ing

up, and the road could be slip-

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 avoided, 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 Accelerator Guid-

ance range. By keeping the vehi-

cle within the ECO 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.469)

■

Restraining sudden start (Drive-

Start Control)

●

When the following unusual oper-

ation is performed, the hybrid sys-

tem output may be 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 (if 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.337), 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.337) so that the vehi-

cle may become able to escape

from the mud or 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.

212

4-1. Before driving

• Do not drive at a constant speed

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.518)

WARNING

Observe the following precau-

tions.

Failure to do so may 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 you 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 response 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 if there is any

flammable material nearby.

●

During normal driving, do not

turn off the hybrid system. Turn-

ing the hybrid system 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.457

●

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.241)

213

4-1. Before driving

ing

WARNING

●

Do not adjust the position of the

steering wheel, the seat, or the

inside or outside rear view mir-

rors while driving.

Doing so may result in a loss of

vehicle control.

●

Always check that all passen-

gers’ arms, head or other parts

of their body are not outside the

vehicle.

●

AWD models: Do not drive the

vehicle off-road. This is not an

AWD vehicle designed for off-

road driving. Drive with due care

if it becomes unavoidable to

drive off-road.

●

AWD models: Do not drive

across a river or through other

bodies of water. This may cause

electric/electronic components

to short circuit, damage the

engine or cause other serious

damage to the vehicle.

●

Do not drive in excess of the

speed limit. Even if the legal

speed limit permits it, do not

drive over 85 mph (140 km/h)

unless your vehicle has high-

speed capability tires. Driving

over 85 mph (140 km/h) may

result in tire failure, loss of con-

trol and possible injury. Be sure

to consult a tire dealer to deter-

mine whether the tires on your

vehicle are high-speed capabil-

ity tires or not before driving at

such speeds.

■

When driving on slippery

road surfaces

●

Sudden braking, acceleration

and steering may cause tire

slippage and reduce your ability

to control the vehicle.

●

Sudden acceleration, engine

braking due to shifting, or

changes in engine speed could

cause the vehicle to skid.

●

After driving through a puddle,

lightly depress the brake pedal

to make sure that the brakes

are functioning properly. Wet

brake pads may prevent the

brakes from functioning prop-

erly. If the brakes on only one

side are wet and not functioning

properly, steering control may

be affected.

■

When shifting the shift lever

●

Do not let the vehicle roll back-

ward while a forward driving

position is selected, or roll for-

ward while the shift lever is in R.

Doing so may result in an acci-

dent or damage to the vehicle.

●

Do not shift the shift lever to P

while the vehicle is moving.

Doing so can damage the trans-

mission and may result in a loss

of vehicle control.

●

Do not shift the shift lever to R

while the vehicle is moving for-

ward.

Doing so can damage the trans-

mission and may result in a loss

of vehicle control.

●

Do not shift the shift lever to a

driving position while the vehicle

is moving backward.

Doing so can damage the trans-

mission and may result in a loss

of vehicle control.

●

Moving the shift lever to N while

the vehicle is moving will disen-

gage the hybrid system. Engine

braking is not available with the

hybrid system disengaged.

214

4-1. Before driving

WARNING

●

Be careful not to shift the shift

lever with the accelerator pedal

depressed.

Shifting the shift lever to a gear

other than P or N may lead to

unexpected rapid acceleration

of the vehicle that may cause an

accident and result in death or

serious injury. Doing so can

damage the transmission and

may result in a loss of vehicle

control.

■

If you hear a squealing or

scraping noise (brake pad

wear limit indicators)

Have the brake pads checked and

replaced by your Toyota dealer as

soon as possible.

Rotor damage may result if the

pads are not replaced when

needed.

It is dangerous to drive the vehicle

when the wear limits of the brake

pads and/or those of the brake

discs are exceeded.

■

When the vehicle is stopped

●

Do not depress the accelerator

pedal unnecessarily.

If the vehicle is in any gear other

than P or N, the vehicle may

accelerate suddenly and unex-

pectedly, causing an accident.

●

In order to prevent accidents

due to the vehicle rolling away,

always keep depressing the

brake pedal while stopped with

the “READY” indicator is illumi-

nated, and apply the parking

brake as necessary.

●

If the vehicle is stopped on an

incline, in order to prevent acci-

dents caused by the vehicle roll-

ing forward or backward, always

depress the brake pedal and

securely apply the parking

brake as needed.

●

Avoid revving or racing the

engine.

Running the engine at high

speed while the vehicle is

stopped may cause the exhaust

system to overheat, which could

result in a fire if combustible

material is nearby.

■

When the vehicle is parked

●

Do not leave glasses, cigarette

lighters, spray cans, or soft

drink cans in the vehicle when it

is in the sun.

Doing so may result in the fol-

lowing:

• Gas may leak from a cigarette

lighter or spray can, and may

lead to a fire.

• The temperature inside the

vehicle may cause the plastic

lenses and plastic material of

glasses to deform or crack.

• Soft drink cans may fracture,

causing the contents to spray

over the interior of the vehicle,

and may also cause a short cir-

cuit in the vehicle’s electrical

components.

●

Do not leave cigarette lighters in

the vehicle. If a cigarette lighter

is in a place such as the glove

box or on the floor, it may be lit

accidentally when luggage is

loaded or the seat is adjusted,

causing a fire.

●

Do not attach adhesive discs to

the windshield or windows. Do

not place containers such as air

fresheners on the instrument

panel or dashboard. Adhesive

discs or containers may act as

lenses, causing a fire in the

vehicle.

215

4-1. Before driving

ing

WARNING

●

Do not leave a door or window

open if the curved glass is

coated with a metallized film

such as a silver-colored one.

Reflected sunlight may cause

the glass to act as a lens, caus-

ing a fire.

●

Always apply the parking brake,

shift the shift lever to P, stop the

hybrid system and lock the vehi-

cle.

Do not leave the vehicle unat-

tended while the “READY” indi-

cator is illuminated.

If the vehicle is parked with the

shift lever in P but the parking

brake is not set, the vehicle may

start to move, possibly leading

to an accident.

●

Do not touch the exhaust pipes

while the “READY” indicator is

illuminated or immediately after

turning the hybrid system off.

Doing so may cause burns.

■

When taking a nap in the

vehicle

Always turn the hybrid system off.

Otherwise, if you accidentally

move the shift lever or depress

the accelerator pedal, this could

cause an accident or fire due to

hybrid system overheating. Addi-

tionally, if the vehicle is parked in

a poorly ventilated area, exhaust

gases may collect and enter the

vehicle, leading to death or a seri-

ous health hazard.

■

When braking

●

When the brakes are wet, drive

more cautiously.

Braking distance increases

when the brakes are wet, and

this may cause one side of the

vehicle to brake differently than

the other side. Also, the parking

brake may not securely hold the

vehicle.

●

If the electronically controlled

brake system does not operate,

do not follow other vehicles

closely and avoid hills or sharp

turns that require braking.

In this case, braking is still pos-

sible, but the brake pedal

should be depressed more

firmly than usual. Also, the brak-

ing distance will increase. Have

your brakes fixed immediately.

●

The brake system consists of 2

or more individual hydraulic sys-

tems; if one of the systems fails,

the other will still operate. In this

case, the brake pedal should be

depressed more firmly than

usual and the braking distance

will increase. Have your brakes

fixed immediately.

■

If the vehicle becomes stuck

(AWD models)

Do not spin the wheels exces-

sively when any of the tires is up

in the air, or the vehicle is stuck in

sand, mud, etc. This may damage

the driveline components or pro-

pel the vehicle forward or back-

ward, causing an accident.

NOTICE

■

When driving the vehicle

●

Do not depress the accelerator

and brake pedals at the same

time during driving, as this may

restrain the hybrid system out-

put.

●

Do not use the accelerator

pedal or depress the accelera-

tor and brake pedals at the

same time to hold the vehicle on

a hill.

216

4-1. Before driving

NOTICE

■

Avoiding damage to vehicle

parts

●

Do not turn the steering wheel

fully in either direction and hold

it there for an extended period

of time.

Doing so may damage the

power steering motor.

●

When driving over bumps in the

road, drive as slowly as possible

to avoid damaging the wheels,

underside of the vehicle, etc.

■

If you get a flat tire while driv-

ing

A flat or damaged tire may cause

the following situations.

●

It may be difficult to control your

vehicle.

●

The vehicle will make abnormal

sounds or vibrations.

●

The vehicle will lean abnor-

mally.

Hold the steering wheel firmly and

gradually depress the brake pedal

to slow down the vehicle.
Information on what to do in case

of a flat tire (



P.480, 490)

■

When encountering flooded

roads

Do not drive on a road that has

flooded after heavy rain, etc.

Doing so may cause the following

serious damage to the vehicle:

●

Engine stalling

●

Short in electrical components

●

Engine damage caused by

water immersion

In the event that you drive on a

flooded road and the vehicle is

flooded, be sure to have your

Toyota dealer check the following:

●

Brake function

●

Changes in quantity and quality

of oil and fluid used for the

engine, hybrid transmission

(front and rear), etc.

●

Lubricant condition for the bear-

ings and suspension joints

(where possible), and the func-

tion of all joints, bearings, etc.

■

When parking the vehicle

Always set the parking brake, and

shift the shift lever to P. Failure to

do so may cause the vehicle to

move or the vehicle may acceler-

ate suddenly if the accelerator

pedal is accidentally depressed.

217

4-1. Before driving

ing

Cargo capacity depends on the
total weight of the occupants.
(Cargo capacity) = (Total load
capacity) - (Total weight of occu-
pants)

Steps for Determining Correct
Load Limit



(1) Locate the statement “The
combined weight of occupants
and cargo should never exceed
XXX kg or XXX lbs.” on your
vehicle’s placard.
(2) Determine the combined
weight of the driver and passen-
gers that will be riding in your
vehicle.
(3) Subtract the combined
weight of the driver and passen-
gers from XXX kg or XXX lbs.
(4) The resulting figure equals
the available amount of cargo
and luggage load capacity.

Cargo and luggage

Take notice of the following
information about storage
precautions, cargo capacity
and load.

WARNING

■

Things that must not be car-

ried in the luggage compart-

ment

The following things may cause a

fire if loaded in the luggage com-

partment:

●

Receptacles containing gaso-

line

●

Aerosol cans

■

Storage precautions

Observe the following precau-

tions. Failure to do so may pre-

vent the pedals from being

depressed properly, may block

the driver’s vision, or may result in

items hitting the driver or passen-

gers, possibly causing an acci-

dent.

●

Stow cargo and luggage in the

luggage compartment when-

ever possible.

●

Do not stack anything in the lug-

gage compartment higher than

the seatbacks.

●

Do not place cargo or luggage

in or on the following locations.

• At the feet of the driver
• On the front passenger or rear

seats (when stacking items)

• On the instrument panel
• On the dashboard
• On the auxiliary box or tray that

has no lid

●

Secure all items in the occupant

compartment.

●

When you fold down the rear

seats, long items should not be

placed directly behind the front

seats.

●

Never allow anyone to ride in

the luggage compartment. It is

not designed for passengers.

They should ride in their seats

with their seat belts properly

fastened. Otherwise, they are

much more likely to suffer death

or serious bodily injury, in the

event of sudden braking, sud-

den swerving or an accident.

Capacity and distribution

218

4-1. Before driving

For example, if the “XXX”
amount equals 1400 lbs. and
there will be five 150 lb passen-
gers in your vehicle, the amount
of available cargo and luggage
load capacity is 650 lbs. (1400 -
750 (5



150) = 650 lbs.)

(5) Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
exceed the available cargo and
luggage load capacity calcu-
lated in Step 4.
(6) If your vehicle will be towing
a trailer, load from your trailer
will be transferred to your vehi-
cle. Consult this manual to
determine how this reduces the
available cargo and luggage
load capacity of your vehicle.
(



P.220)

Cargo capacity

Total load capacity (vehicle
capacity weight) (



P.516)

When 2 people with the com-
bined weight of A lb. (kg) are rid-
ing in your vehicle, which has a
total load capacity (vehicle
capacity weight) of B lb. (kg),
the available amount of cargo
and luggage load capacity will
be C lb. (kg) as follows:

lb. (kg) - A

lb. (kg) = C

lb.

(kg)

:A = Weight of people

:B = Total load capacity

:C = Available cargo and luggage

load

In this condition, if 3 more passen-
gers with the combined weight of D
lb. (kg) get on, the available cargo
and luggage load will be reduced E
lb. (kg) as follows:

C lb. (kg) - D

lb. (kg) = E

lb.

(kg)

:D = Additional weight of people

:E = Available cargo and luggage

WARNING

■

Capacity and distribution

●

Do not exceed the maximum

axle weight rating or the total

vehicle weight rating.

●

Even if the total load of occu-

pant’ weight and the cargo load

is less than the total load capac-

ity, do not apply the load

unevenly. Improper loading may

cause deterioration of steering

or braking control which may

cause death or serious injury.

Calculation formula for
your vehicle

219

4-1. Before driving

ing

load

As shown in the example above,
if the number of occupants
increases, the cargo and lug-
gage load will be reduced by an
amount that equals the
increased weight due to the
additional occupants. In other
words, if an increase in the num-
ber of occupants causes an
excess of the total load capacity
(combined weight of occupants
plus cargo and luggage load),
you must reduce the cargo and
luggage on your vehicle.

Roof luggage carrier (if
equipped)

WARNING

■

When loading cargo on the

roof luggage carrier

To use the roof rails as a roof lug-

gage carrier, you must fit the roof

rails with two or more genuine

Toyota cross rails or their equiva-

lent. When you load cargo on the

roof luggage carrier, observe the

following:

●

Place the cargo so that its

weight is distributed evenly

between the front and rear

axles.

●

If loading long or wide cargo,

never exceed the vehicle overall

length or width. (



P.516)

●

Before driving, make sure the

cargo is securely fastened on

the roof luggage carrier.

●

Loading cargo on the roof lug-

gage carrier will make the cen-

ter of gravity of the vehicle

higher. Avoid high speeds, sud-

den starts, sharp turns, sudden

braking or abrupt maneuvers,

otherwise it may result in loss of

control or vehicle rollover due to

failure to operate this vehicle

correctly and result in death or

serious injury.

●

If driving for a long distance, on

rough roads, or at high speeds,

stop the vehicle now and then

during the trip to make sure the

cargo remains in its place.

●

Do not exceed 150 lb. (68 kg)

cargo weight on the roof lug-

gage carrier. Place the cargo so

that its weight is distributed

evenly between both cross rails.

tongue weight, overloading, worn

suspension, or other possible

causes.

●

The trailer cargo is securely

loaded.

●

The rear view mirrors conform to

all applicable federal, state/provin-

cial or local regulations. If they do

not, install rear view mirrors

Trailer towing (with

towing package)

Your vehicle is designed
primarily as a passenger-
and-load-carrying vehicle.
Towing a trailer can have an
adverse impact on handling,
performance, braking, dura-
bility, and fuel consump-
tion. For your safety and the
safety of others, you must
not overload your vehicle or
trailer. You must also
ensure that you are using
appropriate towing equip-
ment, that the towing equip-
ment has been installed
correctly and used properly,
and that you employ the
requisite driving habits.

Vehicle-trailer stability and
braking performance are
affected by trailer stability,
brake performance and set-
ting, trailer brakes, the hitch
and hitch systems (if
equipped).

To tow a trailer safely, use
extreme care and drive the
vehicle in accordance with
your trailer’s characteris-
tics and operating condi-
tions.

Toyota warranties do not
apply to damage or mal-
function caused by towing a
trailer for commercial pur-
poses.

Contact your Toyota dealer for
further information about addi-
tional requirements such as a
towing kit, etc.

WARNING

■

Trailer towing precautions

To tow a trailer 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 repaired 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 forth 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 jerky, 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 weight 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.
