■ 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.

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.

WARNING
■Cautions regarding the assist functions of the system
By means of warnings and brake control, the pre-crash safety system is
intended to assist the driver in avoiding collisions through the process of
LOOK-JUDGE-ACT. There are limits to the degree of assistance the system
can provide, so keep in mind the following important points.
● Assisting the driver in watching the road
The pre-crash safety system is only able to detect vehicles directly in front
of your vehicle, and only within a limi ted range. It does not allow for care-
less or inattentive driving, and is not a system that can assist the driver in
low-visibility conditions. It is still necessary for the driver to pay close atten-
tion to the vehicle’s surroundings.
● Assisting the driver in making correct judgement
When attempting to estimate the possibility of a collision, the only data
available to the pre-crash safety system is that from vehicles it has
detected directly in front of the vehicle. Therefore, it is absolutely neces-
sary for the driver to remain vigila nt and to determine whether or not there
is a possibility of collision in any given situation.
● Assisting the driver in taking action
The pre-crash brake assist and pre- crash braking functions are designed
to help avoid a collision or reduce the severity of a collision, as such they
only operate when the system has determined that the possibility of a col-
lision is high. This system is not capable of automatically avoiding a colli-
sion or bringing the vehicle to a stop safely, without appropriate operations
being performed by the driver. For this reason, when encountering a dan-
gerous situation the driver must take direct and immediate action in order
to ensure the safety of all involved.
NOTICE
■ To avoid malfunction of the system
In the following situations, disable the pre-crash safety system. The system
may operate even if there is no possibility of a collision.
● When inspecting the vehicle using a drum tester such as a chassis dyna-
mometer or speedometer tester, or when using an on vehicle wheel bal-
ancer
● When transporting the vehicle via boat, truck, or similar means of transpor-
tation
● When the front part of the vehicle is raised or lowered, such as if tires of a
different size than specified are used or if the suspension components are
modified
● When the vehicle is being towed

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.

◆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.
On vehicles with pre-crash safety system, pre-crash brake assist and pre-
crash braking will also be disabled. The PCS warning light will come 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.

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 t he 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 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.
