EDR, special equipment is
required, and access to the
vehicle or the EDR is needed. In
addition to the vehicle manufac-
turer, other parties, such as law
enforcement, that have the spe-
cial equipment, can read the
information if they have access
to the vehicle or the EDR.
Disclosure of the EDR data
Toyota will not disclose the data
recorded in an EDR to a third party
except when:
• An agreement from the vehicle’s
owner (or the lessee for a leased
vehicle) is obtained
• In response to an official request by the police, a court of law or a
government agency
• For use by Toyota in a lawsuit
However, if necessary, Toyota may:
• Use the data for research on vehicle safety performance
• Disclose the data to a third party for research purposes without
disclosing information about the
specific vehicle or vehicle owner
The SRS airbag and seat belt
pretensioner devices in your
Toyota contain explosive chemi-
cals. If the vehicle is scrapped
with the airbags and seat belt
pretensioners left as they are,
this may cause an accident such
as fire. Be sure to have the sys-
tems of the SRS airbag and seat
belt pretensioner removed and disposed of by a qualified ser-
vice shop or by your Toyota
dealer before you scrap your
vehicle.
Special handling may apply, See
www.dtsc.ca.gov/hazard-
ouswaste/perchlorate.
Your vehicle has components
that may contain perchlorate.

WARNING
■General precautions while
driving
Driving under the influence: Never
drive your vehicle when under the
influence of alcohol or drugs that
have impaired your ability to oper-
ate your vehicle. Alcohol and cer-
tain drugs delay reaction time,
impair judgment and reduce coor-
dination, which could lead to an
accident that could result in death
or serious injury.
Defensive driving: Always drive
defensively. Anticipate mistakes
that other drivers or pedestrians
might make and be ready to avoid
accidents.
Driver distraction: Always give
your full attention to driving. Any-
thing that distracts the driver, such
as adjusting controls, talking on a
cellular phone or reading can
result in a collision with resulting
death or serious injury to you,
your occupants or others.

■If “Proximity Notification Sys-
tem Malfunction Visit Your
Dealer” is displayed on the
multi-information display
The system may be malfunctioning.
Have the vehicle inspected by your
Toyota dealer.
*: This function can only be used in
the mainland U.S.A. It cannot be
used in other states and territo-
ries, including Alaska and Hawaii.
This system operates based on
the driving situation and traffic
information to enhance fuel
economy.
For details about Predictive effi-
cient drive, refer to “NAVIGA-
TION AND MULTIMEDIA
SYSTEM OWNER’S MANUAL”.
■Predictive deceleration support
●When the vehicle approaches to
predictive deceleration support
points registered in the navigation
system, the zone of Eco accelera-
tion ( ) of the ECO Accelerator
Guidance ( P.103) on the
multi-information display will be
turned off to encourage the driver
to reduce excessive acceleration.
Example: 7-inch display
●The engine braki ng force will be
increased according to the driving
conditions to more efficiently
charge the hybrid battery (traction
battery) after the accelerator pedal
is released.
■Predictive SOC control
The following types of control are
performed based on data such as
road and traffic information during
route guidance by the navigation
system to help ensure that the vehi-
cle efficiently uses electricity.
●When there is a long downhill
slope along the r oute, the system
reduces the hybrid battery (trac-
tion battery) leve l before reaching
the slope to help ensure charging
capacity for regenerative braking
while traveling downhill.
●When traffic congestion is pre-
dicted along the route, the system
helps ensure a certain battery
level before reaching congested
roads to reduce the frequency of
starting the engin e to charge the
hybrid battery (traction battery)
due to low battery levels.

■Running out of fuel
When the vehicle has run out of fuel
and the hybrid system cannot be
started, refuel th e vehicle with at least enough gasoline to make the
low fuel level warning light (
P.469)
go off. If there is only a small
amount of fuel, the hybrid system
may not be able to start. (The stan-
dard amount of fuel is about 2.9 gal.
Hybrid system precautions
Take care when handling the hybrid system, as it is a high
voltage system (about 650 V at maximum) as well as contains
parts that become extremely hot when the hybrid system is
operating. Obey the warning labels attached to the vehicle.

■Operating your vehicle in a for-
eign country
Comply with the relevant vehicle
registration laws and confirm the
availability of the correct fuel.

WARNING
Observe the following precau-
tions.
Failure to do so m ay result in
death or serious injury.
■When starting the vehicle
Always keep your foot on the
brake pedal while stopped with
the “READY” indicator is illumi-
nated. This prevents the vehicle
from creeping.
■When driving the vehicle
●Do not drive if y ou are unfamil-
iar with the location of the brake
and accelerator pedals to avoid
depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the
brake pedal will result in sudden
acceleration that may lead to an
accident.
• When backing up, you may twist your body around, leading to a
difficulty in operating the pedals.
Make sure to operate the pedals
properly.
• Make sure to keep a correct driving posture even when mov-
ing the vehicle only slightly. This
allows you to depress the brake
and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the
brake pedal using your left foot
may delay respon se in an emer-
gency, resulting in an accident.
●The driver should pay extra
attention to pedestrians when
the vehicle is powered only by
the electric motor (traction
motor). As there is no engine
noise, the pedestrians may mis-
judge the vehicle’s movement.
Even though the vehicle is
equipped with the acoustic vehi-
cle alerting system, drive with
care as pedestrians in the vicin-
ity may still not n otice the vehi-
cle if the surrounding area is
noisy.
●Do not drive the vehicle over or
stop the vehicle near flammable
materials.
The exhaust system and
exhaust gases can be
extremely hot. These hot parts
may cause a fire i f there is any
flammable material nearby.
●During normal driving, do not
turn off the hybrid system. Turn-
ing the hybrid s ystem off while
driving will not cause loss of
steering or braking control, how-
ever, power assist to the steer-
ing will be lost. This will make it
more difficult to steer smoothly,
so you should pull over and stop
the vehicle as soon as it is safe
to do so.
In the event of a n emergency,
such as if it becomes impossible
to stop the vehicle in the normal
way:
P. 4 5 8
●Use engine braking (downshift)
to maintain a safe speed when
driving down a steep hill.
Using the brakes continuously
may cause the brakes to over-
heat and lose effectiveness.
(
P.220)
●Do not adjust the positions of
the steering wheel, the seat, or
the inside or outside rear view
mirrors while driving.
Doing so may result in a loss of
vehicle control.

2204-2. Driving procedures
HIGHLANDER HV_U
*1: To improve fuel efficiency and reduce noise, shift the shift lever
to D for normal driving.
*2: By selecting shift ranges using S mode, you can control accelerat-
ing force and engine braking
force.
■When driving with dynamic
radar cruise control with
full-speed range activated
Even when switching the driving
mode to sport mode with the intent
of enabling engine braking, engine
braking will not act ivate because
dynamic radar cruise control with
full-speed range will not be can-
celed.

WARNING
■When driving on slippery
road surfaces
Be careful of downshifting and
sudden acceleration, as this could
result in the vehicle skidding to
the side or spinning.
NOTICE
■Hybrid battery (traction bat-
tery) charge
If the shift lever is in N, the hybrid
battery (traction battery) will not
be charged even when the engine
is running. Therefore, if the vehi-
cle is left with the shift lever in N
for a long period of time, the
hybrid battery (traction battery)
will discharge, and this may result
in the vehicle not being able to
start.

■ECB (Electronically Con-
trolled Brake System)
The electronically controlled
system generates braking force
corresponding to the brake
operation
■ABS (Anti-lock Brake Sys-
tem)
Helps to prevent wheel lock
when the brakes are applied
suddenly, or if the brakes are
applied while driving on a slip-
pery road surface
■Brake assist
Generates an increased level of
braking force after the brake
pedal is depressed when the
system detects a panic stop sit-
uation
■VSC (Vehicle Stability Con-
trol)
Helps the driver to control skid-
ding when swerving suddenly or
turning on slippery road sur-
faces
■Enhanced VSC (Enhanced
Vehicle Stability Control)
Provides cooperative control of
the ABS, TRAC, VSC and EPS.
Helps to maintain directional
stability when swerving on slip-
pery road surfaces by con-
trolling steering performance.
■Trailer Sway Control
Helps the driver to control trailer
sway by selectively applying
brake pressure for individual
wheels and reducing driving
torque when trailer sway is
detected.
■TRAC (Traction Control)
Helps to maintain drive power
and prevent the drive wheels
from spinning when starting the
vehicle or accelerating on slip-
pery roads
■Active Cornering Assist
(ACA)
Helps to prevent the vehicle
from drifting to the outer side by
performing inner wheel brake
control when attempting to
accelerate while turning
■Hill-start assist control
Helps to reduce the backward
movement of the vehicle when
Driving assist systems
To keep driving safety and
performance, the following
systems operate automati-
cally in response to various
driving situations. Be
aware, however, that these
systems are supplementary
and should not be relied
upon too heavily when oper-
ating the vehicle.
Summary of the driving
assist systems

HIGHLANDER HV_U
starting on an uphill
■EPS (Electric Power Steer-
ing)
Employs an electric motor to
reduce the amount of effort
needed to turn the steering
wheel
■E-Four
Electronic On-Demand AWD
system. Automatically switches
from front-wheel drive to
all-wheel drive (AWD) according
to the driving conditions, helping
to ensure reliable handling and
stability. Examples of conditions
where the system will switch to
AWD are when cornering, going
uphill, starting off or accelerat-
ing, and when the road surface
is slippery due to snow, rain, etc.
■VDIM (Vehicle Dynamics
Integrated Management)
Provides integrated control of
the ABS, brake assist, TRAC,
VSC, hill-start assist control and
EPS systems
Helps to maintain vehicle stabil-
ity when swerving on slippery
road surfaces by controlling the
brakes, hybrid system output
and steering assist.
■The Secondary Collision
Brake
When the SRS airbag sensor
detects a collision and the sys-
tem operates, the brakes and
brake lights are automatically
controlled to reduce the vehicle speed and help reduce the pos-
sibility of further damage due to
a secondary collision.
■When the
TRAC/VSC/ABS/Trailer Sway
Control systems
are operating
The slip indicator light will flash
while the TRAC/VSC/ABS/Trailer
Sway Control systems are operat-
ing.
■Disabling the TRAC system
If the vehicle gets stuck in mud, dirt
or snow, the TRAC system may
reduce power from the hybrid sys-
tem to the wheels. Pressing the
switch to turn th e system off may
make it easier for you to rock the
vehicle in order to free it.
To turn the TRAC system off, quickly
press and release the switch.
The “Traction Cont rol Turned OFF”
will be shown on the multi-informa-
tion display.
Press the switch again to turn
the system back on.
