Gasoline MAZDA MX5 MIATA 2023 Owners Manual

Fuel and Engine Exhaust Precautions
▼Fuel Requirements
Vehicles with catalytic converters or oxygen sensors must use ONLY UNLEADED FUEL,
which will reduce exhaust emissions a
nd keep spark plug fouling to a minimum.

To achieve maximum engine performance, use the specified fuel.
Fuel Octane Rating*1 (Anti-knock index)
Premium unleaded fuel 91 [(R+M)/2 method] or above (96 RON or above)
*1 U.S. federal law requires that octane ratings be posted on gas station pumps.
Regular unleaded fuel with an octane rating from 87 to 90 (91 to 95 RON) can be used, but
this will reduce performance slightly, such as reduced engine output, and engine knocking.
Fuel with a rating lower than 87 octane (91 RON) will negatively affect the emission control
system performance and could also cause en gine knocking and serious engine damage.
CAUTION
USE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic co nverter and oxygen sensors and will lead to
deterioration of the emission control system and or failures.
 This vehicle can only use oxygenated fuels containing no more than 10 % ethanol by
volume. Damage to the vehicle may occur when ethanol exceeds this recommendation, or
if the gasoline contains any methanol. Stop using gasohol of any kind if your vehicle engine
is performing poorly.
 Never add fuel system additives other than a Mazda genuine product, otherwise the
emission control system could be damaged. Consult an Authorized Mazda Dealer for
details.
Gasoline blended with oxygenates such as alcohol or ether compounds are generally
referred to as oxygenated fuels. The common gasoline blend that can be used with your
vehicle is ethanol blended at no more than 10 %. Gasoline containing alcohol, such as
ethanol or methanol, may be marketed under the name "Gasohol".

Vehicle damage and drivability problems resu lting from the use of the following may not be
covered by the warranty.
Gasohol containing more than 10 % ethanol.
Gasoline or gasohol containing methanol.
Leaded fuel or leaded gasohol.

Body Lubrication
All moving points of the body, such as
door and hood hinges and locks, should be
lubricated each time the engine oil is
changed. Use a nonfreezing lubricant on
locks during cold weather.

Make sure the hood's secondary latch
keeps the hood from opening when the
primary latch is released.
Wiper Blades
CAUTION
Hot waxes applied by automatic car
washers have been known to affect the
wiper's ability to clean windows.
 To prevent damage to the wiper blades,
do not use gasoline, kerosene, paint
thinner, or other solvents on or near
them.
 When the wiper lever is in the AUTO
position and the ignition is switched ON,
the wipers may move automatically in
the following cases:
 If the windshield above the rain sensor
is touched.
 If the windshield above the rain sensor
is wiped with a cloth.
 If the windshield is struck with a hand
or other object.
 If the rain sensor is struck with a hand
or other object from inside the vehicle.
Be careful not to pinch hands or fingers
as it may cause injury, or damage the
wipers. When washing or servicing the
vehicle, make sure the wiper lever is in
the OFF position.
Contamination of either the windshield or
the blades with foreign matter can reduce
wiper effectiveness. Common sources are
insects, tree sap, and hot wax treatments
used by some commercial car washes.

If the blades are not wiping properly, clean
the window and blades with a good
cleaner or mild detergent; then rinse
thoroughly with clean water. Repeat if
necessary.

Do not spray water directly on the seam
area of the body and the convertible top
as it could result in water penetrating the
cabin and trunk.
Some leather treatment products can
ruin the convertible top's gloss. Be careful
of the one you choose.
 Test on an inconspicuous, small corner of
the convertible top if you are not sure.
 Do not wipe the convertible top using
alcohol, chlorine bleach, or organic
solvents such as thinner, benzene, or
gasoline. Otherwise, they may cause
discoloration or stains.
 Do not get any car wax on the
convertible top.
If you do, remove it with a good leather
cleaner or mild detergent (about 5%
solution).
 Too much treatment on the convertible
top can be as damaging as too little.
Follow the manufacturer's directions.
Do not overdo it!
 Let the convertible top dry completely
before lowering after applying treatment
or dressing.

10. Remove your finger from theretractable hardtop switch after the rear
roof is raised up.

11. Check if water remains in the watertrays of the drain covers through the
gap between the rear roof and the
body.
If no water remains, the drain hose is
not clogged.
If water remains, the drain hose may
be clogged. Consult an Authorized
Mazda Dealer.

Water trays
▼ Plastic Part Maintenance
When cleaning the plastic lenses of the
lights, do not use gasoline, kerosene,
rectified spirit, paint, thinner, highly
acidic detergents, or strongly alkaline
detergents. Otherwise, these chemical
agents can discolor or damage the
surfaces resulting in a significant loss in
functionality. If plastic parts become
inadvertently exposed to any of these
chemical agents, flush with water
immediately.
If plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or fluids such as
gasoline, oil, engine coolant, or battery
fluid, it could cause discoloration,
staining, or paint peeling. Wipe off any
such chemical agents or fluids using a
soft cloth immediately.
High water temperature and high water
pressure car washers are available
depending on the type of high pressure
car washer device. If the car washer
nozzle is put too close to the vehicle or
aimed at one area for an extended period
of time, it could deform plastic parts or
damage the paint.
Do not use wax containing compounds
(polish). Otherwise, it could result in
paint damage.
In addition, do not use an electrical or
air tool to apply wax. Otherwise, the
frictional heat generated could result in
deformation of plastic parts or paint
damage.

Interior Care
WA R N I N G
Do not spray water into the vehicle cabin:
Spraying water into the vehicle cabin is
dangerous as electrical devices such as the
audio and switches could get wet resulting
in a malfunction or vehicle fire.
NOTE
Do not wipe the interior using alcohol,
chlorine bleach, or organic solvents
such as thinner, benzene, and gasoline.
Otherwise, it may cause discoloration or
stains.
Rubbing hard with a stiff brush or cloth
may cause damage.
If the vehicle interior becomes soiled by
any of the following, wipe it off
immediately using a soft cloth.
Leaving it uncleaned could cause
discoloration, stains, cracks, or peeling of
the coating, and it will make it hard to
wipe off later.
Beverage or fragrance
Grease or oil
Soiling
▼ Seat Belt Maintenance
1. Clean the soiled area by lightly
dabbing it with a soft cloth soaked in a
mild detergent (approx. 5%) diluted
with water.
2. Wipe off the remaining detergent using a cloth soaked in clean water and
wrung out well.
3. Before retracting seat belts which have
been pulled out for cleaning, dry them
off thoroughly and make sure there is
no remaining moisture on them.
WA R N I N G
If a seat belt appears frayed or has
abrasions, have it replaced by an
Authorized Mazda Dealer:
If a seat belt is used under such a condition,
it cannot function at its full capacity which
could result in serious injury or death.
Use a mild detergent to remove soiling
from a seat belt:
If organic solvents are used for cleaning the
seat belts or they become stained or
bleached, there is the possibility of them
becoming weakened and as a result, they
may not function at their full capacity
which could cause serious injury or death.
NOTE
Clean seat belts diligently if they get dirty.
Leaving them uncleaned will make it
difficult to clean them later, and it may
affect the smooth retracting of the seat
belt.
▼ Vinyl Upholstery Maintenance
Remove dust and dirt from the vinyl
upholstery using a brush or vacuum.
Remove soiling from vinyl upholstery
using a leather and vinyl upholstery
cleaner.
