qOperation
Arming
The system is armed when the ignition
switch is turned from the ON to the ACC
or LOCK position.
The security indicator light in the
instrument cluster flashes every two
seconds until the system is disarmed.
Disarming
The system is disarmed when the ignition

ignition key and wait 2 seconds or more,
then reinsert it and try starting the engine
again. If it does not start after 3 or more
tries, contact an Authorized Mazda Dealer.
lIf 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 you
shut off the engine while the light is
flashing you will not be able to restart it.
lSince the electronic codes are reset when
repairing the immobilizer system, the keys
are needed. Bring all the existing keys to an
Authorized Mazda Dealer.
qModification 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.
CAUTION
To avoid damage to your vehicle, do

Hazardous Driving
WARNING
Be extremely careful if it is necessary to
downshift on slippery surfaces:
Downshifting into lower gear while
driving on slippery surfaces is
dangerous. The sudden change in tire
speed could cause the tires to skid.
This could lead to loss of vehicle
control and an accident.
Do not rely on ABS as a substitute for
safe driving:
The ABS cannot compensate for
unsafe and reckless driving, excessive
speed, tailgating (following another
vehicle too closely), driving on ice and
snow, and hydroplaning (reduced tire
friction and road contact because of
water on the road surface). You can
still have an accident.
When driving on ice or in water, snow,
mud, sand, or similar hazards:
lBe cautious and allow extra distance
for braking.
lAvoid sudden braking and sudden
maneuvering.
lDo not pump the brakes. Continue to
press down on the brake pedal.
Refer to Anti-Lock Brake System
(ABS) on page 5-7.
lIf you get stuck, select a lower gear and
accelerate slowly. Do not spin the front
wheels.
lFor more traction in starting on
slippery surfaces such as ice or packed
snow, use sand, rock salt, chains,
carpeting, or other nonslip material
under the front wheels.
NOTE
Use snow chains only on the front wheels.
Floor Mat
WARNING
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.
In using a heavy duty floor mat for
winter use always remove the
original floor mat.
Loose floor mat(s) will interfere with
the foot pedal and could result in an
accident.
When setting a floor mat, position the
floor mat so that its eyelets are inserted
over the pointed end of the retention
posts.

qSnow Tires
Use snow tires on all four wheels
Do not go faster than 120 km/h (75 mph)
while driving with snow tires. Inflate
snow tires 30 kPa (0.3 kgf/cm
2, 4.3 psi)
more than recommended on the tire
pressure label (driver's door frame), but
never more than the maximum cold-tire
pressure shown on the tires.
Your vehicle is originally equipped with
all season radials designed to be used all
year around. In some extreme climates
you may find it necessary to replace them
with snow tires during the winter months
to further improve traction on snow and
ice covered roads.
WARNING
Use only the same size and type tires
(snow, radial, or non-radial) on all four
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
5-32).
qTire Chains
Check local regulations before using tire
chains.
CAUTION
ØChains may affect handling.
ØDo not go faster than 50 km/h (30
mph) or the chain manufacturer's
recommended limit, whichever is
lower.
ØDrive carefully and avoid bumps,
holes, and sharp turns.
ØAvoid locked-wheel braking.
ØDo not use chains on a temporary
spare tire; it may result in damage
to the vehicle and to the tire.
ØDo not use chains on roads that
are free of snow or ice. The tires
and chains could be damaged.
ØChains may scratch or chip
aluminum wheels.
NOTE
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.
Do not use chains on the rear tires.
Use only genuine Mazda tire chains.
Please consult an Authorized Mazda
Dealer.
Installing the chains
1. Remove the wheel covers, or the chain
bands will scratch them.
2. Secure the chains on the front 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).

WARNING
Remove the key only when the vehicle
is parked:
Removing the key from the ignition
switch while the vehicle is moving is
dangerous. Removing the key allows
the steering wheel to lock. You will
lose steering control and a serious
accident could occur.
Before leaving the driver's seat, always
switch the ignition off, set the parking
brake, and make sure the shift lever is
in P (automatic transaxle) or in 1st gear
or R (manual transaxle):
Leaving the driver's seat without
switching off the ignition, setting the
parking brake, and shifting the shift
lever to P (automatic transaxle) or to
1st gear or R (manual transaxle) is
dangerous. Unexpected vehicle
movement could occur which could
result in an accident.
In addition, if your intention is to
leave the vehicle for even a short
period, it is important to switch the
ignition off, as leaving it in another
position will disable some of the
vehicle's security systems and run the
battery down.
NOTE
If turning the key is difficult, jiggle the steering
wheel from side to side.
Leaving the key in any position but LOCK
position also disables some of the security
features and may run the battery down.
ACC (Accessory)
The steering wheel unlocks and some
electrical accessories will operate.
ON
This is the normal running position after
the engine is started. The warning lights
(except brakes) should be inspected
before the engine is started (page 5-39).
NOTE
When the ignition switch is turned to the ON
position, the sound of the fuel pump motor
operating near the fuel tank can be heard. This
does not indicate an abnormality.
NOTE
(With headlight auto-leveling)
When the ignition switch is turned to the ON
position, the sound of the headlight leveling
motors operating at the front of the engine
compartment can be heard. This does not
indicate an abnormality.
START
The engine is started in this position. It
will crank until you release the key; then
it returns to the ON position. The brake
warning light can be checked after the
engine is started (page 5-39).
qIgnition Key Reminder
If the ignition is switched to off (LOCK)
or ACC with the key inserted, a
continuous beep sound will be heard
when the driver's door is opened.
NOTE
A personalized function is available to change
the sound volume for the ignition key reminder.
Refer to Personalization Features on page
10-9.
