slowly, and display changes may
be delayed.
For example, there is a lag
between the driver’s shifting and
the new shift r ange appearing on
the display. This lag could cause
the driver to downshift again,
causing rapid and excessive
engine braking and possibly an
accident resulting in death or
injury.
NOTICE
■To prevent damage to the
engine and its components
The engine may be overheating if
the engine coolant temperature
gauge is in the red zone (“H”). In
this case, immediately stop the
vehicle in a safe place, and check

Driving
vehicle control. This is espe-
cially true on wet or slippery
surfaces.
 Avoid jerky starts or sudden
acceleration.
 Avoid jerky steering and
sharp turns, and slow down
before making turn.
 Note that when making a turn,
the trailer wheels will be
closer than the vehicle wheels
to the inside of the turn. Com-
pensate by making a wider
than normal turning radius.
 Slow down before making a
turn, in cross winds, on wet or
slippery surfaces, etc.
Increasing vehicle speed can
destabilize the trailer.
Take care when passing other
vehicles. Passing requires
considerable distance. After
passing a vehicle, do not for-
get the length of your trailer,
and be sure you have plenty
of room before changing
lanes.
 To maintain engine braking
efficiency, when using engine
braking, do not use the trans-
mission in D.
 Instability happens more fre-
quently when descending
steep or long downhill grades.
Before descending, slow
down and downshift. Do not
make sudden downshifts
while descending steep or long downhill grades.
 Avoid holding the brake pedal
down too long or applying the
brakes too frequently. This
could cause the brakes to
overheat and result in
reduced braking efficiency.
 Due to the added load of the
trailer, your vehicle’s hybrid
system may overheat on hot
days (at temperatures over
85°F [30°C]) when driving up
a long or steep grade. If the
engine coolant temperature
gauge indicates overheating,
immediately turn off the air
conditioning (if in use), pull
your vehicle off the road and
stop in a safe spot. ( P.677)
 Always place wheel blocks
under both the vehicle’s and
the trailer’s wheels when
parking. Apply the parking
brake firmly, and put the
transmission in P. Avoid park-
ing on a slope, but if unavoid-
able, do so only after
performing the following:
1 Apply the brakes and keep
them applied.
2 Have someone place wheel
blocks under both the vehi-
cle’s and trailer’s wheels.
3 When the wheel blocks are in
place, release the brakes
slowly until the blocks absorb
the load.

2134-2. Driving procedures
4
Driving
from any power switch mode.
5Check that the “READY” indi-
cator is illuminated.
The vehicle will not move when the
“READY” indicator is off.
■If the hybrid system does not
start
●The immobilizer system may not
have been deactivated. ( P.81)
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 the 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 -22°F [-30°C])
under the influence of the outside
temperature, it may not be possi-
ble to start the h ybrid 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.
■Sounds and vibrations specific
to a hybrid vehicle
 P.74
■If the 12-volt b attery is dis-
charged
The hybrid system cannot be
started using the smart key system.
Refer to P.672to r estart the hybrid

■Steering lock function
●After turning the power switch to
OFF and opening and closing the
doors, the steeri ng wheel will be
locked due to the steering lock
function. Operating the power
switch again automatically can-
cels the steering lock.
●When the steering lock cannot be
released, “Push power switch
while turning the steering wheel in
either direction” will be displayed
on the multi-information display.
Check that the shift lever is set in
P. Press the power switch shortly
and firmly while turning the steer-
ing wheel left and right.
●To prevent the steering lock motor
from overheating , the motor may
be suspended if the hybrid system
is turned on and off repeatedly in
a short period of ti me. In this case,
refrain from operating the power
switch. After about 10 seconds,
the steering lo ck motor will
resume functioning.

2264-2. Driving procedures
on as described below:
ON: Comes on until the parking
brake is released.
Not in ON: Stays on for approxi-
mately 15 seconds.
●When the power switch is turned
off with the parking brake set, the
parking brake indicator light will
stay on for about 15 seconds. This
does not indicate a malfunction.
■When the parking brake switch
malfunctions
Automatic mode (automatic brake
setting and releas ing) will be turned
on automatically.
■Parking the vehicle
 P.189
■Parking brake engaged warning
buzzer
A buzzer will sound if the vehicle is
driven with the parking brake
engaged. “Parking Brake ON” is dis-
played on the multi-information dis-
play (with the v ehicle reaching a

WARNING
■When parking the vehicle
Do not leave a child in the vehicle
alone. The parking brake may be
released unintentionally by a child
and there is the danger of the
vehicle moving that may lead to
an accident resulting in death or
serious injury.
■Parking brake switch
Do not set any o bjects near the
parking brake switch. Objects
may interfere with the switch and
may lead the parking brake to
unexpectedly operate.
NOTICE
■When parking the vehicle
Before you leave the vehicle, shift
the shift lever to P, set the parking
brake and make s ure that the
vehicle does not move.
■When the system malfunc-
tions
Stop the vehicle in a safe place
and check the warning messages.
■When the parking brake can-
not be released due to a mal-
function
Driving the vehicle with the park-
ing brake set will lead to brake
components overheating, which
may affect braking performance
and increase brak e wear. Have
the vehicle insp ected by your
Toyota dealer immediately if this
occurs.

3724-5. Using the driving support systems
●When the power switch is turned
off.
●If only the TRAC system is turned
off, the TRAC will turn on when
vehicle speed increases.
If both the TRAC and VSC sys-
tems are turned off, automatic re-
enabling will not occur when vehi-
cle speed increases.
■Operating conditions of Active
Cornering Assist
The system operates when the fol-
lowing occurs.
●TRAC/VSC can operate
●The driver is at tempting to accel-
erate while turning
●The system detects that the vehi-
cle is drifting to the outer side

■Reduced effectiveness of the
EPS system
The effectiveness of the EPS sys-
tem is reduced to prevent the sys-
tem from overheating when there is
frequent steering input over an
extended period of time. The steer-
ing wheel may feel heavy as a result. Should this occur, refrain
from excessive steering input or
stop the vehicle a
nd turn the hybrid
system off. The EPS system should
return to normal within 10 minutes.
