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.

push and hold the “ENGINE START STOP” switch for more than 3 sec-
onds.

IGNITION ON mode for long periods without the engine running.
