Rocking the Vehicle
WA R N I N G
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, transaxle 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
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 6-25.
•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 6-22).
•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
6-27).
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.
Before Driving
Driving Tips
3-45
CX-3_8GR7-EA-18B_Edition1 2017-12-20 16:18:14

•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/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.

Except Mexico
The vehicle is original ly 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.
Mexico
The vehicle is origin ally 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.
WA R N I N G
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 vehi cle'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 4-145).
▼ 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.
Before Driving
Driving Tips
3-46
CX-3_8GR7-EA-18B_Edition1 2017-12-20 16:18:14

Chains may scratch or chip aluminum
wheels.
NOTE
•If your vehicle is equipped with the tire
pressure monitoring system, the system
may not function corr ectly when using
tire chains.
Install the chains on the front tires only.
Do not use chains on the rear tires.
Please consult an Authorized Mazda
Dealer.
Installing the chains
1. If your vehicle is equipped with wheel covers remove them, otherwise the
chain bands will scratch them.
2. Secure the chains on the front tires as
tightly as possible.
Always follow the chain
manufacturer's instructions.
3. Retighten the ch ains after driving
1/2―1 km (1/4―1/2 mile).
Driving In Flooded Area
WA R N I N G
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.

Ignition Switch
▼Push Button Start Positions
The system operates only when the driver
is in the vehicle or within operational
range while the key is being carried.
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.
Push button start Indicator light
NOTE
•The engine starts by pressing the push
button start while depressing the clutch
pedal (manual transaxle) or the brake
pedal (automatic transaxle). 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 transaxle, 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.
WA R N I N G
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 transaxle) or in 1st gear or R
(manual transaxle):
Leaving the driver's seat without switching
the ignition off, setting the parking brake,
and shifting the selector lever to P
(automatic transaxle) or to 1st gear or R
(manual transaxle) 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.

ON
This is the normal running position after
the engine is started. The indicator light
(amber) turns off. (The indicator light
(amber) illuminates when the ignition is
switched ON and the engine is not
running.)
Some indicator lights/warning lights
should be inspected before the engine is
started (page 4-24).
NOTE
When the push button start is pressed to
ON, the sound of the fuel pump motor
operating near the fuel tank can be heard.
This does not indi cate an abnormality.
Starting the Engine
WA R N I N G
Radio waves from the key may affect
medical devices such as pacemakers:
Before using the key near people who use
medical devices, ask the medical device
manufacturer or your physician if radio
waves from the key w ill affect the device.
NOTE
•The key must be carried because the key
carries an immobilizer chip that must
communicate with the engine controls at
short range.
•The engine can be started when the push
button start is pressed from off, ACC, or
ON.
•The push button start system functions
(function which can start the engine by
only carrying the key) can be
deactivated to prevent any possible
adverse effect on a user wearing a
pacemaker or other medical device. If
the system is deactivated, you will be
unable to start the engine by carrying
the key. Consult an Authorized Mazda
Dealer for details. If the push button
start system functions have been
deactivated, you can start the engine by
following the procedure indicated when
the key battery goes dead.
Refer to Engine Start Function When
Key Battery is Dead on page 4-8.
•After starting a cold engine, the engine
speed increases and a whining sound
from the engine compartment can be
heard.
