(we recommend an Authorised Mazda
Repairer) as soon as possible.
Refer to Emergency Operation for
Starting the Engine on page 4-9.
“Key Not Detected” is displayed
xIf the presence of the key cannot be
detected (dead battery, battery

while the indicator light is
flashing , you
will not be able to restart it.
Make sure the key is within the
operational range for signal
transmission. Switch the ignition off,
and then restart the engine. If the
engine does not start after 3 or more
tries, contact an expert repairer (we
recommend an Authorised Mazda
Repairer).
NOTE
Because the electronic codes are reset
when the immobilizer system is

▼120 km/h Warning Light*
The 120 km/h warning light
illuminates when the vehicle speed
exceeds 120 km/h.
Action to be taken
Lower the vehicle speed.
▼Tyre Pressure Monitoring System
(TPMS) Warning Indication/
Warning Light (Flashing)
*
If there is a problem with the TPMS or
the voltage of a tyre pressure sensor
decreases, the TPMS warning light
flashes and a message is displayed on
the multi-information display. Have
your vehicle inspected by an expert
repairer (we recommend an
Authorised Mazda Repairer).
WARNING
Do not drive the vehicle at high
speeds if the TPMS warning light turns
on or flashes:
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 brakes to lower the
vehicle's speed.
If Trouble Arises

driven with the lights not turned on, it
may conflict with laws and regulations
due to poor maintenance.
▼Low Fuel Warning Indication/
Warning Light
The light turns on when the remaining
fuel is about 9.0 L (2.3 US gal, 1.9 Imp

passenger's seat is occupied) and the
vehicle is driven at a speed faster than
about 20 km/h (12 mph), the warning
light flashes. After a short time, the
warning light stops flashing, but
remains illuminated. If a seat belt
remains unfastened, the warning light

belt is unfastened after the warning
light turns on, and the vehicle speed
exceeds 20 km/h (12 mph), the
warning light flashes again.
xPlacing heavy items on the front
passenger's seat may cause the front
passenger's seat belt warning
function to operate depending on
the weight of the item.
xTo allow the front passenger seat
weight sensor to function properly,
do not place and sit on an additional
seat cushion on the front passenger's
seat. The sensor may not function
properly because the additional seat
cushion could cause sensor
interference.
xIf a small child is seated on the front
passenger's seat, the warning light
may not operate.

washer fluid remains.
Action to be taken
Add washer fluid (page 6-31).
▼Door-Ajar/Liftgate-Ajar Warning
Indication/Warning Light
The light turns on if any door/liftgate is
not closed securely.
Action to be taken
Close the door/liftgate securely.
▼Tyre Pressure Monitoring System
(TPMS) Warning Indication/
Warning Light (Turns on)
*
If a tyre pressure decreases below the
specified air pressure, the TPMS
warning light turns on.
At the same time, a message and the
tyre pressure of each tyre are displayed
on the multi-information display
alternately. In addition, the tyre (s)
with low air pressure is displayed in
yellow.
WARNING
Do not drive the vehicle at high
speeds if the TPMS warning light turns
on or flashes:
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 brakes to lower the
vehicle's speed.
If Trouble Arises
Warning/Indicator Lights and Warning Sounds
7-60*Some models.

Do not ignore the TPMS warning light
when it is turned on or flashing:
Continuing to drive the vehicle while
ignoring the illumination/flashing of
the TPMS warning light is dangerous
because a tyre may burst which could
lead to an accident. Take appropriate
measures as soon as possible.
NOTE
While the TPMS is learning the tyre
positions, such as immediately after a
tyre position has been changed, the
tyre pressure at the tyre position prior
to it being changed is displayed until
the system completes the learning. For
this reason, the tyre pressures
displayed for the tyre positions may be
different from the actual tyre pressures
at the tyre positions.
Action to be taken
Adjust the tyre pressures to the
appropriate pressures.
Refer to Tyre Inflation Pressure on page
6-41.
CAUTION
¾Adjust the tyre pressures while the
tyres are cool. Because the air
pressure in the tyres fluctuates
depending on the temperature,
before adjusting the tyre pressures,
let the vehicle sit for an hour or drive
it only within a 1.6 km (1 mile)
distance. If the tyre pressures are
adjusted while the tyres are warm,
the tyre pressures may decrease
below the specified air pressure after
cooling down which could turn on
the warning light. In addition,
because the air pressure in the tyres
decreases when the ambient
temperature is low, if the ambient
temperature increases, an
illuminated TPMS warning light may
turn off. Under any circumstances,
always adjust the tyre pressures while
the tyres are cool.
¾After adjusting the tyre pressures, the
TPMS warning light turns off. If the
TPMS warning light does not turn
off,
drive the vehicle at a speed of about
25 km (16 mph) or faster for 3
minutes or longer and make sure the
warning light turns off.
If the TPMS warning light remains on
even after adjusting the tyre pressures,
one of the tyres may have a puncture.
