graduation marks in the fuel gauge
indicating the remaining fuel supply
disappear.
If there is no past fuel economy
information such as after first
purchasing your vehicle or the
information is deleted when the battery

NOTE
The Sport AT has an option that is not
included in the tr aditional 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 4-35).

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
4-35.
▼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 select ed 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.

Auto-light control
When the headlight switch is in the
position and the ignition is switched ON, the
light sensor senses the surrounding lightness or darkness and automatically turns the
headlights and other exterior lights on or off.
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 activa te automatically. If you are going to clean the windshield,
be sure the wipers are turned off completely when it is partic
ularly tempting to leave the
engine running. This is particularly important when clearing ice and snow.
NOTE
The headlights and other exterior lights 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 minute s such as inside long
tunnels, traffic jams inside tunn els, or in indoor parking lots.
