■

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.

●

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 prop-

erly.

Driving the vehicle

The following procedures should be
observed to ensure safe driving:

Driving procedure

4-1. Before driving

Driving

■

Engine speed while driving

In the following conditions, the engine

speed may become high while driving. This

is due to automatic up-shifting control or

down-shifting implementation to meet driv-

ing conditions. It does not indicate sudden

acceleration.

●

The vehicle is judged to be driving uphill

or downhill

●

When the accelerator pedal is released

●

When the brake pedal is firmly or quickly

depressed

■

Restraining the engine <hybrid system>

output (Brake Override System)

●

When the accelerator and brake pedals

are depressed at the same time, the

engine <hybrid system> output may be

restrained.

●

A warning message is displayed on the

multi-information display while the sys-

tem is operating. If a warning message is

shown on the multi-information display,

read the message and follow the instruc-

tions.

■

Restraining sudden start (Drive-Start

Control)

●

When the following unusual operation is

performed, the engine <hybrid system>

output may be restrained.

• When the shift position is shifted from R

to D, D to R, N to R, P to D

or P to R

includes M) with the accelerator pedal

depressed, a warning message appears

on the multi-information display. If a

warning message is shown on the multi-

information display, 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 posi-

tion may not be changed.

●

While Drive-Start Control is being acti-

vated, your vehicle may have trouble

escaping from the mud or fresh snow. In

such case, deactivate TRAC (



P.244)

to cancel Drive-Start Control so that the

vehicle may become able to escape from

the mud or fresh snow.

■

Breaking in your new Lexus

To extend the life of the vehicle, observing

the following precautions is recommended:

●

For the first 186 miles (300 km):

Avoid sudden stops.

●

For the first 621 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 for

extended periods.

■

Drum-in-disc type parking brake system

Your vehicle has a drum-in-disc type park-

ing brake system. This type of brake system

needs bedding-down of the brake shoes

periodically or whenever the parking brake

shoes and/or drum are replaced. Have your

Lexus dealer perform the bedding down

operation.

■

Operating your vehicle in a foreign

country

Comply with the relevant vehicle registra-

tion laws and confirm the availability of the

correct fuel. (



P.388)

■

Brake pads and discs (vehicles with

manual type head restraint)

The brake pads and discs are designed for

use under high load conditions. Therefore,

brake noise may be generated depending

on the vehicle speed, braking force and

vehicle environment (temperature, humid-

ity, etc.).

WARNING

Observe the following precautions.

Failure to do so may result in death or

serious injury.

■

When starting the vehicle

LC500: Always keep your foot on the

brake pedal while stopped with the

engine running. This prevents the vehicle

from creeping.
LC500h: Always keep your foot on the

brake pedal while stopped with the

“READY” indicator is illuminated. This

prevents the vehicle from creeping.

144

4-1. Before driving

WARNING

■

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.

●

LC500h: The driver should pay extra

attention to pedestrians when the vehi-

cle 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

vehicle proximity notification 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.

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 engine <hybrid system>. Turning

the engine <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 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 vehi-

cle in the normal way:



P.338

●

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.162, 169)

●

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 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 fail-

ure, 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.

145

4-1. Before driving

Driving

WARNING

●

Sudden acceleration, engine braking

due to shifting, or changes in engine

speed could cause the vehicle to skid,

resulting in an accident.

●

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 position

●

LC500: Do not let the vehicle roll

backward while a forward driving posi-

tion is selected, or roll forward while

the shift position is in R.

Doing so may cause the engine to stall

or lead to poor brake and steering

performance, resulting in an accident

or damage to the vehicle.

LC500h: Do not let the vehicle roll

backward while a forward driving posi-

tion is selected, or roll forward while

the shift position is in R.

Doing so may result in an accident or

damage to the vehicle.

●

Do not shift the shift position 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 position to R while

the vehicle is moving forward.

Doing so can damage the transmission

and may result in a loss of vehicle con-

trol.

●

Do not shift the shift position to a driv-

ing position while the vehicle is moving

backward.

Doing so can damage the transmission

and may result in a loss of vehicle con-

trol.

●

LC500: Changing the shift position to

N while the vehicle is moving will dis-

engage the engine from the transmis-

sion. Engine braking is not available

when N is selected.

LC500h: Changing the shift position

to N while the vehicle is moving will

disengage the hybrid system. Engine

braking is not available with the hybrid

system disengaged.

●

Be careful not to change the shift posi-

tion with the accelerator pedal

depressed. Changing the shift posi-

tion to any positions other than P or N

may lead to unexpected rapid acceler-

ation of the vehicle that may cause an

accident and result in death or serious

injury.

After changing the shift position, make

sure to confirm the current shift posi-

tion displayed on the shift position indi-

cator inside the meter.

■

Brake pad wear

If any of the following situations occurs,

have the brake pads visually checked and

replaced by your Lexus dealer as soon as

possible.

●

If the thickness of the brake pads

exceeds the brake pad wear limit when

visually checking all four brake pads

(for the brake pad wear limit, refer to

P.392)

●

If “Brake Pad Wear Visit Your Dealer”

is displayed (only the right-side pads

can be detected)

Rotor damage may result if the pads are

not replaced when needed. Moderate

levels of the brake pad and disc wear

allow enhanced braking power. As a

result, the discs may wear more quickly

than conventional brake discs. Therefore,

when replacing the brake pads, Lexus

recommends that you also have the

thickness of the discs measured. It is dan-

gerous to drive the vehicle when the

wear limits of the brake pads and/or

those of the brake discs are exceeded.

146

4-1. Before driving

WARNING

■

When the vehicle is stopped

●

LC500: Do not race the engine.

If the shift position is any position other

than P or N, the vehicle may acceler-

ate suddenly and unexpectedly, caus-

ing an accident.

LC500h: Do not depress the acceler-

ator pedal unnecessarily.

If the shift position is any position other

than P or N, the vehicle may acceler-

ate suddenly and unexpectedly, caus-

ing an accident.

●

LC500: In order to prevent accidents

due to the vehicle rolling away, always

keep depressing the brake pedal while

the engine is running, and apply the

parking brake as necessary.

LC500h: In order to prevent acci-

dents 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.

WARNING

●

LC500: Always apply the parking

brake, shift the shift position to P, stop

the engine and lock the vehicle.

Do not leave the vehicle unattended

while the engine is running.

If the vehicle is parked with the shift

position in P but the parking brake is

not set, the vehicle may start to move,

possibly leading to an accident.

LC500h: Always apply the parking

brake, shift the shift position to P, stop

the hybrid system 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

position in P but the parking brake is

not set, the vehicle may start to move,

possibly leading to an accident.

●

LC500: Do not touch the exhaust

pipes while the engine is running or

immediately after turning the engine

off.

Doing so may cause burns.

LC500h: Do not touch the exhaust

pipes while the “READY” indicator is

illuminated or immediately after turn-

ing the hybrid system off.

Doing so may cause burns.

■

When taking a nap in the vehicle

Always turn the engine <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 engine <hybrid system> overheat-

ing. Additionally, if the vehicle is parked

in a poorly ventilated area, exhaust gases

may collect and enter the vehicle, lead-

ing 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

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 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.

NOTICE

■

When driving the vehicle

●

Do not depress the accelerator and

brake pedals at the same time while

driving, as this may restrain the engine

<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.

■

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 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.

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, transmis-

sion, differential, etc.

●

Lubricant condition for the propeller

shaft, bearings and suspension joints

(where possible), and the function of

all joints, bearings, etc.

If the shift control system is damaged by

flooding, it may not be possible to shift

the shift position to P, or from P to other

positions. In this case, contact your Lexus

dealer.

■

When parking the vehicle

Always set the parking brake, and shift

the shift position to P. Failure to do so

may cause the vehicle to move or the

vehicle may accelerate suddenly if the

accelerator pedal is accidentally

depressed.

Cargo and luggage

Driving

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-
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.150)

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.386)

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

WARNING

■

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.

Calculation formula for your
vehicle

A
B

150

4-1. Before driving

In this condition, if 2 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.

■

Total load capacity and seating capacity

These details are also described on the tire

and loading information label. (



P.325)

Vehicle load limits

Vehicle load limits include total
load capacity, seating capacity,
towing capacity and cargo capac-
ity.



Total load capacity (vehicle
capacity weight):



P.386

Total load capacity means the com-
bined weight of occupants, cargo
and luggage.



Seating capacity:



P.386

Seating capacity means the maxi-
mum number of occupants whose
estimated average weight is 150 lb.
(68 kg) per person.



Towing capacity

Lexus does not recommend towing
a trailer with your vehicle.



Cargo capacity

Cargo capacity may increase or
decrease depending on the weight
and the number of occupants.
