WARNING
■
When starting the engine
●Always  start  the  engine  while  sitting  in  the  driver’s  seat.  Do  not  depress
the accelerator pedal while starting the engine under any circu mstances. 
Doing so may cause an accident resulting in death or serious in jury.
● If the smart key system indicator light flashes in green after  the engine has
started,  never  drive  the  vehicle.  The  steering  wheel  is  still  l ocked,  and  it
may result in an accident. 
■ Caution while driving
If  engine  failure  occurs  while  the  vehicle  is  moving,  do  not  lo ck  or  open  the
doors  until  the  vehicle  reaches  a  safe  and  complete  stop. Activ ation  of  the
steering lock in this circumstance may lead to an accident, res ulting in death
or serious injury.

If  you  want  to  stop  the  engine  in  an  emergency  while  driving  th e  vehicle,
press and hold the “ENGINE START STOP” switch for more than 2 s econds,
or press it briefly 3 times or more in succession. ( P. 455)

except  in  an  emergency. Turning  the  engine  off  while  driving  wi ll  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, s o you should pull
over and stop the vehicle as soon as it is safe to do so.
