4-1. Before driving

WARNING

■

When taking a nap in the vehi-

cle

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 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

Do not spin the wheels exces-

sively when a driven wheel 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.

■

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.

■

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.

177

4-1. Before driving

ing

When the following unusual
operation is performed with the
accelerator pedal depressed,
the hybrid system output may be
restrained.
• When the shift lever is shifted

to R

• When the shift lever is shifted

from P or R to forward drive
shift position such as D

When the system operates, a mes-
sage appears on the multi-informa-
tion display. Read the message and
follow the instruction.

: Depending on the situation, the

shift position may not be
changed.

control also does not operate. If

your vehicle have trouble escaping

from the mud or fresh snow due to

sudden start restraint operation,

deactivate TRAC (



P.376) so that

the vehicle may become able to

escape from the mud or fresh snow.
Also, sudden start restraint control

will not operate in the following con-

ditions:

●

When the front-wheel drive control

switch is in “4H” or “4L” position.

(4WD models only)

●

When AUTO LSD mode, the drive

start control does not operate. (if

equipped)

●

When Multi-terrain Select is

selected. (if equipped)

NOTICE

■

If you get a flat tire while driv-

ing

A flat or damaged tire may cause

the following situations. Hold the

steering wheel firmly and gradu-

ally depress the brake pedal to

slow down the vehicle.

●

It may be difficult to control your

vehicle.

●

The vehicle will make abnormal

sounds or vibrations.

●

The vehicle will lean abnor-

mally.

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

becomes flooded or stuck in mud

or sand, be sure to have your Toy-

ota dealer check the following:

●

Brake function

●

Changes in quantity and quality

of oil and fluid used for the

engine, transmission, transfer

(4WD vehicles), differential, etc.

●

Cargo capacity depends on the
total weight of the occupants.
(Cargo capacity) = (Total load
capacity) — (Total weight of
occupants)
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.
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.

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

: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

:D =Additional weight of people

:E =Available cargo and luggage

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.

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 prevent the

pedals from being depressed

properly, may block the driver’s

vision, or may result in items hit-

ting the driver or passengers, pos-

sibly causing an accident.

●

Do not stack anything behind

the front seats 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.

●

Never allow anyone to ride in

the rear deck. It is not designed

for passengers. They should

ride in their seats with their seat

belts properly fastened. Other-

wise, they are much more likely

to suffer death or serious bodily

injury, in the event of sudden

braking, sudden swerving or an

accident.

■

Capacity and distribution

●

Do not exceed the maximum

axle weight rating or the total

vehicle weight rating.

WARNING

■

Overloading the vehicle

Do not overload the vehicle.

It may not only cause damage to

the tires, but also degrade steer-

ing and braking ability, resulting in

an accident.

Trailer towing

Your vehicle is designed pri-
marily as a passenger-and-
load-carrying vehicle. Tow-
ing a trailer can have an
adverse impact on handling,
performance, braking, dura-
bility, and fuel consumption.
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 prop-
erly, 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.

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.

Before towing

Check that the following conditions

are met:

●

Ensure that your vehicle’s tires

are properly inflated. (



P.547)

●

Trailer tires are inflated according

to the trailer manufacturer’s rec-

ommendation.

●

All trailer lights work as required

by law.

●

All lights work each time you con-

nect them.

●

The trailer ball is set at the proper

height for the coupler on the

trailer.

●

The trailer is level when it is

hitched. Do not drive if the trailer

is not level, and check for

improper tongue weight, overload-

ing, 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

appropriate for towing purposes.

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.

●

If the gross trailer weight is over

2000 lb. (900 kg), a sway con-

trol device with sufficient capac-

ity is required.

●

If the gross trailer weight is over

5000 lb. (2200 kg), a weight dis-

tributing hitch with sufficient

capacity 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.

183

4-1. Before driving

ing

WARNING

●

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 the following sys-

tems when your vehicles is tow-

ing a trailer or another vehicle.

• PCS (Pre-Collision System)

• Dynamic radar cruise control

with full-speed range

Except when the following condi-

tions are all met,

• When the other vehicle is a

trailer properly attached and

connected to Toyota’s official

TBC ECU.

• When the vehicle is not being

driven on a slippery surface

such as an icy road or a very

wet road.

●

Do not use the following sys-

tems when your vehicles is tow-

ing a trailer or another vehicle.

• Cruise control (if equipped)

• LTA (Lane Tracing Assist)

If the vehicle detects that a trailer

is being towed, the lane centering

function of LTA is automatically

turned off.

●

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 instability 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.

●

Do not tow a trailer when the

temporary spare tire is installed

on your vehicle.

■

When towing a trailer

Toyota recommends trailers with

brakes that conform to any appli-

cable federal and state/provincial

regulations.

●

If the gross trailer weight

exceeds unbraked TWR, trailer

brakes are required. Toyota rec-

ommends trailers with brakes

that conform to all applicable

federal and state/provincial reg-

ulations.

●

Never tap into your vehicle’s

hydraulic system, as this will

lower the vehicle’s braking

effectiveness.

●

Never tow a trailer without using

a safety chain securely attached

to both the trailer and the vehi-

cle. If damage occurs to the

coupling unit or hitch ball, there

is danger of the trailer wander-

ing into another lane.

If front axle weight cannot be mea-
sured directly, measure the front
fender height above the front axle
before connection. Adjust weight
distributing hitch torque until front

fender is returned to the same
height as before connection.
Do not reduce front fender height
below original measurement.
The gross trailer weight, gross axle
weight and tongue weight can be
measured with platform scales
found at a highway weighing sta-
tion, building supply company,

WARNING

■

Hitch

Trailer hitch assemblies have dif-

ferent weight capacities estab-

lished by the hitch manufacturer.

Even though the vehicle may be

physically capable of towing a

higher weight, the operator must

determine the maximum weight

rating of the particular hitch

assembly and never exceed the

maximum weight rating specified

for the trailer-hitch. Exceeding the

maximum weight rating set by the

trailer-hitch manufacturer can

cause an accident resulting in

death or serious personal injuries.
