WARNING
■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.628)
However, do not touch the
engine switch while driving
except in an emergency. Turn-
ing the engine off while driving
will not cause loss of steering or
braking control, but the power
assist to thes e systems will be
lost. This will make it more diffi-
cult to steer and brake, so you
should pull over and stop the
vehicle as soon as it is safe to
do so.
●If the engine switch is operated
while the vehicle is running, a
warning message will be shown
on the multi-info rmation display
and a buzzer sounds.
●When restarting the engine after
an emergency shutdown, shift
t h e s h i f t l e v e r t o N a n d p r e s s t h e
engine switch shortly and firmly.
■When parking
Exhaust gases include harmful
carbon monoxide (CO), which is
colorless and odorless. Observe
the following precautions.
Failure to do so may cause
exhaust gases to enter the vehicle
and may lead to an accident
caused by light-headedness, or
may lead to death or a serious
health hazard.
●If the vehicle is in a poorly venti-
lated area or a closed area,
such as a garage, stop the
engine.
●Do not leave the vehicle with
the engine running for a long
time. If such a situation cannot
be avoided, park the vehicle in
an open space and ensure that
exhaust fumes do not enter the
vehicle interior.
●Do not leave the engine running
in an area with snow build-up,
or where it is snowing. If snow-
banks build up around the vehi-
cle while the engine is running,
exhaust gases may collect and
enter the vehicle.

●In the following situations, if the situation has changed (or the vehicle has
been driven for some time) and the normal operating conditions are
detected, the message will disappear and the system will become opera-
tional.
If the message does not disapp ear, contact your Toyota dealer.
• When the temperature around the radar sensor is outside of the opera-
tional range, such as when the vehicle is in the sun or in an e xtremely cold
environment
• When the front camera cannot d etect objects in front of the vehicle, such
as when driving in the dark, sno w, or fog, or when bright lights are shining
into the front camera
When the temperature around the
front camera is outside of the opera-
tional range, such as when the vehi-
cle is in the sun or in an extremely
cold environment
If the front camera is hot, such as
after the vehicle had been parked in
the sun, use the air conditioning sys-
tem to decrease the temperature
around the front camera.
If a sunshade was used when the
vehicle was parked, depending on its
type, the sunlight reflected from the
surface of the sunshade may cause
the temperature of the front camera
to become excessively high.
If the front camera is cold, such as
after the vehicle is parked in an
extremely cold environment, use the
air conditioning system to increase
the temperature around the front
camera.
The area in front o f the front camera
is obstructed, such as when the
hood is open or a sticker is attached
to the part of the win dshield in front
of the front camera.
Close the hood, rem ove the sticker,
etc. to clear the obstruction.
