Putting the switch in the neutral
position sets the mirrors to auto-
matic mode. Automatic mode
allows the folding or unfolding of
the mirrors to be linked to lock-
ing/unlocking of the doors.
■Using automatic mode in cold
weather
When automatic mode is used in
cold weather, the door mirror could
freeze up and aut omatic stowing
and return may not be possible. In
this case, remove any ice and snow
from the door mirror, then either
operate the mirror using manual
mode or move the mirror by hand.
■Customization

Owners Manual_USA_M0C031_en
WARNING
■When taking a nap in the vehi-
cle
Always turn the hybrid system off.
Otherwise, if you accidentally
move the shift lever or depress
the accelerator pedal, this could
cause an accident or fire due to
hybrid system overheating. Addi-
tionally, if the vehicle is parked in
a poorly ventilated area, exhaust
gases may collect and enter the
vehicle, leading to death or a seri-
ous health hazard.
■When braking
●When the brakes a re wet, drive
more cautiously.
Braking distance increases
when the brakes are wet, and
this may cause one side of the
vehicle to brake differently than
the other side. Also, the parking
brake may not securely hold the
vehicle.
●If the electroni cally controlled
brake does not operate, do not
follow other vehicl es closely and
avoid hills or sharp turns that
require braking.
In this case, braking is still pos-
sible, but the brake pedal
should be depressed more
firmly than usual. Also, the brak-
ing distance will increase. Have
your brakes fixed immediately.
●The brake system consists of 2
or more individual hydraulic sys-
tems; if one of the systems fails,
the other will still operate. In this
case, the brake pedal should be
depressed more firmly than
usual and the braking distance
will increase. Have your brakes
fixed immediately.
■If the vehicle becomes stuck
Do not spin the wheels exces-
sively when a driven wheel is up
in the air, or the vehicle is stuck in
sand, mud, etc. This may damage
the driveline components or pro-
pel the vehicle forward or back-
ward, causing an accident.
NOTICE
■When driving the vehicle
●Do not depress the accelerator
and brake pedals at the same
time during driving, as this may
restrain the hybrid system out-
put.
●Do not use the accelerator
pedal or depress the accelera-
tor and brake pedals at the
same time to hold the vehicle on
a hill.
■When parking the vehicle
Always set the parking brake and
shift the shift lever to P. Failure to
do so may cause the vehicle to
move or the vehicle may acceler-
ate suddenly if t he accelerator
pedal is accidentally depressed.
■Avoiding damage to vehicle
parts
●Do not turn the steering wheel
fully in either direction and hold
it there for an extended period
of time.
Doing so may damage the
power steering motor.
●When driving over bumps in the
road, drive as slowly as possible
to avoid damaging the wheels,
underside of the vehicle, etc.

■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
■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.
●To restart the hybrid system
after performing an emergency
shutdown, shift the shift lever to

While driving on a road with
clear white (yellow) lane lines,
the LTA system warns the driver
if the vehicle may deviate from
the current lane
*, and also can
slightly operate the steering
wheel to help avoid deviation
from the lane. Also, while the
dynamic radar cruise control
with full-speed range is operat-
ing, this system will operate the
steering wheel to maintain the
vehicle’s lane position.
The LTA system recognizes
white (yellow) lane lines
* using
the front camera. Additionally, it
detects preceding vehicles
using the front camera and
radar.
*: May recognize the boundaries between the asphalt and the side
of the road, such as grass, soil, or
the curb, to be road lanes
LTA (Lane Tracing
Assist)
Summary of functions
WARNING
■Before using LTA system
●Do not rely solely upon the LTA
system. The LTA system does
not automatically drive the vehi-
cle or reduce the amount of
attention that m ust be paid to
the area in front of the vehicle.
The driver must always assume
full responsibilit y for driving
safely by paying careful atten-
tion to the surrounding condi-
tions and operating the steering
wheel to correct the path of the
vehicle. Also, the driver must
take adequate breaks when
fatigued, such as from driving
for a long period of time.
●Failure to perform appropriate
driving operations and pay care-
ful attention may lead to an
accident, resulting in death or
serious injury.
●The lane centering function will
be disabled automatically when
LTA detects a trailer connection.
Turn off the lane centering func-
tion if a trailer is connected and
it is not automatically disabled.
After trailer disconnect and
power switch is turned off, lance
centering function can be turned
on.
●Do not use the lane centering
system and steering assist func-
tion when the vehicle is lifted
unless using a Toyota official lift
up kit up to 4 in. (101 mm),
including tire height. Aftermar-
ket lift kits may degrade system
performance.
■Situations unsuitable for LTA
system
In the following situations, use the
LTA switch to turn the system off.
Failure to do so may lead to an
accident, resulting in death or
serious injury.
