▼Tachometer
The tachometer shows engine speed in
thousands of revolutions per minute
(rpm).
CAUTION
Do not run the engine with the
tachometer needle in the RED ZONE.
This may cause severe engine damage.

1. STRIPED ZONE*1
2. RED ZONE*1
*1 The range varies depending on the type of
gauge.
NOTE
When the tachometer needle enters
the STRIPED ZONE, this indicates to
the driver that the gears should be
shifted before entering the RED ZONE.

▼Engine Coolant Temperature
Gauge
Displays the engine coolant
temperature. The blue range of the
gauge indicates that the engine coolant
temperature is low, and the red range
of the gauge indicates that the engine
coolant temperature is high and
overheating.

CAUTION
When the engine coolant temperature
gauge needle is in the red range, the
engine coolant temperature is
extremely high. Drive slowly to reduce
engine load. If the engine coolant
temperature gauge needle is in the red
range, there is the possibility of
overheating. Park the vehicle in a safe
place immediately and take
appropriate measures.
Refer to Overheating on page 7-21.
NOTE
If the engine or engine coolant
temperature is high or low, the
engine output may be restricted to
protect the engine.
▼Fuel Gauge
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.

1. Full
2. 1/4 Full
3. Empty

If the low fuel warning light illuminates
or the fuel level is very low, refuel as
soon as possible.
If inconsistency in engine performance
or stalling occurs due to low fuel level
conditions, refuel the vehicle as soon
as possible and add at least 10 L (2.7
US gal, 2.2 Imp gal) of fuel.
Refer to Low Fuel Warning Indication/
Warning Light on page 7-35.
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 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 lights are turned on with the
ignition switched ON, the brightness of
the dashboard illumination is dimmed.
(With auto-light control)
When the lights are turned on with the
ignition switched ON, the brightness of
the dashboard illumination is dimmed.
However, when the light sensor
detects that the surrounding area is
bright such as when the 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
dimming may cancel after the
brightness is detected.
When the lights are turned on, the
lights-on indicator light in the
instrument cluster turns on.
Refer to Headlights on page 4-57.
The brightness of the instrument panel
and dashboard illuminations can be
adjusted by pressing the dashboard
illumination switch while the
dashboard illumination is dimmed.
The brightness increases by pressing
the + switch.
The brightness decreases by pressing
the - switch. If you press the - switch
while the instrument cluster is at
maximum dimness, a sound is
activated to notify you that the
current dimmer setting is at
maximum dimness.

▼Wrench Indication/Indicator Light
The wrench indication/indicator light
is displayed/turns on under the
following conditions.
When the preset maintenance
period has arrived.
Refer to the Information section in
the Mazda Connect Owner's
Manual.
CAUTION

When the maintenance period
arrives, have your vehicle inspected
by an Authorized Mazda Dealer as
soon as possible. If maintenance is
neglected, a decrease in vehicle
performance may occur which
could cause damage. Have your
vehicle inspected before the
maintenance period arrives.
 If the vehicle continues to be
driven after the engine oil
replacement period has passed, it
could cause damage to the engine.
Replace the engine oil before the
maintenance period arrives.
NOTE
The wrench indication/indicator
light may display/turn on earlier than
the preset period depending on
vehicle usage conditions.
Whenever the engine oil is replaced,
a reset of the vehicle engine control
unit is necessary.
Refer to the Information section in
the Mazda Connect Owner's
Manual.

Manual TransmissionShift Pattern
▼Manual Transmission Shift Pattern
1. Neutral position

The shift pattern of the transmission is
conventional, as shown.

Depress the clutch pedal all the way
down while shifting; then release it
slowly.

Your vehicle is equipped with a device
to prevent shifting to R (reverse) by
mistake. Push the shift lever downward
and shift to R.

WARNING
Do not use sudden engine braking on
slippery road surfaces or at high
speeds:
Shifting down while driving on wet,
snowy, or frozen roads, or while
driving at high speeds causes sudden
engine braking , which is dangerous.
The sudden change in tire speed could
cause the tires to skid. This could lead
to loss of vehicle control and an
accident.
Always leave the shift lever in 1 or R
position and set the parking brake
when leaving the vehicle unattended:
Otherwise the vehicle could move and
cause an accident.
CAUTION
 Keep your foot off the clutch pedal
except when shifting gears. Also, do
not use the clutch to hold the vehicle
on an upgrade. Riding the clutch will
cause needless clutch wear and
damage.
 Do not apply any excessive lateral
force to the shift lever when
changing from 5th to 4th gear. This
could lead to the accidental
selection of 2nd gear, which could
result in damage to the transmission.
 Make sure the vehicle comes to a
complete stop before shifting to R.
Shifting to R while the vehicle is still
moving may damage the
transmission.
NOTE
If shifting to R is
difficult, shift back
into neutral, release the clutch pedal,
and try again.
(With parking sensor system)

When the shift lever is shifted to the
R position with the ignition switched
ON, the parking sensor system is
activated and a beep sound is heard.
Refer to Parking Sensor System on
page 4-247.
▼Gear Shift Indicator (GSI)
The GSI supports you to obtain
optimum fuel economy and smooth
driving. It displays the selected gear
position in the instrument cluster as
well as notifies the driver to change to
the most suitable gear position
corresponding to the actual driving
condition.

1. Selected gear position
2. Suitable gear position
Indication
Condition
Numeral The selected gear position is
displayed.
and numer-
al Shift up or down to the indi-
cated gear position is recom-
mended.
CAUTION
Do not rely solely on the shift-up/
shift-down recommendations by
indications. The actual driving situation
might require shift operations
different
from indication. To avoid the risk of
accidents, the road and traffic
conditions have to be judged correctly
by the driver before shifting.
NOTE
The GSI turns off when the following
operations are performed.
The vehicle is stopped.The vehicle is put in neutral.The vehicle is driven in reverse.The clutch is not fully engaged when
accelerating from a stop.
The clutch pedal remains depressed
for 2 seconds or longer while driving.
▼ Recommendations for Shifting
Upshifting
For normal acceleration, Mazda
recommends these shift points:
(U.S.A. and Canada)
Gear
Vehicle speed
1 to 2 24 km/h (15 mph)
2 to 3 42 km/h (26 mph)
3 to 4 60 km/h (37 mph)
4 to 5 75 km/h (46 mph)
5 to 6 79 km/h (49 mph)
For cruising, Mazda recommends these
shift points:
(U.S.A. and Canada)
Gear Vehicle speed
1 to 2 13 km/h (8 mph)
2 to 3 29 km/h (18 mph)
3 to 4 49 km/h (30 mph)
4 to 5 63 km/h (39 mph)
5 to 6 70 km/h (43 mph)
Downshifting
When you must slow down in heavy
traffic or on a steep upgrade ,
downshift before the engine starts to
overwork. This reduces the chance of
stalling and gives better acceleration
when you need more speed.
