tire pressure MAZDA MODEL CX-9 2021 Owners Manual

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 6-22.
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 6-20).
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
6-24).
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 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 4 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.

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.
WA R N I N G
Use only the same size and type tires (snow,
radial, or non-radial) on all 4 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
The tire pressure monitoring system may
not function correctly when using tires
with steel wire reinforcement in the
sidewalls (page 4-253).
▼ 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.
 Chains may scratch or chip aluminum
wheels.
NOTE
The tire pressure monitoring system may
not function correctly when using tire
chains.
Use of tire chains on a vehicle equipped
with P255/50R20 specification tires
could cause interference with the vehicle
body and scratching. If tire chains are to
be used, replace both front and rear tires
with P255/60R18 tires. Please consult
an Authorized Mazda Dealer.
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. 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).

CX-9_8JK1-EA-20G_Edition6_old 2021-12-8 9:30:44

Make sure there are no exhaust gas leaks into the passenger compartment if any mounting
bolts are connected to the body:
Modifying your vehicle exhaust system is dangerous. Exhaust gas entering the vehicle could
cause loss of consciousness or even death.
When mounting the trailer hitch, make no modifications to the vehicle exhaust system.
CAUTION
Make all hitch adjustments with actual loads. Do not load and unload vehicle while
adjusting hitch. This action wi ll change the vehicle height.
 Do not use an axle-mounted hitch. This may damage the axle and related parts.
▼ Tires
When towing a trailer, make sure all tires
are inflated to the recommended cold-tire
pressure, as indicated on the tire pressure chart on the driver's door frame. Trailer tire size,
load rating, and inflation pr essures should conform to ti re manufacturer specifications.
WA R N I N G
Never use the temporary spare tire when towing:
Using the temporary spare tire on your vehicle wh en towing a trailer is dangerous as it could
result in tire failure, loss of control, and injury to vehicle occupants.
▼ Safety Chains
Safety chains must be used as a precautionary measure should the trailer become
unintentionally unhitched. They should cross un
der the trailer tongue and attach to the hitch.
Leave enough slack to allow full turns. Consult literature published by your trailer or hitch
manufacturer for more details.
WA R N I N G
Make sure the safety chain is securely attached to both the trailer and the vehicle prior to
departure:
Towing a trailer without using a safety chain securely attached to both the trailer and the
vehicle is dangerous. If damage occurs to the coupling unit or hitch ball, the trailer could
wander into another lane and cause a collision.
▼ Trailer Lights
Trailer lights must comply with all federal, st
ate, and local regulations. Equip your trailer as
required before towing it day or night.

i-ACTIV AWD Operation*
AWD provides excellent drivability on
snow-covered and ice-packed roads, sand
and mud, as well as on steep slopes and
other slippery surfaces.
A system malfunction or operation
conditions are indicated by a warning.
Refer to Contact Authorized Mazda
Dealer and Have Vehicle Inspected on
page 7-31.
WARNING
Never spin a wheel that is off the ground:
Spinning a wheel that is off the ground as a
result of the vehicle being stuck or in a
ditch is dangerous. The drive assembly
could be seriously damaged which could
lead to an accident or could even lead to
overheating, oil leakage, and a fire.
▼ AWD Driving
WARNING
Avoid sharp turns, excessive speed and
abrupt maneuvers when driving this
vehicle:
Sharp turns, excessive speed and abrupt
maneuvering of this vehicle is dangerous
as it could result in the increased risk of loss
of vehicle control, vehicle roll-over,
personal injury or death.
This vehicle has a higher center of gravity.
Vehicles with a higher center of gravity
such as utility and AWD vehicles handle
differently than vehicles with a lower center
of gravity.
Utility and AWD vehicles are not designed
for cornering at high speeds any more than
low profile sports cars are designed to
perform satisfactorily under off-road
conditions. In addition, utility vehicles have
a significantly higher rollover rate than
other types of vehicles.
Drive carefully when the vehicle is loaded
by lowering vehicle speed and applying the
brakes earlier:
Abrupt maneuvering and sudden braking
when driving a loaded vehicle is dangerous
as the driving behavior of a vehicle with a
high center of gravity is different when it is
loaded compared to when it is not, and
could result in the loss of vehicle control
and an accident.
▼Tires and Tire Chains
The condition of the tires plays a large role
in the performance of the vehicle.
Moreover, to prevent adverse effects to the
drive assembly, please note the following:
Tires
When replacing tires, always replace all
front and rear tires at the same time.
All tires must be of the same size,
manufacture, brand and tread pattern.
Pay particular attention when equipping
snow or other types of winter tires.
Do not mix tread-worn tires with normal
tires.
Inspect tire inflation pressures at the
specified periods adjust to the specified
pressures.
NOTE
Check the tire inflation pressure label
attached to driver's door frame for the
correct tire inflation pressure.
