821-3. Theft deterrent system
Immobilizer system
Vehicles without a smart entry & start system
The system begins operating after the key has been removed from
the power switch. The system is canceled after the registered key has
been inserted into the power switch.
Vehicles with a smart entry & start system
The system begins operating after the power switch has been turned
off. The system is canceled after the power switch has been turned to
ACCESSORY or ON mode.
System maintenance
The vehicle has a maintenance-free type immobilizer system.
Conditions that may cause the system to malfunction
If the grip portion of the key is in contact with a metallic object
If the key is in close proximity to or touching a key to the security system
(key with a built-in transponder chip) of another vehicle
The vehicle’s keys have built-in transponder chips that prevent
the hybrid system from starting if a key has not been previously
registered in the vehicle’s on-board computer.
Never leave the keys inside the vehicle when you leave the vehi-
cle.
This system is designed to help prevent vehicle theft but does
not guarantee absolute security against all vehicle thefts.

*1: These lights turn on when the power switch is turned to the “ON” position
(vehicles without a smart entry & start system) or ON mode (vehicles with
a smart entry & start system) to indicate that a system check is being per-
formed. They will turn off after the hybrid system on, or after a few sec-
onds. There may be a malfunction in a system if a light does not come on,
or if the lights do not turn off. Have the vehicle inspected by any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional.
*2: If equipped
*3: The light flashes to indicate that the system is operating.
*4: This light illuminates on the center panel.
WARNING
If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not
come on when you start the hybrid system, this could mean that these sys-
tems are not available to help protect you in an accident, which could result
in death or serious injury. Have the vehicle inspected by any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional immediately if this occurs.
NOTICE
To prevent damage to the engine and its components
The engine may be overheating if the high engine coolant temperature
warning light flashes or turns on. In this case, immediately stop the vehicle
in a safe place, and check the engine after it has cooled completely.

Driving
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.
Page 214 of 464
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.

Driving
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.

Driving
WARNING
The ABS does not operate effectively when
The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
The vehicle hydroplanes while driving at high speed on wet or slick roads.
Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the
following situations:
When driving on dirt, gravel or snow-covered roads
When driving with tire chains
When driving over bumps in the road
When driving over roads with potholes or roads with uneven surfaces
TRC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
Hill-start assist control does not operate effectively when
Do not overly rely on the hill-start assist control. The hill-start assist control
may not operate effectively on steep inclines and roads covered with ice.
Unlike the parking brake, hill-start assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.
When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRC/VSC systems off unless necessary.

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.
