2020 MAZDA MODEL MX-5 MIATA RF height

Vehicle shapes which do not reflect radar waves well such as empty trailers with a low
vehicle height and sports cars.
Vehicles are shipped with the direction of the radar sensors (rear) adjusted for each
vehicle to a loaded vehicle condition so that the radar sensors (rear) detect approaching
vehicles correctly. If the direction of the radar sensors (rear) has deviated for some
reason, have the vehicle inspected at an Authorized Mazda Dealer.
For repairs or replacement of the radar sensors (rear), or bumper repairs, paintwork, and
replacement near the radar sensors, consult an Authorized Mazda Dealer.
Turn off the system while pulling a trailer or while an accessory such as a bicycle carrier
is installed to the rear of the vehicle. Otherwise, the radio waves emitted by the radar will
be blocked causing the system to not operate normally.
The radar sensors are regulated by the relevant radio wave laws of the country in which
the vehicle is driven. If the vehicle is driven abroad, authorization from the country in
which the vehicle is driven may be required.

NOTE
Tires degrade over time, even when they
are not being used on the road. It is
recommended that tires generally be
replaced when they are 6 years or older.
Heat caused by hot climates or frequent
high loading conditions can accelerate the
aging process. The period in which the tire
was manufactured (both week and year) is
indicated by a 4-digit number.
Refer to Tire Labeling on page 8-25.
▼Replacing a Wheel
WA R N I N G
Always use wheels of the correct size on
your vehicle:
Using a wrong-sized wheel is dangerous.
Braking and handling could be affected,
leading to loss of control and an accident.
CAUTION
A wrong-sized wheel may adversely
affect:
 Tire fit
 Wheel and bearing life
 Ground clearance
 Snow-chain clearance
 Speedometer calibration
 Headlight aim
 Bumper height
 Tire Pressure Monitoring System
NOTE
When replacing a wheel, make sure the
new one is the same as the original
factory wheel in diameter, rim width,
and offset (inset/outset).
For details, contact an Authorized
Mazda Dealer.

Proper tire balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tires can cause
vibration and uneven wear, such as
cupping and flat spots.

8. Do the same procedure on the other side.
9. While standing on both sides of the
vehicle, lift the rear roof to the position
it stops while keeping the height of its
left and right sides as parallel as
possible.
CAUTION
Do not let go of the rear roof on both
sides until it is fully open. The rear
roof could fall if it is released too soon
and cause injury.
 Do not attempt to forcefully lift the
rear roof. If the rear roof is forcefully
lifted without being unlocked, it
could damage vehicle parts.
 Lift the rear roof with its left and right
height as parallel as possible. If the
rear roof is lifted with the left or right
height slanted, it could deform the
link mechanism.
Closing the front roof
CAUTION
 Some steps in the procedure require
holding your body in a strained position
and if over exerted it could result in
injury.
 Do the procedure being very careful not
to get your hands and fingers caught
while closing the front roof. Otherwise,
your hands or
fingers could be injured.
 Removal of the headliner is included in
the procedure, however, never drive the
vehicle with the headliner removed.
Driving the vehicle with the headliner
removed is prohibited by law. Correctly
perform the procedure while following
the instructions.

2. Do the same procedure on the other
side.
3. Close the rear roof uniformly on both sides using two adults, one on each
side of the vehicle.
CAUTION
Close the rear roof with its left and right
positions as parallel as possible. If the
rear roof is closed with its left or right
height slanted, it could deform the link
mechanism.

Tire Labeling
Federal law requires tire manufacturers to place standardized information on the sidewall of
all tires. This inform ation identifies and describes the fundam ental characteristics of the tire
and also provides a tire identification number for safety standard certification and in case of
a recall.
