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 circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Caution while driving
Do not turn the engine switch to the “LOCK” position while driving. If, in an
emergency, you must turn the engine off while the vehicle is moving, turn
the engine switch only to the “ACC” position to stop the engine. An accident
may result if the engine is stopped while driving. ( →P. 505)
NOTICE
■To prevent battery discharge
Do not leave the engine switch in the “ACC” or “ON” position for long peri-
ods of time without the engine running.
■ When starting the engine
● Do not crank the engine for more than 30 seconds at a time. This may
overheat the starter and wiring system.
● Do not race a cold engine.
● If the engine becomes difficult to start or stalls frequently, have your vehi-
cle checked by your Toyota dealer immediately.

1944-2. Driving procedures
If the engine is stopped with the shift lever in a position other than P,
the engine switch will not be turned off but instead be turned to
ACCESSORY mode. Perform the following procedure to turn the
switch off:

1964-2. 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 circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Caution while driving
If engine failure occurs while the vehicle is moving, do not lock or open the
doors until the vehicle reaches a safe and complete stop. Otherwise, the
steering lock function will activate and this may lead to an accident, result-
ing 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 switch for more than 2 seconds, or press it briefly
3 times or more in succession. ( →P. 505)
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, however, power assist to the steering will be lost. This will
make it more difficult to steer smoothly, so you should pull over 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 “ACCESSORY” or “IGNITION ON” is displayed on the multi-information
display while the engine is not running, the engine switch is not off. Exit the
vehicle after turning the engine switch off.
● Do not stop the engine when the shift lever is in a position other than P. If
the engine is stopped in another shift lever position, the engine switch will
not be turned off but instead be turned to ACCESSORY mode. If the 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 your vehi-
cle checked by your Toyota dealer immediately.
■ Symptoms indicating a malfunction 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 malfunction. Contact
your Toyota dealer immediately.

turn on automatically if vehicle speed increases.
■ If the brake system overheats
The system will cease operation and a buzzer will sound to alert the driver.
Stop the vehicle in a safe place. (There is no problem with continuing normal
driving.) The system will be automatically restored after a short time.
WARNING
■To avoid an accident
● Do not use the AUTO LSD system in conditions other than the above.
A much greater steering effort and more careful cornering control will be
required.
