Supplemental Restraint Systems (SRS) Precautions
The supplemental restraint systems (SRS) include up to 2 air bags (verify“SRS AIRBAG ”
location indicator marks).
They are located in:
lThe steering wheel hub (driver air bag)
lThe passenger dashboard (front passenger air bag)
The air bag supplemental restraint systems are designed to provide supplemental protection
only in the front seats in certain situations, so seat belts are always important in the
following ways:
Without seat belt usage, the air bags cannot provide adequate protection during an accident.
Seat belt usage is necessary to:
lKeep the occupant from being thrown into an inflating air bag.
lReduce the possibility of injuries during an accident that is not designed for air bag
inflation, such as roll-over or rear impact.
lReduce the possibility of injuries in frontal collisions that are not severe enough to
activate the air bags.
lReduce the possibility of being thrown from your vehicle.
lReduce the possibility of injuries to lower body and legs during an accident because the
air bags provide no protection to these parts of the body.
lHold the driver in a position which allows better control of the vehicle.
Children should be protected by a child-restraint system. Laws vary on the size a child
must be to use a child-restraint system (page 2-13).
We have provided a deactivation switch that will disable passenger air bag inflation. Do not
switch off the passenger air bag without reading the “Passenger Air Bag Deactivation
Switch ”(page 2-23).
Carefully consider which child-restraint system is necessary for your child and follow the
installation directions in this Owner's Manual as well as the child-restraint system
manufacturer's instructions.
Please be aware that there is no good way to anchor an upper tether, so do not pick a child
restraint system that uses upper tethers at all.

Winter Driving
lCarry emergency gear, including tire
chains, window scraper, flares, a small
shovel, jumper cables, and a small bag
of sand or salt.
Ask an Authorized Mazda Dealer to
perform the following precautions:
lHave the proper ratio of antifreeze in
the radiator.
lInspect the battery and its cables. Cold
reduces battery capacity.
lUse only cold-weather engine oil (page
8-15).
lInspect the ignition system for damage
and loose connections.
lUse washer fluid made with
antifreeze ―but don't use engine
coolant antifreeze for washer fluid
(page 8-25).
lDon't use the parking brake in freezing
weather as the parking brake may
freeze. Instead, shift to P with an
automatic transmission and to 1 or R
with a manual transmission. Block the
rear wheels.
q Snow Tires
WARNING
Mixing Tire Types:
Using tires different in size or type is
dangerous. Your vehicle's handling
could be greatly affected and result in
an accident. Use only the same size
and type tires (snow, radial, or non-
radial) on all four wheels.
CAUTION
Check local regulations before using
studded tires.
Use snow tires on all four wheels
Don't 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), but never
more than the maximum cold-tire pressure
shown on the tires.
Your vehicle is originally equipped with
summer tires designed for optimum
traction on wet and dry roads. If your
vehicle is to be used on snow and ice
covered roads, you may find it necessary
to replace the original equipment tires
with snow tires, during the winter months.

qJack
To remove the jack
Turn the wing bolt counterclockwise.
To secure the jack
Perform the removal procedure in reverse.
qSpare 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.
WARNING
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.
CAUTION
To avoid damage to the temporary
spare or to the vehicle, observe the
following precautions:
lDon't exceed 80 km/h (50 mph).
lAvoid 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).
lDon't use a tire chain on this tire
because it won't fit properly.
lDon't use your temporary spare on
any other vehicle; it has been
designed only for your Mazda.
lUse 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.

1. Park on a level surface off the right-of-way and firmly set the parking brake.
2. Put a vehicle with an automatic transmission in Park (P), a manual
transmission in Reverse (R) or 1, and
turn off the engine.
3. Turn on the hazard warning flasher.
4. Have everyone get out of the vehicle and away from the vehicle and traffic.
5. Remove the jack, tool, and spare tire (page 7-3).
6. Block the wheel diagonally opposite the flat tire. When blocking a wheel,
place a block both in front and behind
the tire.
NOTE
When blocking a tire, use rocks or
wood blocks of sufficient size to hold
the tire in place.
qRemoving a Flat Tire
1. Loosen the lug nuts by turning them
counterclockwise one turn each, but
don't remove any lug nuts until the tire
has been raised off the ground.
2. Place the jack under the jacking
position closest to the tire being
changed.

The battery is in the trunk.
qBattery Maintenance
To get the best service from a battery:
lKeep it securely mounted.
lKeep the top clean and dry.
lKeep terminals and connections clean,
tight, and coated with petroleum jelly
or terminal grease.
lRinse off spilled electrolyte
immediately with a solution of water
and baking soda.
lIf the vehicle will not be used for an
extended time, disconnect the battery
cables.
Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inflation pressures and
stay within the recommended load limits
and weight distribution.
WARNING
Using Different Tire Types:
Driving your vehicle with different
types of tires is dangerous. It could
cause poor handling and poor
braking; leading to loss of control.
Except for the limited use of the
temporary spare tire, use only the
same type tires (radial, bias-belted,
bias-type) on all four wheels.
Using Wrong-Sized Tires:
Using any other tire size than what is
specified for your Mazda (page 10-6)
is dangerous. It could seriously affect
ride, handling, ground clearance, tire
clearance, and speedometer
calibration. This could cause you to
have an accident. Use only tires that
are the correct size specified for your
Mazda.

Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:
lIncorrect tire pressure
lImproper wheel alignment
lOut-of-balance wheel
lSevere braking
After rotation, inflate all tire pressures to
specification (page 10-6) and inspect the
lug nuts for tightness.
CAUTION
Rotate unidirectional tires and radial
tires that have an asymmetrical tread
pattern or studs only from front to rear,
not from side to side. Tire performance
will be weakened if rotated from side to
side.
CAUTION
Limited-Slip Differential system;
don't use the following:
lTires not of the designated size
lTires of different sizes or types at the
same time
lTires not sufficiently inflated
If these instructions aren't followed, the
rotation of the left and right wheels will
be different and will thus apply a
constant load on the limited-slip
differential.
This will cause a malfunction.
q Replacing a Tire
WARNING
Worn Tires:
Driving with worn tires is dangerous.
Reduced braking, steering, and
traction could result in an accident.
Always use tires that are in good
condition.
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tire when this happens.
New tread Tread wear indicator
Worn tread
You should replace it before the band is
across the entire tread.
qTemporary Spare Tire
Inspect the temporary spare tire at least
monthly to make sure it's properly inflated
and stored.
The temporary spare tire is easier to
handle because of its construction. It is
lighter and smaller than a conventional
tire and should be used only for an
emergency and only for a short distance.

Use the temporary only until the
conventional tire is repaired, which should
be as soon as possible.
Maintain its pressure at 420 kPa (4.2 kgf/
cm
2or bar, 60 psi).
CAUTION
lDon't use your temporary spare tire
rim with a snow tire or a
conventional tire. Neither will
properly fit and could damage both
tire and rim.
lThe temporary spare tire has a tread
life of up to 5,000 km (3,000 miles),
depending on road conditions and
driving habits.
lThe temporary spare tire is for
limited use, however, if the tread
wear solid-band indicator appears,
replace the tire with the same type of
temporary spare (page 8-32).
qReplacing a Wheel
WARNING
Using a Wrong-Sized Wheel:
Using a wrong-sized wheel is
dangerous. Braking and handling
could be affected, leading to loss of
control and an accident. Always use
wheels of the correct size on your
vehicle.
CAUTION
A wrong-sized wheel may adversely
affect:
lTire fit
lWheel and bearing life
lGround clearance
lSnow-chain clearance
lSpeedometer calibration
lHeadlight aim
lBumper height
lLimited-Slip Differential System
When replacing a wheel, make sure the
new one is the same as the original factory
wheel in diameter, rim width, and offset.
Proper tire balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tires can cause
vibration and uneven wear, such as
cupping and flat spots.
