warning light MAZDA MODEL CX-9 2018 (in English) Workshop 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.
Refer to Warning Indication/Warning
Lights on page 4-32.
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.
Refer to Warning Indication/Warning
Lights on page 4-32.
WA R N I N G
Do not rely on the Traction Control System
(TCS) as a substitute for safe driving:
The Traction Control System (TCS) cannot
compensate for unsafe and reckless
driving, excessive speed, tailgating
(following another vehicle too closely), and
hydroplaning (reduced tire friction and
road contact because of water on the road
surface). You can still have an accident.
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 co uld still have an
accident.
NOTE
To turn off the TCS, press the TCS OFF
switch (page 4-74).
â–¼ 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
Assist (TSA)
* is operating, the indicator
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 -72) and TCS (page
4-73).

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

The warning light turns on when the
system has a malfunction.
Refer to Warning Indication/Warning
Lights on page 4-32.

CAUTION
 The DSC may not operate correctly
unless the following are observed:
 Use tires of the correct size
specified for
your Mazda on all four wheels.
 Use tires of the same manufacturer,
brand and tread pattern on all four
wheels.
 Do not mix worn tires.
 The DSC may not operate correctly when
tire chains are used or a temporary spare
tire is installed because the tire diameter
changes.

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 Warning Indication/Warning
Lights on page 4-32.
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.
â–¼ AW D D r i v i n g
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.

Power Steering
•Power steering is only operable when
the engine is running. If the engine is off
or if the power steering system is
inoperable, you can still steer, but it
requires more physical effort.
If the steering feels stiffer than usual
during normal driving or the steering
vibrates, consult an Authorized Mazda
Dealer.
•The warning indication/warning light
notifies the driver of system
abnormalities and operation conditions.
In addition, the buzzer may also activate
depending on the system abnormality or
operation condition.
Refer to Warning Indication/Warning
Lights on page 4-32.
Refer to Power Steering Warning
Buzzer on page 7-50.
CAUTION
Never hold the steering wheel to the
extreme left or right for more than 5
seconds with the engine running. This
could damage the power steering system.

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 Warning/Indicator Lights on page 4-31.
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.
The warning light turns on when the system has a malfunction.
Refer to Warning Indication/Warning Lights on page 4-32.
CAUTION

Do not adjust the vehicle height, modify th e headlight units, or remove the camera,
otherwise the system will not operate normally.
 Do not rely excessively on the HBC and drive the vehicle while paying sufficient attention to
safety. Switch the headlights between the high beams and low beams manually if
necessary.

Blind Spot Monitoring (BSM)*
The BSM is designed to assist the driver in checking the area to the rear of the vehicle on
both sides during lane changes by notifying the driver of the p resence of vehicles
approaching from the rear in an adjacent lane.
The BSM detects vehicles approaching from the rear while travel ing in the forward
direction at a speed of 10 km/h (6.3 mph) or faster and notifie s the driver by turning on the
BSM warning indicator light and displaying the vehicle detectio n screen (vehicles with
multi-information display and active driving display).
If the turn signal lever is operated to signal a turn in the direction in which the BSM
warning indicator light is illumi nated while the approaching vehicle is detected, the BSM
notifies the driver of possible danger by turning on the BSM wa rning indicator light, and by
activating the warning sound and the warning screen indicator display (vehicles with
multi-information display and active driving display).
The detection area on this system covers the driving lanes on b oth sides of the vehicle and
from the rear part of the front d oors to about 50 m (164 ft) behind the vehicle.

WA R N I N G
Always check the surrounding area visually before making an actual lane change:
The system is only designed to assist you in checking for vehicles at your rear when making a
lane change. Due to certain limitations with
the operation of this system, the BSM warning
indicator light, the warning sound and the warning screen indicator display may not activate
or they might be delayed even though a vehicle is in an adjacent driving lane. Always make it
your responsibility as a driver to check the rear.
