Driving Tips
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.
When driving on ice or in water, snow,
mud, sand, or similar hazards:
 Be cautious and allow extra distance for
braking. Avoid sudden braking and sudden
maneuvering. Do not pump the brakes. Continue to
press down on the brake pedal.
Refer to Antilock Brake System (ABS)
on page 4-55. If you get stuck, select a lower gear and
accelerate slowly. Do not spin the rear
wheels. For 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 rear
wheels.
NOTE
Use snow chains only on the rear 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.
If 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 grommets are inserted over
the pointed end of the retention posts.

Before Driving
Driving Tips
 Drive slowly. Braking performance
can be adversely affected if snow or
ice adheres to the brake components. If
this situation occurs, drive the vehicle
slowly, releasing the accelerator pedal
and lightly applying the brakes several
times until the brake performance
returns to normal.
Snow 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/cm2, 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.
The 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, Mazda recommends that
you replace the tires originally equipped
on your vehicle with snow tires during the
winter months.
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.
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
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 rear tires only.
Do not use chains on the front tires.
Please consult an Authorized Mazda
Dealer.
Installing the chains
1. Secure the chains on the rear tires as
tightly as possible.
Always follow the chain manufacturer's
instructions.
2. Retighten the chains after driving
1/2—1 km (1/4—1/2 mile).

When Driving
Start/Stop Engine
Ignition Switch
Push Button Start Positions
The system operates only when the key is
within operational range.
Each time the push button start is pressed,
the ignition switches in the order of off,
ACC, and ON. Pressing the push button
start again from ON switches the ignition
off.
Indicator light
NOTE
 The engine starts by pressing the push
button start while depressing the clutch
pedal (manual transmission) or the
brake pedal (automatic transmission).
To switch the ignition position, press the
push button start without depressing the
pedal. Do not leave the ignition switched
ON while the engine is not running.
Doing so could result in the battery
going dead. If the ignition is left in
ACC (For automatic transmission, the
selector lever is in the P position, and
the ignition is in ACC), the ignition
switches off automatically after about
25 minutes.
Off
The power supply to electrical devices
turns off and the push button start indicator
light (amber) also turns off.
In this position the steering wheel is
locked.
WARNING
Before leaving the driver's seat, always
switch the ignition off, set the parking
brake, and make sure the selector lever
is in P (automatic transmission) or in 1st
gear or R (manual transmission):
Leaving the driver's seat without
switching the ignition off, setting the
parking brake, and shifting the selector
lever to P (automatic transmission) or
to 1st gear or R (manual transmission)
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.
ACC (Accessory)
Some electrical accessories will operate
and the indicator light (amber) illuminates.
NOTE
The keyless entry system does not function
while the push button start has been
pressed to ACC, and the doors will not
lock/unlock even if they have been locked
manually.
