4-2. Driving procedures
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 circumsta nces.
Doing so may cause an accident resulting in death or serious in jury.
■ Caution while driving
If the vehicle begins to slide due to engine failure or other c ircumstances, 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
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  th e  vehicle,
press and hold the engine switch for more than 2 seconds, or pr ess it briefly
3 times or more in succession. ( P. 463)
However,  do  not  touch  the  engine  switch  while  driving  except  in   an  emer-
gency. 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  o ver  and  stop
the vehicle as soon as it is safe to do so.
NOTICE
■ To prevent battery discharge
● Do  not  leave  the  engine  switch  in ACCESSORY  or  IGNITION  ON  mode
for long periods of time without the engine running.
● If the indicator on the engine switch is illuminated, the engin e switch is not
off. When exiting the vehicle, always check that the engine swi tch is off.
● Do not stop the engine when the shift lever is in a position ot her than P. If
the engine is stopped in another shift lever position, the engi ne switch will
not be turned off but instead be turned to ACCESSORY mode. If t he vehi-
cle is left in ACCESSORY mode, battery discharge may occur.
■ 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.
■ Symptoms indicating a malf unction with the engine switch
If the engine switch seems to be operating somewhat differently  than usual,
such as the switch sticking slightly, there may be a malfunctio n. 
Contact your Toyota dealer immediately.
