Turning the key from “ACC” to “LOCK”
Shift the shift lever to P. (P. 188)
Sounds and vibrations specific to a hybrid vehicle
P. 7 6
When the ambient temperature is low, such as during winter driving con-
ditions
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.
If the hybrid system does not start
The immobilizer system may not have been deactivated. (P. 82)
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional.
When the steering lock cannot be released
If the “READY” indicator does not come on
In the event that the “READY” indicator does not come on even after perform-
ing the proper procedures for starting the vehicle, contact any authorized Toy-
ota dealer or repairer, or another duly qualified and equipped professional
immediately.Push in the key and turn it to the
“LOCK” position.
When starting the hybrid system, the
power switch may seem stuck in the
“LOCK” position. To free it, turn the key
while turning the steering wheel slightly
left and right.

If the hybrid system does not start
The immobilizer system may not have been deactivated. (P. 82)
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional.
Steering lock
After turning the power switch off and opening and closing the doors, the
steering wheel will be locked due to the steering lock function. Operating the
power switch again automatically cancels the steering lock.
When the steering lock cannot be released
Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, the motor may be sus-
pended if the hybrid system is turned on and off repeatedly in a short period
of time. In this case, refrain from operating the hybrid system. After about 10
seconds, the steering lock motor will resume functioning.
If the “READY” indicator does not come on
If the event that the “READY” indicator does not come on even after perform-
ing the proper procedures for starting the vehicle, contact any authorized Toy-
ota dealer or repairer, or another duly qualified and equipped professional
immediately.
If the hybrid system is malfunctioning
P. 370 Check that the shift lever is securely set
in P. The hybrid system may not start if
the shift lever is displaced out of P. The
smart entry & start system indicator light
(green) will flash quickly.
The smart entry & start system indicator
light (green) will flash quickly.

Driving assist systems
ECB (Electronically Controlled Brake System)
The electronically controlled system generates braking force corre-
sponding to the brake operation
ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly,
or if the brakes are applied while driving on a slippery road surface
Brake assist
Generates an increased level of braking force after the brake pedal
is depressed when the system detects a panic stop situation
VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
TRC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
Hill-start assist control
Prevents the vehicle from rolling backward when starting on an
incline or slippery slope
EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel
To help enhance driving safety and performance, the following
systems operate automatically in response to various driving
situations. Be aware, however, that these systems are supple-
mentary and should not be relied upon too heavily when operat-
ing the vehicle.

2144-5. Using the driving support
Emergency brake signal
When the brakes are applied suddenly, the emergency flashers
automatically flash to alert the vehicle behind.
The slip indicator will flash while
the TRC/VSC/ABS systems are
operating.
If the vehicle gets stuck in mud, dirt or snow, the TRC system may
reduce power from the hybrid system to the wheels. Pressing the VSC
OFF switch to turn the system off may make it easier for you to rock
the vehicle in order to free it.
To turn the TRC system off,
quickly press and release the
VSC OFF switch.
The “TRC OFF” indicator will come
on.
Press the switch again to turn the
system back on.

Turning off both TRC and VSC systems
To turn the TRC and VSC systems off, press and hold the VSC OFF switch
for more than 3 seconds while the vehicle is stopped.
The “TRC OFF” indicator and the VSC OFF indicator will come on.
Press the switch again to turn the systems back on.
Sounds and vibrations caused by the ABS, brake assist, TRC, VSC and
hill-start assist control systems
Any of the following conditions may occur when the above systems are oper-
ating. None of these indicates that a malfunction has occurred.
Vibrations may be felt through the vehicle body and steering.
A motor sound may be heard after the vehicle comes to a stop.
The brake pedal may pulsate slightly after the ABS is activated.
The brake pedal may move down slightly after the ABS is activated.
ECB operating sound
ECB operating sound may be heard in the following cases, but it does not
indicate that a malfunction has occurred.
Operating sound heard from the engine compartment when the brake pedal
is operated.
Motor sound of the brake system heard from the front part of the vehicle
when the driver’s door is opened.
Operating sound heard from the engine compartment when one or two min-
utes passed after the stop of the hybrid system.
EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automatically
reactivated in the following situations:
When the power switch is turned off
If only the TRC system is turned off, the TRC will turn on when vehicle
speed increases
If both the TRC and VSC systems are turned off, automatic reactivation will
not occur when vehicle speed increases.

2164-5. Using the driving support
Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur, refrain
from excessive steering input or stop the vehicle and turn the hybrid system
off. The EPS system should return to normal within 10 minutes.
Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assist control will
operate:
The shift lever is in a position other than P or N (when starting off forward/
backward on an upward incline).
The vehicle is stopped.
The accelerator pedal is not depressed.
The parking brake is not engaged.
Automatic system cancelation of hill-start assist control
The hill-start assist control will turn off in any of the following situations:
The shift lever is moved to P or N.
The accelerator pedal is depressed.
The parking brake is engaged.
Approximately 2 seconds elapse after the brake pedal is released.
Operating conditions of emergency brake signal
When the following three conditions are met, the emergency brake signal will
operate:
The emergency flashers are off.
Actual vehicle speed is over 55 km/h (35 mph).
The brake pedal is depressed in a manner that cause the system to judge
from the vehicle deceleration that this is a sudden braking operation.
Automatic system cancelation of emergency brake signal
The emergency brake signal will turn off in any of the following situations:
The emergency flashers are turned on.
The brake pedal is released.
The system judges from the vehicle deceleration that is not a sudden brak-
ing operation.

WARNING
Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires
are installed on the vehicle.
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional for further information when replacing tires or
wheels.
Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.
