▼Replacing a Wheel
WARNING
Always use wheels of the correct size
on your vehicle:
Using a wrong-sized wheel is
dangerous. Braking and handling could
be a
ffected, leading to loss of control
and an accident.
CAUTION
A wrong-sized wheel may adversely
a ff ect:
 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 o ffset (inset/outset).

using that system and consult an
Authorized Mazda Dealer as soon as
possible.

Mazda3_8JM2-EA -20H_Edition1_new 2020-7-10 17:21:34

Pay special attention to removing salt,
dirt, mud, and other foreign material
from the underside of the fenders, and
make sure the drain holes in the lower
edges of the doors and rocker panels
are clean.

Insects, tar, tree sap, bird droppings,
industrial fallout, and similar deposits
can damage the finish if not removed
immediately. When prompt washing
with plain water is ineffective, use a
mild soap made for use on vehicles.

Thoroughly rinse o ff all soap with
lukewarm or cold water. Do not allow
soap to dry on the finish.

After washing the vehicle, dry it with a
clean chamois to prevent water spots
from forming.
WARNING
Dry o ff brakes that have become wet
by driving slowly, releasing the
accelerator pedal and lightly applying
the brakes several times until the
brake performance returns to normal:
Driving with wet brakes is dangerous.
Increased stopping distance or the
vehicle pulling to one side when
braking could result in a serious
accident. Light braking will indicate
whether the brakes have been
a ff ected.
When using an automatic car wash
Retract the door mirrors.The automatic car wash brushes
could reduce the paint lustre or
hasten paint deterioration.
When using a high water pressure car
wash
High water temperature and high
water pressure car washers are
available depending on the type of car
wash machine. If the car washer nozzle
is put too close to the vehicle, the
force of the spray could damage or
deform the molding , aff ect the
sealability of parts, and allow water to
penetrate the interior. Keep a su fficient
space (30 cm (12 in) or more)
between the nozzle and the vehicle. In
addition, do not spend too much time
spraying the same area of the vehicle,
and be very careful when spraying
between gaps in doors and around
windows.
Waxing
Your vehicle needs to be waxed when
water no longer beads on the finish.
Always wash and dry the vehicle before
waxing it. In addition to the vehicle
body, wax the metal trim to maintain
its luster.

1. Use wax which contains no abrasives.
Wax containing abrasives will
remove paints and could damage
bright metal parts.
2. Use a good grade of natural wax for metallic, mica, and solid colors.
3. When waxing, coat evenly with the sponge supplied or a soft cloth.
4. Wipe o ff the wax with a soft cloth.
NOTE
A spot remover to remove oil, tar, and
similar materials will usually also take
o ff the wax. Rewax these areas even if
the rest of the vehicle does not need it.
