2017 MAZDA MX5 MIATA torque spec

4 –67 When Driving
ABS/TCS/DSC
Dynamic Stability
Control (DSC) The Dynamic Stability Control (DSC)
automatically controls braking and engine
torque in conjunction with systems such
as ABS and TCS to help control side slip
when driving on slippery surfaces, or
during sudden or evasive maneuvering,
enhancing vehicle safety.
Refer to ABS (page 4-65 ) and TCS
(page 4-66 ).
DSC operation is possible at speeds
greater than 20 km/h (12 mph).
The warning light turns on when the
system has a malfunction.
Refer to Warning Indication/Warning
Lights on page 4-26 .
WARNING Do not rely on the Dynamic Stability
Control as a substitute for safe driving:
The Dynamic Stability Control (DSC)
cannot compensate for unsafe and
reckless driving, excessive speed,
tailgating (following another vehicle
too closely), and hydroplaning
(reduced tire friction and road contact
because of water on the road surface).
You can still have an accident. CAUTION 
The DSC may not operate correctly
unless the following are observed: 
Use tires of the correct size specified
for your Mazda on all four wheels. 
Use tires of the same manufacturer,
brand and tread pattern on all four
wheels. 
Do not mix worn tires. 
The DSC may not operate correctly when
tire chains are used or a temporary spare
tire is installed because the tire diameter
changes.
TCS/DSC Indicator Light
This indicator light stays on for a few
seconds when the ignition is switched
ON. If the TCS or DSC is operating, the
indicator light flashes.
If the light stays on, the TCS, DSC
or the brake assist system may have a
malfunction and they may not operate
correctly. Take your vehicle to an
Authorized Mazda Dealer.

7 –20 If Trouble Arises
Flat Tire To install the antitheft lug nut
1. Place the special key on top of the nut,
and be sure to hold the key square to
it. If you hold the key at an angle, you
may damage both key and nut. Do not
use a power impact wrench.
2. Place the lug wrench on top of the
special key, apply pressure, and turn it
clockwise. Nut tightening torque
N·m (kgf·m, ft·lbf) 108—147
(12—14, 80—108)
Mounting the Tire1. Remove dirt and grime from the
mounting surfaces of the wheel and
hub, including the hub bolts, with a
cloth.
WARNING Make sure the mounting surfaces of
the wheel, hub and lug nuts are clean
before changing or replacing tires:
When changing or replacing a tire,
not removing dirt and grime from the
mounting surfaces of the wheel, hub
and hub bolts is dangerous. The lug
nuts could loosen while driving and
cause the tire to come off, resulting in
an accident.
2. Mount the tire.
3. Install the lug nuts with the beveled
edge inward; tighten them by hand.

WARNING Do not apply oil or grease to lug nuts
and bolts and do not tighten the
lug nuts beyond the recommended
tightening torque:
Applying oil or grease to lug nuts and
bolts is dangerous. The lug nuts could
loosen while driving and cause the tire
to come off, resulting in an accident.
In addition, lug nuts and bolts could
be damaged if tightened more than
necessary.

7 –21 If Trouble Arises
Flat Tire4. Turn the lug wrench counterclockwise
and lower the vehicle. Use the lug
wrench to tighten the nuts in the order
shown.

If you are unsure of how tight the nuts
should be, have them inspected at an
Authorized Mazda Dealer. Nut tightening torque
N·m (kgf·m, ft·lbf) 108—147
(12—14, 80—108) WARNING Always securely and correctly tighten
the lug nuts:
Improperly or loosely tightened lug
nuts are dangerous. The wheel could
wobble or come off. This could result
in loss of vehicle control and cause a
serious accident.
Be sure to reinstall the same nuts you
removed or replace them with metric
nuts of the same configuration:
Because the wheel studs and lug nuts
on your Mazda have metric threads,
using a non-metric nut is dangerous.
On a metric stud, it would not secure
the wheel and would damage the stud,
which could cause the wheel to slip off
and cause an accident.
5. Remove the tire blocks and store the
tools and jack.
6. Check the inflation pressure. Refer to
Tires on page 9-8 .
NOTE
(With tire pressure monitoring system)
Do not press the tire pressure monitoring
system set switch after installing the spare
tire. The switch is only to be pressed after
installing the repaired flat tire or installing
a replacement tire (page 4-18 ).
