warning light MAZDA CX90 2024 Service Manual

Hill Launch Assist (HLA)
The HLA prevents the vehicle from
rolling backward or forward, such as
when releasing the brake pedal while
on a slope.
NOTE
The HLA may not operate on a gentle
slope or depending on the vehicle’s
load.
The HLA does not operate if the
parking brake is applied or the
vehicle has not stopped completely.
When the TCS/DSC operation
indicator light
turns on, the HLA
may not operate.
The HLA does not turn off even if the
TCS is turned off.
Warning and Cautions for
Using the Hill Launch Assist (HLA)
WARNING
Do not rely completely on the HLA.
The HLA is designed only to assist the
driver in accelerating from a stop on a
slope. The HLA only operates for about
2 seconds and therefore, if the
accelerator and brake pedals are not
operated correctly the vehicle may
move (roll) unexpectedly and cause an
accident. Always confirm the safety
around the vehicle before starting to
drive the vehicle. Note that the vehicle
may move suddenly depending on the
vehicle’s load or if it is towing
something.

Antilock Brake System(ABS)
The ABS prevents the wheels from
locking, caused by braking on slippery
roads, and maintains driving
directional stability and ensures
steerability.
NOTE
When depressing the brake pedal,
slight vibration might be felt from the
pedal. This vibration is a normal
occurrence when the ABS operates.
ABS does not operate at low speeds
(about 10 km/h (6.2 mph) or
slower).
Warning and Cautions forUsing the Antilock Brake System (ABS)
WARNING
Do not rely on the 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.
CAUTION
Always use tires of the specified size
and type for the front and rear wheels.
If a tire other than the specified size or
type is installed, the ABS system may
not operate normally.

Trailer Stability Control(TSC)
The TSC is a system that increases the
stability of the vehicle during towing.
When vehicle sway occurs during
towing, the TSC controls the output of
the brakes and the hybrid system to
suppress swaying.
Warning and Cautions forUsing the Trailer Stability Control (TSC)
WARNING
Do not rely solely on the Trailer
Stability Control (TSC).
Vehicle stability can be 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.
CAUTION
 The Trailer Stability Control (TSC)
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 Trailer Stability Control (TSC)
may not operate correctly when tire
chains are used or a temporary spare
tire is installed because the tire
diameter changes.

Tire Pressure MonitoringSystem (TPMS)
The TPMS monitors the air pressure of
each tire and informs the driver of a
decrease in the tire air pressure when it
becomes lower than the specified air
pressure.
For the TPMS, the air pressure data
sent from the tire pressure sensors
installed on each wheel via radio signal
is received by the receiver unit in the
vehicle to monitor the tire pressures.
1. Tire pressure sensor
Warning and Cautions forUsing the Tire Pressure Monitoring System
(TPMS)
WARNING
Do not drive the vehicle at high
speeds if the TPMS warning light
is
turned on or flashing.
Driving the vehicle at high speeds
while the TPMS warning light is turned
on or flashing is dangerous because
the brake performance and the
steering wheel operability will be
reduced. If the vehicle is driven at high
speeds or the brakes are suddenly
applied, it could lead to an accident.
Gradually apply the brake and reduce
the vehicle speed.
Do not ignore the TPMS warning light
when it is turned on or flashing.
Continuing to driv e the vehicle while
ignoring the illumi nation/flashing of
the TPMS warning light is dangerous
because a tire may burst which could
lead to an accident. Take appropriate
measures as soon as possible.

How to Use the Tire
Pressure Monitoring System (TPMS)
Check the tire pressure
The current tire pressure can be
checked on the center display.
Refer to the Vehicle Status Monitor
section in the Mazda Connect
Owner's Manual.
Low tire pressure warning
When a tire pressure of the specified
air pressure or lower is detected, the
TPMS warning light
turns on and a
warning indication is displayed in the
instrument cluster.
1. Message is displayed.
Action
1. Adjust the tire pressure to the appropriate pressure.
Refer to the Tires on page 10-71.
CAUTION
If the tire pressure is adjusted when
the tire is warm, the tire pressure
may lower below the specified
pressure after cooling and the
warning light may turn on. Adjust
the air pressure of the tires when
they are cold.
2. Make sure that the TPMS warning
light
is turned off.
3. If the TPMS warning light does
not turn off, drive the vehicle for 3
minutes or longer at a speed of 25
km/h (16 mph) or faster.
4. Make sure that the TPMS warning
light
is turned off.
If the TPMS warning light remains on
even after adjusting the tire pressure,
there is a possibility that the tire is flat.
CAUTION
When inspecting/adjusting the tire
pressures, do not apply excessive force
to the air valve of the tire pressure
sensor. Otherwise, the tire pressure
sensor could be damaged.
When changing tires and wheels
When changing the tires or wheels
(such as installing winter tires), it will
be necessary to register the ID signal
code of the tire pressure sensor to the
TPMS.
Have an Authorized Mazda Dealer do
the registration or register the ID signal
codes of the tire pressure sensors using
the following procedure.
NOTE
The tire pressure sensors on each
wheel have a unique ID signal code.
For the TPMS to operate correctly, the
ID signal codes of the tire pressure
sensors need to be registered to the
system.
1. Wait more than 19 minutes after changing a tire or wheel.
2. After more than 19 minutes have passed, drive the vehicle at a speed
of 25 km/h (16 mph) or faster for 3
minutes or longer. While driving,
the ID signal codes of the tire
pressure sensors are automatically
registered.

NOTE
If you drive the vehicle within 19
minutes of changing a tire or wheel,
the TPMS warning light
will flash
because the ID signal codes for the tire
pressure sensors were not registered.
In this case, stop the vehicle and
register the ID signal codes of the tire
pressure sensors following the
procedure.
When replacing tires and wheels
CAUTION
 When replacing the tires and wheels,
consult an Authorized Mazda Dealer
Otherwise, the tire pressure sensors
could be damaged when replacing
them.
 Do not install non-genuine wheels. If
