ECU MAZDA MODEL CX-50 2023 Owner's Manual

WARNING
Follow the manufacturer's
instructions for the use of the
child-restraint system:
An unsecured child-restraint system is
dangerous. In a sudden stop or a
collision it could move causing serious
injury or death to the child or other
occupants. Make sure the
child-restraint system is properly
secured in place according to the
child-restraint system manufacturer's
instructions.
Never attach two child-restraint
systems to the same ISOFIX/LATCH
*1
lower anchor:
Attaching two child-restraint systems
to the same ISOFIX/LATCH
*1 lower
anchor is dangerous. In a collision, one
anchor may not be strong enough to
hold two child-restraint system
attachments, and it may break, causing
serious injury or death. If you use the
seat position for another child-restraint
system when an outboard ISOFIX/
LATCH
*1 position is occupied, use the
center seat belts instead, and the
tether if tether-equipped.
Make sure the child-restraint system is
properly secured:
An unsecured child-restraint system is
dangerous. In a sudden stop or a
collision it could move causing serious
injury or death to the child or other
occupants. Follow the child-restraint
system manufacturer's instructions on
belt routing to secure the seat just as
you would with a child in it so that
nobody is tempted to put a child in an
improperly secured seat later on.
When not in use, remove it from the
vehicle or fasten it with a seat belt, or
attach it to BOTH ISOFIX/LATCH
*1
lower anchors for ISOFIX/LATCH*1
child-restraint systems.
Make sure there are no seat belts or
foreign objects near or around the
ISOFIX/LATCH
*1 child-restraint
system:
Not following the child-restraint system
manufacturer's instructions when
installing the child-restraint system is
dangerous. If seat belts or a foreign
object prevent the child-restraint
system from being securely attached to
the ISOFIX/LATCH
*1 lower anchors
and the child-restraint system is
installed improperly, the child-restraint
system could move in a sudden stop or
collision causing serious injury or death
to the child or other occupants. When
installing the child-restraint system,
make sure there are no seat belts or
foreign objects near or around the
ISOFIX/LATCH
*1 lower anchors.
Always follow the child-restraint
system manufacturer's instructions.
*1 ISOFIX (Mexico)/LATCH (Except
Mexico)

Refer to Adjusting the Driver's Seat
on page 2-4.
Refer to Adjusting the Front
Passenger's Seat on page 2-12.
2. Make sure the seatback is securely latched by pushing it back until it is
fully locked.
3. Remove the cover of the child-restraint system's ISOFIX/
LATCH
*1 lower anchors to verify the
locations of the ISOFIX/LATCH*1
lower anchors.
1. Lower anchor

NOTE
The ISOFIX/LATCH*1 lower
anchors marking on the cover
indicates the position of the
ISOFIX/LATCH
*1 lower anchors
for the attachment of a
child-restraint system.
Store the removed cover so that it
does not get lost.
4. Remove the head restraint. However, when installing a backless
booster seat, always install the
vehicle head restraint to the seat
where the backless booster seat is
installed.
Refer to Head Restraints on page
2-15.
5. Secure the child-restraint system
using BOTH ISOFIX/LATCH*1 lower
anchors, following the
child-restraint system
manufacturer's instruction. Pull on
the child-restraint to be sure both
anchors are engaged.
6. If your child-restraint system came equipped with a tether, that means
it is very important to properly
secure the tether for child safety.
Please carefully follow the
child-restraint system
manufacturer's instructions when
installing tethers.
*1ISOFIX (Mexico)/LATCH (ExceptMexico)
WARNING
Use the tether and tether anchor only
for a child-restraint system:
Using the tether or tether anchor to
secure anything but a child-restraint
system is dangerous. This could
weaken or damage the tether or tether
anchor and result in injury.

specified time after the ignition is
switched ON.


Small children must be protected by a
child-restraint system as stipulated by
law in every state and province. In
certain states and provinces, larger
children must use a child-restraint
system (page 2-31).

Carefully consider which child-restraint
system is necessary for your child and
follow the installation directions in this
Owner's Manual as well as the
child-restraint system manufacturer's
instructions.
WARNING
Seat belts must be worn in air bag
equipped vehicles:
Depending only on the air bags for
protection during an accident is
dangerous. Alone, air bags may not
prevent serious injuries. The
appropriate air bags can be expected
to inflate only in the first accident, such
as frontal, near frontal or side collisions
or roll-over accidents that are at least
moderate. Vehicle occupants should
always wear seat belts.

Children should not ride in the front
passenger seat:
Placing a child, 12 years or under, in
the front seat is dangerous. The child
could be hit by a deploying air bag and
be seriously injured or even killed. A
sleeping child is more likely to lean
against the door and be hit by the side
air bag in moderate collision to the
front-passenger side of the vehicle.
Whenever possible, always secure a
child 12 years and under on the rear
seats with an appropriate
child-restraint system for the child's
age and size.
Never use a rear-facing child-restraint
system in the front seat with an air
bag that could deploy:
Rear-facing child-restraint systems on
the front seat are particularly
dangerous even though you may feel
assured that a front passenger air bag
will not deploy based on the fact that
the front passenger air bag
deactivation indicator light illuminates.
The child-restraint system can be hit by
a deploying air bag and moved
violently backward resulting in serious
injury or death to the child.

WARNING
Always take all children and pets with
you or leave a responsible person
with them:
Leaving a child or a pet unattended in
a parked vehicle is dangerous. In hot
weather, temperatures inside a vehicle
can become high enough to cause
brain damage or even death.
Do not leave the key in your vehicle
with children and keep them in a
place where your children will not
find or play with them:
Leaving children in a vehicle with the
key is dangerous. This could result in
someone being badly injured or even
killed.
Keep all doors locked when driving:
Unlocked doors in a moving vehicle
are dangerous. Passengers can fall out
if a door is accidentally opened and
can more easily be thrown out in an
accident.
Always close all the windows and
panorama sunroof, lock the doors,
fuel-filler lid, and liftgate and take the
key with you when leaving your
vehicle unattended:
Leaving your vehicle unlocked is
dangerous as children could lock
themselves in a hot vehicle, which
could result in death. Also, a vehicle
left unlocked becomes an easy target
for thieves and intruders.
After closing the doors and the
liftgate, always verify that they are
securely closed:
Doors and the liftgate not securely
closed are dangerous, if the vehicle is
driven with a door and the liftgate not
securely closed, the door and the
liftgate could open unexpectedly
resulting in an accident.
Always confirm the safety around the
vehicle before opening a door and the
liftgate:
Suddenly opening a door and the
liftgate is dangerous. A passing vehicle
or a pedestrian could be hit and cause
an accident.
CAUTION

Always confirm the conditions
around the vehicle before opening/
closing the doors and the liftgate and
use caution during strong winds or
when parked on an incline. Not
being aware of the conditions
around the vehicle is dangerous
because fingers could get caught in
the door and the liftgate or a passing
pedestrian could be hit, resulting in
an unexpected accident or injury.
NOTE
Always stop the engine and lock the
doors. In addition, to prevent theft of
valuables, do not leave them inside
the cabin.
If the key is left in the following areas
