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.
Refer to Engine Coolant on page 8-23.
lInspect the battery and its cables. Cold
reduces battery capacity.
lUse only cold-weather engine oil (page
8-19).
lInspect the ignition system for damage
and loose connections.
lUse washer fluid made with
antifreeze―but do not use engine
coolant antifreeze for washer fluid
(page 8-29).
lDo not use the parking brake in
freezing weather as it may freeze.
Instead, shift to P and block the rear
wheels.
lDo not apply excessive force to a
window scraper when removing ice or
frozen snow on the mirror glass and
windshield.
lNever use warm or hot water for
removing snow or ice from windows
and mirrors as it could result in the
glass cracking.
lBraking performance can be adversely
affected if snow or ice adheres to the
brake equipment. 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.
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
5-33).

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.
Please consult an Authorized Mazda
Dealer.
Installing the chains
1. Secure the chains on the front 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).
Driving In Flooded Area
WARNING
Dry wet brakes by driving very slowly
and applying the brakes lightly until
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 affected.
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.

warning light illuminated. Contact an
Authorized Mazda Dealer to have the
brakes inspected as soon as possible:
Driving with the brake system
warning light illuminated is
dangerous. It indicates that your
brakes may not work at all or that

time. If this light remains
illuminated, after checking that the
parking brake is fully released, have
the brakes inspected immediately.
qABS Warning Light
The warning light stays on for a few
seconds when the ignition is switched
ON.
If the ABS warning light stays on while
you're driving, the ABS control unit has
detected a system malfunction. If this
occurs, your brakes will function normally
as if the vehicle had no ABS.
Should this happen, consult an Authorized
Mazda Dealer as soon as possible.NOTE
lWhen the engine is jump-started to charge
the battery, uneven rpm occurs and the ABS
warning light may illuminate. If this occurs,
it is the result of the weak battery and does
not indicate an ABS malfunction.
Recharge the battery.
lThe brake assist system does not operate
while the ABS warning light is illuminated.
qElectronic Brake Force
Distribution System Warning
If the electronic brake force distribution
control unit determines that some
components are operating incorrectly, the
control unit may illuminate the brake
system warning light and the ABS
warning light on simultaneously. The
problem is likely to be the electronic
brake force distribution system.
WARNING
Do not drive with both the ABS warning
light and brake warning light
illuminated. Have the vehicle towed to
an Authorized Mazda Dealer to have
the brakes inspected as soon as
possible:
Driving when the brake system
warning light and ABS warning light
are illuminated simultaneously is
dangerous.

rear wheels could lock more quickly
in an emergency stop than under
normal circumstances.
