CAUTION
When starting the engine
Always start the engine while sitting in the driver's seat. Do not press the
accelerator while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle,
push and hold the “ENGINE START STOP” switch for more than 3 sec-
onds.
However, do not touch the “ENGINE START STOP” switch while driving
except in an emergency. Turning the engine off while driving will not cause
loss of steering or braking control, but the power assist to these systems will
be lost. This will make it more difficult to steer and brake, so you should
pull over and stop the vehicle as soon as it is safe to do so.
NOTICE
To prevent battery discharge
Do not leave the “ENGINE START STOP” switch in ACCESSORY or
IGNITION ON mode for long periods without the engine running.
When starting the engine
Do not race a cold engine.
If the engine becomes difficult to start or stalls frequently, have the engine
checked immediately.

Selecting shift ranges in the D position (if equipped)
To drive using temporary shift range selection, operate the “-” shift
paddle switch. The shift range can then be selected by operating
the “-” and “+” shift paddle switches. Changing the shift range
allows restriction of the upper limit of the gears to be used, pre-
venting unnecessary upshifting and enabling the level of engine
braking force to be selected.
Higher shift range
Lower shift range
The selected shift range, from 1
to 6, will be displayed in the
meter cluster.
To return to normal D position
driving, the “+” shift paddle
switch must be held down for a
period of time.

Changing shift ranges in S mode
To enter S mode, shift the shift lever to the S position. The shift
range can then be selected by operating the “-” and “+” shift pad-
dle switches (if equipped) or the shift lever. Changing the shift
range allows restriction of the upper limit of the gears to be used,
preventing unnecessary upshifting and enabling the level of engine
braking force to be selected.
Higher shift range
Lower shift range
The selected shift range, from 1
to 6, will be displayed in the
meter cluster.
The initial shift range in S mode is automatically set to 5 or 4
according to vehicle speed. However, the initial shift range may be
set to 3 or 2 if the AI-SHIFT has operated while the shift lever was
in the D position.
