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 4-84.
If you get stuck, select a lower gear
and accelerate slowly. Do not spin
the front 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 front wheels.
NOTE
Use snow chains only on the front
wheels.
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
floor mat so that its grommets are
inserted over the pointed end of the
retention posts.

1/2 ―1 km (1/4 ―1/2 mile).
Driving In Flooded Area
▼Driving In Flooded Area
WARNING
Dry off 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
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
