Driving
4-2.Driving procedures
1 Pull the parking brake switch
to check that the parking
brake is set. ( P.205)
The parking brake indicator will
come on.
2Check that the shift lever is in
P.
3 Firmly depress the brake
pedal.
and a message will be dis-
played on the multi-information dis-
play.
If it is not displayed, the hybrid sys-
tem cannot be started.
4 Press the power switch
shortly and firmly.
When operating the power switch,
one short, firm press is enough. It is
not necessary to press and hold the
switch.
If the “READY” indicator turns on,
the hybrid system will operate nor-
mally.
Continue depressing the brake
pedal until the “READY” indicator is
illuminated.
The hybrid system can be started from any power switch mode.
5
Check that the “READY” indi-
cator is illuminated.
The vehicle cannot be driven if the
“READY” indicator is off.
■If the hybrid system does not
start
●The immobilizer system may not
have been deactivated. ( P. 8 1 )
Contact your Toyota dealer.
●If a message related to start-up is
shown on the multi-information
display, read the message and fol-
low the instructions.
■When the ambient temperature
is low, such as during winter
driving conditions
●When starting th e hybrid system,
the flashing time of the “READY”
indicator may be long. Leave the
vehicle as it is until the “READY”
indicator is steady on, as steady
means the vehicle is able to move.
●When the hybrid battery (traction
battery) is extremely cold (below
approximately -31°F [-35°C])
under the influenc e of the outside
temperature, it ma y not be possi-
ble to start the hybrid system. In
this case, try to start the hybrid
system again after the tempera-
ture of the hybrid battery
increases due to the outside tem-
perature increase, etc.
●When the outside temperature is
extremely cold, the hybrid system
may be started by starter motor.
Power (ignition)
switch
Performing the following
operations when carrying
the electronic key on your
person starts the hybrid
system or changes power
switch modes.

Driving
1 Stop the vehicle completely.
2 Set the parking brake
( P.205), and shift the shift
lever to P.
Check the parking brake indicator
is illuminated.
3 Press the power switch
shortly and firmly.
The hybrid system will stop, and the
meter display will be extinguished.
4Release the brake pedal and
check that “ACCESSORY” or
“IGNITION ON” is not shown
on the meter.
■Automatic hybrid system shut
off feature
●The vehicle is equipped with a
feature that automatically shuts off
the hybrid system when the shift
lever is in P with the hybrid system
operating for an extended period.
●The hybrid system will automati- cally shut off after approximately 1
hour if it has been left running
while the shift lever is in P.
●The timer for the automatic hybrid
system shut off feature will reset if
the brake pedal is depressed or if
the shift lever is in a position other
than P.
●After the vehicle
is parked, if the
door is locked with the door lock
switch ( P.116) from the inside or
the mechanical key ( P.112) from
the outside, the automatic hybrid
system shut off feature will be dis-
abled. The timer for the automatic
hybrid syste m shut off feature will
be re-enabled if the driver’s door
is opened.
NOTICE
■When starting the hybrid sys-
tem
If the hybrid system becomes diffi-
cult to start, have your vehicle
checked by your Toyota dealer
immediately.
■Symptoms indicating a mal-
function with the power
switch
If the power switch seems to be
operating somewh at differently
than usual, such as the switch
sticking slightly, there may be a
malfunction. Contact your Toyota
dealer immediately.
Stopping the hybrid sys-
temWARNING
■Stopping the hybrid system
in an emergency
●If you want to stop the hybrid
system in an emergency while
driving the vehicle, press and
hold the power s witch for more
than 2 seconds, or press it
briefly 3 times or more in suc-
cession. ( P.494)
However, do not touch the
power switch while driving
except in an emergency. Turn-
ing the hybrid s ystem off while
driving will not cause loss of
steering or braking control, but
the power assist to these sys-
tems 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.
●If the power switch is operated
while the vehicle is running, a
warning message will be shown
on the multi-information display
and a buzzer sounds.

shutdown, shift the shift lever to
N and then press the power
switch.
■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
hybrid system.
●Do not leave the vehicle with
the hybrid system operating 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 hybrid system
operating in an area with snow
build-up, or where it is snowing.
If snowbanks build up around
the vehicle while the hybrid sys-
tem is operating, exhaust gases
may collect and enter the vehi-
cle.

engine wear due to dirt in the air.

5448-1. Specifications
Owners Manual_USA_M0C052_en
Oil viscosity (0W-20 is explained
here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil
which allows cold startability.
Oils with a lower value before
the W allow for easier starting
of the engine in cold weather.
• The 20 in 0W-20 indicates the viscosity characteristic of the
oil when the oil is at high tem-
perature.
How to read oil container label:
The International Lubricant Specification Advisory Commit-
tee (ILSAC) Certification Mark is
added to some oil containers to
help you select the oil you
should use.
*: The fluid capacity is a reference quantity.
If replacement is necessary, contact your Toyota dealer.
