MAZDA CX90 2024 Owners Manual

Inspection and Servicing
Be careful not to hurt yourself when
inspecting your vehicle, replacing a
tire, or doing some kind of
maintenance such as changing the oil
and filter.
In particular, wear thick work gloves
such as cotton gloves when touching
areas that are difficult to see while
inspecting or working on your vehicle.
Doing inspections or procedures with
your bare hands could cause injury.

If you are unsure about any procedure
this manual describes, we strongly urge
you to have a reliable and qualified
service shop perform the work,
preferably an Authorized Mazda
Dealer.

Factory-trained Mazda technicians and
genuine Mazda parts are best for your
vehicle. Without this expertise and the
parts that have been designed and
made especially for your Mazda,
inadequate, incomplete, and
insufficient servicing may result in
problems. This could lead to vehicle
damage or an accident and injuries.

For expert advice and quality service,
consult an Authorized Mazda Dealer.

To continue warranty eligibility and to
protect your investment, it is your
responsibility to properly maintain your
vehicle according to factory
recommended schedules outlined in
this manual. As part of this you must
keep your maintenance records,
receipts, repair orders and any other
documents as evidence this
maintenance was performed. You must
present these documents, should any
warranty coverage disagreement occur.
Failure to do so can result in your
warranty being voided either in whole
or in part.

This evidence may consist of the
following:
The Mazda Scheduled Maintenance
Record, refer to the Warranty
Booklet, must be completely filled
out showing mileage, repair order
number, date for each service, and
signed by a qualified automotive
service technician who service
vehicles.
Original copies of repair orders or
other receipts that include the
mileage and date the vehicle was
serviced. Each receipt should be
signed by a qualified automotive
service technician.
For self maintenance, a statement
that you completed the maintenance
yourself, displaying mileage and the
date the work was performed. Also,
receipts for the replacement parts (fluid, filters, etc.) indicating the date
and mileage must accompany this
statement.

NOTE
If you elect to perform maintenance
yourself or have your vehicle serviced
at a location other than an Authorized
Mazda Dealer, Mazda requires that all
fluids, parts and materials must meet
Mazda standards for durability and
performance as described in this
manual.

Claims against the warranty resulting
from lack of maintenance, as opposed

Mazda workmanship, will not be
honored.

Any auto repair shop using parts
equivalent to your Mazda's original
equipment may perform maintenance.
But we recommend that it always be
done by an Authorized Mazda Dealer
using genuine Mazda parts.

Warnings and Cautionsfor Daily Inspection
WARNING
Do not perform maintenance work if
you lack sufficient knowledge and
experience or the proper tools and
equipment to do the work. Have
maintenance work done by a
qualified technician.
Performing maintenance work on a
vehicle is dangerous if not done
properly. You can be seriously injured
while performing some maintenance
procedures.
If you must run the hybrid system
while working under the hood, make
certain that you remove all jewelry
(especially rings, bracelets, watches,
and necklaces) and all neckties,
scarves, and similar loose clothing
before getting near the cooling fan
which may turn on unexpectedly.
Working under the hood with the
hybrid system operating is dangerous.
It becomes even more dangerous
when you wear jewelry, loose clothing
or have long hair or a long beard.
Either can become entangled in
moving parts and result in injury.
Pull over to a safe location, then
switch the vehicle power off and
make sure the fan is not running
before attempting to work near the
cooling fan.
Working near the cooling fan when it is
running is dangerous. The fan could
continue running indefinitely even if
the engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.
Do not leave items in the motor
compartment.
After you have finished checking or
doing servicing in the engine
compartment, do not forget and leave
items such as tools or rags in the motor
compartment. Tools or other items left
in the engine compartment could
cause the hybrid system damage or a
fire leading to an unexpected accident.
CAUTION
When using a chassis roller, turn the
following systems off to prevent them
from mis-operating while the vehicle is
running on the chassis roller.
 Mazda Radar Cruise Control
(MRCC)
 Mazda Radar Cruise Control with
Stop & Go function (MRCC with
