Active Driving Display
Maintenance *
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 chemical solvent gets on
the active driving display, wipe it off
immediately. The dust-proof sheet could
be damaged and the surface coating could
be scratched. Use a fi ne, soft cloth such as
those used for cleaning eyeglasses.
NOTE
Use of compressed air when cleaning the
dust-proof sheet is recommended.

Cleaning the Window Interiors
If the windows become covered with an
oily, greasy, or waxy fi lm, clean them with
glass cleaner. Follow the directions on the
container.
CAUTION
 


 Do not scrape or scratch the inside of
the window glass. It could damage the
thermal fi laments and the antenna lines.
 


 When washing the inside of the window
glass, use a soft cloth dampened in
lukewarm water, gently wiping the
thermal fi laments and the antenna lines.
  Use of glass cleaning products could
damage the thermal fi laments and the
antenna lines.

Cleaning the Floor Mats
Rubber fl oor mats should be cleaned with
mild soap and water only.
WARNING
Do not use rubber cleaners, such as tire
cleaner or tire shine, when cleaning
rubber fl oor mats:
Cleaning the rubber fl oor mats with
rubber cleaning products makes the
fl oor 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 fl oor mats for cleaning,
always reinstall them securely (page




 The vehicle begins to vibrate
excessively.
 

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.

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.

4. Turn the lug wrench counterclockwise
and lower the vehicle. 5. Use the lug wrench to tighten the nuts
in the order shown.



If you are unsure of how tight the nuts

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 confi guration:
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.
