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.

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.

WA R N I N G
Never tamper with the air bag/
pretensioner systems and always have an
Authorized Mazda Dealer perform all
servicing and repairs:
Self-servicing or tampering with the
systems is dangerous. An air bag/
pretensioner could accidentally activate or
become disabled causing serious injury or
death.
▼Tire Pressure Monitoring System
(TPMS) Warning Indication/
Warning Light (Flashing)
If there is a problem with the TPMS or the

Dealer.
WA R N I N G
Do not drive the vehicle at high speeds if
the TPMS warning light turns on or flashes:
Driving the vehicle at high speeds while the
TPMS warning light is turned on or flashing
is dangerous because the brake
performance and the steering wheel
operability will be reduced. If the vehicle is
driven at high speeds or the brakes are
suddenly applied, it could lead to an
accident. Gradually apply the brakes to
lower the vehicle's speed.
Do not ignore the TPMS warning light
when it is turned on or flashing:
Continuing to drive the vehicle while
ignoring the illumination/flashing of the
TPMS warning light is dangerous because a
tire may burst which could lead to an
accident. Take appropriate measures as
soon as possible.
