If the engine load increases and the
engine coolant temperature exceeds
100 °C (210 °F), the gauge indicates the
engine coolant temperature.
▼Fuel Gauge (Without
Multi-information Display)
The fuel gauge shows approximately how
much fuel is remaining in the tank when
the ignition is
switched ON. We
recommend keeping the tank over 1/4 full.

Full
1/4 Full
Empty
If the low fuel warnin g light illuminates or
the fuel level is very low, refuel as soon as
possible.
Refer to Taking Action on page 7-41.
NOTE
After refueling, it may require some time
for the indicator to stabilize. In addition,
the indicator may deviate while driving
on a slope or curve since the fuel moves
in the tank.
The display indicating a quarter or less
remaining fuel has more segments to
show the remaining fu el level in greater
detail.
The direction of the arrow () indicates
that the fuel-filler lid is on the left side
of the vehicle.
▼ Dashboard Illumination
(Without auto-light control)
When the position lights are turned on
with the ignition switched ON, the
brightness of the dash
board illumination is
dimmed.
(With auto-light control)
When the position lights are turned on
with the ignition switched ON, the
brightness of the dash board illumination is
dimmed. However, when the light sensor
detects that the surrounding area is bright
such as when the position lights are turned
on in the daytime, the dashboard
illumination does not dim.
NOTE
(With auto-light control)
When the ignition is switched ON in the
early evening or at dusk, the dashboard
illumination is dimmed for several
seconds until the light sensor detects the
brightness of the surrounding area,
however, the dimmer may cancel after
the brightness is detected.
When the position lights are turned on,
the position lights i ndicator light in the
instrument cluster turns on.
Refer to Headlights on page 4-44.
The brightness of the instrument cluster
and dashboard illuminations can be
adjusted by rotating the knob.

▼Wrench Indication/Indicator Light*
Type A instrument cluster
Perform maintenance in accordance with
the message.
Type B instrument cluster
When the ignition is switched ON, the
wrench indicator light is illuminated and
then turns off after a few seconds.
The wrench indicator light turns on when
the preset maintenance period arrives.
Verify the content and perform
maintenance.
Refer to Maintenance Monitor on page 6-
15.
▼ Low Engine Coolant Temperature
Indicator Light (Blue)
The light illuminates continuously when
the engine coolant temperature is low and
turns off after the engine is warm.
If the low engine c
oolant temperature
indicator light remains illuminated after
the engine has been sufficiently warmed
up, the temperature sensor could have a
malfunction. Consult an Authorized
Mazda Dealer.

CAUTION
Do not shade the light sensor by adhering a st icker or a label on the windshield. Otherwise
the light sensor will not operate correctly.
 The 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
position and the ignition
is switched ON as fingers could be pinched or the wipers and wiper blades could be
damaged when the wipers activate automaticall y. If you are going to clean the windshield,
be sure the wipers are turned off completely wh en it is particularly tempting to leave the
engine running. This is particularly important when clearing ice and snow.
NOTE
The 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 night time 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 lights turn off if the light switch is turned to the
position.
If the headlight switch and the windshield wiper switch are in , and the wipers are
operated at low or high speed by the auto wiper control for several seconds, bad weather
conditions are determined and the headlights may be turned on.
The sensitivity of the auto-light control may be changed.

When the wiper lever is in the
position, the rain sensor senses the amount
of rainfall on the windshield and turns the
wipers on or off automatically
(off―intermittent―low speed―high
speed).

The sensitivity of th
e rain sensor can be
adjusted by turning the switch on the
wiper lever.
From the center position (normal), rotate
the switch upward for higher sensitivity
(faster response) or r otate it downward for
less sensitivity (slower response).

When the wiper lever is in the
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 or wiped with a cloth.
 If the windshield is struck with a hand
or other object from either outside or
inside the vehicle.
Keep hands and scrapers clear of the
windshield when the wi per lever is in the
position and the ignition is
switched ON 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 (when it is most likely that the
engine is left running) this is particularly
important when clearing ice and snow.
NOTE
Switching the auto-wiper lever from the
to the position while driving
activates the windshield wipers once,
after which they operate according to
the rainfall amount.
The 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.
If the windshield is coated with water
repellent, the rain sensor may not be
able to sense the amount of rainfall
correctly and the auto-wiper control
may not operate properly.
If dirt or foreign matter (such as 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 wi pers cannot remove
this ice, dirt or foreign matter, the
auto-wiper control will stop operation.
In this case, set th e wiper lever to the
low speed position or high speed
position for manual operation, or
remove the ice, dirt or foreign matter by
hand to restore the auto-wiper
operation.
If the auto-wiper lever is left in the
position, the wipers could operate
automatically from the effect of strong
light sources, electromagnetic waves, or
infrared light because the rain sensor
uses an optical sensor. It is
recommended that the auto-wiper lever
be switched to the
position other
than when driving the vehicle under
rainy conditions.
If the headlight switch and the
windshield wiper switch are in
,
and the wipers are operated at low or
high speed by the auto wiper control for
several seconds, bad weather conditions
are determined and the headlights may
be turned on.
The auto-wiper control functions can be
turned off. Refer to Personalization
Features on page 9-9.

i-ACTIVSENSE*
i-ACTIVSENSE is a collective term covering a series of advanced safety and driver support
systems which make use of a Forw ard Sensing Camera (FSC) and radar sensors.
Because each system has its limitations, always drive carefully and do not rely solely on the
systems.

▼Camera and Sensors
Forward sensing camera (FSC)
The Forward Sensing Camera (FSC) determines the conditions ahea
d of the vehicle while
traveling at night and detects traffic lanes. The following systems also use the Forward
Sensing Camera (FSC).
High Beam Control system (HBC)
Lane Departure Warning System (LDWS)
The Forward Sensing Camera (FSC) is installed at the top of the windshield near the
rearview mirror.
Refer to Forward S ensing Camera (FSC) on page 4-94.
Radar sensors (rear)
The radar sensors (rear) function by detecting the radio waves reflected off a vehicle
approaching from the rear or an obstruction sent from the radar sensors. The following
systems also use the radar sensors (rear).
Blind Spot Monitoring (BSM)
Rear Cross Traffic Alert (RCTA)
The radar sensors (rear) are inst alled inside the rear bumper, one each on the left and right
sides.
Refer to Radar Sensors (Rear) on page 4-96.
