Theft-Deterrent System*
If the theft-deterrent system detects an
inappropriate entry into the vehicle, which
could result in the vehicle or its contents

warning lights.

The system will not function unless it's
properly armed. So when you leave the

Hazardous Driving
WARNING
Be extremely careful if it is necessary to
downshift on slippery surfaces:
Downshifting into lower gear while driving
on slippery surfaces is dangerous. The
sudden change in tire speed could cause
the tires to skid. This could lead to loss of
vehicle control and an accident.
When driving on ice or in water, snow,
mud, sand, or similar hazards:
Be cautious and allow extra distance for
braking.
Avoid sudden braking and sudden
maneuvering.
Do not pump the brakes. Continue to
press down on the brake pedal.
Refer to Antilock Brake System (ABS)
on page 4-66.
If you get stuck, select a lower gear and
accelerate slowly. Do not spin the rear
wheels.
For more traction in starting on slippery
surfaces such as ice or packed snow, use
sand, rock salt, chains, carpeting, or
other nonslip material under the rear
wheels.
NOTE
Use snow chains only on the rear wheels.
Floor Mat
We recommend the use of Genuine
Mazda floor mats.
WA R N I N G
Make sure the floor mats are hooked on the
retention pins to prevent them from
bunching up under the foot pedals:
Using a floor mat that is not secured is
dangerous as it will interfere with the
accelerator and brake pedal operation,
which could result in an accident.
Do not install two floor mats, one on top of
the other, on the driver's side:
Installing two floor mats, one on top of the
other, on the driver's side is dangerous as
the retention pins can only keep one floor
mat from sliding forward.
Loose floor mat(s) will interfere with the
foot pedals and could result in an accident.
If using an all-weather mat for winter use
always remove the original floor mat.
When setting a floor mat, position the
floor mat so that its grommets are inserted
over the pointed end of the retention posts.

Driving Tips

MX-5_8JS9-EA-20K_Edition1_old 2020-8-28 13:50:01

Never use warm or hot water for
removing snow or ice from windows and
mirrors as it could result in the glass
cracking.
Drive slowly. Braking performance can
be adversely affected if snow or ice
adheres to the brake components. If this
situation occurs, drive the vehicle
slowly, releasing the accelerator pedal
and lightly applying the brakes several
times until the brake performance
returns to normal.
▼Snow Tires
Use snow tires on all 4 wheels
Do not go faster than 120 km/h (75 mph)
while driving with sno
w tires. Inflate snow
tires 30 kPa (0.3 kgf/cm
2, 4.3 psi) more
than recommended on the tire pressure
label (driver's door frame), but never more
than the maximum c old-tire pressure
shown on the tires.

The vehicle is originally equipped with
summer tires designed for optimum
traction on wet and dry roads. If your
vehicle is to be used on snow and ice
covered roads, Mazda recommends that
you replace the tires originally equipped
on your vehicle with snow tires during the
winter months.
WARNING
Use only the same size and type tires (snow,
radial, or non-radial) on all 4 wheels:
Using tires different in size or type is
dangerous. Your vehi cle's handling could
be greatly affected and result in an
accident.
CAUTION
Check local regulations before using
studded tires.
NOTE
The tire pressure monitoring system may
not function correctly when using tires
with steel wire reinforcement in the
sidewalls (page 4-116).
▼ Tire Chains
Check local regulati
ons before using tire
chains.
CAUTION
 Chains may affect handling.
 Do not go faster than 50 km/h (30 mph)
or the chain manufacturer's
recommended limit, whichever is lower.
 Drive carefully and avoid bumps, holes,
and sharp turns.
 Avoid locked-wheel braking.
 Do not use chains on roads that are free
of snow or ice. The tires and chains could
be damaged.
 Chains may scratch or chip aluminum
wheels.
NOTE
The tire pressure monitoring system may
not function correctly when using tire
chains.
Install the chains on the rear tires only.
Do not use chains on the front tires.
Please consult an Authorized Mazda
Dealer.

Overloading
WARNING
Be careful not to overload your vehicle:
The gross axle weight rating (GAWR) and
the gross vehicle weight rating (GVWR) of
the vehicle are on the Motor Vehicle Safety
Standard Label on the driver's door frame.
Exceeding these ratings can cause an
accident or vehicle damage. You can
estimate the weight of the load by
weighing the items (or people) before
putting them in the vehicle.

Starting the Engine
WA R N I N G
Radio waves from the key may affect
medical devices such as pacemakers:
Before using the key near people who use
medical devices, ask the medical device
manufacturer or your physician if radio
