engine oil MAZDA MODEL 3 HATCHBACK 2018 (in English) Owner's Manual

WA R N I N G
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
pressurized gas. If one is broken, it will
explode and serious injuries could be
caused by the flying 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.
CAUTION
When removing the lens or lamp unit using
a flathead screwdriver, make sure that the
flathead screwdriver does not contact the
interior terminal. If the flathead screwdriver
contacts the terminal, a short circuit may
occur.
NOTE
To replace the bulb, contact an
Authorized Mazda Dealer.
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.
▼Replacing Exterior Light Bulbs
Headlights (With LED headlights),
Daytime running lights/Parking lights
(With LED headlights), Fog lights*
The LED bulb cannot be replaced as a
single unit because it is an integrated unit.
The LED bulb has to be replaced with the
unit. We recommend an Authorized
Mazda Dealer when the replacement is
necessary.
Headlights (With halogen headlights)
Low-beam bulbs
1. If you are changing the right bulb, start
the engine, turn the steering wheel all
the way to the left, and turn off engine.
If you are changing the left bulb, turn
the steering wheel to the right, and turn
off engine.
2. Make sure the headlight switch is off.
3. Pull the center of each plastic retainer and remove the retainers.

▼Aluminum Wheel Maintenance*
A protective coating is provided over the
aluminum wheels. Special care is needed
to protect t
his coating.
CAUTION
Do not use any detergent other than mild
detergent. Before using any detergent,
verify the ingredients. Otherwise, the
product could discolor or stain the
aluminum wheels.
NOTE
Do not use a wire brush or any abrasive
cleaner, polishing compound, or solvent
on aluminum wheels. They may damage
the coating.
Always use a sponge or soft cloth to
clean the wheels.
Rinse the wheels thoroughly with
lukewarm or cold wate r. Also, be sure to
clean the wheels after driving on dusty
or salted roads to help prevent
corrosion.
Avoid washing your vehicle in an
automatic car wash that uses high-speed
or hard brushes.
▼ Plastic Part Maintenance
When cleaning the plastic lenses of the
lights, do not use gasoline, kerosene,
rectified spirit, paint, thinner, highly
acidic detergents, or strongly alkaline
detergents. Otherwise, these chemical
agents can discolor or damage the
surfaces resulting in a significant loss in
functionality. If plastic parts become
inadvertently exposed to any of these
chemical agents, flush with water
immediately.
If plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or fluids such as
gasoline, oil, engine coolant, or battery
fluid, it could cause discoloration,
staining, or paint peeling. Wipe off any
such chemical agents
or fluids using a
soft cloth immediately.
High water temperature and high water
pressure car washers are available
depending on the type of high pressure
car washer device. If the car washer
nozzle is put too close to the vehicle or
aimed at one area for an extended period
of time, it could deform plastic parts or
damage the paint.
Do not use wax containing compounds
(polish). Otherwise, it could result in
paint damage.
In addition, do not use an electrical or
air tool to apply wax. Otherwise, the
frictional heat generated could result in
deformation of plast ic parts or paint
damage.
