CAUTION
¾Before pulling out the compressor
plug from the electrical socket,
make sure the compressor power
switch is
off.
¾The compressor turns on and off
with the push-button switch.
15.Turn the compressor switch on and
inflate the tyre carefully to the
correct inflation pressure.
WARNING
Never operate the compressor
above 300 kPa (3.1 kgf/cm2, 3
bar, 43.5 psi):
Operating the compressor above
300 kPa (3.1 kgf/cm
2, 3 bar, 43.5
psi) is dangerous. When the
inflation pressure rises above 300
kPa (3.1 kgf/cm
2, 3 bar, 43.5 psi),
heated air will be exhausted from
the back of the compressor and you
could be burned.
NOTE
xCheck the tyre inflation pressure
label (driver's door frame) for the
correct tyre inflation pressure.
xDo not use the compressor for
longer than 10 minutes because
using the compressor for long
periods could damage it.
If Trouble Arises
Flat Tyre

xIf the tyre does not inflate, repair
of the tyre may not be possible. If
the tyre does not reach the
correct inflation pressure within a
10-minute period, it probably has
received more extensive damage.
When this happens, the
emergency flat tyre repair kit
cannot be used to repair the tyre.
Contact an expert repairer (we
recommend an Authorised
Mazda Repairer).
xIf the tyre has been over-inflated,
loosen the screw cap on the
compressor and bleed some of
the air out.
16.When the tyre has been inflated to
the proper inflation pressure, turn
the compressor switch off and
remove the compressor hose from
the tyre valve.
17.Install the tyre valve cap.
18.Put the emergency flat tyre repair
kit in the luggage compartment and
continue driving.
CAUTION
¾Drive carefully to an expert
repairer (we recommend an
Authorised Mazda Repairer) and
keep the vehicle speed below 80
km/h (50 mph).
¾If the vehicle is driven 80 km/h
(50 mph) or higher, the vehicle
might begin to vibrate.
NOTE
If the tyre is not properly inflated,
the tyre pressure monitoring system
warning light will illuminate (page
7-60).
19.After driving the vehicle for 10
minutes or 5 km (3 miles), check
the tyre pressure with the tyre
pressure gauge equipped with the
compressor. If the tyre pressure has
fallen below the correct tyre
pressure, inflate the tyre to the
correct pressure again following the
steps from number 14.
CAUTION
¾If the tyre
inflation pressure falls
below 130 kPa (1.3 kgf/cm2 or
bar, 18.9 psi), repair cannot be
done with the repair kit. Park the
vehicle on a level surface off the
right-of-way and contact an
expert repairer (we recommend
an Authorised Mazda Repairer).
¾If the tyre inflation pressure
continues to remain low after
repeating steps 13 to 20, park the
vehicle on a level surface
off the
right-of-way and contact an
expert repairer (we recommend
an Authorised Mazda Repairer).
NOTE
When checking the tyre inflation
pressure with the tyre pressure
gauge on the compressor unit,
make sure the compressor switch is
turned off.
20.The emergency flat tyre repair is
completed if the tyre air pressure
does not decrease. Drive the
vehicle carefully to the nearest
expert repairer (we recommend an
Authorised Mazda Repairer)
promptly and have the tyre
replaced. Mazda recommends that
the tyre be replaced with a new
one. If the tyre is to be repaired and
reused, consult an expert repairer
(we recommend an Authorised
Mazda Repairer).
Peel off the speed restriction sticker
after replacing the tyre.

CAUTION
¾For a tyre which has undergone
an emergency flat tyre repair
using the emergency flat tyre
repair kit, Mazda recommends
that the tyre be replaced with a
new one as soon as possible. If
the tyre is to be repaired and
reused, consult an expert repairer
(we recommend an Authorised
Mazda Repairer).
¾The wheel can be reused after
any sealant adhering to it is
wiped off and carefully inspected.
However, replace the tyre valve
with a new one.
▼Inspecting the Emergency Flat Tyre
Repair Kit
Inspect the emergency flat tyre repair
kit at regular intervals.
xCheck the tyre sealant period of
effective use.
xCheck the operation of the tyre
compressor.
NOTE
The tyre sealant has a period of
effective use. Check the period of
effective use indicated on the bottle
label and do not use it if it has expired.
Have the tyre sealant replaced at an
expert repairer (we recommend an
Authorised Mazda Repairer) before the
period of
effective use has expired.
Changing a Flat Tyre
(With Spare Tyre)
▼Changing a Flat Tyre
NOTE
If the following occurs while driving , it
could indicate a flat tyre.
xSteering becomes difficult.xThe vehicle begins to vibrate
excessively.
xThe vehicle pulls in one direction.
If you have a flat tyre, drive slowly to a
level spot that is well
off the road and
out of the way of traffic to change the
tyre.
Stopping in traffic or on the shoulder
of a busy road is dangerous.
WARNING
Be sure to follow the directions for
changing a tyre:
Changing a tyre is dangerous if not
done properly. The vehicle can slip off
the jack and seriously injure someone.
No person should place any portion of
their body under a vehicle that is
supported by a jack.
Never allow anyone inside a vehicle
supported by a jack:
Allowing someone to remain in a
vehicle supported by a jack is
dangerous. The occupant could cause
the vehicle to fall resulting in serious
injury.
NOTE
Make sure the jack is well lubricated
before using it.
1. Park on a hard, level surface off the
right-of-way and
firmly set the
parking brake.
If Trouble Arises
Flat Tyre
7-33

2. Put a vehicle with an automatic
transmission in Park (P), a manual
transmission in Reverse (R) or 1,
and turn off the engine.
3. Turn on the hazard warning flasher.
4. Have passengers get out of the
vehicle and away from the vehicle
and traffic.
5. Remove any luggage, the jack,
tools, and spare tyre (page 7-24).
6. Block the wheel diagonally
opposite the flat tyre. When
blocking a wheel, place a tyre block
both in front and behind the tyre.
NOTE
When blocking a tyre, use rocks or
wood blocks of sufficient size if
possible to hold the tyre in place.
▼Removing a Flat Tyre
WARNING
When jacking-up a vehicle, always
shift the shift lever to 1st or R position
(manual transmission vehicle) or shift
the selector lever to P position
(automatic transmission vehicle),
apply the parking brake, and place
wheel blocks in the position
diagonally opposed to the jack:
Changing a flat tyre without using
wheel blocks is dangerous because the
vehicle may move and fall off the jack
even with the shift lever in 1st or R
position, or the selector lever is in P
position, which could result in an
accident.
1. If your vehicle is equipped with a
wheel cover, pry off the wheel
cover with the bevelled end of the
jack lever.

NOTE
Force the end of the jack lever
firmly between wheel and cover, or
removal will be difficult.

under the jack is dangerous as it
could deform the vehicle body or
the vehicle could fall off the jack
resulting in an accident.
Use only the jack provided with
your Mazda:
Using a jack that is not designed for
your Mazda is dangerous. The
vehicle could slip off the jack and
seriously injure someone.
Never place objects under the
jack:
Jacking the vehicle with an object
under the jack is dangerous. The
jack could slip and someone could
be seriously injured by the jack or
the falling vehicle.
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
wheel brace to tyre jack.

8. Turn the jack handle clockwise and
raise the vehicle high enough so
that the spare tyre can be installed.

WARNING
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 wheel nuts by turning
them anticlockwise; then remove
the wheel and centre cap.
▼Mounting the Spare Tyre
1. 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 wheel nuts
are clean before changing or
replacing tyres:
When changing or replacing a tyre,
not removing dirt and grime from
the mounting surfaces of the wheel,
hub and hub bolts is dangerous.
The wheel nuts could loosen while
driving and cause the tyre to come
off, resulting in an accident.
2. Mount the spare tyre.
3. Install the wheel nuts with the
bevelled edge inward; tighten them
by hand.

WARNING
Do not apply oil or grease to
wheel nuts and bolts and do not
tighten the wheel nuts beyond the
recommended tightening torque:
Applying oil or grease to wheel nuts
and bolts is dangerous. The wheel
nuts could loosen while driving and
cause the tyre to come off, resulting
in an accident. In addition, wheel
nuts and bolts could be damaged if
tightened more than necessary.
4. Turn the jack handle anticlockwise
using the wheel brace and lower
the vehicle.
If Trouble Arises

nuts should be, have them
inspected at an expert repairer (we
recommend an Authorised Mazda
Repairer).
Nut tightening torque
N·m (kgf·m, ft·lbf)108Š147 (12Š14,
80Š108)
WARNING
Always securely and correctly
tighten the wheel nuts:
Improperly or loosely tightened
wheel 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 wheel
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.
6. Remove the tyre blocks and store
the tools and jack.
7. Store the damaged tyre in the
luggage compartment.
8. Check the inflation pressure. Refer
to Tyres on page 9-10.
9. Have the flat tyre repaired or
replaced as soon as possible.
WARNING
Do not drive with any tyres that have
incorrect air pressure:
Driving on tyres with incorrect air
pressure is dangerous. Tyres with
incorrect pressure could affect
handling and result in an accident.
When you check the regular tyres' air
pressure, check the spare tyre, too.
NOTE
To prevent the jack and tool from
rattling, store them properly.
