Water Marks
Occurrence
Rain, fog , dew, and even tap water can
contain harmful minerals such as salt
and lime. If moisture containing these
minerals settles on the vehicle and
evaporates, the minerals will
concentrate and harden to form white
rings. The rings can damage your
vehicle's finish.
Prevention
It is necessary to wash and wax your
vehicle to preserve its finish according
to the instructions in this section.
These steps should be taken
immediately after you find water marks
on your vehicle's finish.
Pa i n t C h i p p i n g
Occurrence
Paint chipping occurs when gravel
thrown in the air by another vehicle's
tires hits your vehicle.
How to avoid paint chipping
Keeping a safe distance between you
and the vehicle ahead reduces the
chances of having your paint chipped
by flying gravel.
NOTE
The paint chipping zone varies with
the speed of the vehicle. For
example, when traveling at 90 km/h
(56 mph), the paint chipping zone is
50 m (164 ft).
In low temperatures a vehicle's finish
hardens. This increases the chance of
paint chipping.
Chipped paint can lead to rust
forming on your Mazda. Before this
happens, repair the damage by using
Mazda touch-up paint according to
the instructions in this section.
Failure to repair the a ffected area
could lead to serious rusting and
expensive repairs.

Follow all label and container
directions when using a chemical
cleaner or polish. Read all warnings
and cautions.
▼ Maintaining the Finish
Washing
CAUTION

Before lifting the windshield wiper
blades o ff the windshield, always

When the ignition is switched ON
and the wiper lever is in the AUTO
position, do not touch the
windshield or the windshield wipers
Otherwise, the windshield wipers
will operate automatically which
could catch your fingers or damage
the windshield wipers.
When removing ice or snow, or
cleaning the windshield, always
make sure the wiper lever is in the
OFF position.
 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 antenna.
Otherwise, you could dent the
vehicle or damage the antenna.
 Make sure that the fuel- filler lid is
closed and lock the doors.
Otherwise, the fuel-filler lid may be
forcefully opened by water pressure
causing damage to the vehicle or fuel- filler lid.
To help protect the finish 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 first
rinsing o ff 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 sti ff.
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 finishes.
To minimize scratches on the vehicle's
paint finish:
Rinse o ff 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.
CAUTION
 Do not use steel wool, abrasive
cleaners, or strong detergents
containing highly alkaline or caustic
agents on chrome-plated or
anodized aluminum parts. This may
damage the protective coating; also,
cleaners and detergents may discolor
or deteriorate the paint.

Connect the negative cable to a good ground point away from the battery:
Connecting the end of the second jumper cable to the negative (–) terminal of the
discharged battery is dangerous.
A spark could cause the gas around the battery to explode and injure someone.
Route the jumper cables away fr om parts that will be moving:
Connecting a jumper cable near or to moving parts (cooling fans, belts) is
dangerous. The cable could get caught when the engine starts and cause serious
injury.
CAUTION
Use only a 12 V booster system. You can dama ge a 12 V starter, ignition system, and
other electrical parts beyond repair with a 24 V power supply (two 12 V batteries in
series or a 24 V motor generator set).
1. Move the booster vehicle so that its battery is as close as possible to your
vehicle's battery.
2. Make sure that the power such as for th e headlights and air conditioner is turned
o ff.
3. Remove the battery cover.
4. Turn off the booster vehicle's engine and connect the jumper cables in the
following order.
Make sure that the jumper cables are se curely connected so that they do not
disconnect due to engine vibrations.

Overheating
▼Overheating
If the engine coolant temperature
gauge indicates overheating and the
high engine coolant temperature
warning indication is displayed, the
vehicle loses power or you hear a loud
knocking or pinging noise, the engine
is probably too hot.
WARNING
Pull over to a safe location, then
switch the ignition o ff 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.
Open the hood ONLY after steam is
no longer escaping from the engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you.
If the engine coolant temperature
gauge indicates overheating and the
high engine coolant temperature
warning indication is displayed:

1. Drive safely to the side of the road and park off the right-of-way.
2. Put a vehicle with an automatic transmission in park (P), a manual
transmission in neutral.
3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is escaping from the engine
compartment.

If steam is coming from the engine
compartment:
Do not go near the front of the
vehicle. Stop the engine.
Wait until the steam dissipates,
then open the hood and start the
engine.

If neither coolant nor steam is
escaping:
Open the hood and idle the engine
until it cools.
CAUTION
If the cooling fan does not operate
while the engine is running, the
engine temperature will increase.
Stop the engine and call an
Authorized Mazda Dealer.
