Even if the light turns off have your brake
system inspected as soon as possible by
an Authorized Mazda Dealer.
NOTE
Having to add brake fluid is sometimes an
indicator of leakage. Consult an Authorized
Mazda Dealer as soon as possible even if the
brake light is no longer illuminated.
WARNING
Do not drive with the brake system
warning light illuminated. Contact an
Authorized Mazda Dealer to have the
brakes inspected as soon as possible:
Driving with the brake system
warning light illuminated is
dangerous. It indicates that your

they could completely fail at any
time. If this light remains
illuminated, after checking that the
parking brake is fully released, have
the brakes inspected immediately.
qABS Warning Light
The warning light stays on for a few
seconds when the ignition switch is turned
to the ON position.If the ABS warning light stays on while

as if the vehicle had no ABS.
Should this happen, consult an Authorized
Mazda Dealer as soon as possible.
NOTE
lWhen the engine is jump-started to charge
the battery, uneven rpm occurs and the ABS
warning light may illuminate. If this occurs,
it is the result of the weak battery and does
not indicate an ABS malfunction.
Recharge the battery.
lThe brake assist system does not operate
while the ABS warning light is illuminated.
qElectronic Brake Force
Distribution System Warning
If the electronic brake force distribution
control unit determines that some
components are operating incorrectly, the

warning light on simultaneously. The
problem is likely to be the electronic
brake force distribution system.

Lighting Control
qHeadlights
CAUTION
(With AUTO position)
ØDo not shade the light sensor by
adhering a sticker or a label on
the windshield. Otherwise the light
sensor will not operate correctly.
Light sensor
ØThe light sensor also works as a
rain sensor for the auto-wiper
control. Keep hands and scrapers
clear of the windshield when the
wiper lever is in the AUTO position
and the ignition switch is in the
ON position as fingers could be
pinched or the wipers and wiper
blades damaged when the wipers
activate automatically. If you are
going to clean the windshield, be
sure the wipers are turned off
completely - this is particularly
important when clearing ice and
snow - when it is particularly
tempting to leave the engine
running.NOTE
lIf the light switch is left on, the lights will
automatically switch off approximately 30
seconds after turning the ignition switch to
the ACC or LOCK position.
lTo prevent discharging the battery, do not
leave the lights on while the engine is off
unless safety requires them.
(With AUTO position)lThe headlights, other exterior lights
and dashboard illumination may not
turn off immediately even if the
surrounding area becomes well-lit
because the light sensor determines that
it is nighttime if the surrounding area is
continuously dark for several minutes
such as inside long tunnels, traffic jams
inside tunnels, or in indoor parking
lots.
In this case, the light turns off if the
light switch is turned to the OFF
position.
lThe timing for turning on the
headlights, other exterior lights and
dashboard illumination can be delayed
by adjusting the sensitivity of the light
sensor. Consult an Authorized Mazda
Dealer regarding sensor adjustment.
lThe sensitivity of the AUTO lights
may be changed by an Authorized
Mazda Dealer.
lInstrument panel illumination can be
adjusted by rotating the knob in the
instrument cluster. Also, day/night
mode can be changed by pressing the
knob.
To adjust the brightness of the
dashboard illumination:
Refer to Dashboard Illumination on
page 5-41.

ØWhen the wiper lever is in the
AUTO position and the ignition
switch is in the ON position, the
wipers may move automatically in
the following cases:
ØIf the windshield above the rain
sensor is touched.
ØIf the windshield above the rain
sensor is wiped with a cloth.
ØIf the windshield is struck with
a hand or other object.
ØIf the rain sensor is struck with
a hand or other object from
inside the vehicle.
Keep hands and scrapers clear of
the windshield when the wiper
lever is in the AUTO position and
the ignition switch is in the ON
position as fingers could be
pinched or the wipers and wiper
blades damaged when the wipers
activate automatically.
If you are going to clean the
windshield, be sure the wipers are
turned off completely - this is
particularly important when
clearing ice and snow - when it is
particularly tempting to leave the
engine running.NOTE
lSwitching the auto-wiper lever from the
OFF to the AUTO position while driving at
a vehicle speed of 4 km/h (2 mph) or higher
(or after driving the vehicle) activates the
windshield wipers once, after which they
operate according to the rainfall amount.
lThe auto-wiper control may not operate
when the rain sensor temperature is about
_
10 °C (14 °F) or lower, or about 85 °C
(185 °F) or higher.
lIf the windshield is coated with water
repellent, the rain sensor may not be able to
sense the amount of rainfall correctly and
auto-wiper control may not operate
properly.
lIf dirt or foreign matter (e.g. ice or matter
containing salt water) adheres to the
windshield above the rain sensor or if the
windshield is iced, it could cause the wipers
to move automatically. However, if the
wipers cannot remove this ice, dirt or
foreign matter, the auto-wiper control will
stop operation. In this case, pull the wiper
lever to the low speed or high speed
position for manual operation, or remove
the ice, dirt or foreign matter by hand to
restore the auto-wiper operation.
