▼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.
During normal driving, the engine
coolant temperature stabilizes at 100 °C
(210 °F) or less, and the gauge indicates
a range lower than 100 °C (210 °F).
▼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 7-34.
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
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
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 4-44.
The brightness of the instrument panel and
dashboard illuminations can be adjusted
by pressing the dashboard illumination
switch while the dashbo ard 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.

visibility is reduced due to glare from
surrounding brightness, cancel the
illumination dimmer.

canceled, the instrument cluster cannot
be dimmed even if the lights are turned
on.
When the illumina tion dimmer is
canceled, the screen in the center
display switches to constant display of
the daytime screen.
▼ Outside Tempera
ture Display

from the actual outside temperature
depending on the surroundings and
vehicle conditions:
Significantly cold or hot temperatures.
Sudden changes in outside
temperature.
The vehicle is parked.

Automatic TransmissionControls
▼Automatic Transmission Controls
1. Lock-release button
2. Selector lever

Indication Various Lockouts
Indicates that you must depress the
brake pedal and hold in the lock-re‐
lease button to shift (The ignition
must be switched ON).
Indicates the selector lever can be
shifted freely into any position.
Indicates that you must hold in the
lock-release button to shift.
NOTE
The Sport AT has an option that is not
included in the traditional automatic
transmission that gives the driver the
option of selecting each gear instead of
leaving it to the transmission to shift
gears. Even if you intend to use the
automatic transmission functions as a
traditional automatic, you should also be
aware that you can inadvertently shift into
manual shift mode and an inappropriate
gear may be retained as the vehicle speed
increases. If you notice the engine speed
going higher or hear the engine racing,
confirm you have not accidentally slipped
into manual shift mode (page 4-36).

M (Manual)
M is the manual shift mode position.
Gears can be shifted up or down by
operating the selector lever.
Refer to Manual Shift Mode on page
4-36.
▼Shift Position Indication
1. Shift position indication

The selector position is indicated when the
ignition is switched ON.
Gear position indication
In manual shift mode, the “M” of the shift
position indication illuminates and the
numeral for the selected gear is displayed.
▼ Active Adaptive Shift (AAS)
Active Adaptive Shift (AAS)
automatically controls the transmission
shift points to best suit the road conditions
and driver input. This improves driving
feel. The transmission may switch to AAS
mode when driving up and down slopes,
cornering, driving at
high elevations, or
depressing the accelerator pedal quickly
while the selector lever is in the D
position. Depending on the road and
driving conditions/vehicle operations, gear
shifting could be delayed or not occur,
however, this does not indicate a problem
because the AAS mode will maintain the
optimum gear position.
Manual Shift Mode
▼ Manual Shift Mode
The manual shift mode gives you the feel
of driving a manual transmission vehicle
by allowing you to operate the selector
lever manually. This allows you to control
engine rpm and torque to the drive wheels
much like a manual transmission when
more control is desired.
To change to manual shift mode, shift the
lever from D to M.

NOTE
Changing to manual shift mode while
driving will not damage the
transmission.
If you change to manual shift mode
when the vehicle is stopped, the gear
will shift to M1.
If you change to manual shift mode
without depressing the accelerator pedal
when driving in D range, 5th gear/6th
gear, the gear will shift to M4/M5.
To return to automatic shift mode, shift the
lever from M to D.
