Rocking the Vehicle
WA R N I N G
Do not spin the wheels at more than 56
km/h (35 mph), and do not allow anyone
to stand behind a wheel when pushing the
vehicle:
When the vehicle is stuck, spinning the
wheels at high speed is dangerous. The
spinning tire could overheat and explode.
This could cause serious injuries.
CAUTION
Too much rocking may cause engine
overheating, transaxle failure, and tire
damage.
If you must rock the vehicle to free it from
snow, sand or mud, depress the accelerator
slightly and slowly move the shift lever/
selector lever from 1 (D) to R position.
Winter Driving
Carry emergency gear, including tire
chains, window scraper, flares, a small
shovel, jumper cables, and a small bag of
sand or salt.
Ask an Authorized Mazda Dealer to check
the following:
Have the proper ratio of antifreeze in the
radiator.
Refer to Engine Coolant on page 6-25.
Inspect the battery and its cables. Cold
reduces battery capacity.
Use an engine oil appropriate for the
lowest ambient temperatures that the
vehicle will be driven in (page 6-22).
Inspect the ignition system for damage
and loose connections.
Use washer fluid made with
antifreeze ―but do not use engine
coolant antifreeze for washer fluid (page
6-27).
NOTE
Remove snow before driving. Snow left
on the windshield is dangerous as it
could obstruct vision.
Do not apply excessive force to a
window scraper when removing ice or
frozen snow on the mirror glass and
windshield.
Never use warm or hot water for
removing snow or ice from windows and
mirrors as it could result in the glass
cracking.

MIN OK
5. Pull it out again and examine the level.
The level is normal if it is between the
MIN and MAX marks.
If it is near or below MIN, add enough
oil to bring the level to MAX.
CAUTION
Do not overfill the engine oil. This may
cause engine damage.
6. Make sure the O-ring on the dipstick is positioned properly before reinserting
the dipstick.
7. Reinsert the dipstick fully.
Engine Coolant
▼ Inspecting Coolant Level
WA R N I N G
Do not use a match or live flame in the
engine compartment. DO NOT ADD
COOLANT WHEN THE ENGINE IS HOT:
A hot engine is dangerous. If the engine has
been running, parts of the engine
compartment can become very hot. You
could be burned. Carefully inspect the
engine coolant in the coolant reservoir, but
do not open it.
Pull over to a safe location, then switch
the ignition off and make sure the fan is
not running before attempting to work
near the cooling fan:
Working near the cooling fan when it is
running is dangerous. The fan could
continue running indefinitely even if the
engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.
Do not remove either cooling
system cap when the engine and radiator
are hot:
When the engine and radiator are hot,
scalding coolant and steam may shoot out
under pressure and cause serious injury.

plain water is ineffective, use a mild soap
made for use on vehicles.

Thoroughly rinse off 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.
WA R N I N G
Dry off 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
affected.
When using an automatic car wash
Retract the door mirrors.
The automatic car wa sh 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, affect the sealability of parts, and
allow water to penetrate the interior. Keep
a sufficient 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.
Wa x i n g
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 off the wax with a soft cloth.
NOTE
A spot remover to remove oil, tar, and
similar materials will usually also take off
the wax. Rewax these areas even if the rest
of the vehicle does not need it.
▼ Repairing Damage to the Finish
Deep scratches or chips on the finish
should be repaired promptly. Exposed
metal quickly rusts an
d can lead to major
repairs.

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 water. 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.
(18-inch wheel vehicle)
If your aluminum wheels lose luster,
apply wax which contains no polishing
powder.
▼ 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 plastic parts or paint
damage.

4. Remove moisture with a dry, soft cloth and allow the leather to further dry in a
well-ventilated, shaded area. If the
leather gets wet such as from rain,
remove the moisture and dry it as soon
as possible.
NOTE
Because genuine leather is a natural
material, its surface is not uniform and
it may have natural scars, scratches,
and wrinkles.
To maintain the quality for as long as
possible, periodical maintenance, about
twice a year, is recommended.
If the leather upholstery comes into
contact with any of the following, clean
it immediately.
Leaving it uncleaned could cause
premature wear, mold, or stains.
Sand or dirt
Grease or oil, such as hand cream
Alcohol, such as in cosmetic or hair
dressing items
If the leather upholstery gets wet,
promptly remove moisture with a dry
cloth. Remaining moisture on the
surface may cause deterioration such as
hardening and shrinkage.
Exposure to direct sunlight for long
periods may cause deterioration and
shrinkage. When parking the car under
direct sunlight for long periods, shade
the interior using sunshades.
Do not leave vinyl products on the
leather upholstery for long periods.
They may affect the leather quality and
coloring. If the cabin temperature
becomes hot, the vinyl may deteriorate
and adhere to the genuine leather.
▼Plastic Part Maintenance
CAUTION
Do not use polishing agents.
Depending on the product ingredients,
they could cause discoloration, stains,
cracks or peeling of the coating.
