▼Panel Maintenance
If a panel becomes so
iled, wipe it off with
a soft cloth soaked in clean water and
thoroughly wrung out.
If some areas require further cleaning, use
the following procedure:
1. Wipe the soiled area with a soft cloth
soaked in a mild detergent (approx.
5 %) diluted with water.
2. Wipe off the remaining detergent using a cloth soaked in clean water and
wrung out well.

The dust-proof sheet has a coating. When
cleaning, do not use a hard or
rough-surface cloth, or cleaning detergent.
In addition, if a chemi
cal solvent gets on
the active driving di splay, wipe it off
immediately. The dust-proof sheet could
be damaged and the surface coating could
be scratched. Use a fin e, soft cloth such as
those used for cleaning eyeglasses.

If the windows become covered with an
oily, greasy, or waxy film, clean them with
glass cleaner. Follow th
e directions on the
container.
CAUTION
 Do not scrape or scratch the inside of the
window glass. It could damage the
thermal
filaments and the antenna lines.
 When washing the inside of the window
glass, use a soft cloth dampened in
lukewarm water, gently wiping the
thermal filaments and the antenna lines.
Use of glass cleaning products could
damage the thermal filaments and the
antenna lines.
▼ Cleaning the Floor Mats
Rubber floor mats should be cleaned with
mild soap and water only.
WA R N I N G
Do not use rubber cleaners, such as tire
cleaner or tire shine, when cleaning rubber
floor
mats:
Cleaning the rubber floor mats with rubber
cleaning products makes the floor mats
slippery.
This may cause an accident when
depressing the accelerator or brake pedal
or when getting in or out of the vehicle.
After removing the floor mats for
cleaning, always rein stall them securely
(page 3-49).

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

Nut tightening torque
N·m (kgf·m, ft·lbf) 108―147 (12―14,
80―108)
WA R N I N G
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.
6. (Vehicles with sub-woofer)
