WARNING
Do not replace the xenon fusion bulbs
yourself:
Replacing the xenon fusion bulbs
yourself is dangerous. Because the
xenon fusion bulbs require high
voltage, you could receive an electric
shock if the bulbs are handled
incorrectly. Consult an expert repairer,
we recommend an Authorised Mazda
Repairer when the replacement is
necessary.
Never touch the glass portion of a
halogen bulb with your bare hands
and always wear eye protection when
handling or working around the bulbs:
When a halogen bulb breaks, it is
dangerous. These bulbs contain
pressurised gas. If one is broken, it will
explode and serious injuries could be
caused by the fl ying glass.
If the glass portion is touched with bare
hands, body oil could cause the bulb to
overheat and explode when lit.
Always keep halogen bulbs out of the
reach of children:
Playing with a halogen bulb is
dangerous. Serious injuries could be
caused by dropping a halogen bulb or
breaking it some other way.
NOTE
  To replace the bulb, contact an
expert repairer, we recommend an
Authorised Mazda Repairer.
  If the halogen bulb is accidentally
touched, it should be cleaned with
rubbing alcohol before being used.
  Use the protective cover and carton
for the replacement bulb to dispose
of the old bulb promptly and out of
the reach of children.

Washing
CAUTION
  When the wiper lever is in the
position and the ignition is switched
ON, the wipers may move
automatically in the following cases:
 


 If the windscreen above the rain
sensor is touched or wiped with a
cloth.
 


 If the windscreen is struck with a
hand or other object from either
outside or inside the vehicle.
  Keep hands and scrapers clear of the
windscreen when the wiper lever is
in the
position and the ignition
is switched ON as fi ngers could be
pinched or the wipers and wiper
blades damaged when the wipers
activate automatically.
 If you are going to clean the
windscreen, be sure the wipers are
turned off completely (when it is
most likely that the engine is left
running) this is particularly important
when clearing ice and snow.
 
 Do not spray water in the engine
compartment. Otherwise, it could
result in engine-starting problems or
damage to electrical parts.
  When washing and waxing the
vehicle, be careful not to apply
excessive force to any single area
of the vehicle roof or the aerial.
Otherwise, you could dent the
vehicle or damage the aerial. To help protect the fi nish from rust
and deterioration, wash your Mazda
thoroughly and frequently, at least once a
month, with lukewarm or cold water.
If the vehicle is washed improperly, the
paint surface could be scratched. Here are
some examples of how scratching could
occur.
Scratches occur on the paint surface when:
 


 The vehicle is washed without fi rst
rinsing off dirt and other foreign matter.
 


 The vehicle is washed with a rough, dry,
or dirty cloth.
 


 The vehicle is washed at a car wash that
uses brushes that are dirty or too stiff.
 


 Cleansers or wax containing abrasives
are used.
NOTE
  Mazda is not responsible for
scratches caused by automatic car
washes or improper washing.
  Scratches are more noticeable on
vehicles with darker paint fi nishes.
To minimize scratches on the vehicle's
paint fi nish:




 Rinse off any dirt or other foreign matter
using lukewarm or cold water before
washing.
 


 Use plenty of lukewarm or cold water
and a soft cloth when washing the
vehicle. Do not use a nylon cloth.
 


 Rub gently when washing or drying the
vehicle.
 


 Take your vehicle only to a car wash
that keeps its brushes well maintained.
 


 Do not use abrasive cleansers or wax
that contain abrasives.
