spec MAZDA CX9 2023 Repair Manual

Antilock Brake System(ABS)
The ABS control unit continuously
monitors the speed o f each wheel. If one
wheel is about to lock up, the ABS
responds by automatically releasing and
reapplying that wheel's brake.

The driver will feel a slight vibration in
the brake pedal and may hear a chattering
noise from the brake system. This is
normal ABS system operation. Continue
to depress the brak e pedal without
pumping the brakes.

The warning light turns on when the
system has a malfunction.
Contact an Authorized Mazda Dealer and
Have Vehicle Inspected on page 7-31.
WA R N I N G
Do not rely on ABS as a substitute for safe
driving:
The ABS cannot compensate for unsafe
and reckless driving, excessive speed,
tailgating (following another vehicle too
closely), driving on ice and snow, and
hydroplaning (reduced tire friction and
road contact because of water on the road
surface). You can still have an accident.
NOTE
Braking distances may be longer on
loose surfaces (snow or gravel, for
example) which usually have a hard
foundation. A vehicle with a normal
braking system may require less
distance to stop under these conditions
because the tires wi ll build up a wedge
of surface layer when the wheels skid.
The sound of the ABS operating may be
heard when starting the engine or
immediately after starting the vehicle,
however, it does not indicate a
malfunction.

Traction Control System(TCS)
The Traction Control System (TCS)
enhances traction and safety by controlling
engine torque and braking. When the TCS
detects driving wheel slippage, it lowers
engine torque and operates the brakes to
prevent loss of traction.
This means that on a slick surface, the
engine adjusts automatically to provide
optimum power to the drive wheels,
limiting wheel spin and loss of traction.
The warning light turns on when the
system has a malfunction.

Use snow tires or tire chains and drive at
reduced speeds when roads are covered
with ice and/or snow:
Driving without proper traction devices on
snow and/or ice-covered roads is
dangerous. The Traction Control System
(TCS) alone cannot provide adequate
traction and you could still have an
accident.
NOTE
To turn off the TCS, press the TCS OFF
switch (page 4-106).
▼ TCS/DSC Indicator Light
This indicator light stays on for a few
seconds when the ignition is switched ON.
If the TCS, DSC or the Trailer Stability

light flashes.

If the light stays on, the TCS, DSC or the
brake assist system may have a
malfunction and they may not operate
correctly. Take your vehicle to an
Authorized Mazda Dealer.
NOTE
In addition to the indicator light
flashing, a slight lugging sound will
come from the engine. This indicates
that the TCS/DSC is operating properly.
On slippery surfaces, such as fresh
snow, it will be impossible to achieve
high rpm when the TCS is on.

Dynamic Stability Control(DSC)
The Dynamic Stability Control (DSC)
automatically controls braking and engine
torque in conjunction with systems such as
ABS and TCS to help control side slip
when driving on slippery surfaces, or
during sudden or evasive maneuvering,
enhancing vehicle safety.

Refer to ABS (page 4-104) and TCS (page
4-105).

DSC operation is possible at speeds
greater than 20 km/h (12 mph).

The warning light turns on when the
system has a malfunction.

Control (TSC) automatically controls
braking and engine torque to suppress the
swaying and enhance vehicle stability.
The Trailer Stabili ty Control (TSC) is
operable at a vehicle speed of about 65
km/h (40 mph) or more.
When the Trailer Sta bility Control (TSC)
operates while driving the vehicle, the
TCS/DSC indicator light flashes.

WA R N I N G
Do not rely solely on the Trailer Stability
Control (TSC)
Assured vehicle stability is limited even if
the Trailer Stability Control (TSC) is
operating. Drive carefully to prevent
accidents.
In particular, if the TCS/DSC indicator light
is flashing, drive the vehicle carefully as it is
in a less stable condition and could sway
more easily. Drive with caution and in
accordance with the road, vehicle and
trailer conditions.

Off-Road Traction Assist*
When the vehicle tires become embedded
in mud, sand, or deep snow, the Off-Road
Traction Assist functions to prevent
drive-wheel spinning and to assist in
freeing tires that are stuck.
Do not drive over rough rocky roads and
river beds.
WA R N I N G
Do not rely completely on the Off-Road
Traction Assist.
The Off-Road Traction Assist has
limitations. Always drive the vehicle safely
according to the road conditions. Do not
drive the vehicle recklessly, otherwise it
may result in an accident. In addition, do
not drive the vehicle under the following
conditions while the Off-Road Traction
Assist is operating. Otherwise, it could
negatively affect the drivetrain parts which
could result in an accident.
 Vehicle is driven on paved roads.
 Temporary spare tire or tires of a
different specified size are used.
 Tire chains are used.
CAUTION
The
Off-Road Traction Assist is a function

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.
Contact an Authorized Mazda Dealer and
Have Vehicle Inspected on page 7-31.
WA R N I N G
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
WA R N I N G
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 ti
res 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.

High Beam Control System (HBC)*
The HBC determines the conditions in front of the vehicle using the Forward Sensing
Camera (FSC) while driving in darkness to automatically switch the headlights between
high and low beams.
Refer to Forward Sensing Camera (FSC) on page 4-239.
While driving the vehicle at a speed of about 30 km/h (19 mph) or more, the headlights are
switched to high beams when there are no vehicles ahead or appr oaching in the opposite
direction.
The system switches the headlight s to low beams when one of the following occurs:
The system detects a vehicle or the headlights/lights of a vehi cle approaching in the
opposite direction.
The vehicle is driven on roads lined with streetlamps or on roa ds in well-lit cities and
towns.
The vehicle is driven at less than about 20 km/h (12 mph).
Forward Sensing
Camera (FSC)
The recognition distance of the
Forward Sensing Camera (FSC)
varies according to the
surrounding conditions.
