collision detection)
This system automatically unlocks the
doors, fuel-filler lid, and liftgate in the
event the vehicle is involved in an
accident to allow passengers to get out
of the vehicle immediately and prevent

is switched ON and in the event the
vehicle receives an impact strong
enough to inflate the air bags, all the
doors, fuel-filler lid, and liftgate are
automatically unlocked after about 6
seconds have elapsed from the time of
the accident.
The doors, fuel-filler lid, and liftgate
may not unlock depending on how an
impact is applied, the force of the
impact, and other conditions of the
accident.
If door-related systems or the battery is
malfunctioning, the doors, fuel-filler lid,
and liftgate will not unlock.

Maintenance
Always keep the jack clean.
Make sure the moving parts are kept
free from dirt or rust.
Make sure the screw thread is
adequately lubricated.
▼Spare Tire
Your Mazda has a temporary spare tire.
The temporary spare tire is lighter and
smaller than a conventional tire, and is
designed only for emergency use and
should be used only for VERY short
periods. Temporary spare tires should
NEVER be used for long drives or
extended periods.
WA R N I N G
Do not install the temporary spare tire on
the front wheels (driving wheels):
Driving with the temporary spare tire on
one of the front driving wheels is
dangerous. Handling will be
affected. You
could lose control of the vehicle, especially
on ice or snow bound roads, and have an
accident. Move a regular tire to the front
wheel and install the temporary spare tire
to the rear.
CAUTION
 When using the temporary spare tire,
driving stability may decrease compared
to when using only the conventional tire.
Drive carefully.
To avoid damage to the temporary spare
tire or to the vehicle, observe the
following precautions:
 Do not exceed 80 km/h (50 mph).
 Avoid driving over obstacles. Also, do
not drive through an automatic car
wash. This tire's diameter is smaller
than a conventional tire, so the ground
clearance is reduced.
 Do not use a tire chain on this tire
because it will not
fit properly.
 Do not use your temporary spare tire
on any other vehicle, it has been
designed only for your Mazda.
 Use only one temporary spare tire on
your vehicle at the same time.
To remove the spare tire

1. Remove the trunk mat.

NOTE
When raising the jack head into the
jacking position and aligning the
groove in the jack head with the rail
under the vehicle body, the top of the
jack head contacts the vehicle's
underbody without the rail contacting
the bottom of the groove.
7. Insert the jack lever and attach the lug wrench to tire jack.

8. Turn the jack handle clockwise and
raise the vehicle high enough so that
the spare tire can be installed. Before
removing the lug nuts, make sure your
Mazda is firmly in position and that it
cannot slip or move.

WA R N I N G
Do not jack up the vehicle higher than
is necessary:
Jacking up the vehicle higher than is
necessary is dangerous as it could
destabilize the vehicle resulting in an
accident.
Do not start the engine or shake the
vehicle while it is jacked up:
Starting the engine or shaking the
vehicle while it is jacked up is
dangerous as it could cause the vehicle
to fall off the jack resulting in an
accident.
Never go under the vehicle while it is
jacked up:
Going under the vehicle while it is
jacked up is dangerous as it could result
in death or serious injury if the vehicle
were to fall off the jack.
9. Remove the lug nuts by turning them counterclockwise; then remove the
wheel and center cap.
▼Locking Lug Nuts
If your Mazda is equipped with the
optional antitheft wheel lug nuts, a special
key must be used to unlock the locking lug
nut for each wheel. The key is stored in
the glove compartment, center console
storage, storage box, o
r trunk. Register the
key and lug nuts with the lock
manufacturer by filling out the registration
card and mailing it in using the
accompanying envelope. If the key is lost,
consult an Authorized Mazda Dealer or
use the lock manufacturer’s order form to
order a new key.
