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
To drive using temporary shift range selection, operate the “-” pad-
dle shift switch. The shift range can then be selected by operating
the “-” and “+” paddle shift switches. Changing the shift range
allows restriction of the highest gear, 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 8, will be displayed in the
meter cluster.
To return to normal D position
driving, the “+” paddle shift
switch must be held down for a
period of time.
