pery.
●Drive carefully when it starts to
rain, as the road surface could be
especially slippery.
●Refrain from high speeds when
driving on an expressway in the
rain, because there may be a
layer of water between the tires
and the road surface, preventing
the steering and brakes from
operating properly.
■ECO Accelerator Guidance
(  P.108)
It is easier to drive in an Eco-friendly
manner by driving while referring to
the ECO Accelerator Guidance dis-
play. Also, by using the ECO Accel-
erator Guidance it is easier to
increase the “Eco Score” evaluation.
●When starting off:
While staying within the ECO
Accelerator Guidance range,
gradually depress the accelerator
pedal and accelerate to the
desired speed. If excessive accel-
eration is avoid ed, the “Start”
score will increase.
●When driving:
After accelerating to the desired
speed, release the accelerator
pedal and drive at a stable speed
within the ECO Acce lerator Guid-
ance range. By keeping the vehi-
cle within the E CO Accelerator
Guidance range, the “Cruise”
score will increase.
●When stopping:
When stopping the vehicle, early
releasing the accelerator pedal
will cause the “Stop” score to
increase.
■Restraining the hybrid system
output (Brake Override System)
●When the accelerator and brake
pedals are depressed at the same
time, the hybrid system output
may be restrained.
●A warning message is displayed
on the multi-information display
and head-up display (if equipped) while the system is operating.
(
 P.471)
■Restraining sudden start (Drive-
Start Control)
●When the following unusual oper-
ation is performed, the hybrid sys-
tem output may b e restrained.
• When the shift lever is shifted from
R to D, D to R, N to R, P to D
*, or
P to R* (D includes S) with the
accelerator pedal depressed, a
warning message appears on the
multi-information display and
head-up display (i f equipped). If a
warning message is shown on the
multi-information display and
head-up display (if equipped),
read the message and follow the
instructions.
• When the accelerator pedal is depressed too much while the
vehicle is in reverse.
*: Depending on the situation, the
shift position may not be changed.
●When the TRAC is turned off
( P.336), sudden start restraint
control also does not operate. If
your vehicle have trouble escap-
ing from the mud or fresh snow
due to the sudden start restraint
control operation, deactivate
TRAC( P.336) so that the vehi-
cle may become able to escape
from the mud o r fresh snow.
■Breaking in your new Toyota
To extend the life of the vehicle,
observing the following precautions
is recommended:
●For the first 200 miles (300 km):
Avoid sudden stops.
●For the first 500 miles (800 km):
Do not tow a trailer.
●For the first 600 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed

2104-1. Before driving
for extended periods.
■Operating your vehicle in a for-
eign country
Comply with the relevant vehicle
registration laws and confirm the
availability of the correct fuel.
(  P.520)
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
Vehicle Alerting System, drive
with care as pedestrians in the
vicinity may still not notice the
vehicle if the surrounding area
is noisy.
●Do not drive the vehicle over or
stop the vehicle near flammable
materials such as leaves, paper
or rags.
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 an
emergency, such as if it
becomes impossible to stop the
vehicle in the normal way:
 P.459
●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.

WARNING
■Trailer towing precautions
To tow a traile r safely, use
extreme care and drive the vehi-
cle in accordance with the trailer’s
characteristics and operating con-
ditions. Failure to do so could
cause an accident resulting in
death or serious injury. Vehicle
stability and braking performance
are affected by trailer stability,
brake setting and performance,
and the hitch. Your vehicle will
handle differently when towing a
trailer.
■To avoid accident or injury
●Do not exceed the TWR,
unbraked TWR, GCWR, GVWR
or GAWR.
●Vehicles without spare tire: Do
not tow a trailer when the tire
installed is re paired with the
emergency tire puncture repair
kit.
●If the gross trailer weight is over
2000 lb. (907 kg), a sway con-
trol device with sufficient capac-
ity is required.
●Adjust the tongue weight within
the appropriate range. Place
heavier loads as close to the
trailer axle as possible.
●Do not exceed 65 mph (104
km/h), the posted towing speed
limit or the speed limit for your
trailer as set fort h in your trailer
owner’s manual, whichever is
lowest. Slow down sufficiently
before making a turn, in cross
winds, on wet or slippery sur-
face, etc. to help avoid an acci-
dent. If you experience a
vehicle-trailer instability from
reducing a certain speed, slow
down and make sure you keep
your vehicle speed under the
speed of which you experience
the instability.
●Do not make jer ky, abrupt or
sharp turns.
●Do not apply the brakes sud-
denly as you may skid, resulting
in jackknifing and loss of vehicle
control. This is especially true
on wet or slippery surfaces.
●Do not exceed the trailer hitch
assembly weight, gross vehicle
weight, gross axle weight and
trailer tongue w eight capacities.
●Do not use dynamic radar
cruise control with full-speed
range when towing.
●Slow down and downshift
before descending steep or long
downhill grades. Do not make
sudden downshifts while
descending steep or long down-
hill grades.
●Vehicle-trailer in stability is more
likely on steep long downhills.
Before descending steep or
long downhill grades, slow
down and downshift. Do not
make sudden downshifts when
descending steep or long down-
hill grades. Avoid holding the
brake pedal down too long or
applying the brakes too fre-
quently. This could cause the
brakes to overheat and result in
reduced braking efficiency.
●Vehicles with compact spare
tire: Do not tow a trailer when
the compact spare tire is
installed on your vehicle.
■When towing a trailer
Toyota recommends trailers with
brakes that conform to any appli-
cable federal and s tate/provincial
regulations.

2274-1. Before driving

Driving
incorrect installation may cause
damage to the vehicle’s lights.
Please take care to comply with
your state’s laws when installing
trailer lights.
Your vehicle will handle differ-
ently when towing a trailer. Help
to avoid an accident, death or
serious injury, keep the follow-
ing in mind when towing:
Speed limits for towing a
trailer vary by state or prov-
ince. Do not exceed the
posted towing speed limit.
 Toyota recommends that the
vehicle-trailer speed limit is 65
mph (104 km/h) on a flat,
straight, dry road. Do not
exceed this limit, the posted
towing speed limit or the
speed limit for your trailer as
set forth in your trailer owner’s
manual, whichever is lowest.
Instability of the towing vehi-
cle-trailer combination (trailer
sway) increases as speed
increases. Exceeding speed
limits may cause loss of con-
trol. 
Before starting out, check the
trailer lights, tires and the
vehicle-trailer connections.
Recheck after driving a short
distance.
 Practice turning, stopping and
reversing with the trailer
attached in an area away
from traffic until you become
accustomed to the feel of the
vehicle-trailer combination.
 Reversing with a trailer
attached is difficult and
requires practice. Grip the
bottom of the steering wheel
and move your hand to the
left to move the trailer to the
left. Move your hand to the
right to move the trailer to the
right. (This is generally oppo-
site to reversing without a
trailer attached.) Avoid sharp
or prolonged turning. Have
someone guide you when
reversing to reduce the risk of
an accident.
 As stopping distance is
increased when towing a
trailer, vehicle-to vehicle dis-
tance should be increased.
For each 10 mph (16 km/h) of
speed, allow at least one
vehicle and trailer length.
 Avoid sudden braking as you
may skid, resulting in the
trailer jackknifing and a loss of
vehicle control. This is espe-
cially true on wet or slippery
surfaces.
NOTICE
■Do not directly splice trailer
lights
Do not directly splice trailer lights.
Directly splicing trailer lights may

help reduce the impact to the
occupants and the vehicle in the
case of a collision or assist the
driver in normal driving condi-
tions.
As there is a limit to the degree of
recognition accuracy and control
performance that this system can
provide, do not overly rely on this
system. The driver is always
responsible for paying attention to
the vehicle’s su rroundings and
driving safely.

2684-5. Using the driving support systems
WARNING
■Limitations of the pre-colli-
sion system
●The driver is solely responsible
for safe driving. Always drive
safely, taking care to observe
your surroundings.
Do not use the pre-collision sys-
tem instead of normal braking
operations under any circum-
stances. This system will not
prevent collisions or lessen col-
lision damage or injury in every
situation. Do not overly rely on
this system. Failure to do so
may lead to an accident, result-
ing in death or serious injury.
●Although this system is
designed to help avoid a colli-
sion or help reduce the impact
of the collision, its effectiveness
may change according to vari-
ous conditions, therefore the
system may not always be able
to achieve the same level of
performance.
Read the following conditions
carefully. Do not overly rely on
this system and always drive
carefully.
• Conditions under which the sys- tem may operate even if there is
no possibility of a collision:
 P.271
• Conditions under which the sys- tem may not operate properly:
 P.272
●Do not attempt to test the oper-
ation of the pre-collision system
yourself.
Depending on the objects used
for testing (dummies, card-
board objects imitating detect-
able objects, etc.), the system
may not operate properly, pos-
sibly leading to an accident.
■Pre-collision braking
●When the pre-collision braking
function is operating, a large
amount of braking force will be
applied.
●If the vehicle is stopped by the
operation of the pre-collision
braking function, the pre-colli-
sion braking function operation
will be canceled after approxi-
mately 2 seconds. Depress the
brake pedal as necessary.
●The pre-collision braking func-
tion may not operate if certain
operations are performed by the
driver. If the accelerator pedal is
being depressed strongly or the
steering wheel is being turned,
the system may determine that
the driver is taking evasive
action and possibly prevent the
pre-collision braking function
from operating.
●In some situations, while the
pre-collision brak ing function is
operating, operation of the func-
tion may be canceled if the
accelerator pedal is depressed
strongly or the steering wheel is
turned and the system deter-
mines that the driver is taking
evasive action.
●If the brake pedal is being
depressed, the system may
determine that t he driver is tak-
ing evasive action and possibly
delay the operation timing of the
pre-collision braking function.
■When to disable the pre-colli-
sion system
In the following situations, disable
the system, as it may not operate
properly, possibly leading to an
accident resulting in death or seri-
ous injury:
●When the vehicle is being towed
