Wiper Blades
▼Wiper Blades
CAUTION

Hot waxes applied by automatic car
washers have been known to affect the
wiper's ability to clean windows.
 To prevent damage to the wiper blades,
do not use gasoline, kerosene, paint
thinner, or other solvents on or near
them.
 When the wiper lever is in the AUTO
position and the ignition is switched ON,
the wipers may move automatically in
the following cases:
 If the windshield above the rain sensor
is touched.
 If the windshield above the rain sensor
is wiped with a cloth.
 If the windshield is struck with a hand
or other object.
 If the rain sensor is struck with a hand
or other object from inside the vehicle.
Be careful not to pinch hands or fingers
as it may cause injury, or damage the
wipers. When washing or servicing the
vehicle, make sure the wiper lever is in
the OFF position.
 Before lifting the windshield wiper blades
off the windshield, always follow the
procedure for moving the windshield
wiper blades. Otherw ise, a wiper blade,
wiper arm, or the hood could be
damaged.
Refer to the Replacin g Windshield Wiper
Blades (page on 6-22) section for the
procedure on how to move the
windshield wiper blades to the service
position.
Contamination of either the windshield or
the blades with foreign matter can reduce
wiper effectiveness. Common sources are
insects, tree sap, and hot wax treatments
used by some commercial car washes.

If the blades are not wiping properly, clean
the window and blades with a good
cleaner or mild detergent; then rinse
thoroughly with clean water. Repeat if
necessary.

Replace them.
CAUTION

To prevent damaging a windshield wiper
blade, wiper arm, or the hood, perform
the following procedure.
 Before lifting the windshield wiper
blades
off the windshield, always
move them to the service position.
 When putting the windshield wiper
blades back on the windshield, make
sure that they are in the service
position before switching the ignition
ON and operating the windshield
wipers.
 Replace with Mazda genuine wiper
blades. If they are replaced with wiper
blades other than a Mazda genuine
product, they may not wipe with the
same
efficiency as the genuine product.
 To prevent damage to the wiper arms
and other components, do not try to
sweep the wiper arm by hand.
 Do not bend the blade rubber
unnecessarily when replacing it.
Otherwise, the metal
stiffener in the
blade may deform and the windshield
wiper operation may be adversely affected.

when raising the wiper arm. Otherwise,
the part may deform and the wiping
performance may lower.

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 it s finish according to
the instructions in this section. These steps
should be taken immediately after you find
water marks on your vehicle's finish.
Paint Chipping
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 affected 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.

Jump-Starting
▼Jump-Starting
Jump-starting is dangerous if done incorrectly. S
o follow the procedure carefully. If you feel
unsure about jump-starting, we strongly recommend that you have a competent service
technician do the work.
WA R N I N G
Follow These Precautions Carefully:
To ensure safe and correct handling of the ba ttery, read the following precautions carefully
before using the battery or inspecting it.
Keep flames and sparks away from open battery cells and do not allow metal tools to
contact the positive (+) or negative (–) terminal of the battery when working near a battery.
Do not allow the positive (+) terminal to contact the vehicle body:
Flames and sparks near open battery cells are dangerous. Hydrogen gas, produced during
normal battery operation, could ignite and cause the battery to explode. An exploding battery
can cause serious burns and injuries. Keep all flames including cigarettes and sparks away
from open battery cells.
Keep all flames and sparks away from open battery cells because hydrogen gas is
produced from open battery cells while charging the battery or adding battery
fluid:
Flames and sparks near open battery cells are dangerous. Hydrogen gas, produced during
normal battery operation, could ignite and cause the battery to explode. An exploding battery

▼Towing Description
We recommend that towing be done only
by an Authorized Mazda Dealer or a
commercial tow-truck service.

Proper lifting and towing are necessary to
prevent damage to the vehicle. Particularly
when towing an AWD
vehicle, where all
the wheels are connected to the drive train,
proper transporting of the vehicle is
absolutely essential to avoid damaging the
drive system. Government and local laws
must be followed.
1. Wheel dollies

A towed FWD vehicle should have its
drive wheels (front wheels) off the ground.
If excessive damage or other conditions
prevent this, use wheel dollies.

When towing a FWD ve hicle with the rear
wheels on the ground, release the parking
brake.
Refer to Electric Par king Brake (EPB) on
page 4-64.

A towed AWD vehicle must have all its
wheels off the ground.
WA R N I N G
Always tow an AWD vehicle with all four
wheels off the ground:
Towing an AWD vehicle with either the
front or rear wheels on the ground is
dangerous as the drive train could be
damaged, or the vehicle could trail away
from the tow truck and cause an accident.
If the drive train has been damaged,
transport the vehicle on a flatbed truck.
CAUTION
 Do not tow the vehicle pointed backward
with driving wheels on the ground. This
may cause internal damage to the
transmission.
