Authorized Mazda
Dealer as soon as possible.
• If you lose a key, an Authorized
Mazda Dealer will reset the
electronic codes of your remaining
keys and immobilizer system.
Starting the vehicle with a key that
has not been reset is not possible.
To avoid damage to your vehicle, do
not modify the system or install any
add-on equipment to it.

Before Driving Your Mazda
Driving Tips
Form No. 8S15-EA-03G

Tire Chains
Check local regulations before using tire
chains.
Install the chains on the rear tires.
Don
’t use chains on the front tires.
Use only SAE Class "S" chains, and make
sure they fit.
Installing the chains
1. Remove the wheel covers, or the chain
bands will scratch them.
2. Secure the chains on the rear tires as tightly as possible. Always follow the
chain manufacturer ’s instructions.
3. Retighten the chains after driving 1/2—1 km (1/4 —1/2 mile).
•
Chains may scratch or chip
aluminum wheels. Install tire chains
on steel wheels only.
• Chains may affect handling.
• Don
’t go faster than 50 km/h (30
mph) or the chain manufacturer ’s
recommended limit, whichever is
lower.
• Drive carefully and avoid bumps,
holes, and sharp turns.
• Avoid locked-wheel braking.
• Don
’t use chains on a temporary
spare tire; it may result in damage to
the vehicle and to the tire.
• Don
’t use chains on roads that are
free of snow or ice. The tires and
chains could be damaged.
CAUTION
Driving In Flooded Area
Driving with Wet Brakes:
Driving with wet brakes is dangerous.
Increased stopping distance or the
vehicle pulling to one side when
braking could result in a serious
accident. Light braking will indicate
whether the brakes have been
affected. Dry the brakes by driving
very slowly and applying the brakes
lightly until brake performance
returns to normal.
Make sure water does not enter the
vehicle interior or the engine area. The
vehicle interior could become wet or
the engine could be damaged.

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

ABS Warning Light*
The warning light stays on for a few
seconds when the ignition switch is turned
to the ON position.
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.
ABS Warning Light and Brake
Warning Light on at the Same Time:
Driving when the brake system
warning light and ABS warning light
are on at the same time is dangerous.
When both lights are on, the rear
wheels could lock more quickly in an
emergency stop than under normal
circumstances.
Don ’t drive with both lights on, and
contact an Authorized Mazda Dealer
to have the brakes inspected as soon
as possible.

Changing code number
To change the code number, first cancel
the number. Then set the new number by

System activation
When the power supply is disconnected or
interrupted, the antitheft system is
activated and the unit is rendered

•Three consecutive errors will
activate the antitheft system, and the
audio unit will be completely
inoperable and Err (error) will flash.
When this happens, the unit must be
replaced by an Authorized Mazda
Dealer at the owner
’s expense.
• Do not allow an unauthorized
person to attempt to input a code

Jack
To remove the jack
Turn the wing bolt counterclockwise.
To secure the jack
Perform the removal procedure in reverse.

Spare Tire
Your Mazda has a temporary spare tire.
The temporary spare tire is lighter and
smaller than a conventional tire, and is
designed only for emergency use and
should be used only for VERY short
periods. Temporary spares should
NEVER be used for long drives or
extended periods.
Driving with a Temporary Spare Tire
on Ice or Snow:
Driving with a spare tire on the rear
(driving) wheels on ice or snow is
dangerous. Handling will be affected.
You could lose control of the vehicle
and have an accident. Put the spare
tire on the front axle and move a
regular tire to the rear.

Wing bolt
WARNING
To avoid damage to the temporary
spare or to the vehicle, observe the
following precautions:
•
Don
’t exceed 80 km/h (50 mph).
• Avoid driving over obstacles.
Also, don
’t drive through an
automatic car wash. This tire ’s
diameter is smaller than a
conventional tire ’s, so the ground
clearance is reduced about 25 mm
(1 in).
• Don
’t use a tire chain on this tire
because it won ’t fit properly.
• Don
’t use your temporary spare on
any other vehicle; it has been
designed only for your Mazda.
• Use only one temporary spare tire
on your vehicle at the same time.
(With limited slip differential)
When using the temporary spare tire
on the rear 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.

5. Store the damaged tire in the trunk.Have the damaged tire repaired as soon
as possible.
Loose 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. Always securely and
correctly tighten the lug nuts.
Metric Studs and Lug Nuts:
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. Be sure to
reinstall the same nuts you removed
or replace them with metric nuts of
the same configuration.
Incorrect Tire Air Pressure:
Driving on tires with incorrect air
pressure is dangerous. Tires with
incorrect pressure could affect
handling and result in an accident.
Don ’t drive with any tires that have
incorrect air pressure. When you
check the regular tires ’ air pressure,
check the spare tire, too.
NOTE
To prevent the jack and tool from
rattling, store them properly.
