When stopping the engine with the shift lever in a position other
than PIf the engine is stopped with the sh ift lever in a position other than P,
the “ENGINE START STOP” switch will not be turned off but instead
be turned to ACCESSORY mode. Perform the following procedure to
turn the switch off:
Check that the parking brake is set.
Shift the shift lever to P.
Check that the indicator on the “ENGINE START STOP”
switch is illuminated in amber and then press the “ENGINE
START STOP” switch once.
Check that the indicator on the “ENGINE START STOP”
switch is off.
■Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes or

the shift lever in P, 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.
■ Operation of the “ENGINE START STOP” switch
When operating the “ENGINE START STOP” switch, one short, firm press is
enough. If the switch is pressed improperly, the engine may not start or the
“ENGINE START STOP” switch mode may not change. It is not necessary to
press and hold the switch.

pended if the engine is turned on and off repeatedly in a short period of time.
In this case, refrain from operating the engine. After about 10 seconds, the
steering lock motor will resume functioning.
The green indicator light on the “ENGINE

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 2 seconds,
or press it briefly 3 times or more in succession. ( P. 795)
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.
