■Auto power off function
Vehicles with an automatic transmission
If the vehicle is left in ACCESSORY or IGNITION ON mode (the engine is
not running) for more than an hour with the shift lever in P, the “ENGINE
START STOP” switch will automatically turn off. However, this function can-
not entirely prevent battery discharge. Do not leave the vehicle with the
“ENGINE START STOP” switch in ACCESSORY or IGNITION ON mode for
long periods of time when the engine is not running.
Vehicles with a manual transmission
If the vehicle is left in ACCESSORY or IGNITION ON mode (the engine is
not running) for more than an hour, the “ENGINE START STOP” switch will
automatically turn off. However, this function cannot entirely prevent battery
discharge. Do not leave the vehicle with the “ENGINE START STOP” switch
in ACCESSORY or IGNITION ON mode for long periods of time when the
engine is not running.

steering lock motor will resume functioning.

CAUTION
■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 circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Caution while driving
If the vehicle begins to slide due to engine failure or other circumstances, do
not lock or open the doors until the vehicle reaches a safe and complete
stop. Activation of the steering lock in this circumstance may lead to an acci-
dent, 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,
press and hold the “ENGINE START STOP” switch for more than 3 seconds,
or press it briefly 3 times or more in succession.
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.
