Modification and Add-OnEquipment
Mazda cannot guarantee the immobilizer
and the theft-deterrent systems' operation
if the system has been modified or if any
add-on equipment has been installed.
CAUTION
To avoid damage to the vehicle, do not
modify the system or install any add-on
equipment to the immobilizer and the
theft-deterrent systems or the vehicle.
Immobilizer System
The 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
vehicle theft.
If you have a problem with the
immobilizer system or the key, consult an
Authorized Mazda Dealer.
CAUTION
Radio equipment like this is governed by
laws in the United States.
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.
 If the engine does not start with the
correct key, and the security indicator
light keeps illuminating or flashing, the
system may have a malfunction. Consult
an Authorized Mazda Dealer.

NOTE
ï‚·The keys carry a unique electronic code.
For this reason, and to assure your
safety, obtaining a replacement key
requires some waiting time. They are
only available through an Authorized
Mazda Dealer.
ï‚·Always keep a spare key in case one is
lost. If a key is lost, consult an
Authorized Mazda Dealer as soon as
possible.
ï‚·If you lose a key, an Authorized Mazda
Dealer, will reset the electronic codes of
your remaining keys and immobilizer
system. Bring all the remaining keys to
the Authorized Mazda Dealer to reset.
Starting the vehicle with a key that has
not been reset is not possible.
â–¼ Operation
NOTE
ï‚·The engine may not start and security
indicator light may illuminate or flash if
the key is placed in an area where it is
difficult for the system to detect the
signal, such as on the dashboard or in
the glove compartment. Move the key to
a location within the signal range,
switch the ignition off, and then restart
the engine.
ï‚·Signals from a TV or radio station, or
from a transceiver or mobile telephone
could interfere with your immobilizer
system. If you are using the proper key
and the engine fails to start, check the
security indicator light.
Arming
The system is armed when the ignition is
switched from ON to off.
The security indicator light in the
instrument cluster flashes every 2 seconds
until the system is disarmed.
Disarming
The system is disarmed when the ignition
is switched ON with the correct
programmed key. The security indicator
light illuminates for about 3 seconds and
then turns off. If the engine does not start
with the correct key, and the security
indicator light remains illuminated or
flashing, try the following:
Make sure the key is within the
operational range for signal transmission.
Switch the ignition off, and then restart the
engine. If the engine does not start after 3
or more tries, contact an Authorized
Mazda Dealer.
NOTE
ï‚·If the security indicator light flashes
continuously while you are driving, do
not shut off the engine. Go to an
Authorized Mazda Dealer, and have it
checked. If the engine is shut off while
the indicator light is flashing, you will
not be able to restart it.
ï‚·Because the electronic codes are reset
when the immobilizer system is repaired,
the keys are needed. Make sure to bring
all the keys to an Authorized Mazda
Dealer, so that they can be programmed.

Floor Mat
We recommend the use of Genuine
Mazda floor mats.
WA R N I N G
Make sure the floor mats are hooked on the
retention pins to prevent them from
bunching up under the foot pedals:
Using a floor mat that is not secured is
dangerous as it will interfere with the
accelerator and brake pedal operation,
which could result in an accident.
Do not install two floor mats, one on top of
the other, on the driver's side:
Installing two floor mats, one on top of the
other, on the driver's side is dangerous as
the retention pins can only keep one floor
mat from sliding forward.
Loose floor mat(s) will interfere with the
foot pedals and could result in an accident.
If using an all-weather mat for winter use
always remove the original floor mat.
When setting a floor mat, position the
floor mat so that its grommets are inserted
over the pointed end of the retention posts.
Rocking the Vehicle
WA R N I N G
Do not spin the wheels at more than 56
km/h (35 mph), and do not allow anyone
to stand behind a wheel when pushing the
vehicle:
When the vehicle is stuck, spinning the
wheels at high speed is dangerous. The
spinning tire could overheat and explode.
This could cause serious injuries.
CAUTION
Too much rocking may cause engine
overheating, transaxle failure, and tire
damage.
If you must rock the vehicle to free it from
snow, sand or mud, depress the accelerator
slightly and slowly move the selector lever
from D to R position.

WA R N I N G
Use only the same size and type tires (snow,
radial, or non-radial) on all 4 wheels:
Using tires different in size or type is
dangerous. Your vehicle's handling could
be greatly affected and result in an
accident.
CAUTION
Check local regulations before using
studded tires.
NOTE
If your vehicle is equipped with the tire
pressure monitoring system, the system
may not function correctly when using
tires with steel wire reinforcement in the
sidewalls (page 4-257).
â–¼ Tire Chains
Check local regulations before using tire
chains.
CAUTION

Chains may affect handling.
 Do not 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.
 Do not use chains on a temporary spare
tire; it may result in damage to the
vehicle and to the tire.
 Do not use chains on roads that are free
of snow or ice. The tires and chains could
be damaged.
Chains may scratch or chip aluminum
wheels.
NOTE
ï‚·If your vehicle is equipped with the tire
pressure monitoring system, the system
may not function correctly when using
tire chains.
Install the chains on the front tires only.
Do not use chains on the rear tires.
Please consult an Authorized Mazda
Dealer.
Installing the chains

When not towing a trailer, remove the trailer hitch (if detachable) to reduce the possibility of
damage as a result of the vehicle being rear-ended.
WARNING
Always make sure the trailer hitch is securely attached before departure:
An unsecured trailer hitch is dangerous as it causes greater trailer sway from crosswinds,
rough roads or other causes, resulting in loss of control and a serious accident.
Examine all trailer-hitch mounting bolts regularly and tighten any that are loose. If the hitch
is removed, seal any open mounting holes to prevent exhaust, dust, water, dirt and other
foreign elements from filtering in, possibly en dangering personal safety and damaging your
vehicle.
Do not install a hitch that stiffens the bumper as it will reduce the bumper's performance.
Make sure there are no exhaust gas leaks into the passenger compartment if any mounting
bolts are connected to the body:
Modifying your vehicle exhaust system is dangerous. Exhaust gas entering the vehicle could
cause loss of consciousness or even death.
When mounting the trailer hitch, make no modifications to the vehicle exhaust system.
CAUTION
 Make all hitch adjustments with actual load s. Do not load and unload vehicle while
adjusting hitch. This action w ill change the vehicle height.
 Do not use an axle-mounted hitch. This may damage the axle and related parts.
â–¼ Tires
When towing a trailer, make sure all tires
are inflated to the recommended cold-tire
pressure, as indicated on the tire pressure chart on the driver's door frame. Trailer tire size,
load rating, and inflation pres sures should conform to tire manufacturer specifications.
WARNING
Never use the temporary spare tire when towing:
Using the temporary spare tire on your vehicle wh en towing a trailer is dangerous as it could
result in tire failure, loss of control, and injury to vehicle occupants.
â–¼ Safety Chains
Safety chains must be used as a precautionary measure should the trailer become
unintentionally unhitched. They should cross under the trailer tongue and attach to the hitch.

Leave enough slack to allow full turns. Consult literature published by your trailer or hitch
manufacturer for more details.
WA R N I N G
Make sure the safety chain is securely attached to both the trailer and the vehicle prior to
departure:
Towing a trailer without using a safety chain securely attached to both the trailer and the
vehicle is dangerous. If damage occurs to the coupling unit or hitch ball, the trailer could
wander into another lane and cause a collision.
â–¼ Trailer Lights
Trailer lights must comply with all federal, st
ate, and local regulations. Equip your trailer as
required before towing it day or night.
CAUTION
Do not connect a trailer lighting system directl y to the lighting system of your Mazda. This
may damage your vehicle's electrical system an d lighting systems. Have a recreational vehicle
dealer or trailer rental agency connect the system, and inspect the brake lights and turn
signals yourself before each trip.
â–¼ Trailer Brakes
If the total trailer weight exceeds 450 kg (1,000
lb), trailer brakes are required. If your trailer
has brakes, make sure they comply with all federal, state, and local regulations.
WA R N I N G
Do not connect a hydraulic trailer-brake system to your vehicle's brake system:
Connecting a hydraulic trailer-brake system direc tly to the vehicle brake system is dangerous
and will result in inadequate braking and possible injury.
â–¼ Trailer Towing Tips
ï‚·Verify that your Mazda maintains a near-normal attitude when a loaded or unloaded trailer
is connected. Do not drive if it has an abnor
mal front-up or front-down position. Inspect
for incorrect tongue load, worn suspension parts, and trailer overloading.
ï‚·Make sure the trailer is properly loaded and th e cargo is secure to prevent it from shifting.
ï‚·Make sure the mirrors conform to all government regulations. If they do not, install
required rear view mirrors appropriate for towing purposes.
