P.284)

■

Driving in the rain

●

Drive carefully when it is raining, because

visibility will be reduced, the windows

may become fogged-up, and the road

will be slippery.

●

Drive carefully when it starts to rain,

because the road surface will be espe-

cially slippery.

●

P.454)

■

Eco-friendly driving



P.85

WARNING

Observe the following precautions.

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 illuminated. This prevents the

vehicle from creeping.

■

When driving the vehicle

●

Do not drive if you are unfamiliar with

the location of the brake and accelera-

tor pedals to avoid depressing the

wrong pedal.

• Accidentally depressing the accelera-

tor 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 moving 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 emergency, 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 misjudge

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.

164

4-1. Before driving

WARNING

●

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 if there is any flamma-

ble material nearby.

●

During normal driving, do not turn off

the hybrid system. Turning the hybrid

system off while driving will not cause

loss of steering or braking control,

however, power assist to the steering

will be lost. This will make it more diffi-

cult 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 vehi-

cle in the normal way:



P.402

●

Use engine braking (downshift) to

maintain a safe speed when driving

down a steep hill.

Using the brakes continuously may

cause the brakes to overheat and lose

effectiveness. (



P.189)

●

Do not adjust the positions of the

steering wheel, the seat, or the inside

or outside rear view mirrors while driv-

ing.

Doing so may result in a loss of vehicle

control.

●

Always check that all passengers’

arms, heads or other parts of their

body are not outside the vehicle.

●

Do not drive the vehicle off-road.

This is not an AWD vehicle designed

for off-road driving. Proceed with all

due caution if it becomes unavoidable

to drive off-road.

●

Do not drive across a river or through

other bodies of water.

This may cause electric/electronic

components to short circuit, damage

the hybrid system or cause other seri-

ous damage to the vehicle.

●

Do not drive in excess of the speed

limit. Even if the legal speed limit per-

mits 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 control and possible

injury. Be sure to consult a tire dealer

to determine whether the tires on your

vehicle are high-speed capability tires

or not before driving at such speeds.

■

When driving on slippery road sur-

faces

●

Sudden braking, acceleration and

steering may cause tire slippage and

reduce your ability to control the vehi-

cle.

●

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 prop-

erly. Wet brake pads may prevent the

brakes from functioning properly. If the

brakes on only one side are wet and

not functioning properly, steering con-

trol may be affected.

■

When shifting the shift lever

●

Do not let the vehicle roll backward

while a forward driving position is

selected, or roll forward while the shift

lever is in R.

Doing so may result in an accident or

damage to the vehicle.

●

Do not shift the shift lever to P while

the vehicle is moving.

Doing so can damage the transmission

and may result in a loss of vehicle con-

trol.

●

Do not shift the shift lever to R while

the vehicle is moving forward.

Doing so can damage the transmission

and may result in a loss of vehicle con-

trol.

165

4-1. Before driving

Driving

WARNING

●

Do not shift the shift lever to a driving

position while the vehicle is moving

backward.

Doing so can damage the transmission

and may result in a loss of vehicle con-

trol.

●

Shifting the shift lever to N while the

vehicle is moving will disengage the

hybrid system. Engine braking is not

available when N is selected.

●

Be careful not to shift the shift lever

with the accelerator pedal depressed.

Shifting the shift lever to any position

other than P or N may lead to unex-

pected rapid acceleration of the vehi-

cle that may cause an accident and

result in death or serious injury.

■

If you hear a squealing or scraping

noise (brake pad wear limit indica-

tors)

Have the brake pads checked and

replaced by your Lexus 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 shift lever is in any position other

than P or N, the vehicle may acceler-

ate suddenly and unexpectedly, caus-

ing 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

illuminated, and apply the parking

brake as necessary.

●

If the vehicle is stopped on an incline,

in order to prevent accidents caused

by the vehicle rolling forward or back-

ward, 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 following:

• 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 plas-

tic 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 circuit 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.

●

Do not leave a door or window open if

the curved glass is coated with a met-

allized film such as a silver-colored

one. Reflected sunlight may cause the

glass to act as a lens, causing a fire.

166

4-1. Before driving

WARNING

●

Always apply the parking brake, shift

the shift lever to P, stop the hybrid sys-

tem and lock the vehicle.

Do not leave the vehicle unattended

while the “READY” indicator is illumi-

nated.

If the vehicle is parked with the shift

lever in P but the parking brake is not

set, the vehicle may start to move, pos-

sibly 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. Other-

wise, if you accidentally move the shift

lever or depress the accelerator pedal,

this could cause an accident or fire due

to hybrid system overheating. Addition-

ally, if the vehicle is parked in a poorly

ventilated area, exhaust gases may col-

lect and enter the vehicle, leading to

death or a serious 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 vehi-

cle.

●

If the electronically controlled brake

function does not operate, do not fol-

low other vehicles closely and avoid

hills or sharp turns that require brak-

ing.

In this case, braking is still possible, 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 systems; if one of

the systems fails, the other(s) 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 excessively when

any of the tires is up in the air, or the vehi-

cle is stuck in sand, mud, etc. This may

damage the driveline components or

propel the vehicle forward or backward,

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 output.

●

Do not use the accelerator pedal or

depress the accelerator 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 accelerate suddenly if the accelera-

tor 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 on the road,

drive as slowly as possible to avoid

damaging the wheels, underside of the

vehicle, etc.

Cargo capacity depends on the total
weight of the occupants.
(Cargo capacity) = (Total load capac-
ity) — (Total weight of occupants)
Steps for Determining Correct Load
Limit —
(1) Locate the statement “The com-
bined 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 passengers that will be
riding in your vehicle.
(3) Subtract the combined weight of
the driver and passengers 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 passengers in your vehicle, the
amount of available cargo and luggage
load capacity is 650 lbs. (1400

−

750



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 lug-

NOTICE

■

If you get a flat tire while driving

A flat or damaged tire may cause the fol-

lowing situations. Hold the steering

wheel firmly and gradually depress the

brake pedal to slow down the vehicle.

●

It may be difficult to control your vehi-

cle.

●

The vehicle will make abnormal

sounds or vibrations.

●

The vehicle will lean abnormally.

■

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 vehi-

cle:

●

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 Lexus dealer check the fol-

lowing:

●

Brake function

●

Changes in quantity and quality of oil

and fluid used for the engine, hybrid

transmission, rear differential, etc.

●

Lubricant condition for bearings and

suspension joints (where possible),

and the function of all joints, bearings,

etc.

Cargo and luggage

Take notice of the following infor-
mation about storage precautions,
cargo capacity and load.

Capacity and distribution

4-1. Before driving

gage load capacity calculated in Step
4.
(6) If your vehicle will be towing a
trailer, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and lug-
gage load capacity of your vehicle.
(

P.170)

Vehicles without towing package: Lexus
does not recommend towing a trailer with
your vehicle. Your vehicle is not designed
for trailer towing.

Cargo capacity
Total load capacity (vehicle capac-
ity weight) (



P.452)

When 2 people with the combined
weight of A lb. (kg) are riding in your
vehicle, which has a total load capacity
(vehicle capacity weight) of B lb. (kg),
the available amount of cargo and lug-
gage 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 passengers 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 load

As shown in the example above, if the
number of occupants increases, the
cargo and luggage 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 number of occupants
causes an excess of the total load
capacity (combined weight of occu-
pants plus cargo and luggage load),
you must reduce the cargo and lug-
gage on your vehicle.

WARNING

■

Things that must not be carried in the

luggage compartment

The following things may cause a fire if

loaded in the luggage compartment:

●

Receptacles containing gasoline

●

Aerosol cans

■

Storage precautions

Observe the following precautions.

Failure to do so may prevent the pedals

from being depressed properly, may

block the driver’s vision, or may result in

items hitting the driver or passengers,

possibly causing an accident.

●

Stow cargo and luggage in the lug-

gage compartment whenever possi-

ble.

Driving

WARNING

●

Do not stack cargo and luggage in the

luggage compartment higher than the

seatbacks.

●

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 lug-

gage compartment. It is not designed

for passengers. They should ride in

their seats with their seat belts prop-

erly fastened.

●

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 luggage cover

• On the instrument panel

• On the dashboard

●

Secure all items in the occupant com-

partment.

■

Capacity and distribution

●

Do not exceed the maximum axle

weight rating or the total vehicle

weight rating.

●

Even if the total load of occupant’s

weight and the cargo load is less than

the total load capacity, do not apply the

load unevenly. Improper loading may

cause deterioration of steering or

braking control which may cause

death or serious injury.

■

Roof luggage carrier precautions

Observe the following precautions:

●

Place the cargo so that its weight is dis-

tributed evenly between the front and

rear axles.

●

If loading long or wide cargo, never

exceed the vehicle overall length or

width. (



P.452)

●

Before driving, make sure the cargo is

securely fastened on the roof luggage

carrier.

●

Loading cargo on the roof luggage

carrier will make the center of gravity

of the vehicle higher. Avoid high

speeds, sudden starts, sharp turns,

sudden braking or abrupt maneuvers,

otherwise it may result in loss of con-

trol 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 vehi-

cle now and then during the trip to

make sure the cargo remains in its

place.

●

Do not exceed 165 lb. (75 kg) cargo

weight on the roof luggage carrier.

■

When loading cargo (vehicles with a

moon roof or panoramic moon roof)

Be careful not to scratch the surface of

the moon roof or panoramic moon roof.
