Floor Mat
▼Floor Mat
We recommend the use of Genuine
Mazda
floor mats.
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.
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
fl oor mat so that its grommets are
inserted over the pointed end of the
retention posts.
Rocking the Vehicle
▼ Rocking the Vehicle
WARNING
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 , transmission 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 shift lever/selector lever from 1 (D)
to R position.

Winter Driving
▼Winter Driving
Carry 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
check the following:
Have the proper ratio of antifreeze in
the radiator.
Refer to Engine Coolant on page
6-20.
Inspect the battery and its cables.
Cold reduces battery capacity.
Use an engine oil appropriate for the
lowest ambient temperatures that
the vehicle will be driven in (page
6-17).
Inspect the ignition system for
damage and loose connections.
Use washer fluid made with
antifreeze ―but do not use engine
coolant antifreeze for washer fluid
(page 6-22).
NOTE
Remove snow before driving. Snow
left on the windshield is dangerous
as it could obstruct vision.
Do not apply excessive force to a
window scraper when removing ice
or frozen snow on the mirror glass
and windshield.
Never use warm or hot water for
removing snow or ice from windows
and mirrors as it could result in the
glass cracking.
Drive slowly. Braking performance
can be adversely a ffected 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 4 wheels
Do not go faster than 120 km/h (75
mph) while driving with snow tires.
In
flate 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.

Mexico
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.
Except Mexico
The 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.

Driving In Flooded Area
▼Driving In Flooded Area
WARNING
Dry o
ff brakes that have become wet
by driving slowly, releasing the
accelerator pedal and lightly applying
the brakes several times until the
brake performance returns to normal:
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
a ff ected.
CAUTION
Do not drive the vehicle on flooded
roads as it could cause short circuiting
of electrical/electronic parts, or engine
damage or stalling from water
absorption. If the vehicle has been
immersed in water, consult an
Authorized Mazda Dealer.
Overloading
▼ Overloading
WARNING
Be careful not to overload your
vehicle:
The gross axle weight rating (GAWR)
and the gross vehicle weight rating
(GVWR) of the vehicle are on the
Motor Vehicle Safety Standard Label
on the driver's door frame. Exceeding
these ratings can cause an accident or
vehicle damage. You can estimate the
weight of the load by weighing the
items (or people) before putting them
in the vehicle.

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.
1. Indicator light
2. Push button start
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 o ff automatically
after about 25 minutes.
O ff
The power supply to electrical devices
turns off and the indicator light
(amber) also turns off .
WARNING
Before leaving the driver's seat,
always switch the ignition o ff, set the
parking brake, and make sure the
selector lever is in P (automatic
transmission) position 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 (automat ic transmission)
position 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.
