ser MAZDA MODEL CX-30 2021 Repair Manual

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 4-75.
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.

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
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
6-19.
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 6-21).
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.

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
Authorized Mazda Dealer.

▼Transmission Ranges
The shift position indication in the
instrument cluster illuminates.
Refer to Shift Position Indication on
page 4-36.
Shift the selector lever to the P or N
position to start the engine.
P (Park)
P locks the transmission and prevents
the front wheels from rotating.
WARNING
Always set the selector lever to P
position and set the parking brake:
Only setting the selector lever to the P
position without using the parking
brake to hold the vehicle is dangerous.
If P fails to hold, the vehicle could
move and cause an accident.
CAUTION
 Shifting into P, N or R while the
vehicle is moving can damage your
transmission.
 Shifting into a driving gear or reverse
when the engine is running faster
than idle can damage the
transmission.
R (Reverse)
In position R, the vehicle moves only
backward. You must be at a complete
stop before shifting to or from R,
except under rare circumstances as
explained in Rocking the Vehicle (page
3-52).
N (Neutral)
In N, the wheels and transmission are
not locked. The vehicle will roll freely
even on the slightest incline unless the
parking brake or brakes are on.
WARNING
If the engine is running faster than
idle, do not shift from N or P into a
driving gear:
It's dangerous to shift from N or P into
a driving gear when the engine is
running faster than idle. If this is done,
the vehicle could move suddenly,
causing an accident or serious injury.
Do not shift into N when driving the
vehicle:
Shifting into N while driving is
dangerous. Engine braking cannot be
applied when decelerating which
could lead to an accident or serious
injury.
