●When any part of the vehicle sags
When any part of the vehicle
sags due to the number of pas-
sengers or the distribution of
the load, there is a margin of
error between the fixed guide
lines on the screen and the
actual distance/course on the
road.
■When approaching thre e-dimensional objects
The distance guide lines are displayed according to flat surfaced
objects (such as the road). It is not possible to determine the posi-
tion of three-dimensional objects (such as vehicles) using the dis-
tance guide lines. When approaching a three-dimensional object
that extends outward (such as the flatbed of a truck), be careful of
the following.
● Distance guidelines
Visually check the surroundings
and the area behind the vehi-
cle. On the screen, it appears
that a truck is parked at point
. However, in reality if you
back up to point , you will hit
the truck. On the screen, it
appears that is closest and is farthest away. However,
in reality, the distance to
and is the same, and is
farther than and .

Vehicle width guide lines
Visually check the surroundings and
the area behind the vehicle. In
the case shown below, the truck appears to be outside of the vehi-
cle width guide lines and the vehicle does not look as if it hits the
truck. However, the rear body of the truck may actually cross over
the vehicle width guide lines. In reality if you back up as guided by
the vehicle width guide lines, the vehicle may hit the truck.

WARNING
■When using the rear view monitor system
The rear view monitor system is a supplemental device intended to assist
the driver when backing up. When backing up, be sure to visually check all
around the vehicle both directly and using the mirrors before proceeding. If
you do not, you may hit another vehicle, and could possibly cause an acci-
dent.
Pay attention to the following precautions when using the rear view moni\
tor
system.
● Never depend on the rear view monitor system entirely when backing up.
The image and the position of the guide lines displayed on the screen may
differ from the actual state.
Use caution, just as you would when backing up any vehicle.
● Be sure to back up slowly, depressing the brake pedal to control vehicle
speed.
● The instructions given are only guidelines.
When and how much to turn the steering wheel will vary according to traf-
fic conditions, road surface conditions, vehicle condition, etc. when park-
ing. It is necessary to be fully aware of this before using the rear view
monitor system.
● When parking, be sure to check that the parking space will accommodate
your vehicle before maneuvering into it.
● Do not use the rear view monitor system in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or the compact spare tire
• When the back door is not closed completely
• On roads that are not flat or straight, such as curves or slopes.
● In low temperatures, the screen may darken or the image may become
faint. The image could distort when the vehicle is moving, or you may
become unable to see the image on the screen. Be sure to visually check
all around the vehicle both directly and using the mirrors before proceed-
ing.
● If the tire sizes are changed, the position of the fixed guide lines displayed
on the screen may change.
● The camera uses a special lens. The distances between objects and
pedestrians that appear in the image displayed on the screen will differ
from the actual distances. ( →P. 259)

NOTICE
■How to use the camera
● The rear view monitor system may not operate properly in the following
cases.
• If the back of the vehicle is hit, the position and mounting angle of the
camera may change.
• As the camera has a water proof construction, do not detach, disassem- ble or modify it. This may cause incorrect operation.
• When cleaning the camera lens, flush the camera with a large quantity of water and wipe it with a soft and wet cloth. Strongly rubbing the cam-
era lens may cause the camera lens to be scratched and unable to
transmit a clear image.
• Do not allow organic solvent, car wax, window cleaner or glass coating to adhere to the camera. If this happens, wipe it off as soon as possible.
• If the temperature changes rapidly, such as when hot water is poured on the vehicle in cold weather, the system may not operate normally.
• When washing the vehicle, do not apply intensive bursts of water to the
camera or camera area. Doing so may result in the camera malfunc-
tioning.
● Do not expose the camera to strong impact as this could cause a malfunc-
tion. If this happens, have the vehicle inspected by your Toyota dealer as
soon as possible.

◆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
◆TRAC (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
Helps to reduce the backward move ment of the vehicle when start-
ing on an uphill
◆EPS (Electric Power Steering)
Employs an electric motor to redu ce the amount of effort needed to
turn the steering wheel
Driving assist systems
To keep driving safety and perf ormance, the following systems
operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too he avily when operating the vehi-
cle.

ing that TRAC has been disable d even if has not been pressed
TRAC cannot be operated. Contact your Toyota dealer.
■ 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

● The shift lever is shifted to P or N
● The accelerator pedal is depressed
● The parking brake is engaged
● 2 seconds at maximum elapsed after the brake pedal is released
■ Sounds and vibrations caused by the ABS, brake assist, VSC, TRAC and
hill-start assist control systems
●A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, when the hybrid system is started or just after the
vehicle begins to move. 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.

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.
■ 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.
■ Electric power steering system warning light (warning buzzer)
→P. 486
■ Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
● When the power switch is turned to the “LOCK” position (vehicles without a
smart key system) or the power switch is turned off (vehicles with a smart
key system)
● If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling 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 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 uneven surfaces
■ TRAC/VSC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC/VSC system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.
■ Hill-start assist control does not operate effectively when
● Do not overly rely on hill-start assist control. 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 TRAC/ABS /VSC are 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 TRAC/VSC syst ems 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 TRAC/VSC systems off unless necessary.
