The engine may be overheating if the high coolant temperature warning light
comes on or flashes. In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. (→P. 6 0 3 )
Do not place anything or attach a sticker
in front of the instrument cluster. The item
may obscure or obstruct the display, or
could reflect off the display, possibly
causing an accident.

When driving
CAUTION
■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS airbag warning light
not come on when you start the hybrid system, this could mean that these
systems are not available to help protect you in an accident, which could
result in death or serious injury. Have the vehicle inspected by your Toyota
dealer immediately if this occurs.
■Warning lights
Warning lights inform the driver of malfunctions in any of the
vehicle’s systems. (→P. 5 3 5 )
*1:These lights turn on when the “POWER” switch is turned to ON
mode to indicate that a system check is being performed. They will
turn off after the hybrid system is on, or after a few seconds. 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 your Toyota
dealer.

■Warning lights, messages and buzzers for dynamic radar cruise con-
trol
Warning lights, warning messages and buzzers are used to indicate a sys-
tem malfunction or to inform the driver of the need for caution while driving.
■Certification
For vehicles sold in the U.S.A.
FCC ID: HYQDNMWR004
This device complies with part 15 of the FCC Rules. Operation is subject to
the following two conditions: (1) This device may not cause harmful interfer-
ence, and (2) this device must accept any interference received, including
interference that may cause undesired operation.
FCC WARNING
Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.

■Sounds and vibrations caused by the ABS, brake assist, VSC and
TRAC
●A sound may be heard from the engine compartment when the hybrid
system is started, just after the vehicle begins to move, if the brake pedal
is depressed forcefully or repeatedly, or 1-2 minutes after the hybrid sys-
tem is stopped. This sound does not indicate that a malfunction has
occurred in any of these systems.
●Any of the following conditions may occur when the above systems are
operating. 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.
■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may
be heard. This does not indicate a malfunction.
■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.

PCS (Pre-Collision System)∗
∗: If equipped
When the radar sensor detects possibility of a frontal collision, the
pre-collision systems such as the brakes and seat belts are automat-
ically engaged to lessen impact as well as vehicle damage.
■Pre-collision seat belts (front seat belts only)
If the pre-collision sensor detects that a collision is unavoidable, the
pre-collision system will retract the seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or
loses control of the vehicle. (→P. 1 6 2 )
However, when the VSC system is disabled, the system will not oper-
ate in the event of skidding.
■Pre-collision brake assist
When there is a high possibility of a frontal collision, the system applies
greater braking force in relation to how strongly the brake pedal is
depressed.
■Pre-collision braking
When there is a high possibility of a frontal collision, the system warns
the driver using a warning light, warning display and buzzer. If the sys-
tem determines that a collision is unavoidable, the brakes are automat-
ically applied to reduce the collision speed. Pre-collision braking can be
disabled using the pre-collision braking off switch.

Disabling pre-collision braking
Pre-collision braking enabled
Pre-collision braking disabled
The “PCS” warning light will
turn on when pre-collision
braking is disabled.
Radar sensor
The radar sensor detects vehi-
cles or other obstacles on or
near the road ahead and deter-
mines whether a collision is
imminent based on the position,
speed, and heading of the obsta-
cles.

When driving
■Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may
also be occasions when the sensor cannot detect pedestrians, animals,
bicycles, motorcycles, trees, or snowdrifts.
■Situations in which the pre-collision system does not function properly
The system may not function effectively in situations such as the following:
●On roads with sharp bends or uneven surfaces
●If a vehicle suddenly moves in front of your vehicle, such as at an inter-
section
●If a vehicle suddenly cuts in front of your vehicle, such as when overtak-
ing
●In inclement weather such as heavy rain, fog, snow or sand storms
●When your vehicle is skidding with the VSC system off
●When an extreme change in vehicle height occurs
●When the axis of the radar is out of adjustment
■Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in
the sensors being unable to detect obstacles, the pre-collision system will be
automatically disabled. In this case, the system will not activate even if there
is a collision possibility.
■When there is a malfunction in the system, or if the system is tempo-
rarily unusable
Warning lights and/or warning messages will turn on or flash. (→P. 5 3 8 , 5 5 0 )

Press and hold the tire pressure
warning reset switch until the tire
pressure warning light blinks
slowly 3 times.
Wait for a few minutes with the “POWER” switch in ON mode
and then turn the “POWER” switch off.
Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to register the ID code. Have the ID code
registered by your Toyota dealer.
